Pony snuck out of her dorm. It wasn't the first time, and despite what she may want, most likely won't be the last. She crept through the deserted halls, illuminated only by the moonlight. She was lucky enough to not disturb anyone as she exited the building. Once outside, she could move a little faster. It was about a half-hour walk off-campus, to the closest farm. At least the closest farm that had what she wanted.
She quickly made her way there, avoiding the streets out of fear of being seen. There was very light traffic at this time of night, only the occasional car in the distance. She finally got to the perimeter of the farm she was about to sneak onto. A chest-high barbed wire fence spanned in both directions as far as she could see.
With some agility she hopped to the other side, being sure to not knick herself on the blades. She was lucky, it was a full moon tonight, and the moonlight bathed the property enough to make out distinct silhouettes. Even from far away, she could make out the stables. She made haste to cross the field to the building, knowing that she was now trespassing. She arrived at the building and gripped the handle of one of the big, sliding doors. She opened it just a crack, gritting her teeth as the wood moaned. She slipped inside and shut it behind her.
The stables were pitch black, but she had an answer for that as well. She knew the farmer kept a small lantern just inside the door. She fumbled in the darkness to find it, pulling it from the nail it hung on and then pulling the small lighting from her back pocket, flicking the flame to life before lighting the lantern. It was a dim light, just enough to see, and hopefully, not enough to draw attention.
Once the lantern was lit, she looked around, and just as she expected, found the half-dozen stallions she had become acquainted with these past few months. She slowly walked down the middle isles, petting the stallions' noses as she passed, greeting them. Most of them were geldings, only one of the stallions, Brutus, was still intact. Pony knew the farmer used him as the breeding stud and, well… She hated to admit it, but her quirk affected her in all sorts of unforeseen ways. Including having an estrus cycle.
Every so often she would go into 'heat' and would be inconsolably horny and pent up. It was agonizing, for years there was no relief. Until she came to U.A. She found out that there was this farm, and that there was a large stallion, with all his parts still attached. Curiosity got the better of her one day and she visited. That was the first time she laid with him.
Brutus was a gentle, caring lover, for the most part. Pony frequented his stall whenever she was in need, and he was more than happy to oblige. All it took was a couple of whiffs of the pheromones Pony's body was giving off to get him revved up and ready to go.
As she arrived at his stall he whinnied quietly to greet her. He was happy to see her, in no small part to becoming conditioned to know what came next.
"Hey, big boy." Pony whispered, laying her hand on his nose.
She set the lantern down in the corner of the stall where it wouldn't get knocked over. Beside the wall of the small area was a bench, she gently slid it away from the wall and towards the horse before sitting down on it. She ran her hands down the stallion's sides, feeling his musculature. She eyed his strong legs before her gaze wandered lower, to what was hiding underneath.
Two avocado-size testicles sagged slightly in the horse's scrotum. In front of that, his sheathe. Inside was hidden what Pony was after. She could feel her muscles tense slightly in her lower abdomen just by looking at it. She bit her lower lip in anticipation.
She knew that she needed to get him riled up before anything could happen, though. So, she stood and quickly disrobed, hanging her shirt, pants, and panties over the stall wall. As she removed her underwear, she could see she had already started to soil them with her juice. A sign of how badly she wanted this.
She walked in front of the horse, her bosom pressing against his nose. She could feel the area between her legs start to flare with heat. The excitement of being naked, trespassing, and possibly getting caught always turned her on even more. Brutus pressed against her soft skin, lowering his nose to her thighs, and flaring his nostrils. He neighed and moved his head back up, licking Pony's stomach in the process.
Pony giggled but knew it was time to get to work. She walked around the stallion, sitting back on the bench. This time she saw what she desired. The head of his dick was starting to poke out of its sheathe. Slowly filling with blood, she knew it would be fully erect in less than a minute. She was greedy though, and reached out anyway, gripping his semi-soft penis. She ran her hand down the length of the shaft as it grew, feeling the heat, and the pulse from the veins that began to protrude from under the skin.
She worked his cock, back and forth until he was at full length, his dick hanging more than halfway to the floor. Pony licked her lips and stooped down off the stool, getting on her knees under the beast. She pressed her body into his member. Her face mere inches from the base. The tip of his dick pressed firmly against her stomach.
With one hand, she kept the horse's penis pressed against her body, and with the other reached up to cup his balls. She gently rocked back and forth on her knees, sliding the dick along her body as her free hand caressed and massaged his testicles. They felt heavy. Full of spunk.
His musk was overpowering. The same way her pheromones had gotten him excited, his smell was making her sex spam. Demanding to be satisfied.
Unable to hold on any longer, she let go, stood up, and pulled the bench closer. She laid down on her back, spreading her legs wide off the end. She reached down and grabbed his massive dick before lining the head up with her needy pussy. She rubbed the head against her lips a couple of times before Brutus got the message. He began to slowly thrust his hips forward. His cock slipped and slid up onto Pony's belly.
She realigned and tried again. This time the head sank between her lips.
"Oohhhhh….." Pony let out a muffled yell as she felt his cock head slide inside her. It was massive, it stretched and spread her out just right.
Brutus continued forward, slowly sinking deeper and deeper inside. Far deeper than Pony could ever expect a regular human boy to go. Once he reached as deep as Pony could offer, his member's head rubbing against her womb, he started to retract. Pony's walls clung to him fiercely, resisting him from leaving, but that just made it feel all the better.
Brutus started breeding Pony. His massive horsecock pumping in and out, back and forth, it was big enough in her petite body that a bulge was visible on Pony's tummy.
Pony tried to contain her moans as much as possible, biting onto her finger as she got reamed. But after a small amount of time, she was moaning loudly like any slut. It didn't take long at all for Pony to cum. She felt her muscles contract and hold the horsecock in a tight vice grip for a few seconds before relaxing and letting Brutus continue to ram into her guts.
As Pony was painfully aware. Stallions don't have the kind of stamina that humans do. After only a couple of minutes of pumping her pussy, his balls contracted, and he orgasmed. Firing a full liter of watery cum inside her spurt by spurt. Pony obviously couldn't hold it all, and once her womb was filled to the brim, it came back out, flooding past his cock, smearing his balls with the splooge, and forming a large puddle on the bench that then leaked onto the floor below.
As Brutus's cock deflated, and pulled itself free from Pony's quivering nethers, she simply laid there, thoroughly satisfied. Her breathing was rapid and uncontrolled, her legs were weak and shaky. She could feel the semen continue to ooze out of her and hear the drips of it as it splashed down to the ground.
She laid there for a few minutes. Basking in her orgasms before her breathing returned to somewhat normal, and she got the strength back in her legs. She got up, thanked Brutus for his hard work, put things back the way she had found them in the stall, and covered the cum stain with some nearby hay. She slowly got her clothes back on. She knew the horse's cum would keep leaking out of her and ruin the panties, but it was worth it. It felt nice.
Once clothed and ready, she left the stall, extinguished the light in the lantern, and hung it up before exiting the stables. All she had to do now was make the long trek back to U.A. and sneak back in without anyone catching her.
Shouldn't be too hard right? She had done it before, and she will probably do it again.
