Dave ran into the change room, still freaking out about his huge eighteen-incher and his equally huge nuts, which were easily ten times the volume they'd been this morning.
Interesting thing about nuts is that they produce testosterone, and with ten times the usual amount coursing through his veins, he was starting to get a woody, and with the size of his meat now, that was something else.
Thankfully, apart from playing basketball, he played football, so grabbed his football jersey out of his locker and put it on over his basketball shirt to try to hide the raging boner going all the way up to the middle of his chest and tenting out the front of his shorts.
He heard the other guys start to come in the back of the locker room, so he dodged out the front, almost running into some buffed out freshman. Ty, was it? Not that Dave was caring at the moment, just holding his huge cock against his chest with one arm, trying to look nonchallant.
Ty just raised an eyebrow, looking amused. "You know," he said, "the more you try to hide, the more it will show."
"Buzz off," Dave said, shoving past him, but as he did, he felt his cock swell up and start to grow, larger and until the head poked out the neck of his football jersey. He rushed to cover it with his hands only to find the head swelling up beyond them and pushing against his left ear. In desperation, he pulled his football shirt up, still leaving the basketball shirt covering the lower part of the shaft and draped the football shirt over the head as it still kept growing, out of the reach of his arms, which were too busy trying to hold up the weight of the shaft.
Finally, a light breeze came by and blew the shirt off the tip, the growth stopping as nothing was hidden, Dave standing their holding his monster cock like a Scotsman holding a particularly immense pink caber.
