Jim whispered, "Control the size of Ryan's muscles." Then he began to blow into the balloon.
Ryan gasped as he felt his muscles begin to swell. With Jim's first breath, his pecs began to protrude somewhat, his biceps filled up a little, and faint abs appeared.
Another deep breath from Jim caused Ryan to gain a sizable chest and biceps, as well as a six-pack and thicker calves and thighs.
Ryan groaned in pleasure. "Oh, Jim, this just feels so good. Keep going!"
Jim smiled and breathed deeply into the balloon several more times. When he looked up, he was amazed with his handiwork. Ryan was now ripped! His pecs were bigger than watermelons, his biceps were bigger than footballs, his six-pack was now a ten-pack, and his legs were well-shaped.
Meanwhile, the balloon had gotten so inflated that Jim said "Release" and let it deflate.
Ryan flexed his muscles. "Man, look how big I am! Forget soccer, I'm bigger than most of the high school football players!"
Jim then told the balloon, "Control Ryan's age." He started blowing it up until Ryan looked about 17 and huge. Releasing, he then boosted Ryan's sexual attractiveness.
