Make An Ass Out Of You!

Dressed in nothing but cotton pyjama pants, the scrawny human man sat at the very top of the stairs. The lights were off, but the glow from the TV downstairs occasionally caught his left leg. He was bouncing it in frustration. It might have been intimidating, but with his small size and the exaggerated scowl upon his face he looked more like a cute, angry purse dog than anything else.
The source of his irritation was his housemates' sloppy behaviour. Upon finishing their second year of university they, Tyler and Roman, had set up a semi-permanent camp in the living room. Ever since then they had been playing video games and watching movies non-stop. In just three weeks, their trash and dirty clothes had accumulated enough to obscure the carpeted floor.
Last night, after snapping at them both for being so lazy, he'd stormed off to relax on his computer only to stumble across an advert. It was some kind of prank beer made to get back at 'beer-bellied layabouts, slack-off dorm mates and duty shirking boyfriends.' 'Jackass Brew' was the brand name.
What it was going to do exactly wasn't advertised but hoping for some petty revenge he had ordered a four pack. It arrived two days later and he had left it outside the living room door as a peace offering just moments ago. Now all he had to do was wait.
It wasn't long before Tyler, the smaller blonde one of the two mess makers, emerged and picked up the package without bothering to inspect it further.
“Thanks, Wes!" He called out before re-entering the living room.
Curious about what had been delivered, he forgot to close the door.
From his position on the stairs, Wes could see the two of them in their nest. Roman sat in the armchair on the opposite side of the room. He was slightly bulkier than Tyler and meaner looking thanks to his dyed black hair, but just as nerdy and just as much of a couch potato. Tyler had taken his place on the closest end of the couch. All Wes could think to describe Tyler as was 'dopey.'
The two were in their most comfortable clothes. For Roman this was a black band shirt with loose fitting night shorts and for Tyler a tank top as well as the jeans he'd put on to get their pizza earlier. He hadn't bothered to exchange them for his own night shorts upon returning.
“Race you." Tyler said with confidence as he tossed one of the beverages to Roman.
The cans hissed as they popped the tops. Quickly, they brought the foaming liquid to their lips and chugged. Wes smirked with an unmistakable eagerness as he leaned in to watch. Their heads tipped back, their throats pulsed, and their legs shook ever so slightly as they both drank the entire thing in just one go. Their cans hit the floor one after the other, first Roman's and then Tyler's.
For a moment, neither spoke and instead just sat grinning to one another before Tyler let out a tremendous burp. Naturally, Roman tried to match it and unsurprisingly succeeded. A moment later and the remaining two cans were in their hands. They took small sips before doing their best to burp louder than before. Wes settled in, trying not to laugh at his friends, as their gross game of bogies continued.
The competition fizzled out when they started watching an action movie on the TV. Falling silent, they continued sipping from their cans as time began to pass them by. 5 minutes became 10, 10 became 15… Wes was about to doze off when a sudden noise rang out:
“Hee-haw!"
His eyes shot open and over to the living room. Roman was mindlessly scrolling on his phone whilst Tyler had fallen into a deep sleep. In this deep sleep, the man had begun to snore and occasionally he would…
“Hee-haw!"
… let out a loud bray.
Roman didn't appear to have noticed his friend's strange noises. In fact he was so unaware that he turned to ask him a question:
“You awake, dude?"
Wes clasped a hand over his mouth to stop himself from gasping. The lower half of Roman's had grown a short, but thick grey beard! Looking on surprise, he slowly realized that it was not a beard, but was in fact a coating of coarse fury. Not only that, but his face was transforming!
Roman's nostrils had flared to twice their usual size and now sat on the end of an equine muzzle, albeit it hadn't protruded all that much from his face just yet. His mouth had changed too; his teeth were wider, flatter and blunter than any human's.
Looking to Tyler, Wes could see that he was beginning to change too. Tyler's face hadn't morphed quite as much, but his feet began to undergo drastic alterations. To the bewilderment of Wes, his housemates' toenails darkened to a shiny black. In just a few seconds they elongated, thickened, and then curved down over the end of his toes. Above these nails, the small amount of hairs he had on his feet rapidly spread to become a coating of fur. Only Wes noticed as the man's toes repositioned, then began to meld into a single hoof on each foot.
They were both becoming donkeys!
When Tyler didn't reply, Roman let out a sigh of relief and stole the remote from his mates' lap. He didn't notice the changes in himself or in his friend and instead began to mindlessly rub at his crotch as if he were appeasing an itch.
“Finally, it's just me and you buddies…" Roman said out loud, most definitely speaking to his junk, as he reclaimed his spot on the loveseat.
Continuing to tease himself, he opened the browser on the smart TV and typed in 'por-.' The autofill gave him exactly what he wanted. From there he began to flick through the pages and pages of videos; painstakingly scrolling down each one without making a choice. Eventually, he selected one and lifted himself up to remove his night shorts.
There was a brief introduction that slowly faded into the porn. Wes could only hear what was happening on the TV, but it must have been good as Roman's eyes were already transfixed on the screen. Not being able to see the porn wasn't a problem for Wes, he was busy watching the bulge in Roman's boxer shorts.
With each passing second it appeared to grow larger and larger. Roman's hand that had been rubbing at the head of his cock was pushed higher every few seconds until it was less of a tent and more of a totem pole. The erection pushed the loose fabric outwards with it creating a clear outline. At the base of his prick, his balls expanded to fill more of the space in his boxers until they were straining the pouch. Wes looked on in wonder; could he not feel the growing heft?
Roman was at least aware of his need to masturbate. Positioning both hands around his underwear-wrapped shaft, he began to pump and hump up into them. With each moan and groan, the transformation accelerated.
The silvery, grey fur on his now donkey shaped mouth stretched over the cheeks of his face to reach his ears, swallowing them. A moment later, two donkey ears sprung up from the top of his head before flopping to cover his human ears which vanished with a blink of an eye. His new ears twitched and jerked in time with his pleasured moans; pleasured moans that roused Tyler.
Immediately Tyler began to grit his teeth. Whatever sexual thrill Roman was experiencing had suddenly begun to hit Tyler. Both of his hands reached for the bulge in his jeans, groping at it only to grant no relief due to his jeans. Huffing, he tried to undo the button preventing him from jacking off, only to find that his fingers had thickened making fine movements difficult. In his struggle, he kicked and thrashed until he found himself kneeling on the couch, facing towards Wes.
Wes, who had now pressed himself to the bars of the staircase banister, received a perfect view of Tyler's straining erection. He had seen his housemates' cocks before and what Tyler was packing now was nothing like his usual equipment. Just by the imprint in the tight jeans, Wes could tell that it had at grown to the point that Tyler's cock head must have been the size of a small, balled up fist.
Tyler might have been able to release himself from his jeans if he were patient, but to him the prospect of waiting to ease his need to masturbate was unthinkable. As his brown, donkey ears drooped down to frame his face; Tyler himself toppled forwards to press his growing bulge against the arm of the sofa. With animalistic lust, he began to hump and grind against the throw trapped beneath his crotch. The firm fabric of the sofa's arm cushioned by the pillow provided just enough pleasure to coax a joyful but needy hee-haw from him.
Shocked, Tyler's hands grasped at his throat. He tried to moan normally only to bray once more. Before concern could set in either him or Wes, Tyler began to smile with glee and began to happily let out donkey noises as he humped away. As his face started to slowly push out like Roman's, he giggled to himself and used his hands to feel the sprouting fur.
A deep snort of ecstasy from Roman drew Wes' attention to his other housemate. Roman had managed to stop himself from touching his cock for just a moment by bringing his hands up to rub at his nipples. He wore a dumb look upon his donkey face, eyes glazed over and slightly rolled as he panted for breath during this brief respite.
He couldn't resist forever though, and neither could Wes. As Roman reached down to remove his underwear, Wes reached for the waistband of his pyjama pants. Although the human's cock wasn't quite as big as his half-donkey housemates', his erection was just as hard. It tented his trousers, begging to be set free. There was no time to waste.
Wes hooked his thumbs through the band of his underwear as Roman grabbed the fabric on either side of the fly of his boxers. Roman ripped as Wes lowered; their cocks sprung out into freedom in sync. Whilst Wes' simply stood to attention, Roman's fat slab of manhood shot up from the tear he had created to slap his belly. Neither of them masturbated and instead stared in reverence at the incredible sight.
It was impossibly large, but unmistakably human with a plump pair of balls to match. That being said, the base was beginning to darken and morph to resemble an equine sheath. Back-dropped by Tyler's whimpering moans and slutty braying, Roman remained perfectly still as his cock continued to transform before his and Wes' very eyes.
A snail trail of grey fur snaked itself from the hidden depths of his boxers. Reaching up his stomach it continued to his pecs. There was a brief pause as for a moment nothing else happened, but when Roman flexed his cock he let out an elated cry as the transformation suddenly surged.
His balls became larger, plumper and rounder whilst his cock grew even longer. Roman tried to back away from it as it went from eight inches to nine to ten and beyond! The precum dribbling constantly from his tip got no closer to the end of his prick as it continually grew. It finally managed to reach the medial ring after a minute of growth. Whilst slumped, Roman was now eye level with the tip of his own prick, the glans of which was starting to shift.
At the same time those inflated balls of his darkened to a coal black. The pressure as they grew sent buttons pinging off, allowing them to slip free with a hefty bounce. The colouration spread to his sheath and the first few inches of his length. The skin of his nutsack simultaneously became leathery and shiny making it easy to see the beads of sweat forming and the pre that had dripped down onto them. The change in colour reached Roman's medial ring leaving a mottled transition from black to a light pink. Wes wished desperately to kneel before him and taste everything he now had to offer.
It was now time for the head of his cock to transform. It grew blunter and flatter, but still maintained a slight curve to it. The ring around his cock head formed, taking on the characteristic bumps of a proper horse cock. It looked exactly like the kinds of toys Wes loved to ride.
Complete and presumably fully transformed, Roman remained still for a moment. His breathing slowed. He began to reach for his cock before it suddenly throbbed hard and grew several more inches whilst spitting out a helping of thick pre cum in celebration.
It splattered against his chest.
The sensation spurred him into grabbing at his balls with one hand and furiously fapping with the other. Wes in turn was snapped back into awareness of his own lust and began to rapidly jerk his own, much smaller, prick.
Meanwhile, Tyler's needs had reached a breaking point. His eyes were shut tight as he bit down on the pillow. One of his hand's had crept behind and was now trying to reach inside his jeans so that he could finger himself. He was having no luck due to how tight the material clung to him. It couldn't have been more than a minute when his desperate whining was suddenly drowned out by the sound of fabric ripping. Halting, Tyler looked back over his shoulder and towards his ass.
The fabric had not only split at the seam, but across the entire ass as well! His expanding rump had applied enough strain that it had torn the back as if they were made of thin sheets of paper. A brown tail, fluffy at the end, peaked through.
Though the sight of a tail delighted him, he was more excited about being able to reach in through the tear and slide a single finger into his puckered tailhole. The boy went cross-eyed when he found his prostate. Shifting his focus away from his cock, his grinding against the pillow slowed and a second finger was quickly added.Top of Form
Coarse brown fur sprouted to cover his cheeks as his tail swished behind him. The changes were synchronized with how much precum leaked from his cock; the more he rubbed at his prostate, the more he leaked and the more he leaked, the faster the fur grew.
The changes began to spread to his fingers as the creeping corruption of donkey fur slowly enveloped the hand he was using to finger himself. It grew so rapidly it was as if it were being painted on with a brush. When the fur reached the fingers hanging idly, they visibly thickened. Judging by Tyler's groans and the way his eyes rolled in his head, the fingers inside of him must have been growing thicker too.
Tyler reached back with the other hand and began to feel at his fat rump. It squished under his grasp as he groped himself to help him to fall deeper into that bliss.
Suddenly, Roman shot up from his chair with teeth gritted and his hands tight around his cock. He stopped pumping and instead did all he could not to continue pleasuring his throbbing, edged cock. Wes tore his hands away from his prick as well and leaned forwards with anticipation. His eyes drifted to gaze at Roman's balls, which had grown even fatter. They swung beneath his towering manhood like cantaloupes.
The rest of him had continued transforming. Grey fur had enveloped his chest and added the slightest bit of muscle to his frame. It was just enough to put a tear right through the middle of the pecs on his t-shirt. Still doing all he could to avoid an orgasm, Roman unthinkingly hooked a hand through the rip and tore it with ease to reveal his body beneath.
He tossed the scrap of fabric aside and pulled what was left of it from his form. The fur had overtaken his shoulders as well as his neck and was now beginning to extend around to his back. His hands were untouched, but it wouldn't be long before it crept down from his biceps to alter them too.
The same could not be said about his feet as they had completely shifted into the hooves of a donkey. The fur at his ankles and the patches of fur on his hips now reached for one another, extending over the middle of his legs whilst slowly spreading out to wrap around.
Exhaling, Roman let his hands drop from his body. He spent a few moments panting and then began to breathe through his nose as the orgasm faded. He might have been able to go without cumming had Tyler not caught his attention.
The other half-donkey let out a deep, moaned bray causing both Wes and Roman's gaze to snap over to him. Roman froze, Wes tongue lolled with lust and the oblivious Tyler slipped a fourth finger into his needy, greedy hole.
Constant pleasure had fuelled Tyler's transformation to the point that he was even further gone that Roman. Lost in a daze, his eyes and ears twitched in synch and his buck teeth began to come in. He now possessed a donkey's head. A tuft of unkempt, blonde hair was the only thing left to mark him as Tyler.
The lower half of him had completed its transformation. His jeans were now ripped all along the legs and crotch. Fat, black balls had escaped through a large tear whilst his cock had been left trapped inside leaving a large impression on what little fabric was still clinging to his thighs. He must not have been wearing underwear.
Despite the haste of the transformation inflicted upon his lower body, his upper body was still relatively human leaving him looking somewhat like a satyr. All he had on his chest was a thin strip of brown fur going from his fuzzy crotch up to between his pecs. Nevertheless, his plump rump had translated into thick thighs which were more than enough to distract from the rest of him. At the very least, they had certainly caught Roman's attention.
Eyes transfixed on his friend's ass as it jiggled from the self-inflicted buttfucking, Roman's face scrunched up with desperate lust as his hands returned to his cock. On the stairs, Wes fumbled to grab a hold of his own dick as he began to furiously beat it to the sight of Roman's surrender.
It didn't take much for either of them to climax. Running both hands up and down his length, Roman used the palms of his hands and his curled fingers to pleasure every last inch of his prick. Wes had his gripped tight in just one hand, deriving an incredible feeling from the way his foreskin moved.
In the last moments their bodies tingled with electricity and the aching in their cocks became too much to handle. Slamming their hips forwards and tightening their grips, both pumped their cocks and shut their eyes tight as their orgasms surged forwards with one last potent throb.
Wes covered his mouth with one hand and moaned as he let out one shot of cum that splattered down onto the floorboards below. The rest dribbled down over his hand, dripping down onto the carpeted stairs as he prayed that his housemates had not heard him.
Fortunately, Roman was loud enough to cover for him. The man let out a bestial groan as he sprayed his spunk across the room. One rope went wide, finding purchase on Tyler's body whose head shot up to see where it had come from. He went wide eyed, surprised and attracted, at the sight of a transforming donkey in the place of his friend.
Roman's cock continued to erupt with wave after wave of seed. Nothing in front of him was spared. It hit the couch, the floorboards, the wall opposite him, the ceiling and even the light fixture! Each dropped he spilled served to complete his transformation.
Before the orgasm could even begin to slow, fur sprouted all across his body like grass growing in fast motion. There was not a single bit of human skin left in sight by the fourth cum shot, and by the six his face had shifted entirely into that of a donkey's. His ass had not fattened like Tyler's, but his body seemed to glow with power.
After the sixth, the transformation began slow. He was still able to fire off shots, but now some of it began to leak down over his length and hands. By the time Roman was finished, he was shaking and panting but was not nearly satisfied.
Roman's gaze slowly lifted from the floor. This time when his eyes fell on Tyler he did not freeze. His eyes fluttered, his cock began to harden again and his heart beat fast in his chest once more.
Wes did not wait to see what was about unfold. He wanted to, he desperately wanted to, but he also knew that he just had to order more of the beer. As he skittered off up the stairs, he heard the sounds of squelching lube followed by a loud, whined moan from Tyler. Even from upstairs the couch's squeaks and the powerful slaps of Roman's hips against his mates' ass could be heard. Wes pictured that fat, slab of horse meat thrusting in and out of a jiggling, fat ass.
His cock aching for more, Wes pulled a box from under his bed whilst he waited for his computer to turn on. From it, he retrieved a dildo in the shape of a horse cock and a large bottle of lube.
Moments later, he was pushing the thick, blunt head of that toy into his ass as he softly moaned Roman's name. He could hear Tyler doing the same downstairs, only he was practically screaming it on every other thrust. Jealousy and lust flared in Wes. He began to ride faster, pushing himself harder and little by little the toy began to slip deeper.
The store's web page loaded. With a trembling hand, he navigated through the shop selecting anything that caught his eye. Each strange and fantastical name had him imagining scenarios with Roman. He'd lost count of how many he'd added when he finally clicked on the basket, Hastily, he punched in his card details, the delivery information and hit complete.
Sudden howls of pleasure from downstairs caught his ear. He couldn't wait for the verification. Immediately, he hit tab and found one of the porn videos he'd left open; a video of a guy blowing his housemates monster cock under the bedsheets.
Just a few minutes later the medial ring slipped into Wes' asshole. He let out a sharp gasp as he began to streak cum across his carpet. Downstairs, the boys coated the couch with theirs and somewhere in an unmarked warehouse another satisfied customer's second order was starting to be packaged.
