By the time third period came, Kyle had thought up a plan.
When he sat beside her in class, he leaned over and with a cruel grin said, "Transform or dare." As he said the words, he pulled his long equine cock from his pants. Jen sat the transfixed. She knew she needed to respond but she was too focused on the massive rod just out of reach in order to say anything.
"You get both," Kyle said with a sly smile. "For your transformation, your body will now suffer from a rare and specific STD that is incur able and untreatable. This disease causes a state of near constant arousal and an addiction to horse cum. The disease is only transferable to women and their symptoms will be slightly different. The longer the women go without horse seed, the more equine they will become starting with their genitals. This disease can be transmitted by contact with your vaginal fluids. For your dare, you will transfer the curse back to me. When I fail to respond, you will transform me into a person who no longer needs to wear clothes. Then, you will dare me to fuck you in the back of class but you will specify that nobody will mind."
Kyle waited for the dare to take hold. None of Jennifer's changes would be physically visible but he knew that she had changed by the way she responded to the dare.
"Transform of Dare!" She said quickly. Kyle for your transformation you will be naked and will not require clothes in order to be physically comfortable or to fit in socially. For your dare I dare you to fuck me in the back of class and that people will notice and watch but that nobody would think its out if the ordinary."
Kyle was happy to hear that she had made some minor alterations to the dare but only in a way that would increase the arousal for a slut who wanted attention.
As Kyle stood up, he noticed that his clothes had already disappeared. He pulled off Jen's panties and say her on a desk in the back of class. She hit the desk with a loud squish. Her juices already flowing as a result of her new disorder. Her body needed him inside her and she would do anything within her power to keep him interested in her. She pulled herself hungrily into his thrusts as he worked his impossible long shaft deeper and deeper into her body. The class and the teacher turned around to watch the spectacle. Kyle glanced at the students and saw that some of the guys, especially the basketball players had begun to jerk it to the spectacle that they were witnessing. The girls were trying to be less obvious and were merely pawing at their clothes genitals. Even Mr. Jacobs was boned at the sight of these two sexy teens and their display of animal lust. After a good twenty minutes of horseplay, Kyle was close to cumming. He pulled out and shot his load on the floor next to the desk. Immediately Jennifer hopped off the desk and began to slurp up his horse seed. The effects of her addiction were obvious and soon, Kyle would have a stable of foals ready and willing to do the same thing.
