Simon clicked on 14 years old. He only wanted to age a couple years, he was curious what he would look like as he got a little older, perhaps to the start of high school.
He clicked Start Transformation and the machine gave a popup: Include Enhancements? There were a couple of options below. Intrigued, Simon selected Genital Boost and Height Boost. Then he clicked Start.
Immediately Simon felt a tingle. Looking down, he watched excitedly as his legs seemed to grow out of his pant legs, becoming longer. Simon also noted that they had become hairier. A side effect of growing older, he supposed. Man his legs were really long - oh that's right, the machine had applied a height enhancement. Simon didn't know how tall he would be. Speaking of enhancements... Simon glanced down. Yup, there was an abnormally large bulge at the front of his pants too. Genital boost applied, check.
Standing up, Simon was almost thrown off balance. The room appeared to be smaller, but he knew better. Looking down, Simon's shirt was riding high and exposed several inches of Simon's tan midriff. Similarly, his legs had grown several inches out of his pants. Standing against the wall, Simon saw that his head was close to the doorframe! He guessed he was about 6'5" or so.
