Just then, a freshman member of the basketball player waltzed into the locker room. He was skinny, but tall. He slipped into a locker row and began to undress. His cock and balls were average at 3 inches soft. As he pulled down his shorts, the tingling began.
As Ty and Dustin watched, his underwear grew tighter. His balls began to swell, pressing the fabric of his white briefs out further. His cock also began to elongate, growing fatter and thicker. When it finally stopped growing, his briefs were straining to hold the boy's massive 13 inch long cock and softball-sized balls.
The boy pulled up his shorts, which barely fit over the huge bulge. Thank goodness they were stretchy! Whistling, the boy walked out of the room with a massive bubble in the front of his shorts like nothing was unusual.
