Thomas reached out and picked up a large wife beater and a huge jockstrap. He was drawn to it because that was exactly what Sean, the big muscular quarterback of his high school football team, always wore. Thomas had changed in the locker room with him enough to know that he always wore the same white tank top and jockstrap under all his clothes. Thomas was sure the ones he was now holding were identical.
Thomas thought about it; "Maybe if I put these on, I will change into Sean!". Thomas became excited at the thought; he had always been jealous of Sean's body. How broad his shoulders were and how big his muscles were, how he would always puff up his hairy chest and stride around the locker room with pride. Not to mention, the pouch of his jock strap that was absolutely stuffed with Sean's huge meat.
Thomas examined the clothing. The jockstrap was quite big and stretched out; it must have held a huge package. There were various stains in the pouch and a few thick curly brown pubic hairs, too. The jockstrap was also stained a bit yellow from sweat. Not to mention, the jockstrap stunk pretty bad. Thomas was grossed out by it, but he knew Sean had pretty bad hygeine; the state of the jockstrap just confirmed Thomas' suspicions it was his.
Thomas held up the white wifebeater and saw it too was stained yellow under the armpits and around the neckline. Thomas took an experimental sniff in one of the stained pits and grimaced; nasty! The tank top smelled like some pretty bad body odor. "Oh well, what's a little BO for the popularity and the perfect body!", he thought to himself.
He purchased the clothes and went home.
As soon as he got home, he went to his bathroom and locked the door. He quickly stripped down to nothing. He examined his sad, under developed body in the mirror. "Hopefully this will be the last time seeing this puny body!", he said.
He stepped into the jockstrap first and pulled it up, he noticed it was very loose on him, and the crotch pouch was huge on him! whoever had this before was realy hung! He felt a tingle in his groin, as his crotch mixed with all the old dried fluids and pubic hairs of it's previous owner. Then, he put on the sweaty wife beater. It was huge on him, like the jockstrap.
Just then, Thomas' whole body felt hot and tingly, like an electric shock. His muscles started to ache, and he groaned. Then, the feeling concentrated on his crotch. The pain subsided, leaving a pleasant heat and a not so pleasant itching sensation. He scratched his groin through the jockstrap. He felt himself getting hard in the smelly material. It felt incredible. Thomas closed his eyes and savored the sensation.
After a few seconds, Thomas opened his eyes, confused; it still felt like he was getting harder and harder, but he should be fully hard by now! He looked down and saw the outline of his cock in the jockstrap. His eyes went huge! He was only about half hard, but he was at least 7 inches long! And, it was getting pretty thick too! Before this, he had only been 4 inches, hard. He cupped his balls through the fabric with one hand and furiously scratched his groin with the other. He felt that his balls were much bigger too.
Thomas felt incredibly horny, but he was distracted by how itchy it was down there. He opened the waistband of the jockstrap to see and was shocked to see a messy thick bush of brown pubes spill out. "What?!", he yelled in surprise. He saw he had a huge tuft of pubic hair now, and he could see that it was visibly getting longer and thicker, curling together and getting darker. He scratched the thick hairs in disbelief. He also saw his huge cock sticking out of the bush and gasped; it was huge, and it was getting bigger it seemed.
As Thomas was busy watching his groin, he didn't notice that he was scratching his chest or his armpits absentmindedly with his other hand. He also didn't notice his muscles start to heat up as well.
