As Ty walked through the store, he came to the sporting goods section and saw one boy by himself, picking out some stuff for his upcoming baseball tryouts! He was probably 16 or 17, and looked bored as he skimmed the shelf of jock straps. Ty had a funny idea to mess with him though.
Eventually the boy selected a medium sized one and headed back to the change rooms, closely followed by Ty. In the rooms, he pulled down his shorts, leaving him in only his boxers.
This was his chance! Ty quickly wished for the boy’s genitals to start growing, and for it to feel extremely pleasurable. Instantly the boy stopped what he was doing and began to moan, and Ty could see what looked like an erection in his shorts, except he was just growing!
His cock elongated until it was 14 inches long, and Ty finally stopped it there. He allowed his balls to continue growing until they had reached the size of volleyballs. The boy’s underwear was completely destroyed, so Ty wished for his underwear to be repaired with a special XXL pouch to accommodate his large endowment. Dazed and confused, the boy stood with a bulge that looked like he had stuffed a basketball in his underwear. Ty struggled not to smile as he waddled off in his shorts, still seemingly confused.
