As Ty watched the water fountain outside, a young boy, probably about 13, walked up to the fountain. He turned it on and bent down, taking big gulps of the water. Standing up, he began to walk away.
Suddenly after a few steps the boy stopped. His stomach made a loud gurgling sound, and he looked down in confusion, wondering what was the issue.
Then the boy felt his cock begin to grow in his underwear. It was only about 3 inches soft but it began to elongate and grow thicker. As the boy watched, the front of his shorts began to bulge out as his dick grew larger, pressing his underwear out more and more. It kept growing, 7 inches long, then 9 inches long, then 11... the boy’s eyes bugged out, when was it going to stop? Finally the growth tapered off and the boy was moaning as his tight underwear was filled to the max with his new 14 inch super cock.
Then the boy’s balls began to expand below his cock. At first they were just ping pong bal sized, but as he watched they grew past the size of tennis balls and finally stopped at the size of large softballs.
The boy now had a ridiculously large bulge at the front of his shorts but he smiled happily and skipped off.
