Ty didn't want to sleep now, not when he could have so much fun. So he got out of bed, dressed only in his boxers. He looked at himself in the mirror.
He was okay looking, he supposed, but he wanted to be more than okay. So, Ty thought really hard and as he got really hard he started changing.
He felt his body shoot up to past six feet. His other parts adjusted accordingly. Ty's skin rippled as he felt himself becoming more muscular. He gained a clearly defined six-pack and a huge muscular chest with some cute chest hair sprouting. His biceps were swelling.
That wasn't the only thing swelling. Ty looked down and saw his once fifteen-year-old cock grow to be huge. But it wasn't big enough, he wanted a monster. His shaft grew to an enormous twenty inches long and three inches wide. His balls were the size of grapefruit. Luscious pubic hair covered them.
Ty grinned. His fun wasn't over for tonight.
