As soon as Taylor slid the jersey on, he felt a shiver run though his body. He couldn't explain it.
Jeff decided that if this kid wanted to wear the jersey and the team was short a QB, why not give them a new one? Jeff focused on making Taylor here QB material.
Taylor felt funny all of a sudden, achy and warm all over. His shoes felt tighter and his shorts were all of a sudden giving him a wedgie! He managed to pry his shoes and shorts off standing in nothing but his briefs and the jersey. His feet were bigger, no doubt about it, he also realized he was able to see the top shelf of the lockers! He was growing!
Taylor's arms and legs had stretched out, and his torso had stretched too so now the jersey was up over his belly button. He had no idea how tall he was, but he guessed he was easily a foot taller if not more.
The dull achy pain throbbed again, but instead of his bones this time, it pulsated in his muscles. Taylor watched as his calves swelled out, becoming beautiful diamonds and then his quads expanded becoming thick and powerful. His briefs were straining as he felt his ass grow out becoming thick and muscular. The jersey got even smaller on him as his chest started to balloon outwards and his new 8 pack abs were clearly seen developing since the shirt was too short. Taylors back spread outwards and his shoulders grew wide. Finally his arms beefed up and Taylor could feel how strong he had become as his brain became flooded with knowledge of football.
Jeff decided to have just a little more fun too. He made it so Taylor would only remove him when absolutely necessary, he changed him from straight to gay, and he laughed to himself as he left Taylor with one more gift.
Taylor was trying to figure out why he thought of himself as so unbelievably hot when he felt the tingle in his crotch, his eyes went wide and he ripped off the straining briefs to watch his kiddie sized balls begin to inflate until they were the size of lemons. He could hardly believe it! It wasn't done however, he then watched his pitiful 4 inch hard dick began to swell. It expanded longer and thicker until he was 10 inches long and about 8 inches around. Taylor had become a real man, and Jeff arranged it so that everyone would believe Taylor was starting his 2nd attempt at senior year.
Taylor suddenly forgot about his old life, realized he was late for practice and scrambled around looking for the rest of his practice uniform...
