Michelle's lustful hunger disapeared as she stumbled into her feet, shaken by the experience, what happened to her? Was the water responsible for this? But more than the thoughts of worry and the implication of the water was the building heat flowing through her veins and... A tingling in her body. A much more powerful flush of arousal stroke her, Michelle couldn't do anything but move her right hand to her breast, and begin to massage it, it felt too good, better then it should have, and before she could notice, her body started to change, her ears slowly grew as the nails of the hand that was massaging her breast were hardening, turning into a black color.
"Oh gosh... Wh-What's happening..." Panted Michelle as she pleasured herself, it was too much to resist, the urges were way too strong and too demanding, Michelle quickly took off her pants as she introduced her untouched hand in her panties massaging her nethers to satisfy her crying needs.
But Michelle suddenly stopped her ministration as she felt something pushing her finger away from her slit, "Hu-huh?" said Michelle in suprise, while she was pleasuring herself, the changes that were unknown to her accelerated, her right hand fully shifted into a black hoof, meanwhile the rest of her changed hand was being covered with black fur, while also a tail slipped out of her spine, almost fully covered in longer and much darker black fur, suddenly her innocent panties felt tight, way too tight, she saw and felt a bulge developing in her nethers, a small black patch on the center of her panties, the bulge kept developing, thick and throbbing, while she was staring at the bulge, her legs grew in muscle, her feet completly cracked and shifted into black hooves as the same black fur that covered her right hand also covered her legs.
Michelle was still giving a stunned look at the bulge growing in her crotch, she touched the black spot on her panties, it felt like something.... Wet? Michelle was slowly starting to panic, the changes slowly reached her ass, as it slowly began to expand, she then felt something warm pressing against her tights, it weren't her panties, it was something warmer and bigger, eventually her panties were completly destroyed, revealing a throbbing equine cock!
"Kyaaah!" Screamed Michelle, as she saw her new cock, which was dripping with small droplets of pre, by just looking at it, she felt needy, way too needy, she wrapped her left hand which was untouched by the changes around her new member, stroking it with desire, while pleasuring herself, the changes slowly reached her torso making it grow longer and heavier, her breasts completly vanished as black fur slowly traveled up to her entire torso, "Aaah... Hng... Yeeeeeeigh!" groaned Michelle as her member erupted with strands of equine semen.
After this short climax, Michelle felt a powerful masculine call as her apple sized testicles dropped down, still filled with equine semen, she took her hand off her throbbing member as it quickly cracked and shifted into a hoof, her back suddenly arched as it tore the rest of her shirt, revealing that fur completly covered her back and torso, slowly reaching her neck, "W-WHAT?!" shouted Michelle, she got too carried away with her lust that she didn't even realize that her body was almost completly changed into one of a male horse, a wave of pain struck her back as she fell on all fours, incapable of standing on two feet again.
"No.. Neiigh... I don't want to be a.... N-Neigh...!! I don't want to be a male horny horse!!!" Shouted Michelle as she whined through most of her sentence, her face painfully cracked as fur slowly covered it, meanwhile her or rather his hair grew, resembling a beautiful midnight black mane, he felt a powerful burning sensation coming from his head as two longed curved horns pushed out, Michelle shut his eyes tightly as his face pushed out, his nose completly disapeared as it leaved two nostrils behind, meanwhile his jaw cracked as his teeth reshaped into ones of an equine.
Michelle was not completly changed into a demonic stallion, but there was one last thing unharmed, his mind, he struggled to keep his eyes closed to not see in what a horrifying abomination he just turned into, but his mind was starting to be filled with much worse feelings of lust and erotic pleasure, he suddenly openned his eyes widely, revealing evil red eyes, Michelle rose up to his hind legs legs as he let out a powerful whine, his member erupting with strands of equine semen.
