The bell rings, signaling the end of the class. Everyone in the room is happy to hear it, except Kyle. Instantly, he stiffens again. Knowing that no one will think it strange, he gets out of his chair and starts to walk to his next class on the other side of the school. On the way, he ducks into a restroom and enters a stall to try to take care of his throbbing erection.
Once inside, he pulls down his briefs, and starts to jerk off wildly, thinking about what he just did to both Mark and Jennifer. It doesn't take long before he sprays the walls with his seed, and of course grows another inch.
After he softens, he rushes to get to class before it starts. He enters the room just as the tardy bell rings, causing him to throw another boner. This time, however, he is embarassed to discover that his dick is now so long that it sticks out of the top of the briefs. Even though the class (thanks to Mark's curse) doesn't think it strange that he is wearing only his briefs, they begin to laugh and point at his peeking prick.
Kyle turns around and returns to the now empty hallway, rushing back to the restroom. Once there, he tries to think of anything that he can to make his erection diminish (he even tries Algebra!), but nothing works, and he knows that Jennifer's curse will keep him like this for an hour unless he comes.
