Looking around the arcade, Dustin spotted Jake. Jake was a 14 year old who went to the same school, but in a lower grade. Dustin knew this because he often saw people in his grade bully Jake, mostly for the lack of any discernible bulge at the front of anything he wore. At a time where all of Jake's classmates were physically maturing, he had quite literally been left behind. Dustin saw this when he stared at Jake and was able to see through his jeans. Poor Jake had a tiny cock that couldn't be longer than 3 inches. Dustin realized he could help Jake, and so he continued to stare.
At first, it looked like nothing happened. Jake still had no discernible bulge, but Dustin could see through his pants that Jake's cock was growing longer. It passed 5 inches to the average cock size. Jake's balls had also grown to an average size of grapes. But Dustin wasn't done yet, he wanted to make up for all of the bullying Jake had received.
Passing 6 inches, Jake's cock finally reached a point where it could not stay inside of his pants. The front of his jeans began to bulge outward in a small, but gradually growing bubble. Jake mindlessly scratched the front of his jeans, unaware of the protrusion. Jake's balls were now golf-ball sized.
As Jake's cock approached 8 inches, the bubble grew. It began to take an unmistakable shape of a tube, snaking down Jake's left leg. Jake's balls had reached tennis ball size, and were creating two more bulges in his pants. Jake began to feel constricted in his pants, but he was concentrating on his game, so he ignored the feeling.
Dustin kept staring; the sight was too good to miss. Jake's now 10 inch cock snaked almost halfway down his thigh, creating an unmistakable outline in his jeans. Even the large head was visible, flaring out at the tip visibly. Jake's balls created two more growing bulges in his jeans, which were straining under the stretch of the behemoth.
Suddenly, Jake's game ended, and he tried to get up. As he stood up, the combination of pain in his groin and the weight in the front threw him off. He looked down and gawked at the enormous tube of flesh that hung down his thigh. In pain from the constriction (and a little turned on) he waddled past Dustin, who was desperately trying not to laugh.
