Rob was still trying to center himself after the sudden growth spurt when Scott walked in. Rob was balancing himself with his left hand against the wall, and holding his little penis with his right thumb and pointer finger. The room was just starting to stop spinning, when Scott stood next to him at the trough urinal and opened up his cargo pants. Scott was shorter than Rob was now, but use to be a good 5" taller than him, making him about average height for the guys their age. He had dark blonde hair that he usually dyed a different shade of blue or red. His ears, nose, and nipples were pierced. He and his friends skateboarded in the school parking lot after class got out each day. Usually shirtless trying to attract girls with their slim athletic frames. "Damn ain't karma a bitch" Scott half giggled. Rob looked up at a smiling Scott. "You got big arms, and plenty of muscles, but a teeny tiny pee pee" Scott said, turning the last part into mocking baby talk, "you jocks can work out all you want you'll never have this" Scott heaved out his giant dick, "8 inches soft almost 13 when I'm hard and thick as louisville slugger, your girl wouldn't even feel you slide in after I'm done with her" he laughed as the piss came spraying out of his firehouse dick. Scott finished up and looked at Rob's little penis one last time, "you even start yet?" he teased as he went to was his hands. Rob was angry, he didn't even have to think about what his next change would be, that dick would be his.
Rob watched as his pathetic penis expanded inch after inch in both length and girth. His little balls grew from grapes to orange size in an instant. He was still holding it with his thumb and pointer until it grew to long, heavy and thick and he had to grab it with his entire hand. Now this was more like it. He finally started to pee, the force of his new mighty trunk too him by surprise, the piss came flying out of it. He couldn't wait to see it cum. He stuffed it back in his underwear when he was done, they were really tight at first before they expanded to accommodate his new size. As Rob walked out of the bathroom he considered all the ways he could show off his new tool. As well as put that arrogant skater in his place.
