Mika fell, choking as a searing burn filled her chest. The unicorn screamed as he pulled free his horn and stood over her. She looked up at him, and even with her last breath she couldn't believe the perfect aching beauty of the creature. But her body refused to die as the burning spread. Through the tears that leaked down her face she saw her fingers grow together into cloven hooves and snow white hair begin to spread up her arms. Her body convulsed uncontrollably and she screamed in pain as her bones ground together, crushing her human form into a new shape. The stallion behind her didn't bother to wait. He leapt upon her, his weight pressing her down into the grass as his hot erection slid free to thrust between her still human thighs. He sought the soft warm opening in her changing body as she struggled beneath him. She fought to escape, struggling as his greater size and strength pressed against her still half-human form.
The unicorn clutched at her body with his front hooves, and pulled her tightly against him as the tip of his phallus probed for her slick opening. At last finding what he needed, he thrust forward, sinking deep into her virgin body. She screamed again and dug her hooves into the soft loam, lunging to escape. The stallion moved with her, groaning as it thrust again. She bucked and twisted against his hard body, but no matter what she tried there was no escape from his violation. He throbbed inside her, plunging repeatedly into her as her new equine body formed around him. She shuddered and spasmed as he rammed forward again and again, his moisture slickening her sensitive, swollen interior. In horror, Mika realized that she was starting to enjoy the rhythmic thrusting as the unicorn stallion fucked her into submission. Not all the moisture was from the stallion's pulsating hardness inside her, and she found herself pushing back against him, bracing her legs to meet his thrusts. She no longer drove to escape him, instead she found herself needing to feel his next thrust deep inside her.
She lowered her head to the cool grass as her body grew slick with sweat, her heart pounding in desire. She leaned into the animal thrusting behind her and pushed back against him, squealing in pleasure. Her lust overwhelmed any of her remaining human thoughts of revulsion and she spread her thighs wide, arching her back to give him room. He paused as she gave in at last, and she whimpered and pushed back against him in raw craving as he stopped. That was the signal he had been waiting for, and he bit at her finely arched neck, thrusting deeply into her dripping passage as she squealed and quivered. She screamed her final pleasure, her body throbbing in release as he spewed his load inside her. She stood sweating and shaking, her head lowered in submission as he pulled himself out, leaving moisture trailing down her gleaming white thigh. Behind her, he sniffed at her swollen throbbing slit and ran his tongue over it, tasting their mingled juices. It sent a wave of pleasure and mindless lust coursing through her body and she immediately felt herself responding to his touch.

He never had to lure them into the dark forest, they always followed him willingly. This one never even glanced back to the shreds of her clothing, or her gleaming camera lying in the middle of the glade.
