Equine Ecstasy

By The Nome King, for Ben300 & Wyraachur @ Furaffinity
------------------------------------

The day was young and the sun hung high in the sky, its warming heat pulsating down on the fields of sunny England. The grass was thick and green and the corn was growing tall and thick, the farmers keeping their cattle out in the field to graze. Peter walked along the dirt path, carrying a supermarket carrier bag that seemed to be filled with various objects. His trainers trudged though the semi-moist soil and enjoyed the feeling of the warm wind beating against his face while the sun radiated light down upon the beautiful rural countryside of southern England. He thanked the heavens that he lived in such a beautiful place, and to see all the animals and wildlife directly in front of him instead of a TV was a nice change. Peter’s trainers pushed into the soil and left a Mark of his sole, the grass and leaves breaking beneath his step. His denim jeans were a little muddy at the bottom, small bits of dirt coating the frayed ends. A couple of strands of grass and hay stuck to his plain black buttoned shirt as he strolled though the country. Peter finally came to a public footpath gate, and scratched the back of his short black hair covered head before walking towards the wooden gate and pushing it open, leading out into yet another corn field.

Peter had just been talking over the phone to his friend and hopefully partner Ben, they were both meeting in a field for something to eat. Ben was adamant about a relationship but indulged Peter's requests every now and then, and he didn’t mind getting a little free food out of it either. Peter’s foot slid down a small dip in the ground and snapped him out of his daydream momentary, thinking about what he was going to talk about with Ben. He pulled his foot out the small dent in the soil, before carrying on down the dirt path towards the next gate, another large field filled with corn. As he walked Peter pulled his arm up and looked at his watch, and saw he was about 30 minutes early, a habit which often punished him to waiting. He was always very early to everything and never liked to be late, it gave him time to think. He smiled when he realised he would have to set out the food; ergo his early arrival would be overall beneficial to his situation. He wondered about the safety of his car and whether or not it would be a wise idea to leave it by the side of the road, but he thought it would be fine since he would only be with Ben for an hour or so. He had hoped to at least eat something with him, and maybe even reveal his feelings, but had no success thus far.

Peter continued to walk through the fields and came to the last public footpath gate, it was rusty and beaten and seemed to have a certain charm to it. It was one of the old kissing gates that seemed to litter the English countryside, and was more prominent on public footpaths than anywhere else. He pushed open the kissing gate and sniggered at the thought of its implications, wandering into the field he was going to meet Ben. He got a small shock when he saw three large horses standing and grazing in the field, their ears immediately pricking up at the noise of the loud “bang” as the kissing gate slammed back onto itself. He looked and saw two paint horses, and one large draft stallion grazing in the field, their eyes looking at him. 

“Huh, not so bad, they won’t bother us” he smirked, moving to his right in order to try and find a nice spot to set up the food. As he pulled out the blanket and unfolded it he was reminded of the picnics his family used to have in the fields around his very location, fields that would often be rich with grass and animals. He layed down the blanket until it covered the grass neatly, completlyforgetting about the horses that were staring at him with an almost obsessive curiosity. He had the blanket layed out near one of the long hedges that edged around the field almost like a wall, not too far away from the kissing gate. Peter kneeled down facing the hedge and reached into the carrier bag, rustling around to try and find the sandwich box. He found and pulled out the box, smiling as he unclipped the plastic clasp and opened the box up, pulling out the chicken and salami sandwiches inside. 

“Woahh, hey what the hell!” Peter shouted loudly, feeling edge of something poke against his naked skin around his back. He felt a warm puff of air brush across his skin as his shirt was stretched back across his shoulders since he had kneeled down. He turned around to see one of the large paint horses sniffing his backside, the other two close-by and watching intently.

“Go away, your not getting any of my food” Peter snapped, putting his hand on the horse’s nose and pushing forward against the equine intruder. The paint horse stepped back a bit before puffing loudly through his large flared nostrils in irritation, watching Peter as he turned back to the sandwiches, leaning his arm into the carrier back to pick out some juice. Peter heard a rustling moments later as the same horse began to sniff and poke his nose into the plastic bag having smelled a fresh apple, his nose sniffing the fresh fruit. He almost managed to wrap his big black lips round the flesh of the fruit before Peter leaned over and pulled the horses head back and slapped the paint horse lightly on the nose.

“No.....not for you” he snapped again, the paint horse shaking his head and snorting loudly in displeasure. If there anything you didn’t deny a horse, it was potential fruit; and the paint horse quickly became irritable as Peter removed the apple from the bag. Peter nearly had a heart attack when he felt a warm wet feeling around his skin, a loud snorting from behind him as he felt the horses tongue lick his back and upper buttocks.

“Woahhh hey what the hell” Peter snapped out loudly, standing up quickly as the horse withdrew his nose and tongue from Peter’s back, moving back a little as Peter stood up sharply. Peter gave the horse a strange look as It clopped back and moved his head to the side, his large brown equine eyes staring into Peter’s own blue iris's. Peter didn’t say a word, merely reaching his hand back and feeling the wet spot that now felt cold with the breeze. The large paint horse slowly edged towards him, his hooves digging into the dirt as he arched his large neck forward, his face virtually an inch away from Peter's own. Peter gently moved forward and reached out to touch the gentle giant, his hands rubbing across his large flat cheeks and down his thick muscular neck. 

“Your just a big softie aren’t you” giggled Peter, rubbing the horses coat and head gently, hearing him breathe slowly. The large paint horse reared his head up and sniffed his chest, nuzzling him gently. Peter felt a little guilty that he had gotten angry to the horse when all he wanted was a little food, and he didn’t seem bothered or angry either which seemed unlike a horse. Peter smiled as the paint horse moved his head closer nuzzling his chest and allowing Peter to wrap his arms round his neck, pulling him closely. Peter was taken back by how loving and almost intimate the horse was being, as if he was trying to apologise for trying to steal the food. Peter began to feel a warm sensation around the place where the large paint stallion licked him, his back beginning to feel almost hot. He found it strange since it still felt a little wet, but simply closed his eyes and enjoyed the feeling of hugging the warm stallion. Unknown to Peter; the skin around his back began to darken, slowly deepening in colour as the melanin pigment levels increased in his skin, changing it from a peachy pink, to a deep brown, then to a matt black. He smiled as he felt warmth pulsating around his lower back, seemingly spreading down between his buttocks. The paint horse turned his head a bit a managed to see his skin changing colour, poking between his red shirt and the demin jeans. He felt the warming heat spread down his backside and between his buttocks, groaning a little as he felt his ass tingle. He smiled and gasped as he felt tingling around his buttocks, the head spreading round his backside.  The point where the paint horse had licked had begun to tingle too, an almost tickling sensation making itself present as his skin pores reconfigured, changing into follicle cells. 

“Mmmmm your a good horsy aren’t you” Peter said, groaning a little as he felt the tingling spread from his lower back down between his buttocks. Tiny black hairs began to push out his matt black skin, his lower back starting to become the anchor for new soft black hair. The hair was soft however, and it grew thin and straight, the skin follicles changing and shifting as the hair stopped growing at a certain length. Peter started to feel light headed, almost dizzy as the tingling growth of black hair began to progress down between his buttocks and underneath the confines of his demin jeans. The hair started to grow like wildfire, spreading over only the discolouring skin, the hair round his buttocks and ass crack growing thicker. As the hair grew longer it started to itch his buttocks, prompting him to move a hand down to scratch, his hand however meeting his much fuzzier back. His eyes shot open as he felt the soft hair over his lower back, then gasping and reaching down; found more of it growing between his well formed buttocks. 

“wha...what’s.....is that....fur?” he gasped, rubbing the soft black hair and realising it to be a coat of fur, which was short and shiny, but very soft and warm to the touch. The paint horse nickered loudly in agreement, then leaned down and began to sniff his crotch, nuzzling it gently with his nose.

“Noo..dont...ohhhh....don’t do that......that....feels nice” Peter groaned, trying to retain control of his senses but as soon as he felt the warm nose of the paint horse rub against his crotch, he immediately felt a wave of powerful lust wash across him. A bulge began to form in his pants, causing him to moan and groan as the paint horse nuzzled his balls and swelling cock. His hand moved down his backside and he felt more fur down between his backside, then shocked to feel it growing beneath his fingers as he rubbed his buttocks. The large horse rubbed his nose against Peter’s crotch and made him grunt in pleasure, a surge of power pulsing through his loins and body. Peter bucked in pleasure as he pushed his hips forward, feeling a strange moving in his backside, an almost alien sensation in his rump. 

“Ahhh...ohhh god yes!” Peter moaned loudly, feeling his tailbone moving upwards inside him, a small nub pushing out just at the start of his butt crack, slowly gaining definition. He smiled and rubbed the horses head gently, feeling the strange nub moving and squirming about strangely. He didn’t know if what he was feeling was real, but as the nub started to grow out and gain definition; he knew he certainly liked how it felt. The horse nickered and nuzzled his chest, Peter's strange growth gaining a surprising length and an even more surprising rate. He groaned and smiled as he felt his vertebrae cracking loudly, the bone expanding and splitting into separate sections. The warm breeze gusted against his body, and Peter felt the wind brush against his new appendage. He was surprised to feel the wind against his matt black skin, the tail cracking and twisting further out. As he felt the strange growth move about, he felt it brush against his jeans, feeling through the tip. He arched his head up and closed his eyes in pleasure, his brain learning new neural patterns and another limb, his mind able to finally understand the feelings of his new appendage. Peter groaned as he felt new muscles twitch and move in his long growth, moving around and allowing him to twist the strange growth from side to side, even up and down. 

“A....a tail?.....whaaaa...ohhhhhh” he groaned loudly as he felt his new tail stretch and move around to his command, opening his eyes and looking into the horses own, loving the feeling of his tail moving around at his ass. Peter smiled and gasped loudly as he felt his tail reach full length, hanging between his legs and it was long enough to hand below his knees. He gasped as he felt strange tingling sensations emanating from the dock of his tail, which seemed like pins and needles rather than the tickling of his fur growth. After a couple of seconds the pain became rather irritating and Peter started to flick his tail from side to side, almost trying to “shake off” the pain. As his tail swished from side to side, thick strands of coarse shiny black hair began to grow, the fur around his back spreading slowly upwards across his spine. The tingling reached the tip of his new tail and finally that too started to sprout hairs, the flowing lengths of coarse hair bunching up into a flowing tail. Peter moved his hands back and felt the dock of his new tail, then brushed his hands across his long flowing hair covered tail, feeling the long strands though his fingers. He knew the feeling and the shape and appearance was undeniable, the tail was equine in nature, as was the fur and hair that sprouted from his body. Peter gasped and moaned, but didn’t feel shock, rather pleasure and sensuality. 

“Ohhh a horse....why.....do I feel....sooo sexy!” he moaned loudly, the last of the horse hair growing from his tail, allowing him to brush it from side to side, a big grin forming across Peter’s face. He wasn’t scared at all, it seemed so much like a dream he wanted more of the changes, he wanted to know what it felt like to have hooves. Peter grunted as he felt the paint horse nuzzle his crotch again, his pants starting to grow tight as his semi erect cock pressed against the fabric. Peter moaned as he felt his backside increase in mass, his tail flicking happily above his tight jeans. The paint horse nickered and watched as his hips began to widen, his Skelton becoming larger; the bone pressing against fabric. Finally his jeans couldn't take anymore, and the button that held them around his waist snapped off. The small button flew off and landed on the grass, the zipper quickly ripping down as he felt the jeans loosen round his expanding hips and backside. Peter moaned and flicked his equine tail, looking down to see the bulge growing in his pants, his rump expanding and pushing his jeans further down his legs.

Peter felt the fabric of his jeans move down his legs, the rough cloth scraping across his legs, leaving his boxers exposed and his legs naked. Peter smiled and kissed the horse’s forehead as he felt him nuzzle and explore Peter’s underwear, his cock pushing against the fabric of his boxers, making his apparent arousal visible for the stallion to see. The other two stallions were huffing and nickering as they saw Peter’s tail swishing happily from side to side his cock pushing against the fabric, the large paint horse that nuzzled him became a little frustrated and decided to take matters into his figurative hands. Peter yelped loudly as he felt the stallion’s teeth grip round his boxer fronts, the paint horse pulling sharply on his underwear and ripping them slightly. Another sharp tug made the tear down his pants even deeper which allowed his cock to show finally, the cold air bracing against his skin. The horse spied Peter's modest 6 inch shaft and smelled it, snorting through his nostrils and blowing hot musky air over the surface of his cock.

“Ohhhh....yes....that’s so nice” Peter grunted, looking down to see his foreskin folding back over his cock head and exposing his bright red human glans, his shaft at full erection as the large stallion explored it. Peter moaned and relaxed his tail as he felt the stallion use his rubbery prehensile lips to explore his cock head, very gently moving his hairy chin underneath his balls and tickling them every so carefully. The horse nickered and Peter bucked his head back in pleasure as he felt the stallion wrap his whole mouth round his raging hard erection, feeling his warm flat horse tongue rub up against his diamond cock. Peter loved how the paint horse’s rough tongue felt on his shaft; loved how his warm wet silky lips caressed and expertly rubbed his shaft. 

“God yes!!....ohhh don’t stop!” Peter groaned loudly, the pleasure making him grunt and groan while he enjoyed swishing his equine tail from side to side. The paint horse pulled his warm soft lips and textured tongue off Peter’s cock, then arching his large neck down to tend to his balls, a long tongue darting out and licking his ball sack. Peter grunted and moaned as he felt his small human balls being licked off by the big sexy stallion, rubbing hands across his head and neck in pleasure, as if holding a lover. Peter felt a familiar warmth permeating his skin, the hairs around his crotch squirming around and changing, making him giggle as they tickled his skin. He looked down past the horse’s large head and saw the skin around his crotch darkening before his eyes, higher concentrations of melanin seeping into the pores and changing it from his normal light skin colour to a dark brown, then an animalistic matt black. His pubic hairs had shortened out and had begun to stand on end, leaving him with a fine furry crotch, the skin discolouring round his cock, seemingly spreading like wildfire. He moved a hand down and ran his fingers through his fur, groaning as he felt his fingers touch the tip of his rock hard erection.

“ohhh that feels....don’t.....ahhhhARHHHHHH!!!” shouted Peter, a powerful surge of orgasmic lust pulsating through him as the skin around his cock began to darken and change, his hips bulking up and tearing the split boxers asunder completely. He felt his boxers fall off his legs and heard them fall to the floor, his cock starting to throb with a powerful pulsating pleasure, his prostate working overtime as precum spurted and leaked from the tip, the horse who was licking his ball sack moved his lips up to attend to the new snack. Peter grunted as he felt the familiar rough tongue rubbing across the back of his cock, making more precum spurt from his prick tip. Peter gasped as he felt his cock push upwards, almost as if something in his body was pushing more blood into his shaft. Looking down he smiled and groaned as his cockhead began to change shape, his whole cock nearly a wonderful matt black, his cockhead pulsating as he felt it reshape. The horse kept on licking his discolouring human cock, the head flaring out and pushing up, tiny bumps forming around the edge of his cock head. The paint horse licked the newly forming shaft, making Peter gasp as he felt his pisshole widening and bulking up, a strange shape forming round his urethral opening as it pushed out and became more defined from his cock head. At this point his cock head looked like a cylinder, his glans had formed up to form a round flare that had tiny bumps around the edge. The top of the head was rounded and his urethra pushed out the top; facing towards him in a strange short tube like shape. Even Peter knew this shape all too well, he knew this to be an equine cock, as he could see the other stallions long large shafts hanging loosely from their sheaths.

“Ohhhh god yes...make me a horse!” he cried out as he felt his cock move closer to his crotch, gasping loudly as he felt the skin of his cock press against the skin of his crotch. The two matt black surfaces sticking and bonding together, the black animalistic skin merging and pulling his cock tight close to his crotch. The only way Peter could describe the feeling; was having his cock super-glued to his crotch. However he looked down to see his cock shaft had formed into a matt black horse sheath, his human head still poking out the top. The sticking sensation went away and the paint horse moved back over to lick his much larger cock head. Peter smiled and felt the rough tongue get back to work on his equine shaped cockhead, licking it and causing his cock and sheath to thicken up, more blood pouring into his groin as he felt liquid fire coursing through his veins. Peter grunted and groaned as he felt the skin detach from his cock and sheath, his cock pushing out of his animalistic prepuce and leaking precum. His cock grew longer and longer, the skin changing colour in some areas, but staying pink in others. He watched as his cock grew from a long 8 inches, past 10 inches, until it stood at least 12 inches long, his shaft thickening around and under his new equine cock head, a median ring forming halfway between his head and sheath. Peter gasped as he saw his new stallion prick jutting from his fuzzy horse sheath, the paint horse nuzzling his ball sack.

“Ohhh....ahhhhh god….yes!...more!! Please more!!!” Peter shouted, his hands rubbing across his large thick horse dick, precum dribbling from the tip, Looking down he felt the tip of his cock resting against his chest, throbbing and leaking precum onto his hairy pecks. It was then he felt his ball-sack sink away from his body, churning up and down as the large paint horse nuzzled them gently, licking them occasionally, the skin turning darker and eventually a matt black. Peter rubbed his fingers over his large stallion prick while his scrotum changed colouration, the skin round his testicles a deep matt black. Peter flicked his hairy horse tail from side to side as he rubbed his thick horse prick, loving the smell of his large equine member. He shuddered as he felt his ball-sack fall even lower, his scrotum becoming more stretched and elastic as his balls Squirmed around inside his sack. He smiled and moaned as he felt the sexy paint horse licking his enlarging horse balls, the skin matt black which seeped down and stained his backside and inner legs like spilled paint. He was intoxicated with his own stallion musk and could see the tip of his large equine prick staring at his face, begging to be serviced. Peter wasted no time and wrapped his hands round his thick stallion member, rubbing it smoothly and groaning as he plunged his mouth round his flared equine head. He grunted and moaned as he took more of his long stallion shaft into his mouth, teasing his large pisshole and flared horse cock with his slippery human tongue. 

A loud crack was heard from Peter’s hips as the bones realigned, snapping into place. But the lucky soul was too busy giving himself an improvised blowjob, his hand rubbing his thick veiny marbled horseback passionate, while his tongue and mouth worked the tip expertly. It was pure bliss and Peter was lost in the sensations, loving the feeling of the wind bracing against his hairy horse tail, the warm puffs of breath from the nostrils of the paint horse who licked his large stallion balls. Peter grunted as the warming pleasure spread down his legs slowly, the skin gradually changing colour to the deep black of his sheath and ball-sack. Peter sucked harder and faster on his large stallion prick, groaning as he felt the onset of his first semi-equine orgasm approach, his massive cricket ball sized testicles feeling heavy as they churned and grew even bigger. Finally he felt his balls pull close to his body, a pulsating orgasm growing in his loins. Peter grunted and seized his muscles up, his much larger and wider hips bucked forward as he felt himself orgasm, cum rushing up his cock.

"Mmphhhhh ahhhh!!" Peter gasped loudly, his own stallion cum shooting into his mouth with a surprising force, causing him to lean his head back and gasp with a mouthful of cum as his stallion seed sprayed over his hair, nose, mouth and chin; the paint horse getting a good coat of cum too. He moaned and smiled as his prostate pounded him gently with a slow but powerful pulsating orgasm, his cock wet and sticky from his horse seed.

"Mmm ohhh it tastes so good" gulped Peter, licking his cum covered lips from his stallion cum. The paint horse reared back a little from the shot of cum that splattered over his face, matting his fur together. Peter reached a hand out and stroked the beautiful stallion’s mane, flicking his own horsy tail about in pleasure. Peter saw the paint horse’s cock was erect, hanging down from his sheath, the sheer weight of the massive shaft making it droop towards to floor. Peter licked his lips and craved to have more equine cum in his belly, loving the taste of his own. Peter’s still erect cock held close to his body as he kneeled down on the soft grass, moving underneath the large paint horse. He angled himself underneath the large beast, hearing his breathing and panting. Peter spotted the other two horses rubbing against each other, the larger bay draft stallion nickering loudly and moving behind the smaller paint horse that was similar to the one he was under. Peter smiled and began to rub his own horse cock when he saw the large draft horse mount the smaller paint stallion, his thick marbled cock pushing deep into the muscular matt black ass that seemed so like his own.

"Mmm ohhh it smells so good" Peter moaned, sniffing and rubbing the shaft of the big paint horse he kneeled under. He gasped as he felt the sane warming sensations make themselves present on the parts of his skin that he splattered with his horse cum. Unknown to him; his lips had begun to discolour, changing from a peachy pink, and the colour fading slowly from his skin as it changed to a dark matt grey. Peter flared his nostrils and felt them stretch a little, opening out wide as he smiled and puffed air quickly through them. He took a deep breath through his expanding nostrils, realising it to be much more effective than breathing through his mouth. He moaned as he felt his lips tremble, opening his mouth and puffing through his changing nostrils as he wrapped his thickening lips around the big stallion shaft, rubbing the veins and sheath lovingly. He felt Precum trickle down his throat, making him push his lips even further around the large shaft. He moaned with a mouthful of cock as he felt his nose and mouth twitch a little, his lips looking far more muscular and animalistic than before, his nostrils taking a familiar equine shape.

Peter heard the nickering paint horse behind his head, arching his head down and drooling from his thick horse lips as Peter sucked him off. Peter felt his ears twitch a little, and then it felt like somebody had attached two thick hooks onto to the tips and were pulling them up. He felt muscles around his head twinge as they moved over the bone, a slight aching pain as they enlarged and shifted, old vestigial muscles moving round to the base of his ears. Peter could feel his ears shifting up and knew what it meant; he knew what was happening but only kept on sucking the delicious horsecock. Moaning and slurping on the large flared phallus he realised that this was what he wanted, he wanted to become like his makeshift lover, wanted to become more equine. Warmth surged through his ears as they shifted and cracked, the cartilage moving and shifting to form a pointed tip, his lobe curling round. His skull shifted slightly and brought his ears up to near the top of his head, the skin starting to darken. Peter flicked his tail in delight as he felt the new muscles in his ears respond to his will, being able to move them up and down, then forward and back. Another nicker from the paint horse allowed Peter to test his new ears out, swivelling them round to direction of the noise behind him. He closed his eyes and moved his ears as they started to discolour, changing from a peachy pink, through brown and finally black. Peter flicked his equine ears in delight and took more of the horseback deeper into his maw, his prehensile lips wrapping round and delicately caressing the paint horse’s shaft. 

"Mphhh ommphhh" Peter groaned; trying to speak but lost in the pleasure of the sensations, his body overloading him with feelings. Tingling sensations started to move round his ears and head; Peter flicked his tail and smiled with a mouthful of horsecock as he knew what was happening. Thick black fur began to grow around his ears, covering them quite quickly and then slowly growing round the back of his head and neck.

Peter moved both hands away from the shaft and touched his new horse ears, feeling their soft furry surface and loving how nice it felt for them to be caressed and rubbed. He flicked his equine tail from side to side, loving the taste of the paint horses shaft, one hand rubbing and caressing his well shapen horse ears, the other rubbing his own horse dick lovingly. A nicker and a whinny was heard from the paint horse, Peter feeling the massive equine prick throbbing in his mouth and he knew that it was time for the stallion to cum. Peter moaned and rubbed his shaft quickly, the other hand moving up and rubbing the pain horses shaft quickly, pushing the head deep into his throat, ready to receive his delicious reward. The paint horse whinnied loudly and Peter’s eyes shot wide open as he felt a powerful spurt of horse cum shoot down his gullet, followed by yet another powerful pulse of horse cum. But Peter was having trouble swallowing it all and leaned his head back, folded his ears to the side and closed his eyes. He moaned as he felt the thick warm equine cum spurt over him, splattering on his shirt and hands, over his upper body and neck, his hair coated in thick stallion seed. His cock felt rock hard and it began to pulsate and throb as the drips of horse cum drizzled over the top of his cock head, making him shiver in pleasure. 

“Ohhhh yes!....sooo good” the slowly changing Peter moaned, his mind still in a haze of lust and passionate equine thoughts, thoughts of his own body changing completely into a large black stallion, the fantasy much closer than he realised. Thick cum drenched Peter’s hands and he moved them up to his mouth, licking the delicious sweet and salty cum from his skin, enjoying and savouring the taste. As he licked he saw his nose had turned a dark grey and smiled in the knowledge he was becoming something more than human, something magnificent and graceful. As he licked the cum from his fingers and hands he noticed his skin had become to change to a darker colouration, the discolouring spreading like some sort of strange skin infection. This was the first real change Peter got to properly observe and he held his hands out in front of his face to observe the changes. He heard a whinny from his left and saw the large draft stallion fucking the smaller paint horse, their animalistic sounds echoing thought he field. Peter’s skin changed from a pink to a deep dark brown, and then finally to a black, spreading across like somebody was staining his skin with dye. He smiled and felt the thick gloopy cum slowly absorbing into his skin, changing it and discolouring it; the fluids somehow fuelling the change. His fingers soon became discoloured and black, the colouration spreading up his arms and through his shirt sleeve, out of sight.

“ohhh yes....more...please...i want more” Peter gasped, his fingernails starting to bulk up and stretch out, his middle finger growing thicker and larger while his hand started to stretch. He was amazed to see his other fingers slowly receding back into his hand, the mass of his previous fingers all pushing into his new deforming middle finger, the nail growing huge around the tip. His hand grew longer and longer, the bones melding together into a solid mass, pushing out his finger away from his wrists. He felt his finger drop down with the weight of the growing nail, only to find he could only bend his finger back and forward, only bending at one point instead of three. He knew what his hands were becoming, and he welcomed it as his hands extended, small dark patches of shiny black fur beginning to grow around his arms, spreading down slowly toward his deformed fingers. His nail curved round and Peter smiled and moaned as his fingertip stretched underneath and behind the nail, the bone growing thicker until his middle finger, hand and lower arm all looked like a single unified equine limb. The nail curved down and began to thicken, the shape now unmistakable, his new arms getting a nice covering of his beautiful black fur. The fur grew down his arms, approaching his new reshaping nails, now undeniably a pair of equine hooves, the ends smoothing out as he felt the weight of the keratin pulling his newly configured front legs forward. Peter smiled as he felt the fur grow down and round his legs and new horse hooves, making his hands and arms nothing more than a pair of equine forelegs.

“Ohhh my....hooves....so....heavy” Peter grunted, as he rubbed his forelegs over the thick horse erection that jutted out his matt black equine sheath, the fur growing up his arms as the skin discoloured round his shoulders. Peter gasped loudly as he felt his shoulders crack loudly, the bones reconfiguring and moving position, his chest becoming broader as his pecks shrank down and became rounder. As his shoulders and upper body expanded it caused his buttoned shirt to become tight on his discolouring skin, the fabric stretching and tearing in places. With a loud “pop” a button flew off his shirt, falling on the grass but was followed quickly by another. All the other buttons followed suit and began flying off one by one, his chest and shoulders tearing apart and ripping his shirt wide open. Peter groaned as he felt his hairy chest brace against the warm breeze, his ears swivelling over to hear the panting and puffing on the fucking stallions near him, the paint horse above him beginning to move back to face Peter. 

“Ohh...it feels so warm” he moaned quietly, feeling a strange heat pulsating in his upper body as his pecks changed shape, his arms and shoulders moving further to the side. While Peter still had the use of his elbows he moved both hooves round and lifted them up to his chest, feeling their hard surface against his hairy chest. He groaned and smiled as he rubbed his discolouring chest with his big dirty horse hooves, his skin changing colour around his shoulders and chest as fur covered his arms completely. The paint horse moved back and managed to angle his legs back over Peter who kneeled on the grass, caressing his chest with his large horse hooves, loving the feeling of having such equine attributes. Peter looked up and saw the pain horse standing over him, his mouth and lips above his head, puffing loudly through his nostrils, his erection still hanging strong. Peter saw the paint horse clop his hooves loudly in the dirt, moving round and exposing his ass to Peter. He watched as the paint horse swished its tail up and down, wafting his anal scent towards the changing human. Peter's nostrils immediately flared and sniffed in the glorious smell of the horse’s ass, his erection growing even stronger as he caught another whiff of the stallions powerful musk. He licked his big grey lips and imagined the thought of fucking this stallion, claiming him as his own. He felt his tail swish as he used his hooves to push himself up from the ground, realising that he had grow a lot larger since he had been kneeling down and sucking off the horse. He kicked away his loose jeans that lay on the floor, the button broken and useless, his shoes still on. He was at least 6 foot 5 now, from 6 foot 2 and had gained a little muscle mass, his arms quite bulky with strong powerful muscle. However his erection could not wait and his lusts took over when the stallion moved his tail to the side, exposing his firm matt black rump, the thick muscular asshole giving off powerful sexual odours.

“Ohhhh yesss......ahhhh you dirty little stallion!!” Peter smiled and spoke, grunting as he felt the tip of his large equine prick sink deep inside the stallion’s rear. His whole body shuddered with pleasure and power, his loins pulsating with powerful pleasure as more and more of his long thick veiny marbled horsecock sank into the tight black muscular ass of the paint horse. Peter began to thrust in and out of the horse’s ass, groaning as he felt every inch of his member press against the moist walls of his equine anus. A loud “Crack!” from his shoulders made Peter groan as he felt his arms snap into position, his upper human arms shortening in length, his upper and lower horse legs growing longer. His elbow and upper arm shrank and sank into his sides, while he felt his forward bending front horse legs grow longer as they rubbed down the sides of the paint horse he was fucking. He realised by now that his upper body was about the same size as the paint horse, a fact which made him even hornier and wanting more. It felt like having your elbows next to your nipples while your lower arm and hands hung down limply, but with every thrust from Peter’s large hips, he became more and more comfortable with his new posture.

“Ohhh yes...make me a stallion....I want to....OHHH!!!” Peter shouted and snorted, his nostrils flaring as he fucked the paint horse wildly, his upper arms now totally equine his chest and upper torso nearly completely covered in fur. Peter gasped loudly as he heard a loud “SNAP!” from his spine as it reconfigured and shifted, now permanently moved to a quadrupedal stance, meaning Peter was never able to walk on his two feet again. But he didn’t care about that, he only wanted more of the change, wanted to become more of the sexy black stallion, the fur completely covered his upper body now, and spread down his back to meet the black fur that already coated his ass. Peter smiled and giggled as he felt his ass bloat out and stretch, his ass-cheeks growing bigger but pulling them apart. His buttocks now seemed to rest partially on the sides of his hips, leaving his sexy black asshole exposed and his large equine ball-sack to churn up and down freely. The change seemed to be progressing faster now, it seemed that sex was the fuel and Peter was enjoying screwing his “makeshift mare”.

Another loud snap from Peter’s hips confirmed the progression of his transformation; his legs starting to discolour as his entire upper and lower body were coated in shiny black horse fur. Peter flicked his tail from left to right, swatting off some fly’s that he felt resting on his rump, his upper and lower body now slightly larger than the paint horse he was fucking, his body nowhere near human sized anymore. He heard a loud whinny from the stallion beneath him as his cock began to increase in size, his sheath bulking up and swelling. Peter moaned and smiled with glee as he felt his equine member growing longer and thicker within the confines of the stallions ass. Cracking and clicking was heard from the grunting humans ankles as his felt the warmth spread down to his toes, the black skin spreading across his legs and feet. He felt his feet begin to extend forwards, putting pressure on his trainers and his toes. 

“Gahhhh ohhh damn.....ahhhh!!” Peter grunted in pain, finally gasping as he felt the stitching give way to his growing feet, his toes splitting through the ends and extending outwards, allowing his hips to move upwards slightly. In this posture he was able to properly thrust his hips back and forth without angling his cock, finally he felt like a true stallion. Moaning as Peter thrust his long horse shaft deep into the stallion’s worn tail-hole, his middle toe began to expand on each foot, the other toes starting to shrink and sink into the flesh. Peter smiled and kept on thrusting his big equine hips in and out as he felt his toe push out, the nail curving round as his other toes disappeared into his stretching foot. His toe was about the same thickness as his thickening foot, a long tendon forming down under his once human sole, as the bones in his foot melded together. He felt his upper human legs sink slowly into his hips, while his lower human leg cracked and bent out behind his ass, forming a digitgrade pair of hind legs.

“More.....oh please god more!” Peter cried out in pleasure, his cock spurting precum into the stallion’s worn ass, an orgasm near and his lust reaching new heights. His nails curved round and dug deep into the soil, his toe bending only on one place like his new front legs did, now possessing a pair of fully functional rear horse legs. Peter grunted and dug his hooves deep into the soil, pushing his cock even deeper inside the paint horse, his flared stallion cock tip breaking past the second sphincter and into his rectum, making him whinny in delight. Peter groaned too, his own orgasm was so close, the sensations of his new equine body were intoxicating and he begged for more. But Peter was pulled out his trance when he felt the fur cover the last patches of his legs, his neck about to change. Peter heard a creaking from his left and moved one of his horse ears round to find the source of the nose, realising it to be the gatepost.


“What the HELL!” screamed a familiar voice from the corner, Peter’s heart stopping when he recognised it. Ben stood and watched Peter’s cock drive deep into the whinnying stallion’s backside, his neck thickening and changing while his head remained partially human.

“Peter....is that....oh my god!” shouted Ben, shocked to see his friend changing into a large stallion, his neck cracking and moving forward while a loud crack echoed from his nose and jaw.

“Ben.....please forgive me....I’m sorry....but it feels..sooo niiiceeeee Niieeecce NIEEEGHHHH!!!!!” Peter groaned and finally whinnied loudly, his neck and vocal cords shifting and changing. He whinnied and snorted loudly through his nostrils as he felt the powerful pulsating pleasure in his loins, an orgasm finally pounding through his fully equine hips and forcing him to jerk his cock deep into the paint horse’s ass, both stallions whinnying as pleasure surged through them both. Peter felt his face crack and push out as he whinnied and cummed, his nose and mouth forming into one unit, his face cracking and moving out in front of him. He felt his forehead increase in width which in turn forced his eyes to the side, making him open them wide as they changed in shape and size. Peter flicked his equine ears and tail while he felt his eyes move to the side of his expanding head, his front incisors and canines flattening out and becoming thick dirty slabs, his lips becoming thicker and prehensile, the grey skin spreading up his face from his big horse shaped nostrils. His hair began to grow longer, becoming coarser and lighter as Peter felt it grow down his still lengthening neck, cracking finally into place. He whinnied again as another powerful surge of cum shot into the stallion’s ass, his eyes becoming larger and darker, and the pupils changing from a round dot to a long rod shape. Peter shook his large head from side to side as his mane grew out the top of his neck, prickling sensations moving up from his neck and cheeks, down his face and covering his head. Peter let out one final loud whinny as the last bit of skin was changed and covered over with soft shiny black fur, leaving him changed into a large shining black Arabian stallion. 

“Oh dear god.....what the hell Peter.....this can be happening” Ben spoke, looking at his friend dismounting from the smaller paint horse, now as a shining example of a stallion. Peter moved his head from side to side and tried to get used to seeing through the side of his head, and spotted a human. He remembered Ben, he was a friend and that’s why he had come to the field, to see him.  

“Ok this isn’t real, what the hell” Ben shook and stammered, trying to comprehend what was going on. Peter felt himself overcome with urges, feeling of lust and power. He was a stallion now; a pathetic human couldn’t stand in his way. Slowly Peter clopped towards his human friend, his mind trying to fight back against his equine urges, but they were far too strong to resist. Ben backed off and felt his spine touch the hedge as Peter approached, finally meeting him and seeing Peter’s big equine nose sniff and nuzzle him gently. 

“Peter....are you still in there buddy?” Ben asked, reaching out a hand and rubbing his friends big horse forehead. Peter realised why the paint horse liked being petted so much, it really was soothing and somehow very sensual. Peter nickered and nuzzled in response to Ben's question, trying somehow to communicate with him.

“We'll fix this, don’t you worry” said Ben reassuringly, rubbing Peter’s head and neck, making him puff through his nostrils. Peter felt a little guilty being near Ben, he knew that he had become a stallion through the same actions he was performing to Ben, but yet he continued to lovingly nuzzle and rub against him. It would have been a lie if Peter didn’t want Ben to join him, he had gotten so much pleasure out of being a big horny stallion and he wanted to share it with Ben.

“Ohh Peter, don’t do that” Ben playfully giggled, feeling Peter’s long wet equine tongue licking his neck and chest through his T-shirt. Ben moaned as Peter’s rough wet tongue moved across his soft human skin, a permeating heat spreading across his neck and chest. Peter was having a hard time seeing his handiwork due to his new eye positioning but was able to look down his muzzle to see his nose and mouth. He worked his prehensile lips and suckled a little on Ben’s skin, spreading his slimy equine saliva over Ben’s neck.

”Ahhh...what’s gotten you so friendly” Ben moaned, the head pushing down into the pit of his stomach as the strange “trip” ensnared his mind, making him dizzy and light-headed. Like Peter before, Ben lost all sense of reality as his skin began to darken, the tone changing from a light peach down through browns to finally a matt black, the colouration spreading like infection. Ben groaned as he felt the heat pool in his hips and loins, spreading to his adrenal glands and prostate, his body working overtime to produce the hormones necessary to keep up with his change. Peter moved his head down to see Ben’s neck and shoulder changing colour on his left side, the discolouration spreading round the right hand side of his neck and shoulders. Peter did his best to smile with his thick horse lips, flicking his tail and ears as he observed the very same changes which took hold of his body; now a stunning Arabian stallion.

“Ohhh….god….I can see why you liked this Peter” moaned Ben, rubbing his neck and feeling his skin also changing texture too, instead of soft and smooth like his human skin, it was somehow finely textured, as if rubbing your fingers across fine silky sandpaper. Ben loved the feeling of his new skin and gasped when he could feel prickling sensations move across the 'Infected' areas, tiny hairs poking out the black skin and growing under his fingertips. Peter watched as a shiny orangey hair began to poke out his changing follicle cells, Peter knowing exactly what was happening. Peter nickered and watched in fascination as Ben's bay coloured fur started to spread round his shoulders and neck, the black skin spreading up the back of his neck and stopping just below his chin line. Ben groaned and rubbed his neck in pleasure, his cock wriggling in his pants as he became aroused by the feelings that afflicted his changing form. Ben arched his head forward as the fur grew round the back of his neck and an almost “pins-and-needles” sensation spread along a line down from his neck to the top of his back. He reached his hand round to try and scratch, but instead gasped when he felt thick long strands of coarse horse hair pushing out his follicles, the fur now completely covered his neck and upper torso. He smiled and allowed the growing mane to flow through his fingertips, loving the feeling of his changing neck and his glorious bay fur warming his neck and shoulders. He smiled as he felt the same “pins-and-needles” sensation flooding into his scalp, his hair begging to lengthen as it changed texture to become more coarse and changing from a brown to a deep black. He watched as the growing locks of hair pushed down his eyes, and he smiled as he used a hand to brush it behind his still human ear. 

Peter nickered and drooped his ears down as Ben groaned and began to pet and rub Peter’s large long face, running his fingers through his long mane and lovingly touching his neck and cheeks. Peter let his eyes droop down slowly as he relaxed, spotting the large draft horse moving next to Ben’s left side and began nuzzling and poking at his trousers and hips. Ben moved a hand round and petted the draft horse while his other hand rubbed Peter’s face lovingly, Ben moaning as he got attention from two horses. Peter began to nuzzle and use his lips to grab at Ben's trousers, sniffing and smelling Ben's cock inside his pants, wanting something to lick and change next. Ben moaned as he felt the draft horse sniff at his ass, his lips trying to pull off the fabric but with no avail. Peter finally had an idea and gripped the cloth with his teeth; the draft horse that sniffed his backside did the same. Ben was momentarily snapped out of his trance as his hips were pulled back and forth as both Peter and the draft stallion used their teeth and heads to rip and tear his trouser fabric. Ben's trousers were only simple cloth and tore easily, tearing apart the trouser legs and causing his zip to break and his button to unlatch from the waist hole. Ben looked down to see Peter tearing off the last shreds of his trouser legs, leaving his legs bare and naked for both sexy stallions to access, the only thing in their way was his underwear. Needless to say Ben didn’t allow them to tear off his pants, but instead willingly pulled them down his legs, exposing his semi erect cock, wanting the sexy horses to initiate the changes that he knew would afflict his genitalia. Peter nickered in agreement and smiled as he watched his friend pull down his pants, his wants and intentions made clear by his actions. 

His reaction was even more of an indication of his perverted thoughts as he groaned while the large draft horse began to sniff at his backside, Ben gasping as he felt his friends big grey equine lips exploring his privates. Using his rubbery prehensile horse mouth; Peter began to lick and suckle on Ben's erection, causing the groaning human to rub the gentle Arabian stallion's soft head, teasing his ears and mane as he received the most amazing blowjob from his equine friend. The draft horse behind him began licking his backside and lower back, nickering as he saw the darkening skin spread from the wet patches of skin left by his oral exploration. His crotch had begun to darken too, the skin discolouration spreading from his erect shaft and down round his crotch, making it clear that his cock was undergoing the same alterations. 

“Ohhh Peter....don’t stop.....please!” Ben moaned as he felt his cock pulsate and throb with liquid heat, his blood surging with testosterone, his cock thickening and expanding within Peter’s maw. The large black Arabian stallion recognised his friends increase in manhood, and responded by sucking harder and faster, enjoying seeing his friend in pleasure. Peter grunted as he felt a prodding twisting sensation at his backside, his coccyx stretching upwards and moulding the skin as the bone moved inside him. He gasped as a small nub grew through his discoloured matt black skin, fur beginning to form and spread across his backside. 

Ben moaned as he felt another breath next to his right ear, the other large paint horse sniffing the side of his head, Ben's long black mane hanging freely down as he felt the paint stallion's presence. He reached out an arm and rubbed the paint horses head lovingly as his backside was tended to by the draft horse, his sexy Arabian stallion friend sucking his changing cock off. Ben gasped as he rubbed his friend’s large equine ears while the paint horse got to work on his own, Ben feeling the stallion's big wet lips wrap around his own ears and licking the lobes with a rough, but caring and sloppy tongue. Ben felt a wriggling in his asshole, the draft horse moving his mouth and nose down between his ass-cheeks and sniffing his butt-hole, licking his buttocks lovingly, more of his skin changing. Ben gasped in pleasure as he felt his cock slowly sliding up Peter’s long maw, the glans pushing and rubbing against the roof of his long equine mouth. He grunted in pleasure as he felt his cock head reshaping the edge flaring up inside the warm wet environment, his shaft stretching further up his friend’s horse muzzle as it expanded in girth, Peter’s mouth stretching open was testament to Ben’s expanding width.

“Ohhhhh god...why does it feel so.....gooood!” Ben groaned, shivering in pleasure as he felt warmth around his cock and crotch, his backside and ass, even his ears as the paint horse licked them lovingly. His ears began to stretch and change, the tips forming small points while the black skin moved upwards past his coarse equine mane, new muscles aching in the side of his head as they stretched and moved. Ben smiled through his moans and constant heavy breathing as his ears moved upwards, the skin beginning to tingle as fur started to grow, his shining bay coat covering his ears and moving down to meet the fur on his neck. 

Ben was in heaven, his cock was expanding and being sucked off by his sexy stallion friend, his backside was rapidly shifting as he felt a cracking from his expanding nub while his ears were moving and shifting from the attention he was getting from the paint horse. Ben felt his knees and legs shiver and wobble in pleasure, almost unable to stand from the sexual lust he found himself under as the three makeshift equine lovers pleasured his body all at once. Ben smiled as he felt his nub gain length and girth, the vertebrae expanding and stretching out into a long fleshy tail, the skin on his tail and around his new tail dock was a deep matt black, the colouration spreading up his back and down between his wet ass cheeks; the draft stallion giving it a loving coating of equine saliva. Ben bucked his hips forward as the draft stallion pushed his long flat tongue between his ass-cheeks and licked his shivering ass hole, making it quiver as it too began to change. Ben felt his tail tip rub against the draft horses head, making him move it upwards to as to avoid poking his equine lover in the eye, realising he was growing a long semi-prehensile tail. The same “pins-and-needles” sensation hit the skin on his tail and around the point where his tail met his backside, coarse jet black fur starting to move out the changing follicle cells. Ben rubbed his mane and knew the hair round his tail was starting to grow, happy in the knowledge that he would have a tail like his friend's soon enough. 

“Ohhh yes...make me a stallion!” Ben groaned loudly, his balls aching as they began to sag and swell in size, his loins pulsating with orgasmic pleasure as he felt he was near to orgasm. He could feel his cock all the way inside his friend’s long equine mouth, stretching deep inside, further than he would ever have expected it to go. Ben felt the muscles in his tail twitch and move, making his tail flick from side to side, whipping the ears of the draft horse. Needless to say the large bay draft horse was displeased and moved himself backwards then forwards again to gain access to his testicles, allowing his tail to flow free. Ben gasped and smiled as he flicked his new horse tail from side to side, loving how it felt to have such a useful and sensual limb. 

“Ahh....OHHH GOD!!!!” Ben grunted and shouted, his cock shuddering and his balls churning as he felt the draft horse licking them lovingly, his friends long wet mouth causing his cock to shiver and pulse with pleasure. Ben grunted as he felt his ears cover with fur completely, new muscles allowing him to move and flick them, causing his pleasure to reach new untold heights. Peter grunted and flicked his tail and ears as he felt Ben’s long changed cock pulsate and throb in his mouth, his friend feeling his first equine orgasm. Ben groaned loudly and gritted his teeth as wave after wave of orgasmic pleasure pulsed through him, causing spurts of thick hot horse cum to spurt from his cock tip and into his friends waiting gullet. Peter snorted heavily through his nostrils as he drank the huge quantity of semen he was given from his friends changed equine shaft. Ben screamed and drooped his long horse ears down in pleasure as he felt his cock shudder in pleasure, thick horse seed spurting and giving Peter his meal. Ben flicked his tail and moaned as his orgasm died down, his erection still as strong as ever. Finally the last of Ben’s horse cum spurted out his thick prick and Peter began to pull his mouth off his now huge cock, Ben moaning as he felt Peter’s soft silky horse lips stretch and massage his erection as the big sexy stallion withdrew. Ben shuddered as Peter’s lips wrapped and finally popped off his much larger flare, finally looking down and getting a glimpse of his new longer shaft.

“Ohhh OHHH YES!” Ben gasped in delight, looking down at the huge horse cock he now sported, attached to his crotch by a strange looking sheath. His cock was thick and very long, veins covered his multicoloured shaft; the skin was marbled like Peter’s. He could see his cock was a light pink with black and brown splotches over the surface, his cock head was now a large bumpy equine flare, his urethra poked out the top of his cock via a short tube like structure. Cum oozed from his pisshole and dribbled down his long equine shaft, his cum drizzling over his big stallion balls and making them shiver and grow even bigger. Ben's large black horse balls hung down low from his thick equine sheath, swelling to the size of baseballs as cum dripped from the smooth edges. Peter nickered and nuzzled Peter’s cock, causing him to groan in pleasure. Ben smiled and groaned as he felt the draft horse invade his backside once again teasing his now matt black horse ass with his wet tongue, new thoughts running through his head. Peter was having similar thoughts, his mind on the large draft horse mounting the paint horse earlier, he wanted to fuck his friend, screw him into equine-hood.

“Ohhh Peter, I want you....do me......i want you inside me” Ben moaned as he flicked his ears and tail, kneeling down in front of Peter and rubbing his big furry grey horse chin. Ben pressed his lips against Peter’s big equine kisser and opened up, his tongue wrapping round Ben's short human licker. Peter realised this was their first kiss, and what better way to share it as a horse. Ben rubbed Peter’s head as they shared a passionate but messy human-on-horse kiss, Peter’s big sensitive prehensile lips feeling everything in intimate detail as he made out with his half human-half-horse lover. Ben departed from his loving snog and smiled as he saw a string of drool trail from his lips to Peter’s mouth, Ben knowing exactly what he wanted. Ben turned over on his knees and pressed his hands into the dirt like the animal he was, reaching out behind him and stretching open his asshole, groaning as he flicked and moved his horse tail to the side, exposing his muscular matt black asshole.

“Fuck me! Screw me like a mare!” screamed Ben as he presented himself to Peter, his mind in a haze of sexual lust, his long horse cock dripping cum into the ground. Peter nickered and approached the submitting human, now able to see a line of fur spreading down his back under his t-shirt towards his already furry backside, the skin colouration spreading to cover his entire ass. Ben panted as he saw Peter’s big hooves press next to him as he heard him breathe; Peter nickering as he slowly pushed his hips forward. Ben gasped and moaned in pleasure as he felt Peter’s thick wet equine erection probe his asshole invasively, finally stretching him open with ease and making Ben yelp in pleasure as his flared stallion shaft “popped” inside his asshole. The changing human moaned in lust as he felt every inch of his friends stallion shaft stretch him open, feeling every vein rubbing against his sensitive horse anus. Ben's hips cracked loudly as he felt the tip of Peter’s cock press against his second sphincter, making his ass stretch out, his buttchecks spreading to the side slightly and allowing Peter full access. Ben moaned as Peter withdrew his cock a little, more fur spreading down and around his bloating ass. Another loud crack sounded in his legs as he felt his feet press against the dirt and push his upper body up, pulling his ass into the air as his friend moved his cock inside him once again. 

“Ohhh Peter...don’t stop....make me yours!” Ben gasped, his ass up in the air as he watched his hands start to snap and crack involuntarily. The two other horses watched with fascination and intent while the human was lovingly screwed into equine hood, his ass and backside expanding with flesh. Peter whinnied as he thrust his cock inside again, hearing the snapping and shifting bones of his lover underneath him. Ben smiled as he watched both his middle fingers stretch and bloat, his other fingers growing smaller and smaller. Another moan escaped Ben's mouth as it too began to discolour, his nose and mouth starting to twitch with muscle and heat. Looking down he saw his other fingers had disappeared into his hands, his middle finger now as thick as his hand, cracking echoing in his skeleton as he felt his hands stretch forwards. The bones in his upper arms snapped loudly, shrinking in length as he felt them retract into his upper torso, his shoulders starting to crunch and broaden. Ben heard a loud “Riiiiip!” as his t-shirt tore apart from his expanding chest, ripping down the middle and falling down his lengthening arms, leaving his upper torso bare.

“Ohhh don’t stop! Please more!” Ben begged, his change occurring faster due to the introduction of Peter’s powerful cum, his hands now deformed masses, his fingernails starting to take shape into hooves, the flesh filling behind them as the bones reshaped inside his new forelegs. His elbow cracked into his torso while his hands lengthened his lower arm and hands now his upper and lower horse leg. Ben smiled as he felt his hooves dig into the dirt for the first time, unable to feel anything beneath his new hooves but still able to feel the vibrations. His skin began to darken down his sides as fur spread along his hips to meet the fur growing on his asshole. Ben watched as his skin darkened along his new equine legs, his body growing larger and heavier, feeling his back press up against the belly of his equine friend. Fur finally covered round Ben's hooves leaving his legs almost completely equine, his feet starting to crunch and change. Ben’s change seemed to be occurring much faster than before, it seemed that their quick sexual intercourse was a fuel for the change, and Both Ben and Peter were loving it.

“Ahhhh....ohhhhh....I’m your’s my stallion!!” Ben moaned as Peter’s thrusts became faster and more powerful as Ben increased in size, his midsection now bulking up with muscle and flesh. Ben was now significantly larger than before and his belly and waist was a little smaller than Peter’s, his legs starting to lengthen as his forelegs continued to do. Peter got a small shock when he felt his front hooves lift off the ground, Ben supporting his weight under his new muscular upper body and horse legs, his ass still being pounded by the slightly larger stallion. Ben felt his torso bulk up with muscle and power, his pectorals stretching into the middle of his chest as his legs pushed out in front of him, his upper body and midsection now completely equine, his rear not far behind. Ben smiled and moaned as his feet pressed into the soil, making him stand on his tip toes as he felt his toes crack loudly. His middle toe began to thicken and grow on each foot, pushing the others aside as they began to retract into his lengthening foot. Ben groaned as he felt his nose and face warm up, the skin darkening and changing as they thickened with muscle also. Ben gasped as he felt his upper rear human legs crack, starting to retreat into his equine flanks like his upper arms had done before. His foot now as thick as his lower leg, the nail on his toe now starting to resemble a hoof. Black skin and dark bay fur began to spread down his legs towards his new expanding hooves, his upper human legs retreating further into his body as he stood digitgrade, forcing Peter to mount and fuck him like he would a proper horse. The last patches of human skin were covered with dark orangey fur as his rear legs cracked loudly, now completely equine.

Ben could feel his prostate being pounded repeatedly by his big sexy stallion friend, his own body not far off completion. Ben felt his cock slap against his belly while the once human Arabian stallion fucked his stretched stallion ass with his larger erection. Peter whinnied as he felt himself come close to orgasm, his cock shuddering with pleasure as he felt the large beast under him groan as his voice began to shift. Ben groaned and felt his face start to push out, his mouth and nose growing and bloating with size as his skull increased in size. His lips thickened with sensitive but accurate muscle, his nostrils changing shape to a more bestial and animalistic shape. More muscle rippled along Ben's thickening neck, his head starting to move forward as his vertebrae expanded, giving Ben a long and powerful equine neck.

“Ohhh Peter...I'm yours....I want this....nooo don’t stop....nnnnNNEEIIIGGHHHH!!” Ben whinnied loudly, his neck and vocal cords stretching and changing, his last words distorted as he let out his first equine whinny. Peter continued to pound Ben's thick black asshole, his prostate finally giving into the punishment and making Ben’s horse body shudder and shake with pleasure as he cummed. Ben felt his legs shake, his hooves pressing into the dirt as he felt a powerful pulsating orgasm race through his own body. Peter wasn’t far off too, his own orgasm making him whinny in pleasure as he pumped thick horse cum into his asshole, making Ben whinny louder in pleasure as his nose cracked. Ben's face and jaw snapped loudly, the bones reconfiguring as he felt his nose and forehead grow wider, the skin turning black as his face grew forward. Ben whinnied again as his cock spurted thick cum into the grassy dirt, his face snapping and cracking forward. Ben pulled his sensitive prehensile lips back and exposed his changing teeth as he whinnied and orgasmed, the incisors changing and becoming thick flat slabs. His tongue grew longer within his mouth and reached his new flat horse teeth, his face reaching full length as his eyes pushed to the side of his head. Ben looked out of his changing eyes and saw the world in a new perspective, his iris's expanding and taking up his whole eye; giving him an animalistic look. His pupils followed suit and changed shape, moving from a round black hole to a long rod shaped hole instead. 

A loud whinny from Ben and Peter echoed in the field as the rest of the horses watched, the last parts of human skin covered over by his bay fur and dark horse skin. Ben was changed; turned into a beautiful bay stallion with a deep flowing black mane, only slightly smaller than his Arabian lover above him. Peter nickered and pulled his thick equine erection out Ben's worn matt black ass and dismounted, moving along and clopping along next to his new horse lover.

Ben felt his mind sway with new horse like urges and instincts, but still retaining his human thoughts and intelligence, happy in his new form as a stallion. He nickered as he felt Peter rub his neck against his own in a sign of affection, both their tails flicking and swatting off the occasional fly.

Both brand new horse lovers clopped over to the empty shopping bag and food that lay on the sheet, both starting to devour the apples and discard the sandwiches. In many regards Peter had achieved what he had set out to do, he wanted to eat a meal with Ben and possibly get somewhere with his feelings.

He had done more than that; they had bonded beyond the confines of petty human emotions.

They had become something far greater than human, something beautiful and magnificent.
