The Pony Transformation

The Mount

Lightning didn't know what to expect as Maddy slowly unlocked the large sliding barn doors. This barn seemed more secure as she slid them open, revealing what was inside the room. The floor of this room, instead of being wood or concrete, was covered in thick blue tarp, and the walls were made of red wood panels that kept the inside of the barn relatively warm. In the center of the smaller barn were two girls, and one he recognized as his handler from last night, cait, and the other was a taller girl with blond hair, who he knew as Sarah. But what interested him most was what they were toiling away at in the center of the room. Standing at waist in the center on four wooden legs was a long, brown cylinder coated in what looked like cowhide leather. Facing lightning, sticking at the end of this long cylinder, was a round, perfect hole surrounded what looked like a ring of clear rubber. He suddenly realized what was going on, and almost smiled through the bit; they had brought him to a breeding mount for horses.

Maddy looked behind her, seeing her ponyboy's eyes widen. She smirked gently and led him closer to the mount, handing his reigns off to cait. She could tell he was an excited pony, he was moving with a lot more fire and seemed almost ready, trying to stare down at the inviting hole through his blinders. Sarah spoke to him as Maddy started to further prepare the mount, adding some necessary straps. Sarah wore a black leather apron over her clothes and a pair of blue medical gloves as she kneeled down in front of the pony. "Now pony, this isn't a real mare because we don't know if you meet the specifications to breed yet, we're just gonna test you out and see how you produce." He could barely focus on her words as he was so riled up, his cock straining to escape painfully against the metal tube. He had been so pent up, itching for any sort of relief. Sarah grabbed the ancy pony stallion by the side of his harness, turning him around so that his muscular, latex ass faced her. She looked up at his tail, slowly reaching her gloved hand up to grab the base. Lightning swayed slightly, wondering what she was doing back there as his vision was thoroughly blocked. Just then, cait, dressed in a similar black latex apron, stepped in front of him, holding a larger, more intimidating crop. She made sure to show it to the pony, before speaking in a deep voice that sent shivers down his spine. "Don't you dare move while cait does her business back there no matter how uncomfortable it is, or you will feel this crop against your sensitive stomach pony, and you will loose out on being able to have a go at the mount. We don't like wiley stallions here..." with those words Lightning sucked in his breath and stood tall and proud. He wanted the mount so bad, no matter how degrading it might be to be milked like a horse with a fake plastic mare. All that mattered was his relief.

Sarah slowly but surely pulled on his tail, letting the thick, black plug slide painfully out of his hole. A light grunt and huff erupted from the pony as his horny, needy cock throbbed painfully into the metal sheath behind the belt as his hole was stretched. Sarah smirked as she casted the tail to the side in a soapy bucket for cleaning. She then squirted some clear lube from a bottle onto her gloved hands. She rubbed her hands together to make the cold lube a bit more suitable, before taking two of her gentle fingers and gently pressing them against the ponies ring. He hated this part, clenching gently as he stood still, but as she warmed him up, doing brief soft circles around his hole, he slowly relaxed. Once she felt he was relaxed enough, she slid her two fingers into his warm insides. She smirked gently as she could feel him quiver and jump at the unwelcome invader, but that didn't stop her. She felt gently around his walls, checking the potential stallion, and testing his tight, warm behind. She pushed deeper and deeper, despite the obvious reprehension of the large latex pony in front of her, until she found his g-spot, a small bean inside his hole. She giggled slightly as she felt it, checking the pony and sliding her gloved fingers back and forth against his prostate. Lightning felt like he might explode right there. He had never felt so much pleasure shoot through his body as he let out a loud, girly moan through his bit. Pre leaked out under his belt and dotted the tarped floor as his legs gently shook. His cock strained hard, throbbing and trying to fight the metal as the pleasure surged into him. His balls ached, but he knew despite this he couldn't cum. He wanted her to stop, his frustration was boiling as his dick painfully tried everything to get erect. She smiled as she slowly pulled her hand out of him, removing her glove and casting it aside. She then picked up his soaking tail as Lightning panted heavily, letting out a few final drips of pre on the floor. He needed to fuck that mount, he wanted nothing more than to shoot his seed into the breeding bench. Hell, he might even sacrifice his freedom for it, anything to relieve the swollen, aching pain on his cock and balls. Sarah spoke as she lifted up the tail, sliding it back in to his warmed up behind, "everything checks out, but by his reaction to that he might serve better as a mare," she joked to her fellow trainers as she finished up and stood up.

Cait, gripping the crop forcefully, now took his reigns, leading him over to the mount so that he faced his new girlfriend. The taller girl first unbuckled his reigns, instead attaching a leash to his collar and down to the other end of the mount. Meanwhile, his owner Maddy was busy buckling his harness to the collection machine. He was positioned so there was almost no slack in the line, and his hips were forcefully pressed against the back of the mount, so even if he wanted to pull back and out of the hole he couldn't, most likely to guarantee all his pony seed was collected. lightning thought this extra restraint was, well, a bit extra, but what came next was even worse. His already cut vision was brought down further when a thick sheet of fabric was placed over his eyes and tied, effectively blinding him. Below him, cait was hard at work. She first connected his ankles together by a short chain called a hobble, to make sure he couldn't move further, only able to thrust in and out. Finally, he was ready to breed.

Cait, already on her knees next to the belt due to having to hobble lightning, reached up with her masterkey used for all pony chastity belts. She unlocked a front panel, dropping the metal frontal plate down, which let his pent up cock and balls breath for the first time. The front plate hung down, but remained attached. Lightning sighed a sign of relief as his cock shot to life, immediately hardening and throbbing. It pointed up, right outside the gaping, hungry hole of the breeding mount. Cait laughed gently as she looked at it, lubing up her re-gloved hands, "not working with much are we stallion?" She smirked as she gently rubbed the lube onto the soft, silicon pocket pussy, making sure to get the edges. Then, she gently grabbed the base of Lightnings member, positioning his pink tip against the circular hole.

It didn't take much convincing as cait removed her hand and stood up to watch. Lightning quickly thrusted into the soft, warm hole. He thought he might cum right there. The inside of the mount was filled with grooves of wavy pleasure that send shivers down his spine. He had felt so pent up that nothing in the world was better than this tight mount, his head went blank as he moaned out through the bit and started to shift his hips back and forth as far as he could go. Each thrust caused his body to erupt in pleasure, leaking pre into the collection chamber as he fucked his pony girl. His legs gently quivered as his muscles flexed beneath the tight white latex, each thrust bringing him closer and closer to completion. The girls watched together, gently mumbling about his form and posture as the blindfolded pony shifted in and out, moaning and hugging at the pleasure his thick, swollen member felt. He inches closer and closer to the edge until the unthinkable happened. He felt himself forcefully thrusted into the mount, his straps tightening and locking him unable to move with his cock deep inside the mount. He whined out as his cock was devoid of pleasure, but spurted to life. With one twitch, he shot his ruined orgasm into the mount. He never reached that final plane of orgasmic pleasure, just the twitch of his cock as he shot his pathetic load into the fake beast. He whined and cried out, stomping his hobbled feet, trying to do anything to push himself over the edge but it was gone, his pleasure ruined.

"I'm sorry lightning, this milking isn't for your pleasure... from the looks of things you're just not meant to be a stallion it seems." He whined again with frustration as Maddy spoke from under the fake horse, unscrewing the half full bottle of white, sticky pony seed. "The more pent up I keep you pony, the more obedient you'll be" she took the bottle and walked up to the stick pony, his swollen cock now slowly returning to its soft form as she unscrewed the bottle in front of his face. He couldn't see what was happening due to the blindfold, but from her voice he knew she was close to him. "And it seems this seed is now worthless, we can only get good money for stallion seed..." with that she lifted the bottle to his lips. Lightning could feel something warm on his mouth in front of him, but he didn't expect his bit to soon be soaked in an unknown liquid. He gently tasted it with his pinned down tongue, but before he could react to the salty taste, his entire mouth was filled with a warm, sticky liquid. Was that his own seed? He tried to spit it out, but Maddy kept pouring as the bit only let it in, and became soaked in his own cum. He gagged slightly, but soon started to swallow quickly, wanting to do everything to get the foul taste of salty pony cum out of his mouth quicker. After finishing off the bottle into the equines mouth, she motioned for cait to buckle his belt back on. Lightning was too focused on trying to remove the white seed stuck to his bit, he almost didn't feel it as cait stuffed his soft, disappointed member back into its metal prison, and locked the front, unforgiving panel back on.
