Adam massaged his thick sheath, fingers kneading its dark folds, revealing the flat head of the monstrous cock inside. His equine lips pulled back over his teeth as he nickered lustily. He needed this. He needed the release. Practice was a mess today, his team was all over the field. His hips shifted so that his heavy dark-skinned balls rolled off the edge of the slatted wooden locker room seat, his jewels dangling precariously above the tile.

“Jeez, man... do you have to take that thing out every time?" Jessie snorted with more than a little derision as he turned towards the horse, dragging a hole-filled white T-shirt over his antlers onto his chiseled torso. Tufts of his fur spilled out of the jagged tears across his chest, sides, and back. The whole team rolled their eyes and chuckled every time he insisted on putting it on, refusing to use button-downs like most horned species had used since time immemorial. Despite its raggedness, the shirt was still surprisingly tight-fitting on the deer, framing his abs and pecs like it was painted on. The shirt's hem stopped well above the deer's naked lower torso if anything framing the region between his legs all the more starkly. 

“Heh. Aren't you one to talk; I saw you in here with Angie last week," the horse retorted, an innocent smile on his long muzzle as he turned to face the deer. His thick fingers delved into his sheath without missing a beat.

“He's right, you know," Brad chimed in, his gray-white leopard tail swishing behind him as he hopped on one paw, trying to get his running shorts over his free leg. “Coach said we are missing...urghh... pizza Fridays for three weeks because of that little incident," the cat growled as he hitched and wriggled the shorts over his lithe feline hips. “And I really liked pizza Fridays," he stated matter-of-factly as his paws delved into his pants to adjust his small, tight package, before pulling his long tail through the designated hole in the back of the shorts. He let out a soft grunting mewl as he made the final adjustments to the garment before dragging it up over his compact, rounded butt cheeks.

“Yeah, well!...It wasn't that bad," Jessie retorted, deflating. His bravado was rapidly fading as he grimaced. He did his best to shrug off his team's collective and ongoing derision. He didn't care about what they thought, he told himself, as he did his best to speed up his dressing process. Turning back to his locker, he angrily rustled through his things as he looked for his keys.

“Yeah, Angie! The janitors said...they said that they had to get her milk out of the ventilation system! The ventilation system!" Riley snickered.. “It took three days!!!" the fox guffawed, unable to stop himself from laughing at the incident, his lungs gasping for air “Three days!!!". The fox's laughter carried across the locker room, becoming mildly infectious as various teammates joined in. Jessie was stewing, the laughter just made him angry.

“Let the captain have his fun...." Nathan growled silently to himself as the room laughed at the deer's escapades. He couldn't hold back a blush as his meaty cock began to peek out of his exposed, heavy sheath. He was across the room, but his rounded ears could hear the conversation just fine above the din of his teammates laughing, talking, and dressing. Teammates that had also made fun of him more than he would like to admit at various times in the season. They said it was all in good fun, but it still hurt sometimes. Despite his size and species, he was the most self-conscious and soft-spoken member of the team. His body stood higher than everybody, except the equines and Roger, their obligatory team rhino. Nathan's eyes darted guiltily downward towards the throbbing tip of his malehood poking out from between his legs. He quickly cupped it with a wide paw, trying to hide it. He always got like this when he thought about the captain.

Adam was content to let the drama unfold around him as his cock snaked out of his equine sheath. Its girth throbbed as inch upon inch poured out of him, his soft equine fleshing flopping towards the floor.

“Aw, screw it," Jessie huffed as he threw his pants over his shoulder. He didn't need this. With little more on than his shirt and jacket, he stormed out of the dressing area, his sheath jiggling as his orange-sized cervine balls slapped between his legs. They all watched him leave, collectively chuckled, and returned to what they were doing, the temporary silence broken. They all knew, and Adam had made it perfectly clear, that even though he was a bit of a jerk, he was their jerk. Nobody was too worked up about losing pizza night except for Brad anyway. They could do without the carbs and Angelos was getting old. Nobody was going to tell Jessie that though.

“Okay, see ya next week guys!" Chuck, the black-furred stallion, chimed in as he slapped Adam's broad, bare shoulder. He was about to depart himself, a pair of extra-strong jeans conforming around his substantial lower body. “Wish I could stay around to help you with that. I know how it is," the horse commiserated, as he squeezed one of his pendulous obsidian balls through his jeans, letting out a low lusty whinny as he directed a none-too-subtle wink at the captain. “Got a date I can't be late for, and knowing you... I would be... very late," the horse smiled. 

Being the only two horses on the team predisposed him and Adam to having fun off the field occasionally. It was an unwritten rule that horses stuck together on their campus. Occasionally, when they were both especially horny, they put on a show for their other teammates. The two started pretty tamely, the normal stuff... crossing their erect cocks like swords until Adam inevitably won the day and bred him, seeing who could last the longest without nutting, and so on. Brad had suggested they use some toys to liven things up. And they sure did. Soon after the toys' introduction, their sessions began to get out of control, increasing in length and intensity. The whole team missed their call to the field because the changing room had become a giant orgy of clacking hooves, grasping claws, clenching balls, and lustful roaring, and to top it off, an unimaginable amount of cum. There weren't any toys allowed after that.

Riley, their team's fox player, to this day could be given an almost immediate and powerful boner when anybody brought up “tennis balls", a favorite stimulation aid among the larger species. Riley's reaction was near Pavlovian. Chuck had once made the slender fox cum uncontrollably by whispering it into his triangular ears just before they skirmished. It wasn't immediate, but soon Chuck couldn't stop laughing as the fox's paws struggled to hold the ball, his cock peeking out of the top of his shorts while he began to uncontrollably cum, doing his best to sprint across the field. It didn't matter that it had caused them to forfeit three points on a foul. It was worth it to see the fox's throbbing, tapered dick bobbing wildly, and comically, between his thighs as his shorts rolled down over his hips, revealing the throbbing member.

Eventually, Riley staggered and crumpled into the grass, his uniform's lower half wrapped around his knees, a gasping, shuddering, orgasmic mess of fur and moaning. The whole team gathered around him, marveling at what an impressive job Riley did of coating his sharp muzzle and their ball in slick, yellowish fox seed. They had to get the equipment guys to get them another ball. Though some on the team thought it would be funny to keep playing with the jizz-covered one, the referees disagreed.

Coach, surprisingly, didn't seem to mind that much, ahead in points as they were that game, as long as they didn't do anything to jeopardize the playoffs. He said that it helped to build team cohesiveness when he caught teammates joining at the hip. It didn't hurt that Chuck liked getting skewered by Adam's massive tool in front of his whole team either.

“Heh, don't worry about it. Have a *nnhhhnnhh* good weekend, Chuck." Adam smiled back at Chuck between increasingly heavy breaths, waving him off with one partially pre-cum covered hand before returning it and his attention to his tool. 

One by one, his teammates left, some in various states of undress, as Adam slowly massaged and stroked his shaft. The university had a fairly liberal clothing policy, but it did frown on too much public masturbation or intercourse. Adam had already been given a few warnings by campus security that he was disrupting classes with his post-practice stress relief sessions. He preferred to do it in the locker room these days; it wasn't worth the hassle.

Adam huffed; he was having a hard time getting himself hard, his flaccid member unresponsive to his kneading hands. The pressures of leading the team were wearing on him despite his efforts to hide it. He felt like he had lost something, but he couldn't say what. “Aww…come on," he moaned as he hefted his still frustratingly flaccid tool in his hands. His wide urethra could barely even manage a few drops of pre, its copious flow staunched by stress. 

Adam didn't notice the large brown bear hesitantly standing in front of him until his shadow cast itself over Adam's dangling cock.

“H..hey…do you… I was wondering…If you…you need some help?" Nathan said with a stuttering shyness, his voice cracking despite its rumbling depth. He had never been so bold as to offer this kind of assistance to the captain. Other teammates did it with such ease, and Adam obliged them all. Most had worn themselves out before Adam had even gotten close, though. He wasn't sure why he had gathered enough courage to ask Adam if he could join in today. He wasn't sure he could do any better. He couldn't explain it to himself; maybe it was the throbbing in his loins, or how Jessie had talked to Adam earlier, but today of all days Nathan felt like he needed to go for it. He swallowed hard as he mustered his courage.

Whenever the team played with each other after practice, Nathan was always the most embarrassed, and the most hesitant to join in. His teammates' libidos and casual intimacy with each other intimidated him. If he couldn't manage to sneak out, he would find a corner near the showers and stroke himself off while the others had the fun. 

The captain was always the most intimidating to him, by far. It wasn't the captain's fault though. Adam had always been especially kind to him, despite his uncommonly meek disposition. The horse always had such ease and grace with social situations that Nathan could never hope to achieve. Not to mention his wide popularity among his fellow players, and the university as a whole, nothing could touch the horse's stature. It didn't hurt that Adam's chiseled toned equine body and tight, huge package were a good bit larger than all but the largest species on campus. Even Chuck, for all his gifts, couldn't hold a candle to what their captain had been endowed with. Adam was on a golden pedestal to Nathan. He never felt quite worthy of even being around him, let alone on the same team despite earning his place over and over again on the field. The way Adam carried himself, his confidence made the bear weak in the knees but also inflamed something deep inside him. Despite all of this, he stood in front of the sitting horse, his...his idol, baring himself whole, his dick throbbing from anxiety beginning to hang from its furry sheath.

“Hey!" Adam whinnied in surprise, his body involuntarily jerking backward as realized he wasn't alone, his long face tilting upward to look at the bear with his piercing blue-green eyes. “You scared me, Nate! I thought you had left with the other guys," he said as he regained his composure, his body resettling on the bench.

“Honestly, I am surprised…" The horse's eyebrow rose inquisitively as he sized up the bear's entire body. He shook his head and smiled, “We never have done it, have we, Nate?". Nathan could feel the horse's deliriously brilliant eyes piercing through him as Adam looked him over, lingering especially long on his growing anxiety boner. 

“NO!" Nathan interrupted with an unintentionally loud shout. “No, I mean, we haven't…at least, I don't think we have...I would remember, not to say I would forget, and….." The bear rambled nervously. His anxiety boner was getting worse as a couple more inches throbbed out of his sheath.

Adam wordlessly reached out and placed one thick-nailed finger on the dangling, domed tip of the bear's cock. Nathan immediately stopped talking as his whole body shuddered from the touch. “Aaahhhhhh!!!" Nathan moaned uncontrollably, electricity arcing down the length of his manhood down into his heavy balls.

The horse spread his thighs, giving Nathan an even better view of his dangling package. “Honestly, I am surprised, Nate." The horse smiled suggestively at him. "Surprised it's taken you this long," Adam's long lips pulled back over his white flat teeth. Nathan felt like a thousand pounds of nerves lifted off of him at those words. “You have your work cut out for you though. Get to it," the horse beckoned, gesturing towards the meat between his legs.

Nathan wasted no time sinking to his hands and knees. He found himself shaking in a mixture of anticipation and fear. He wasn't sure he could do this, now that he was facing the task in front of him. He shook his head to try to clear his thoughts. He was shy, but not inexperienced. In his hometown, he had taken and been taken by many of the smaller species that inhabited it. His family was the only bears for a hundred miles so he had to make do with his share of foxes, rabbits, and even groundhogs as mating partners. They had endurance, he would give them that, but their size was never enough for him. He was always afraid he was going to break one of them in half with his member. Only after being exposed to all the amazing and new species in the university did he get some perspective on how diversely hung the world was, and start to understand what he was missing out on all this time.

Nathan's broad muzzle kissed the top of the stallion's cock as his nerves began to calm, his paws attempting to roll the horse's massive dangling balls in his palm. He could do this, he told himself. He let out a low moan as he marveled at the orbs; they were too large for even his large, ursine paws to fully grasp. Their weight felt immense; he wasn't sure how the captain could walk with these things, let alone play as well as he did. Despite their relative proportionality to his body, these balls were something special. And now...and now Adam was offering them to him. He couldn't help another low growl escape his throat as he massaged the massive nuts, alternating between each testicle, letting the rough contours of his paw pads caress their sheer, taut skin. Nathan wasn't sure the horse's scrotum could hold one more cubic centimeter without bursting, the skin was so tightly wrapped around the melon-sized testes. Nathan ran his padded fingers between them, delving into their deep cleft, feeling their immense heat on his skin. The bear was having a hard time concentrating; the musk and sheer eroticism of Adam's cock and balls were overwhelming, both demanding his attention. His large ursine body did its best to service the horse above him as his heart raced in his ears.

Adam couldn't help but nicker lustily as pleasurable electricity arced through his sensitive orbs. His flaccid cock began to come alive as inches of additional length spilled out of his sheath. His penis began to harden as it engorged with new, hot pulses of blood. It had been weeks since he had felt this way; shivers of pleasure pulsed through his growing member. There was something undoubtedly hot about having a teammate he had never coupled with go down on him. Adam, despite his intimidating body, never forced anybody on their team to do anything they didn't want to do, at least off the field. And it was paying dividends now as the rough tongue of the bear dragged along his length.

“Don't…don't…ughhhh…stop, don't stop," Adam moaned as his hands gripped the bear's soft head fur, his strong arms pulling Nathan's muzzle against his crotch. "Urghhhh...uhnnnnn," Adam groaned lustily, foam starting to form at the edges of his mouth as his medial ring pulsed. His massive length bobbed between his legs at the bear's needful licking.

“Don't..don't need to tell me..twice," the bear gasped, coming up for air halfway through his sentence before sinking his muzzle deeper between Adam's legs. Nathan's large, wet nose breathed in the horse's musky, equine scent as his muzzle worshipped the horse's cock.

Nathan slurped at the massive rod with his wide, rough tongue, leaving a treasure trail of his saliva along its length. He could tell Adam was excited, as his near flaccid cock was now standing at full attention and leaking small beads of yellowish clear precum. It throbbed needfully in front of him. Nathan had seen some cocks in his life but had never been so close to something so erotic, so powerful, so large. Seeing it from a distance was nothing like seeing it up close. He could feel the rampant heat coming off of it on his face. It was beyond glorious.

The bear couldn't stop himself, even if he had wanted to, as his muzzle began to open to take Adam's length into himself. Thick strands of saliva dragged between his large ursine teeth as he opened his maw. The bear proceeded to attempt to choke down the impossibly huge column of horse cock. He had never given head to a horse before; he felt like his jaw may dislocate as he pressed inch after inch into his mouth. He wanted this so badly. His bear cock leaked like a faucet between his legs.

Adam was enjoying the thorough cleaning downstairs so much that he was shocked to see the bear trying to deep-throat his tool. “That…ahhhhnnn…may be a little advanced…for you," he managed to moan between orgasmic surges of pleasure as the bear's muzzle wrapped around his cock's sensitive, flat head. Adam's partially braided tail swished behind him as he settled backward on his thick equine butt cheeks, letting the bear attempt to take him.

“Dnth wrrry…I goth…uhnnn.. thith," the bear managed to gurgle out in muffled response as at least six inches of horse cock pushed into his over-stretched muzzle. Nathan wasn't even close to getting the medial ring in but still, he persisted. He backed out and tried again, saliva and pre-cum spilling from the sides of his mouth, his wide black nose flaring as it took up breathing duties. 

“Oh god, Nate….you give…good head," Adam huffed, his body shaking in increasing ecstasy. “Ohhhhhhhnnnghhh," the horse neighed deeply as his cock's medial ring finally disappeared into the bear's maw. He was impressively halfway there and showed no signs of choking. The flared tip of his tool had made it past the back of the bear's throat, inching down his esophagus. Adam's cock surged as it splattered and lubricated the length of the bear's throat with his scalding hot, equine precum. Adam couldn't help it as his hips began to thrust and gyrate, pulling and pushing his cock in and out of Nathan's gaping mouth.

“UHHHH..UHhh...hhhhhng...hhhhhuhh," Nathan moaned between gasping breaths. The equine precum sliding down his throat was pushing him over the edge; it tasted like intoxicatingly sweet molasses. It filled his senses; his eyes rolled backward. Adam's cock pressed in and out of him. This was as much of Adam as he could take in his mouth, just barely past halfway, but it was enough. 

“Ahhhh….ahhhh!!! HRRNNnnhhhh…" Adam groaned. He felt so close, his balls were tensing in their sac as they dropped lower. The hard-packed flesh of his cock tensed as his urethra bulged. He was almost ready to explode. Suddenly a light nip of ursine teeth on his cock brought him back from the brink. He realized that the large bear deep-throating his member was cumming himself.

Nathan was paying so much attention to Adam's pleasure that he hadn't realized how close he was. His bear cock was painfully erect as it slapped the locker room floor sending a jolt of pleasure up his bulging taint. His eyes went wide as he realized what was going to happen too late. “IMTH CUMMINTH….UUHHHHHH!!!!" He screamed through the horse's cock stuffed into his throat. The surprise orgasm hit him like a tsunami. Shuddering uncontrollably, he could do nothing to stop his long rock-hard cock from beginning to cum between his legs. 

The bear's set of impressively large balls churned and hitched as his thick cock swelled, pushing its domed head into the floor, before letting out rope after rope of his ursine seed across the tile. His swollen taint bulged with his prostate, sending shudders of pleasure up his long spine. His stubby tail flicked back and forth manically. Powerful gales of semen splattered wetly between his front paws, joining the drool and pre that had escaped his muzzle. It took all his willpower to not bite down on Adam's tool as his massive body spasmed. The broad muscles in his back tensed as his furry thighs shook. He wasn't sure how he was able to keep himself from collapsing onto the floor.

“Hnnhh..I…thought you could hold out longer Nate…Don't worry, we can still have some more fun," the horse gasped through hot heavy breaths. He felt the sticky webbing of Nate's load on the fur above his hooves. Looking down past his throbbing groin he saw that a good part of the floor was covered in a fan of steaming bear cum. “Pent up?" he smiled a bit at the bear's impressive display. 

Adam knew Nathan had more to give, despite the volume of his ejaculation. Adam had casually observed that Nate had the third or fourth-largest balls on the team. If a jerk of a deer like Jessie could cause a mess with jewels half the size between his legs, Adam was sure that Nate had a fair bit more in him before he was done. 

Nathan reluctantly pulled his head back, releasing Adam's cock from his overstretched esophagus. He was having a hard time keeping the in-and-out rhythm of his muzzle on Adam's meat. The aftershocks of his orgasm wracked his body, the cold of the floor on its senstive, cum-soaked head made the shuddering muscle resume its desperate pulsing. The bear's dark lips smacked wetly with leftover strands of sticky pre and saliva. He wriggled his jaw to try to reseat his bones, they thankfully snapped back into place with a series of pops.

“Hahh….hahh…hhaahh," the bear gasped as he managed to rear onto his haunches, his normally tight balls dragged across the floor, rolling in their loose sac. His eyes rolled in his head as a shock of pleasure erupted through the sensitive orbs, causing him to fully collapse onto his spherical ass cheeks. His thick cock still visibly jerked as a small trickle of cum leaked out of his engorged slit. Nate's large paw pressed on the top of his cock to try to stabilize himself as he attempted to regain some of his composure in front of the captain. “S…sorry…I didn't mean …I didn't mean to," the bear stammered in embarrassment, having a hard time forming words as the orgasm continued to course through his still erect cock. His maleness pressed against his fingers needfully as it leaked jism between his fingers. Even in the haze of lust, more than anything, he was disappointed that he couldn't get Adam to release. 

“Hah! Don't worry about it, Nate," the horse laughed. Despite his demeanor, his cock still raged needfully between his legs as its length pulsed with his massive heartbeat. “You think you can keep going? I think ..hhnnnh.. if I drive for a little while..." the horse gasped as he wrangled the base of his member with his hands. Despite his paw's size, they weren't able to fully get around his full circumference. 

Adam was used to having to finish himself off. Most species around campus had eyes bigger than their appetite for horses. Nathan had been trying so hard. Adam wondered if this was the first time he had been with a horse. If so, it was doubly impressive that he was able to take so much and last so long. There weren't many partners that could take him, let alone hold it together long enough to get him off. Nate didn't succeed on either count, but it was a valiant effort, and Adam appreciated that most of all. Huffing Adam looked at the locker room ceiling, trying to calm himself down.

———————

When Adam reached puberty it hit him like a freight train. He didn't understand why he couldn't keep his eyes off people's crotches as they passed him on the street. His young colt cock would inevitably begin to throb and swell between his thighs as he watched their bits jiggle between their legs. He attracted quite a few stares himself as it leaked droplets of a strange slick, and as he found out later, sweet liquid. 

His first true orgasm embarrassingly wasn't with a friend like most of his schoolmates. Instead, it was his shorts, they had grown too tight on his growing body and rubbed his sheath something fierce as he played catch with his dad one humid summer evening. Adam could do little to hide his hugely swollen cock as it pushed down the length of his pant leg. His dad didn't say anything as the flared head of his penis peeked past the cuff of the fabric and began to coat his shaking leg in his own watery cum. Adam didn't know what was happening and couldn't stop himself from crying between orgasmic moans as his first small load saturated his fur. His dad held him as he rode the waves of unwanted pleasure but left him to clean himself up before they got into the car. They never talked about it.

The lust began to boil stronger and stronger in his loins after that. His parents left him alone for the most part, they were young horses once themselves and understood the changes wracking his body. The roiling need got so bad that he found himself crying out, tearing at his clothes until his body inevitably forced him to delve his hands between his legs. He couldn't stop himself. He hated himself, his changing body for what it was doing. His love of music was growing more difficult to concentrate on. Trying to play the guitar was infuriating, his jiggling increasingly mottled penis tempting his hands. He couldn't even listen to his favorite bands properly without his breathing and heartbeat filling his long ears.

The more his body demanded of him the more, despite himself, he started enjoying it. Adam didn't know when he started reveling in the tightness of his clothes and the heaviness of his still-developing gifts. He dreaded the time alone in his bedroom after dinner each night, dragging his mom's meals out as long as he could. But as his need and size increased he started to scarf down the carefully prepared dinners faster and faster.  His plaintive, frustrated cries in his room at night began to increasingly turn to long neighs of newfound pleasure. All that mattered was between his legs.

A weekly release was soon every day and then every few hours. Almost drowning in the worst of the need, he could drive himself to a raging boner and mind-shattering orgasm by simply looking at his sensitive swollen nethers whether he was wearing clothes or not. Over just a year his cock and body grew immensely. Every time he came his body greeted him the next day slightly bulkier, his balls heavier and his cock a little longer. New thick veins snaked just under the surface of his tool, pulsing and feeding his growing stallionhood. His routine began to feature at least two mind-blanking orgasms before breakfast, often before even leaving his bed. His favorite position, after much experimentation, was to let his massive elongated penis hang below him,  its sheer weight dragging itself across his sheets so that his flaring domed head jammed itself between his pillows. The matted fluffy cushions were woefully inadequate to contain the surging ejaculate but were the closest thing to a tight hole he could approximate in his half-asleep state. So busy with his body, he hardly noticed how his moans grew progressively deeper and more lustful as his orgasms lengthened until his parents embarasingly commented on it. 

The volume and force of the cum in his ejaculate grew along with his rapidly swelling testicles; from a few teaspoons of watery white jism to easily a few heaping sticky cups to something approaching a quart. His hands barely fit around the growing nuts, it was hard to sit with them pressing into his thighs, pulsing, begging for release. Fondling and kneading his balls grew into his favorite pastime when he wasn't able to find full release. He couldn't help but knicker at the tightness of the skin around his testicles that grew with every roaring ejaculation.

Like many horses his age, he grew increasingly intoxicated with his unique sex musk. The smell of his sex caused him to leak an almost steady stream of pre, only making the musk worse. He would regularly taste his cum, whether he wanted to or not. Flat tongue rubbing it over his flat nose and flared nostrils he loved the intoxicating sweet saltiness of it, driving him to cum again and again, strands of his seed sticking to his large flat teeth. 

His previously tidy room became a mess, almost every surface had several ropes of dried cum splattered across it. He was too embarrassed and preoccupied to ask for help. He tried to clean his room himself but he would only wind up cumming again at the smell of himself saturating his room. After returning from school one day he found his mother cleaning off an especially large recent load of dried semen from his much-loved rock posters that hung above his bed. He didn't realize when he was less...sexually active that there was a good reason all the coolest bands' posters were thickly laminated. He made a deal with his mom that she would help him clean up once a week if he would help with the dishes and take out the trash.

His sex-ed teacher, a well-endowed, athletic, and often bottomless bull named Mr. Wilson, explained it was normal to have a “surge" period where a young person's sensitivity and libido went into overdrive. It didn't help that Mr. Wilson's over-thick jiggling sheath and huge balls gave most of the class unwanted boners during the lesson. Boners that Mr. Wilson had each species display for the whole class to demonstrate how to properly use a species-appropriate condom.

Adam was the only horse in the class so he wasn't spared the embarrassment of having his raging mottled cock shown off in front of everybody. He had to endure Mr. Wilson digging through his box for the few XXL latexes while his stallion-hood throbbed and leaked for all to see. He could hear his classmates whispering and giggling as their many eyes made his erection strain even worse. Adam couldn't help but neigh and blush under his fur as he struggled to wriggle the thing on. Dragging the tight elastic down his length he hadn't realized how long he had grown, his fully erect cock almost touching his pecs. The rubber moved over his medial ring to near where his cock met his pliable sheath. It was then he realized that the condom wasn't long enough to wrap all of him, his body shaking while he knickerd trying to force the thinning plastic over himself.

The more he struggled the tighter it got, giving him the sensation of being buried deep in something like he had never felt before.  His worn shorts fell around his ankles before he realized that he was about to cum, unable to pull them up again in time. He couldn't stop himself from thrusting his hips as he unwittingly gave the class a demonstration of the reservoir tip's voluminous capacity. 

Mr. Wilson laughed it off with a joke Adam couldn't hear. He was too preoccupied trying to stop himself from ejaculating and failing spectacularly. Once it was clear he was finally done his teacher helped him remove the condom and tie off the water balloon of cum he had produced. As Mr. Wilson's surprisingly deft hands made quick work of removing the sleeve from his waning cock Adam's eyes widened. The tip of the teacher's much larger tool was beginning to poke its red-pink head out of his sheath. That combined with the way the skin of his sac connected and tugged at his bovine sheath… his dense, pendulum-like balls jockeying for position between his thighs… was making Adam hard again despite his best efforts to hide it.

“Now, don't get any ideas," the bull smiled kindly as he winked at Adam. Mr. Wilson squeezed his substantial sheath so it hid the tip of his chubby before turning back to the class. He went on to explain that they would all enter a “numbing" stage at the end of their sexual surges. Eventually, and Mr. Wilson emphasized it was different for everybody and every species, they would return to a more controllable sensitivity. He then brought several more species up to demonstrate how different cocks required different condom techniques and how important proper sizing was for pleasure, protection, and collection. Adam was thankful that he wasn't the only one to cum from being paraded up front and having a tight latex sleeve applied to their throbbing man parts. 

Mr. Wilson's lesson concluded with the instruction that they all should have as much sexual intercourse as possible to speed up the maturation process and progress to the “numbing". The bull gave them all a bit of time in the last fifteen minutes of class to “acquaint" themselves with proper condom usage and each other while he caught up on grading at his desk. 

Once Adam had paired with a classmate, there among the writhing bodies of his peers, there was no stopping him. He became a sexual machine. Sometimes blacking out for long periods of copulation. Everybody, including his parents, expected it from a horse and his body was overeager to oblige. His enormous nuts, granted he stayed hydrated properly, produced as many sexual fluids as he could use in a whole day of non-stop sex with some masturbating thrown in for good measure. As his body and lust grew his appetites did as well, driving him to find a variety of non-traditional equine partners. 

He found that he had developed a taste for rabbits especially, their tight holes, compact bodies, and truly epic endurance could bring him to orgasm for hours. He delighted in skewering their bodies onto his cock and lifting them into the air with little more than the strength of his raging horse meat. He ground them against walls, posts, anything, and everything as they tried their best to hang onto something. Their lust-glazed eyes as they were fully dominated by him was the most erotic part for him. Their minds were always so easily broken by pleasure. 

Usually, by the fourth orgasm, most couldn't form coherent sentences, by the sixth they lost control of their fine motor functions, and by the eighth, they went into a trance-like state where all they could do was squeak, moan, and cum. He discovered that they could go on somewhat autonomously for a while like that with minimal groping. Adam spent many evenings with his long head leaned up against the well-positioned furry stomach of a recently bred rabbit, using the hare's body like a pillow as he did his homework post-coitus. He reveled in feeling their shallow hitched breathing, the silky softness of their pelt, it was so much better than his actual pillows. The only part he didn't appreciate was the occasional weak spurts of semen that splattered the side of his muzzle from the rabbit's still hard and orgasming phallus.

He took so many rabbit partners that the only ones he still remembered were the ones he brought to a screaming climax in front of his family over dinner. His brothers and sisters grew increasingly fond of them as well, once they saw how much fun he was having with his rotating harem of long-eared but short-lived mates.

Adam appreciated the much larger species as well: bulls, rhinos, lions, and even a giraffe. He learned that he loved to be more dominant with species, especially ones that had an edge on him for size. Despite all his lovers big and small, none could equal his fervor. Adam gained a reputation at school for being the most dominant equine, and possibly person, in his entire class. As the couplings increased in regularity the sex became a blur of bouncing ass cheeks, ball slapping, and frenzied thrusting. Adam didn't notice that his sensitivity was decreasing until one of his partners cried out that he couldn't cum anymore. Adam realized he hadn't cum even once despite painting the otter's insides with pre-cum for more than thirty minutes.

He called his friend Brian over to his house that same night. Brian was a lithe white-furred rabbit who had been one of his earliest and most eager fuck-buddies. But even with Brian's surprisingly tight hole and his deft clenching ass, Adam couldn't cum without Brian exhausting himself on his concrete-hard shaft of male horse muscle. His friend was a gasping, gurgling, moaning mess after their two-hour session. Adam spooned him for a time after that, cupping his overworked balls in his thick hands, forcing him to squeeze the last few reserve ounces of his seed from his flopping shaft. He owed him that much at least. But when the rabbit showed no signs of settling down Adam had to throw the partially comatose, still orgasming and softly squeaking, rabbit over his shoulder and deposit him in his parked car outside to ride out the rest of the night. He had to get some sleep.

Adam's libido began to level off from there, his couplings became less frequent which helped him get his sensitivity to more manageable levels. The need was still there, roiling deep inside of him but it was like somebody had turned down the volume in a big way. He had mixed feelings about it, often missing the pleasurable delirium he had endured for more than four years. The years had left him with an immensely heavy package easily equal to his most well-endowed teachers and students and a body rippled with well-defined muscles to back it up. His libido and endurance had gotten him a top spot on his school's team when a coach spotted him plowing the whole cheerleading squad in one continuous session after a game. His cock had earned him a reputation among his peers that he would not easily shake.

Adam snapped out of his reverie, that was the past. This was now and he desperately needed to get himself off. The strong sex hormones pumping through his blood wouldn't let him stop until he found release. Adam wanted to try Nathan's other hole. Maybe, just maybe, he could get all the way there.

Nathan answered his question with a silent but determined nod. His face was hot and flushed under his fur. His breathing was ragged but calming. He didn't know if he could take Adam, but he was willing to try. The horse stood, his cock slapping his abs as he did so, making him whinny. 

“Get up, Nate, and spread," he instructed. Nathan huffed as he stood. His body felt heavy as he got to his padded feet. The large bear turned around, presenting his rear end to Adam, foot paws sliding sideways on his cum as he did. His orb-like ass cheeks doing their best to spread below his stubby tail.

“You have an impressive set down here," Adam complimented Nathan as he reached a hand between the bear's legs and squeezed his heavy grapefruit-sized balls. His horse cock slid up the bear's broad back leaving a trail of saliva and pre in his fur. “I don't think I have ever had a chance to tell you," he almost whispered, as his large head settled next to Nathan's, resting on his broad shoulder. Despite their species difference, Adam was taller than Nathan. It was an odd sensation for the bear to have another person larger than him so intimate, so close.

“Ahhh!!!" Nathan moaned in pleasurable shock, he hadn't expected Adam to pay attention to his nuts. His body shook in a mix of barely contained pleasure and surprise. “Th…they aren't as nice…nice as yours," the bear moaned, his softening cock beginning to harden again as he felt the horse's thick wrist between his thighs, fingers caressing the cleft between his jiggling orbs. That sensation, along with the feeling of the horse's cock pressing against the small of his back, almost made him cum again. As far as he was concerned, his body was Adam's, to do with as he pleased.

The flow from Adam's cock was truly incredible now as it spurted slick pre-cum like a leaking faucet. Denied its well-deserved release, it was on a hair-trigger. Adam didn't know if he was going to blow all over the bear's back or inside him. He would much prefer inside him. Adam backed away to give himself some maneuvering room, forcing him to release the bear's balls. The hefty ursine orbs sank lower between the bear's legs than when he had started playing with them. 

Adam always liked teasing his quarry before really seriously playing with them, but he wasn't sure how much he was going to be able to do without cumming. The bear was flipping some switches inside him that he hadn't felt flipped in a long...long time. Luckily, he was well practiced at controlling himself, unlike his bear compatriot. He could hold it together until he wanted to with most species around campus. Even so, he didn't want to chance it. Without wasting another breath, Adam began to prod and poke the bear's behind with his flared tool, jamming it into his rounded ass cheeks. 

“Ohhhh…gawwddd," Nathan moaned as he could feel the hard tool jam into his sensitive rear end. “I don't...ahh!!! I don't know if I can…" he gurgled, unsure if he could take a shaft as big as Adam's. “Just…put it in..I can't…it's too much," he finally moaned. He needed it, he couldn't help himself. Tears of growing pleasure began to bead in the corners of his eyes as he used his hands to spread his rear cheeks. Nathan's cock was already at half-mast again, quickly on its way to a full-blown erection. It was the quickest follow-up erection he had ever experienced; his body's latent libido was going into overdrive.

Adam's cock aimed true as it pressed against his throbbing hole, just enough to wet it's surrounding fur with pre. The horse had every intention of entering Nathan, but when he went to push, the bear's pucker simultaneously tensed, causing Adam's gigantic cock's head to slip down the bear's behind on a trail of its slick juices. Before Adam knew it, his cock had slipped between the bear's legs and jammed the back of the bear's balls, his horse cock wearing the bear's testicles like a heavy furry hat. 

"Ohhhhh fuck…." Nathan moaned. It looked like he had two cocks now, his ursine one throbbing in the air, and just below a pair of heavy spread balls, an equine one. “You're…you're huge..I don't know," the bear was losing confidence he could do this as his body betrayed him. His athletic thighs wiggled and rubbed against horse cock. He could feel its thick throbbing veins pushing against his taint. 

“Ahhh, damn it," the horse moaned. He didn't know how much longer he could hold it together. “Hey, let go, I …ahhhgnnnn… am going to nut," he whinnied as the bear reluctantly released him. “Let's..hurghh.. try again," he said with a renewed, animalistic aggression, teeth grinding as he tried to hold himself together. "Get...unnfhhh...ready for it," Adam groaned as he carefully withdrew his cock to finally line it up with the bear's waiting hole. He pushed it in more slowly this time, the wide, flat head of his penis spreading the bear. 

“Please…." Nathan cried as he pressed himself against the horse. His own need was too much to ignore as he did his best to spread himself for Adam. “I'll take it…please… I'll take it." the bear panted.

Adam gave no response except to begin to push his aching cock into the bear's tight hole. Nathan's mouth may have been virginal, but his ass had definitely taken some companions with size as the first few inches of Adam's length slipped in surprisingly easily. However, easy was relative for Adam being as hung as he was. No partner he ever had didn't require some work to fit. But then he began to hit resistance, immeasurable tightness. “NNRGHHHH," Adam moaned as he plowed forward, his body almost tipping the bear over with his powerful legs as he pushed. 

“aaaaAAAHHHHHHH!!!!!!" Nathan growled lustily. He almost fell from the force of Adam's cock. He staggered forward, hands bracing himself against the cold metal lockers. “It's too..too much," the bear moaned plaintively. “You're going to tear me apart." He could feel his insides resisting the intrusion of the log of a cock that his captain wielded between his legs.

“URGHNNNN!!! TAKE IT," Adam neighed aggressively in response, too far gone to stop himself. His body pumped into and out of the bear's curvaceous rump. Wide equine digits gripped Nathan's wide hips as handholds as he fucked the bear with everything he had. More and more of him sank into his deep, dark expanse as finally his medial ring cleared the bear's entrance with a wet *pop*. And then it cleared the bear's entrance again, and again. He delved deeper and deeper, spreading the bear.

Nathan could barely breathe. He felt like his insides were rearranging around Adam's cock. Every thrust of the horse's hips caused his cock to slap side to side, splattering the lockers with his own much less voluminous flow of pre. His balls jiggled akimbo in their sac as he got closer and closer to orgasm. His wide head slammed against the lockers for additional support as he moaned. “Huughhh…ffffuuuckk," was all he could get out of his muzzle as his eyes scrunched shut in pleasure that verged on pain. Tears streamed down his muzzle, making dark trails in his fur.

Adam thrust harder and faster. His pre-lubricated the bear's opening as it gaped obscenely between powerful thrusts. The horse's full, muscular body plowed the bear with everything he had, nearly lifting him off his rear paws as he skewered his teammate. He was so close. So close. With a powerful slam of his hips, he hilted his length into the bear. Their balls slapped together from pendular momentum. “URHHHHHHHH!!!" Adam roared as his testes impacted Nathan's, he could feel their immense weight on his which only enhanced the massive waves of pleasure surging up his entire heaving equine body. His chiseled chest pressed up against the bear's back, their bodies sharing heat as his hands released their grip on Nathan's hips. 

Nathan couldn't do much more than hold on and moan. Adam's left hand slammed against his tensing paw, claws clacking, pressing against the metal locker. He felt Adam's other hand grip his firm stomach, pulling him back onto himself, as he continued to thrust his hilted cock against his opening. Nathan had no idea how he had taken so much and not burst. He could swear that his abdomen was bulging as the horse thrust the column of meat into and out of his abused hole. Despite the initial pain, he was starting to get used to it being in him. The more Adam thrust, the better and better it felt. 

Their bodies ground with animalistic fervor as Nathan began to grind his body back against the horse. His wide hips gyrated as his cock flopped between his thighs. Moaning and groaning incoherently, they were beyond words now. The two became as one, horse and bear, balls and cocks throbbing, the floor under them peppered with their combined male sex juices.

Their thrusting built to a crescendo as Adam's head reared backward, Nathan's muzzle pressed hard against the lockers. 

“NEEEIIIIGHHHHHH!!!!" Adam bellowed as his cock surged in the bear's rump, his cock's head flaring even larger as his urethra swelled. “URRHHHHHHH!!!!" Nathan cried in response, his chest rumbling. Both of their balls hitched in their tightly-skinned sacs, clenching hard as they came together, their orgasm so powerful that it almost brought the pair to their knees. 

Thick ropes of Adam's cum gushed into the bears behind before finding no more room and back-flowing out of the tightly packed hole. Nathan's cock sprayed the lockers and his chest with a series of long, wet splats. Long streaks of the bear's cum painted the dark blue metal of the lockers white. Adam's cock tensed with every powerful spurt of his vast reserves of seed, causing Nathan's abused prostate to throb out of control. Every blast of virile, equine cum into Nathan's rump forced him to ejaculate another scalding rope of jism from his spasming ursine cock. Their bodies rocked together for minutes as Adam filled Nathan over and over, slamming the bear's body against the lockers. Cum spilled out from between their legs, soaking their thighs in sloppy, sticky liquid. Nathan was going numb, his eyes glazing over in pleasure, as his body shook against the cum-coated lockers.

Adam's powerful legs finally gave out as they collapsed into a pile on the floor, both breathing hard, as the orgasm continued to wrack their bodies. Adam held Nathan close as they spooned in their seed. The horse wrapped his muscular body around Nathan's, pressing his hard-packed chest into the bear's back fur. Adam's hands clutched the base of the bear's still-jerking cock, before moving down to squeeze and knead his well-used balls. He coaxed several surprisingly powerful blasts from his waning equipment, coating the horse's thick fingers in webs of jizz. Adam dragged his now thoroughly coated hand up the shuddering ursine's chest and into his gaping mouth.

“Ooooohhhhhhhhh…" was all the bear could gurgle out, his eyes unfocused, as he sucked on Adam's fingers needfully. His body was on autopilot as his hips jerked at the salty-sweet taste of himself. The pair continued to moan and writhe together for some time like that. The sensitivity of their erogenous zones was off the chart. Every small movement shifted the massive, still painfully erect, equine cock buried in Nathan's deepest recesses. Nathan couldn't help but gasp silently, his eyes rolling, his sex daze growing deeper. Webbed strands of Nathan's cum stretched between his sharp teeth before leaking out of the sides of his mouth.

Adam nipped at Nathan's rounded ears with his broad teeth as he nickered, still in control of his faculties, such as they were. Nathan responded with his series of guttural, lust-addled moans, his long cock beginning to dry-heave in ecstasy as its flow began to staunch. Eventually, their orgasms abated, small trickles of leftover cum still dribbling from their softening cocks. The horse and bear both quickly passed out, holding each other tight. The quick session had taken more out of both of them than they expected, and the best sex either had had in a very long time.

The next week, before practice, Adam gave his team a much-needed motivational speech. He felt rejuvenated after his mating session last week with Nathan. The two “ran into one another" again on Saturday, Adam had made sure of it… and again on Sunday…four times. The horse felt that the vigor he had been missing in weeks past had finally returned. He was amped up and he used that to inspire. By the time the team left the locker room, everybody was focused, determined, and ready. Adam stood by the wide doors as his team streamed out.

“Hold up, Nate," he nodded towards the bear as Nathan tried to pass him. Nathan obliged hesitantly, his muzzle looking down sheepishly, unsure what Adam wanted from him. “You okay to go? I know…you had some trouble walking after our last time," he said with a mix of genuine concern and a hint of lust. 

Nathan jumped at that, blushing deeply under his fur. “Y..yeah, I'm okay…" he trailed off. Adam sensed his hesitation and decided the bear needed a bit of a kickstart. He waved the other players past Nathan, as he suddenly stuck his hand down the front of the bear's uniform shorts, grabbing a handful of the bear's soft-furred sheath. He squeezed while pulling the bear closer with his other hand, licking Nathan's face with his long tongue. “Ohhhhh!!! Not..not here, Adam…" Nathan moaned, wriggling himself against the horse. His sheath's length throbbed intensely at the touch, his thick thighs doing their best to try to cross themselves over Adam's powerful grip. His well-used balls jumped as shocks of pleasure coursed through them, almost making him orgasm despite his still-sheathed cock. 

Adam snorted in disappointment through wide nostrils; he hated to admit that Nathan was right. “Well, we still have tonight," he whispered in the bear's ear. The bear's blush intensified as the horse removed his hand from his shorts. “Go show me what you've got," Adam nickered as he slapped the bear's rounded ass cheek. “Ye..yeah, see ya!" Nathan moaned as if coming out of a trance. Shaking his head to clear his thoughts, he knew he had to go before he lost control of his newly inflamed libido. He would have loved nothing more than to let Adam ravage his body again right there and then. He had become addicted to having a horse cock driven inside of him over the weekend; he felt increasingly empty, incomplete without it. 

Nathan was growing increasingly sure that Adam felt the same way. Nathan's paws pulled at his shorts, the sheer sports cloth pulling tight against his swollen package as he left the locker room. He could do little to hide the thickening cock peeking out from under the waistband of his pants as he walked into the hallway that led to the field. His sheath throbbed like a freight train between his legs as his large balls dropped lower in their sac, pulling his uniform down again. He turned back and waved at Adam shyly, giving him an unplanned show before hitching his sagging pants up over the top of his accidentally exposed, bubbly ass cheeks. 

Nathan couldn't stop himself from letting out an uncharacteristically lusty moan as the cloth cupped his heavy testes again, dragging them back up toward his groin. 

“No…uhhnnn…not now," he gasped under his breath. His paws did their best to wipe away the growing beads of clear pre forming on the domed tip of his partially exposed member listing upwards toward his abs. The more he touched himself, the more he thought about him…. Just the thought of the horse made the volume of lubricant leaking from him double, the trickle beginning to matte his sheath's fur in a stream of hot slick liquid. He frantically wiped the liquid off of his sheath. Nathan suddenly stopped as his body shuddered, his head thrown back as his muzzle parted in a gasp. In his haste, the very tip of his index claw had accidentally entered and spread his engorging urethra. “Ffffuu…" he moaned, the skin on his face growing hot as the throbbing in his groin grew exponentially worse. He had to go; he needed fresh air. His pace down the hallway quickened as he joined his raucous teammates, anxious for the distraction.

Adam smiled at the bear as he packed up his gear. He was cute and more than a little sexy. His equine cock was already snaking down the pant leg of his uniform as he started to count the minutes until practice was over…
