My Math Tutor is a Real Demon

Monday...

“Mr. Gracey... do you know what this is?"

“Um... uh... a letter from the governor...?"

When those words left his lips, he almost immediately cringed at himself. Did he really make a joke? And in a serious situation such as this? Was he trying to lose all credibility as a person? Assuming he had any left, anyway...

Galendale University. When he originally got accepted to go to this college, he was ecstatic. Galendale was his first choice, and was where he dreamed about going throughout his high school years. Every day he studied hard and worked harder, all with the hopes of learning at such a prestigious establishment.

But when you go to the best law school this side of the country, it is expected that you yourself are also the best. Galendale does not take students who are bad, good, or even exceptional. No. They take students who are damn near perfect.

Leonardo Gracey was a lot of things... but 'perfect' is not one of them. He's not even close.

He was tall, but not the kind of tall that exudes athletic prowess, instead being a bit more... lanky. Honestly, the thought of working hard on a football field or basketball court made his body quiver with pain! He did that whole 'Be a member of several different sports teams cuz your parents signed you up for them' thing in middle school! No more of that, thank you!

His shaggy hair was this dusty brown, typically running between chestnut at its brightest, and burnt umber at its darkest. His eyes meanwhile were this surprising shade of blue. They were probably the brightest aspect about him.

Well, aside from that charming grin of his.

What Leonardo – or just Leo to those who knew him – may have lacked in physical strength, he more than made up with in terms of comedy. He was the type of person who always had a joke for any situation he was in, no matter what. Sure, there may always be someone smarter than him, someone taller, someone stronger, and maybe even someone better-looking... but no one – no one! – was funnier.

And he'd argue he had better looks than most of the people around him...

But comedy was not why he was going to Galendale University, and his attempts at comedy did little to amuse the woman across from him. She wasn't even the slightest bit entertained.

Sitting at this desk, a cold gray light peered through the windows behind a woman. She was older than him by, what, twenty or so years? A human woman with black hair tied back into a bun, and these cold, unfeeling brown eyes resting beneath glasses. She stared at Leo without a hint of compassion, appearing more tired and bored, if not outright dull. But she was – currently – the most important woman in his life. Not because Leo liked her or anything, no, but more because of what she could do for him.

Or – more accurately – what she could do to him.

Her name was Susan Hayes, better known as Professor Hayes... and she was Leonardo's Calculus teacher. Specifically, Calculus II!

As if that minute difference means anything...

“Mr. Gracey," said Susan as she palmed the piece of paper on her desk, “While your jokes may liven up the classroom, they mean little in my office. Please, look down at the paper and tell me what you see..."

“Aaaah..." he sighed, partially in frustration, partially in defeat.

When he looked down, what sat before him was this class' syllabus. It detailed everything he could expect from the course, with it all being painstakingly detailed. Every assignment, every test, every quiz, every lecture had been written down on this paper, and given out to all the students in class. Prof. Hayes was a very stringent woman, one who was very thorough and detailed. She wanted to make sure all of her students knew exactly what would come during their semester with her, to the point that she even marked how much percentage of their overall grade each item equated to.

And – unfortunately – it was somewhat lopsided.

Every assignment, every test, every quiz, every everything, amounted to only 40% of their overall grade. So if you were to get an A+ on almost everything, you'd still completely fail the class. Where did that other 60% come from? Well, it was what Prof. Hayes was currently tapping upon.

The final exam.

“You understand why I called you here today, right, Mr. Gracey?" asked Prof. Hayes, causing him to sigh.

“Y-yeah..." he replied whilst gazing to the side.

“Mr. Gracey..." she muttered before straightening up, “I can see you are a brilliant young man. In the areas you are passionate about, you excel. However, in the areas you don't care for, you coast by on them... almost to a lazy degree. And that – unfortunately – has negatively affected your grade in my class. I will be blunt with you; so far, you have amassed a series of Cs, Ds, and Fs. Enough to stay in this class, but far from enough to pass. Now we reach the end of the course, where you have only the final exam to look forward to. I don't think I need to tell you what may happen if you fail, right?"

“N-no... I get it..." Leo muttered as he palmed his head, “If I fail the final exam, I'll fail the class as a whole..."

“No..." Prof. Hayes answered, much to his confusion, “It's actually worse than that. Your grades have been so poor... that even if you were to pass the final exam with a C... you'd still fail my class."

“Wh-what?"

“You'd need a B at least if you wanted to break even. Anything below that, and you'd be forced to take this class again..."

Leo stiffened in place, his eyes wide as his expression turned blank. He knew his grades in this class were poor... but he didn't think his situation was this dire! And Prof. Hayes said it without a hint of remorse! Guess when you've been teaching college classes for decades, you steel yourself for conversations like this.

“Gaaaah... crap..." muttered Leo as he slumped back in his chair, the weight of the situation falling upon him, “So... like... what? Am I boned then? I just... have to scrounge up the money needed to try and take this course again?"

“I wouldn't say that..." Prof. Hayes answered with a shake of her head, “You just need to make sure you pass the final exam with a B- or above. Anything less will result in failure."

“Aaah... and how do you propose I do that...?" asked Leo as he looked at his professor, watching as she tilted her head in response.

“You study. You study hard..."

…

Study? Tch! Yeah right! She said it as if that was easy! As if all he needed to do was whip out his laptop, his textbooks, his bevy of notes that he totally took himself and totally didn't source from his fellow classmates, and just spend all day and all night reading them all until his eyes bled! When was his final exam again? One week from now? He had one week to – somehow – perform a complete 180 when it comes to his views on mathematics! Or – at the very least – do well enough to get a B-... and even that appeared insurmountable!

Putting it lightly... Leo was not having a good day.

Willington: The city of Fallen Angels! Well... it was more like the city of bridges if you were to ask him! It was a giant and sprawling jungle of concrete and steel, with cars driving at all hours of the day, and trains running just as frequently. Densely packed with buildings and people, it was virtually impossible to not bump shoulders with someone... especially when riding a bus like he was.

The vehicle rumbled beneath Leo's feet as he clung to the handle bars overhead. The bus was packed with people, making movement difficult. To his right there was a pregnant woman sitting down. To his left were two men bickering about sports. All the while in the back, someone was playing their music a bit too loud. Leo could hear it even through his headphones...

But with all the people talking, the music playing, and the general sounds of the bus he was in, the young man couldn't stop thinking about his conversation with his professor. The one good thing about Prof. Hayes' apathetic attitude, was the fact that he never felt like she disliked him. Quite the opposite; the fact that she called him to her office in the first place showed that she wanted him to pass. This was his last chance. If he failed, well... he couldn't fail. He didn't have the money needed to take that class again!

If he wasn't stressing out before, he sure as hell was stressing out now!

Prof. Hayes' only advice was that he should study. Yeah, as if that would work. The sad truth is... he had attempted studying before! But like his professor said, he just didn't have the drive needed to learn math. When it came to aspects he cared for, studying was as easy as breathing. Information was practically glued to his brain, if not welded to it! But when it came to things he couldn't care less for, Leo's brain may as well have been transparent: The information just went straight through it!

“Gah... this bites..." Leo muttered, his face growing long as he leaned up against the window in front of him, “Gggghghh..."

Outside, the many buildings of Willington bled by as the bus he was on made its various stops. In Leo's head, he couldn't help but to fret how majorly he fucked things up. He already barely passed Calculus I; why didn't he focus on his studies in Calculus II to make sure this didn't happen again!? Now he was looking at an almost assured failure, where he could kiss his dreams of working in law goodbye.

It made him tremble to his feet just thinking about it...

What he needed was help. Studying on his own wouldn't work; he needed a tutor. But who? Hell, was it even possible to hire a tutor with such little time left? He had only one week until the final exams! And even if he did find and hire a tutor, whose to say he'd be able to retain the information he was taught? He barely remembered what Prof. Hayes was teaching him!

But that didn't get into the biggest challenge of hiring a tutor, and that would be the fact that Leo was broke. He had a job, yes, but between college expenses, his (shitty) apartment, and, ya'know, things like food, he didn't really have a lot of money to spend frivolously. From last he checked, any tutor worth hiring did not hire for cheap! Definitely not for college students...

Crap! There had to be a cheap alternative! Someone, somewhere had to be willing to teach a broke college student calculus! But who? And how would he find them? Ugh!

Now arriving at Mordredus Road! Now arriving at Mordredus Road!

When the intercom system played off the next destination, Leo perked up. Mordredus Road? He passed by it all the time when taking this bus – the Z-Line – home to his apartment. The road always appeared empty, and no one ever got off, or on the bus at this spot.

That is until now...

Shufffle! Push!

“Hey! Watch it!" Leo shouted.

His music playing in his ears, the young man was pushed by larger bodies that were in a rush to get off the bus. In turn, they accidentally forced him off the bus since he was standing close to the door! Leo stumbled, his body twisting... before he fell on the concrete ground with an audible--

Thud!

“Oof!?"

Leo sprung up... just in time to hear the bus' doors close shut, followed by the telltale sounds of--

Cran-Crank!

“Whoa! W-wait! D-don't go!"

Too late!

The bus began driving off, causing Leo to stumble forward with his eyes wide. Struggling to his feet, he attempted to chase it down, but it was like the vehicle went from zero to one hundred! It peeled away from the young man, leaving him in its dust as it drove off to the distance, and eventually vanished from sight.

Standing there, his mouth agape with shock, Leo wondered how he could be in this situation. That confusion quickly shifted into anger as he turned around to face the road. Who were the rude fucks that pushed him off of the bus in the first place!? This was their fault!

Well...

The sidewalk was empty. The people who pushed him off the train were gone; vanished... almost as if they were never there.

Leo looked at his surroundings in confusion, his eyebrow raised. Um... where was everyone? Willington was the type of city that was always – always – filled to the brim with people. But here, it was quiet to the point that he could hear himself breathe.

That's... not normal...

Straightening up further, the young man tugged on his backpack, his head looking left and right in a quizzical and suspicious manner. This place... it was called Mordredus Road, right? What an odd place. Not only was the sidewalk empty, not only were the roads nearly empty, and not only was the air oddly quiet, but the place's style even felt... archaic. Instead of office complexes, construction zones, skyscrapers, or whatever else have you, the storefronts here appeared like your basic and small shops and stores. A bookstore, a cafe, an apparel store; places that felt out of place among the hustle and bustle of city life.

But, still, where was everyone?

Leo stumbled around this curious – and eerie – little road, searching for any other sign of life. But, again, there was nothing and no one. Nothing and no one... save for this oddly lavish building in front of him.

Straightening up, Leo turned and dropped his eyes upon a strange storefront. Most buildings in Willington were modern and industrial, leaning into a more business and professional mindset. But not this place. This building in front of him? It looked old.

The walls were weird, feeling otherworldly with its Gothic architecture. Elegantly carved, it exuded a sense of majesty only matched by churches and cathedrals. Only, except for being white and opulent, it was a more reddish color, making it feel... ominous. And on the corners of this building there appeared to be an idol, that of a reptile sprouting out from the center of a flower.

Oh, yeah, and the windows of this store were tinted. That's not sinister in the least bit!

Leo stared at the building, confused by its existence. It reminded him of a small bookstore next to his apartment, but even that was a part of a larger complex of stores. This shop was wholly unique however, and easily stood out from the rest of the outlets beside it.

Was it him, or did he feel like there was a strange presence exuding from this building? Almost like some ominous force was being forced out from its seams. It drove him in closer, causing him to place his hand on the busts outside of the store, where that strange presence felt even stronger. It pushed through him, made his body tense up and caused his chest to swell, almost like he was breathing in something... noxious.

Leo gritted his teeth. No. Whatever this place was, he had no business here. He just needed to go back to the bus stop, and wait for the next Z-Line to show up. It was going to take a while, so he might as well find a video to watch and start waiting! So Leo turned around, took a step forward, and--

Boing-Boing!

Walked into someone.

Walked into someone's chest. Someone's big, soft, busty chest.

Leo flinched and pulled back, his eyes wide as he palmed his head. Appearing dazed for a moment, it took him a few seconds to settle his mind. When he did, he gazed forward... and his eyes grew wide as his head tipped back.

Standing before him was a woman. A very tall, very voluptuous woman. Taller than him in fact. About eight feet tall if he were to estimate! She had dark skin, long raven hair that messily spilled from her sunhat, and wore a white slingshot dress that sported her amazing cleavage... and had various golden adornments on it. A tight gold belt, a tight gold choker, golden bangles on her arm; it all made her feel like some sort of Egyptian priestess.

She looked down upon Leo with a curious and concerned look in her purple eyes, while he stared back with his mouth agape. For several moments he stood there, incapable of speaking... before suddenly realizing what happened. He just walked into this woman's breasts!

“S-sorry!" he apologized as he stepped back, “I-I didn't see you there!" he then added on with a wry grin, “Please don't sign a sexual harassment charge!"

Now? Even now he was attempting to crack jokes? That would only increase his chances of getting a sexual harassment charge!

But the woman didn't say a word. Instead, she tilted her head at him, as if scanning the young man who stood before her. He said nothing, instead straightening up as he gazed at the woman more. It was now that he realized she had the pointed ears of a feline, and the long, slender tail of one too. She was a hybrid, specifically a catwoman.

“Is... something wrong...?" asked the woman, making him stiffen further, “Did you... want to come to my daughter's shop...?"

“Your daughter's... shop...?" Leo repeated as he turned around.

This place was a shop? One that belonged to this woman's daughter? He shook his head and was about to answer with a curt 'no'... but the woman started walking past him, where she entered the store. She was so tall – again, she was about eight feet tall – that she had to bend over to properly enter the store.

As she pulled the door open, a chilling and baleful air flowed out of it. Leo fidgeted in place upon feeling such a force while his eyes curiously peered inside. There was a small walkway immediately on the other side of the door, one that led to curtains as if entering into some sort of gentleman's club.

His face quivered at the sight, watching as the mysterious catwoman walked up towards the curtains at the back. Again she had to bend down in order to enter it, but she turned to face Leo as she did so.

“You look like you could use some help," she said with this inviting smile on her mature lips, “Would you... like some aid with your issues?"

“I...?" Leo answered, before cutting himself off.

The woman didn't wait for his answer, instead entering the store proper. That left Leo standing there outside of this strange place, his face blank as he wondered what he should or shouldn't do. He wanted to head back to the bus stop... but even if he started sitting there, he'd be waiting for upwards of 30 minutes to an hour for the next bus, depending on how generous life was being to him right now.

Going by that, he'd definitely have to wait that extra hour. Ugh.

With time to kill – and being more curious than he'd care to admit – Leo walked into the store. Hey, if this ended up being some sort of trap and he got killed for his curiosities, at least he wouldn't have to deal with Calculus II, right? There was some silver lining to this!

Morbid though it was...

Walking through the curtains on the other end, Leo entered a room where the floors were laden in velvet rugs. Around him were rows upon rows of shelves, each one filled with items and trinkets of an unknown origin. Jars filled with questionable objects, talismans of esoteric power, and books that seemed to... squirm. Where was he?

“Mr...?" said the mysterious catwoman as she sat behind the counter at the back of the store, “Are you going to tell me what ails you...?"

“Wh-what? Me...?" said Leo as he pointed at himself, “S-sorry... uh... but who are you...? And..." he looked around again, “Wh... what is this place?"

“Hyuhyuhyu~ Welcome to Ryoko's Boutique. It is my daughter's store," said the catwoman as she leaned up on the desk, her huge breasts resting upon its flat surface, “My name is Hasshaku. It is nice to meet you, Mr...?"

“Gracey..." he replied as he approached her, “My name is Leonardo Gracey. But, please, just call me Leo."

“Leonardo... Gracey..." said the woman as she prodded her fingers together... before smiling and nodding, “Lovely name, Mr. Gracey. Hyuhyuhyu~"

A blush formed on his cheeks as the woman addressed him, and he briefly looked to the side. Maybe it was her height (have you ever met such an abnormally tall woman?), or perhaps her huge breasts that her dress seemed to emphasize, but he couldn't bring himself to look at her. Still, he walked up to her at the desk, watching as she straightened up on her chair to face him.

“Would you like to tell me what ails you, Mr. Gracey?" asked Hasshaku, to which he sighed.

“I... um... I... uh... well..." he mumbled... before shrugging his shoulders and throwing up his hand, “Eh... fuck it... there's no point in holding it in. It's not like you could do anything about it..." his body slumping over, he leaned against her desk, “I'm in danger of failing my calculus class. If that happens, I won't be able to work towards my major in law, because calculus is a prerequisite. The final exam is in one week, and I need to pass it with a B at least if I want to pass this class. If I get a C or below, well..." he shook his head, “Fuck... I'm so boned..."

Ever since he left Prof. Hayes office, these thoughts have stewed in his head. Now that he said it out loud however, it felt like the weight of the situation fell upon him. Leo's shoulders slumped over further, and a defeated groan left his lips. This one class – this one class – held the key to his future. And it wasn't looking bright...

Defeated and dejected, Leo pulled his head up, bringing his gaze back to Hasshaku... and the smile she was sporting.

“I see," said the catwoman as she began prodding her fingers together, “Hyuhyuhyu~! If I may, Mr. Gracey, could I give you some advice?"

“I..." he mumbled back, before shrugging his shoulders, “I don't see why not... do... do you have something in mind?"

“What you need, Mr. Gracey, is a tutor~" said Hasshaku, this alluring smile spreading on her lips, “Someone who will sit with you and help go over the materials of your course until they are baked into your skull. But... a normal tutor wouldn't be enough for you. Not enough to teach you what you need in one week~"

“Well... yeah... I do need a tutor..." Leo mumbled with another shrug of his shoulders, “But I don't... really have the money to pay a tutor. Tch... what tutor would be willing to help my broke ass out...?"

“Weeeeeell... not any mortal tutor~" Hasshaku answered... taking Leo aback.

“Come again?"

The voluptuous feline didn't answer, instead giggling in this mature and womanly manner. Standing back, Leo watched as she walked out from behind her desk, her hips swaying from left to right as she traveled over towards a nearby bookcase. On it were hundreds of books, almost all of which looked incredibly old. Hasshaku placed her hands on these books, before dragging her palm along their spines as she searched for one.

“In times long since passed," said the catwoman, “Mankind was known to communicate with beings of an... otherworldly origin in order to gain knowledge they could not so easily obtain otherwise. For who better to teach us than those whom time is of no burden?"

“I...? What...?" replied Leo, not really understanding what Hasshaku was talking about.

Again, the feline did not answer him, instead replying with more giggles as her hand came to a stop. Gripping one of the books before her, she pulled it out of its slot then walked over towards Leo. He stiffened up as this towering catwoman loomed above him, gazing under her sunhat towards her face as it was cast in shadows. Leo could no longer see her lips, only the glow of her inscrutable purple eyes.

“Do you see this...?" asked Hasshaku as her hand dragged upon the surface of the book she held.

He looked down, coming face to face with a massive tome. An aged massive tone. It was black, with silver metal lining its spine and edges, as if it were bound in light chains. And in the middle of it was a purple flower with a serpent extending from its surface.

Wait... doesn't that sound familiar?

“What is this...?" Leonardo asked.

“This is the Book of Mordred," Hasshaku answered, “Contained within it is knowledge that goes far beyond your head. Hyuhyuhyu~ I'm sure we could find someone who will aid you."

“Wh... what are you talking about?" Leo asked as he stepped away from the catwoman, “What? You make it seem like this book is..." he looked down, “Like some grimoire or something... that it could summon demons or something..."

He gazed back up. Hasshaku was smiling at him again. Leo stiffened in place and opened his mouth to speak... but the catwoman extended her hand.

“May I see your phone, Mr. Gracey...?" she asked, her voice reverberating in his ears.

Leo gazed up at her with an eyebrow raised, confused by her request... yet acquiescing to it nonetheless. Reaching for his pocket, he pulled out his phone and then walked closer towards Hasshaku. Her purple eyes were locked on his face, her smile spreading wider.

“Right here," she said as she tapped the surface of her book, “Place your phone right here..."

Ugh... this was so stupid! This strange catwoman was asking for his phone, while going on about 'otherworldly beings' or whatever. Book of Mordred? What even is that!? And why was he obeying her!?

Despite thinking that this situation was bizarre and stupid, Leo still gave his phone to Hasshaku. He blamed it on her eyes... or her huge tits. Silently, she thanked him for his phone, before opening it up... without asking for his lock code. He tilted his head in confusion, opened his mouth to ask her what she was doing, but the sudden sound of her tapping away at his phone silenced him. It all happened in only a few seconds – not even a minute had passed – before the voluptuous feline returned his phone to him.

“Here," she said as Leo held his phone in his palm, “That should do it~! Hyuhyuhyu~"

“Should do... what...?" he asked as he looked at his phone... seeing that nothing was out of the ordinary.

“You need a tutor, right? But you lack the sufficient funds to afford one?" Hasshaku answered, “Well... this will help you~! I have given you the phone number to a tutor, one who does not request financial compensation, but something a bit more unique. Her name is Lady Fenrir, and it is important that you give her the utmost respect!"

“Lady... Fenrir...?" Leo replied with an eyebrow raised, “Uuummm... okaaaaaay..."

“Hyuhyuhyu~ I know this may all seem sudden and bizarre to someone like you, Mr. Gracey, but I assure you, Lady Fenrir will be very thorough in your teachings~"

Why did she put such extra emphasis on 'very'? Actually, better question, why was Leo still here!? This store was strange, but Hasshaku was stranger! And, sure, she gave him back his phone and hadn't done anything to him... but he still felt unsettled around her!

He blamed it on her hat. The way it covered her face in shadows save for her eyes and mouth made him feel less like he was talking to a person, and more like he was talking to a ghost.

“Umm... o-okaaay..." Leo mumbled before sheepishly scratching at the back of his head, “Th-thank you for this... or something... I... I guess..."

“Hyuhyuhyu~! Do not mention it, Mr. Gracey," said Hasshaku as her smile grew wider, “I so do love helping lovely young men such as yourself out! Any aid I can offer, I'll gladly oblige!"

'Lovely young men'? Was she flirting with him now? Normally, he'd take that as an offer to flirt back. Buuuuuuuut, Hasshaku was more than just a little weird. This strange catwoman was taller than anyone he ever met, and she spoke of demons and monsters as if they were real. But that's insane! And if that's insane, then she's insane!

Maybe he had been here a bit too long...

“Um... okay... um..." Leo murmured as he continued walking back and away, “Th-thanks for your h-help, Ms. Hasshaku... uh... b-b-but... I think I need to go! Before I miss the next bus!"

Yeeeaaaaaah. That was a good excuse, right?

Thankfully, Hasshaku didn't say a word, instead softly waving goodbye as Leo quickly scurried out of the store. And she continued standing there, her purple eyes locked on the exit... while a door behind the front desk opened up.

“Hm? Mom?"

The towering feline turned around, facing the front desk of the curiosity shop, where her gaze fell upon another catwoman. She was tall – though not as tall as the voluptuous feline before her – with a slender body, dark skin, long raven hair, and cold purple eyes. Wearing a face that was mixed between surprise and indifference, she approached the mature catwoman with her head tilted to the side.

“Ryoko!" said Hasshaku, “How was your day, dear?"

But the younger feline didn't answer. Instead, she wore an accusatory face as her head tilted to the side.

“Mom..." she mumbled, “I know that face you're making..." she looked towards the entrance to her store, “Did someone come in here? Did... did..." she looked back, “Did you hex someone?"

“Hyuhyuhyu~! Me? Hex someone?" Hasshaku answered... before shaking her head as her purple eyes glowed, “Never..."

…

Railway Apartments. Well... at the very least, it was brutally honest about where it was located.

RRRURMMMMBBBBBBLLLEEEEEEEEEEE!!!

From wall to wall, floor to ceiling, his apartment rattled like it was suffering a minor earthquake. It wasn't, mind you. That was just the Blue Line making its evening run.

As expected of Leo's poor luck, the Z-Line didn't show up for like an hour. He stood at that bus stop for what felt like an eternity, a feeling only exacerbated by how empty and silent the street was. If it weren't for his headphones and the admittedly good internet connection, he would have gone insane standing out there for so long by himself!

But it's fine; it's whatever. He was home now, standing at the entrance of his apartment in a slumped over manner. His once formal clothes now appeared rustled and wrinkled, while he wore a face of exhaustion. This is what dealing with the public transit system does to a man.

Leo's apartment was modest in size, being a tad bit larger than average. There was a small kitchen area to the back, a bathroom to the right of the entrance, and his bedroom was separated by a door of its own. And at the back of his apartment was a large window, one that showed the beautiful sight of the nearby suspended railroads.

Railway Apartments was cheap. Why was it cheap? Because it sat so close to the nearby railroads, which were active at all hours of the day. Apparently, people don't want to sleep next to large trains that rumble their home and howl while doing it! Oh well; their loss, and Leo's... dubious gain.

As he entered his home, he dropped his backpack upon his couch, then fell face first into its cushions. A loud groan left him, muffled by his sofa, yet no less telling of how frustrated and doomed he felt. After his little run in with Hasshaku, the realization of his situation continued to nag and eat away at him. He had worked so hard to get accepted into Galendale, only for what? To lose it all because he couldn't pay attention in math classes?

There was no one to blame but himself, and that's what made this so difficult for him!

Rolling onto his back and staring up at his ceiling, Leo wore a defeated face as he pondered his options... few though they were. Again, he could try and study, but that wouldn't do anything. Even if he stuck his nose to the grindstone and read every note he took and every textbook he owned every day for the next one week, he knew it wouldn't stay in his mind. That's just not how he learned.

He needed help. He needed...

You need a tutor, right? But you lack the sufficient funds to afford one? Well... this will help you~! I have given you the phone number to a tutor, one who does not request financial compensation, but something a bit more unique. Her name is Lady Fenrir, and it is important that you give her the utmost respect!

Hasshaku...

Remembering his weird conversation with that tall catwoman, Leo reached down for his phone and pulled it from his hip. This... Lady Fenrir, was it? Hasshaku said she did not ask for money for her services, but something a bit more 'unique'... whatever that means. Hasshaku spoke like this Lady Fenrir was a demon or something, and the price for her aid would be his soul!

HAH! Yeah right!

Angels, demons, monsters; they don't exist. That's just nonsense created by people thousands of years ago who couldn't explain naturally occurring phenomena. This Lady Fenrir wasn't a demon... although she did have a really cool sounding name!

Lady Fenrir. Lady Fenrir. Lady Fenrir. After fumbling through his phone's contacts for a few moments, Leo eventually located her name. How odd that Hasshaku got through his phone's security to give him this number.

Wait... did she give him her phone number? Because the entry for Lady Fenrir's number was completely blank. It was just her name... and nothing else. Not a phone number, not an email address, not even a profile picture. It was just empty.

Confused, Leo scratched the side of his head, wondering if Hasshaku gave him the number or not. He then clicked on Lady Fenrir's name... where nothing happened.

No. Wait. Not nothing; something did happen. Specifically, his phone froze.

“What the...?"

Several more times Leo tapped his phone, trying to change the screen or do anything, but nothing happened. The phone stayed frozen on Lady Fenrir's name... before finally blinking and turning off, rebooting itself. Confused – and now annoyed – he watched his phone boot back up, before dropping it to the side and groaning.

“Fucking... weird cat lady..." Leo mumbled as he put his phone to the side and stood up from his couch, “I need to take a shower..."

Stressing himself out with his oncoming doom would do him no good. He needed a good shower, a good dinner, and a good rest. Tomorrow, he'd hopefully be able to figure out some way of passing his math class. Hey... cheating was always on the table.

Yeah right...

As Leo turned and started heading for his bathroom, his phone began to buzz and shake. It rattled upon his table with enough force to move towards its edge, before coming to a sudden stop. There it sat, still and silent.

The screen turned purple.

…

A good shower, right? Good means things like... pleasant... or nice... or sweet... stuff like that, right? Well, that's not what Leo felt! It was a typical shower, all warm and misty; the kind of shower he was used to taking. But he didn't feel anything close to pleasurable while shower. He felt stressed. Really, really stressed.

Emerging from the shower, Leo began drying himself off. He should have grabbed his casual clothes before coming in here. Now he had to walk over to his bedroom with this towel on. Oh well; whatever. That was the least of his issues right now.

With each passing second, he marched towards his inevitable doom. What was he going to do? Scour the internet for a local tutor who could help him study this in a timely fashion? Maybe ask one of his classmates for some pointers? Just sit there and accept his fate?

That last one sounded the most logical, honestly...

Leo questioned all of his choices as he exited his bathroom, and... hm? Wait... was it him, or was it oddly dark in his living room? Like so dark that he could barely see in front of him. Sure, the sun was starting to set as he got back to his apartment, but it was still day! And didn't he leave the lights on? Why was it so dark!

“I swear..." he mumbled to himself as he stumbled through his dark apartment, “If Francis did this... ugh... he is the worst landlord...!"

Leo stopped. It wasn't as dark in his room as he thought.

Turning slowly, his eyes fell upon the coffee table in the center of his living room. On it laid his phone... and the screen was a dark purple. For reasons he couldn't explain, Leo felt his heart rate spike as a cold sweat broke down his brow. Reaching for his phone and picking it up, he lifted it close and checked it... only to feel an ominous tremble travel under his feet. This wasn't the familiar rumble of a train passing by. This was something else. This was something unearthly.

Flick! Flick! Flick!

“Ah!? What!?"

Pulling back, Leo winced as the lights in his apartment suddenly began flickering on and off. The various objects and knickknacks in his home began shaking too, rumbling as if an earthquake was occurring! Even Leo was struggling to stand as he gazed around in search of an explanation for this... before trapping his gaze on the open spot in the center of his living room.

Right there – right at the spot in front of his desk where he usually worked – Leo saw flames. Dark and purple in color, they sprouted up from the floor, emerging and surging outwards like a vent of fire! And from these flames emerged a door. Black in color, it had spiked edges, a Gothic design, and the symbol of a silver crown in the center of it.

This door – pumping with purple flames and a sinister miasma – hung before Leo who stared back with eyes wide and mouth agape. His legs could no longer support him, causing him to fall back on his butt as he babbled nonsensically. The lights of his apartment finally stopped flickering, remaining on. The trembles ceased too, leaving everything normal... save for the demonic door looming over him.

Click... Twist...

And the door's knob began turning.

Eeeeeaaaaaarrrrrrrk!

The sound of it opening reverberated throughout his apartment, being similar to the deafening howl of a cemetery's gate. On the other end was not another room, or a hallway, or anything like that… but instead a void of darkness. And emerging from the darkness was a woman.

What attracted Leo first was her eyes. In all of his twenty-one years of living, he had never seen eyes as green as hers before. They were greener than fresh cut grass. Greener than the canopies of trees in a rainforest. Greener than open fields on a sunny spring day. Sharp too; her green eyes looked powerful enough to penetrate a person's very being, learning everything she needed to know about them in only a few short moments. When they gazed down upon him, he felt...

Small...

She was a voluptuous woman, her body curvy in all the right ways. These wide hips. These shapely legs. This narrow waist. These curvy shoulders. These buxom breasts. Her body was that of a noblewoman, one with a darker skin tone... and silver-white hair. Long silver-white hair that was split in the side, with curly bangs that hung over her face, while the back was braided into a ponytail that fell all the way to her hips.

There was something... sinister about this woman, which was only amplified by her otherworldly clothing. She was wearing a black dress. A skintight black dress. A skintight black dress that plunged so deep, it came down to her navel. There was even a split at her hip, exposing one of her curvy hips.

And her chest...

The dress wasn't covering her chest. Instead, she wore what appeared to be claws. They gripped her breasts, squeezing them, lifting them, and holding them in place.

Upon her body were various adornments... all of which appeared demonic in nature. Unknown talismans, unknown charms; they hug on her dress, and even around her neck via a necklace. All of which told Leo one thing and one thing alone.

She should not be here.

And yet, this fiendish woman dressed like a demonic witch... had such beautiful green eyes. And those green eyes were looking down upon him.

“You…?" said the woman, her voice regal and refined like a duchess... yet sardonic and indifferent like a superior, “You are the one who summoned me?"

And Leo...?

“Guuuuuuuuuuuuuuuhhh...? HUH!?"

Leo couldn't believe this was happening!

He sat there, naked with only his towel to cover his manhood. This woman stood above him, where she moved her fists to her hips in this dominating pose. Behind her, the gateway to the dark void she emerged from pulsated with a sinister aura. It flowed outwards through his apartment, sending a cold chill that traveled up Leo's spine.

He attempted to speak, but only childish and confused babbling left him. The woman in front of him was not amused. Wait, she wasn't human! She looked human – she had skin and the body type of a human – but she wasn't human. It was those ears of hers, and how pointed they were.

She was an elf! A dark elf!

“Are you going to say something...?" she asked, her tone tainted with annoyance, “Or just sit there with your mouth agape like a blithering babe?"

“WHAT THE HELL!?"

Leo stumbled to his feet, being sure to grip his towel in order to cover his manhood. Hesitantly yet courageously, he drew closer to this woman, his eyes looking her up and down. She was... REAL!? For a moment, he thought that maybe – juuuuuuuust maybe! – he had slipped out of his bathroom, and bashed his head against, like, his sink or toilet or something. But, no, that's not what happened. This woman – this demon – was standing in front of him! She even emerged from that door to nowhere!

That door...

Leo looked past the woman towards the door, gazing briefly into its mouth of infinite darkness. She emerged from... THAT!? What even is 'that'!? Where did it lead to? Hell!?

The existential dread of this situation began falling upon him; the realization of what he had done and its full weight all collapsing onto his shoulders. This dark elf emerged from thin air; he had summoned a demon! Demons were real! If demons exist, then that implies the existence of angels! And angels imply the existence of God, or gods!

Was Leo an atheist? Well... kinda? He never really put too much – or any – thought into any of it. Yeah, he would've preferred going to Heaven after death if it existed, but he didn't fret about it all day. Like, say, his aunt who was super religious and went to church every Sunday. Then he had one of his classmates who wouldn't shut up about how fake religion was in all forms. In a way, Leo saw himself as being someone in the middle.

BUT ALL THAT WAS THROWN OUT THE WINDOW RIGHT NOW!!!

He came close to touching this dark elf, causing her ears to twitch and her head to turn. Looking up, he realized far too late that this was a bad decision. He didn't even get the chance to speak before she brought up her foot, and--

Jab!

“ACK!?"

Placed it on his chest, forcing him down to the floor and pinning him there. Leo struggled against her, but despite her feminine curves and similar height to him, she appeared heavier than steel! Her heeled foot ground against his chest, forcing out groans of pain as he placed his hand on her ankle in an attempt to force her off.

It wasn't working.

“Gah!? Glhhkk...! I-it hurts...!" he grunted, while the dark elf bent over... causing her chest to bounce in his face.

“Did. You. Summon. Me?" she asked, her tone no-nonsense.

Leo didn't know what to say. Could he say anything? A fucking demon was pinning him to the floor! And from the looks in her... beautiful verdant eyes, she had no qualms outright killing him if he said something out of line! Wait... what is it Hasshaku said when she gave him that contact?

Her name is Lady Fenrir, and it is important that you give her the utmost respect!

Right! That's it! Respect! She needed respect! He is dealing with a demon, and from the looks of it, a powerful one at that! If he wanted to live, he'd better start groveling!

“Lady...! Ackh! Lady Fenrir!" he called, causing the dark elf to tilt her head in the opposite direction, “Th-that's your name, r-right? Rrgggh!?"

Her verdant eyes slid inwards, becoming deadly knives as she glared at him. For a brief moment, her stance shifted, becoming less domineering and strict as she pulled her foot away from his chest. It allowed Leonardo to gasp, panting for air as she continued standing above him. A few more times her head swayed from side to side, looking him over in an incredulous manner, before sighing dismissively.

“Correct," she said as she placed her hand on her chest and pushed it out in a powerful stance, “I am Lady Fenrir: Grand Mage of the Mordredus Wizard Court. It is your pleasure to make my acquaintance. Now then... for what reason have you to summon the likes of I?"

Her announcement came in time with a powerful upsurge of miasma which poured through her open door, as if heralding her appearance. It flowed throughout Leonardo's apartment, sending shudders down his spine. This was happening. This was actually happening! This woman was real! A real demon!

Oh shit! Holy shit! Wait? Holy shit? There wasn't anything holy about this! This was literally satanic! He was sitting before a real dark elf. This wasn't some good cosplay, or his imagination; this was real!

Wait? Does that mean he's going straight to Hell for, ya'know, summoning a demon!? No, no, no! Now's not the time to question such things! If he wanted to survive long enough to even fear the afterlife, he had to give Fenrir her respect... and make his request!

“Um...! I...! Ugghh..." said Leonardo, causing the dark elf to glare at him again, “Gaah!? I-I mean! I--! I uh...! Uhh...!"

Shit! Shit shit shit! He was babbling again! And she did not look pleased by it! Either she was going to kill him on the spot, or turn around and return to her domain, leaving him here alone. He didn't know which one was worse!

So Leonardo stood up... only to immediately fall back on his knees before her.

“Lady Fenrir!" he cried, “I...! I need your help!"

“I presumed as much," said the dark elf as she tilted her head at him, “So... what is it you request of me?"

A cold sweat broke upon Leonardo's brow, streaking down along the side of his head and falling to the floor. When he looked up, he saw Fenrir's perfect feet. When he looked further up, he saw her domineering gaze. Both worked together to subjugate him. He couldn't believe he was about to say this, but dammit, he had come this far already!

“Lady Fenrir..." Leonardo said as he looked up at her... before placing his hands together like a priest praying to their god, “Can you help me with my Calculus class!?"

Silence...

For several moments that felt like an eternity, Leonardo and Fenrir looked at one another. His face was pleading, desperate yet hopeful. Hers was apathetic, indifferent, and domineering. It left him wondering if he had spoken, or if he merely imagined he had spoken.

“What...?"

Fenrir's voice broke the silence, sending a jolt down Leonardo's spine. For a moment, she looked at him with that same face of apathy and power... before letting it break. Her expression shifted into one of genuine bewilderment as she raised an eyebrow and scrunched up her face. She then opened up her mouth – once, twice, thrice – only to close it each and every time without saying a word.

Leonardo meanwhile remained on his knees with his hands clasped together in that beggar's pose. He knew his request was... unorthodox, but he was really at his wits end! A demon – a real demon – was standing in front of him, and she may be the only person in the world who could reverse his fate!

Assuming she didn't just kill him outright.

Grrrrrrrvvvvvvv!

And that seemed to be likely!

Fenrir's hand clutched at the air, as if she was holding something invisible. This caused a series of dark and sinister magics to start flowing from her palm, taking the form of a cackling energy. It ran through various shades of purple – mauve, indigo, magenta, fuchsia – and pulsated before twisting and morphing into arcane symbols. And from these symbols...

Fwweeeaaaaaam!

“What the...?"

A bright light emerged beneath Leonardo's body. Confused, he stared down at it...

Sllliiiittthheeerrrrr...

Only for his eyes to grow wide.

SNAP!

“OOFF!?"

Emerging from the bright light was a long, thick, spongy, tentacle! Akin to the appendages of an octopus or squid, this thick tendril had various suction cups that ran along its underside, and was black in color. Wrapping around Leonardo's waist, it squeezed him tight then tugged him to the floor, flattening him against it as his cheek ran along its surface. Fenrir meanwhile continued standing above him, her hand curling through the air as she tightened the grip of the tentacle around him further.

“Is this a joke...?" she asked, her voice booming in his ears.

“N-no! Grrrghg! N-not a joke...!" Leonardo eked out through strained lips, “I-if this was a joke...! Aagggh!? I wouldn't be so stupid to try and pull a prank...! Ggggh! On a demon!"

“Hmm... doubtful," Fenrir replied as she tilted her head at him, “You mortals are notoriously foolish."

“I don't doubt that!" Leonardo retorted, “But this isn't... ack! This isn't a joke! I'm being serious! P-pleaseeeeee...!"

The dark elf did not seem to believe him, which wasn't good. Her tentacle was starting to squeeze tighter. If this kept up, she'd snap his spine in two! And for obvious reasons, Leonardo quite liked his spine! He quite liked living as a whole!

But Fenrir didn't believe his words. How was he supposed to get out of this situation? Respect? Respect! He needed to give her respect! But if begging already wasn't enough, how was he going to respect her when she was killing him!? All Leonardo could do was gaze up, where he saw Fenrir's foot just a few feet away from his face.

Wait... well... that's a form of respect, right? It might not be the most graceful showing of respect, but in his position, he didn't really have a lot of grace! Besides, the last thing he wanted was for the police to find him dead in his apartment, butt naked with a crushed spine! Even in death that wasn't a conversation he was ready to have!

So – fighting through all the pain of his body being squeezed – Leonardo forced himself forward as best he could. Fenrir watched him move closer, but said nothing, being silently curious to what he was about to do. He positioned himself above her foot, gazing upon its immaculate shape and contours. She was wearing sandals that exposed her feet in all of their elegant glory.

Now, look, Leonardo is not a feet guy. To the people who do like feet, more power to you! But it's just not his thing! However... when the foot belongs to a woman as beautiful as Fenrir, and said woman is trying to kill you... well...

He could imagine worse feet to--

Chu...

Leonardo pursed his lips, kissing Fenrir on the foot. The feeling caused the dark elf to let her hand stop clutching at the air, making the tentacle around his waist to loosen its grip. Freed from its painful squeeze, he gasped for breath... but that didn't stop him from pursing his lips, and--

Chu...

Another kiss to Fenrir's foot.

“Haah! Lady Fenrir," he said as he hung his head low, “I... humbly request your aid. Please, teach me calculus. You're the only person who can help me!"

Again, there was a deafening silence. His eyes closed, Leonardo kept his head turned down towards Fenrir's feet, fearing what her response would be. This could end in one of three ways: she helped him, she left him, or she killed him. A 66% chance of failure? Those were not good odds! All he could do was sit there and hope. Hope that...

“Aaaah... I can't believe this..."

Fenrir helped him...

Slliittttheeerrrrr! Sliiiiiiiddeeeee!

“Gah...!"

The tentacle around Leonardo's waist retreated, slithering back into its portal, where it vanished. Soon after, the magical light around his body disappeared as well, returning his floor to normal. Gasping in awe, the young man swept his eyes around his home... before tepidly bringing it back up to the dark elf standing above him.

She had her face in her hand as she wore an exasperated face. All of the regal poise and queenly grace she once owned had vanished completely, replaced with sheer disbelief. Leonardo moved to speak, but Fenrir suddenly turned, facing the gateway behind her. A fountain of that dark and purple fire emerged from the base of the door, allowing it to sink back into the unholy depths from which it emerged from.

With the doorway gone, Leonardo's apartment had returned to normal. Ya'know, save for the voluptuous dark elf of demonic origins who remained in its wake!

He looked up at her, watching as she remained befuddled by the situation she was in. The dark elf was still shaking her head as she began walking backwards, where she sat on the edge of his desk behind her.

“Let me get this straight," she said, her tone having shifted into something more relaxed... though no less bemused, “You summoned me – a demon – not to hex someone, not to learn dark arts, not even to cheat in your calculus class..." she looked up at him, her verdant eyes growing tight, “But to teach you something as mundane as calculus?"

“Calculus is mundane to you...?" Leonardo replied... before stiffening up, “I-I mean, yes! Yes, that's it! I... I mean..." he gazed to the side, “I accidentally summoned you. I didn't even believe demons existed until five minutes ago. But..." he looked back, “Lady Fenrir, please, I humbly request with all of my heart that you tutor me in calculus! Y-you see, my final exams are coming up in one week, and if I fail them, I fail the class! And if I fail the class, then it's over..." he shook his head, “My life is over! Um..." he stepped forward, “I was told that you could help me, so... so I guess I summoned you."

“You guess you summoned me...?" Fenrir repeated as she dropped her hand from her face, “Do you even hear yourself? You summoned me – a demon – to tutor you in math?" she shook her head, “Couldn't you just hire a normal tutor?"

“I wish..." he replied, “But I don't have the money to hire a tutor. I was helped by a lady on the way home from my college campus. She said that you could tutor me in calculus. And that... uh... that you didn't accept normal payments..."

“I don't..." Fenrir replied as her hand clutched at the air, “What good will mortal money do me...?"

Swallowing his spit, Leonardo grew quiet as he watched the dark elf pull her hand back and groan into her palm. He could tell she was still baffled by this situation, and was trying to decide on whether or not she should help him. But, hey, she hadn't left yet nor had she killed him, so that had to mean something good, right? He still needed her help however, and he'd do anything to convince her. So, as he had done before, Leonardo swallowed his pride, crawled over towards Fenrir's foot, and gently clutched it.

“Please, Lady Fenrir," he said as he pursed his lips to kiss her foot, “I give you the utmost respect. Please teach me calculus! I... I'll do anything for your wisdom."

“Anything?" the dark elf repeated, “Do you know how dangerous that word is when spoken to a demon?"

Leonardo opened his mouth to speak... but he didn't have a reply. She was right. Saying 'anything' to a demon was just asking for his soul to be dragged down to Hell! But, damn, he was so desperate for help, that he'd risk such a fate.

Fenrir meanwhile looked down upon him with this dismissive and apathetic gaze. It was less like she was staring at a human being, and more like she was staring at a gnat. To her, he was something small and insignificant. She had every right to immolate him on the spot for his foolishness in summoning a demon, even if it was accidental.

Thankfully for him, Fenrir was not so pointlessly cruel.

“What is your name...?" she asked, causing his face to blank.

“My name...?" he mumbled, “Oh! Right! M-my name! Uh... my name's Leonardo! Leonardo Gracey. But... uh... you can call me 'Leo'. Mostly everyone does."

Fenrir sat there, unflinching and immobile. A couple of times she blinked as if deciphering his name... before sighing and rolling her eyes.

“Either your father was a fan of the arts... or a fan of mutated turtles..."

For a few seconds, Leonardo sat there.

“No comment."

Fenrir rolled her eyes and looked away, wearing an indignant face. If his begging endeared him to her on some level, learning of his name did the opposite. It frightened Leonardo, who sat before her with bated breaths. The dark elf eventually gazed back, shooting him a contemptuous gaze as she pointed at his crotch.

“Are you going to put on clothes...?"

Fenrir looked down. Oh. Right. When she emerged in his apartment, he was just finishing his shower! He had been sitting in front of her with nothing but a towel to cover his manhood!

Leonardo's face turned red as he launched up onto his feet, clinging to his towel for some modicum of protection. Fenrir merely blinked at him... before casually pointing towards his bedroom door. She didn't even need to speak, as the young man smiled in a sheepish manner, before scrambling for his bedroom.

WHAT THE HELL! WHAT THE HELL! WHAT THE HELL! WHAT THE HELL WAS EVEN HAPPENING!?

He summoned a demon! He summoned a fucking demon! A fucking demon was in his home! And she hadn't killed him yet!

As Leonardo dressed himself, he couldn't imagine the outlandish situation he had placed himself in. Demons were real, he had summoned one, and she might – juuuuuust might – teach him fucking calculus!

Ya'know... maybe he should've asked her to help him cheat. It would've made life easier...

But, no, he didn't; of course he didn't. He was going to pass those exams one week from now, and he was going to do it legitimately! Even if summoning a demon may be the most illegitimate thing a person can do!

Putting on jeans and a button up shirt, Leonardo exited his bedroom, thinking he'd see nothing. Maybe Fenrir would have dismissed this as a farce, and returned to whatever realm she emerged from. But no. When he exited his bedroom, she was still in his living room, standing there with her face composed... and his calculus textbook in her hand.

Her green eyes looked through his book, scanning every page she came across. Casually she'd flip from one page to the other, but she'd never remain on one for too long. All of those numbers, all of those equations, all of those complex questions that went over Leonardo's head, she read without flinching. And none of them caused her any undue distress. It was all easy for her.

For a moment, he thought about speaking to her, but he instead stiffened up and grew quiet. His gaze traveled over her body, drinking in Fenrir's voluptuous frame. She had this somewhat slender grace, with these shapely hips, this narrow waist, and this pronounced bust. He wouldn't have noticed all of this... had her clothing that emphasized her superior figure.

He saw so much skin... yet there was still so much hidden.

“Leo..." said Fenrir as she looked at him out of the corner of her eye, “Are you just going to stand there with your mouth agape?"

“Huh!? Ooh... uh... s-sorry..."

Was his mouth really open like that? He hadn't noticed. Now he had gained Lady Fenrir's intense glare as she stared down upon him. Right. Lady Fenrir. He had to make sure to call her that when he spoke to her. He didn't want to piss off the magically powerful dark elf he summoned in his home!

She pulled a giant tentacle out of a portal and forced him to the floor! Who knows what else she could do to him!

Sheepishly, Leo approached Fenrir, fearful of doing something out that would gain her ire. Her intense gaze was strong enough to penetrate the very depths of his being: she could see his every flaw, his every failure. How was he going to stand with her for much longer? Could he stand with her for much longer?

Not really...

“Do you have a desk where we can work?" asked Fenrir.

“Uhhh..."

She shifted herself, her body leaning to the side as she crossed her arms beneath her pronounced chest. Like a bee drawn to honey, his eyes were glued to her illustrious figure, and the way her chest gave that bounce, even with the claw-like brassiere she was wearing. Fuck! Why did he have to summon a bombshell of a dark elf for his tutor, instead of, like, some amorphous, nondescript monster? That would've been easier to talk to!

Good thing he put on some clothes. His towel wouldn't have been able to cover his manhood.

“Leo...?"

“Right!" he shouted back, before coughing and resetting himself, “I mean... right. Uh..."

He turned, facing the desk positioned near the window of his apartment. It was a wooden desk, one of a modest size with a few shelves, a lamppost, and a little divot where he placed his laptop when he felt like working here. Which was almost never. The table was somewhat messy with a bunch of textbooks and other reading material. In all honesty, this desk was more for show than it was for any practical use. If he needed to study, he just sat on his couch, or in his bed, or he studied at the study hall of the college campus! Hell, even the lamppost on his desk hadn't been turned on in the past year.

Did the light bulb even work?

Well, okay. Fenrir asked for a desk, and he had a desk! So he walked over to it, pulled out his chair, then pushed aside all the random assortment of crap he had resting on its surface. Glancing over at Fenrir, he read her slightly curious face and raised eyebrow, coaxing him to sit down in his chair.

“So... uhh..." mumbled Leonardo, “How are we going to do this?"

Sit!

“That's my question..."

Leo's eyes widened. Next to him on the surface of his desk, Fenrir sat down. His gaze traveled over towards her hip, watching as her curvaceous butt flattened against the wooden surface of his desk. The split in her dress exposed the sumptuous flesh of her thigh, which glistened in the light of his apartment. His gaze then traveled up, running along her illustrious and curvy figure, where his eyes fell on her face. She was still composed, still regal and noble while she held his calculus textbook in hand.

Fuck. This was no good. Was she purposefully trying to be so damn sexy? He couldn't pull his eyes off of her! And that caused his cheeks to turn redder and redder. Noticing his flustered face, Fenrir looked down upon Leonardo and tilted her head.

“Is something wrong?" she asked, her tone domineering yet dismissive.

“I uh... I..." Leo replied before taking a deep breath, “Could you... do something about your clothes? You got this whole... queen of the damned thing going on. It's really unsettling."

Fenrir didn't respond. She just looked at him, wearing this emotionless visage. Three times she slowly blinked... before sighing and rolling her eyes in a dismissive manner.

“Ugh... I swear... you mortals grow bolder with each passing century..." Fenrir remarked as she walked out of view.

For a moment, Leo feared the dark elf would leave outright. Had what he said come off as too disrespectful? It certainly sounded blasé and way too casual. Hell, who was he to even ask that of her? She's a fucking demon! Of course her clothes would look like something a sexy necromancer would wear! That was probably normal for her!

Gweeeaaaam!

“Uh...?"

Behind him, a bright light flashed through his apartment. Leo pulled forward and gasped, fearful that he had convinced Fenrir to leave. Instead...

Eeeerk!

Another chair slid up. Leo turned to face it... just in time to see the dark elf sit back down. But she was different.

Gone were her witch clothes. Replacing them was something better... yet worse.

SOOOOOOOOO much worse!

Fenrir wore more contemporary clothing, something not out of place on a teacher in high school. A black skirt sat on her legs, one that hugged her narrow waist close and bent tight over her shapely hips. From beneath her skirt extended garter straps, which themselves were attached to the thigh-high socks she wore. The dark elf was even wearing black heels, unlike the sandals from before.

But this paled in comparison to her chest. Gone was the claw-like brassiere she wore. Replacing it was a pressed, white, button up shirt... a white button up shirt that was unbuttoned. It was unbuttoned to the point that it stopped right below her chest, exposing her shapely bust in all of its glory! Her busty cleavage was open before his eyes, with only her black bra standing between him and seeing her full breasts. But even her bra only drew more attention to her chest, with it lifting and flaunting her chest!

How was it possible for someone to put on more clothes, yet look less clothed at the same time!? Fenrir had changed, transforming from an erotic witch, into the world's sexiest and most domineering teacher!

Leo asked her to change his clothes... but this may be even worse. She was even wearing glasses! Did she need those glasses!? She wasn't wearing any beforehand!

“Okay."

And yet, when Fenrir spoke, it was with the utmost professionalism, lacking any playful flair or sensual edge. That didn't make Leo feel any better however. In fact, her indifferent yet regal manner of speaking only furthered the air of her being this seductive teacher... and that feeling penetrated several spots in his brain.

Shit. Should he ask her to change her clothes again? No, no. That would be the stupidest thing he could do! Fenrir already looked done with him and his earlier request; why would she stick around further? In fact... what was she going to ask of him? Was she planning on getting something out of this? Like, how was he going to pay her for her services? With his soul?

He... didn't want to think about it for much longer.

“Leo..." said Fenrir, causing him to tense in place again, “Grab your materials."

“Right...! Uh... yeah, I-I'll get 'em in a second," he said as he pulled out his notes from school.

It was pretty old-fashioned using things like paper and notes in today's day and age, but it was needed for Prof. Hayes' class. She was a very 'show your work' type of teacher, and no, showing it to her on the screen of your laptop was not good enough.

As Leo flattened his notes on the surface of his desk and even grabbed his scientific calculator, he glanced over towards Fenrir. The dark elf was holding his calculus textbook, while her green eyes leered at him. He could feel the intense glare in her eyes; she was going to be very thorough with him. Perhaps too thorough.

“We will start from the top," said Fenrir as she set her glasses on her face, “Are you ready, Leo?"

“Yeah. Yeah! I'm ready. Let's go!"

…

He was not ready.

Numbers! Nothing but numbers! And parenthesis! And Sines! Cosines! Tangents! And the letters! Oh fuck, we can't forget the fucking letters! They were fucking everywhere!

EVERYWHERE!!!

When Leo started, he pulled out a completely blank composition notebook. He expected to get through a page or two, maybe three, with four being the most and pushing it. But he wasn't four pages in. He wasn't five pages in. He wasn't ten pages in! 39! He was 39 pages into this notebook!

THIIIIRRRRTTTYYYYYY-NIIIIIIIIIINNNEEEEE!!!

That's, like, 19 to 20% of the way through this completely empty notebook! And all of it – all of it! – was due to him being grilled relentlessly by the dark elf next to him!

Fenrir was ruthless. While she sounded indifferent, she spared him no quarter. Anytime he made a mistake, she made sure he went through it with a fine-tooth comb. It wasn't enough for him to be wrong, he had to know why he was wrong. A bit difficult really, because he didn't know what made something right in the first place!

Hours had gone by. When he arrived home, it was, what? Just a little past 7 PM? The sun had started to set not too long before he had arrived home. But it had been four hours since then. Now the sun was gone, replaced with the black void of a city night. There were no stars in the skies, but who needs them when the stars of the buildings around them were bright enough to shimmer like a diamond? Just ignore all of that light radiation...

“Aaaannnd... there..." said Leonardo, his tone drained as he leaned back in his chair, “How about this, Lady Fenrir? Does this look good?"

He looked over his shoulder, gazing towards the distance. The dark elf was standing near his kitchen counter, looking at the photos of his family he had placed upon them. When he called out to her, her ears twitched and she turned to face him, shooting him a skeptical gaze. Not that he could blame her: he had gotten almost all the problems wrong so far on his first attempt of answering them.

Walking over, Fenrir's hips swayed seductively as her green eyes locked upon his face. Leonardo shrunk slightly beneath her stare, even swallowed his spit as she drew in close. Hanging above him, the dark elf's eyes began to ruthlessly scrutinize the bevy of notes he had written during their tutoring session. That included the equation he had been tasked with solving.

?4x cos(2 – 3x) dx.

Goodness fucking gracious, just looking at this equation was enough to make Leonardo's head hurt.

But he stayed strong, or, well, as strong as he could be when under the demoness' intense gaze. He was resting back on his chair, while Fenrir began leaning over top of it. When he looked up... he saw her perfect breasts hang above him. An intense red blush appeared on his cheeks as he gazed at their perfect curvature, their perfect size, their perfect shape. Even the way they raised with her breathing was perfect! And all of it was contained in that erotic black bra.

“Aah. Let's see..." said Fenrir as she swung around to Leonardo's side.

One would think he'd feel freed with her breasts no longer hanging above his head. One would be wrong. As Fenrir sat next to him, she reached out and grabbed his pencil and eraser, where she leaned over his desk. Pushing up her glasses with her other hand, she checked over his math work, humming to herself as she read through all of his notes.

And Leonardo watched her.

He was trying. Oh heavens he was trying! But he just could not pull his gaze away from the dark elf next to him! His blue eyes shamelessly traveled along her body, running over her hips, the curve of her butt, and the heft of her bosom. Seeing it all painted his cheeks redder and redder... and caused a stiffening in his pants.

Fenrir was so fucking flawless. She moved with this casual sensuality to her, one that he swore was purposeful. The movement of her pencil, the way she settled her glasses on her face, how her chest raised and lowered along with her breathing; were all demons like this, or was she one of a kind? Fuck. He could understand now why demons were so damn persuasive.

“?4x cos(2 – 3x) dx," said Fenrir, snapping Leonardo from his lecherous gaze, “Equals... -4/3x sin(2 – 3x) + 4/9 cos(2 – 3x) + c."

“Is... that the right answer...?" he asked, causing her to look at him.

“Why don't you see for yourself?"

Leonardo's eyes snapped over, gazing upon the notes he had written. Before, Fenrir had created a bunch of annotated notes, detailing his thought process, and how utterly wrong he was. But this time, there was nothing. His equation was clear, even if to a normal person it would look like a jumbled mess. But to Fenrir...

“I...? I did it...?" he asked as he looked at her, seeing an honest smile sit on her face.

“Yes, Leo. You did it."

An exasperated groan left Leo's lips and he fell back in his chair. It was as if his muscles were instantly reduced to mush, making him sink into his seat like a pile of flesh. He was so terrified he had gotten this equation wrong, forcing him to go back and understand why he was wrong. However...

“Now tell me..." said Fenrir, making him look over, “Why are you right?"

His face turned blank.

“Shit..."

Another groan left Leo's lips, making the dark elf snicker devilishly. She may have been helping him, but he was still being tortured.

“Okay! Uuhhh...!" he mumbled as he looked back at his notes, “I solved this one correctly – unlike the last eight equations – by successfully integrating the dv into v, which itself was... uh... -1/3 sin(2 – 3x)," he paused and looked over, “That's... right, right? Because... I kept failing to compute v before...? Right?"

He looked over at Fenrir, expecting him to berate him. Instead, he saw that smile on her lips. Those shapely lips. The way they bent back and curled, and the subtle glow in her emerald eyes, both sent a rush of reassurance through his body... as well as something else. For all the dark elf's domineering presence and demonic power, there was something undeniably erotic about her. He had been grappling with these feelings all throughout their tutor session! And with her sexy school teacher fit, that feeling grew.

Maybe one of the reasons why he couldn't think so well was because blood was rushing to a different part of his body...

“Correct, Leo," said Fenrir as she nodded, “You successfully computed v, whereas you usually skip over that step and fumble over the Cosine and Sine. However, I still recommend you solve a few more equations so the steps will be grounded into your head."

More equations? Just thinking about it made Leo slump further into his chair, this groan of defeat leaving his lips. He had already been at it all night long! Did he really need to do more?

Yes. Math is cruel and unfeeling. It only cares about correct answers, and nothing else.

But Fenrir stood up, causing Leo to look up at her. Placing her hands on her hips, she swayed her body from side to side like she was performing stretches... which caused her chest to bounce up and down erotically.

“But..." she said, “More equations will be saved for a later date," her green eyes then slid over, “It is late, you have classes tomorrow morning, and I have duties to attend to in my own realm. So for now, I say this tutoring session is adjourned."

“Oh thank God..." Leo groaned... only for his face to turn blank, “Wait... maybe that's the wrong choice of words..."

He looked over, a sheepish grin adorning his lips as he stared up at Fenrir. She looked back, this coy chuckle leaving her lips as gave an amused smile.

Palming his face, Leo felt joy knowing that they were finally finished and he could get some sleep... after he ate that is, because he still had yet to have dinner! He should've bought something on the way home, but whatever.

However...

Now that they were done, that led to another question: What payment did Fenrir require? She wasn't going to teach him for free, was she? Sure, tutoring was beneath a demon – not to mention a demon as powerful as her – but he highly doubted she was going to be charitable about the situation. Demons always get their payment... it only mattered what that payment was.

“Leonardo..." she said.

When his full name left her lips, a cold chill ran down his spine. This was it, this was the moment she reaps his soul, isn't it? And for what? So he could torture himself with calculus equations all night long? That's one terrible way to go!

And yet, Leo took in a deep breath. Whatever his fate may be, he was going to face it with dignity... for now, anyway. The moment she started dragging him, he was going to start kicking and screaming!

“Lady Fenrir..." he said as he stood up to face her, “I guess... this is... uh... this is the moment where you steal my soul, isn't it?"

Fenrir's smile faded, replaced with a cold and indifferent look.

“Tell me, Leo," she said, her stern voice causing him to lock up, “What possible worth could I find in the soul of a man who cannot do math? It would not benefit me in the slightest."

“Ouch..." he replied whilst sheepishly scratching the back of his head, “I guess you're right... uh..." he looked back, “So... that means you won't steal my soul?"

“I never said that," Fenrir replied, “I said that I have no need for your soul. There are plenty of demons around me who'd love to have the soul of a strapping young man such as yourself. I won't take it though... so long as you behave yourself."

“Um... uh... r-right..."

Hearing that sent another cold shudder down Leo's spine. Where did Fenrir say she hailed from again? Mordredus, right? That's the place she said? Wait... wasn't that also the name of the road he passes almost all the time? And that's where he met Hasshaku, which led to this happening in the first place! Just how deep did this rabbit hole go!?

Actually... he didn't want to know. It was probably best if he stayed naive.

“So... uh... if... you don't want my soul..." he shrugged his shoulders, “Then... what do you want from me?"

Fenrir looked at him, her hand raised up as she settled her glasses on his face. Her sudden silence sent another rush of cold down his body; what was she going to ask for? Gold? Blood? His eternal servitude?

No...

Fenrir raised her hand and placed it on his chest, causing Leo to stiffen up. He opened his mouth to speak... but she casually pushed him back, forcing him into the chair behind him. Sitting into it, he looked up at her with his mouth agape, watching as the dark elf stroked her hand through the air... causing a riding crop to appear from nothing.

It was long, the handle black, and the whip itself brown, being made of some leather material. When he saw it, Leo's blood began to pump and he grew confused... as well as unbelievably aroused. And he grew only more aroused when Fenrir drew her riding crop forward, and began teasing it along his cheek.

“Leonardo," she said, “I want your sperm."

Silence...

…

…

“WHAT!?"

Leo's eyes swelled! Did he hear what he thought he heard! Because it sounded like he heard something in-fucking-sane! His sperm!? No! No way! No way! His horny mind must have been playing tricks on him, because there's no way he heard her say what he thought she said!

But Fenrir said it. And when he looked at her, she didn't flinch. Her face remained in that indifferent scowl as her green eyes bared down upon him. But as she teased her riding crop along his cheek and towards his nose, he watched her lips curl into a devilish smile, and her eyes grow sharper.

“You sound surprised, Leo," said the dark elf in a sarcastic manner, “Is something the matter?"

“Gagh!? I...! Wh...!? One thing I...! WHAT!? What possible need could you have for my... gh... sperm...?"

“You mortals... always asking questions," said Fenrir as she crossed an arm beneath her chest, “Listen, Leo. As I told you before, I am the Grand Mage of the Mordredus Wizard Court. As such, it is my duty to perform research for my kingdom in the ways of the dark arts. I take this duty very, very seriously. Being a powerful witch such as myself, it is imperative to have the correct ingredients when it comes to my spells and concoctions."

“In... ingredients...?" he muttered, “Wait..." his head then tilted to the side, “Do you mean my cum...?"

“Well... kufu... that's one way to put it," said Fenrir as she pulled her riding crop back and began to bend it, “The sperm of mortal men is very potent, and is a key component to a wide number of spells. Unfortunately, being a demon and living among demons, mortal men are hard to come by, so it makes collecting their sperm difficult. So, that is what I demand from you as recompense for my tutelage."

This was crazy. Yes, somehow even crazier than SUMMONING A DEMON and then having said demon HELP HIM WITH HIS CALCULUS STUDIES! After all they had done today, all the numbers, and the massive headache he suffered from it all, Fenrir wanted his cum!? What the hell!? Had he stepped into a porno video or something!?

Leonardo may have been frazzled by her request... but his body sure as hell wasn't! Ever honest – even when he didn't want it to be – he felt blood and life start to pump straight to his loins. It wasn't too difficult; Fenrir had been turning him on throughout their whole session! Her asking for his cum was just the last barrier keeping his lusts in check.

Leo looked down, staring at his crotch... where he saw the lump between his legs throb with need. Cheeks turning red, he looked back up at the dark elf above him. Her lips had shifted, turning from that smile into a mischievous grin.

“Well?" she said whilst bending her riding crop, “I'm waiting, Leo! Kufufufufu! Unless you want me to summon Princeton again?"

“P-Princeton...? Who's that?"

“Kufufufufu! Princeton is the name of my kraken," Fenrir answered, “He was the cutie whose tentacle was pinning you to the ground earlier! He's also a girl's best friend..." she tilted her head at him, “Do you want him to be your best friend as well?"

There was so much to unpack with her implications, that Leo's brain short circuited for a second or two. Look, he was an adventurous kind of guy... but not that adventurous!

His cheeks turning redder, he reached down where he thumbed at his pants momentarily. Occasionally, he'd steal glances at Fenrir, who'd snicker as her emerald eyes gazed into his blue ones. She didn't say a word; she didn't need to say a word. The power she had over him was overwhelming without need for commands.

Leo may have hesitated, but that didn't mean he stopped. Unbuttoning and then unzipping his pants, he slowly pulled them down – his underwear too – causing that lump of his to grow and grow and grow until--

Fwip!

“Oh my~"

Extending from between Leo's legs, was his cock. His long, thick cock to be exact. It stood between his legs like a mighty spire, with veins racing down its sides, a bulbous red head, and a hefty pair of balls to boot. All on its own it twitched... and brought a gleam to Fenrir's eyes.

“Well, well, well," said the dark elf as she crossed her arms beneath her chest, “To think you were packing something so dangerous between your legs, Leo. Kufufufufu! I am impressed."

“Ugh... even now you sound like a teacher..." Leo mumbled as his eyes gazed to the side, “So... right... you want my cum, right? So...? What are you going to do? Pull it out of my balls or something?" Crouch, “Huh...?"

Leo gazed down, staring past his cock towards Fenrir's face. The dark elf had squatted down before his member, her pointed nose just a few inches away from his member. Despite being face to face with his cock, she had her fingers on her chin in a thoughtful pose, while her green eyes looked it up and down.

“A superb length," she commented, “Pronounced veins. Hm... quite the sizable scrotum as well. Kufufufufu~! You remind me of..."

But Fenrir did not finish her words. Instead she pulled her hand up, and placed it on the underside of Leo's cock. He tensed up as he felt the smooth and flawless palm of his demonic tutor touch him directly. Without hesitation or shame, the dark elf began stroking her fingers along his length, guiding it from the glands down to the hilt and back again.

“Aah...! Haaha...! Hggnn...!" Leo panted, his toes and hands curling, “What the... fuck is going on…? Aaah..."

“Oh... I'm just about to gain my compensation for teaching you," Fenrir answered... as if she wasn't currently stroking his dick, “This should be a dream come true for the likes of you. You get to expose your obscene penis before a woman like me. Kufufufufu! There are demons who would kill to be in your position~"

“That's... ggah... that's supposed to make me feel better?" Touch! “Aah!?"

Leo's eyes swelled and he looked down. Upon the side of his cock, Fenrir began brushing her riding crop slowly along his shaft. His dick throbbed and twitched beneath the erotic leather of her whip, feeling the edge of it travel down his pulsating veins. Shameless, shuddering groans began leaving his lips, shifting into a sharp gasp when she teased the bottom of his glands.

And Fenrir drank it all in.

The dark elf wore that devilish grin with pride as her green eyes looked up towards Leo's face. Every twitch, every buck, every throb, she indulged in it all with an erotic joy. The way his cock pulsated caused precum to ooze from the tip, while his tightening balls drew closer and closer.

On one side he had Fenrir's riding crop, sliding along his dick. On the other side he had her fingers, dancing and traveling upon him from hilt to tip. Both pleased him beyond approach, with talented touches that knew years, no, centuries of pleasure.

Leonardo was far from a virgin. Sure, he's no playboy, but he's not prude either. He knows the company of others very well in his time. But that meant nothing compared to Fenrir. Even through the touches of her hand alone, he knew she could make him cum on the spot.

If not use her magic to force the same event.

Damn. Leo felt so small beneath her. Sure, it was Fenrir crouching next to him – her face to his cock – but it was she who held all the power. The brushing of her whip, the stroking of her fingers, the leather, the flesh; it all made his cock throb with an almost frenetic need. And right when he thought she'd finally take the plunge to make him cum...

“Aah~"

“Gughh...!?"

Fenrir pulled her hands away, leaving his cock standing on its own. Leo gasped upon being freed, his body dropping into the chair, while his blue eyes gazed towards the dark elf's smirking face. Why had she stopped? Well...

“Your turn," said Fenrir as she stood up before him, “Masturbate. Give me your sperm, Leo."

“Gggh...!"

Her matter of fact way of speaking mixed with her naturally sensual and beautiful voice. When she said something as strange as 'Give me your sperm', it didn't make him cringe or pale with fear, but it made his body so fucking hot! Fenrir owned her words! And in this moment, she owned him.

Leo looked down towards his dick, watching it throb before him. He was so hard and so horny, that his length arched upwards slightly, as more precum oozed from the tip. While he was hesitant at first, he slowly reached down, wrapping his hand around his dick. When he usually masturbated, he liked to have a napkin with him. But right now, his mind was so addled with lust, he didn't even think about stopping.

Mouth agape, Leo began thrusting his palm up and down his dick. His speed was quick, having lost himself to his desires, and refusing to let up. Each push caused his balls to jiggle and jump between his legs, while more and more precum oozed from the tip. He was so forceful! So lively! So needy! And that made Fenrir's eyes glow.

“Kufufufufufufu~!"

Her erotic laugh danced in his ears, making his body burn all the hotter. With an almost desperate look in his eyes, he stared up towards Fenrir. The dark elf's green eyes were locked upon him, and she wore this devilish smirk on her lips. Her body was also leaning over slightly... causing her breasts to appear more pronounced in that domineering teacher's outfit she wore. Shamelessly, Leo stared down her cleavage, imagining all the sordid and lascivious things he'd do to her if he got the chance.

First? He'd just bury his head in her breasts. He'd motorboat her tits, hug her tits, kiss her tits, suck on her tits, and squeeze against them for as long and as hard as he could.

But why stop there? As if reading his mind and seeing all the lewd things he wanted to do to her, Fenrir suddenly raised her foot, and placed it down between his legs. Leo's eyes grew wide as the perfect foot of his demonic tutor sat just a few centimeters away from his cock and balls; all for his viewing pleasure.

The perfect shape of her long legs. The plumpness of her shapely thighs. The lewd teacher's uniform that accented her erotic figure and domineering grace. Every aspect of Fenrir's body was flawless, and it inspired no end of lewd thoughts in Leo's mind.

All the things he'd do to her breasts, he'd do to her legs as well. He'd hug them, kiss them, he'd lick them, he'd squeeze them. He'd shower her legs and her body as a whole in the praise it deserved!

But he couldn't, not now. The dark elf had only ordered him to pleasure himself, and like some lowly servant, he obeyed. Was she using some magic on him? Or was he just that desperate for her approval? Maybe a part of him knew how stupid it was to go against a demon.

Regardless of the 'whys', nothing could change the fact that he obeyed her, and masturbated furiously. The palm of his hand ran along the veins of his cock, while his other hand sat on his thigh. His cock – sputtering and throbbing – grew tighter and hotter within his grasp. He could feel it; his limit was fast approaching! Screwing shut his eyes and gritting his teeth, Leo thrusted his hand down one last time, and--

“GUH!?"

SPURT! SPLORT! SPUUURRT!

He... he couldn't remember the last time he came so hard...

Thick, virile, male jizz came launching out of his dick, shooting high like a volcano erupting. Spraying sperm stained the air, spreading outwards towards Fenrir. It was pearly. It was white. It was hot. It was fragrant. It was potent.

And Fenrir caught it all.

From the hand of the dark elf, she produced a magical container. It was mauve in color yet translucent, allowing Leo to see his sperm settle within. There was a copious amount – far greater than usual for him – and it all collected at the bottom.

A wicked grin adorning her lips, Fenrir forced the sphere of magic to condense and transform into a purple bottle with a plugged cork. Raising said bottle up to her face, the dark elf swiveled it from left to right, causing his spunk to swirl within. She then pulled the cork off the top and dipped her finger inside, tracking some of his cum on her digit. His eyes still dazed and mouth slightly agape, Leo watched as the demoness pulled her cum-covered finger up to her lips, and--

“Lick~ Lick~ Lick~ Hm... not bad," said Fenrir as she turned to face him, “Quite virile of you, Leo. Rich in fertility and vitality."

“Um... th-thank you...?" he replied, confused by what he should say.

“Kufufufufu~ Indeed," she said as her eyes swept back over towards the bottle containing his cum, “I believe this is more than sufficient payment for today's tutelage. However..." she looked back at him, “Your final exam is in one week, correct? Then for the next week before the day of your exams, I shall visit you upon your return home. We will then continue your tutoring until you are a certified mathematician."

“A...? A mathematician...?" he mumbled as he slowly pulled up his pants, covering himself, “Is...? Is that really necessary?"

“Of course it is," she answered, “You want to pass, don't you? And I..." she wiggled that container of cum again, “Need more of this from you. One bottle is good, but it's far below the standards needed for my concoctions. So we shall keep going until either the week's time has elapsed, or I completely drain you of your seed."

Leonardo's face paled upon hearing her words.

Ya'know, he was afraid of Fenrir. He feared she would kill him and drag his soul to Hell, or she'd kill him with calculus and numbers. He didn't think she'd kill him by milking his cock dry.

As he sat there, contemplating her horrifying words, the dark elf stuffed aside her recently-acquired bottle of cum and turned around. Raising her hand, she caused the ground to rumble beneath their feet, making Leonardo pull up. In the open spot before them, those purple flames from before emerged from the ground. They flowed outwards throughout his apartment, causing him to gasp... while Fenrir remained indifferent.

Rising up from the shadowy flames was the same Gothic door the dark elf appeared from. It loomed tall in his room, casting its shadow upon all objects within, while exuding miasma from its seams. Gazing at it, Leo's eyes were wide and his mouth agape, awed by what he was witnessing. After spending the last several hours with Fenrir, seeing her flaunt her magical might reminded him that, yes, she is a demon. And not just a demon; she hails from a completely different world!

“Is this...?" he whispered as he stumbled forward, “Where... where does this lead to...?"

“Daemonium," Fenrir answered, “The realm of demons."

“Dae... monium...?" he repeated before raising an eyebrow, “Wait... not Hell...?"

“Kufufufufu~ Oh Leo..." Turning over, the dark elf placed her hand on his cheek, where she gently brushed her fingers along his face. She stroked him like he was a dog... and like a dog, he melted under her touch, “Do not ask questions when you aren't ready for the answers."

He tilted his head at her, confused by her words... before swallowing his spit and nodding. Right. He couldn't even do calculus on his own; maybe it was best to not ask about the vastness of other realms. His head probably couldn't take it.

Walking to the door, Fenrir opened it up, revealing the void of darkness on the other end. Leo wanted to push forward and see what laid on the other end... but he knew better. Sitting there, he watched as the dark elf positioned herself in front of her door, the shadows within blowing along her body like a strong gust of wind. She then entered inside, closing the door behind her, and separating herself and her realm from Leo.

For a few more seconds that door stood there; a gateway to another world. Biting into his bottom lip, Leo bravely – and stupidly – stood up and approached it. But before he could grab its knob...

Zwoooosh! Grmble! Grmble! Grmble! Grmble!

Those purple flames sprouted from its base once more, and the door began sinking into the floor. Just as quickly as it appeared, the demonic door vanished, returning Leo's apartment to normal. He stood there

Standing there, he pondered if the day's events even happened. Demons were real, and one of them was teaching him calculus. Maybe he should visit his local priest...

Grrrrrrrrrrgggkkh!

After he's had dinner, that is...

…

Tuesday...

Another day, another dollar. Not a lot of dollars, mind you, but better dollars than nothing.

Leonardo Gracey was a college student, one with dreams of becoming a lawman in the near future. But until then, he had to support himself like everyone else. He no longer had his mother and father to buy things for him; he had to fork over the cash himself. That meant working long hours at a local factory. It was a good job... came with a lot of benefits too... but damn was it hell on his feet.

A gust of wind was blowing along Leo's body as he walked down the streets, and the setting sun hung above his head. In his hand he carried a paper bag of food; just a little something he picked up on the way home from work. A greasy burger, equally as greasy fries, some root beer; nothing too special. Damn, was his stomach grumbling however.

As he climbed the stairs up towards his home however, he felt dread befall him. Was he... scared? Yes, in a way... but not for the reasons one would think. He spent all of last night grappling with the realization that demons exist... and who knows what else in those 'realms' Fenrir spoke of. The conclusion he came to was simple: It was best to not think about the vastness of reality. He was just one mortal man, one who wasn't good at calculus. It was probably out of his jurisdiction to ponder reality as he knew it!

But, no. No, no. That's not what had Leo scared. What had Leo scared was knowing that when he stepped through his apartment door, he'd have to endure another night of tutoring.

He was not ready.

Eeeeaaaarrrrrrk...!

“Huh? What the?"

In more ways than one.

Leo thought he'd enter to see his empty apartment. Instead he saw books. Dozens of dozens of books. They were stacked atop one another in these small towers that dotted his home, making it somewhat difficult to navigate around them. Upon closer inspection, he learned that these books were either math books (ugh...) or law books (oh?).

“What the...?" he mumbled, before coming to a stop, “Ah...?"

“Hello, Leo," a voice greeted him.

He turned, his eyes falling on his couch. For laying there, wearing that 'queen of the damned' dress she first sported when he saw her, was--

“Lady Fenrir...?"

She looked up at him, an alluring smile adorning her cheeks as she nonchalantly reclined on his couch. In her hands was one of his thick law books. Was she reading it as she awaited his return? Casually? Who casually reads a textbook?

“You are... already here...?" said Leo as he dropped his backpack upon the couch's edge.

“I did not know you had work today," Fenrir answered as she placed the book she was holding aside, “I arrived at a similar time as yesterday, only to see you had not yet come home. So..." she looked around, “I deigned to make myself comfortable as I awaited your return."

“And 'comfortable' to you is..." he brushed his hand along a nearby book, “Reading a bunch of... gray, thickheaded, boring tomes until your eyes bleed?"

“Kufufufu! These books are nothing compared to the ones I read," she replied whilst rising up from the couch, “The history and knowledge of your word is minuscule to the sheer breadth of information that exists within my kingdom, let alone my realm as a whole. If you think these books are big, try searching through a history book that has infinite pages."

“In... infinite...?" Leo mumbled, before looking aside, “Y-you're right... that... that is pretty big..."

“I feel like I've learned a lot about you after snooping through your perfect effects," said Fenrir, bringing his gaze back over, “You didn't tell me that you were going to a college meant for law, Leo. And a prestigious one at that. Since you went through the trouble of summoning a demon, I assumed you were taking General Studies. But I suppose demons and lawyers often go hand in hand."

“Not a lawyer," Leo replied, “I'm studying to become a defense attorney."

“Ohhhhh! A defense attorney!" the dark elf replied, her face lighting up in genuine awe, “What? Are you a self-righteous type? Do you see yourself as protecting those who cannot properly defend themselves?"

“I... well..." he looked to the side, blushing slightly as he shrugged his shoulders, “I... I guess..." he slowly swept his eyes back, “I just don't feel comfortable being someone's weapon to attack someone else. I mean, yeah, defense attorneys and lawyers aren't really that much different... but it feels different to me..." he shrugged his shoulders again, “Gah. But what the hell do I know? I could end up defending some old fart who abuses his power," he tilted his head, “What about you, Lady Fenrir? With a title like that... and... you said you were a Grand Mage, right? Of... uh... Mordredus...? Right?"

“Kufufufufu! I see... so you may not pay attention to math, but you do pay attention to words. I'll be sure to keep that in mind for the future," said Fenrir as she drew in closer, “Yes, I am the Grand Mage of the Mordredus Wizard Court. As I told you before, I perform studies and other endeavors of a scientific and magical kind in order to further the reach of my kingdom, Mordredus."

“Your... kingdom..." he replied, “With that crown on your door whenever you appear... do you... rule it?"

Fenrir tilted her head at him.

“No," she answered, “The rulers of Mordredus are family Mordredus, with its current reigning monarch being Queen Iris. She presides over our nation with strength and grace. I have known Queen Iris since I was a child, as we grew up with one another. The crown you see on my door however is my family's crest: the Void Crown of Vanagandr. It is where my family derives some of our boundless magical talent from. But..." she stood up from the couch, “That is not important now."

Gweeeaaaam!

Around Fenrir's body, a bright light emerged, causing Leo to wince and pull back. When the light subsided, gone was the dark elf's dress, replaced with that domineering teacher's outfit from before. She was even holding that riding crop in hand again and began bending it tauntingly.

“It's time for us to get to work, Leo," she said whilst facing him.

“Rrriiiiiiigght..." he mumbled... before lifting his bag of food, “Can I... eat dinner first...?"

…

“No, no, no no, no! The derivative of x = y2 – 2 is not dx/dy = -2y! The 2y is not negative! It is positive!"

“Gggghh!"

Fenrir was hot. She was sexy. She was alluring. She was intelligent.

But she was also strict. She was oppressive. She was overbearing. And dammit, she could be cruel.

Bullets of sweat poured down Leo's face as the domineering dark elf loomed overhead behind her. Green eyes sharp like a hawk, she peered down upon him and his paltry math work, bending her riding crop. He could hear the tensing of the leather, with each 'Creeeeeaaaaaaak!' sending shudders down his spine. Fuck. This was too much. He thought Prof. Hayes was a strict teacher, but Fenrir blew her out of the water!

The voluptuous shadow of the dark elf fell upon him, filling his mind with thoughts both lewd yet horrified. Horrilewd? Lewdified? Whatever you wanted to call it, one thing was clear; he couldn't focus. All he saw were numbers and Fenrir's sexy body!

“Do you understand why the answer should be dx/dy = 2y, Leo?" asked Fenrir as she raised her foot and placed it to the back of his chair, “It's important that you do. If you fail to understand your mistakes, you'll fail to solve the rest of the equations."

Leo groaned from her words, annoyed by them.. but understanding she was right. As much as he wanted to talk back to her, he knew how stupid that would be. Even if she wasn't a demon, you don't want to piss off the person who's helping you with a subject you struggle in.

So he closed his eyes and took a deep breath as he settled his nerves. Yes. Right. Why was he wrong?

Because of Fenrir's tits.

As shameless as it was to say, he couldn't focus well with the dark elf constantly looming above him. Whether she stood behind him, stood next to him, or even sat beside him, her presence carried with it her erotic figure. The shadow of her figure was painted against him, exposing the curve of her breasts and butt. Shit! How could he focus when she was constantly swaying left and right behind him?

Unfortunately, he doubted blaming his failure on her breasts would be a valid answer. So he had to focus down, and really look at his equations. Yes. Look at it. Look at it. Look at it. And, no! Don't leer at the reflection of Fenrir's breasts on the surface of his laptop!

Shit! He was already doing it!

“Leonardo..." the dark elf growled, her alluring voice rumbling with this chilling aura, “Why. Were. You. Wrong?"

“B-because...!" he shouted out, before calming down and taking a deep breath, “Because... haaah... the original function was... y equals the square root of x + 2. While I computed that into x = y2 – 2, the minus 2 does not make the derivative into -2y. Like the original function, it should be... just 2y... ah..."

Leo turned, facing Fenrir. The dark elf was still standing behind him, her arms crossed as she gripped tight upon the handle of her riding crop. Those green eyes of hers were intense, strong enough to penetrate his soul, and causing him to swallow his spit. But he didn't look away, couldn't look away as he awaited her response.

“Hmm..." the demoness muttered as she tipped her glasses up on her face, “Haah... you may stumble, Leo... but you do not fall. You are correct."

A sigh of relief left his lips and he slumped back in his chair, feeling as if a powerful weight was pulled off his shoulders. Despite his mind being filled with thoughts of Fenrir's flawless figure, he somehow focused long enough to look at his notes, and understand why he was wrong. That was something he needed to remember in the future when the exam came.

For now however...

“I believe that was more than sufficient for today," said Fenrir, making Leo perk back up, “So let us adjourn today's session."

“Ah... great," he said as a hapless smile adorned his lips, “All of this math is really tiring me out... I feel so... uh..."

Cutting himself off, he realized that if their session today was over, then that meant Fenrir was going to need her payment. And if she was expecting her payment, then that meant he needed to perform.

Leo turned, facing Fenrir. Resting on the dark elf's lips was that devilish smirk. It told him everything he needed to know, causing his cheeks to turn red.

“Aaah... i-is this really necessary," Leo said in a somewhat standoffish manner as he began fiddling with his pants, “Isn't there another way to get my cum without making me beat off in front of you?"

“Kufufufufu~ There are other ways," Fenrir answered with a flirty wink, “But this is far more fun, wouldn't you agree?"

Well... Leo really couldn't argue. Despite how embarrassed he was, nothing actually stopped him from moving. He undid his jeans and even removed his shirt, slightly undressing before his demonic tutor. She meanwhile chortled softly, while her green eyes looked him up and down.

“You're so eager today, Leo," Fenrir commented, causing him to give an annoyed huff.

“I-I'm not that eager..." he lied as he pulled down his pants, “I'm just... t-trying to get this over with...!"

Fwip!

He may have been abrasive with his words, but his body was anything but. When his pants and underwear were pulled down, his long and thick cock bounced to attention, having gained its maximum length and rigidity. The pulsating veins, the swaying balls, the throbbing dome, even the oozing precum; his manhood was filled with the relentless vigor of a virile young man.

“I can't believe I'm doing this again..." Leo offhandedly remarked, while Fenrir approached him.

“Oh, don't sound like that," she coyly teased, “It is just you and I in this chamber; there's nothing to be embarrassed about! Kufufufufu! Besides... you were quite shameless with your ogling mere moments ago."

“My... ogling...?" he repeated whilst looking away in an attempt to save face.

“Don't be so bashful now, Leo. It's not like you've been shy in your lecherous leers during our time together," said Fenrir as she began teasing the edge of her riding crop along his chin, “Every time your eyes stroked along my chest, or upon my thighs, or over my face... kufufufu~ I felt it all~"

Leo gritted his teeth, trying to hide his shameless arousal... and failing to do so. Even if he was able to tell a convincing lie, how could he hide his throbbing erection? Yeah, he couldn't!

“Alright," he said as he moved his hand towards his dick, “I guess... I'll just start beating for you."

“Actually..." said Fenrir, her devilish grin growing in size as she tugged on her riding crop, “I have a better idea," she pointed forward, “Turn around. Put your hands on the desk... and push out your romp~"

Leo's face paled upon hearing this. She wanted him to... put his hands on his desk and push out his ass? There were a hundred ways these would go, and he was sure a majority of them ended with him being sodomized.

That was not something he wanted to experience!

So why did he turn around? Why did he place his hands on the desk? Why did he push out his ass? Because he was a pathetic, horny, fucking idiot, that's why! A fucking demon was telling him to turn around! Didn't he know better!?

Apparently not...

Leo grumbled to himself, stewing in place while Fenrir's snickers filled the air behind him. Drawing over her riding crop, she began teasing it along his butt, causing him to shudder.

“Feel's scary, doesn't it?" asked the dark elf as the leather of her whip slid along his body, “Not knowing what's going to happen. Feeling powerless to stop it. And yet, feeling turned on by it nonetheless. It's exhilarating, isn't it? Kufufufu~ I know that feeling all too well."

“The way you sound...? What are you..." mumbled Leo, “Some kind of dominatrix or something?"

He couldn't see it, but Fenrir nodded.

“Yes~" she answered, “But I'm not like you mortals. Even the most extreme dominatrix would pale in comparison to one such as I. Kufufufufu~ the things I could do to you, the things I could make you do, and the things I would do for you, would make your head spin."

“I... uh... hmm..."

Again, Leo's face turned red, his mind racing with a flurry of thoughts. She wasn't just a dominatrix, she was a demon! Who knows the level of depravity she indulges in on the regular! Even while speaking with this cool and refined tongue, there was this unmistakable danger to Fenrir... and that only added to her allure.

Was Leo into Domination and Submission? No, not really. Sure, he got turned on occasionally by the thought of bondage, but what guy doesn't? Seeing someone strung up was erotic on occasion... but that didn't mean he was racing to try it himself. It was just a thing, ya'know? Like a myriad of kinky sights one sees when pursuing the internet at night.

But Fenrir was making him rethink that. As the smooth leather of her riding crop teased along his hips and butt, he felt his cock start to throb. He gritted his teeth too, while mentally cursing himself for how obedient he was. The dark elf must have sensed his slight agitation, for she began to chuckle... before placing her hand on the small of his back.

“Calm down, Leo," she said in a taunting manner, “I promise, I won't do anything you'd dislike."

“What's a promise to a demon?" he countered, to which Fenrir giggled.

“Kufufufufu~ touche~ Chu~!"

“Gah!?"

Did she... just kiss his butt!? Yes! Yes she did!

Pursing her lips, Fenrir placed them to the curve of Leo's butt. He jolted upright in place, astonished, but she didn't mind. She didn't even flinch. Still wearing a smile on her alluring lips, the dark elf planted kiss after kiss on his butt, while her flawless hand gently brushed along his hip and leg. Her touch was soothing, causing him to melt against the surface of his desk, even while he wore an embarrassed and abrasive face.

“This is... bleh..." he mumbled, making Fenrir giggle more.

He tried so hard to remain indignant, but nothing could stop his body from getting hotter and hotter... or his cock from getting harder and harder. Looking down, the dark elf's emerald eyes locked on Leo's length, where her teasing face shifted into something more lascivious. She leered at his dick, smirked, even licked her lips, all while taking note of his pulsing veins and throbbing shaft.

“Such a thick boy~" she whispered as her hand traveled over, touching his cock.

“Aaah..."

Closing his eyes and clenching his teeth, Leo jolted upright as Fenrir's hand touched his cock directly. Her fingers were slender and immaculate, and they touched him with precision. He felt her guide her digits along the veins, tracing them like a highway of pleasure. From the hilt, along the shaft and to the tip, not one area of his length was left unexplored by her touch. And with each stroke, Leo's body would shudder, which in turn made his cock throb even harder.

Precum was flung about from his pulsing cock, tracking upon his desk and falling on the floor. Shit... he had never produced so much in his life! Then again, he's never been pleasured by a woman as talented and as sexy as Fenrir before.

Grip!

“Hrrrgkh!?"

Without warning, the dark elf wrapped her hand around the shaft of his cock, gripping him tight. Leo's eyes swelled and his mouth split open, letting out a gasp as he looked over his shoulders. Even over his butt, he could see her grin back at him... while the grip around his cock grew tighter.

“Just grin and bare it, Leo," she ordered... though her tone was oddly reassuring. Well, he may not grin... but he would bear it...

Leo felt the smoothness of Fenrir's palm, and the gripping strength of her fingers. She knew how to handle a dick. She knew how to please a dick. Despite his impressive size and girth, the dark elf wasn't shy in the least bit of stroking her hands along his shaft. She squeezed it from the bottom down to the tip, as if trying to pull the cum straight from his balls.

His balls. His tight balls. How round and plump they were. He couldn't remember a time where he felt his scrotum pain him so much. It was like his sack was churning with cum!

And Fenrir looked up at his balls, watching it jiggle as sweat oozed down their form. With one hand still stroking and milking his cock, her other hand fell upon his balls, gripping them. The firm hold on his sensitive sack again caused Leo to tense up, and coaxed a groan from his lips. But the dark elf did not stop.

With one hand fondling his balls and the other hand stroking his cock, Fenrir milked his dick like she was milking a cow. Her gropes and kneads promoted blood flow, causing his veins to pulse even more. She was giving him the handjob of a lifetime, and he could feel his cock start to tighten! It stiffened in his hold, while she brought her hands down to tease upon his glands.

Keeping him simmering with pleasure, her other hand left his balls, where she closed her palm... before opening it to reveal a bottle. It was a similar bottle to the one she contained his cum last time. Was it the same bottle? Did it matter?

Not really.

Lifting the bottle's top up to the tip of his cock, Fenrir lined everything up. All Leo needed to do was cum, and his essence would be contained within this jar. So with a wicked grin on her lips, Fenrir started stroking his cock even faster, even harder. The gripping and squeezing made Leo shudder, and caused him to part his legs wider to strengthen his hold. His nails even started scratching upon the surface of his desk, as the pleasure mounted more and more. All it took was one last...

SQUEEEZEE!!!

“GAH!?"

SPLORT! SPURT! SPLUURRRRRT!

And Leo was cumming!

From the tip of his dick, he launched rope after rope of pearly-white seed into Fenrir's awaiting bottle. His cum was thick and creamy, flowing into the translucent vessel and collecting at the bottom. How many blasts of seed did he launch? He wasn't counting! He just knew it felt so fucking good. A wave of relaxing pleasure washed over his body, while Fenrir continued squeezing his cock.

She drew out his orgasm, making sure to collect every pint of spunk he could give her. And collect it she did. The dark elf allowed none of it to go to waste, as every bit was contained within her bottle. And when Leo finally stopped cumming...

“Aah...!"

He collapsed slightly against his desk, while Fenrir stood up.

Shaking his bottle of cum from side to side, she shot in an... incredulous look. Was it her, or was there less seed in here than there was yesterday? It wasn't a lot, but it was certainly noticeable for someone like her.

“Hmmmm..." he audibly mumbled, making Leo tense up.

“Is.. aah...! Is something wrong?" he said through slight pants.

“Yes," she replied, “Something is wrong..." her green eyes then looked over towards his face, shooting him a glare, “Is something wrong with you, Leonardo? There's less sperm in here than there was yesterday. Did you masturbate sometime today?"

“WHAT!?" he replied, jolting upright like someone shocked him, “N-No! I didn't masturbate! When would I do that? At fucking work!?" he shook his head, blushing furiously as he glanced to the side, “L-look, I can't do anything about how much cum I make! I'm not a fucking cum factory! I...!" he shrugged his shoulders, “I dunno..."

“Hmmmm..."

One week. They had one week's time to spend together. That was plenty of time to milk his cock for all the cum stored in his balls, and make no mistakes, she fully planned on doing so. However, now she was beginning to wonder if that would be enough.

Accursed mortal biology. No matter how much cum she'd like, and no matter how willing Leo was to give it to her, she was restricted by the limits of his body. She could milk him all day everyday, and she'd get nothing but diminishing returns! Assuming he lived through it all.

But as annoyed as Fenrir was, she was not defeated. Quite the opposite, really; the dark elf had an idea of how she could... help Leo out with his little 'limitation'.

As he scrambled to pull his pants up, the voluptuous demoness turned around, facing her back towards him. Eyebrow raised, he watched as her hands scrambled out of view, while hearing a variety of 'Clicks!' and 'Clanks!' just what was she doing?

“Um...? Fenrir..."

“Here," she answered whilst turning to face him.

In her hand rested a bottle. Not a bottle of his cum – she had already stuffed that aside. No, this was a bottle of something else; a bottle of a strange pink liquid. It shimmered when the light from above struck it, glowing like glitter on a stripper's body. Not that Leo would know anything about that, of course!

“What...? What is this...?" he muttered as he stared at the bottle.

“This? You are going to drink this," Fenrir answered.

For several moments, Leo stared at her, his expression slightly tense. It took his mind several moments to parse the information given – ordered – to him, and when it did...

“What!?"

Fenrir didn't respond, instead letting her smile spread wider on her lips. Raising the bottle of... whatever it is, she shook it in his face, like dangling keys in front of a child. Leo pulled away from it... but his curiosities led him to curl his hands beneath the bottle, letting her drop it into his palms.

“What is this...?" he asked as he gazed upon the shimmering pink substance.

“This is... huh... oh... how would I explain it...?" Fenrir asked herself, “I suppose I could tell you it's name... though it wouldn't matter much to you, since it does not exist on the mortal plain," she leaned in whilst adjusting her glasses, “This, Leo, is known as Piram Elixir. It is created from a variety of ingredients – incubus extract and dragon eggs being the most important."

“I'm sorry, WHAT!? Incubus extract!? Dragon eggs!? Wh-what!? Dragons exist!?"

“When ingested, Piram Elixir grants several boons, the key one for us being an increase in the production of semen," Fenrir continued on, ignoring him, “So... as I said before, you are going to drink this."

Leo's face visibly cringed at her order, his blue eyes looking over towards her and her smiling face. Such a cruel elf; she indulged in his suffering, took pleasure in it. Sure, she may not be whipping him, or flogging him, or spanking him, but she caused him pain nonetheless.

Did Leo think about saying 'no'? Of course he did! But what good would that do him? If he said 'no' to her order, he'd risk running the dark elf away. Or worse; she forcibly milked him of all the cum in his balls, and then left him to fail his exams without her tutelage! Assuming of course he survived the relentless milking he'd suffer beforehand.

At least this way, he had the illusion of choice... flimsy though it may be.

Letting out a sigh of defeat, Leo gripped the cork of the bottle, twisted it, and pulled it out with an audible--

Pop!

Sniff sniff... oh... it smelled pretty good. Quite sweet... quite sugary... a bit spicy too... nothing like he feared it would smell like. But what would it taste like? Leo pondered that as he took another glance towards Fenrir, who smiled and nodded at him. Oh well... bottoms up!

“Gulp! Gulp! Gulp! Nbnngghh...!"

“Hm? How does it taste?" asked the dark elf as she placed her hands on her hips.

“Gglaaah... ggh..." Leo mumbled back as he stared down towards the now empty bottle, “It uh... um... it..." he shrugged his shoulders, “It doesn't taste half bad, actually..." he then looked over, “Kinda sweet... a bit sour... huh. I was afraid it would taste like liquid medicine..."

“Good to know," said Fenrir with a wry smirk... before she pulled back and faced the empty spot before her, “Alright... it is time I returned to my domain..."

“W-wait, Lady Fenrir," said Leo as she caused her doorway to emerge from the ground, “Gah... uh... that... um... Piram Elixir you gave me..." he cocked his head, “It's uh... it's okay, right? It's not gonna do anything too weird to me, will it?"

The dark elf didn't answer, instead walking up to her door and grabbing its knob. Twisting and turning it, she opened her door, revealing the dark void on the other end... where she stopped. Slowly, Fenrir looked over her shoulder towards Leo, causing him to lock up as if he was frozen solid. There was a mischievous grin on her lips, and a glow in her green eyes.

“There may be some... unforeseen side effects. It's been a while since I've given Piram Elixir to a mortal~"

“Uh... ggh...? Wh-wha...?"

He didn't get the chance to answer her before she entered through her door. Closing it behind her, she sent a booming 'Thud!' throughout Leo's apartment. Too stunned – and frightened – to move, he stood in place, watching as Fenrir's door sank into the floor, where it eventually vanished.

For several more moments Leo stood there in silence, thinking about how stupid he was to drink that strange elixir. His thoughts soon shifted to his manhood, causing him to look down towards his crotch.

“I... I shouldn't have drank that, should I...?"

…

Wednesday...

No. No he shouldn't have.

Remember going through puberty, and when your penis starts to get hard for seemingly no reason? Maybe you paid too close attention to a girl, or maybe you let your imagination run wild, or maybe nothing happened at all! And yet all of those feelings within you start to swell, mixing with biological changes you don't understand nor can you explain. And all of it – all of it – starts rushing straight to your dick.

You're in the middle of class, and much to your horror, you get an erection. Making matters worse, the teacher calls upon you to read a passage from your textbook. All eyes are on you, and you're desperately trying to hide the hard-on your sporting.

For Leo, this was something he thought he squashed back in high school. He was an adult now; he knew how to handle his body! At least... he did... and then he foolishly drank Fenrir's potion, cursing him with... this!

“Grrgg...! Hggghhnnn! Hrrrk...!"

You know what's bad? Getting an erection in a public space. You know what's worse? Maintaining an erection all throughout the day!

Leo marched down the sidewalk, his grip tight on his backpacks strap, while his teeth were gritted hard. He appeared hot and sweaty, with a red face and a tense expression. Even the way he walked was stiff as his body appeared less like a human, and more like a wind up doll with how wonky he moved.

But could you blame him when his cock absolutely pained him?

Between his legs, sliding down his right pant leg, was the prominent and impressive outline of his bulging cock. It strained against his slacks, long and thick like some writhing snake! Whenever he stood, it seemed to throb! And whenever he sat down, it ached him with how awkward it was! And that's not getting into how he seemed to secrete precum damn near endlessly!

Even his pants tortured him. His cock was so sensitive, that the slightest pressure of his trousers sent bolts of pleasure racing up and down his form. Every ridge, every stitch, every fold; Leo felt all of it relentlessly grind against his manhood from even the slightest of movements! It was like suffering from a handjob all day long!

DAMN!

He was so hard and so embarrassed, he couldn't look anyone in the eye. Normally the class clown, he always had some snarky comment to whatever one of his professors said. But today? Nope. Not a word. He just sat there, stewing in his own torturous pleasure, all while cursing Fenrir under his breath.

He was sure someone had to notice his throbbing dick. Damn. He felt so bad for the people who stood next to him on the metro rides he took today. Gah! It was probably best to not think about it...

Finally – after hours upon hours of torture – Leo had arrived home. He rushed inside, his body a virtual blur as he ran upstairs. All he could think about was wrapping his hand around his cock, and masturbating until all of this pleasure – and pain – left him! He was so quick, that he forgot when he ran through the door...

Crash!

“GACK!?"

He'd collide with towers of books.

Leo fell face first into the floor, groaning with pain as the pointy edges of all these textbooks and tomes jabbed into his body. Shit. He should've told Fenrir to clean up her mess before he left yesterday. Wait... Fenrir...?

“Are you okay, Leo?" a nonchalant yet alluring voice echoed from above.

Pulling his face up from the floor, he gazed up towards his couch. Sitting upon it, wearing her witch dress as she casually read a book, was--

“FENRIR!!!"

“Don't be so loud, Leonardo," the dark elf casually replied whilst turning a page in her book, “You'll bother your neighbors..."

“FUCK THEM!!!" he shouted as he sprang up to his feet, his face angry and cheeks red, “Fenrir! What did you do to me!?"

“Hm? What are you talking about?"

“I'm talking...!" Fwump! “About THIS!!!"

In record time, Leo pulled down his pants and underwear, revealing his dick. It stood tall. No. It stood longer than 'tall'. It was fucking massive! A wickedly thick and impressive cock, one that arched upwards through the air. The veins which were already prominent, now appeared twice as big as before as they raced up and down his length. The doming head of his penis was now wider and redder as well, swelling like a balloon about to burst! And his balls!

His balls...

Leo's balls were big, firm and tight as befitting a fit young man of his age. But now, they had doubled in size. His balls were like two tight tennis balls in how big and large they were! One could see them churn with the semen stored inside, as if begging to be unleashed. It must have pained him!

No, not 'must have'; it did! Leo was in pain!

And Fenrir was pleased.

“Well, well, well," said the dark elf as a fang-flashing grin appeared on her face, “I see my elixir has worked wonders on you."

Putting aside her book, she hopped off the couch and stood before Leo... before crouching down to sit near his throbbing cock. He looked down, his teeth gritted and hands twitching, while the dark elf casually produced a pen with a magical flourish of her hand. Tapping it against the side of his cock...

“Aha!?"

She sent a jolt up through his body. Fuck. His dick was so sensitive, that merely feeling the tip of a pen was enough to cause him excruciating amounts of pleasure. A bullet of precum was even launched out from his dick, with it flying out to strike her face.

Fenrir didn't flinch.

With a casual ease, she traced the tip of her pen along the bulging veins of his enhanced cock, sending further jolts throughout Leo's body. His legs began wobbling, struggling to keep himself upright while desperate groans left his lips. She giggled in response, while her green eyes stared up towards his desperate face.

“Are you okay, Leo?" she asked, her voice filled with taunting venom.

“You know exactly how I feel," he growled through gritted teeth, “You said that the elixir was just supposed to make me cum more! You never said this shit would act like super-charged Viagra!"

“Nuh-uh-uh!" she replied with a cocky wag of her fingers, “I did warn of unforeseen side effects, did I not?"

“Yeah! After I already drank it!" he snapped back, “What good does that do me!?" he looked down towards his dick, “D-dammit, Fenrir! My cock's been hard all day long! This shit hurts, ya'know!?" Touch! “Gah!?"

“Kufufufu~ Oh, I know it hurts," Fenrir replied before standing upright before him, “Okay. Trying to tutor you when you're sporting this erection will prove... difficult. So we'll delay your session for a few moments while I satiate your manhood... and get an early payment."

There was a sadism in Fenrir's voice, one that mixed with her sardonic tone. Hearing it left Leo feeling understandably uneasy. On one hand, he'd finally gain a release from a pain that had been torturing him all day long. On the other hand, he had no idea how the dark elf was going to do it! What if she summoned Princeton again!?

As his mind raced with thoughts, Fenrir drew closer. Her taunting giggles filled the air as she pushed her hands through her hair, tossing it up once or twice while her emerald eyes trailed down his body. It was so tall, so long, so thick! And it arched upwards as if to defy gravity! The more she looked at it, the more she snickered... and the more her mouth began to water.

Brushing her hand along her head, Fenrir tucked some hair behind her pointed ear... before bending over. More... more... morrreeee.

Grip!

“Hrrrgkh!?"

Fenrir's gloved hand wrapped around Leo's cock, snapping him from his thoughts. When he gazed forward, he came face to face with the dark elf's back. She had bent over, her body in this perfectly aligned 'L' shape with her head hovering above his cock. Gripping his dick tight, she aimed it up with her face, while her green eyes stared towards its bulbous head. Pushing down, just a little bit more, and--

“Shlip! Nnmmm~~~"

“Oooooh! Fuck!"

Euphoria.

Fenrir pushed down, capturing the first fourth or so of Leo's empowered cock into her mouth. There was no hesitation to the dark elf, no anxiousness. She pushed down around him, spreading open her luscious lips, and letting her warm maw capture him.

Not only had Leo's dick been strengthened, but so too did his taste. There was this salty and bitter flavor on his dick, having built up all throughout the day from sweat... and endlessly oozing precum. Now those combining flavors were dancing on Fenrir's tongue, drawing an erotic moan from her lips.

“Nmmmm~~~"

It traveled through Leo's dick, and went straight to his brain. Unfortunately for him, he couldn't really enjoy the sounds of her body too much, due to the feeling of her fellatio.

All day long – all day long! – he had been tortured by his underwear and slacks. Thanks to the dark elf's elixir, his cock had grown to a level of sensitivity that was almost maddening! So imagine how it felt being contained by Fenrir's perfect mouth!

Her teeth ground against his cock. Her spit tangled around him. Her breath heated him. And her tongue? Her talented tongue cradled his cock, swirling around him from the head down to glands.

Pleasure raced up and down Leo's body, making his legs buckle and twitch. He nearly fell over – he wanted to fall over – but somehow his legs remained firm enough to keep himself upright. Was that Fenrir's doing?

The dark elf kept her hand wrapped around his cock, forcing it to stand firm within her maw as her sucking increased in pace. Her pursed lips dragged upon his length, sinfully sliding up and down it as spit began oozing from her maw. It streaked down his length, gliding along his prominent veins, before snapping off and falling to the floor.

“F-f-fuucck...! I can't...!" Leo groaned as he placed his hand on Fenrir's head... making her come to a stop.

“Pop~!"

She looked up at him. Her alluring face was gone, replaced with a more oppressive scowl.

“No," said the dark elf flatly, “Hands behind your back."

Leo locked up, unsure of how to respond to her sudden order... other than obeying it that is. Like a puppet on the strings his hands snapped behind his back, holding together. Fenrir hadn't used any magic on him, hadn't cast a spell or anything. And yet the sound of her command was still enough to instill obedience within him, with the young man fidgeting in place slightly.

“Good servant," she said, a smile spreading on her lips, “Now then... shlip! Nmmmm~"

“Aaaah!"

Fenrir's mouth once again parted around his cock, returning to sucking down upon the first third or so of his cock. Pleasure ruminated up and down his body, drawing an orgasmic cry of pleasure from him. The dark elf's head bobbed up and down, these muffled and erotic 'Mm~! Hmm~! Nmmm~!' mixing with the lewd slurping sounds of 'Shlurp! Slurrrp! Surrrp!'

The rest of his cock was teased by her elegant hands, which gently stroked up and down his length. She traced her digits along his throbbing veins, bringing them down towards his large, tight, tennis ball-sized balls. Gripping them firm, she groped and massaged his sack, her touches soothing as well as erotic. Leo melted further beneath her, but kept his hands behind his back, and his body as rigid as he possibly could.

But his stance was faltering.

Why was she torturing him like this? It wasn't just her blowjob – which was amazing by the way – but it was her body as a whole. Leo's blue eyes traced up and down her form, marveling at her marvelous physique. The curve of her shoulders, the shape of her waist, the plumpness of her hips; she was so fucking flawless! And she maintained her body all while casually sucking his cock while standing perpendicular with it. Wasn't it difficult to maintain such a perfect position for so long? Fenrir didn't even flinch!

She just sucked, and sucked, and sucked, and sucked, and suuuuuccckked. And then she pushed down further.

“Shlorp~! Nmmmmmmmmm~~~"

“GGRRAAAH!?"

She was standing, his cock was enlarged. And yet, the dark elf pushed down further upon his cock, deepthroating him. Her wonderful esophagus was quick to tighten around him, seizing upon his dick, and holding him hostage. Another roaring moan was forced from Leo's mouth from the feeling and his head tipped back, while Fenrir continued sucking.

His cock was longer and thicker than it ever had been in his life, and yet she managed him without issue. Was this the skill of a demon? Her throat was even visibly bulging from the throbbing member she sucked on, and yet not even that was enough to hinder her! There was no gagging, no wheezing, no choking of any sort! She just...

“Nmm~ Slrrrp! Hmm~ Sluuuck! Mmm~ Shlurrrp! Hmmm~~~"

Her head continued bobbing back and forth, her tongue whirling around his cock. The pleasure Leo felt became too much for him to possibly defend against. He wobbled, then shook... and finally his body let out under him.

He fell back against a pillar of books behind him... and yet not even that was enough to stop Fenrir's fellatio. The dark elf even closed her eyes, her sucking growing more fervent. She was no longer seeking to please him or torture him, no... she was looking to finish him off. Her undulating throat, her licking tongue, her pursing lips, and the powerful vacuum force of her devious sucking, all finally built up to--

“GUH!!!"

SPLORT! SPUURRRT! SPLURRRRT!

“NNNNMMMM~~~"

Release...

Leo's unruly cock exploded within Fenrir's maw, shooting thick blast after thick blast of cum into her awaiting maw. His loads were copious before, but they were downright overwhelming now. They flooded and flowed into the dark elf's mouth, making her cheeks swell and her throat bulge from the large amount being deposited inside of her. There was so much cum, it even threatened to burst from her lips!

But it didn't.

Despite the massive amount of seed that would make any normal woman choke, Fenrir contained all of it. She couldn't let any go to waste: this was too precious and too potent to let spill on the floor!

As Leo's orgasm finally came to an end, he let loose a final gasp and looked down. Fenrir was still attached to his dick, still suckling him down. But she then pulled back – eeeveeerr sssssoooo sloowwwllyy – drawing her perfect, pouty lips down his enhanced cock. The veins, the shaft, the glands and head; not one end of his dick was spared the touch of her lips. And when she pulled back, she left his rod glistening with spit and saliva.

But not one bit of cum.

All of his seed was contained in her mouth, stuck between pursed lips and swelling cheeks. Despite this, the dark elf smiled as best she could, elated with what she was containing. Her tongue even swathed it around, indulging in its taste, its heat, its texture, its everything.

So thick. So gelatinous. So flavorful. So potent. So good.

Like before, Fenrir placed her hands together, held them for a few seconds, then pulled them apart. When she did, a familiar-looking purple bottle with a plugged cork sat in her palms. Removing its cork, she held it up to her lips, and--

“Nnaaaaawwww~"

Down his cum oozed, traveling like a sinful river of syrup. It flowed straight into Fenrir's bottle, collecting inside of it. Before, his load was capable of filling a much smaller container. Now things were different. Now, this much larger bottle was filled to the absolute brim!

Leo's eyes swelled in shock as the last bit of his seed was collected in her jar. Fenrir meanwhile closed her mouth, chuckled deviously, then plugged the top of her jar, keeping his seed contained within.

“There," she said, her emerald eyes staring up at him, “Wonderful, isn't it?"

Leo was so amazed, he couldn't speak. He just sat there, mouth agape and eyes wide, his body ruminating with the fleeting sensation of pleasure. And when he did finally muster the courage to speak, the only words that came out were--

“Lady Fenrir..."

The dark elf stood up before him, her body radiating with erotic beauty... and a malevolent power. She wasn't lying when she said sperm was a key ingredient to many spells and concoctions. What she didn't tell him, was that the sperm of mortal males was powerful in and of itself. It empowered Fenrir, causing this soft miasma to flow off her body like a demented aura. Leo sat in awe – and fear – of this aura, while the dark elf extended her arms out.

Gweeeaaaam!

Like before, a bright light emerged around Fenrir's body. Unlike before, Leo didn't pull back or wince. He watched as the light dominated his apartment, before fading to reveal her once again. Gone was her witchy robes, replaced with that erotic teacher's outfit he was familiar with... yet no less turned on by.

“Now then," said Fenrir as she tipped up her glasses, her lips curling into that devious grin, “Are you ready, Leo? Because we are not done yet."

Swallowing his spit, his chest swelled and he stood up. While his legs were weak and wobbling, he still pulled up his pants to cover his manhood as he approached the dark elf. She looked at him, reading the subtle signs of his body.

The hunger. The desire. The need.

But despite all of that...

“Okay... let's get to work..." he mumbled.

Fenrir chuckled.

…

“With that... I'd say our latest study session is adjourned."

You know what's a sure-fire way to kill whatever boner he sported? Math. Like, a whole lot of math. Numbers. Functions. Numbers with letters. Functions with letters. You know the deal.

An exhausted groan left Leo's lips as he leaned back in his chair. The wicked hard-on he had sported all day long was relieved by Fenrir's talented mouth, leaving his brain as nothing more than a sponge to receive her teachings. And something inside of him must have really ticked, because--

“You did well today," said Fenrir, making him glance over towards her.

The dark elf was no longer standing next to him, nor standing behind him like some looming specter. Instead, she sat on the edge of his desk, one crossed over the other as she wore this teasing smile on her lips. He looked up at her, wearing an expression that was crossed between annoyed and drained. Even his shaggy hair seemed shaggier... if such a thing was possible.

“Is everything okay, Leonardo?" asked Fenrir with this taunting chuckle, “You don't seem as... dramatic as you usually are when we finish."

“I'm too tired..." he replied before blinding twice, “Haaah..."

“Kufufufu...! You should feel proud of yourself," the dark elf countered, causing him to raise an eyebrow, “Very few times did you make mistakes on your equations, and you didn't get as frustrated as you usually do as well. You were very... focused today," she tilted her head to the side, “Kufufufu... I wonder why that is."

She phrased it like a question, but he knew it was anything but. Not that she needed to say why he was so focused. His own gaze fell down between his crotch, staring at where his manhood was. It had returned to normal... yet he could still feel the phantom sensation of torturous pleasure he had endured all day long.

“You really are a demon," he said rhetorically, causing Fenrir to raise her arms above her head and push out her chest, putting on a dynamic pose for his viewing pleasure.

“Kufufufufu! Are you just now realizing that?" she replied in a sarcastic manner... before pulling herself off his desk, “Haaah... now then... I shall return to my realm."

“Wait? What? Really?" Leo said as he straightened up.

Fenrir chuckled in response, her hand pointed out towards the empty spot before her. Like time and time before, her doorway emerged from the floor, its sinister miasma flooding through the room. But before she walked through it, she turned to face her 'student' as she crossed her arms beneath her chest.

“You look disappointed, Leo," Fenrir said with this light chuckle, “Is something wrong?"

“Like... uh..." he shrugged his shoulders, “Aren't you going to take your payment?"

“Kufufufufu! I already collected my payment, remember?" she replied, causing him to lower his head, “And it was already very copious."

“Right... Uh... I guess I forgot..." he mumbled before looking back up at her, “But... tch... I guess… I thought you'd still want some more..."

“What 'more'?" the dark elf asked whilst leaning forward, “If I drained your balls again, I'd only get nothing but a paltry pittance. I wouldn't waste my time or yours doing something so pointless..."

He opened his mouth to make a counterargument... but she was right. Even if he beat his dick as hard as he could, he wouldn't give her a load anywhere close to what he produced earlier.

But let's be honest; that's not why he was asking if she needed her 'payment'. They both knew why he was really asking... and the knowledge of it caused a furious blush to form on his cheeks. He even palmed his head and shook it, while looking to the side in defeat.

Was he already so whipped by her, that he looked forward to 'paying' her? He should have been embarrassed – and he was... but he also found a certain joy in exposing himself before her. Of course, he'd never admit it though! Not to her... and not even to himself...

But Fenrir didn't need him to admit it; she already knew what he wanted! It's not like he was hiding it well.

Chuckling lowly, the voluptuous dark elf walked away from her door with her hips swaying from side to side. Leo – noticing her out the corner of his eye – looked at her, watching as she approached him with her arms outstretched. Her every movement – from the movement of her legs to the sway of her hips – caused her bountiful chest to bounce and wobble in his eyes, attracting his gaze forward. He was like a moth to a flame; he couldn't look away even if he wanted to. And before he knew...

Grab! Plap!

He was hugged up against Fenrir's bosom!

Leo's eyes grew wide as the soft and supportive chest of the dark elf cradled his head. She was so warm, her skin so flawless, and her hold so firm! Fenrir's arms wrapped around his head, embracing and snuggling him up closer to her chest so that he could get lost in it.

And 'get lost' he did.

These tits. These amazing tits! How many lewd thoughts has he imagined about these tits? How many times has he fantasized about snuggling up against them, kissing them, or just hugging them? Too many times to count. Hell, with the clothes she wore, it was as if she was purposefully flaunting her flawless bosom!

So as she hugged him, he just... sat there. Why bother moving? Just enjoy her body. Enjoy the feeling. Enjoy the warmth. Enjoy the smell. Oh. She had such a powerful scent. It was erotic, but also firm and professional. Smelling it melted Leo from the inside out.

And then Fenrir's hands slid up. Gripping the sides of Leo's face, she pulled him up from her tits so that his blue eyes could meet her green ones. She was grinning. He was dazed. He was so dazed in fact that he couldn't fight back when the dark elf lifted his head... and pulled him in close.

Wait... couldn't 'fight back'? Heh... why would he ever fight against this?

“Nmmff~"

“Mmm...?"

Leo's eyes grew twice as wide. Without warning, Fenrir kissed him. Her perfect, pouty lips pressed against his thin ones, taking him into a kiss that instantly fried his brain. At that moment, his whole world was focused on her and her alone. Nothing else mattered.

“Nmmph~~"

“Hfff..."

Fenrir's tongue... pushed into his mouth. Gently, it ground against Leo's tongue, coaxing him to start kissing back. For several moments, the two danced tongues and swapped spit... as well as swapping something else.

Something that was kinda sweet. Something that was kinda sour. Something that was kinda familiar.

Leo's eyes grew wide.

Oh no...

“Nmmph... Chu~"

Fenrir pulled back, breaking their lips from one another. She then stared into his face with her green eyes aglow... and her lips curled into a devious smile. Leo could only stand there, stunned by what happened... and knowing all too well what was going to happen.

“Until next time, Leonardo," said Fenrir as she pulled back, “Take care of yourself! Kufufufufu!"

Retreating to her doorway, the dark elf opened it up and entered inside, vanishing into that void of darkness. When the door closed shut behind her, it sank into the floor, disappearing and leaving Leo standing there.

For several moments that felt like an eternity, he remained as rigid as a statue. Then his head slowly tipped down, staring towards his crotch.

“Ah shit..."

…

Thursday...

It was in her mouth! The fucking elixir was in her mouth! Shit! How was he so fucking stupid to not see that coming!? Like some horny idiot, he was so enraptured in the kiss, that he didn't realize she was force-feeding him the elixir until it was too late! Wait, 'force-feeding'? There was nothing 'forceful' about it! He greedily and readily slurped it up! Now look at him, sporting his enhanced member again, and being tortured by it... again!

Gah!

It was cool today. A bit windy too. The skies were gray, and the ground was fresh with recent rain. It gave Willington a somewhat murky and muggy feeling, but, eh, he kinda liked it. Sometimes you prefer gray and cool days as opposed to sunny and warm ones. Especially when your body is relentlessly sweaty, and your cock is harder than a fucking DIAMOND!!!

Another day of classes, another day spent having his pants torture him. He had gotten better at hiding his pleasure... but only barely. He was quite sure Emma noticed him shift about like a blushing, horny idiot. Hopefully she didn't think he was a pervert or anything.

He wasn't going to hold his breath...

Returning to Railway Apartments, Leo marched up to his home, opened the door, entered inside, and--

“Fenrir! ACK!?"

Tumble! Fall! Thud!

He immediately walked into books. Damn. How many times was he going to do that?

Leo fell over, collapsing upon his floor with several pounds of books falling atop him. While pain raced through his body, the annoyance he felt was stronger, numbing him. Instead he growled and looked forward... where he came face to face with Fenrir's perfect feet.

The dark elf stood before him, her arms crossed, and this wicked grin on her lips. She could see how he suffered, and she indulged in it.

“Must you be so loud?" Fenrir asked, “I am right here, Leonardo."

“Grrrrggh! You...! Gggh!"

Pushing aside the books which sat upon him, Leo launched up on his feet before Fenrir, his chest puffed up and face fuming with rage. But the dark elf remained unbothered.

“Again!?" he growled, “Wasn't once good enough? I filled a bottle to the fucking brim for you!"

“Really? You think that one bottle was going to be enough?" Fenrir replied, “The week is not over, Leo, remember? I'm not going to stop until we're done with your tutelage. Besides, you were far more focused during yesterday's session. I surmise it has something to do with your mind being clear following your release. Soooo..."

“So... what?" he shrugged his shoulders, “You plan on making me cum? You think that'll help me study more?"

“Kufufufufu... yes," Fenrir answered as she pulled back, “So before we start your session, I'll take my payment first!"

That wicked grin on her lips growing, the dark elf grabbed Leo by wrists and began guiding him over towards his couch. His face remained indignant, but he didn't fight back, allowing her to sit him down. Looking up, he gazed upon Fenrir's smirking face, watching as she placed her hands together, and--

Gweeeaaaam!

There it was again; her titillating teacher clothes. Whatever anger Leo felt almost instantly vanished as his cheeks instead turned red from desire. Looking Fenrir up and down, he watched as the dark elf placed one hand on her hip, while her other hand performed a flourish through the air, where--

CRACK!

“Aah...!"

Her riding crop reappeared, snapping through the air and causing Leo to stiffen up. Glued to the ends of that leather whip, he watched as she pulled it over towards her tits. Gently Fenrir teased her perfect breasts with the end of the crop, sending sumptuous jiggles which quivered throughout her bosom.

“You like them, don't you~?" whispered the dark elf rhetorically, her erotic tone tickling her ears, “Just like yesterday. All I did was hug you to my chest, and you were utterly entranced. Kufufufu~! It's okay. There's nothing to be ashamed of. You cannot fight against your lowly mortal biology."

He really couldn't.

Leo's mouth hung open from the sight of her tits, watching her 'Tap~ Tap~ Tap~' them again and again. The sight was so enthralling, it was almost enough to make him forget about the powerful throbbing between his legs. Almost. Let's be honest, nothing could truly pull him away from the painful pleasure he was suffering. The constant teasing from his pants and underwear didn't help things either.

Thankfully, Fenrir stopped teasing her breasts. Bending over much like she had done yesterday, she flaunted her flawless figure as she easily stood perpendicular above his cock. Bringing over her hands, she undid his pants, opening his fly, and freeing his cock with a visible and audible--

Fwip!

The dark elf snickered as the familiar sight of his cock revealed itself. Leo sighed, feeling embarrassed... but not as embarrassed as before. Why bother? She's seen his dick plenty of times by now. Instead, his manhood throbbed between them, standing tall and proud all on its own.

“Aaha!?"

A sharp gasp left Leo's lips as Fenrir pulled over her riding crop, dancing the tip of it upon his cock. Excruciating shudders traveled through his body as the bristles of her flog swiveled around the head of his swelled penis, teasing his sensitive cock-flesh. From side to side she toyed with his member, causing him to grip the cushions beneath him tighter with his strong hands.

Pants, moans and groans left Leo as the dark elf toyed with his dick. She'd look up at him, chuckle and wink, but then her green eyes would stare back down towards the length she toyed with. All those proud veins, that thick head, that gooey pearl of precum; it was like his penis was begging to be devoured.

Mmmmmm~

Well, she would devour his cock. Just not in the way he was expecting. For instead of opening her mouth, Fenrir drew closer... and hovered her breasts above Leo's dick. His mouth closed shut and his eyes grew wide, watching as she aimed her tits with his dick. And once everything was perfectly aligned, she moved down...

Slip! Plap!

“Haah!?"

Leo's big, long, thick dick... slid right between Fenrir's big, soft, busty tits!

On both sides he was held hostage by the dark elf's perfect breasts. Her smooth tit-flesh brushed along every inch of his enhanced dick, teasing the shaft, the veins, even the bottoms of his glands! But his cock was so much longer now thanks to her elixir, that it stood tall from the valley that was her tits.

Fenrir chuckled as the doming head of his pulsating penis throbbed before her eyes. Pursing her lips, she shamelessly kissed the front of his length, making it bounce. Precum oozed from the slit and down the side, glistening in the light of his apartment, where it tracked upon the tops of her tits. Chuckling more, the emerald eyes of the dark elf remained glued to his dick while she pulled over her riding crop.

Not only were her tits wrapped around his dick, but Fenrir began teasing the tip of it with her riding crop as well. Swaying her chest from side to side, she caused her breasts to lightly batter his cock, while the fibers of her tool swirled around his glands. The softness of her warm tit-flesh combined with the harsh leather of her riding crop, both sent jolts of pleasure racing up and down her spine.

“Gaah... hggh...! Shit..." Leo moaned, “Aaah...!"

Fenrir's grin spread wider as she began swaying her tits left and right, gently grinding them along his cock while her riding crop continued teasing his head.

“You can move if you want~" she whispered, her emerald eyes glowing, “I give you permission."

Leo didn't hesitate...

Plap! Plap! Plop! Phlap!

Lust taking over his body, he began to relentlessly pound into Fenrir's tits, making them bounce, wiggle and jiggle before his eyes. His cock – harder than diamond and hotter than molten magma – penetrated her tits, shooting upwards with all the strength he could muster.

And Leo had a lot of strength.

His dick pounded through her tits with enough force to make them blur! He certainly lacked restraint... not that Fenrir was complaining. Even as her tits were being so thoroughly fucked, the dark elf wore this wicked grin on her lips.

Placing her hands to the sides of her tits, she gripped and pushed them together, tightening their hold around Leo's dick. A crooning howl of pleasure left him as he laid back on his couch, his cock throbbing even more. Being wrapped in Fenrir's tits was like being wrapped between two soft and toasty marshmallows! He never wanted to be free of this sensation!

Shlap! Plap! Plop!

In tandem with Leo's thrusting, Fenrir thrusted her tits back down to meet him. The full weight of her breasts fell around his cock and on his waist, sending more pleasure racing to her brain. His brain was starting to short-circuit again as he struggled to even think. He just needed to... he needed to... he needed to...

SPLURT! SPLOORT! SPUUURRT!

“Ah-ha! Yeeeesss!"

Was... was his orgasm really that strong? He didn't get the chance to see it last time since it was in her mouth. But now, there was nothing hiding the sheer volume of his climax.

Ropy bullets of spunk shot out from his dick, launching high enough to strike Fenrir's chin. She flinched, pulled back too, but that grin never left her. His cum spread out over her tits like the splintering webs of a spider, marring her chest in his fragrant lust. Several more blasts were launched up from his dick, being just as plentiful as his first few. His balls were working overtime, refusing to stop until he physically couldn't keep going.

More blasts! More ropes of cum! All of them sprinkled upon Fenrir's tits, before sliding down to collect between her erotic cleavage. If one were to stare upon her, glazed in cum with her sultry teacher's outfit on, they'd think she was some sort of pornstar. She didn't just look slutty, she smelled slutty too, as Leo's musky odor soaked into her flesh.

But Fenrir didn't mind. Not. One. Bit. She grinned, smiling from cheek to cheek as she basked in his sperm. Leo looked upon her, his mouth opened as he panted for breath. But when he finally mustered the courage to speak...

Bweeeaaam!

A ray of mauve light emerged from around her body. With her magical might, Fenrir collected all of that cum that stained her body into an orb of magic. Said orb raised up between the two... before she compacted it down into a glass, translucent bottle. And just like yesterday, that bottle was filled to the top!

Fenrir – completely cleaned of all his spunk – held that bottle of cum in her hands with a beaming smile of pride on her lips. Leo looked up at her, his mouth hung open as he steadily returned to reality. He could feel a draw on his body – constant climaxes like this could not be good for him – yet he stood up regardless.

“Leo...?" said Fenrir as she faced him, “Are you okay?"

He shrunk slightly.

“Let's just... get to work..."

“Kufufufufufufufu!"

…

Friday...

Touch...

“Hnn...? Mm...? Wh... what are you doing?"

Fenrir was a demon. He had to keep reminding himself of this fact. Sure, she was a tall, voluptuous and sexy dark elf... but that didn't make her any less of a fiend. He thought her evil ways were focused squarely on teaching. Now he knew better...

Leo's pencil came to a halt. Leaning back on his desk, he looked down. There on his thigh, gently rubbing back and forth, was Fenrir's hand. It stimulated his body, sending a heat through him... which came to center on his groin. Between his legs, his manhood started to swell, causing a blush to form on his cheeks... and for his gaze to travel over.

Instead of standing behind him or sitting on his desk, the dark elf was instead sitting next to him... and glaring at him like a focused hawk. Despite her serious looks, she propped her head up with one hand, while her other hand started to stroke up and down his thigh. Her touch – gentle though it was – stimulated his body, forcing his cock to grow hard.

“Fenrir... I'm studying..." he whispered abrasively, only to be answered with her cool chuckles.

“Oh. I know~" she replied, her sardonic voice reverberating in his ears, “You're so serious and tense, Leo. Maybe it was a bad idea not giving you the elixir yesterday. You're not as talkative as you usually are."

“Isn't that a good thing...?" he muttered back as he gritted his teeth, “Shouldn't you want me to focus? The first day, you were on my ass harder than a drill sergeant..."

“Yes, you're right; I do want you to focus," Fenrir replied, “But... I can tell you're not really focusing. There's a difference between focusing, and being quiet."

“Wh-what...?"

“Tell me..." she tapped his paper of notes, “Can you tell me what X is in this equation, if 2 is less than or equal to X, which itself is less than or equal to 18?"

“I uh... um..."

Leo's face turned pale as he stared down at the paper in front of him. This was the equation he had been working on for the past ten or so minutes, and had written dozens of notes on it. So many notes in fact, that one would assume he'd have come to an answer three minutes ago! And yet – like a toddler forced to eat green beans – all he did was sit there and waste time.

Shit. He thought he was making progress this entire time. Instead, he was just on autopilot... and his autopilot wasn't even good.

“Fuck..." he muttered, causing Fenrir to nod.

“Exactly," she said as she turned in her chair to face him directly, “You're letting your body move on its own instead of doing any thinking..." he head tilted to the side, “Why is that?"

“I...! Aah... I..." he shrugged his shoulders and deflated, “Shit... I don't know..." he shook his head, “Maybe I'm too worried about that damn exam in a few days. I... I guess I'm stressing out."

“Hmmm... stressing out, you say..." Fenrir said as she took in a deep breath, “Haaah... well... I suppose it cannot be helped. You lowly mortals. You worry too much about such trite and insignificant things."

“It may be trite and insignificant to you... but it means the world to me..." Leo replied while Fenrir stood up, “Hm? Are you going somewhere?"

“No. We're going to take a break," she answered, making him stiffen up, “There's no point in me trying to whip your brain into place if you're not going to focus. Clearly, you need to take a few moments."

“Wow? A break...?" he replied, his voice both sarcastic yet genuinely surprised, “I can't believe it..."

Leaning back in his chair and palming his head, Leo brushed back his hair as he gave an exasperated groan. Fuck. Why did studying have to be so mentally draining? It was only, what, ten o'clock? Well before his bedtime. And yet, he felt like he could sleep the next twelve hours with ease.

Ugh...

Fenrir meanwhile stood behind him, where she placed her hands together and stretched them out. Flaunting her limber physique once more, she easily maintained a 90 degree angle with her body, with her upper torso pushed out, and her arms above her head.

It was her silhouette Leo noticed first. With how she was standing, the light from above cast her shadow over his gaze, flaunting her illustrious figure. He leaned back in his chair and his cheeks turned red as his eyes ran along her back, her butt, and her swaying tits.

“Nnh..."

Despite all of the skin Fenrir showed, even to the point that her clothing was skintight, he hadn't seen her naked yet. Even when she gave him that titjob the other day, she did so with her blouse and bra still on. Was that more of her demonic torturing? It was working.

Tip! Tap! Tip! Tap!

Nm? Fenrir was walking closer? What was she do--

Grab!

“Huh?"

The dark elf's arms fell upon his shoulders, wrapping around his neck, and hugging him close. Leo's eyes grew in size as he was suddenly hugged up against her breasts, which gently cradled him. Confused, he looked up, his eyes meeting hers... and the smile she wore on her lips.

“Lady Fenrir...?" he said, “What... what are you doing...?"

She didn't respond. Instead, she raised her hand... where magical symbols appeared around her hand. They were purple in color, and contained characters he didn't understand. Just a purple ring which pulsated and glowed. As they did so, the buttons of his shirt were magically undone, as well as the zipper and fly of his pants.

“It's not as intimate..." she whispered as his body was steadily revealed to her, “But it gets the job done, wouldn't you agree?"

“Aah...? Wh...? What are you doing?"

“Shhhhhhh~" Fwip! “There you are~"

Revealed to them was his cock, standing tall and firm. It wasn't empowered – Fenrir thankfully spared him that elixir today – but he was still as rigid as humanly possible.

No longer embarrassed by exposing his throbbing manhood to the dark elf, he stared at himself while she pulled back. Glancing over towards the dark elf, he watched as she sashayed over towards the front of him... before--

Pat!

“Nm...?"

Sitting down on his lap.

Leo wore a confused face as the dark elf sat on him. The weight of her body pushed down upon him... while her curvy and shapely ass pushed up against his dick. Oh. That's why she undressed him. So that he could feel the smooth and pristine leather of her skirt.

It slid and ground against his cock, sending pleasure up his body, and making his dick jump. Leaning upright in his chair, Leo let out a gasp and he looked up, drinking in the image of Fenrir's frame. Her back was so shapely and erotic, with her peach-shaped butt and curvaceous hips. And now his dick was riding up the valley that was her ass, with the leather of her skirt teasing along him.

“Nggh...! L-Lady Fenrir..." he mumbled, “Wh... aah... What are you doing?"

“Helping you relax," she answered as she reached down and gripped the edge of her skirt.

Pulling it up, she revealed her butt to him in all its glory. Its curvy shape, its plump size, the pristine flesh, all with her elegant black panties sliding between her butt. Leo's chest swelled at the sight, his eyes growing wide.

“Do… butts this size come standard in Daemonium?" he joked... where he almost instantly regretted it.

Not because the joke was cringe or anything – he tells cringe jokes all the time! Mostly because, well, Fenrir's a demon! He needed to keep reminding himself of this fact!

He expected her to punish him. Maybe summon Princeton. But she didn't. Instead, Fenrir looked over her shoulder towards him, shooting Leo a teasing grin.

Left to right she swayed her hips, grinding her ass more against his cock. It throbbed beneath her touch, sputtering and spreading his precum upon her curvaceous ass. His clear jizz streaked down her butt, sliding and sliding... sliiiddddiinnggg.

Leo wanted to lift his hands and touch her... but he knew better. Unless she had given him the order to do so, he was to remain still. So he gripped the handles of his chair, his teeth gritted as pleasure continued rising within him.

“Do you...! Ngghh! Do you do this often...?" he asked as Fenrir ground against his cock.

“What? Ride men like this? You think me some sort of whore?" the dark elf replied, making him shake his head.

“N-no! Not a whore! A dominatrix!" he answered, “Gaaah! There's a difference!"

“Kufufufufu~ You're right. There is a difference. I'm proud to know you've learned something during our time together!"

Plap! Plap!

Pushing down harder against Leo's dick, Fenrir flattened it against his belly. In saucy circles she pressed her ass against his cock, grinding harder against him. His moans shifted as the full weight of his tutor pinned him in place, and the softness of her pliable ass sandwiched him.

“Go ahead~" Fenrir called, her voice like a murky bog of lust, “Touch me. I know you want to. So I give you permission."

Permission. That word held such strength when Fenrir said it. Permission. Yes. He wasn't allowed to touch her until she gave him expressed approval to do so. And when he got that approval, he was quick to indulge in it.

Leo's hands flew forward, where they grabbed and squeezed upon Fenrir's curvy butt. Giving her a tight squeeze, he drew this chuckle and moan from her lips. He wasn't indecisive in the least bit! Squeezing her ass, groping her ass, kneading her ass; he toyed with her butt like a man indulging in a drug.

“Kufufufufu! Oh you mortal men! You're all the same~"

Fenrir didn't mind how desperate he was. The dark elf enjoyed it.

Resting on his lap still, she shook her hips left and right, moving slowly as to not disrupt his hopeless groping. He brought his hands around to the bottom of her butt, where he clutched and lifted it. More chuckles left the dark elf, though they shifted into groans as Leo grew bolder.

Pushing into her, he forced Fenrir to stand up from his lap. She bent over, placing her hands on the smooth surface of his cluttered desk, while pushing out her hips towards him. This damned figure of hers; why was it so fucking perfect? His gaze was utterly dominated by the sight of her ass, which reflected in the surface of her cool blue eyes.

“I know what you want to do," Fenrir whispered, “It's so obvious that it's almost sickening. Here, you pathetic mortal..."

Reaching down, Fenrir slipped one of her fingers into her panties and pulled it up, revealing a tiny gap for him. Beneath was the black fabric of her panties one way, and the curvy flesh of her ass the other.

“Right here," she said, “Slide your obscene cock right here."

Was he going to outright fuck her? No. Was he going to pass this moment up? Of course not!

Getting up off his chair, Leo positioned himself above Fenrir. She chuckled, her emerald eyes leering at him with a smirk on her lips. He himself scrambled for a moment, gripping his dick and sliding it into that tight gap.

“Aaaaaaahh...!"

A shudder traveled down Leo's spine. One way, he felt Fenrir's panties. The other way, he felt her warm and perfect body. Both cradled him, hugging him inside deep as he gripped her waist. He doubled over, nearly fell upon the dark elf too. But as desire raced through him, he gripped her hips tight, pulled back with his own hips, and--

Pat! Plap! Plat! Pap!

Like her tits the other day, Leo fucked Fenrir's ass... well... kinda. His cock slipped along her butt and panties again and again, thrusting into her like he was fucking her pussy or asshole! It didn't matter that he wasn't surrounded in a warm and moist tunnel. The pleasure he felt right now was still indescribable!

“Aaaaaaghh!" he moaned, making Fenrir chuckle.

“Look at you. You're no better than a horny beast," she commented, “Swinging your hips so wildly like a feral ape. I understand now why you need my help with math!"

Her words didn't fail to reach him; he heard them all. So... why did that make him even hornier? Why did he feel such incredible levels of pleasure?

Leo's cock continued grinding along Fenrir's ass, slamming into her with enough force that quakes were sent racing through her butt. Objects on his table started rattling as well, while her tits ground against its surface. It may not be outright fucking, but damn was it close!

Leo's thick member – so long and with such proud veins – stood out on the underside of Fenrir's panties with a prominent outline. His precum – endless and sticky – oozed upon her ass, and formed a stain on her underwear as well. Meanwhile, his balls smacked against her butt, tightening, and ready to unleash its load.

Just... a few... more 'Plaps!', and...

“GUH!"

Spurrt! Sploorrt! Splurrrt!

“Nmmm~! Kufufufufu!"

Leo's length erupted, shooting out his seed with great force and power! It spread out upon Fenrir's ass like the blasts of a shotgun, staining the curves of her butt and painting it white. There was so much cum, her panties couldn't contain it all, causing some to explode out from the gap she created for him. What was left formed a dark stain on the underside of her panties, which darkened quickly.

Shlip!

Leo pulled back, drawing his cock from her panties and ass as he did so. Cum was flung out from the action, staining Fenrir's skirt and back while he fell into his chair. Letting out a deep breath, he palmed his sweaty head and rubbed it, while the dark elf stood up. Damn. All he did was grind his cock against her ass, and he was drained that much? Maybe it had been a while since he last had sex...

Fenrir meanwhile kept her hands on the desk's edge, where she tauntingly shook her ass in his face. His gaze snapped forward as he watched his cum slide down her inner thigh, astonished by how voluminous his load was even without her elixir. Maybe some of it lingered in his blood.

That's not good!

Fenrir however, wasn't too bothered by the cum that stained her clothes. Why would she be when she could easily bring over her hand, and--

Snap!

Magic sparkled from her fingers as she gave that finger snap. From it, Leo watched as his cum traveled down her ass and through the fabric of his clothes, where she collected it into that orb of magic once again. And also again, Fenrir turned around, where she condensed that orb into a physical bottle with a cork.

“Kufufufufu! Such a hearty payment today, Leonardo," said the dark elf as her green eyes swept over to him.

“Um... r-right..." he mumbled back... where her eyes suddenly grew serious.

“Break time is over," she said, that erotic tone in her voice completely gone, “Pull up your pants, button up your shirt, and let's get back to work."

“Ugh... right..."

…

Saturday...

He couldn't take it anymore. His body was getting weaker and weaker. He could feel himself become a husk of his former self. And why? Because of the one-two punch combo of relentless mathematical grinding, preceded or proceeded by a hardcore cock milking. One would think a man would love getting their dick milked of cum by such a hot mistress as Fenrir. One clearly hadn't dealt with Fenrir.

It was Saturday now. Monday was the day of his final exam. You know what that means, right? He had two days left before his inevitable doom. Even with his penis empowered as it was, he couldn't ignore what loomed over his head.

And, yeah, his cock was empowered again. He didn't even know how Fenrir did it the last time! He didn't drink anything, she didn't kiss him either. So... how did that happen? Fucking demon and her mysterious ways...

Resting on his couch, Leo gazed lazily up towards his ceiling. Saturday was one of the rare days he had off, with no work to bother him, and no classes to attend to. Typically, he spent the day running various errands, such as grocery shopping, bill payments, and of course, just hanging out with friends. It was a day to unwind as well as getting last minute chores done.

But not today. Today he just laid there on his couch, immobile and quiet. No errands need be run, no bills need be paid, and he had his phone on 'DO NOT DISTURB' so his friends wouldn't call him. Nope. It was just him and his couch, awaiting her inevitable arrival.

Tremble... Tremble... Treeeemmmbbbbbllleeee...

Leo took a deep breath as his apartment began rumbling. Straightening up, he looked over the spine of his couch towards the empty spot in front of his desk where he saw flames. Dark and purple in color, they sprouted up from the floor, emerging and surging outwards like a vent of fire. And from these flames emerged a door. Black in color, it had spiked edges, a Gothic design, and the symbol of a silver crown in the center of it.

This door – pumping with purple flames and a sinister miasma – hung before Leo, who stared back with indifferent eyes. Standing up off of his couch, he heard a 'Click...' and a 'Twist...' echo throughout his apartment as the door's knob began turning.

Eeeeeaaaaaarrrrrrrk!

The door opened up. Fenrir revealed herself.

Walking forward, the erudite dark elf emerged in his apartment, wearing her witch clothes as her emerald eyes fell upon him. He stared back, not even showing an ounce of surprise. His near indifference brought a smile to her face.

“Are you ready, Leonardo?" she asked, to which he took a deep breath.

“Lady Fenrir..." he whispered back before taking a deep breath, “Haaah..."

“Mm? Is something wrong, Leo?" she asked sarcastically as he approached her, “You seem... uptight~"

“I wonder why..." he grumbled back as they both looked down.

He wasn't wearing slacks, or jeans, or anything like that. Being lazy in his apartment all day, he sported a pair of simple sweatpants. And yet – despite how baggy they were – the prominence of his manhood was still visible. It pushed down his right pant leg, the outline of which was visible.

Snickering, Fenrir knelt down before him and his penis, her green eyes locked on his cock. So big. So lively. Drawing over her hand, the dark elf gently dragged her sultry fingers along his rigid outline, feeling it throb and push back against her.

“Marvelous~" she whispered before looking up, “You mortals may be weak of spirit, but your modular constitution makes you fun to toy with. Kufufufu! This elixir has..." Grab, “Hm?" Pusssh! Fwump! “Aah?"

Grabbing his pants, Leo pulled it down without hesitation, freeing his cock before Fenrir's eyes. The dark elf stared up at him, a chuckle leaving her lips as her grin grew in size. Bringing over her hand again, she directly touched his penis, dragging her hands along its taut surface.

“Does it hurt?" she asked. Was she being serious or rhetorical? He answered nonetheless.

“What do you think?"

“Kufufufufu! Yes. It does hurt, doesn't it?" she said as she stood up, “One would think you'd be used to the Piram Elixir since you've had it several times now. I suppose not."

“Fenrir..." he grumbled, before grabbing a hold of her shoulders, “I... I can't take it anymore…"

“You can't take... what?" she replied as she stood up, her voice oddly... provocative.

“All week long, you've been toying with me," he groaned, “Stretching, pushing your tits up to me, grabbing and hugging me, making me drink that fucking potion! And of course, sucking my dick, or giving me that titjob...! I..." he shook his head, “I just can't...!"

“Kufufufufu...! If you want to say something, then say it. I give you permission."

That word again: Permission. Why was it so much stronger now than before? Why did it send a thumbing through his body? Maybe it wasn't because of the word itself, but because of the meaning behind it. How it empowered him. Strengthened him. How it goaded him to do... this!

“Nmmff!"

“Hmm?"

Leo didn't say anything; he just did. And what he did was kiss her. He kissed her on the lips, pressing up to her and taking Fenrir by surprise. She was expecting him to be bold... but not this bold.

Not that she was complaining.

A muffled chuckle left the dark elf's lips as she wrapped her arms around his neck. Hugging him close, they deepened the kiss together, groaning as their tongues danced together. Around and around in swirling circles, trading moans and swapping spit, the two kissed with this desperate need for one another.

Fenrir's taste was phenomenal. He didn't get the chance to appreciate it before thanks to her forcing that elixir into his mouth. But without it there, he realized that she had a taste unlike any other. There was a spice to her tongue, one that coaxed groans from his lips.

Growing bolder, his hand slipped down towards Fenrir's waist, wrapping around it. She had so many luscious curves; he wanted to explore all of them. So his hand dragged upon the curves of her hips, running along their bend as he came down to her thighs. The dark elf wiggled her hips in response while drawing up her hands, placing them to the sides of his face to frame his with her own.

For several more moments they sat there, kissing one another. The lewd suckles and smacks of their lips bounced off the walls, drugging Leo and his senses. Fenrir used the opportunity to push against him, guiding him back to his couch... and knocking him over onto it.

“Aah...?"

He fell back into his couch, gazing up towards the dark elf as she loomed above him. Grinning from cheek to cheek, these taunting snickers left her lips, while that familiar bright light emerged around her body.

Gweeeaaaam!

Once again Fenrir's clothes changed... but it wasn't into those sexy teacher clothes she usually wore. Instead, her clothes changed into something far more... dangerous.

It was leather.

She wore this odd top that felt like a dress... but wasn't. The top of it hugged close to Fenrir's upper torso, while the bottom opened up around the front, exposing her navel, her legs, and her pelvis. The only thing shielding her womanhood was what appeared to be a pair of metal panties. They hugged her waist, clinching upon her curves, while fishnet tights extended down towards the platform heels she was wearing.

The bodice of her gown cupped, lifted, and supported Fenrir's perfect bust, flaunting them in all of their glory. Her cleavage was free to be ogled as well, with her only covering being the fishnets atop her chest.

If the clothes she wore before was befitting a witch, and she often switched into that sexy teacher's uniform, then this was the attire of a true dominatrix! And just in case he wasn't quite sure, Fenrir performed a flourish of her hand, and--

Crack!

Her riding crop appeared, snapping in the air with this sinister strength.

Placing a hand on her hip, Fenrir stood above Leo with regal strength and oppressive power. It made his body shake with anticipation, while she walked closer with her swaying hips. There were words she said to him earlier this week; a promise of her capabilities in the bedroom.

Even the most extreme dominatrix would pale in comparison to one such as I. Kufufufufu~ the things I could do to you, the things I could make you do, and the things I would do for you, would make your head spin.

His head was spinning right now, and his imagination hadn't even been let free yet! Was there anything he wanted to request of her? Of course there was! But would it be wise to make a request of a demon? Probably not... but, dammit, he had come this far already!

“Ngh...! Lady Fenrir..." he whispered, while she drew her riding crop over, teasing it along her cheek.

“Yes, servant?" she asked.

Fuck. Being called a 'servant' made him so hot. Did Leo see himself as being a masochist or a bottom? No, not really. But when one is sitting here before the dark elf, then they'd find themselves forced into submission, whether they want to be or not. Her power was too great, too strong to willingly try and avoid it. She wasn't called 'Lady Fenrir' for no reason. She was a true 'Lady' in every sense of the world, and she demanded the utmost respect.

“I want to..." he mumbled... cutting himself off as he raised his hand.

Placing it on Fenrir's thigh, he gently stroked her hip, marveling at her body and physique. The dark elf said not a word, instead chuckling as she began bending her riding crop before him. Closer she drew, hovering her crotch in front of him. Leo's eyes trailed upon her armored panties... or, wait, was it a codpiece? It didn't really matter...

His eyes slid along the straps of it, coming to the latches that kept it hooked upon her hips. Silently, he thumbed at those latches... before looking up to gain her permission. Fenrir nodded. He unhooked the latches...

Fwip! Clank!

Fenrir's panties fell to the ground. Revealed to him was the dark elf's erotic and shapely pussy. It glistened with her arousing nectar, its lips being thin, her clit rigid, and her pubic hair... shaved in the shape of a triangle, with one of its points aimed down with her pussy.

Fenrir's pussy didn't just look beautiful, it smelled beautiful. Her erotic, womanly scent pierced the air and flowed into his nose, causing his chest to swell. In his mouth, he felt a bubbling of drool, rising as his hunger grew. Need... desire... they both rose in his chest, driving him to place his hands on her thighs, framing her pussy with his hands.

His head then moved in, his eyes closing shut, his lips opening, and--

“Nmmmm..."

“Kufufufu... good servant~"

Leo's lips pressed against Fenrir's pussy, capturing it. Sliding his tongue along her folds, he gave her steady licks, moaning as the taste of her nectar slid into his maw. It was sour... tangy... and the more he drank it, the better it became. Moans started flowing from his maw and into her body, sending pleasure racing through her body.

“Oh yes~" Fenrir moaned as she gripped her riding crop tighter, “All you need is a leash, and this would be perfect. Kufufufu~"

Placing her hand on his head, the dark elf worked her fingers into his scalp and him tight, pulling him in closer to her snatch. Emboldened by her, Leo doubled his licking of her pussy, moaning more and louder as her taste grew more refined.

As he ate her out, her other hand trailed up her illustrious body. It traveled up her stomach, dipped into her navel, rose up to her chest, and came to a stop at her chest. With a tight 'Clinch!' she gripped upon her tit through the bodice of her, squeezing and groping herself while Leo's cunnilingus grew again.

He kissed her folds, slid his tongue from the bottom to the top, even rose himself to bite upon her clit! But no matter how tough he thought he was with her, Fenrir never buckled or winced. She'd groan, moan too, but showed nothing in the signs of weakness. If anything, she appeared to grow stiffer.

“Keep going~"

He'd nod... but he was still busy eating her out.

With her order ringing in his ears, he pushed his tongue up against her slit... and penetrated her folds. His tongue slid apart her cunt, allowing him to delve inside where the tastes of her folds were at their strongest. Her pussy clamped around his tongue, squeezing him tight, and drawing him in closer. The tightness told him all he needed to know about Fenrir and her body, coaxing him to bring his hands up to clutch her hips and ass.

Her ass.

Oh. Such a curvaceous ass. He experienced it last night, but that was like a tease, an appetizer. He wanted to have the main course today!

Push!

“Nnn...?"

But Fenrir pushed him back, sitting him on his couch. Brushing her hand through her hair, the dark elf rose her foot and placed it down between Leo's legs. His eyes grew wide as he stared at her foot, and how dangerously close it was to his massive member. The tip of her platform heel pressed up against the bottom of his cock, making it bounce and throb even more.

His gaze slowly traveled back up, watching as Fenrir's hands came down to the middle of her leather gown. There laid a series of strings in the middle of her dress, ones she undid. They slipped through their holes, triggering this audible and 'Swip! Swip! Swip!' noise that echoed in Leo's ears. And as each string was let loose, the gown expanded around Fenrir's body as it no longer held taut upon her.

Plap! Plap!

Her gown parted down the middle, held up only by the fishnet straps that wrapped around her neck. In doing so, her entire body was revealed to him, with her gown flanking his sides like an erotic, leather portrait frame. The contours of her hips and the narrowness of her waist gave her this curvy, hourglass of a body. And her breasts – her big, shapely, busty, perfect breasts! – were out to be freely ogled by his blue eyes. They had a perky shape to them, standing against gravity, with hard, ebony nipples.

And ogle he did.

Leo gazed at her, astonished by what he was seeing. The dark elf meanwhile wore this wicked grin on her lips, her emerald eyes sliding down upon him like a predator seizing up its prey. A few sensual snickers exited her lips as she raised her riding crop, and once more--

CRACK!

It through the air.

“You should be thankful," said Fenrir, “You have the grand honor of sharing space with the likes of I, Lady Fenrir: Grand Mage of the Mordredus Wizard Court. I would make you beg... but I have something else better for you to do..." she raised her foot, “My heels. Remove them."

Leo nodded, obeying her without a moment's hesitation. Like the desperate servant he was, he gripped her platform heels, undoing their straps; one after another. Once freed, he pulled her shoes off, revealing her immaculate feet. This was the first time they had been so close to him since she first emerged from that door... and he groveled before her to save his life. Now there was no groveling. There was a desperation to experience her feet on his own.

Was this her doing during their time together? Not just to teach him calculus, but to teach him obedience? And like some stupid dog, he let it all happen without realizing. She really was a demon... and was far smarter than him as well.

But what's worse? Realizing that – on some level – you've been tricked? Or not caring that you've been tricked?

Fenrir raised her foot again, hovering it in front of his face as she stood on one leg. Leo's eyes traced along the shape of her perfect foot; from her toes to ankles; her sole to her heel, and everything in between.

“Kiss it..."

Again. Leo did not disobey. He didn't even hesitate.

Grabbing Fenrir's foot, he clutched it like a precious and fragile artifact. His thumb stroked along its curves and shape... while his head drew closer and closer. Pursing his lips, he tipped her foot down, and--

Chu!

His lips pressed to the top of Fenrir's foot, right at her toes in fact. This kiss was followed by another, and another. He peppered the top of her foot with a flurry of kisses, before sliding back down to the bottom. Extending his tongue, he licked along the side of her foot and its sole, drawing taunting chuckles from the dark elf's lips.

Leo himself was moaning. There was a unique flavor on her foot, one that sent shivers down his spine. All of her sweat percolated on these flawless feet, giving her a salty yet spicy taste that rumbled through his chest, and danced on his tongue.

“Good servant," Fenrir whispered, “Kufufufu~ Your dedication is noted. You may be poor at things you care little for, but the same cannot be said for the things you are passionate about. But in my personal opinion..."

Push!

“Nmmph!"

“I think that tongue of yours is better servicing me, than it is being silver~"

With slight maneuvering, Fenrir pushed her big toe into Leo's mouth. He grunted... but quickly adjusted to the feeling of her. Moaning around her, he suckled on her big toe, drawing on it, and bringing a snicker to the dark elf's lips.

“Keep going~" ordered Fenrir as she performed a flourish of her hand, “Just let me..."

She wasn't joking about that 'leash'.

Shling!

“Hmm?"

“Keep. Going."

Was he worried about what she was doing? Duh; she's a fucking demon. But did he obey nonetheless? Of course he did!

With an almost slavish devotion, he continued licking and kissing upon Fenrir's foot, unaware of what the dark elf was doing. With her finger hooking through the air, she caused...

Snap!

“Nghh!?"

A collar to wrap around his neck.

Be it from instinct or fear, Leo pulled back... only for Fenrir to force her toe into his mouth.

“Keep! Going!"

Her command ringing into his ears, he tightened his lips around her toe... and continued sucking on it. His drool streaked down her foot, glistening in the light of his apartment, while his blue eyes gazed up. Fenrir's illustrious body was so close in this position, giving him a straight view up towards her face. Her pussy, so wet and hot. Her midsection, so tone and flat. Her breasts, so busty and perky. And her eyes...

So emerald...

As Leo continued suckling on her toe, he felt the collar around his neck tighten. The grip was tight. Not tight enough to choke him, but tight enough to let him know escape was impossible. And to make sure he understood that, the dark elf pulled her hand back... where a leash sat between her fingers.

Staring at the leash in hand, Fenrir gave it a few jiggles, causing a 'Shling! Shlink! Shlink!' noise to echo out. She chuckled after... before bringing her gaze back towards him.

Tug!

“Nngghh!? Pop!"

Pulling on his leash, the dark elf forced Leo off of her toe. He grunted, gritted his teeth too, but could do little against Fenrir's control as she pulled him close.

“On your feet, servant~"

Obeying her once again, he got up on his feet, his face coming closer and closer to hers. Dammit. This submissiveness was thrilling. Was it because of Fenrir's power, or just her personality? Probably both. No. Certainly both. She drew him in; he could feel her breathing tickle his lips. Was she going to kiss him again? He pursed his lips, but--

Push!

“Nnghh!"

Leo fell down on the floor, sitting with his back to the couch... and his legs spread. He stared down towards his enhanced member, then looked up towards Fenrir. The dark elf chuckled at him, tugged on his leash too... then sat down on his coffee table. Sitting before him with one leg crossed over the other, Fenrir raised her foot, hovering it in front of him.

“My other foot," she said, “It demands your servitude as well."

Leo leered at her, wearing a face of annoyance... but it only served to make her chuckle more. Despite his abrasiveness, he grabbed a hold of her foot... and began kissing it. Like before, he dragged his tongue along her soles, kissed the top of her foot, and suckled on her toes. His devotion to her made her chuckle all the more... and caused that heat in her pussy to increase as well.

As Leo worshiped her foot, Fenrir brought her other foot over, hovering it above his crotch. With his spit oozing down her limb, she spread her toes apart; almost like a crab's pincers. And she brought that foot down, placing it upon his cock.

“Hnngh!?"

Leo's eyes grew wide. Fenrir spit-lathered foot was pressing against his dick.

The dark elf pushed down upon his length, letting him feel the individual ridges of her soles. They ground along his dick, sliding up and down upon his every inch. From his tight balls, along his bulging shaft and towards his swelling dome; she made sure to leave not one bit of his cock unexplored. Her stroking footjob sent pleasure ruminating throughout his body, coaxing muffled moans which reverberated through Fenrir's body. But even then, she was not yet finished.

With her big and pointer toe parted, the dark elf gripped upon his cock's head with her feet. It was a tight squeeze, one that made his chest swell, forcing a groan from him. Fuck, his cock was so damn sensitive! Her every movement was flawless, torturing him just as much as she was pleasing him. And when she gripped him, precum was forced from the tip of his length like a bottle being squeezed.

It oozed on her toes; sticky... thick... a prelude for what was to come.

Slide! Slid! Swip! Slipe! Slip!

“Hrrnnh! Hggghh! Hgggmmnh!"

Up and down, Fenrir brushed her foot along his cock, jerking him off. The pleasure mounted, his cock throbbing and pulsating without control. He couldn't even suck her toes anymore with how much his mind began to ebb and flow. So he just sat there, his eyes closed, his moans flowing without end, all while his cock throbbed more and more, harder and harder! And finally, rising up from his balls, through his shaft, and to his tip...

“Nnggh!"

SPURRT! SPPLURRT! SPLUURRT!

Was his cum.

Like an explosive geyser, Leo's cock launched his seed upwards, staining Fenrir's foot. His cum – thick and gooey thanks to her elixir – spread out and coated his mistress' foot. Bridges of seed hung between her toes and oozed down her sole, burning her flesh as it did so. And the smell? Oooooh, that smell was so much stronger as well. Thick and pungent, this was sthe odor of a randy male's desire to breed.

And the smell of Fenrir's bounty...

Bweeeaaam!

Thud!

A ray of mauve light emerged on Fenrir's foot, collecting all of Leo's spunk... while he fell over on the floor. As he panted desperately for breath following his orgasm, the dark elf collected all of his cum. It slid off of her foot and hovered into the air, where she tightened it into a ball of magic... and then condensed said ball into a bottle.

There was a slight problem however...

As he returned to reality following his climax, Leo looked down towards his cock. Normally, his member would start softening as the elixir's effects wore off. But that's not what was happening. If anything, his dick felt twice as hard!

“Um... Fenrir...?" he mumbled as he noticed this affliction.

After placing aside her recent 'payment', the dark elf stared down towards his crotch... where a curious--

“Oh!"

Left her lips.

With one hand still gripping his leash tight, and the other hand placed on her chin in a thoughtful pose, Fenrir crouched down near his throbbing penis. She even tapped it a few times, causing him to wince, and making it jump.

“I see..." she muttered.

“Well I don't!" Leo replied, “Wh-what's going on? Aaah...! My dick hurts!"

“Hmmmm... it looks like frequent usage of the Piram Elixir in such a short amount of time has caused its effects to soak into you," said Fenrir.

“They've done WHAT!?" he shouted, “Does that mean my dick's gonna be hard forever!?" Shling! “Gah!?"

“Calm down, Leo," said the dark elf with a smirk as she gave a tug to his leash, “It just means we'll have to be extra thorough when it comes to satiating you. It will probably take several climaxes."

“S-several?"

How many was 'several'? Was that actually seven? N-no. That was just three or more, right? Either one sounded painful and strenuous! Not to mention the look in Fenrir's emerald eyes.

Standing up, she loomed over him, her legs parted by his body. Did he want her to go down on her again? No, that's not it. She was hovering above his cock. Wait... was she actually going to--?

Tug!

“Nnhgghh!"

With another pull on his leash, Fenrir forced Leo to sit upright. He stumbled closer, bringing up his hands where he placed them on her hips. With a gentle grip, he looked up towards her smirking face, while she gave another pull of his leash.

“Go ahead," she said, “Touch me, servant."

With her expressed approval, he gently dragged his palms along her body, marveling at her figure and shape. His hands traveled up towards her chest, cupping the bottom of her bosom. Oh, these breasts. How many times had he marveled at these breasts? Too many times to count. And now, not only were they bare and naked before him, he was given the permission to touch them.

Leo squeezed Fenrir's tits, lifting and groping them. Her hard nipples rubbed against his palms, while his hands gave her a tight clinch. The fat of her breasts spilled through the cracks of his fingers, coaxing a groan from her lips, which shifted into a snicker.

“Such a desperate mortal," Fenrir quipped as she knelt down upon him, “Your obscene, pent-up penis is throbbing without end, desperate to feel my tight, moist pussy wrap around it. Kufufufufu~! You should be thankful, servant."

“Hnn...! Fenrir..." Press! “Haaah...!"

Down below, the dark elf's womanhood pressed against the head of his dick. From that slight touch alone, pleasure raced through his body, making him stop. But Fenrir didn't. With her hand grabbing his dick, she angled his length up with her folds, properly aligning things. She then brought her hands up... and pushed forward.

“Aah...?"

Leo laid on the floor, with Fenrir's hands pinning him in place. A blush adorning his cheeks, he came face to face with his mistress' grinning expressionl, all as she pushed her hips down.

PAT!

Pure euphoria.

Fenrir's butt wasn't just perfect. Fenrir's tits weren't just perfect. Fenrir's mind wasn't just perfect. Her pussy was perfect too.

When she pushed down, her cunt parted around his enhanced girth, taking it all the way down to the hilt without an ounce of discomfort. Her vaginal walls gripped upon his dick, her individual ridges stroking along every inch of him. It was like being wrapped in a tight fitted glove!

And she did it all with that smirk on her face.

“Kufufufufu~! Now then... move, servant~"

He didn't need to be told twice!

Placing one hand on Fenrir's side while the other continued gripping her tit, Leo pulled back with his hips, and--

Pat! Pat! Pat! Pat! Pat! Pat! Pat!

His hips launched upwards into Fenrir's snatch, thrusting with enough force that her perky breasts bounced. Each thrust caused her pussy to swell, gripping his dick that much tighter! And yet, she never moaned, never groaned, never screamed out in pleasure. She just grinned at him, her green eyes glowing with lust.

“Haaa~ Aaaahah~ Ooooh~" Fenrir panted as she raised her hand, pushing it through her silver hair, “That's it... kufufufufu~ Good servant~"

His guided thrusts were precise, slamming his length up and into the dark elf's pussy. She panted softly, groaned too, but never broke that smile, all as her emerald eyes stared down upon him. In return, Leo stroked his palm down her side towards her hip, while his hand gripped her tit tight. Even as he squeezed and groped her body, he never stopped thrusting his cock upwards into her snatch.

The seconds ticked by, and Leo's thrusts grew stronger, sending wave after wave through Fenrir's body. Her silver hair started jumping up and down, her ponytail whipping through the air. Her breasts too began bouncing faster, eventually blurring on her chest as his thrusting grew frantic and frenetic; faster and faster!

And yet she still never broke her composure!

The smile on her lips. The glow in her eyes. Not once did either break.

But he was breaking. As shameless as it was to say, Fenrir's pussy was too great. First-Rate, he would say. The tightening of his cunt and her gripping folds was like sliding his dick into a sex toy specifically made for him. But, no, that's not it either. The dark elf's pussy didn't just please him, didn't just squeeze him, but it possessed him, it lorded over him. He wasn't just fucking her, she was fucking him. And she wouldn't stop until she got her prize.

His balls. His large, tight, churning, balls. How they surged with cum, desperate to pump her full of it This tightening feeling continued to build, unable to be limited, slowed, or stopped. All he could do now was pull back his hips one last time, thrust them up, and--

“GAH!"

GLURK! GLORP! GLURP!

“Hnmph! Kufufufu! Good little servant..."

The sound of his internal orgasm audibly echoed throughout his apartment. Shit. Why was he so fucking loud? It must have been because of his elixir.

Meh... whatever...

Leo's virile male cum shot deep into Fenrir's pussy, coating her vaginal walls and womb. The moist depths of her folds were filled to the brim with seed, being so thick and copious that spunk audibly 'Splurted!' from her pussy, making a mess of his cock and balls. And yet, despite cumming full force like he was, Leo never stopped moving! His cock continued thrusting into Fenrir's snatch, fucking her as he was climaxing, letting his jizz cover every inch of her snatch. It's like his body was moving on its own, refusing to stop until his mistress allowed it.

His mistress...

Grinning like the demoness she was, Fenrir tugged on his leash, drawing out his fucking for as long as he could. He gritted his teeth as his head was forced off the floor, coming close to hers. The wicked grin she wore was at its largest now, and the glow in her eyes was brightest too. All as her body bounced up and down from his frantic thrusts, pouring the rest of his seed inside of her. And when she could no longer feel that dick of his shooting his sperm.

Chu!

She kissed him... and dropped his leash.

Thud!

“Aaauuhh..."

Fuck. Two orgasms so quick, back to back? His body was already feeling the effects of it! One would think he'd have built up a resistance after having his cock milked consistently for the week. One would be wrong. Hell, Leo himself would be wrong.

Shlorp!

“Aaah?"

Fenrir pulled up, drawing her spent pussy off of his cock. His cum spurted from her folds and streaked down his inner thigh, falling on the floor while she casually turned to face his coffee table.

Bweeeaaam!

Even with his cum in her pussy, Fenrir produced that mauve light, collecting the bounty within. Just how strong was her magical talent that she could get his cum even inside there? What else could she do with her abilities? Actually... he didn't want to know.

As Fenrir collected his cum into a magical ball, and then further compacted that ball into a bottle, Leo sat upright on the floor, watching her. His blue eyes trailed up and down her erotic backside, focusing specifically on her ass. Even through her skirt, he could see the outline of her ass thanks to how taut her gown was.

Such a peach-shaped butt. He had experienced it yesterday, but he didn't get the chance to fully appreciate it, had he? Fenrir just twerked his cock off with her underwear. And yet, he could still feel the perfection that was her backside.

And he wanted to feel more of it.

Grip! Grab!

“Hm?"

Leo's hands... reached under Fenrir's arms to grab upon her tits. In each one he squeezed her breasts, gripping them tight. The dark elf was taken aback by how fast he moved following his orgasm... but she wasn't surprised. Nor was she surprised by his thick member as it rubbed against her ass.

“Fenrir..." he whispered.

“Kufufufu! Still hard, I see~"

“Nggh... Lady Fenrir... I... haaah... I..." he swallowed his spit, “I want to... you said something before. You said... to me... that the things you could make me do, and the things you could do for me..."

“Hm? Yes?" she said with this grin that spread wider on her lips, “Do you have a request for me, Leonardo?"

He paused for a moment... and then nodded.

“Can I fuck your ass?"

The dark elf's face shifted into an expressionless visage.

Really? That's it? He just wanted to fuck her ass? Did he not realize how powerful she was? She could do more extreme things than that!

“Oh you mortals and your limited imagination," said Fenrir as she reached up to pinch his cheek, “But what can I say? Sometimes, a mistress must abide by the desires of her servants. I will grant you this pleasure."

Pulling away from Leo, Fenrir faced his couch.

Gweeeaaaam!

That bright light of hers emerged once again, surrounding her body... and then fading away. What replaced it was her nude form in all of its devilish glory. The curves, the shapes, the trim waistline, the perky bosom, the curvaceous ass; all of it! Her only clothing would be the heels on her feet, and the gloves on her hands.

Somehow, those two bits of clothing made her nudity even more erotic_._

With sweat adorning her glistening body, Fenrir walked over towards his couch and mounted it. Resting her arms and breasts upon its arm rest, the dark elf rose her ass towards Leo, taunting him with it as she shook her butt left to right. As if he needed any more goading. Even without the Piram Elixir, his cock would be as hard as titanium!

Her butt's shape was fucking perfect. The curve of it, the peach shape, the flawless skin; all of it. And there, wedged between her two cheeks was her sweltering pussy... and her tight, puckering anus.

“This way, servant," she said with that taunting sway of her ass, “The anus you crave for is awaiting you."

“Sh-shouldn't we... ya'know... l-like... use lube or something?"

Fwweeeaaaaaam!

What was that? Another usage of her magical might? But she wasn't collecting his cum, nor was she changing her clothes. Instead...

Sliiittheerrrr...

A tentacle suddenly slid along Leo's neck. He looked down at it, seeing the familiar tendril belonging to a certain kraken.

“Oh... uh... heh heh... hey... Princeton..." he whispered.

Grip!

“Oh shit!" Shove! “Ooff!?" Plap! “Nnmmph!"

With a mighty grip, that tentacle squeezed Leo, and forced him face-first into Fenrir's ass. Like her tits before, her butt cradled his face, feeling so soft, yet with this perfect level of firmness at the back. The sweat and musk between her cheeks was strongest, intoxicating Leo, and drugging him almost instantly. He even moaned against her ass, while his mouth hovered above his taint.

“Lubricant, you say?" said the dark elf as she looked over her shoulder towards his shaggy head, this wry grin on her lips, “Kufufufu! I think your tongue will be more than good enough!"

Her ass? She wanted him to lick her ass? No, not just lick it; eat it out! He'd never gone down on a girl's butt before. But with Princeton's tentacle wrapped around his neck, he wasn't given much of a choice!

It wasn't as bothersome as one would think...

“Nnmmmmmmm..."

Leo's tongue stroked along Fenrir's anus, lapping at her butt rather gingerly at first. But that first taste was phenomenal. His eyes widened as the salt of her sweat mixed with the taste of her bitter taint. Both danced on his tongue, and both coaxed him to have more.

Placing his hands on Fenrir's ass, he squeezed her butt tight, holding her in place as he deepened his rimjob. His tongue swirled around her puckering anus, licking and lapping at it, before kissing her. He was getting so into it, he hadn't realized it when Princeton's tentacle pulled away, retreating into the portal it emerged from. He no longer needed goading; he was going to eat her out all on his own.

“Mmmf! Hmmmm! Mmmmm!"

“Kufufufufu! That's it! Keep going!"

Leo's tongue pushed into her ass, spreading apart her anal walls so that he could claim deeper areas of his body. His shameless devotion to her coaxed laughs and chortles from the dark elf, who continued shaking her hips left and right to batter his head with her soft yet firm cheeks.

“See? Isn't this better?" she said, “Kufufufu! Being my little seat! It is amazing, is it not?"

He couldn't argue against her... nor could he really speak. He just ate out her ass, tasting and devouring her taint to leave it completely lathered in spit and drool. When he pulled back to breath, her ass glistened in the light of his apartment, with strings of spit hanging from his lips and tongue towards her butt.

“There... is that lubricated enough for you?" Fenrir asked, almost sarcastically.

“I... ghh...!"

Leo shook his head. It didn't really matter, did it?

Rising up further, he properly mounted Fenrir. His waist pressed up against her ass, and his cock ground along her ass crack. A few times he thrusted shallowly against her, hotdogging his cock through her butt, and moaning from the pressure of it. But as his desires continued to build, he stopped his idle foreplay, and pressed the head of his dick against her anus.

Even this slight touch – soft though it was – was enough to make Leo moan with desire.

Puuuuuuuuuuusssssshhh!

“Nnnggghh...!"

“Aaaaah~ That's it~ Kufufufufufu~"

His dick a rod of pleasure and lust, Leo penetrated Fenrir's tight ass. Her anal walls spread around his member, accommodating his enhanced girth with a similar grip to her pussy. The feeling and texture of her butt was completely different however. It wasn't as moist as her pussy, having far more grip, and was far tougher too. But that tightness? Oooooh, it was just as perfect!

Leo buried his cock all the way down to the hilt in Fenrir's taint, delving deeper inside of her until his pelvis pressed against her ass. Dropping his hands on her waist, he gripped her tight while his eyes drank in the image of her illustrious body. The way her butt fattened out into this peach shape was irresistible. He just needed to fuck it!

Slowly he drew back with his hips, dragging his cock along every inch of her ass. His enhanced dick pluck and ground against her anal walls, teasing all of them... and being teased back in return. Jolts of pleasure ran from his cock and straight up towards his brain, drawing out this deep--

“Aaaauuugghh..."

From his lips.

And Fenrir merely laughed.

“Kufufufufu!"

Gripping the couch's armrest, the dark elf began pushing her ass back against Leo's waist. Her plump butt bounced and wobbled from the impacts against his toned pelvis, jiggling straight up to her back. Even her braided ponytail bounced up and fell down!

Tightening his grip on Fenrir's waist, Leo thrusted his hips forward with a powerful--

PAT!

“GUH~!"

And Fenrir felt it.

His dick slammed into the dark elf's anus, making her head tip up and drawing this groan from her lips. It was deep, womanly, refined... and so damn erotic. Hearing it caused Leo to come to a halt... before thrusting forward with his hips once again.

PAT! PAT! PAT! PAT! PAT! PAT!

With a flurry of rushes, he slammed his cock into the Fenrir's tight anus, making her body bounce up from the powerful impacts. The rolling waves through her body caused her hair to flutter up and down... and her tits to 'Clap!' together. The couch too rocked and creaked beneath their melding bodies as Leo carved out her asshole in the shape of his throbbing dick.

Precum sputtered endlessly from the tip of his cock, drenching Fenrir's anal tunnel. As it mixed with his spit from before, it created the perfect sinful lubricant for their fucking. More and more Leo thrusted into her, growing faster with every impact. Soon that spaced out 'PAT! PAT! PAT!' shifted into a quicker--

PATPATPATPATPATPATPATPAT!!!

Leo's body – glistening with sweat – pounded his cock into Fenrir's ass with relentless, feral fervor. The sordid impacts of their bodies echoed throughout the room, mixing with his moans... and the dark elf's groans. Her sonorous and erotic voice continued to rise higher, shifting between haughty laughs, and erotic moans. She even looked over her shoulder, grinning at him, while her nails dug into his couch's rest.

But he found himself attracted to something else. He found himself locking his eyes on her ponytail.

Grab! Tug!

“GUH! Yeeeesss ~~~~! You fucking horny human beast~!"

Gripping her braided ponytail tight, Leo pulled it back, forcing Fenrir's head to tip up towards the ceiling. Her body was on full display before an invisible audience, allowing everyone to gaze upon her illustrious figure. From her clapping tits, down to her trim midsection and her bouncing ass; she hid nothing!

In fact, she grinned. Like a Cheshire cat, the dominating dark elf tugged on Leo's leash, forcing his head in close. He fell over, resting his chin on her shoulder, yet never stopped pulling on her ponytail... nor did he stop thrusting.

“I can feel it, Leonardo~" she whispered, her voice erotic and sultry, “Your manhood is swelling. Ngngghh ~~~Do it, servant~! Cum inside my tight--" GLOORRRP! “AASSSS~~~! NHAAAHAA~~~"

Within Fenrir's greedy taint, Leo's cock expanded, enlarging to a size thought impossible. From his loins burst forth an incredible torrent of jizz, one that filled out every inch of the dark elf's asshole. Nothing – absolutely nothing! – was spared as he tanked enough seed inside of her to birth a fucking nation!

Like her pussy before, his load was so great that it exploded around his dick, spreading out upon her curvy ass like the fractal lines of splintered glass. This was followed by another blast, and another, each one being just as copious and thick as the last. He wasn't just cumming inside of her, he was properly seeding her as if she really could get knocked up through her butt!

Wait... could she get knocked up through her butt? She is a demon... so maybe the rules don't apply to her? Fuck... what is he thinking? Is he even thinking?

No. Not really.

Sllllliiiiiiiiddeee! Shlo-Pop!

Leo drew back, pulling his cock from Fenrir's ass, and flinging cum as he did so. Sitting on his couch, he panted for breath like he'd run a marathon while his eyes gazed forward. Before him was the dark elf's curvy ass, his cum oozing down its peachy shape... as well as sliding out of her anus in thick rivulets. She even wiggled her hips, causing his jizz to bounce and splatter about.

Shit. If he wasn't already hard from her elixir, he would've gotten hard from that sight alone!

As her panting and chuckles simmered down, Fenrir raised her hand. That telltale 'Bweeeaaam!' sound echoed out, followed by the familiar sight of the dark elf's mauve light. It surrounded her, collecting aaaaaalllllll of that cum on her ass... as well as the seed that bubbled out of her anus.

Up in the air it floated, contained in that translucent orb of magic. Turning around, Fenrir held said orb... and like time and time before, she condensed it into a bottle that was filled to the brim.

Like... damn... how many bottles was that? Leo looked over towards his coffee table. With that, she had three bottles of mortal male seed to... do whatever it is she does with it. He didn't want to think about it. Instead, he winced... and looked down.

His dick was still hard.

“Um... L-Lady Fenrir...?" he mumbled as he looked up towards the dark elf.

He didn't see surprise, or shock, or anything like that. He saw a grin. A devilish and devious grin. A grin that spread from cheek to cheek. A grin with glowing green eyes.

She knew this was going to happen, didn't she?

“I see," said Fenrir, “It looks like I'll need to be incredibly thorough in milking you. Kufufufu! That's fine. I'll receive all of my payment in due time."

Was he being played? Was she hustling him? He hadn't even been tutored yet today!

Damn demon. Her knowledge may be invaluable, but the things she was doing to his body was nothing short of cruel. Making matters worse, he found himself incapable of denying her. While he knew he was being toyed with and steadily drained of all the semen stored in his balls, there was nothing he could do about it. He wanted, if not demanded more.

He needed more.

So when Fenrir gave a tug to his leash...

Tug! Shlink!

“Nggh...!"

“Are you ready, servant?"

Leo sheepishly nodded.

“Yeah, yeah... let's just... get this over with..."

Tug! Shling!

…

Spotless. His couch and living room were completely spotless: free of cum in any form. If you were to come in here, you'd never know that a lot of fucking just went on behind these walls. You'd instead think its owner had a furious workout session due to how sweaty and stuffy it was here.

But then you'd take a whiff of the room, and you wouldn't just smell sweat. The cum may not be here, but the odor of it continued to permeate the air. It would choke you unconscious before you took one step inside! And if the smell wasn't evidence enough of what went on in this room, then the near dozen bottles of sperm that sat on the coffee table certainly was!

In all of her nude glory, Lady Fenrir stood at the back of his apartment, gazing out of the window. Outside was a nearby railroad, one suspended in the air via a bridge. It was dripping with water, as from the skies fell a downpour of rain. And yet the trains continued to run, sending its rumbles throughout the apartment.

It was later in the evening now following their hours of heated fucking. And after those heated hours...

“I can barely move..."

“Stop. Whining."

“Tch! That's easy for you to say! You're like some... guh... nympho goddess or something..."

She looked over. Sitting on his desk, a near husk of a man, was Leonardo Gracey. His body was pale, his flesh slightly sunken, his teeth rattled... and his dick flaccid. He was also completely naked; why bother putting on clothes following what they went through?

Making matters worse, their furious fuck fest was followed by a furious study season. Truly, he pissed off God when he decided to summon a fucking demon!

“Okay...." mumbled Leo as he leaned back in his chair, “I finished the velocity equation..." he looked up, “Is... it right...?"

Fenrir turned and walked over to him, where she bent over to check his work. Her emerald eyes – perceptive and intense – scrutinized every inch of his paper, reading all of his notes and deciphering it all. He expected her to tell him he was wrong and to start berating him... but he knew she wouldn't. Why? Because he already knew...

“Correct, Leo..."

That he was right.

A sigh of relief left Leonardo as he leaned back in his chair. Smiling from cheek to cheek, he felt more informed of his mathematical talent than ever before. Eeeh... maybe calling it mathematical 'talent' was a bit of a stretch. He couldn't even say he had mathematical prowess. He was just... mathematically competent.

Yeah. That sounded good. Mathematically competent.

Fenrir continued to brush her palm along his notes, making absolutely sure that he didn't make any mistakes. But after a week of solid grilling and studying, he had finally – finally – understood the importance of constant integration! It brought a smile to her face!

But with this solved problem, there came a realization. The final material covered in his textbook – as well as the final materials covered in class – were based on velocity and acceleration. If he was solving problems with relative ease now on the final assignments, then...

“Ufh... haaah..."

Raising her hands, Fenrir placed them into her hair, where she tossed it up – once, twice, thrice. A relaxed groan left her lips as well, as if she was letting something free from her shoulders. Leo knew what was about to leave her lips, and – for some reason – it left him feeling... perplexed. He both wanted to hear those inevitable words, and didn't want to hear them. Because when she said them – when she said what they both knew she was going to say...

“With this, I'd say our time together has concluded..."

He knew there was no going back.

Leo stumbled upon hearing her words... before giving a sigh of acceptance... and disappointment. Even though it had only been a week – just six days in fact – of knowing her, he already felt like she had become a fixture in his life. No longer seeing her would be...

“Aah..."

“Don't make that face," said Fenrir as she placed her fist on her hip, “You should be thankful. I no longer have to milk you like some breeding stud."

“I-I know..." he muttered... before shrugging his shoulders, “But... ya'know... what if I kinda... liked it...?"

Fenrir leered at him upon his statement, this taunting chuckle leaving her lips.

“You mortals. Such slaves to lust and pleasure."

He opened his mouth to make a counterargument... but instead he smiled, chuckled, and nodded. Yeah. He was, wasn't he? As shameless as it was to say, he did enjoy the sex with her. He'd be a lying fuck if he claimed otherwise.

But that didn't change the fact that – the next time Fenrir walked through her door and returned to Daemonium – they may likely never see each other again. He couldn't call her, couldn't talk to her, couldn't even see her; never again. If he wanted to say something to her – to ask her anything – this was the time to do it. So... he said the first thing that came to mind.

“Fenrir..." he whispered, making her tilt her head at him, “What...what is Daemonium like?"

“Tch... you ask that now?" she replied in an incredulous manner, making him shrug his shoulders.

“Well... why not now?" he asked back, “I don't know if I'll ever see you again. I may not ever get the chance to ask this."

“Oh Leo..."

Her lips curling into a cat-like smile, the dark elf walked up to him with her hips swaying from side to side. For a moment she thought about his question, pondering what she should say, and if she should say anything. Instead, she raised her hand, placed it on his cheek, and guided him in towards her.

Chu~

Briefly, they shared a passionate kiss. She held their lips together for a few moments, drawing out the kiss for seconds at a time. All the world around them seemed to stop mattering. Even the rain against the walls didn't reach them.

But what felt like forever was only a few moments. The two parted, with Leo looking into Fenrir's emerald eyes.

“Some things are better not knowing."

That was the worst kind of answer: A none answer. But... it was an answer nonetheless... and Leonardo accepted it. Yes. It was probably better off not knowing what demons do in a realm full of them. He barely survived dealing with one demon who was teaching him math!

Fenrir drew back, and turned to face the empty space in his living room. Like time and time before, her sinister door emerged from the floor, casting its looming shadow throughout his apartment. Still naked save for her gloves and heels, the dark elf walked over towards his coffee table, where – with the use of her magic – she picked up those many, many bottles of cum. They vanished into thin air, no doubt placed... wherever it was she put them when they disappeared. She then walked over towards her door, opening it up to reveal that gateway of darkness on the other end.

Placing her hand on the door's edge, Fenrir came to a halt for a moment. She took in a deep breath as the shadows within blew past her, then turned to face Leonardo one last time.

“Take care of yourself, servant," she said, “And... food for thought: The next time you need tutelage, save up money to hire a real tutor, instead of turning to sorcery to summon a demon. Other demons may not be as forgiving as I."

“I get it, Lady Fenrir, I get it," he replied with a hapless smile.

“Oh. And one last thing..." she walked into the doorway, “Lose my number. If you summon me again, I will steal your soul."

“I...? Wait… What...? Seriously!?"

Eeeeeaaaarrrk!

THUD!

Fenrir's door slammed shut, refusing to elaborate any further. It sent a cold chill down Leonardo's spine, and made him take a deep breath. For a moment, he pondered if she was being serious, or telling a lie. After all the time they shared together, would she really steal his soul?

Yes. Most likely. At the very least, he wasn't keen on finding out!

As Fenrir's door sank into this floor, she left this world... and returned Leo's life to (relative) normalcy. It was Saturday night now, meaning he had all of Sunday off to do whatever it is he wanted to do before Monday's exam. And he knew how he was going to spend Sunday.

Studying.

First things first though... he needed a bottle of water!

…

Galendale University. It was a college as old as Willington itself. It is said that when the city was first erected in the early 1800s, that Galendale University was one of the first structures built. A college where people from all across the country would come to study at, in order to learn law. Many brilliant judges, lawyers, defense attorneys, and much more have come in and out of these gates. And he would be one of them.

Leo walked through the front gates of the college campus, heading down the main lane towards the front doors. Beside him were the many other members of the alumni, all coming and going. He was just another among many... even if he was sweating slightly harder than everyone else.

He was worried, his body anxious to a degree that made it difficult to think. While he felt confident when he left his apartment earlier that morning, that confidence waned further and further with each passing moment. By the time he entered the halls of the university proper, his heart was beating furiously in his chest!

Trekking down these familiar halls suddenly felt ten-times more difficult; almost like cement was in his shoes. His limbs were weighed down, and all of reality felt like it was slowing down. And yet, he continued on nonetheless, pushing himself until--

“Oh... Mr. Gracey, you're here early."

“Ah! M-Ms. Hayes! I mean Mrs. Hayes! I-I mean Professor Hayes!"

Before him was the familiar sight of an older woman with black hair and tired brown eyes behind glasses. Wearing business formal, she was unlocking the door to her classroom, while her problem student stood before him.

“I hope your punctuality means you're going to take this exam seriously," said Prof. Hayes with a sigh as the door swung open, “I don't think I need to remind you how important passing this exam is."

“Yes. I know... I remember well..." said Leo as he exhaled deeply.

“Good."

Entering into the classroom behind Prof. Hayes, Leo sat down at his spot, where he took another deep breath. Anxiety was nipping at him, and his composure was shaking. But as he took out his books and notes, he opened them up to reveal the hundreds of pages he created while under Fenrir's tutelage. Seeing them not only calmed him down, but instilled a sense of confidence within him.

As the minutes ticked by, the classroom was steadily filled out by his fellow classmates. Leonardo straightened up and took another deep breath, steeling his nerves. When everyone arrived, Prof. Hayes addressed the class, but her words were deaf to him. He sat there, waiting for the inevitable arrival of...

This paper...

Here it was; the exam that dictated his future. Before him sat a plethora of pages asking various numerical questions that he needed to solve correctly. A week ago, this would have been insurmountable. Today, it was manageable.

He would not fail this test. Not just for his sake, but for Fenrir's sake as well.

He could not let her down.

He could do this. He could do this.

It was time to get to work.
