Jim was really upset by the change. He knew that he could change himself back by transferring his power to another balloon, but he was really unhappy to have gone from below average to a 13" monster cock to nothing between his legs in just a few moments!
"CODY!" said Jim. "This is really uncool."
"Awww Jim I didn't mean to upset you. I'll fix it for you now," said Cody, slightly chastised. He really did look sorry in spite of his wrestler physique.
"Control Jim's junk!," said Cody, using the modern slang from the local kids. He took a big breath with his expanded muscular chest and blew steadily and slowly into the balloon. The balloon started to expand, and as it did, Jim's genitals reappeared, blowing up with the size of the expanding balloon. Cody's eyes kept flashing back to the balloon as it expanded, then back to Jim's package as it likewise expanded.
In just a few moments, Jim's package had returned to it's normal size. Jim breathed a sigh of relief. Even his small package was better than the breeze blowing between his legs!
"Thanks Cody," said Jim, reaching out for the balloon.
Cody shook his head, and took a step back. He took another breath and blew steadily into the balloon, which by now was about halfway inflated.
Jim felt an odd tugging at his cock. He realized it was because his cock was growing bigger and therefore heavier! Jim looked down in amazement as his cock and balls inflated with size and weight. In a moment, Jim's now erect cock was growing past 6 inches in length. Jim now had a bigger than average cock especially for a young teen. Jim reached out again for the balloon but Cody shook his head again and blew quickly into the balloon, which now was almost full sized. In just a few seconds Jim's cock grew bigger and bigger, until it was over 8" in length. His balls were now bigger than the biggest that Jim had seen in the locker room, even the biggest linebacker on the football team!
"Ha ha!" said Jim. "That's more than enough!" But Cody continued to blow into the balloon until it was bigger than before and Jim felt a sudden increase in his junk as his cock lengthened and then hung lower due to it's increased weight and size! Now his cock was 6 times the mass and volume he'd had when he was hung 5". As he swelled past 10" he certainly felt hornier too.
Jim realized that Cody must think having a bigger dick meant you were more sexual, and as Cody increased Jim's genitals he was also increasing Jim's libido!
"ohhhh man!!!" Jim moaned and stroked his huge genitals. Cody startled to giggle and almost let go of the balloon, but stopped himself just in time. He gasped, "release!". and let the balloon deflate.
"There Jim!" Cody said. "That should more than make up for the joke!"
Jim gasped in amazement. He looked in the mirror and saw himself, now 5'7" tall and hung with over eleven inches. To make things even more unmanageable, Jim's testicles were now hanging in a greatly increased scrotum halfway down his thighs, with testicles inside each one the size of one of Jim's clenched fists.
