Jen's friends quickly decided they wanted to see the horses. Jen started to object but her teacher was standing nearby, watching to make sure Jen participated after her earlier display of rebellion.
Jen was dragged away to the horses. Once there, Jen quickly shut her eyes again, in an attempt to stay human. Unfortunatley, Jen stopped walking and Jen's friend ran into herknocking Jen forward. In the commotion, Jen opened her eyes and immediately saw a large black, female horse. Jen was transfixed on the horse as her friends meandered away, leaving Jen alone.
Jen felt an odd sensation in her ears and reached up. Jen felt her ears in a different place. They felt longer and almost like they were covered in fur.
Suddenly, Jen remembered the curse again. She would become a horse!
At that point, Jen's body started to rapdily change. Soldi black fur began to cover Jen's body, starting at her feet. Jen watched in horror as the fur spread up her body. As the fure spread, Jen could feel her clothes getting tighter.
Jen felt a sudden rush of pressure as a tail pushed its way out from the base of her spine. Jen's feet suddenly expanded, causing Jen's sandals to break as her feet formed into hooves. Jen started to cry as her ass expanded and split her skirt and panties, leaving them in shreds on the ground. Now, Jen was forced to lok down and remember the rest of the curse. She would be the opposite gender of whatever animal she saw.
Jen felt pressure build up in her slit as it suddenly smoothed over, leaving her momentarily anatomically incorrect. Jen watched in awe as a lump appeared and suddenly there was a small version of a man's penis where her clit had been before. It suddenly started to grow to a whopping two and a half feet long. As her penis grew, balls formed beneath her penis and dropped down, swelling to the size of grapefruits. A sheath formed around her penis, pulling it up towards Jen's face. Enthralled, Jen took the penis in her mouth and started sucking.
Jen was drawn from her enjoyment as the rest of her body, popped into place, leaving her a fully formed horse. Jen looked around and smelled something. The scent drew her/him to the fence of the horses pasture where the mare was standing. Jen, driven wild by the urges of her curse, jumped the fence and rushed towards the waiting mare.
The mare quickly submitted and Jen rose to a full erection, her monster cock slapping against her stomach. Jen mounted the mare and roughly entered her. After a grueling five minutes that seemed like an eternity, Jen came in the mare. Jen fell back to the ground and passed out as her body reverted to its original form.
