"Well those Senors always seem to have fun. But I also want to have muscles and to be popular." Andrew thought. "I wish I was a strong, older-looking, popular high school student!"
At that moment his body felt strange. His muscles started twitching all over and his body felt itchy. He pulled off his shirt to cool down only to have his pants starting to feel strained. His balls felt crushed inside his briefs and his crotch itched like crazy. He looked down to see the floor getting further away. Soon the seams of his pants started ripping. Andrew began to feel his muscles grow and watched his slightly chubby belly turn into a perfect, flat six-pack. His body started to turn him on and precum started leaking out of his now ten inch erect cock.
The changes slowed down as He reached his new height of 6'4" and his member measuring a total of one foot long erect with tennis ball size balls. As he moved toward the door to check his new body out in the bathroom his clothes ripped from the strain. He walked back to the machine to try and get another wish so he could get clothes.
