Just then, another member of the basketball player waltzed into the locker room. He was skinny, but had just the right amount of muscle tone to be hot. He slipped into a locker row and began to undress. His already large cock and balls were straining his underwear at a whopping 9 inches soft. As he pulled down his shorts, the tingling began. Ty and Dustin were already watching as his underwear grey tighter. His cock began to swell, gaining inches in a matter of minutes. It slowed and eventually stopped, and when he looked down, his underwear was completely full of a warm fleshy python. He decided to let it free, but in pulling down his underwear his cock swelled to a greater 29 inches flaccid, with watermelon sized balls. He was massively hung now, and exhilarated at the sight of it. He pulled on some loose gym shorts, but even those were filled to the brim. His cock and balls were nearly spilling out as he waddled to the exit of the locker room, eager to use his new endowment.
