?"Whew, I think it's about time I hit the hay!" Sarah said to no-one in particular, slumping back into her recliner as she stared up at the ceiling. She had spent the last few hours tending to the horses under her care, making sure they were well fed, cleaned up, and staying in stables that were neat and tidy. She knew tomorrow would be a little bit harder for her, as she needed to pair some of them up for breeding, and whilst she had handled a lot of things at the stables before, she was yet to do anything in regards for getting them to mate.

"I'll have to take another look at those notes tomorrow, can't be that hard, can it?" She muttered under her breath - how hard could it be, really? All she had to do was pair a stallion with a mare and watch nature take its course. She recalled that sometimes there would be the need to give assistance, but she hoped that she wouldn't need to step in that far. Whatever she had to do, it wasn't worth worrying about right now.

Sarah got back to her feet, the thought of taking a nice, long shower before going to bed crossing her mind. Before she could do as much as take off her shoes, she heard a whinnying noise coming from outside, catching her attention.

"The hell was that?" She asked, quickly heading out of the house. "Don't tell me they couldn't even wait till the morning before they tried anything!" As she got to the stable, she noticed that the gate was open. That shouldn't be, she thought, having closed it up around half an hour prior. She headed into it, taking a look around to see if anything was out of place. Not even a few steps in, and she spotted what appeared to be a backpack placed down on the other side of the shut door, a pair of shoes set next to it.

"What, someone trying to camp out in here?" She looked over the stables, trying to find the culprit, only to be cut off by loud neighing from the stable next to her, the individual gate open. Perhaps the person who broke in was trying to get the horses to breed themselves, maybe for their own pleasure. And indeed, from what she caught at first glance, was the sight of a horse on top of one of the mares.

"Alright, you sicko!" She stepped around into the stable, "I'm onto your little game, so why don't.. you..." Her angry words drew to a pause as the stallion on top of the mare turned around to face her, and to her confusion, said horse had a human head, albeit one with pointed, furred ears and a long, luxurious mane. "What the...."

"Hrhhr..mhrhieiegighhhh!!" The human-headed horse moaned and whickered, thrusting harder into the mare as his jaws pushed forwards, head reshaping into a broad, equine muzzle, nostrils flaring and teeth flattening, his eyes moving towards the sides of his head, pupils pulling into sideways rectangles. He snorted and moaned as he kept up what he was doing.

"I.. I must be seeing things..." Sarah couldn't quite believe what she was seeing. Only now could she also see the torn clothing hanging from the horse's body. The creature must have snuck in whilst human and began mating with the horse as he was turning, or maybe even beforehand. She was so confused by this that the only thing that broke her out of her shock was when she felt something warm and sticky splat against her face and mouth. "Mmmph, what the?!" She gagged, swallowing some of it as she looked up to the ceiling. From one of the metal girders, she saw a thick, white liquid dripping down from it, some of it landing on her whilst the rest landed around her or on the breeding horses. The best guess she could give is that the beast before her was the one that made that mess.

"This is just bonkers.. I should really break this up before any-oooooooohhh!" A groan left her mouth as a sudden burning sensation filled her body. "Th... that... what was that?" She asked, body tingling as she looked over herself. Her gaze almost instinctively went towards her hands, dark-brown hairs sprouting from the wrists, growing in along her arms and over her hands. Her fingers felt stiff, the middle finger ballooning in size, whilst the other digits receded into her hands, the nail growing thicker and harder, enveloping the remaining digit, leaving her with a pair of equine hooves.

"Gh... what... why do I have hooves?" She gasped, looking at them in disbelief, the fur continuing its growth. Her shoulders grew broader, the sleeves of her top splitting under the growing mass, revealing her bulking arms. Her upper torso was becoming more muscular, her chest barrelling with every breath that she took, her breasts soon bursting through it. She moved her hooves to feel them, only to find they were shrinking, vanishing away.

The stallion was looking at her intently, all the while still thrusting the mare beneath him. He appeared to be smirking, Sarah's body stretching taller, as if someone was pulling her spine, tugging it so hard that it was now protruding past her rump, thick hairs sprouting from it as it formed a long, flowing tail. Her lower body was catching up with her, stomach gurgling as it grew slightly more rotund, her body becoming unable to support her weight on two legs, making her fall forwards onto her hooves.

"Hh..hhreiighh... and why... why does it feel so good?" She huffed, looking at the stud. Her loins burned, her lust skyrocketing, making her thrust her hips forwards. She was wishing she still had her hands so she could properly work herself over, and as she thought that, she felt an odd, pushing sensation filling her groin. Craning her head down, she looked on in shock as she saw a large, thick, mottled horse cock working its way out of her most personal of areas, the lips closing up as a pair of coconut-sized balls plopped outwards, dangling between her thighs.

"Hrhhr...RREIEIEIEHEIEHEHEH!!" He instinctively reared up, forelegs kicking against the air as he fell forwards onto the stallion, his hooves resting on his shoulders. What was left of his skirt and undergarments tore off around his squaring, expanding ass, his feet kicking against the ground as he wasted no time in guiding his hefty dick hard into the stud's rump, causing the beast to whicker out in pleasure. As Sarah took him, he felt his legs bulk up further, giving his body the extra support needed for his heavier frame, his malforming feet bursting out of his shoes, revealing large hooves.

"Mmrrahaheiighhhh!!! Yhhhrheheaheheessssss!!" Sarah cried out, trying to speak but finding it increasingly difficult, his vocal chords altering as his neck stretched and thickened, carrying his head away from his shoulders, at least a foot and a half long. His previously shoulder-length hair now grew down towards his equine shoulders, ears growing to points as they moved to sit atop his head.

Another distorted moan left his mouth as his jaws pushed outwards, stretching into a broad muzzle, nostrils flaring wide. His teeth moved towards the front of his new maw, growing broader and flatter in the process, lips thicker and darker. To end his changes, his eyes moved towards the sides of his head, turning a bright red with vertical pupils.

"Hhrh...hrreiighhh..." The horse that was now Sarah moaned and whickered, thrusting harder into the stallion, who was in turn thrusting into the mare beneath him. The three beasts rode each other harder and faster, their moans and cries coming faster and more frenzied, eventually ending with the three beasts neighing out in pleasure as they reached their respective orgasms, Sarah cumming hard into the stallion's rump, whilst the stallion came heavily into the mare's warm folds.

The three slowly came down from their highs, the stallions pulling out of their respective partners, the studs looking over each other with a smirk. Their cocks were still hard, and there were still many mares in the stables that could do with a good breeding. Not to mention that it'd save Sarah a lot of time in the morning.
