Zoo Street was a small cul-de-sac road about fifteen miles from the town of Increst, Texas. Eight houses had been built by a land developer with a bold plan to expand the sleepy town. Said plan had fallen apart shortly after the completion of the eight house when the man was struck by a meteor. His son, having no interest in the project, had sold six of the properties and erected a memorial to his father In the cul-de-sac. The memorial had two parts; A granite brazier standing high and tall on a column in the center of the cul-de-sac. At the center of said brazier a crystal flame found within the meteor that had struck his father danced perpetually. Around the tall column that supported the brazier there were inscribed words. “Home and love are things sought by both the beast and man.” These words shimmered in the light thanks to the crystal inlaid into them. No one who lived on Zoo street gave much thought to the monument, it was pretty and well crafted and that was as much as they thought about it. If they knew that the crystal from that meteor was anything but an ordinary stone they might have thought twice. On a particular day in September at around seven o'clock the light from the sun hit the memorial and the crystal words and flame glowed with a light of their own. Ribbons of power danced through the air in all directions towards the houses seeking any living creature and then everything changed. Devin Argrove of fourteen years of age had the dubious privilege of living in the first house constructed on zoo street. A reclusive sort he preferred video games books and endless browsing of the internet to sports and parties. One look at his bronzed skin and runner build and you might mistake him for an athlete. His body type had more to do with the endless parade of yard work he did rather than any effort to be fit. His tan had more to do with his tendency to perform any outdoor work in nothing but boxer briefs than any effort to look good. His long dark hair is the product of being too apathetic to seek out a barber. The strange tendril of light wrapped around Devin before he even knew what was happening. The strange aura soaked into his skin like water into sand. Devin barely had time to process that he was changing at all as the fur deep dark silky and shiny spread across his body. His gums itched as his jawline shifted pushing away from his face dragging his nose along with it. His ears shifted to a point as his changing head came to more closely resemble a beast of burden. His muscles thickened all across his body, limbs flexing uncontrollably knocking him off his feet. His sandals burst apart as his toes curled back against his ankle shifting into hard shiny black hooves. The tail he had just grown strained against his suddenly too tight shorts. Said shorts gave out as the teens cock sprang to full erection and kept going, the head growing wide and flare flat flaring out as he came. Panting Devin leaned back looking over his new cock and the mess he had made before climbing to his hooves. His head was abuzz with questions and new feelings shoving each other to the forefront so fast there wasn’t a chance to even think on them. His nostrils flared as he stood naked in his backyard, the setting sun warming him even as it cast shadows all around. A Scent carried on the wind snagged his mind; he had never smelled anything like it before but a primal part of his mind knew the scent was a mare. Body on autopilot Devin ran to the fence that separated his yard from the Jacksons next door. Peering over the fence he saw her for the first time. Her coat was a rich auburn dappled with white. The pattern was most pronounced on the bountiful breasts she was stroking and across her back side where her tail swung back and forth wafting the scent of her arousal about. She was taller than him by at least two feet, maybe as much as three. Her body wasn’t as muscular in fact she looked down right soft in comparison. As Devin gazed on her his mind was confused but his body was certain. His cock throbbed erect once more, the tip flicking strings of pre-cum in front of him as it bobbed with his heartbeat. The scent must have caught her attention because she turned to him her green eyes deep and mysterious as a rain-forest locked on him. Her ears shifted forward and her lips curled into a smile. “Come to mommy little man.” She whispered, crooking her finger for him to come closer as she dropped to her rump and spread her legs showing off the thick lips of her sex and the winking of her clitoris. Devin hopped the fence in a single bound and closed in with only two thoughts on his mind. The first being that he recognized that voice as belonging to Julia Revendo, the mother from next door. The second and more important thing was that he was going to do whatever she asked of him. Julia devoured him with her eyes and he gazed back with an equal hunger, The difference of course was that he had no clue what to do. “Hmmm yes that’s lovely.” Julia declared reaching up and stroking Devin’s cock a sensation so intense the young stallion fell to his knees. Julia laughed as she used her legs to pull Devin closer, the young stallion's cockhead pressing against the mare's thick cunt lips. “Now… push it in for me, push that big cock into mommy.” Devin of course hardly needed prompting though part of him had at least been waiting for permission. His cock pushed past the lips that hugged to his cock like a vise he slid in until his medial ring pressed against her entrance and he found that even though he had more cock to give he couldn’t push further in. with snort the young stallion simply pulled his hip back and pushed forward. Devin humped and thrust and bit by bit a little more of his cock slipped into the eagerly waiting depths of the older woman her sticky sexual fluids mingling with his as they fucked with abandon on the grass for anyone to see. Not that either of them would stop if they were spotted they were going to finish and nothing and no one would stop them. Devin snorted and huffed as he finally hilted himself in the mare's heavenly depths pausing for just a moment to soak in the sensation of her cunt squeezing tight around his member warm and slick and tugging his cock as if to pull him deeper still. Both of the equine lovers were slick with sweat, the scent of their fevered love drifting through the air. Steam rose from their bodies as the mare hugged the stallion tight to her ample chest. “Cum for me! Cum for mommy!” Julia cried out as her sex clenched desperately seeking to milk the young stud dry. Devin whinnied in reply, his cockhead flaring and balls pulling tight against his body as he flooded the mare's womb. Devin had a moment to recover before a pair of strong hands seized him grabbed at the hips and the back of his neck he was hauled off the mare and tossed lightly aside landing on his rump about a foot away. “You call the fucking?” declared the stark white stallion a full head taller than Julia with rippling muscles who had just forcibly separated the two. “Cause i’ll show you how to properly fuck.” He declared hoisting Julia to her hooves and pushing her up against the fence. The mare seemed more than a little turned on by the rough treatment. “Pay attention son. This…” the stallion grabbed his sheath rubbing it until his cock emerged and stood proudly before him Devin felt equal parts ashamed and aroused looking at the member. “...Is how you properly fuck a mare.” he declared pushing his cock into Julia’s cunt hilting her in one clean motion. The stallion snorted as he grabbed hold of her hips and began to rock his hips putting more force into each thrust until Julia had to brace herself against the fence to avoid being knocked over. The mare whinnied in delight, her breasts shaking as the stallion staked his claim on her body. The white stallion leaned over her back, his hands sliding along her flanks as he switched to grinding his cock deep inside of the mare. His hands roved up her belly to her chest and took hold of her swaying breasts roughly squeezing the mounds. His fingers curled into the tender flesh of her breasts in a way that looked painful but judging by Julia’s reaction was anything but. The mare's tongue lolled from her head as she panted breath stolen by a second orgasm. The stallion snorted as he revised his grip grabbing Julia’s thighs and hefting her up in the air holding her body up on his hips. Devin had an uninterrupted view of Juli’s rapidly winking clit and the way her lips were parted by the older stallion's cock. The younger stallion was rock hard watching the scene, drooling slightly from both his lips and cock. The stallion huffed starting to work up a lather himself and so he flipped the mare forward still keeping her cunt impaled on his cock as she held her front end off the ground with her hands. Julia let out a whinny of pleasure as the stallion finally came, letting her slide to the ground with his seed oozing from her slit. Devin looked from the nearly insensate mare on the grass and then to the stallion. More specifically that at the cock that was still standing proud. “You want a turn?” Devin’s thoughts were interrupted or perhaps anticipated by the stallion. “Turn around and lift your tail. I'll show what she felt.” Devin hesitated before complying. Devin’s tail hiked up almost of its own accord as it occurred to him where that big cock was going. The younger man let out a squeak as his cheeks were pried apart and the slick sticky head of the older stallion's cock pressed against his virgin backdoor. The pucker of Devin’s ass gave in to the studs dick with surprising ease. The young man sucked in a long breath as his cock spurted ribbons of pre with each inch of stallion cock that filled his rear. Devin came as he felt the older male's hips rest against his own. Devin gasped with delight cumming as the stud gripped his hip and shoulder and gave a simple short pump. Devin felt a bit of the shame from earlier come back but only for a second before the pleasure shut that voice up forever. “More please Daddy.” he begged with a moan. “Sure thing son.” the stallion said as he began to fuck Devin’s ass properly. “Just remember to keep moaning for me.” Devin had no problem complying with that request; the feeling of the older stallion filling him drove rational thought from his mind. The young stallion gripped his cock pumping it in time with the thrusts from Daddy coaxing huge spurts of precum from the tip. Devin’s legs shook and the only thing keeping him up right was the firm hands guiding his ass up and down that cock. The younger stallion neighed as he came again, his cock twitching as he emptied his balls onto the ground, his cock falling limp in his grip. Devin gasped and moaned as the older stallion continued to make use of his ass. Devin’s erection had faded but the warm tingly pleasure of his previous orgasms was still rolling through him. The older stallion pulled Devin back against him, his hooves dangling off the ground as his back was pulled tight to the other man's chest. The stallion grunted and a warmth blossomed in Devin’s guts. The stallion tenderly lowered the boy to the ground but Devin collapsed to the ground anyway. “Phew. gonna need some protein and water before we go again…” the stallion said and began to trot into the night. Devin and Julia shared a look climbing to their hooves and following after the stallion at a trot. The trio of horses hopped the fence (not because it was locked merely because they could and it was fun.) and carried on across the street. The still glowing memorial was the only light on the street so it was a touch of a surprise for Devin and Julia to realize they were standing in the house belonging to Zoo streets resident bachelors, Kyle and Kevin. “Kevin, things are weird outside, so I went looking for help.” Kevin smiled as he locked the door pulling the other horses into an embrace kissing Julia deeply before leaning down to give Devin an equally passionate kiss. “Okay but seriously water and some food before we get back to it.” he declared before moving into the kitchen. Devin only realized that he was naked when he went to use the bathroom. He brushed off the discomforting realization with the fact that he was a horse and they didn’t wear clothes. Formal introductions were made as the group had a dinner of eggs, orange juice and premade cinnamon buns. Despite knowing each other's names, none of them really felt like using them. Instead Devin couldn’t stop calling Kevin Daddy or Julia Mommy. Likewise both of them kept referring to Devin as son or to one another as darling. As soon as the meal was done things picked right back up. Kevin dropped himself on the couch, legs spread wide and began rubbing his sheath until his cock stood proud once more. “Hey darling, why don’t you have a taste of the family jewels while we see if the boy learned his lesson.” Julia grinned climbing onto the couch she took Kevin’s cock in hand kissing the tip before sliding her tongue out to curl about the head. A smack of her rump drew Devin’s attention and the stallion hurried to join the fun.
