Just as Craig 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.
As he was passing, Max noticed Craig's bigger bulge. "Craig, what do you have in your pants?" he asked. Craig looked down and then beamed with pride "Oh that's just my willy! It GREW!"
"No way, they can't grow that fast" Max snorted. Without replying, Craig pulled his pants down and Max could clearly see Craig's foot long penis. He gasped, "how did that happen?". Craig shrugged. "I was just standing in front of the urinal and IT GREW! Ooh, if you do it maybe yours will do it too!". He tugged Max's arm towards the urinal.
Suddenly Craig felt the sensation again. When he pulled down his pants he had triggered the growth again! Both Max and Craig’s mouths dropped open as his cock began to snake longer and longer, growing to 22 inches long! His balls swelled up to the size of softballs!
Now a little jealous, Max wondered if this would work on him too. Hesitantly, he stood in front of the urinal and pulled his basketball shorts down, leaving him in his boxers. At once, his 4 inch cock began to grow longer. Craig and Max watched in awe as behind his boxers, Max's balls swelled from the size of ping pong balls to tennis balls. Max's cock then began to grow longer and thicker. It got so large that eventually it dropped and hung out of one of the legs of his boxers. Curious, Max pulled down his boxers, but he triggered the magic again! Max’s 14 inch cock began to grow longer and swell thicker, until it reached 24 inches. Max groaned as he felt his balls expand to the size of melons.
Eventually the growth subsided and Max pulled up his basketball shorts and there was still a huge bulge. His cock outline was clearly visible to anyone who looked and his balls made him look like he had stuffed a couple of shirts in his shorts.
"Woahhhh Max your willy is so big!" Craig exclaimed. Max shook his head in agreement. Both brothers looked ridiculous with their two foot cocks.
