As Ty and Dustin watched, another freshman walked in. The boy looked to be about five and a half feet tall and fairly lean, but athletic as well. He sat down on one of the benches and began to change for sports practice, pulling off his shoes and shirt and pulling on his jersey.
As he pulled his jeans down, the spell immediately began to work. The boy felt a tingling within his briefs. He had a 4 inch long cock, but now it was starting to get longer. As he watched, the bulge in his underwear began to swell larger and larger,
Reaching 8 inches long, his cock started to pull the waistband of his briefs away from him. The boy tried to push his cock down into his briefs but it was so big by now that it just couldn't fit. Almost like a balloon, the bulge in his briefs just kept inflating, past big and monstrous to a ridiculous size for a boy.
Finally, the boy's cock stopped growing at a massive 14 inches long, and his balls had doubled in size to the size of softballs. Almost in a daze the boy pulled up his now-too-tight underwear and winced at the extreme tightness. Quickly deciding against doing this, he pulled off his underwear and let out a sigh of relief.
Of course, taking off his underwear triggered the wish again. Immediately the boy's cock began to swell again like it was being pumped up with air. The boy's eyes nearly popped out of his head as his cock grew to 24 inches long, and his balls swelled again to the size of melons.
Jumping up and hastily pulling on his shoes and basketball shorts, Ty stifled a laugh as best he could as the boy waddled out of the locker room with his cock hanging out of his shorts by several inches.
