Immoral Fruit

"Haaa... Daaaddyy...! Aahhh..."

It was happening again tonight. It was happening again. It was happening again.

It was happening again.

Her long tongue slicked along his throbbing dick, hot breaths flowing form her mouth to pepper along his length. It throbbed in her hold, while the hot, gooey strands of her spit and his pre hung between them like a bridge of lust.

She was a teenage girl, one just on the cusp of young adulthood at the age of seventeen or eighteen-years-old. Flaming red, orange, and yellow hair hung down to her shoulders, and her eyes were a most beautiful green. Freckles laid upon her face too, dotting along her cheeks while her lips were curled into a saucy grin. A saucy grin that flashed her fangs that is.

The girl was a bat, one with mocha-brown fur but such vibrant red hair. She had the disposition and figure of a tomboy, what with her short hair and athletic build, though her wingspan was rather impressive. However, said wings were closed in as she sat on her knees before the cock of her much, much older lover.

A grown man. Brown fur too, though he didn't appear to be a bat like she was. No, he was a... wolf. Brown eyes, but with a more studious look to him. He didn't appear to be dangerous like many a wolves would have you believe. No, he was softer, kinder, more mature and suave...

While a teenage girl sucked his dick.

He groaned as he gripped the cushions of the couch beneath him, body shuddering with pleasure. His sensitive dick was held captive by the redhead between his legs, who gently stroked his cock up and down. Such a cute, sexy, taunting girl, one who indulged in the sordid act as her grinning lips showed. Breathing so harshly upon his cock, she extended her tongue to lick upon the side of his cock, causing yet another moan to flow from his lips.

"Haaaa... nnnghhh! A-Amelia... haaaa!" he groaned, his length throbbing so headily along her face, "C-calm down..."

But she shook her head, giggled too. Flashing her cute little fangs at the man before her, she instead used her long tongue to lick his cock from the base of his knot, all the way up to the top of his lupine dick. A giggle slipped from her mouth soon after, enjoying every moment of her sordid display before positioning her head right above his throbbing cock.

"Now why would I do that, Daddy?" she asked, eyebrow raised as her ear even twitched, "Heh heh! I don't think you're going to go down any time soon by yourself, after all... heh heh!"

She enjoyed this, that much was clear to him. And due to his sudden hesitance, the young bat girl gave a teasing laugh. Reaching up, she grabbed the wolf by his broad shoulders, squeezing tight to pull herself up and over to him. Legs parted by his waist, the bat straddled the hips of the older man while her green eyes peered deep into his brown ones.

"Daddy..." she whispered breathlessly, one of her hands reaching down to grip the hem of her nightgown, "Haaa... I'm so wet, Daddy... nnghh! I'm so wet..."

Gently pulling up her gown's edge, the teenage bat flaunted her lower half to the man before her. So toned, so athletic, and with a pussy that was so wet. A shiver ran through her body when the cold touch of the air around them graced her form, but that didn't stop her from grinning so seductively to the wolf she sat upon.

"Daddy..." she whispered, her wings gently pulling in, "Haaa... please... Daddy..."

He bit his bottom lip at the sight, saying nothing as his brown eyes drank in the image of her. One of his hands then reached up and over, one to grab her thigh and ass, squeezing it and garnering a moan from her. The other reached up to her face, gently cupping it in his palm, stroking it, and just marveling at her like some beautiful diamond.

The grinning face of this girl... oooh... it made his cock so hard.

Following the wolf's guidance, the bat started moving down, impaling herself upon his thick, girthy cock. Every inch of her pussy was claimed by his lupine dick, one that triggered a loud, breathy moan from deep within. It filled the air, though she quickly clamped her mouth shut to stifle her moans.

It didn't work too well.

"Nnnnghhh! Daddy!" she groaned through gritted teeth, "Haaaah! It's so... big!"

Together they moved her down, not stopping until the redhead sat firmly on his waist. When she felt his knot teasing the entrance to her pussy, she knew it was time to stop. They couldn't force it all in her, not in one go, and not yet. No, no, it would come soon, that much is true. But until then...

"Mmmfff..."

"Mmmm... narrrl... mmm..."

A heated, sordid kiss suddenly met between them, lips crashing into lips and tongues dancing alongside tongues. They were so lurid and so fast, swapping spit so lustfully before they finally pulled back. The wolf - now desiring her just as much as she desired him - kissed away from the bats lips, instead moving down to kiss upon her cheek, then from her cheek to her chin, and from her chin to her neck. Each kissed caused the redhead's moans to grow louder, her tail wagging frenetically with such untamed arousal. That's when his hand slipped under her dress, moving up to grab one of her tits into his palm, giving it such a tight squeeze. The teenage bat moaned from the feeling, while the gruff digits of the wolf pinched upon her rock-hard nipple.

"Haaaa... damn... fuck... please," she groaned, "Aah... s-start moving..."

His hand on her thigh shifted, sliding around to the curvature of her ass where he gripped it tightly. Moaning, the wolf began to lift the taunting bat up, her cunt stroking along the fullness of his length before he pulled her back down. The impact was weighty, sending a soft jiggle of her ass that ran up to her breasts and hair, as well as a moan that flowed from her lips. The taunting teen eventually swept her eyes back down to the older man who fucked her, flashing him his fangs while he gave a slight grunt.

Up and down he began to thrust, sliding his dick into her tight pussy. She clamped down on him, holding him deep inside of her warm and wet tunnel, not truly wanting to let go. His thrusts were great however, and each one made her breasts bounce and ass clap. All the while, lustful, deep moans flowed from her open mouth, and her cute wings fluttered without control.

The sordid pleasure the two partook in kept building and building, the wolf's dick throbbing in her cunt, and her pussy clenching and tightening around every inch of it. Moans escaped from the both of them, building higher and higher, filling out the living room and drowning out over everything else. The wolf's claws extended, scratching lines upon the ass of his much lover younger, while her hands gripped harder at his shoulders. She started moving her hips faster as well, pushing her juicy ass back down against his waist, building their lusts higher and higher.

"Haaa! Haaaa! Daaaddyyyy!" the redhead moaned, "Aahh! Oooohhh!"

"Nnngh! Amelia," he moaned back, his being deeper and more guttural, "Haa! Haaa! Nnnhh!"

Soft yet strong patting noises echoed out, bouncing off the walls as they continued fucking on the family couch. His cock soon started throbbing within her in such a new, unique manner. She recognized the feeling, recognized the hardness, recognized... all of it. It just kept building, higher and higher until...

"GAAHHHAH!?"

Every time it slipped inside of her, it always took her off guard. With one thrust, he slammed every inch of his dick inside of her, knot included. And once it did, the bulbous sack grew almost twice in size, locking the two in place so that escape was impossible. They sat there, locked together tightly, escape impossible for either of them, before finally...

"Hooohhh!"

"Haaaahhh!"

Wings fluttering about softly, she felt the wolf shooting his seed deep inside of her pussy, filling her to the brim with his spunk. The duo let out combined moans as they did so, while his knot kept them bound without any chance of escape. Her orgasm came shortly after, teeth biting into her bottom lip as such thick, clear, feminine juices squirted from her cunt, surrounding the wolf's cock. The two then rode out their orgasms, moaning as their bodies leaned in to press against one another. And when they did, the green eyes of the bat on his waist peered deep into his brown ones. There was no hesitation on either of their parts.

"Mmm..."

"Mmmfff!"

Hungrily they began kissing one another, swapping spit and tongues whilst cradling each other in their arms. Hey, it's not like they were going anywhere any time soon with that knot keeping them bound; might as well enjoy it for as long as they can.

What the two didn't know however, was that they were being watched._Eyes peered at them from over the edge of the staircase wall, having seen the sordid act of them fucking on the couch. They were wide, having observed every moment between the two lovers. But that's just the thing; they _weren't lovers. They weren't even remotely close to being lovers.

They were her family. That was not some man and some teenage bat, no, that was her father and sister. They were father_and _daughter. And tonight, like many a night now, she had caught them amid a midnight tryst.

"Haaa... haaa... ooooh... Daddy..." said the redhead, a giggle slipping from her lips soon after, "Heh heh... are you ready for round two?"

"Hmm... just keep it down," he replied, "We don't wanna wake up Cassandra..."

"Shhh... it's okay... what she doesn't know won't hurt her..."

Little did they know that she was more than aware of their current situation.

...

"Hey pops! What's for breakfast today?"

"Uhh... pancakes? Like usual?"

"Ugh! So lame!"

She walked into the kitchen with that trademark grin on her lips, fiery-red hair bouncing up and down as she jaunted inside. Like usual on this weekday morning, she was wearing her school's uniform rather haphazardly upon her body. The green skirt was sloppily eschewed, the blouse undone at the top to flaunt a bit of her cleavage, and her jacket laid a bit off of her shoulders. It was a very lax way to dress, just to put it lightly, but it didn't go unnoticed by her father.

Matthew Morris was a tall wolf, brown fur, brown eyes, and always dressed to impressive. Whenever you saw him, he'd be wearing some sort of formal clothing, like a business man out on his coffee break. Being a wolf, he always looked rather serious and stern, but he only got that way around his twin daughters. Otherwise, he was known as being intelligent, kind, and quite the charmer.

Ah... but we're getting a bit out of hand here.

Matt and his daughters lived a simple life in a place known as Blue Ridge; a lakeside community that was a good half an hour or so drive to the nearest city. It was also known as being a virtual hub for affluent business men to live at, if all the luxury boats and yachts out in the lake are anything to go by. The Morris family were - by comparison - far more modest, lacking a yacht or boat of any kind.

It's not like Matt can drive one anyway...

"Hey, where's your sister at?" Matt asked as he looked at his daughter, even performing a casual flip of a pancake whilst doing so.

"Hmm... I ran into Cass on my way downstairs... she was taking a bit longer than usual," the redheaded bat replied with a shrug of her shoulders, "She'll probably be here in a few sec--" tap!"conds...?"

Turning around, the two turned to face the entrance to the kitchen, their eyes falling on another bat who had entered the area.

She was a teenage bat just on the cusp of adulthood, somewhere along the ages of seventeen or eighteen, and much like the redhead, she was wearing her school's uniform. But where as the redheaded bat was dressed more slack and casually, this bat was dressed more conservatively. Her skirt was appropriately fixed to her body, her blouse buttoned up neatly, and her blazer rested on her shoulders firmly whilst also being zipped up.

Also much like the redhead, her fur was brown, though her hair was jet black and ever so long. It fell along her back, nearly touching her tail in fact. A shorter girl, she was known as being small and cute, with a rubenesque figure. Heh, some would call her 'thicc'... and honestly, she has no idea what 'thicc' even means.

Her name was Cassandra Morris, and she was always seen as being quiet, shy, and demure, with a personality more in line with her father's. It was in complete opposition to her sister's personality, who was fiery, feisty, adventurous, and ever so much the typical 'bad girl'. Their differences in nature was so extreme, that whenever people met the Morris sisters, the first thing they'd often ask is always the same.

Wait, you two are twins?

Yeah, the spunky, talkative blonde bat who often dyed her hair red, and the quiet, reserved, bat with black hair, were in fact twin sisters. And who is that redhead bat, you may ask? Why, her name was--

"Amelia..." said Cassandra as she looked at her twin, before sweeping her eyes over towards the wolf, "Daddy. Were you two talking about me?"

"What? Us? No way!" Amelia replied as she shrugged her shoulders in a cool manner, "Dad was just asking about you, is all. He was worried about his little sweet daddy's girl!"

"Huughh... Amelia..." Matt muttered, eyes rolling at her teasing words. Eventually those eyes settled on Cassandra, where he gave her a kind smile, "Good morning, sweetie. Did you sleep well last night?"

"Y-yes, of course," the young bat replied with a smile, "It was a... lovely sleep."

"Ugh... 'it was a lovely sleep'! Like, who even says that?" Amelia remarked in a snarky manner.

"Ameliaaaaaa..." Matt groaned.

Mornings like this among the Morris family were the typical sort on school days. Their father would cook them breakfast, then they'd drive off to school. It's how their life had been since they were little girls.

Though for Cassandra, it was a bit harder seeing her family as just her_family_. Considering what she had witnessed the previous night - and many other nights at that - seeing them talk so casually like father and daughter was just so... bizarre. Here were two people who - just the previous night - were fucking on the couch like a pair of randy teenagers. And they were father and daughter no less!

But right now, they were speaking as if it was just any other calm, Tuesday morning. Haa...

Cassandra's stomach had begun tossing and turning because of this. They were sick and disgusting, fucking behind her back like animals, regardless of their relation to one another. But more importantly, they did so in spite of her feelings on the situation. They were hiding it from her, and that - for whatever reason - hurt Cassandra more than the act itself.

She always saw herself as their father's favorite. Hell - of the two of them - she was the 'Daddy's Girl'. But it was Amelia who he chose. And it's not like it was an age thing; they were twins! They were the same age! And--

Why did this make her so jealous!?

"Uhh... Cass? You okay there?" Amelia asked, causing the bat to give a slight hop in place.

"Ah? Oh! Y-yes! I'm fine!" she said with a soft squeak, "I'm fine! P-promise!"

Both Amelia and Matt traded glances with one another briefly, before shrugging off Cassandra's little moment. Instead the wolf went back to cooking their breakfast, while Amelia pulled out her phone to start fiddling with it. Sitting at their table, she casually brought up a video to watch, while Cassandra remained standing for a few moments. Eventually she joined her sister at the table, though she didn't say anything to her.

Amelia's green eyes darted between the two, processing the information she had as she had done so many, many times. To know that they were fucking behind her back was like taking a dagger to the heart. Made even worse by the fact that they played it off as if it were nothing. Not once since she first learned of them doing this has she seen either of them act weird or out of character. How did they pull it off so well?

It all happened accidentally at first, obviously enough. Cassandra awoke in the night one day, with desperate need to use the bathroom. But when she exited her bedroom and entered the halls, she heard faint moans echoing through the floor board. Curious to the sound, she soon discovered that her sister's bedroom door was open, and she was not inside. Naturally, Cassandra thought that Amelia was sick, and was downstairs to take medicine. And being the ever helpful sister she was, the demure bat went downstairs to help her sibling out.

What she discovered instead still replays in her mind to this day.

The image of her father, sitting down at his chair, whilst having his cock sucked by his own daughter. She remembered the lustful moans Amelia and Matt gave that night, as well as the image of the back of her sister's head as it bobbed up and down on their father's cock. Even the lustful faces her father had on were still prevalent in her mind, remembering them as if they happened yesterday.

Then again, we already know what they did yesterday, don't we?

For the longest time, Cassandra thought it nothing more than a truly strange, bizarre dream. Her father and sister having sex? Yeah right! Her father was the most sensible, law-abiding man she had ever met; she couldn't imagine him having one-night stands, let alone having his dick sucked by his own daughter. And even Amelia - with how adventurous she could be - would never have sex with their dad! It was disgusting!

So yes, it had to be a dream, right?

No.

She went by months before the same thing happened. She awoke one day at night to the sound of faint moans, headed downstairs, and saw an even more sordid sight. The image of their father Matt, fucking Amelia on the couch, while her whorish moans echoed into the air. That would be the first time she saw them having full on sex, and the realization that her father and sister were indeed having a sexual relationship behind her back.

Every now and then, she'd catch them in the act, but would never have the courage to outright confront them either during it or after it. The location would change, be they in the living room, their father's room, or even Amelia's room. Regardless, the sexual sounds of their voices would taunt and leer at Cassandra all through the night.

And through the day.

"Eyes up! Breakfast is served!" said Matt in his coy and cool manner as he placed a plate of food on both of their sides.

"Ah! Sweet! Thanks, Daddy!" Amelia said, excited by the pancakes and bacon they were served with.

"Hey, hey! Calm down!" he warned whilst laying their hot plates before them, "Stop moving so much!"

Watching their banter back and forth caused Cassandra's stomach to toss and turn. Doubly so when she heard Amelia call their father 'Daddy'. When it came to the two, it was Cassandra herself who called him 'Daddy'. Amelia usually went with some other affectionate name, like 'Dad' or 'Pops' or even the rare 'old man'. The only time when she called him Daddy...

Was in the throes of passion.

It was hard to tell if Amelia called him Daddy due to a mere slip of tongue, or a purposeful action to tease what was going on between them. Regardless, neither she nor Matt brought any attention to it, playing it off as if it were nothing.

Haaa... it made Cassandra sick to her stomach.

How could they act so calm, act coy, act like father and daughter when they were clearly not a normal father and daughter? Inwardly, Cassandra was angry with them, but outwardly, the demure and shy bat continued acting as if everything was normal.

"So what are you going to do today, pops?" asked Amelia as their father removed his mittens.

"Uhh... the same I always do," he responded in a casual, blasé manner, "Those hotels of ours aren't going to run themselves, sweetie..." he then raised an eyebrow, "And what of you, hm? I've seen your English grades, Amelia."

"Oh, heh heh, you have?" she said with an embarrassed blush whilst trying to shrug things off, "Hey, i-it's okay, pops! I swear! Heh heh! Just uh... d-don't think too much about it, okay? I've got English in the bag!" then in some attempt at changing the topic, she shifted her eyes over to her twin, "H-hey, Cass! What about you, hm? Everything's going great, right?"

Both of their eyes fell on her together, causing Cassandra to tense up as she was put on the spot. Having them both stare at her felt so strange, bizarre and uncomfortable, and for quite obvious reasons. She hesitated mid bite whilst looking at them, wings and tail giving a slight twitch as she didn't know what to say.

"Uh... n-nothing's wrong with me," Cassandra replied, even giving a sheepish chuckle to play it off, "Just... uh... schoolwork as usual."

"And unlike your sister, your grades are perfect, sweetie," Matthew stated a he reached over to his daughter, placing his hand behind her head and scratching it.

Feeling his gruff claw scratching ever so softly along her ear was always a surefire way to melt Cassandra's heart. Whether she be a teenager such as now, or a child in her youth, that gesture was always enough to make her smile.

Well...usually.

As he scratched at her ear, Cassandra's eyes fell on Amelia. And her twin was just... smiling at her. And for some reason, that normally cheeky grin her sister always gave felt as venomous as poison. Seeing it caused Cassandra to pull way, face grimacing and her green eyes immediately returning to the plate before her. Fortunately for her, Matt didn't seem to notice. Instead he sat between them as he usually did, more than ready to enjoy his own breakfast.

Casually, Amelia and Matthew began to talking to one another, but about what, it went over Cassandra's head. No no, she was more interested in their mannerisms, and less interested in their worlds. They were acting their usual selves... but leave it to Amelia to act _too_flirty at moments.

The way she leaned over the table some times, as if to flaunt her breasts to their father. Those gleaming, gazing, green eyes and how they fluttered into such sensual glares. Her wiggling hips and ass whenever she leaned over in the table almost too far, that wagging tail to show her elation, and especially that tone of voice that sounded a bit... lustful. Ohh, it all made Cassandra groan.

And Amelia wasn't making things any easier.

"Haaa... it's gonna get hotter today, Daddy," Cassandra overheard her twin say, "I think I'll take a dip in the pool after school. If you don't mind, that is."

"Aren't you too old to be worry about such things?" Matthew muttered in reply with a roll of his eyes, "You and Cassandra are seniors now; I think you should be more focused on college entry papers and the like, more so than any pool."

"Oh Dad, you're no fun!"

Gleefully flaunting off the fact that she was going to go to the pool after school; what daughter does such a thing with their father? Just hearing Amelia's brazen words were enough to make Cassandra's blood boil. Her twin was always the more adventurous of the duo, but she was taking things too far!

But it wasn't like Cassandra had the galls to do anything about it. If anything, it just made her lose her appetite, leaving half of her pancakes still intact and some of her bacon strips as well.

"Nnngh... I... I've got to use the bathroom," Cassandra even muttered as she pushed herself away from the table, leaving her sister and father confused.

"Is... everything okay, Cassandra?" Matt asked, concern for his daughter obvious in his voice.

"Y-yes," she lied, "Everything's fine. I just... hm... I'm just not too hungry..."

Leaving the dining room, she left both Matt and Amelia rather perplexed by her shift in demeanor. Cassandra however stopped at the wall right beside the dining room, lingering there for a few more moments. Whenever she closed her eyes, all she could think about were her father and sister having sex. As one may expect, casually having breakfast with the two of them was no longer as easy as it once was. Not made any easier when Amelia insisted on flaunting herself to her father, even going as far as to call him 'Daddy' like she did at night.

And like she did on many nights.

"Hey Cass."

"AH!?"

Hopping forward, the black-haired bat turned around to face her twin sister. Amelia was taken aback by how her sibling leaped forward, the two mutually shocking one another. But the redhead being ever so feisty easily took to the situation, grinning as she reached her hand out to place it upon her twin's shoulder.

"Everything okay, Cass?" she asked, eyebrow raised, "You were acting a bit off during breakfast..."

"E-everything's fine," Cassandra lied yet again, "Wh-where's daddy?"

"Hm? Oh, cleaning the dishes, you know," she answered with a shrug of her shoulders, "But what about you? It's not like you to leave dad's pancakes behind."

Ugh, listen to her; 'leave dad's pancakes behind'. Just call him 'Daddy', you little hussy! At least, that's what Cassandra wanted to say, but being the docile bat she was, she remained silent.

"I just... wasn't hungry, okay?" she muttered before gesturing down the hall with her head, "Sh-shouldn't we be going to school now? Y-you're driving, right?"

"Ugh, I'm always driving," Amelia replied with a roll of her eyes, having seemingly dropped the earlier conversation, "Welp, let's go Cass! The sooner we deal with these next seven hours or whatever, the sooner we can get back home."

Yeah, get through it all, so you can get back to Daddy. Ugh... it made her sick.

Pushing by Amelia, Cassandra made her way upstairs so that she could collect her backpack and other things. In doing so, she left the redhead a bit shaken, though she didn't say anything. No, no, Amelia just looked at Cassandra, watching her walk off...

A low chuckle slipped from her lips.

...

Why were they doing this? It was a question that kept Cassandra up at night, despite her attempts to think otherwise. Were they just that horny, was that it? If so... then why with each other? While Cassandra wasn't the type to think about her family's sex life (seriously, who does that?), she couldn't help but to think there were other candidates out there for them both to be with. How many boys at school would jump at the chance to be with Amelia, and Cassandra was sure their father had plenty women at his job who'd love to be with him. So... why each other?

And why not her?

Tugging on her over sized stuffed dolphin, Cassandra stared up to the ceiling overhead. It was nighttime now, the school day over, the lights were off in her house, and honestly, she should have been a sleep an hour or so ago. Amelia was the one who liked to stay up late; Cassandra, not so much.

But as of late, she has been finding it harder and harder to sleep at night, and for obvious reasons. Her mind was often wondering if her father and Amelia were currently together right now. Whenever her eyes closed shut, she just imagined her twin in some new position, having that thick, lupine cock pushing into her pussy. Or on the other hand, her sucking on her father's dick, bringing him to climax. Such sordid images, and they never left her mind.

Not for a moment.

But in truth, Cassandra wanted to know why? Why Amelia and not_her?_

Getting up from her bed and leaving her stuffed dolphin behind, Cassandra slowly made her way over towards her vanity mirror. Gingerly her hand reached out for the desk lamp resting on it, bringing life to her bedroom so that she could see herself.

What she saw staring back was not an ugly girl... right? Sure, she wasn't as tall as Amelia was - being a few inches shorter - but that wasn't too bad. Cassandra knew that her breasts were bigger for one thing, and she had bigger hips as well. Boys like that, right? Then again, her waist wasn't as thin as Amelia's waist was, and honestly, her twin was skinnier than her overall, having a more tomboyish and athletic figure. Hey, Amelia used to be apart of the school's basketball team, while Cassandra excelled in the book club; there were bound to be differences.

Was that why her father chose Amelia over her? Was it because she was just... boring? Cassandra wasn't the most courageous or adventurous girl out there. Hey, can any daddy's girl be considered those things? Perhaps... perhaps not. At the end of the day, those weren't words she'd use to describe herself. No, she was more like her father: bookish, silent, calm, and demure.

Lacking her sister's boisterous attitude, Cassandra thought that her father would prefer that. They were a lot more alike, after all. Maybe it was her body...

Frowning, Cassandra looked down to her chest as it strained against her pink pajama blouse, her fingers reaching up to grip at her two orbs. Gently she began to grope herself, wondering if her father would find this aspect of her body pleasing. Maybe she should wear tighter shirts, flaunt her so-called 'thicc' figure more. And maybe she should wiggle her hips more too, try and taunt and tease her father, like Amelia did. Then maybe, maybe, just maybe, he would...

Would...

What the hell was thinking about!?

Pulling back from her vanity dresser, Cassandra struggled to realize just what was going through her mind. Her and... Daddy? No, no, she shouldn't have such thoughts; that was disgusting! She wasn't jealous! No, no sirree! Nope! Not at all!...

But... it still hurt.

It hurt knowing that her family was doing this behind her back. It hurt knowing that they'd do it in the first place, and it hurt knowing that they'd keep it a secret from her. She needed to confront them about it. She needed to yell at them about it. She needed to do something! She needed to... to...

"Haaaaa..."

Cassandra's green eyes grew wide, her head turning to face the wall behind her. It was a voice, one echoing through the walls of her home and coming from the direction of her father's room. When she heard it, the bat began to fidget a bit in place, worried by the implications of such a thing.

They were doing it again.

Slowly making way over towards her bed, Cassandra crawled inside in some vain attempt at ignoring them. Perhaps if she closed her eyes really, really hard, and put her pillow over her head, she'd be able to ignore their voices.

But...

"Nhaaaaa... daadddy..."

How could she sleep when her sensitive ears picked all of that up? They did know she was a bat, right? She could hear damn-near everything! And while they used to do a good enough job of keeping quiet, that was no longer the case.

It was like a ghost, haunting her, taunting her, beckoning her forward. And without fail, Cassandra fell for it every time.

Getting up from her bed, the young bat held her stuffed dolphin close as she inched her way towards the door. The sensual moans she heard had faded by now, but she knew it was only temporary. Sooner or later, those lustful voices would return, and louder too.

Nevertheless, Cassandra exited her bedroom ever so silently. Her father's room was the last room in the hall, right before his private study that is. Approaching it slowly, she made sure to keep her voice as low as possible as her slippers silently strode along the rugged floors. Closer and closer she came to her father's room, with those lewd sounds getting even louder.

"Mmmm... mmmm... haaa... haaaa... mmmm..."

The door was slightly open.

Lurid kisses echoed through the bedroom, lips pressing to lips. She clutched close to the broad body before her, hands resting on his chest while he wrapped an arm around her thin waist. Being pulled in, the teenage bat gave a shuddering moan as her breasts pressed up to the flat chest of the man she was with, while their lips parted so that they could breath.

"Haaaa... Daddy," Amelia moaned, green eyes glowing as she looked up towards his brown ones, "Mmmm... I can taste the scotch on your tongue. Heh heh... I hope you didn't drink before driving home today."

"I didn't have too much," he replied, head shaking before he glanced away briefly, "You know I don't drink and drive..."

"Of course, Daddy," Amelia replied in a teasing manner as she flashed him her fangs, "My father is soooo responsible!"

Yeah right; 'my father is soooo responsible', she says as he's currently making out with his daughter. The statement was so perfect, so, how you say, 'meta', that Cassandra was sure it was purposefully directed towards her.

The demure twin lingered outside the doorway, green eyes peering through its small gap towards the two. Amelia was resting atop her father, keeping him pinned beneath her smaller body as her green eyes looked into his face. Her lips were curled into such a saucy grin, while he looked back up at her with that typical aloof gaze of his. His glasses were still on his face however, coaxing her to remove it by the tiny bridge in the middle.

"And... there," Amelia said as she placed them aside, "Do I look sexier without your glasses on, Daddy?"

"Ameliaaaa," he groaned with a roll of his eyes.

"Just wondering..." quipped the bat, her hands giving his shoulders a gentle squeeze, "Why don't you lay back and relax, hm? Let me help you unwind, Daddy."

He was still dressed in his formal business clothes, while she was wearing her silky nightgown. Heh, ironic that she was the nightgown-wearing type of girl, while Cassandra preferred her pajamas, but that's neither here nor there.

No, right now, the redheaded bat started moving her way down towards her father's waist, her hands tugging a bit at his pant's belt buckle. Undoing it rather quickly, she loosened its hold on his body, allowing her to pull his gray slacks down his knees. And once she did, she saw the massive bulge in his underwear, causing her wings to flutter as a giggle flowed through her grinning lips.

"Heh heh! You look really hard, Daddy!" Amelia said, "Did you miss me that much?"

"Haaa... well... could you blame me?" he replied with a soft shrug of his shoulders.

"Heh heh heh! Don't worry, Daddy. I'll handle it..."

She smiled, mischievously so, flashing one of her fangs his way while her wings flapped softly. Leaning up before her father on the bed, Amelia grabbed her vintage nightgown by the hem, pulling it up and over her head. In doing so, she revealed the scandalous and lacy undergarments she wore; black panties and a black bra, both matching with their designs. The bra was rather normal, though it straps were thinner than usual, and the cups had the design of a flower on them. The panties however were incredibly lewd. The waistband was thin - almost like a rubber band - and the front and rear coverage were nothing more than triangles. Because of this, it wedged in between her buttcheeks like a thong, flaunting her two perfectly smooth orbs with her tail wagging above it.

A low gasp flowed from Cassandra, one that went inaudible to her sister and father. She as astonished to see Amelia wearing such clothing, and in front of their father no less! Cassandra would get cold feet from wearing her bikini, and that was a one piece! Here was Amelia, gleefully posing and flaunting her body as it was cradled in such lewd undergarments.

Maybe that's why Daddy chose her...

"Mmm... like the sight of these?" asked Amelia as she pressed her hands to the sides of her breasts, giving them a hard squeeze, "I bought these the last time I went to the mall."

"They... look nice on you, Amelia," Matt said, giving her a smile that caused her to beam.

"Heh heh! Thanks, Daddy," she responded while a rare blush formed on her face, "Okay! L-lay down! Let me try something on you! Something...new..."

Much to Cassandra's surprise, their father didn't say a word to Amelia's desires, though he remained propped up on his elbows. How often did they do this that when the redhead asked to try something new, he agreed to her request?

As for Amelia herself, she moved down until she got on her knees before him. Reaching out for his underwear's waistband soon after, the teenage bat began pulling it down his legs and thighs, releasing his cock to the bedroom around them. It was so hard, so long, so red, so thick, and its musky, sweaty scent was already beginning to fill the room around them.

Amelia just couldn't help but to give it a few whiffs...

"Sniff sniff... mmmm... did they work you hard today, Daddy?" the redhead asked, her voice holding this lustful tone as her heated eyes looked up at him.

"Haaa... no harder than usual, sweetie..." he replied with a light gasp.

"Mmm... don't worry, Daddy. I'll help you unwind..." she then gave a light hop up, her breasts bouncing, "I wasn't gifted these big tits for no reason!"

After taking precise aim, Amelia slipped his cock between her breasts and her bra, sandwiching it as she gave him a rather sultry glare. Up and down, she moved her tits along the sides of his length, stroking his prick with such lovely, warm marshmallows. Cassandra couldn't see much from where she was, but she did see Amelia's large ass pushing out towards her as she pleasured their father. Tracking their line of sight, she could see that the two were looking at each other and only each other.

It was as if the rest of the world didn't matter.

Matthew's long and throbbing cock easily penetrated through his daughter's breasts, poking out through the top of them. Green eyes looking down to the head of her father's dick, the lewd bat gave a gleeful squeal. Her father was so impressive, his cock so long, that she was capable of giving lovely little kisses to the top of his dick.

"Mmmm... mmm... mmphuaaa... so good... so fucking good," said the redhead as she tasted his salty, bitter precum on her lips.

The sight was so enthralling to Cassandra, despite being so lewd and taboo. Amelia - her older sister in a way - was titfucking and pleasuring their father's dick. It should have been disgusting but... Cassandra's plump legs began rubbing together so needfully. Her pussy was getting warm, wet too; it was throbbing, and her nipples were getting so hard, straining against her pajamas.

"Heeeyaaaaaa," Cassandra moaned, her hand sliding between her legs to rub at her pussy through her pajama bottoms.

Just as quickly however, she covered her mouth, hoping her father and sister wouldn't hear her. And somehow they didn't, for they continued on as if nothing was amiss. This allowed the raven-haired bat to keep exploring this lustiness she was gaining, as her hand slipped into her pajama bottoms. Now she began rubbing her fingers against her warm, wet cunt, discovering an itch within her that was only growing in strength. Merely stroking her womanhood just wasn't good enough; she needed more! So she began pushing a finger into her pussy, sending an electric spark that flew through her like a rocket.

"Mmmmmnnnn!" she groaned lowly, though she wanted to scream it out so much louder.

Cassandra couldn't believe herself, masturbating to such a disgusting image. And yet she couldn't help it; her lust was uncontrollable, driving her to do something so despicable.

To do something like this... oh... why did it feel so good?

"Mmmpuaaaa!" Amelia cried as she pulled herself from her father's dick again, "That's a lovely tasting cock. Oh... shit..."

The redhead's working breasts started to pick up in speed, adding more friction as she stroked up and down, up and down, up and down. A slick grin even appeared on her lips while she placed her hands to the tops of her breasts in such a cute pose. Smiling up to the wolf she pleasured, the redhead could feel his dick starting to pulsate within her chest. She knew it was coming soon, and wasn't displeased.

"Nnngh!"

Warmth splashed between Amelia's tits as her father began cumming, a moan flowing from his lips while she giggled gleefully. The cum he shot out was so voluminous, it started to slid up and fill the crevice of her mounds. Her father was an incredibly potent man, so with every shot of cum he gave, Amelia licked her lips with such sordid desire.

"Mmm... Daddy..." she moaned, her green eyes looking up towards his face.

Eventually it stopped, though by then her breasts were splattered white with cum. Snickering, the redhead moved her head down, wrapping her soft lips around the head of his dick to give it a few more suckles.

"_Sluuurrrrrppp!_Mmmmph! Mmmmm... tastes so good," Amelia said as she pulled back, where she gave a sultry wink to her father, "I bet younger men would be jealous!"

"Ugh... Amelia..." Matthew groaned as he relaxed after his orgasm, "Is that... suppose to make me feel better?"

"Well duh, Daddy," she answered whilst undoing the clips of her bra, "I wouldn't have said it if it wasn't true. Heh heh! Now then..."

Their nightly tryst wasn't over yet, but Matthew wasn't a man with an infinite libido. His cock was growing a bit flaccid now, needing some time to recharge after his orgasm. Fortunately for him - and much to Cassandra's surprise - Amelia knew just what to do in order to return her father's vigor. Just how often did this happen for the redhead to be so skilled at this?

Pursing her lips again, Amelia began to suck and clean the cum straight off of his cock, even licking down to clean his knot and even some bits of cum that stained his balls. Matthew moaned from the care and dedication, watching as she gave his length a nice spit polish.

It was practically radiating.

"Oooooh... look at it," Amelia said as she flashed her father a grin, "Heh heh... it's so big and... so young... let me just..."

Pursing her lips, the bat placed a kiss upon Matt's stomach while her hand wrapped around his cock. Slowly she began rubbing it up and down, all while kissing up and along her father's body. Each kiss brought a soft sigh from his lips, which further emboldened her movement. Further and further Amelia worked her way forward, not coming to a stop until she reached his chest. And once she did, her eyes seized upon its target.

Mouth opening up, Amelia licked and lashed at his nipple with her tongue, moaning from the taste of his heated and sweaty body. Matt moaned too, her touches causing a rush of energy to flow through his body, especially around his cock.

"Oh Amelia," he groaned as she worked herself away from his nipple, up to his mouth where, "Mmmfff..."

They kissed, eyes closed, mouths pressed to one another. Their tongues slicked and slam against another, clicking like puzzle pieces. They softly moaned, with Amelia's hand still wrapped around his cock to jerk it off. Thanks to that and her kisses, well, its by no stretch of the imagination that Matt's cock never got the chance to grow truly flaccid. If anything, it got even harder.

"Mmm...POP! There..." Amelia said as her green eyes stared down towards his dick, "Nice and big... okay!"

Standing up before her father, the redheaded bat hooked her thumbs in her panties' band, pulling it down until they slipped off of her feet. And once they did, she climbed her way upon her father's hips, straddling him.

Cassandra watched as her father's long and thick cock slapped up against Amelia's buttcrack, sandwiching between those two cheeks. She even wiggled and twerked her ass, jerking his cock with her buttocks as if to further flaunt her skills in front of her twin sister. The twin sister she didn't know was there.

...Right?

"Daddy... if you don't mind," Amelia said as she gently kneaded at his thigh, "Can we... can I... ride you, tonight?"

She said it in such a demure fashion, as if she didn't ride him _every_night. Sure, their positions would change every now and then, but for the most part, the 'cowgirl' position, appeared to be their favorite. Why? Just so they could look into each other's eyes? Ugh, it made Cassandra sick.

And her pussy throb.

Reaching around, Amelia grabbed Matthew's cock, aiming it up perfectly with her pussy. And once everything was nice and precise, she began moving herself down. Easily his lupine dick slid into her folds, parting them open so he could push in towards her core. A high-pitched moan flowed from the bat's lips as it did so, followed shortly after by a shudder that ran through her entire form. Her wings flapped, her red hair bounced, and her tits wobbled, all as her father's dick claimed every inch of her.

And once again, Cassandra took in the sight of her sister taking their father's cock into her tight cunt. She panted softly at it all, her grip on her stuffed dolphin growing tighter, while her other hand started to stroke her pussy more. She was getting so much wetter, forming a darkened stain in her pajama bottoms while her slender fingers pushed in and out of her sweltering cunt.

Oooooh! Fingering had never felt so goooood!

Matthew's cock sank deep into his daughter's womanhood, the bat's labia touching against his knot. When he looked up, he saw Amelia's green eyes gazing back down towards him, glowing in such a deep, lustful manner. She had not the face of his daughter, but of a _woman;_a woman who was lusting after him in fact.

Strange though it may sound but... as his hands moved up to rest on her chest, Matt couldn't help but to marvel at his daughter. Here where the line between father and daughter were crossed long ago, he no longer felt ashamed viewing her in a more sensual light. Her youthfulness, her athletic, tomboy figure, her green eyes, and that red hair he remembered arguing against when she first asked for... though folded into allowing her to dye it not too long after.

"Heh heh... aaaahhhnnn... s-something wrong, Daddy?" Amelia asked as she struggled to keep up her feisty attitude among her lusts.

He didn't say anything though, allowing his movements to speak for him.

Giving her breasts a pleasant and tight squeeze, Matt could feel how smooth they were in his hands. His thumbs then slid over her pink nipples, moving up and down, up and down. His touches coaxed another moan from Amelia's lips, falling deeper into her lusts as her body was steadily toyed with. Her father knew her body so well; he could probably bring her to orgasm with his touches alone, honestly. And as if to prove it, he gave her two nipples such a hard, rough pinch, causing her to screw her eyes shut and give out a loud groan. Even her wings struggled to remain still, as they fluttered about uncontrollably on her back.

"Fuuuuck! Dadddyyyy!" she groaned, "Aaaahhnnn!"

Slowly, his hands moved away from her breasts, instead sliding down the sides of her body. Resting on her perk rump, his brown eyes gazed down to where his cock met her pussy. Without a word, he slowly guided his lover down on his dick, spearing into her folds and pushing deeper inside. He didn't stop, couldn't stop, not until every inch of her amazing pussy was wrapped tightly around his length.

How did her body do it? How did her body take in their father's monster cock? Cassandra pondered that as she furiously fingered herself to the sight, stroking the sensitive walls of her cunt while her sister gave out yet another lustful moan. Their dad's dick was amazing! Big, long, thick, and oh so red! And now that Cassandra truly took the time to look at it - gaze upon it as veins stood proudly among every inch of it and sweat poured along its glands - she wondered if her body could take such a thing?

Could she? If Daddy fucked her... could she take it? Cassandra... _didn't_think so.

Matt's head pulled back in lust and love as he felt Amelia's velvety walls squeeze on his cock. No matter how many times they did this, her pussy never once lost its tightness. In fact, it felt perfect for him; like their many times of making love had only prepared her womanhood for him, and him alone. A bit conceited yes, but he couldn't help but to let that thought run through him.

Truthfully, the same could be said for Amelia. Call her egotistical or whatever, but she felt as if her father's cock was perfect for her. Like a key and a keyhole, he fitted inside of her so wonderfully, despite the differences in size. She couldn't imagine anyone else pleasing her like he pleased her.

"Are you ready?"

"Yeah Daddy, I'm ready. P-please... start moving..."

PAT! PAT! PAT! PAT!

The sound of their bodies bouncing into one another reverberated off the walls. It was the only thing Matthew could hear, the only thing Matthew cared_to hear. Well, that and the lovely sound of Amelia's voice whenever she gave a sultry moan. He felt his cock run up every inch of her cunt, feeling every finite detail of it. All the while, he gasped and groaned not only from that feeling, but of her hands clawing at his chest. Staring up into those dark, lust-filled eyes, he couldn't see his daughter anymore, but instead a most perfect _woman.

Cassandra could see it all, even from her limited view. The way her father and sister's eyes laid upon one another, taking in each other's sight. How Amelia's body, her hair, her breasts, every inch of her form, all bounced on his length. His hefty balls swaying up and down with his every thrust into her. And that knot, batting and beating at her cunt, demanding to slide inside, yet kept out until the moment was necessary.

Only they could be so _perfect_for one another, like they are now.

The maddening feeling made Matthew forget about the world as he only focused on Amelia, and not of the door. The door that was open, just ever so slightly. He didn't notice the green eyes that stared through the gap of the door, watching as the two made such pleasurable love. So it was only by pure coincidence that he decided too...

"Wait... nnghh... w-wait, Amelia," he grunted, "Amelia... s-stop..."

"Wh-what? D-Daddy? Is something wrong?" the redhead asked, to which he shook his head.

"No... I just wanted to try something..." he chuckled softly, "If... you don't mind..."

She shook her head, allowing her father to do whatever it is he pleased with her. So grasping her by her butt, Matthew began turning his daughter around slowly. It was so strange, so new to feel her pussy turn on his cock in a swirling manner. Not to say that was a bad thing, mind you, because he didn't stop turning her around, not until she was riding him in reverse, giving the wolf the perfect sight of her magnificent back.

Honestly... it made Matthew chuckle. Amelia loved to get fucked doggystyle, so this was a little bit different.

With his daughter in position and his hands on her waist, the wolf began to thrust into her. He slammed his dick up into her pussy, coaxing such fresh moans from her open mouth. Her green eyes closed shut, her head lay back, and she spread out her legs wide on her father's cock, allowing him unbridled access to her pussy.

Unbridled access... and unbridled viewing.

Cassandra gasped as she could see the face of pleasure that sat on her sister's face. She looked like a lewd slut, enjoying the greatest ride of her life. Or, no, she looked like pure euphoria, hanging in that blissful state of consciousness and ecstasy. Their father's dick was driving into Amelia's pussy with so much power, Cassandra could see what he got to see. She could see Amelia's breasts and hair, bouncing up and down, ebony nipples standing so hard and erect against her brown fur.

Cassandra focused entirely on her twin, watching as they made love and what that did to her. Her face, her screams of lust and love, it all resonated with the demure teen. So desperately she wanted to push through the door, to experience the same dizzying heights her sister was experiencing! But she remained drenched in the shadows of the nighttime hall, simply watching the scene unfold more and more while her own fingers began to speed up.

Their torrid affair eventually became too much for Cassandra to handle, and she pulled back from the door way. But she did not leave, no. Her grip around her stuffed dolphin grew tighter, and her thrusting fingers increased in speed and power. Cassandra closed her eyes as she leaned herself up against the wall, masturbating in full to the image of the two fucking. But in her mind, the image of Amelia bouncing on Matthew's cock began to shift and morph. No, no, in her head, Cassandra imagined _herself_being thrust upon that lupine dick, taking their father's love and lust for her own.

And that sent such extreme shivers down her spine!

"Mmmmmmm!!!"

Cassandra covered her mouth with her stuffed dolphin, though her fingers increased in speeds. Through the still open door, she could hear Matthew and Amelia's bodies colliding, adding more realism to her lewd thoughts. Yes, it was her bouncing on her father's cock, and those moans were not Amelia's moans, but her own.

"Amelia! Nnnghhh! Amelia!" Matthew suddenly groaned as his grip on her body grew tighter.

Moving up whilst till thrusting into her, Matthew's chest met Amelia's back, his hands sliding up her body. Grabbing upon the bat's perky tits, the wolf squeezed and gripped upon them, all while he continued pumping his cock into her amazing cunt. Something had awakened within her father then, something decidedly more... primal. Baring his fangs, he began to bite upon her shoulder, while his brown eyes screwed shut.

"Oh fuck!" Amelia cried out as she gripped upon her father's head, the sound of it alerting Cassandra.

Begrudgingly - yet ever so lustfully - the black-haired bat pulled her head back to the gap in the door, peering through it to see her family. She could see her father's limit approaching, his cock tightening hard within Amelia's cunt. Realizing what was about to happen, Cassandra began pumping her fingers furiously within her pussy, matching the speed of her father's dick as he began pounding into Amelia's cunt harder and harder. It was vicious, it was wild, it was torrid, it was taboo, and it was amazing!

With every thrust, Amelia's cunt was worked open more and more. His knot was like a battering ram, forcing its way into her dungeon walls with every successive strike. There was no stopping it, and Amelia didn't want to stop it. No, she looked forward to it. Looked forward to the moment where it it would finally go...

POP!

"Hahh fuck!" she moaned, her pitch high as her cunt clenched around his lupine cock.

Finally her father's knot slipped in, stretching Amelia's cunt well beyond what was normal for a girl her age. When Cassandra gazed down to where they were connected, she could see how wide her twin's pussy had been stretched with that bulbous sack within her. Not only that, but when Matt pulled back, it sent a surge of pleasure running through the both of them, causing the two to give out such lustful moans.

They were stuck together, knotted like true beasts in the wild. And as Cassandra watched them, all of time seemed to come to a stop. Not one person budged, not until...

"Hoooooohhh!!!"

"Haaaaahhhh!!!"

"Mmmmmmm!!!"

All of it happened at the exact same time, almost as if by fate.

Matthew began cumming, shooting his seed deep into Amelia's pussy. His load soaked her walls white with his cum, and with that knot in the way, there was no escaping. But his spunk was so great, he felt some of his cum stream down his dick, off his balls, and onto the bed and floor below. He just couldn't stop shooting his cum, almost to the point that it was overflowing!

And that drove both Amelia and Cassandra over the edge. The redhead climaxed as she felt her father shoot such thick wads of cum inside of her, a stream of her juices splattering upon the bed and floor beneath them. At the same time, Cassandra's knees buckled, clamping down around her hand as she too started cumming over her own fingers. The black-haired bat shuddered uncontrollably, her body slumping up against the wall as her soft pants echoed silently against the night air.

Pure.Bliss.

But as that state of ecstasy began to subside, reality returned. Cassandra pulled back, her hand slipping out of her pajama bottoms and into the night air. The musky scent of her arousal had coated her fingers, and they even glowed in the darkness of the hall.

Did she... really just do that? Did she really just finger herself to the sight of her father and sister fucking? That... had _never_happened before. The sight should have been disgusting! She should have called them out! And yet... and yet...

Leering through the gap in the door once again, Cassandra saw a completely different sight. Their orgasms over though his knot keeping them tied, Amelia and Matthew had shifted positions. The bat now laid on the bed chest first, her father laying atop her. But his tongue lovingly licked and lapped at her head and face, much like an affectionate dog. It was rather cute, really, especially the way Amelia giggled from the ticklish feeling.

"Hah hah hah! D-Daddy! Stop!" she cried, though he shook his head.

"No..." he replied, "Mmm... you taste so good, Amelia..."

"Dadddyyyyy!"

It was like a light switch. One moment they were fucking like man and woman, the next moment they were like father and daughter. How did they do that? How could they do that? And why... why did that make Cassandra so... so...

Jealous!

Her heart throb in a new, unique way, a sense of defeat flowing through her. For some reason, Cassandra felt so... _pathetic._Like she was somehow lesser of a person. Frowning, the black-haired bat looked again at her fingers as they laid drenched in her juices. Now feeling such extreme disgust with it and herself, she brushed her hand against the wall in an attempt to clean her fingers of her orgasm.

She just wanted to _cry_herself to sleep.

Silently, Cassandra got up from the floor as she tugged her stuffed dolphin close. Already she could feel slight tears swelling in her eyes as she quickly made her way towards her bedroom. She was trying to escape it, trying to outrun the thoughts of Amelia and their father_being_together.

It_didn't_work.

But since she left, since she pulled herself away into the safe confides of her bedroom, she didn't notice her twin shift her head. She didn't notice the way her expression shifted, and how those green eyes leered at the slightly ajar door.

Amelia said nothing.

"Do you want to go again... sweetie?"

"Of course, Daddy. Anything for you."
