Donkey!” Jeff praised Liam, the little boy’s dirty blonde hair getting a little bristlier while retaining its color and growing out wildly in a shaggy equine mane. Liam didn’t even budge to question it, his eyes lidded shut in bliss as his proto-muzzle gained a few more inches. His button nose fused with his lips as his nostril flared, growing moist and bulbous as his fattening equine lips allowed him to start easily shoveling more feed pellets from Jeff’s palm to his mouth. The last of his baby-teeth fell out in a matter of seconds as his now permanent bulky equine teeth began to mash the feed into a sweet slurry.
Liam’s broad donkey tongue seeped aloey horse drool onto Jeff’s palm as he polished off the last of those feed pellets. A guttural purr reverberated through his lengthening neck as Jeff’s hands gingerly jostled and tugged up the boy’s growing rabbit-like ears, feeling the membranous skin stretch like gum, lengthening and widening until his two new donkey ears stood perched on top of his head. Brown chestnut fuzz climbed up to the top as the rest of Liam’s face underwent a final change into the of a donkey’s. Bones snapped and muscles bulged, but the boy’s face displayed a peaceful demeanor, oblivious of his loss of humanity even as his head lengthened and broadened to fit that of a common donkey’s.
The changing boy’s hand rest of the top rung of the split rail fence as he opened his eyes again, trying to ask for another round of feed only to hear a screechy bray rasp through his throat. Liam froze, the realization dawning on him… his vision split to both sides… his T-shirt and shorts beginning to strain as they fruitlessly tried to hold in his growing equine girth...
“Hawww!” The boy screeched to his mother in a desperate attempt to ask for help, but the woman didn’t even pay him a glance of attention as she continued to fiddle with her phone.
Everything felt out of place to Liam… heavy and out of place. His shifting senses confused his slowly changing human mind as he registered nothing but the pungent, earthy scent of farm animal wafting through his nostril and over his tongue…
It was him… he was the farm animal… he was the donkey…
“You’re coming along just fine.” Jeff chuckled, the teen stepping over the fence, his hand running from the top of Liam’s head, down the side of his now muscular equine neck as if giving him a tour of his new body by petting and stroking every inch of it. As Jeff’s hand worked around the contours of Liam’s arms, bones lengthened and shortened, muscles bulging in the boy’s triceps to asinine proportions wherever that hand touched. Liam let out a bestial groan as that hand rested on his own, the boy’s metacarpals twisting and expanding as his middle fingernail exploded with onyx-black keratin, forever entombing his hand in a heavy, useless donkey hoof.
Adrenaline sped through Liam’s veins, prey instincts readying him to dart away from Jeff, but suddenly…
Liam howled out a surprised bray as he felt something big and warm bump against the bottom of his shorts, prodding right between his butt cheeks. It was the jack from before, the one he wanted attention from! The huge creature huffed, a fat drooly tongue panting humid mist onto the strained fabric as Liam felt the sheer heat of the stud behind, assaulting his new snout of the savory scent of equine lust.
It felt like a sauna. Masculine heat from the stud washing over every inch of his roiling body, urging more of that chestnut-brown sleek donkey hide to bury his pale human skin, shifting it his flesh to plump, lush animal hide as the changes spread down his midsection. The changing boy’s T-shirt gave up the ghost with a loud “RIIIIIP”, splitting in two as the cotton-polyester drifted to the ground, quickly getting lost in the dirt.
“Doesn’t that feel much better now?” Jeff chucked, watching the huge donkey jack that Liam took an interest in before start to take interest in Liam. Jeff’s hand glid across the underside of the changing boy’s belly, feeling his innards shift, pushing out his stomach into an equine potbelly, more fur engulfing it as the flesh grew thick and taut.
“Heeeheehe!” Liam whinnied, his body trembling and bucking back as he contended with all those tortuously delicious sensations pampering his new equine body. Images of his childhood flickered and flashed away, making him all too aware of his dwindling humanity… his family… friends… future… all of it dissipating into a haze in his mind as it began to clear all those memories away, making room for simple bestial pleasures. Liam drooled at Jeff’s touch, that hand feeling up every inch of new equine anatomy – teasing him about what he had become and how wonderful it felt just to be pet - how wonderful it felt to be a simple animal.
Those bulging shorts still clung to his rear reached their limit, the canvas fabric tearing to shreds as a nascent tail audibly popped from his rear. Muscular flanks covered in a thick layer of soft donkey fat wobbled out, revealing that nothing human had survived the changes – that chestnut fur sweeping over his rear, dusting his entire body in donkey hide.
Liam arched his neck back and brayed in pure bliss. The bigger jack’s tongue had dipped into the crevice under his tail hole, those fat, rubbery equine lips squelching against his still peach-colored starfish, kneading against that sensitive skin until is started to swell up. Those bestial lips slurped against Liam’s pristine boy ring as the flesh grew darker, the changing boy’s anus becoming an ebony black as the rim grew bulbous and squishy. The growing donut slopped back against those lips as the bigger jack’s tongue advanced to a sloppy French Kiss with Liam’s ring, the appendage wetly slurping inside as his anus bulged out to the size of Jeff’s fist, the hole yawning wider, almost swallowing the jack’s muzzle as he drank the mouth-watering donkey musk from Liam’s insides.
Jeff chuckled as he watched lewd courtship go on, the jack’s sheath growing chubby and fat as his bestial foreskin began to spit out that black spire of donkey meat. Two feet of black, drooling-wet, precum-drench stallion sausage, slapped against the larger jack’s belly. The adrenaline seeping through Liam’s veins turned into ecstasy, the new head of livestock enamored with himself as he and his partner prepare to consecrate his hew form. Liam was now entirely donkey… save for one last thing.
Jeff knelt down, peering between Liam’s hindlegs as he saw the last of the boy’s humanity hanging limply, rocking back and forth as the donkey body it’s attached to presses back into the huge jack behind it. Jeff pat Liam on the side before his hand gingerly wrapped around that four-inch-long boy cock, slowly beginning to pump it.
“Easy there,” Jeffs whispered reassuringly, “Let’s give your little noodle one last hurrah.”
Liam didn’t protest in the slightest – instead relishing the sudden touch to his most precious of places. That was what he was for now – just an animal in a petting zoo, eager to let anyone touch him wherever they wanted too.
The bigger jack’s tongue lewdly slurped out of Liam’s anus, that jet black donkey donut shimmered with a thick layer of mucous-like drool, his tail hole feeling empty now that the other donkey had retreated his snout from it. At least, until…
Liam’s eyes almost bulged out of his skull as six hundred pounds of donkey fell on his rear, the changed-boy’s body straining to hold the weight as the other jack grasped his belly in his forehooves, his massive spongey cock head ramming into Liam’s wobbly butt as it peppered the former-boy’s rear in sticky dollops of viscous equine pre.
A powerful bite nipped the new donkey’s mane as the bigger jack managed to finally strike gold, his flared cocktip lewdly smooching against Liam’s donut. His tail hole yawned open wider and wider, eventually swallowing that monstrous tip whole, eliciting a victorious bray from the both of them, the larger donkey pounding his member in using a whole horsepower to deliver a flurry of wet, wanton thrusts into the former boy’s ass.
Liam came right there – his tiny penis spurting out almost all his semen into Jeff’s hand, leaving nothing but a thin trickle of cum dripping from his cocktip. The little human member was swallowed up suddenly as it became entombed in a fleshy prison of developing donkey sheath. The skin attached to Liam’s low-hanging belly as the donkey’s tiny human organ became trapped inside as if it were some sort of cocoon, the tiny bulge it made as it rested snug inside grew bigger, signaling that it was about to change too.
Liam’s tiny testicles jostled, slapping against his groin with each lust-filled ram to his rear. The jack’s precum began to seep down from his stuffed anus, between his legs and down to his sack – the fluid dripping down his shivering balls as they too grew heavy, leather overtaking that last bit of human flesh as the boy’s family jewels expanded into foal factories the size of grapefruits – his black scrotum beginning to lewdly rub against his legs as the jack above him forced them to expand larger and larger with animal seed.
Soon the pair were in a world of their own – two animals fucking with all the subtlety of a blaring foghorn as the other patrons watched from a distance. Liam’s rear nuzzled into the other donkey’s groin like a perfectly fitting puzzle piece with each thrust, slopping wet slaps filling the enclosure as more animal pre mixed with Liam’s anal juices seeped down his powerful haunches. Even Liam’s mother was watching the two now, but her son had lost all concern for her – all shame. He didn’t know who she was now, all he knew was that he was an animal- livestock meant for a life of carnal bliss with his new mate.
Liam’s penis grew chubby and stiff before it too began to flop out of its sheath, but now – it was distinctly inhuman. The balmy, wet insides of his sheath had urged it to become as pitch black as his anus. A bulbous head followed by a long shaft complete with a fat medial ring slithered out of his sheath – a sheen of his old human cum still oozing off the now bulbous, fat equine glans. That was all that was left of Liam the boy now, just a glaze of boy seed, stubbornly clinging to that bestial cock as it slowly dwindled, dripping away onto the dirt as that huge cock swayed with each thrust from the jack on top of him.
The jack’s basketball sized testicles battered Liam’s as the bigger donkey hilted inside his rear, the two taut scrotums spanking one another as the former-boy’s prostate was swollen from all rough fucking. Liam spat out hot, breathy “Haw’s” as the jack on top of him hammered him with another flurry of bucks, until that two-foot-long black stallion sausage finally plumped up to its full size. A firehose of molten hot seed seeped into Liam’s stretched out insides, bathing every wall in steaming hot semen. Liam’s balls clenched against the other jack’s the first dollop of stallion seed spurting from his dilated cock hose until a deluge of it poured out onto the soil below.
A chorus of wet slapping and lewd brays rang out for a whole minute as the two lovers rode out their orgasm, Liam the boy was officially no more. Jeff checked the app – any suggestion that he was ever human was erased, leaving nothing but a big, endlessly horny donkey stallion in his place.
The bigger donkey dismounted, making Liam’s rear gush out off-white and eye-wateringly acrid stallion semen into a puddle between his shivering hindlegs. Jeff slapped Liam on the rear as the new donkey followed his partner deeper into the enclosure, cum still streaming down his scrotum as his ropey tail flagged high in the air – showing off his glazed donkey donut to all the patrons.
As Jeff turned to leave, a few children followed behind Liam, leaving Jeff to wonder whether he was finished here – whether a few more members belonged in the herd.
