Sam blew his whistle to get the soccer team's attention. "All right, troops," he said when all heads were turned towards him, "time to hit the showers."
 
He was a large horse, roughly eight feet tall, with a bit of a potbelly in his advancing years, but he was still very muscular from his days as an athlete. He was the soccer coach at Diogenes High School, a job he enjoyed due to his love of younger men. All of the players on his team were the kind of sleek, fit eighteen-year olds that looked incredibly sexy running around the field in their short soccer shorts and tightfitting pants.
 
One player in particular had caught Sam's eye. A cheetah named Mike. His team's best player, Mike was a natural at the sport and quick on his feet, being a cheetah and all. He'd taken them to the finals at least once, and won them more games then Sam cared to remember in the years since Mike first joined the team. He was also the team's oldest member, at twenty-one. Sam himself was forty-three, but in good health for his age despite his large gut.
 
He stood there, watching the players file past him towards the gym, Mike among them. While walking and talking with his friends the cheetah took off his shirt showing off his toned chest, making the horse coach lick his lips. After each student had walked past him, Sam turned and followed them.
 
He marched them to the showers where he told them, "Lather up, troops. Can't have you going back to your dorms stinking of man sweat." He chuckled.
 
They all went into the showers, including Mike. Sam did not however. He remained in the locker room proper, by himself, listening to the voices of the students echoing off the tiled walls. The reason he did not shower with them was due to his attraction towards them. He dared not sprout a stiffy in front of half a dozen young college students. Granted, he often fantasized that it could lead to an orgy; but he doubted it.
 
So he waited, clipboard in hand, for them to finish. In small groups or one at a time, they emerged from the shower room, some naked, some wearing towels wrapped around their waists. They chatted and talked, and when they were dressed, Sam gave them a brief rundown of the next day's activities before clapping his hands and commanding them to go back to their rooms and sleep. Soon, he was alone. Or so he thought at first. As he went and sat his clipboard down on the bench and removed his baseball cap, he realized one of the showers was still running. One of the students must have forgotten to turn it off, he reasoned.
 
Tossing the cap aside, Sam removed his T-shirt revealing his broad chest and the gut he'd acquired with age. He shook his head, running his thick fingers through his mane. He sniffed under an armpit, and made a face. Rough day today, he thought. It had been ungodly hot and he'd practically sweated through his clothes, so the prospect of a long, hot shower was a promising one indeed. But as he turned and walked into the shower room, he quickly discovered that there was something even more promising to be had this evening.
 
The students had forgotten to turn the water off, after all. Mike was there, naked as the day he was born, with his back to Sam, showering under the running water. The big horse stopped in his tracks. He couldn't believe it. The main reason he'd never "gone" for Mike was because he'd never had a chance to be alone with him. Now, though, he was. Dare he make his move? Mike might rebuff him, and report him for sexual harassment. But still, the horse had heard some talk about the cheetah being gay, and, in the end, he figured it was worth the risk.
 
Slowly he removed his pants and gently kicked them aside. Wearing just his jockstrap, Sam leaned on the doorframe and cleared his throat. Mike turned around, blinking, eyes wide at the sight of his nearly-nude coach, exposing himself fully to the horse. He was un-erect, but his dangling cock was still nice to look at.
 
"Mind if I join you?" Sam asked, his voice soft and deep, seductive.
 
"Actually, I was just finishing up," Mike said.
 
He turned the water off, and for a moment the only sound in the room was the drip-drip-drip of water coming off of the young cheetah's naked form. He grabbed a towel, and began dying off, eying Sam who was making a show of watching every move the cheetah made. Mike then walked over, and stepped past him into the locker room, Sam moving aside slightly to let him by. But....had he just seen a smirk on the cheetah's face? He grinned, then turned and walked after him.
 
Mike, still naked, put one leg up on the bench and toweled it off, slowly. Clearly he was putting on for his coach, who he'd deduced liked him. Sam approached, heart thudding in his chest. He walked around the bench so he could see his star player from the front, and, to his delight, he witnessed Mike's cock in the middle of stiffening and rising up as he took his leg off the bench, then looked up and smiled at the horse.
 
"I take it you were, uh, admiring me," he said.
 
"Oh yes," Sam replied. "I have for some time. But it's been a bitch trying to get you alone."
 
"You're not half bad-looking yourself, Coach," Mike said.
 
A grin spread across his face as he came around and walked right up to the big horse, and gave his potbelly a rub. This elicited a small nicker of pleasure from Sam, who then bent down and softly kissed Mike on the lips, surprised at his own boldness. To his relief however, Mike responded in kind. Both of them hoped against hope no one walked in anytime soon, lest they see the school's soccer coached getting gay with one of his players! Slowly one of Mike's hands slid down Sam's belly towards his jockstrap, but a large hand batted them away.
 
"Ah-ah-ah," Sam said, wagging a finger. "I didn't give you permission, did I, trooper?"
 
"No, sir, Coach," Mike admitted sheepishly.
 
Leaving Mike's side, the horse went and sat on the end of the bench. He motioned with a finger, and the cheetah walked over.
 
"Get down on your knees," he ordered softly.
 
Smiling, Mike kneeled. Sam leaned backwards, lying back on the bench, legs spread. He then sat up, propping himself up on his elbows, looking down his body at Mike on his knees at the end of the bench. From his point of view, the cheetah was framed between his spread, muscular legs. From Mike's, his coach's bent knees are like two huge monoliths marking the entrance to the Garden of Eden; smooth legs terminating into a sweaty jockstrap that bugles with his arousal. And past that, he could see his kind, smirking face over his bulging stomach and toned chest.
 
Sam then brought up one of his hooves to Mike's face, gently. He inhaled, smelling sweat and freshly-cut grass. Getting the idea he took Sam by the ankle and rubbed his hoof over his face, licking it, tasting the sweat and grass and dirt.
 
Sitting up further, Sam reached down and rubbed himself through his jockstrap, mmming softly. His other hoof, until now, had been off by itself to one side. He noticed this and said, "I think my other one is lonely."
 
Mike reached over, groping blindly at the air until he grabbed a big ol' hoof, and drew it over to himself. He clutched it to his shoulder like a security blanket. Gently wrenching it free, Sam smiled and used it to rub the side of Mike's head. The hoof then briefly returned to its perch on the cheetah's shoulder, and then moved lower, down over Mike's flat chest. He sit up a little straighter then, cock harder than ever. It rubbed over a nipple and then went even lower, over Mike's stomach.
 
As his hoof glided down Mike's belly the heel touched the top of the kitty-cock, eliciting a moan from the student. He shifted his position a bit, and then, unceremoniously, Sam brought the hoof up and planted it firmly on Mike's chest, and with a powerful shove the cheetah suddenly found himself lying flat on his back on the cold tiled floor of the locker room, a bit dazed. Sam scooted forwards to the edge of the bench, then firmly planted his left hoof right down onto Mike's cock and balls, and pressed down gently, A sudden groan escaped the prone cheetah. Mike arched his back, ass leaving the floor as he grinded his cock against the hoof.
 
Sam pressed back, the cheetah's lucky dick being mashed gently as the horse slowly forced his butt down the floor again. Eager to return the favor, Mike lifted on of his own legs and slid it across Sam's bare though towards his bulging jockstrap. Kitty toes came into contact with horsecock, and then....Sam suddenly lurched forwards, eyes bulging, feeling a bit funny in his groin. Mike's foot jerked away in response and the cheetah sat up, blinking, wondering if the coach was okay. Then they both heard a soft gurgling noise, and, reflexively, Sam stood, looking down at his jockstrap, wide-eyed, as the bulge suddenly began to get bigger!
 
"What the hell?" Sam managed to blurt.
 
The jockstrap's fabric was stretched to the limit. Hurriedly, Sam took it off, and it fell to the floor, spilling a thick, fourteen-inch horsecock into view. Fourteen inches?! Sam gaped, forgetting about Mike for the moment. At his largest, the horse had been only ten inches! He held the suddenly bigger cock in his hands, and it jerked, and began growing even bigger! Sitting on the floor, Mike gaped as the cock grew, huge and thick, as big as his entire body...and then bigger than that. It finally stopped at seven feet long, as thick around as its owner's torso, Sam gawking as he cradled the mammoth cock in his arms.
 
"Holy shit," he heard Mike say.
 
He looked down, past the cock, at the startled cheetah. And suddenly he got an idea. Sam had always been an impulsive sort who did things spur of the moment, and once he got an idea into his head it was almost impossible to get it out. Which would wind up being very unfortunate for Mike. Without another word, he unwrapped his arms from around the cock. Mike watched as it seemed to come down towards him in slow-motion. The penis slammed into him with all of its weight, knocking the wind out of him and pinning him to the floor. He wriggled beneath the cock like a bug under a shoe, barely able to breathe.
 
The Sam began to move his hips, sliding the thick monster over the cheetah's smaller feline body, and with each thrust, pressing into him a little harder. Slowly he crushed Mike with the weight of his giant swollen dick. The weight of it and the force of its thrusts were so powerful that Sam actually split the floor open, a thin crack appearing underneath Mike, with cheetah lying directly on it from head to toe. Even as cockflesh mashed into Mike's face and filled his vision, the crack widened as his coach fucked him.
 
Sam grunted and kepty thrusting as he towered over the cheetah and dominated him. He looked, and felt, like the very definition of masculine. Male. A thin sheen of sweat appeared on his muscles and roundish belly as he worked feverishly to grind his star player out of existence. The crack widened further, the floor around it crumbled, and, already dazed and weary, Mike fell in. It was a very shallow crack. But it got deeper as Sam's penis fell in after him and landed on him again, and Sam resumed thrusting, slowly pushing Mike down, deeper and deeper, standing astride the crack which did not get any wider, only deeper, ignoring the muffled cries and the weak struggles of the student.
 
By the time he'd ground a hole deep enough where needed to to kneel in order to fit his giant cock all the way down inside, Sam sighed and puledl out, some rocks and chunks of floor tile sticking to the sweaty cock. One by one they fell off, back down into the crack. The horse mmmed and stroked a large hand lovingly over the thick cock, tilting his head, eyeing the fissure he'd created. Then, he came. And he came. And came. And came. And all of it, went down the crack. By the time his orgasm had faded the crack was filled almost to the brim with thick cum. Mike had disappeared completely.
 
Then, as suddenly as it had grown, Sam's cock shrank back to its original ten inches. The coach stood there, rubbing over his once-again normal cock, wondering what the hell just happened. But in the end, he decided it was best not to question it. It had been a hell of a lot of fun, after all. He nodded in satisfaction, and then went and showered. Afterwards, he came back into the locker room and dressed, eyeing the cum-filled crack the entire time. He felt a little bad about Mike, because the cheetah had been his star player. But there were other excellent players on his team, he decided.
 
Smiling, he picked up his stretched jockstrap from the floor, stretched it on two fingers, and then snapped it, letting it fly. It landed with a slimy splash in the cum that pooled in the crack in the floor.
 
The End
