Gabe had bought him some time to figure this out, and he was going to take it. He stuffed the pieces of the broken balloon in his book bag and climbed out of his window. With new body was quite muscular and moving in it was quite a breeze! He landed on the grass and began walking very quickly in the direction of Gabe's house.
Along the way, Jim kept thinking about his new body. He was muscular, hot, and handsome; he looked like a high school senior! But what if he couldn't change back?! What if he was stuck like this! How would he explain the muscles and the body hair to his parents?
He looked down. Yeah, he looked like a high school jock! Especially in his tight athletic gear. He could feel his larger genitals swaying in his athletic shorts, the bulge quite noticeable! That was certainly different, but not like he had a choice. He couldn't have crammed himself into his old underwear. He was almost to Gabe's house when he noticed he was openly scratching his armpit. He stopped and looked. He could feel his fingers scratching through the thick bush of brown pit hair that had grown. This is nuts! He hadn't had a single pit hair, before, but now he had bushes under his arms! He lowered his arm and kept walking, grimacing that he saw the tufts still sticking out from under his newly defined biceps and arms.
He finally got to Gabe's. He was just about to knock on the door when he realized; he looked years and years older than he did before! He wasn't the small boy anymore, not with his muscles, body hair, stubble and deep voice. What if Gabe's parents answered the door?! How would he explain himself!
He decided to climb up the trellis on the side of the house; this was his usual clandestine route of entry on nights he and Gabe wanted to have fun but didn't want to get in trouble. He began to climb, but he was very worried because his new teenage body weighed so much more! The trellis held, and he found it so much easier to climb. He felt and could see his muscle bunch up and pop as he climbed; damn he was strong. It was almost effortless to climb now!
He got to Gabe's second story window. He thought of the broken balloon and his new jock body. He had to fix this and maybe Gabe could help! Jim took a deep breath, not knowing what his friend would do or think, and he knocked on the window...
