Heeeey. Took a little longer than I meant to before getting back into these. Whoops... x..x But oh well! I have about 2 weeks before I go out of town for Thanksgiving. Hopefully I can complete the last 10 prompts before then; SHOULD be fairly within my abilities, so that's good.

To the story! This one took... tbh a way longer time to figure out than I wanted it to. Finally just decided on some semi-random characters of mine to work with: Pueres from Day 15 (who I have not really decided on a canon job for, but in this he's a teacher because role reversal fun) and Murray from Day 4. I almost went with Taurun, but then I thought the lion/mouse combo would be fun. Hopefully folks enjoy it!


  1. Distention & Cockbulge / Scissoring / Role Reversal

(CW: Age difference, Size difference, Teacher/student)

Pueres finished lining up the stack of completed tests in his paws. The diminutive lion had to stand on a short step ladder in order to reach up to the top of his normal-sized desk. His sleekly-managed mane of reddish fur framed his small, square face, the feline teacher glad that the day was done. His usually composed formal attire was edging into the messy side, button-up shirt no longer tucked into his pants, which were more wrinkled then they'd been that morning; even his tie was askew, loosened to hang from his neck.

Now, he just had to finish gathering up the various completed works from his students of the day, and then he could head home to his lovely boyfriend. A nice, quiet night in, even with the promise of having to grade things before he was done with the day, sounded absolutely wonderful.

`Knock, knock.'

``Uh, Mister Theras?''

The feline teacher looked over to the door to his classroom, ears perking up in surprise. Oh,'' he said, recognizing the young adult stepping in. He was a senior, a short, slightly chubby white-furred mouse, small compared to some of the other students but still towering over the 3-foot-tall lion.Mister Flick, what can I do for you?''

Despite his taller stature, the rodent was the one who seemed more nervous. He bashfully brought a paw up to his opposite arm, blushing slightly as his glasses slipped slightly down his nose. ``Um... I wanted to ask you about something, sir.''

``What would that be?'' Pueres asked professionally, setting the papers into his bag, situated on his chair nearby, and facing the young man, still standing on his step ladder. It didn't help much height-wise, but it was better than nothing; even with it, though, he only barely came up to the 18-year-old mouse's chest.

Murray Flick, the student standing in his room, was very, very far from a struggling student. Not quite straight-A, but always getting passing grades and doing good work. The nerdy rodent was an exemplary student, all around, not one that would usually need an extension on a deadline or anything.

Which made it a bit odd that he was there. It seemed unlikely that the mouse was there for tutoring.

Murray let out another anxious grumble to himself, still looking away from the short feline and blushing slightly. He tried to stammer out a reply, but seemed too flustered to get it out.

Pueres couldn't help but let out a chuckle; sure, he tended to make up for his small size by being as stern and loud as he could manage with his students, but he didn't think it was enough for this kind of reaction from the young man. Just relax, Murray,'' the lion told him, the mouse finally looking at him in the face.What can I do for you?''

The rodent gulped. Visibly steeled himself, and stepped closer.

Suddenly, the young man's hands were under Pueres's arms, and he was being lifted up into the air. He yelped in surprise, not expecting to be so easily lifted by the pudgy-bodied, nerdy mouse, soon finding himself turned and set on his rump on the top of his cleared-off desk, grunting. Murray stepped in close to him, hands on either side of the older man's hips, looming slightly over him as their bodies pressed together. The lion let out another surprised yelp, this time from the fact that he could now feel a giant, fully-erect bulge throb against his abdomen from inside the mouse's pants.

M- M- Mister Flick! I-

The mouse, still blushing, leaned in and cut him off with a rough kiss. Their lips locked together, Pueres trembling as his student's paws gripped at his hip, the other up on the back of his head as he kissed him.

And kissed him WELL. The nerdy rodent was surprisingly expert at kissing, teeth gently nibbling at the older man's lip, lips dominating his own, tongue pressing into the feline's maw and tasting every inch of him. Those small paws were unexpectedly composed as they kneaded at his hip, the other's fingers curling into his red mane.

The kiss parted, leaving Pueres a panting, trembling mess. His paws had somehow found themselves up on the mouse's chest, heavy breaths huffing out of him sporadically. ``F- Fuck... I... M- Murray...''

The mouse gulped, licking his lips. S- Sorry, sir... B- B- But, I've sort of... had a huge crush on you since sophomore year. And, I didn't wanna graduate without doing anything about it, so...'' the rodent got out, still blushing hotly.And, um... my boyfriend kind of... egged me on, and said this was a good way to do it, but he's not really... um, I mean, he's better with... this kind of thing. ... I hope he was right.''

Blinking in surprise, the lion gulped. He'd... never thought of himself as the type of teacher students might have a crush on. He certainly wasn't like the muscular wolf in the gym, or the big-breasted she-bear that taught Math, or the handsome, eloquent stallion in the history department.

``You...'' the lion stammered out, now also blushing. His hands were still on the younger man's chest, able to feel his hammering heart rattling away in his ribcage; and with how close they were, the feline's lower legs had to hook around the rodent's thighs, spread apart to grind his own growing bulge against Murray's. He could feel the mouse's obviously giant cock throb against him again, even between two or three layers of clothing.

... Fuck.

Pueres gulped, and said, You... already ensured this was okay with your partner?'' The blushing, nerdy mouse nodded quickly.... I need to make a call.''

The mouse blinked, and nodded. Pueres extracted his phone from his pants' pocket, and speed-dialed his boyfriend. The phone rang for a few moments; the lion winced as he realized the hyena that he had been dating for a few years would still be at work, albeit close to getting off.

The line was picked up. ``PT? What's up, babe?'' the hyena's voice came from the other end.

Pueres gulped again, but with one paw on the young mouse's chest, he said, ``Uh, hey, baby! Um, so, something... kind of interesting just happened.''

``Oh? What's that, hun?''

``... A student made out with me, and sort of wants to have sex.''

``... Uh...?''

``Ah, he's 18! I'm not, uh, y'know... THAT.''

Oh! Well, that changes things, haha,'' the hyena chuckled casually, audibly relieved.Guess you're calling to clear a hookup, right?''

``Ah, yeah, well... that's the rule, right? Hook up with who we want, as long as we clear it with each other?'' the lion recited, blushing as he glanced up at the also-blushing mouse, still nestled between his legs and grinding up against him. Pueres, of course, hadn't used said rule yet, and even his boyfriend had only gone outside their relationship two or three times over a few years since they'd opened it.

It sure is,'' the male on the other end of the phone call agreed.Well, hey, if you wanna be THAT kind of teacher who gets with legal-age students, go ahead, baby! Have a lot of fun, and tell me EVERYTHING when you get home!''

Heh, thanks, honey,'' the lion answered, smiling. He even, dorkily, gave the anxious mouse a thumbs up.Might even take a few pictures for you, if he's okay with it. But, seeya when we get home!''

``Alright, baby, love you!''

Love you too,'' Pueres answered, still smiling as he hung up the call and set his cell phone aside, looking up at the mouse.Uh, so, yeah... Just wanted to make sure this was okay with MY boyfriend, too, hehe...''

I didn't even know you were gay,'' the mouse commented, blushing as he settled in closer against the lion.Or had a boyfriend...''

The teacher gulped, hooking his ankles against the back of Murray's thighs and gripping at his shirt with both paws. ``T- Talk later... Fuck, I really, really need to feel whatever this is in your pants in my ass...''

Murray nodded, and leaned in for another deep kiss. It was much less one-sided this time, Pueres lovingly making out with the young man now that he wasn't afraid of cheating on his partner. Despite his renewed participation, however, he still found himself being dominated by the tubby mouse, a whimper leaving him as the rodent's teeth nipped at his bottom lip.

F- Fuck...'' the feline whined, even as Murray's paws here slipping down his sides, yanking at the waistband of his pants.Oh, fuck...'' Pueres whimpered, before being drawn into another kiss, groaning into his student's lips as his belt came undone.

Their pants came off in a haze. The student and teacher kept making out, and groping at each other, and soon the lion's pants and boxers had been pulled off his legs completely and thrown onto his chair nearby, while the mouse's zipper came down, cock exposed when the young man's briefs were shoved down under his balls.

Giant balls. Huge cock. Pueres shuddered; compared to his small, fuzzy nuts and 5-inch, pink-fleshed prick, the mouse's 11-inch, tapered dick and fat, white furry balls was gigantic. He whimpered as the nerdy rodent humped and grinded on him, smearing precum onto his button-up shirt.

Holy fucking god...'' the lion whimpered, setting a paw on the mouse's cock, feeling it throb under his palm. He gulped, then said,There's- There's lube in my desk drawer, right there... Definitely gonna need it.''

Murray nodded, giving his teacher one last kiss before pulling open the drawer, still nestled between the older man's legs as he sifted a few things around and extracted the small bottle of lube. The mouse chuckled as he looked at the half-empty bottle, teasingly asking, ``Heh, have a habit of jerking off on the lunch break?''

N- No!'' the lion objected, blushing hotly and gritting his teeth; why did everyone who turned him on have to also grind his gears?I just- I mean, sometimes, after classes let out, my boyfriend picks me up from work, and he's... well...''

Hehe, say no more,'' the mouse assured, popping the cap and grinding forward on the lion, loving the feeling of his teacher's body against his dick.Mmf... I can't wait to get this inside you, sir...''

``Fuck...''

Pueres met his student for one last kiss, shuddering and trembling in the younger man's arms before he felt one of those pink-fleshed paws set on his chest and shove him back. He grunted in surprise as he thumped back into his desk, hands tucking up against his chest and legs spread on either side of the mouse's hips. His own prick throbbed in the open air, before being hidden from sight as the rodent's fat dick was set on top of him.

``Holy fuck...'' the lion shuddered, setting his paws on the giant cock, licking his lips excitedly. It extended almost up to his ribs, for gods sake! Murray was surprisingly sturdy and dominant, still blushing a bit but not hesitating to grip the lion's ankle and lift his leg up, Pueres grunting as he was bent slightly at the hip.

The mouse had a focused, hungry look in his eyes as he dumped the bottle of lube right onto his teacher's taint, letting the cold, gooey fluid spurt and ooze all over him. In moments, his balls, groin, taint, and ass were dripping with lube. Even his thick, red pubic fur was matted down heavily by the gooey lubricant.

The lion whined as the bottle was set aside and the now-freed hand pressed between his ass cheeks. His tail thrashed, smacking weakly against the rodent's legs as two fingers immediately pressed into his tailhole, the near-40-year-old man groaning in pleasure as he was spread open by a man half his age. ``Oooh...'' the lion moaned as he was fingered by the younger man, working his anal walls open and coating them with lube. He grunted, and huffed, clenching on the intruding digits, before whining as a third was added to the inside of his ass, leg trembling in the mouse's sturdy grip.

``You're gonna need at least three fingers to take me,'' the rodent informed simply, watching his teacher's cock throb, taking a moment to enjoy the feeling of the man's ass clenching around his curling, thrusting digits. He spread his fingers slightly, pressing into that warm depth, grinding them in knuckles-deep before curling them upwards. The lion cried out in surprise, arching his hips as a powerful spurt of precum jetted up his front, spattering against his agape jaw and adding to the messiness on his shirt.

``Fuck! Oh, fuck,'' the lion whined, trembling on his desk as he was fingered open. The mouse kept going for a few more moments, eliciting two or three more strong spurts of precum before, at long last, popping his fingers out of that slightly-gaped, glistening tailhole.

The mouse licked his lips, deciding, ``I think that's enough.'' He smeared his own cock with the leftover lube on his paw, rolling his hips back and, still holding the lion's trembling leg up in the air, aimed his tip for the feline's asshole. Pueres whimpered, blushing and gazing down at the young man between his legs, preparing to penetrate him. He couldn't muster a single word as Murray pressed forward, throbbing, pink dick meeting his anal ring and pushing inside almost easily.

It quickly grew more difficult.

Pueres groaned, head tilting back and eyes closing as he enjoyed the sensation of being so filled and spread open. His leg shuddered in the young man's grasp, tail curling and cock throbbing as the mouse's dick worked inch after inch into him. Thanks to the stretching and lube, it never hurt, but god did it strain his anus greatly, leaving him a panting, mewling mess as he was worked open.

The mouse had gotten about halfway in when he let out an impressed whistle. ``Holy shit, thought that was just something that happened in porn,'' the 18-year-old commented.

The lion cracked open his eyes, and gazed down, whimpering out, Wh- What...?'' Then, he saw it. A bulge in his belly, a protrusion that stretched his gut as his insides were filled up and shifted by giant rodent cock.Holy fuck...''

Hehe, right?'' the mouse chuckled, licking his lips. He rolled his hips back and thrust forward, Pueres yelping in surprise and pleasure as a few more inches were slammed into him, a matching bulge stretching his furry stomach.God, this is hot...'' Murray groaned, feeling the tight, hot lion hole clenching and flexing around his shaft, milking rodent precum into the older man's ass.

Murray began to thrust in earnest then, even without having gotten balls deep yet. His paws gripped at his teacher, one still on his ankle, the other down on his hip as he railed the older man, shoving his shirt up over the pudgy older man's stomach and nipples. Heavy, furry balls swung back and forth in time with his powerful thrusts, the nerdy rodent panting and groaning in pleasure. Precum and lube dripped down his shaft, a trickle of fluids working down his nuts and dripping off onto the floor between his feet. Pueres could only moan, mewl, and squirm, paws desperately trying to find purchase on the flat desk before finally grasping at anything, one gripping at his precum-spattered button-up shirt, the other lacing fingers with the mouse's paw on his hip.

The flexing lion prick went untouched, oversensitive and throbbing as his prostate and anal walls were bombarded by the young man's thrusting cock. Murray panted and grunted, lowering his head and gritting his teeth as he thrust in and out of the heavenly, slick tailhole, loving the way the older man clenched around him when his girthy prick grinded up into middle-aged lion prostate.

And, of course, Pueres's abdomen continued to bulge. The swelling of the rodent's intruding prick went further and further up his belly, pudgy, furry flesh stretched up slightly with every thrust into him. The lion was certain he could feel it all the way inside him, rearranging his guts and stretching him far deeper then he'd ever been before. His lower body was lifted a bit higher, shoulders still on the desk, and with a new angle to the thrusts, the abdominal bulge grew even more pronounced and pleasurably straining, his legs flexing and toes curling with every powerful thrust.

``G- God!'' the lion yelped, claws digging into his bunched-up shirt with pleasure. So full, so good, so amazingly firm and powerful with each thrust...

Fuck!'' the mouse grunted, slamming in again. His fat, furry balls smacked into the lion's lube-dripping ass, fully sheathed inside his teacher's ass. He throbbed inside the older man, feeling Pueres's insides flex and grip around him.Mmf, fuck, not gonna last long... What about you, sir?''

Fuck, oh god, oh fuck...'' the lion answered mindlessly, panting heavily and squirming as he was railed deeper then he'd ever been.I should... oh fuck, I need to keep you around, mmf...''

Hehe,'' the nerdy mouse blushed, before licking his lips.I'll take that as a compliment, sir...''

He returned to thrusting. Both student and teacher grunted and moaned, squirming and writhing together as the younger man humped hard and fast, wet balls now slapping repeatedly into the older man's plump, furry ass. He leaned over the lion, panting and huffing desperately as he was caressed closer and closer to orgasm by slick, tight older man ass.

Pueres's orgasm came unexpectedly. One moment, he was groaning and writhing on the mouse's cock, and then, he arched his hips and yelped. Ropes of hot lion jizz spurted out from his twitching tip, wildly painting his front with his own seed. He clenched around the cock in his body, flexing almost rhythmically around the younger man's dick and eliciting a sharp gasp from the rodent.

F- Fuck!'' Murray yelped, shuddering as he paused his thrusts balls-deep in the lion, gazing down at him. Cum painted across his bulging belly and bunched-up shirt, dick already receding into his sheathe even as it continued to ooze semen in water puddles onto his pubic fur. His face was red with blush, panting heavily and exhaustedly.Ah, s- sir, I...''

``Keep going...''

The mouse hesitated, and then murred lowly and nodded. He opted to pull out a moment, flipping the small lion over onto his messy front and pinning him there, one hand on his hip and the other up on his shoulder as he thrust into that gaping hole easily. The lion could only groan in reply as the chubby mouse settled his weight on top of the older man, working himself balls deep easily. Then, he began thrusting again, one knee propped up on the desk as he pounded the teacher into the man's desk.

Murray panted and whimpered, unable to last much longer. He clamped his teeth down on the lion's scruffy neck, eliciting a groan of pleasure from the older man as his balls smacked against that soft, furry rump, pounding away vigorously as Pueres found his paws grasping at the edge of the desk for purchase.

Either an hour or a second later, the mouse slammed in one last time with a firm grunt, body tensing and fingers curling into his teacher's furry flesh. Pueres could FEEL the younger man cumming inside him, a veritable flood of hot, thick rodent jizz flooding his bowels and stomach, gushing inside him and filling him with an intense, pleasing heat. He whined, blushing as his jaw parted and the involuntary noise of pleasure left him, even as he realized his own cock was pinned under his swelling stomach against the hard desk.

``Ooh, fuck, sir...'' Murray whined, burying his snout in the lion's fluffy mane. He whimpered happily, giving a few light thrusts to push his seed even deeper, painting the older man's insides with his cum.

``Fuck, kid...'' Pueres sagged, panting heavily and digging his claws into the desk's wood. He shuddered, biting his lip.

``I'll... come back later.''

They both looked to the door, which sat open. A graying, older donkey in a janitorial uniform stood in the doorway, face red and pants visibly tented. He stepped back and shut the door with a thump, visibly scurrying away.

``... I fucking forgot to lock the door,'' Murray scolded himself with a huff, slapping a paw into his forehead.

Pueres let out a dazed laugh, unable to believe anything that had just happened actually HAD. Still, he shook his head, reaching a paw back to pat on the mouse's side. It's fine, Flick,'' he told the younger man, licking his lips. Then, he wiggled his rump back against the rodent's hips, huffing softly and saying,Hey, would you mind taking a video of you pulling out of my ass? Doloro, my boyfriend, he loves watching that kind of thing, heh.''

``Oh, no problem!''

The mouse snatched up his teacher's phone, leaning back but keeping his cock buried balls-deep in the lion's ass, feeling him shudder as the rodent's heat and weight left his back. He opened the camera, filming a few moments as he rolled his hips back slowly, slowly extracting every inch of his softening mouse dick from the older man's gaped anus. It popped free, sagging down as jizz gushed out of the trembling lion's hole, his legs going stock-straight as he couldn't help pushing out a few gooey ropes of seed.

``Ooh, fuck,'' the lion whimpered, before clenching as firmly as he could, keeping the rest inside him. He could still feel some of his student's jizz spilling down his taint and furry balls, before making a mess of both his desk and his floor.

Murray stopped recording once the torrent of leaking cum had stopped and the lion stopped waggling his hips teasingly, chuckling and blushing as he took a few more pictures of his teacher's ass. Then, he set it down on the desk again. ``Good thing the janitor already saw us, I guess...'' he commented, making sure not to step in the cum as he helped Pueres down from the desk.

The two quickly cleaned up as best they could, leaving the mess of mouse and lion jizz on the desk and floor. Pueres was a bit annoyed about how much he'd gotten on his shirt, but once it dried he just held his bag in front of his chest to hide it from view. Murray tucked his softening mammoth of a dick into his pants again, helping his teacher get his pants and underwear back on without gushing more cum out.

There,'' Pueres sighed, buttoning his pants and letting himself relax a bit. He bit his lip and blushed as he felt more still-warm mouse cum spilling out into his boxers, but ignored it for now.Ah... we should get going, then.''

Right!'' the mouse nodded, blushing as he scooped up his bag. Then, as the two were heading out the classroom door, he added,Um, and, uh... if you want, I'd be down for a... I guess, double-date thing? With you and your boyfriend, me and mine.''

The lion gulped... and nodded. ``I think we could do that, yeah...''
