After the room was empty except for them, Ty noticed someone else walking towards the locker room. It was Charlie, a short, skinny boy who was very shy and very smart. He had an early dismissal from school, so he was going to get changed. Looking inside, Charlie found the room empty (or so he thought), and headed over to his locker.
Sitting on the bench and taking off his gym shorts, he felt a tingling within his boxers, but he thought it was an erection. He had a 5 inch long softie, but now it was starting to get longer! Shocked, Charlie just stared at the growing tent in his underwear. By now, there was a clear bulge and Charlie's 9 inch cock was still growing! His boxers began to strain as they attempted to cover his growing bulge. Charlie moaned in pleasure as his cock grew fatter and longer still, cramped inside his now-too-tight boxers. Suddenly with a massive RRRRIIIIIIIIIPPPPPPP, they ripped open and Charlie's 15 inch cock fell out and draped down his leg. His balls also had swollen to the size of large apples.
Dismayed and quickly looking around, Charlie pulled up his gym shorts over his cock to hide it. However, it was so long that it hung out of one of the leg holes and was clearly visible. In exasperation, he pulled the head up into his shorts and just crammed it into the front, so that it didn't hang out, but there was an enormous bubble in the front of his shorts. Satisfied, he waddled out of the locker room.
