"I want to be older!" Tom eagerly exclaimed. This request made Jim raise an eyebrow with a bit of a smirk.
"I thought you didn't want something too crazy," Jim responded.
"Uh... well, I meant don't make me grow a third leg or something like that," Tom said as he began taking off his clothes and putting on one of his brother's boxers that had apparently been mixed up in the laundry. "So, can you do that? Don't make me too old, though. Something like 18 would be good."
"Heh, alright. Control Tom's Age!" Jim remembered that it only took about two deep breaths to get himself around 18-years old, however, once he blew those breaths, he was quite disappointed with what he saw when he looked up.
Tom certainly grew into tall man, probably hovering around the 6-foot mark if he had to guess, but that was the end of his compliments. Tom grew up to be quite scrawny with no muscle insight. Perhaps he didn't blow into it enough? Jim blew another half breath, but that didn't really change much at all.
"Aww, that's disappointing..." Tom was sulking, not that Jim could blame him. Especially considering how he ended growing up into a stud while Tom... didn't.
"Hey, don't worry. I'll fix it. Release. Control Tom's muscles." Jim started blowing into the balloon once more, watching as Tom muscles expanding along with the balloon.
Tom's almost concaved chest was the first to change, as it started to inflate like, well, balloons. Jim blew until those pecs looked like they belonged on an athlete.
Next, the changes were traveling across his boney shoulders, broadening, and rounding them in the process. Another breath caused Tom's arm's to inflate. Perfectly softball-sized biceps emerged from nonexistence, his triceps followed suite. His forearms also grew stronger and meatier, ready to look good a short sleeve shirt.
Another breath and Tom's flat stomach thicked to form a strong core. Abs appeared row by row until a strong six-pack emerged.
With a final breath, Tom's legs strengthened into pillars that could hold up his new hunky body.
"Release!" Jim finally said, as Tom immediately started to feel his new hard muscles.
"Wow, I feel so strong. I mean, look at me! Thank you so much, Jim." Tom now started to flex and pose. Jim couldn't help but laugh as it was almost the exact same reaction he had when he used the balloon to get older. Although something was missing in this picture.
"One more change. Control how handsome Tom is." Once more, Jim blew into the balloon, making Tom's face shift. His jawline squared out, and any imperfections he had just disappeared. Tom even grew some stubble before Jim stopped and said, "release" again.
"Whoa, I'm a stud now. Haha! Hey Jim, why don't you become an adult now, and we can sneak out for a night on a town together?"
Well, that sounded like fun to Jim, but was that really what he wanted to do right now?
