#4 of Kinktober 2021

And day 4. Decided to go with a pair of characters that I have a fair bit in mind for, but haven't really posted any of: Taurun the bull, and Murray the mouse. They tend to have a sliding scale of jock and nerd energies, but that usually just means I play it up more or less depending on the story idea. For this one I kind of think of it a bit more heavily then usual, though I probably could have played that element up more in the main parts of the story. Oh well. They're probably... mm, late high school, early college in this? I didn't really pin down a specific age/time.


Bimbofication / Cockwarming / Collaring

``Mom, I'm home!''

The mouse stepped into his family's apartment, looking left and right. He was a stereotypical picture of a nerd; small frame, big-rimmed glasses, sweater vest, anxious expression. He even had a pencil tucked up on one of his big, round ears. Murray, for that was the mouse's name, glanced around expectantly, leaving the door open for a moment. And, when no reply call came from his mother or father, he turned back to it and called, ``Nobody's here! C'mon in, Tau!''

If the mouse was a picture-perfect nerd, then the bull was a picture-perfect jock. Tall and broad shouldered, handsome with pearly horns and a square jaw, hair swept back. He even wore form-fitting jeans and a varsity jacket, green and black with the name `HORNMEYER' written on the back.

``Heh, cool,'' the jock nodded, shutting the door behind him and slipping his backpack off the one shoulder it had been on.

Yep!'' the now-excited mouse chimed, reaching out and grabbing the bull's free wrist.Now, come on! We might not have the house to ourselves for long!''

``Haha, alright, alright,'' Tau, the bull, answered, letting himself get tugged along down the hall to Murray's bedroom. Jock and nerd entered, and the anxious mouse closed the door behind them, letting the bull shuffle in and drop his bag on the floor next to his desk.

The mouse leaned back on the door, and let out a low exhale. Then, looking at the bull, Murray said, ``Alright... Strip, big guy.''

Now it was Tau's turn to blush, gulp anxiously, and nod. He pulled off his jacket and threw it over the back of the mouse's desk chair, before taking off his shirt and throwing it on the floor. His jeans went next, and he blushed as he now stood in just a jockstrap, muscular ass on display as he stood half-naked.

``Right, now... M- My turn,'' the mouse declared, shuffling deeper into the room, a blush on his cheeks but a more confident look in his eyes as he pulled his vest and button-up shirt off in one swoop, awkwardly adjusting his glasses to keep them on for now, before dropping his pants. Unlike the jock, he wore a pair of plain white briefs, tightly hugging his slightly chubby waist, his unathletic belly having a slight bit of jiggle to it as he stood half naked in front of the watching bull.

The mouse reached into his dresser momentarily, and tugged out a sturdy, leather collar and leash, which jangled. ``S- Sit on the bed,'' Murray ordered, gesturing to the small, messy bed in the corner. Tau blushed, and nodded, walking away from the mouse (who was most definitely staring at his exposed ass). He turned and dropped his bare rump onto the bed, blushing and gulping as he looked over at his partner.

Murray once again just watched a moment, before walking forward. The elevation of the bed was such that, when he got to the bull's spread legs, their groins were at equal height. And, as the mouse nestled against his bovine companion, another difference between them was made clear. While Tau's bulge was far from small, maybe even a bit above average... the mouse's was beyond compare. Immense testicles sagged his briefs, an impossibly fat cock strained the front of the white underwear.

At the unexpected but more than welcome comparison, Tau shuddered and mooed softly, his jockstrap visibly tenting up. ``F- Fuck...'' he whined softly, one hand back on the bed for support and the other moving to settle on the mouse's hip.

Murray also blushed and grew a bit more erect at the close contact, huffing lightly as the already-strained briefs grew tighter. But, he had a goal, and reached up to grip one of the bull's horns, tilting it down so he had easier access to the larger male's neck. Tau shuddered but didn't object, lifting his chin and lowering his body so that the mouse could loop the leather collar around his throat. It clicked shut and was cinched tight, the bull's hooved feet curling slightly in pleasure. Then, the leash was attached, and he leaned back up, blushing and smiling at the smaller male.

``H- How does it look?'' Tau asked, chuckling lightly. He could feel his partner's erection throb in his pants.

Fuck...'' the mouse sighed happily, gripping the leash in both hands.You look so good...''

``Hehe, thanks,'' the bull answered, squirming on the bed.

Murray stared a moment, eyes tracing from that handsome, loving face, down to the sturdy collar around his throat, and further, drinking in muscular, heaving pecs, firm abs, and the bulge in his jockstrap. God, this guy was perfect.

The mouse put on a confident smile, humming softly. Then, he gave the leash a firm tug, Tau mooing in surprise. ``Now, c'mon, we don't have long. Hope you've been stretching, big guy, cuz we don't have time for foreplay tonight!'' Murray declared, all trace of anxious trembles in his voice gone. The bull shuddered at the commanding tone, and nodded.

Soon, the bovine found himself laid on his back on the bed, arms spread out beside him and legs lifted into the air. The mouse kneeled at his rump, briefs still bulging obscenely and leash still in hand, albeit loosely. Murray didn't speak, simply reaching a paw down to shove his underwear down, finally exposing his immense cock to the air. Musk filled the room immediately, the smell of his dick making the bull moan happily, his own bulge twitching in his jockstrap. Fat balls, each the size of a fist, sagged low between the mouse's legs, while a beer-can-thick cock bobbed in the air, drooling a profuse amount of precum onto Tau's body. And it was, of course, long as well as thick, easily a foot in length now that he was fully hard.

Tau couldn't help but moo excitedly as his leash was tugged, automatically tucking his legs up higher to give better access to his muscular ass. The mouse stuck the leash between his own teeth, holding it while his paws reached down and spread those plump, firm cheeks. And nestled between the larger male's ass cheeks was the round, rubbery base of a butt plug, firmly planted inside the jock's ass.

The bull moaned as the toy was teasingly twisted back and forth in his hole, shuddering and visibly oozing pre into his jockstrap, the once-light pouch turning dark as his fluids leaked into it. Then, he cried out as it was tugged, the mouse pulling it firmly and steadily, watching it stretch his pink, puffy ring. Finally, with a wet pop, the huge anal plug came free, Tau whining and sagging into the bed again, panting and whimpering as his glistening, gaped anus tried to wink shut.

Murray removed the leash from his teeth, holding it in one paw and giving it a firm tug. ``Grab a condom, big guy, and some lube,'' the mouse ordered, catching his partner's attention. The bull blinked, and then nodded hazily, twisting his upper body some to reach into the headboard's open compartment, shifting some books out of the way to snatch up a small bottle of clear lube, and a single remaining condom.

``Uh, l- looks like... we might need more soon,'' the bull informed as he handed over the two items. The mouse nodded, setting the lube at his side before tearing open the condom wrapper with his teeth.

``We'll leave that to later,'' Murray answered as he got out the condom.

Then, he expertly settled it at his fat, humanoid tip, and unfurled it down his length, the jumbo-sized condom slipping on with ease. In moments, his whole cock was covered from tip to base in the pink-ish latex covering, which he then immediately lathered it in lube.

Leash in one hand, immense cock in the other, the mouse got into position. He rolled his hips back, angling his fat prick at the bull's puffy anus, smearing some of his lube on the gaping hole. He kept the leash firm, listening to the big, muscular bovine pant and whimper desperately, legs trembling and bulge twitching.

Murray probably could have just slammed in, but he opted to go slow. Pressing steadily, he licked his lips eagerly as he watched his partner's plump anus spread open easily, the bull mooing in pleasure and squirming as he was slowly penetrated. The mouse shuffled a bit closer, working himself deeper and deeper, watching and feeling inch after inch of his fat, throbbing cock sink into warm, bovine ass. Just loose enough to fit, but still tight enough to squeeze at every bit of his dick, and so pleasurably hot that it made the mouse's head swim.

Finally, he got balls deep. Tau moaned, his fingers digging into the bedding and his body trembling with pleasure and anticipation. Murray smiled lovingly down at his partner; he loved the noises the larger male made when he was fully sheathed in his ass, loved the panting and the grunting and the mooing.

Speaking of...

The mouse kept his knees planted on the bed, rolling his hips back and peering down briefly to watch the glistening, condom-wrapped cock pull back. And, as it receded from the bull's ass, that needy hole clung to him, tugged out as he pulled back.

Ooh, fuck... Babe...'' Tau whined, his eyes pinned shut and his square jaw slack. He mooed sharply and happily when the nerdy mouse slammed in, those immense balls slamming into his rump with a wet plap.Ah! M- Murray, oh fuck!''

That's right, big guy,'' the mouse cooed, gripping one of the bull's knees and tugging at the leash firmly. He began to steadily thrust in and out, wet squelching and happy mooing filling the air alongside his own overwhelming musk.Mmf, say my name, big guy... Mmf, moo for me, hehe!''

The bull mooed. He moaned. He grunted and whined and panted out Murray's name, shifting from loving to desperate as time went on. The mouse leaned over his partner's body, keeping the leash taught and giving it a few firm yanks when he didn't think the bull was being noisy enough. His heavy nuts slammed into Tau's ass, pounding into his jiggly flesh as the slightly tubby rodent railed the larger male. Their grunts and moans and scents blended together.

Tau reached a sudden crescendo, desperately whimpering out Murray's name before mooing sharply, head thrown back as his partner pounded his ass. The mouse chuckled, grinning as he peered down beneath his own belly to see that the bull was cumming hands free in his jockstrap, pearly bovine seminal fluids welling up and spilling through the cloth pouch.

Murray settled back, turning to a few slowly, shallow thrusts as he reached a paw down to grope the cummy jockstrap. He could feel his partner's cock already going flaccid, the whimpering bovine squirming and shuddering at his grasp.

``Mm, that's a good boy!'' the mouse praised, giving his bull's softening shaft a squeeze through his underwear.

``Ah... Th- Thank you... Mmf, thank you...''

You're very welcome,'' Murray chimed back, before giving the leash a tug.Mm, but I didn't cum yet! How's about you get onto your side, big boy?''

Tau whimpered and shivered as his partner slipped that fat, twitching cock out of his gaping ass, another soft moo leaving him as the over-sensitive, puffy anus was teased by inch after inch of rodent dick. The bull rolled onto his side, pressing his muscular chest and knees up against the nearby wall, his paws settling on the wall as well for purchase.

Murray, leash still in hand, flopped down beside the larger male, wincing a bit as he nearly toppled over the edge of the bed; it was a bit too small to be doing this, but he didn't care. The mouse nestled up behind his partner, nuzzling and kissing at his shoulder blades as he began humping, grinding his cock between those muscular cheeks and across the bovine's gaping anal ring.

``Ooh, fuck...'' the bull whined, his hips rocking back against the mouse's thrusts. Murray chuckled, giving Tau's back a loving kiss, before giving the leash a tug and reaching his free paw down to line himself up.

The bovine bottom mooed again when he was penetrated, this time all in one firm thrust. He arched and shuddered, panting as the mouse took a firm grip of his hip, the other yanking his leash hard. Murray began to thrust again, hard and fast, the sounds of his partner's moaning and whining urging him on.

``Ooh, fuck, fuck! Murray! Oh, god, you're so- Fuck! Big!''

The bull's mindless words grew louder and louder, sharper as the mouse nestled against his back and nipped at his thin-furred flesh, grunting and panting with the effort. The new angle made it hard for his balls to swing down against his flesh, but he made up for that by pounding even harder, hips plapping loudly and wetly against the bull's plump, muscular ass. His fingers curled around the jockstrap's waistband, his toes curling and flexing as tight, wet bovine anus caressed every inch of his throbbing dick.

``Mmf, here it comes...'' the mouse grunted out, eyes screwed shut and leash taught as he railed the larger male. His furless tail curled around his own thigh, balls contracting as orgasm approached.

``F- fuck, cum in me, Murray! Ah, I need it! Fill me with your seed!'' the bull groaned, starting to once again thrust his hips back to meet the mouse's thrusts. Murray grunted, fist tightly gripping the leash as he thrust, and thrust, and thrust, and-

``Fuck!''

Murray slammed in one last time, sinking balls-deep into the bull once again. He didn't cry out or groan like the bull did; instead, he just tilted his muzzle down, pressing his forehead into the big, muscular bovine's back, shuddering and arching his hips up into that slick ass as he came. He whimpered softly, glasses askew and lips trembling as he orgasmed inside the bovine; he was sure that, as usual, the condom was being swelled up like a balloon by his copious climaxes, stretching his partner's insides in a way that made Tau moan happily once again.

He was sure he was still spurting rodent jizz into the condom. Even so, Murray sagged, panting into his partner's back and nuzzling into him. Mmf... fuck...'' the nerdy mouse sighed, weakly releasing the bull's leash, arms curling around his middle.God... that was so good...''

``Ah... F- Fuck... so good...'' the bull panted back, squirming back against him.

The smell of semen and sweat was still flooding the air. Shakily, Tau reached up to the window above the bed, cracking it open slightly in the hopes of airing it out before the mouse's parents got home. Then, he flopped back down onto the bedding, eyes slipping shut tiredly.

Mm...'' the mouse sighed, hugging himself against the big bull, giving another light smooch to the other male's back before settling comfortably again.We can get to work on that homework later...''

Heh,'' Tau chuckled weakly, wiggling back against his partner. He could feel the mouse's softening dick inside him, clenching a bit but content to serve as a cockwarmer for a bit.Alright, babe...

``... Hey, Murray?''

``Mm, yeah Tau?''

``I love you.''

The mouse smiled sleepily, setting his head against the bull's back instead of the pillow. ``Love you too, babe.''
