Jim grows up

added by PenLover 4 years ago BM S

After lunch, Jim stood in front of his full body mirror. His body disappointed him a bit, and it annoyed him that he could think of so many things to fix.

They all traced back to testosterone too. Jim wanted a deeper voice, he wanted to be taller, more muscular. The balloon made that possible manually, but not automatically. Jim sighed. That part was left to his balls... which Jim could...

Jim glanced at the balloon. Would making his testicles larger help? He shrugged. Only one way to find out. “Control the size of my balls” Jim said and blew into the balloon.

FWOOOOOF. Jim’s balls inflated rapidly, growing from their previous size of grapes to the size of golf balls. Jim liked the improvement, but it wasn’t near enough for him. He blew again.

FWOOOOOOOOF. Jim’s average cock began to look small next to Jim’s balls. Again, they began to swell up, growing to the size of chicken eggs. They hung lower as well inside of Jim’s ballsack. This pleased Jim, but he still brought the balloon up to his mouth one more time...

FWOOOOOOOOOOF. With one last huge breath, Jim’s balls expanded first to the size of large eggs, then tennis balls, then finally softballs before stopped. Jim couldn’t even hold both of them in his hand at one time. Pulling up his shorts, Jim was pleased to see he now had a large bulge in his pants where his balls were.
