Chad suddenly felt an odd sensation at the base of his spine. A thin wormy tail grew from his coccyx and he could feel the plastic of the diaper as his new tail slipped through the hole in the back of the diaper. His eyes widened. He bit his lip, and hurried to his desk, and sat down. He worried it might be visible. The tail was the least of the changes that Chad would experience during the hour long class. Fortunately, Ms. Domino had decided that the class would watch a film in the dark. Before she changed the reel on the projector, Chad had discovered that his feet no longer touched the floor beneath his desk, and his arms seemed to have grown longer and thinner. The cuffs on his letterman's jacket only came down to his mid forearms. And his arms seemed a lot hairier. Before the lights came on, Chad had rolled up the bottoms of his jeans a few times. He waited until most of the class had left to stand, and he moved with a slump to conceal his change in stature. He had study hall next period, so he decided to go to the field house early. He figured it was the diaper that was responsible. He probably should have gone to the nurse or the principal or someone in authority, but Chad's thought process was as messed up as his body. He was halfway to the field house when he realized that his had been running on all fours like an animal. He shrugged it off, and continued to run. He had to focus on how to use the key to unlock the door. Eventually, he got it. Inside the dark empty field house. He relaxed. No one could see him here. He tugged at his collar. His body was hirsute now. He only saw fur under his shirt and on his arms. He felt his face, it was just as furry, except for his nose, which was cold and wet.
