As Ty walked down the hallway, he saw a boy sitting on a bench opposite some lockers. He looked really small and Ty took some pity on him, so he wished himself invisible. Then as he leaned against the wall to watch, he wished that the boy would gain some confidence in a key area...
Luckily, the boy had spread his legs wide while sitting on the bench, giving Ty a perfect view of what was about to happen. The boy was also wearing fairly tight but stretchy shorts. As if on cue, the boy moaned out loud, and Ty was excited. He waited for a visual cue. Just as he thought his wish wasn't working, he spied a small hump in between the boy's legs. As he watched closer, he realized that the small bulge was slowly swelling up. It was working!
The boy continued to focus on his game, seemingly ignoring the tightening of his briefs. Ty had a perfect front row seat. The boy's shorts continued to bulge outwards more and more, slowly expanding. Ty estimated that the boy was now packing the same length soft as he was previously hard, around five and a half inches.
As the bump continued to grow, it started to become more defined. Ty realized that the outline of the growing boy's cock head was starting to be visible in his tight shorts. He watched as the boy's cock pumped up more and more. It passed seven inches now, and the bulge it was creating in his shorts was starting to be ridiculous, but the boy didn't notice.
Ty finally wished for the growth to stop when his cock had passed double digits. The boy just kept playing his game while his massive cock ran down one of his shorts legs. Ty whistled happily and moved on.
