Just as Ollie was about to walk out his brother Max walked in. Max was a freshman and like his brother he was pretty tall for his age. However he was scrawny and got picked on a lot. Max was desperate to use the bathroom so he didn't notice Ollie's changes as he ran past.
Max pulled down his pants as he reached the urinal and instantly felt a tingling in his crotch. His dick had been only slightly bigger than his brother's at 4 inches, but now is was extending to 14 inches as his balls ballooned up to match. Testrone flooded his body as his muscles bulked up and gained some definition. He shot up a few inches and his feet extended a bit. Realizing the problem if this happened to everyone Ty adjusted the spell on the locker room so that everyone who was affected by it would have their clothes adjust to fit properly in every area except the crotch which would alway show a nice bulge.
Max finished up and went to leave not noticing the changes he went through. He noticed Ollie on his way out though.
"What are you doing here Ollie," Max asked.
"My school has a day off because of a gas leak," Ollie said. "Mom couldn't get a babysitter so she brought me with her to work."
"Well I better get you back to her before she notices you're gone," Max said with a sigh as he guided his little brother back to their mother.
Ty meanwhile was pleased with what had happened so far and couldn't wait to see who would come into the locker room next.
