Ty sees a teen about his age who has and okay build but Ty decides he could be bigger. The teen feels his biceps start to tighten growing to the size of grapefruits. Then his begins to inflate pushing his shirt outward. Then his abs begin to tighten forming a very well defined six-pack. After that his thighs begin to swell like ballons pulling his pants tight. Ty changes his pants into loose lycra shorts. Ty then expands his calves. Ty enlarges just one more thing. The teen feels a stretching sensation in the skin on his package. His member pushes up his pants. The teen tries to hide it as it continues into his shirt. Then his balls begin to fill up to the size of golf balls. Then baseballs finally the stop at cantelopes. So this teen is standing there increadibly muscled with a large bulge that proceeds up into his shirt.
