"Nope!" said Cody. Jim tried to grab the balloon but Cody's big muscles were too much for even tall Jim to overcome. Cody laughed. "I'm still stronger than you even if you are 6'4" tall and I'm only 5'8" tall!
Jim backed away. Best to not get Cody mad. He was drunk on his new muscles. But at least he was in a good mood. For now, at least.
Cody lifted the balloon again to his lips, then reconsidered. "Release!" Cody said. Jim breathed a sigh of relief.
"Control Jim's growth of his monster cock and balls!" said Cody. Jim looked up in alarm. "Wait!" said Jim. "Please! I don't want to be a freak!"
"Should have let me have my fun... I was about done with you Jim, now it's still my turn to have even more fun!" Cody blew vigorously into the balloon. Jim's 8 inch flaccid cock and giant lemon sized balls swelled bigger... most particularly, Jim's cock gained an aspect of being bloated and swollen... it was more reddish, and his meat inched down another inch until it was hanging 9 inches flaccid. But that wasn't the end of it. Cody blew into the balloon again. 10 inches flaccid it hung, and swelled up thicker. Jim had an unpleasant sensation as his balls were starting to fill his scrotum!
Cody blew into the balloon again. He was laughing at Jim's upset. He thought it was hysterical. He was overdosed on muscle endorphins from his newly massive muscles and it was making him drunk! Jim almost started to tear up at the rush of overwhelming lust that filled him as his flaccid cock hung down eleven inches completely soft and flaccid, swollen like a giant dark red cucumber!
"Just about there," panted Cody, who was gasping from blowing up the balloon so many times. He took one deep gasping breath and blew into the balloon, which swelled ferociously. Jim's cock swelled and drooped lower and fatter, grotesquely huge and bloated, and then his balls stretched his too- small nut sack and pulled at his groin with increased weight. "release!" said Cody. He was practically drooling over Jim's huge meat. "Control the amount of time Jim's junk stays at least this big!" said Cody. He blew into the balloon, quickly blowing it up. "release!" Cody said in panting laughter and threw the deflated balloon at Jim.
Jim grabbed the balloon. He blew it up. "Control the size of my junk!" he released some air from the balloon and nothing happened. He blew into the balloon, one breath, and his cock swelled to 13" flaccid, and his balls pushed against his scrotum stretching the skin tight so all the veins stood out in sharp relief. "release!" said Jim. "Oh, hell," he said, and sat down.
Cody smiled. "This is fun!"
"How long were you thinking each balloon full would keep me from shrinking?"
"Hmmm.... I guess I was thinking about a couple of weeks! Maybe even a month. I like your big cock and balls, Jim. I love them. I'm sorry I shrank them away earlier!"
