"Woah look, it's the school's basketball team!" Dustin exclaimed. He had noticed a couple players in the sporting goods store, checking out jockstraps in time for their upcoming season. Dustin recognized them as Jack and Caleb. Jack, the shorter of the two at just over 6 feet, possessed a fairly lithe and muscular build. Caleb was taller but thinner. Both were respectable players on the team, and were dressed in their exercise clothes (shorts and a jersey) as they were on their way to practice afterwards. Dustin decided this was too good of an opportunity to pass up, so he pretended to browse exercise clothes a row behind.
As Caleb walked away, Dustin got his chance. Peeking through the clothes rack, Dustin began to stare at Jack, who was sitting on the bench facing him and reading the packaging material on the jockstraps. Dustin noticed immediate movement through Jack's basketball shorts as his cock suddenly began to thicken and lengthen. Jack moaned softly as his cock began to bulge out the front of the shorts. It was already 3 inches longer than its previous length of 7 inches and it continued to grow, getting harder and harder. Jack's balls also grew from their previous golf ball size to the size of eggs.
Suddenly, Ty's other wish took effect, and Jack's gym shorts suddenly changed into spandex bike shorts. The stretchiness of the material provided a lot of room for Jack's equipment to grow and it took full advantage. Jack's cock was now over a foot long soft, stretching lazily out of his jockstrap and running down one of the legs of his bike shorts. His balls had also grown to the size of softballs. Dustin stopped staring right as the head of Jack's cock grew out of the bottom of the leg, and the growth tapered off.
As the growth lessened, the pleasure wore off and Jack snapped back to reality. Other than his shorts feeling extremely heavy and tight, there didn't seem to be anything wrong. As he stood up, he felt a cold surface on the top of his cock. Looking down and wondering what was wrong, he was mortified to find out that his cock was slipping out of his shorts! He thought that he had found a way to pack it in and keep it supported!
Dustin could see that although Jack was surprised by his cock being so long, he wasn't panicking. In fact, he seemed like he knew what to do to deal with it. Then it him it: Jack must think he had always had a cock this big! Darn it Ty, he thought, this is gonna be so much fun! As he watched, he noticed the system Jack had for dealing with the extremely noticeable bulge. Jack tucked his long cock to the side, where it was comfortably restrained by the bike shorts. Just then Caleb came back.
"Jack, don't waste your time. You know none of those will fit you" Caleb smirked as he leaned against the doorway. Jack sighed. He liked having a big cock, but it was annoying sometimes. "Fine, let's go..." Jack pushed past Caleb and walked out.
