After Health Class, Ty wondered if his powers would work on himself. He made the wish that school was over, and mentally wished that one of the office ladies would announce that school had now ended.
After the bell rang, he headed home quickly, without even thinking about Dustin. When he got home, he streaked into the bathroom and slammed the door shut. He proceeded to strip down to nothing but his briefs.
After that, he took a good, long look at himself in the mirror, examining everything before his possible change.
Ty was around 5' 6", 130 pounds, and a pretty average "skinny kid" body.
He then began to grow. He quickly grew from 5' 6" to 5' 9". His legs began to thicken, and hair slowly started to grow around his body, in the usual spots. His legs became muscular, like he played football regularly. His arms went from around 13" to 19". His pecs grew fast, and his petty stomach quickly formed a 4-pack... then a 6-pack... then, finally, a rock-hard, thick, and cut 8-pack. His height continued to increase, from 5' 9" to 6' 7". The newly formed stud now had 21" arms and was super vascular. His ass began to shape and to grow as well, and he saw he had a nice bubble-butt. His feet went from size 10 to size 17, and his shoes burst. To accommodate his new longer form, his body became engrossed in muscles as his skin struggled to keep up with the huge amounts of muscle growing on his body.
After this was done in about 30 seconds, he did a 360 in the mirror. He loved his new form, but felt like something was missing. All of a sudden, he remembered. His manhood.
Before the transformation, his penis was around 4" soft and 6" erect. Pretty normal for a 15 year old. But he soon changed that. His penis began to grow in length and girth. 6" soft, 8" soft, 10" soft, and finally, 12" soft. He examined his hard penis as well, and it was at a lovely 15" long and 9" around.
Suddenly, he heard Dustin walk in the house. "Hello," he asked, "anyone home?"
Ty soon realized what he had done to himself, and wondered how Dustin would react...
