Trevor's Trials - Volume Five

The Library

Thursday, November 12th

3:47 PM

"An easy way to think of it, is like you have a six-pack of soda, if you drink one, you have five left from the six-pack, so five-sixths."

"I... think I get that..." The bear cub nodded lightly as he wrote down my tip in his notes.

I continued on, "Go ahead and try the first five problems in your workbook." The bear nodded again, and started to work on his math problems.

It was Thursday afternoon, school had left out around half-an-hour ago, and I had met Alvin here for a tutoring session. On a recommendation from Mykell's mother, Alvin's parents contacted me earlier in the week, asking if I were available to help the boy out with his math work. I suppose word-of-mouth is actually paying off.

Alvin's a bear cub, in either fourth or fifth grade. He's a bright boy, but is apparently having a little trouble understanding fractions.

So here we are, sitting in one the private study rooms in the library. I'm lucky to be so accustomed to this tutoring stuff, because I've been unable to really focus on anything for the past few days. I've been far too tense, impatiently waiting for my visit to San Montana University, the school I plan on attending next semester.

The thing is... for the past few days I've been excited about that trip for a new reason. After the tour, I get to see Anton again. It feels weird to say it still, but... my boyfriend.

Since last weekend, we've talked a few times, and texted a bunch, but honestly, I could not wait to see him in-person again. Also, I was getting increasingly excited about what we might do...

On Saturday when we first met, out interactions escalated a lot further than I expected them to, and it was fairly likely that we would continue that trend, except this time, it would be just us. That is to say, no elementary school cubs with abnormally massive dicks this time.

Thanks to my experiences with Avery, Mykell, and the twins, I was now unreasonably suspicious of any cub I saw, even now sitting here next to Alvin, the thoughts kept creeping into my head, "I wonder how wide he'd stretch me...?"

The next words he spoke had me frozen with fear.

"What if it's too big?"

What the hell?!? I was sure I didn't say it out loud... First, these cubs have arm-length dongs, and now they can read minds too?!?

Inexplicably, I was able to keep my composure to a degree, "W-What...?" I responded gravely.

"The um... numberator... what if it's too big? I can't have seven sodas in a six-pack, right?"

I let out a breath of sheer relief. Alvin hadn't looked away from his work while asking the question, so thankfully, he didn't see me trembling.

"Oh... Well, first, it's 'numerator', and secondly, that's what's called an 'improper fraction', for those we'll need to turn it into a 'mixed number'.

Alvin scratched his head, feeling a bit confused at the new concepts, I figured I should ease his hesitance a bit.

"You know what, I'll go get a calculator from the librarian, that will make figuring them out a little easier for you."

"Oh yeah, that might help!" The boy seemed enthusiastic at the idea. I smiled back at him, then made my way to the front desk, I needed a break to freshen up anyway.

The library seemed unusually barren, especially for a school-day afternoon. On the way to the front desk, I didn't see anyone browsing or reading anything. I caught a glimpse of what looked like a cub carrying around a bunch of books, but they passed by pretty quick. At least that meant we didn't accidentally stay past closing time.

Upon reaching the front there was a sheep lady sitting at the desk, absorbed in some novel, I guess not even the librarians had much to do at the moment.

I stepped up to her desk, "Hi, any chance I could borrow a calculator?"

She looked up from her book, seemingly a bit surprised that there was even anyone in the building. "Oh! Hi sweetie! Sorry, I guess I was kinda zoned out there. What did you need?"

"Er, it's no problem, just need a calculator." I restated to the woman.

"Oh!" She looked around for second on her desk before turning back to me, "Unfortunately, you're out of luck... You see, we keep the calculators, and a few other school-related tools locked in the supply drawers..."

She paused for a moment, seemingly to judge my reaction before continuing.

"And... the morning shift librarian, accidentally took the keys home..."

"Oh... Um..." I responded, a little stumped at the situation.

The woman looked down to what I assume was some kind of work schedule, "The head librarian has her own set of keys, and she'll be here in around two hours, but for the moment, I can't help you." She looked back towards me, "Anything else?"

"No-- Oh! The um, bathroom key... Err..." I caught myself a second too late, "Right, No keys..."

She opened her hands apologetically, "Sorry."

"It's um, no big deal, I guess..." I walked away from the desk as she picked her novel back up. Shrugging, I grabbed my phone from my pocket, and opened up the calculator app.

Upon getting back to the study room, I turned off the lock on my phone, and set it down onto the desk for Alvin to use the calculator function, and we continued working on his math skills.

"Alright... so that means... 26/8 turns into... um... 3 and ¼?" Alvin looked to me hopefully.

I smiled inwardly, partially at my own tutoring skills, "Yep! You got it!"

A smile grew across the bear cub's face as he quickly wrote the answer down on his worksheet.

I glimpsed up at the clock, "4:27, we should finish up, your dad should be here to pick you up any minute now."

"Oh! Yeah!" The bear cub, jumped to attention, and started gathering his stuff, "I gotta hurry, it's spaghetti night!" Tossing everything into his backpack, he took off out the door.

*POW*

"OOF!"

"ACK!"

Trevor looked over to the door to see Alvin climbing back to his feet amongst an assortment of spilled books. "Alvin? You alright?"

The bear cub stood back up, still in a hurry, "Yeah, I'm fine, see ya later Trevor! Sorry, Avery!" With that Alvin, made his way towards the exit.

"Avery?" I turned to see the fox cub on the ground.

"Ugh... Oh, hey Trevor..." The boy had apparently been knocked over when Alvin bolted out the door. Also, he had apparently been carrying a generous selection of books.

The fox boy started collecting his dropped texts, I knelt down to help him, "You okay, Avery?"

"Yeah, I'm good." He seemed a little off, usually Avery is fairly cheerful and upbeat, but today he came off as a bit despondent.

Before I could inquire about his mood, the books that I was picking up caught my eye. "Basic Algebra", "History of Poetry", "Discovering Biology"...

"Avery, what exactly are you reading...?"

"Huh?" The boy looked over at the books I was holding, "Oh, those are just for school."

I was taken aback at his answer, "These are for your classes? Most adults I know can't handle some of this stuff..."

I knew that Avery was in some advanced placement classes, but this stuff was far beyond what I expected he was learning.

"It's really not that much..." Avery stood back up, "It's just I have a lot of stuff due over the weekend, and a test tomorrow... It's not a big deal, just a few more books than usual."

The boy was definitely a tad on the melancholy side today, and as usual, I'm just a pushover, when it comes to sympathetic situations, "Ave, did you, er-- want a little help? I am a master tutor, you know." I smiled at the boy reassuringly.

"Oh, ummm... I don't know... Can you help me with recognizing types of poetry?" The boy asked.

My mouth curled into a small smirk as I responded:

"Silly young fox boy"

"My tutoring skills, unmatched"

"I will prove my worth"

Avery looked at me quizzically, "Why are you talking like that?"

I stepped back into the study room, "We should get started, if you can't even recognize a haiku."

"Oh... That's right!" Avery followed me into the room, and set down his books.

To my surprise, the boy's knowledge of the subjects was genuine. I helped him study, using exercises and passages from the books, and he was able to keep pace.

"Umm... 14 lines is... a sonnet..?" Avery looked to me expectantly.

I nodded to the boy, "Good job! I don't know what you were worried about, Avery. You know this stuff inside-out."

"Yeah, I guess..." Avery still wasn't his normal lively self. Possibilities kept running through my head as to what could be the problem.

*THUMP*

Distracted a bit by my concern, I had apparently knocked one of the books off of the desk.

"Whoops..." I knelt down to grab the textbook that had apparently slipped between the desk and the wall.

*BZZZ* PERSONA! *BZZZ*

I heard the familiar sound of my text message alert going off as I was in the midst of reaching for the book.

"Oh! Whoa!" Avery yelped out in surprise.

Upon Avery's exclamation, I forgot about my interest in the fallen book. "Something wrong?"

"You um... Got a text message from Mykell's brother." Avery still had a bit of shock in his voice.

I considered that for a moment, wondering how he was able to access my phone to see who the message was from, before realizing that my phone must have still been unlocked from my session with Alvin.

I quickly stood up, glancing at the phone sitting on the desk to see the text that Anton had just sent, an image... a very provocative image.

Displayed on the phone was an image of Anton in a very suggestive position, wearing absolutely nothing, with a strategically placed washcloth located just below his waist.

My jaw dropped as I stared at the image for what must have been a good 15 seconds before noticing that Avery was also captivated by the photo.

I grabbed the phone and turned off the screen. I was well aware that Avery and the other cubs saw each other, and myself for that matter, in compromising positions fairly often, so I wasn't particularly concerned with him being able to comprehend the concept, but if nothing else, he just didn't need the distraction.

"Err..." I started to try and justify the text message, "Anton's kind of excited to see me in a couple days..."

"Yeah, I guess he is..." The cub fidgeted a bit in his chair and turned back down into his book, still obviously bothered, and now seemingly even a bit physically uncomfortable.

I grimaced a bit at the boy's discontent, "Avery, come on... What's up...?

Avery looked back to me, "Huh? What do you mean?"

"I've known you since you could barely walk. I know when something's wrong."

My statement seemed to catch Avery off-guard, he stared at me surprised before looking away and scratching the back of his head.

I leaned in a bit, "Look, you obviously know all this material, that's not what's bothering you. So, come on Avery..."

"It's really... nothing..." Avery still apparently unwilling to confide in me, he looked back to me to gauge my reaction, seeing only a stern demeanor that I rarely displayed.

"I'm just a little... backed up..." Avery finally answered, openly embarrassed at the admission.

"Backed up?" The expression on my face now showing more confusion than anything else.

"Yeah... You know..." With that, he squirmed a bit in his seat, as he reached down to adjust himself.

"Oh!" It took me a moment, but I realized what he meant.

"I haven't really gotten off since before Halloween..."

Avery's confession was unanticipated. Thinking back, I recalled the last time that we had done anything together.

"The night of the sleepover, you mean? That was nearly two weeks ago."

The sex-drive of a 10-year old cub is generally non-existent, so two weeks of celibacy for one normally shouldn't be a dilemma of any degree. However, Avery and the others were clearly not average cubs, and the past 13 days had clearly taken a toll on the fox cub in front of me.

"Yeah..." The boy continued on, "I mean, I've had a lot of school work and stuff to do, so I'd been putting it off, and I've been fine up until today."

"Just today?" I questioned.

"Well, Mykell's brother is apparently going to be here on Sunday, so all day he's been going on about topping him, and the twins still have Halloween candy and they're always 'sharing' it, and now with that image on your phone..." Avery trailed off after that, further fidgeting as he adjusted himself again.

"I see... Well, I could help you out..." I suggested to Avery expecting him to jump at the chance.

"I don't think we can..." an unexpected response from the boy, "My parents are at home, there's no place we could go."

I considered it for a moment, and Avery had a point, with his parents home it wouldn't be a good idea to go to his house. In addition, my parents were also at home, so driving back to my house wasn't an option either. Not even the bathroom was an option, with the library keys missing, although upon remembering that, a new possibility came to light.

I thought for a moment to consider the details, as I noticed that there was a lock on door of the study room that we were in. "What about in here?" I suggested.

"Huh?" Avery had a lack of confidence in the idea. "What do you mean, we can't do it here, anyone could just walk in."

"No they can't, we can lock the door. I talked to the librarian earlier, they don't have the keys right now." I pointed out to the boy.

"Oh..." I could practically see the gears turning in Avery's head as he considered the new information. "We- we still can't..."

I was admittedly taken aback by the boy's continuing rejection, The couple times we had consorted in the past, he was more than eager. "Why not? No one can get in, not that there's anyone else in this place anyway."

"Because..." He looked down to the floor, "I'd make too much of a mess..."

Again, the boy had a point. The amount of fluid that Avery could produce was staggering, I of course had witnessed it, first-hand. It would be impossible to clean it up, especially considering the carpeted floors.

"Well, you wouldn't make much of a mess, if... you knotted me, again." I offered yet another solution to the boy's qualms.

Avery's ears perked up, but only for a moment as he further rejected the suggestion. "No... I couldn't... I'd uh... fill you up too much..."

I shrugged, "Avery, you 'filled' me pretty good last time." I placed my hand on my belly, "It felt a little weird, but I can handle it."

Avery shook his head, "It wouldn't be like last time." He paused for a moment before continuing, "Last time, I wasn't backed up... It'd be a lot more now..."

My eyes widened at that last bit, "More?!"

The boy nodded sullenly.

I contemplated the issue for a moment. Last time Avery had cum inside me, the amount he expelled left me visibly swollen with the substance, and he was telling me that this time it would be an even greater amount?

I looked back at the gloomy boy, I simply couldn't stand seeming him so depressed. "Let's do it anyway."

Avery's big fox cub ears perked up again. "Wha- Really!?"

I nodded, the combination of empathy I felt for the cub, and arousal I felt from Anton's text was too much for me to suppress.

I stepped over to the door, glanced around outside to see if anyone was around, and then closed the door, locking it.

I turned back to Avery, "You err... should get yourself ready."

He didn't need any more encouragement, Avery popped up out of the chair, immediately pulling off his shirt.

I grabbed all of the books off of the desk, stacking them on the floor. Turning back to see Avery, completely naked, and it was clear why he was so uncomfortable a minute ago. The massive organ that I had grown so familiar with was already halfway exposed, and looked to be diamond hard.

"Wow... No wonder you were so upset" I said to the boy as I started disrobing.

"Avery's mood was clearly improving, but he still looked a bit unsure, "Are you really sure?"

I smiled to the boy as I walked over to him, "Sit down." I motioned the boy into the chair, "I need to get you really wet."

I leaned in, once again face-to-face with the impossibly large shaft that belonged to this 10-year-old, but unlike last time, I had no reluctance.

I opened my mouth wide, accepting the tip in as far as I could, until it poked the back of my throat, I began lightly sucking on the object, and running my tongue all over the sides of it.

"Oh man... Trevs, you're better at this than last time."

I smiled to myself as I heard the boy use his usual nickname for me, his mood was bettering.

The boy's length continued expanding, growing past 9, 10, 11 inches. Avery's hands moved to the back of my head, and though he was struggling to resist, I could feel him thrusting his hips slightly.

I repositioned myself, giving him better access to my throat, and attempted to take him deeper. Thinking back to my activities with the twins on Halloween, I was able to consume the entirety of Barry's 11-incher. Avery was a tad bigger, but I felt that I had to at least try to match that performance. Unfortunately, I had not taken Avery's superior girth into account.

I forced myself downward, the tip finding its way past the entrance to my throat as I continued tongue-bathing the circumference of the shaft. Avery seemed to pick up on my intentions, and tried to provide assistance, attempting to angle his small thrusts better into my throat.

I began to feel my jaw straining, unable to stretch any further, and even with Avery producing sizeable gushes of precum, lubricating my throat, the thickness of Avery's dick was just too much to handle.

"Oof... Y-You got most of it in Trevs, I don't think the twins can even take me that far!"

Satisfied with Avery's praise, I decided that I had gone as far as I could go, and eased back, letting the tip rest in my mouth as I ran my tongue over the rest.

At this point, Avery was fully exposed. At close to 13 inches, it was easily the biggest cock I could ever imagine seeing. Pulling the tip out of my maw, I couldn't help but to revel in awe at the magnificence of it for a moment, before moving to run my tongue along the base.

After the first few tongue lashes at the base, the boy's knot started to form, slowly expanding outward, easily the size of a baseball, and still growing.

"Trevs, we need to get started... I'm gonna start leaking all over..."

Avery was right, upon removing the tip from the inside of my maw, the boy's steady stream of pre was now spilling like a running faucet. I ran my tongue around the tip a few last times, savoring the taste of Avery's essence before complying.

"Yeah, um... Like this."

I pulled myself up onto the desk, lying flat on my back. Avery caught on quick, and positioned himself swiftly, moving between my thighs, resting my legs on his shoulders.

He looked at me, appearing almost scared to hear my response as he spoke, "L-Last chance Trevs... This is probably gonna end up being kinda uncomfortable for you..."

I could feel the boy's hand trembling against my thigh as he awaited my permission.

I smiled and nodded to the boy, "It'll be fine."

That was all he needed to hear, not a single second had gone by before I felt that searing warm tip against my tender ring.

I took a deep breath and held it in as I started to stretch around Avery. That monstrous size is something I was sure I would never get used to, he was only a couple inches in, and already I felt as if I was at my limit.

"Haah... Oh man... Trevs, I don't think I'm gonna last long... If I'm gonna tie you, I'll need to pick up the pace."

The boy's words had an inquiring inflection to them, but it was more of a warning statement. Before I had even acknowledged, he was starting to press in stronger, urging himself deeper at an increased rate.

"Unnnf..." I grunted as I answered, "Yeah... It's fine Avery."

He pounded into me roughly, stuffing more and more of the massive cock into me, displaying a strength that an 10-year old shouldn't be able to achieve.

"Holy s-shit, Trevs... You're super tight..." Avery held still for a moment, undoubtedly struggling to hold back his orgasm. A moment later he let out a breath, and his hips started moving again.

I reached forward, my hands finding the the silkiness of Avery's behind, and held him tight, trying to get him deeper inside me, to the point where I could feel his heartbeat resonate through his incredible length. Each pulse spurting another shot of precum into me, slicking my insides, helping him reach my deepest depths.

"Ahh..." I moaned out, a bit louder than I intended as I felt his knot strike my behind. His entire shaft, up until that softball-sized swell, was now inside me. I glanced downward, seeing the expected bulge in my gut caused by the boy's firm spire protrude outward, and then contract just as quickly.

*SLAP* *SLAP* *SLAP* *SLAP* *SLAP*

With Avery's length as deep as it was, his equally impressive balls were now close enough to strike my ass with each thrust, the new sensation adding another element of bliss to the already intense pleasure.

The boy's motions started becoming inconsistent, I could tell he was getting very close, and he had not yet fit his knot into me.

"Unngh..." I struggled to get the words out through the overwhelming euphoria I was feeling from Avery's utter annihilation of my pleasure center. "Avery... You need to go HARDER!"

Avery bit his lip and nodded, forcing himself into a steady pace again, further increasing the strength of his thrusts.

*SLAP* *SLAP* *SLAP* *SLAP* *SLAP*

I clenched my fists, grit my teeth, and threw my head back against the desk as I felt the mass powering its way into me, ripping me in half.

"AHHHH! F-FUCK, TREVS!"

*POP*

Not a moment after the bulbous knot popped into my passage, I felt the blazing hot cream start bursting inside me, gushing as if it were coming from a hose.

The warmth spreading inside me was all it took to bring me to orgasm, I squirted my bit of sperm onto my own chest, the thin stream of fluid reaching up almost to my neck

"Oh, man..." Avery held tight against my body as he continued filling me. Two, three, four, five huge blasts of cum coating my insides, and the fox cub was showing no signs of slowing down.

Over 90 seconds had passed, and the boy's orgasm had not tapered at all, if anything, the bursts were getting even more robust. Avery's hips were still moving, slightly tugging at the knot that was locking us together.

My body was still limp, my head laid back against the desk. I started feeling bloated, my midsection growing heavy. I tilted my head forward to see, and my eyes went wide.

My gut was swollen well past its normal size, it looked like I had swallowed a basketball, a further-inflating basketball at that.

More and more of the boy's semen poured into me as the orgasm's duration passed two full minutes. Avery was definitely not kidding about there being "a lot more".

Avery's hips started to slow and eventually halted, and the seemingly unlimited cumshots finally started to taper.

I stared up at the ceiling, breathing heavily as I tried to get used to the pressure in my torso. It didn't help when a certain cub collapsed onto me.

"Oh Trevs, you are the best! Thank you sooo much!" Avery held me tightly, squeezing me in a hug.

I placed my hand on the cub's head, "Uhh... No problem Ave, but not so tight, please."

"Oops!" Avery eased off of me, looking down at his handiwork. "Oh man... I stuffed Terry pretty full once, but nothing like this." I couldn't help but smirk, as the boy seemed impressed by his own output, placing his hand against the watermelon-sized swell.

"I um... hope it's not too uncomfortable?" The boy's expression turned to concern as he awaited my response.

I made sure to keep the smile on my face as I answered.

"Fox cub filled me well"

"Stuffed me far past my limit"

"Best I've ever felt"

Avery's face turned back to joy, "Haiku! I noticed this time!" He fell back on me, hugging even tighter than before.

"Oof! Avery, too tight!"

It took about 10 more minutes for the knot to shrink enough, and Avery was able to pull it out. It took considerable concentration to keep Avery's fluids from spilling out as he removed himself from me, but we somehow made it through the entire ordeal with minimal mess made.

I got to my feet, and the first thing I noticed was how heavy I felt, I had to have gallons of Avery's sperm in me. As unreasonable as that sounded, I had long since given up on trying to understand how a lot of things about Avery were possible.

We got dressed, gathered the books, and got ready to leave. Luckily, the library was still empty as we made our way out, although I did get a puzzled glance from the librarian as I passed by. I could almost hear the thoughts running through her head, "Wasn't he a little slimmer earlier?"

We made our way out, and as dusk was approaching, I gave Avery a ride home. The boy was strangely energetic for someone who just shot their weight in sperm.

"Thanks again Trevs! You are the best ever! I still can't believe you helped me like that!" The boy was still showing his appreciation as he exited the car.

"It's really no problem Ave. Just... promise me that you won't... neglect yourself for two weeks anymore?" I shot the cub a sharp glare.

Avery looked down, still a bit embarrassed by the whole situation, "Yeah... It won't happen again." He closed the door, and headed up the walkway to his house, waving farewell as he went in.

I began the drive back to my house. Placing a hand on my swollen gut I started trying to come up with a solution to the last remaining problem. How was I going to get past my parents looking like this?
