Story: Scared and Horny Werehorse TF on Halloween (Patreon)

She got separated from her friends walking back from a Halloween party. She stumbled through a courtyard, finding her way by the dim light of jack-O'-lanterns. A dizziness hit her. Too much to drink perhaps?

She lost her balance, fell to the ground. Then her body began to grow. Her muscles flexed and spasmed under her skin as they swelled with power. Her shirt and pants ripped at the seams and fell away. Her nostrils expanded, widening with each panicked breath. A puff of steam rose from her flared nostrils after an involuntary snort. Her skull crunched as it reshaped. Her jaw extended, bring her mouth and nose forward into an obviously equine snout.

She tried to get up but couldn't. Her body was too deformed and foreign to operate properly, her torso awkwardly long. She went to reach for her phone in the pocket of her destroyed pants but her fingers were hardened, fused together. She kicked her shoes off and her feet looked the same.

Then she felt a tingling by her rear. She became aware of her tail, swishing the cold night air. But that wasn't the only tingle she felt. Her pussy was dripping wet. Waves of arousal washed over her. Her growing anus twitched. Despite the horrific changes happening to her body, all she wanted was to fuck.
