"You know? We can test it on Nathan." Edgar told his friend.
"The guy in our class?" Rod asked.
"Yeah, you know how vain and conceited he is." Edgar kept saying. "Remember how many times has he bragged about his expensive manicures and designer clothes. If this thing really works, it'll be really fun to watch that effeminate guy becoming a bag of testosterone."
"Great idea. He doesn't live too far from here, it won't be a problem to sneak in his bedroom and place the device." Rod said. "Also, I heard that tomorrow he would be in an audition for a commercial. It'll be fun to watch him in predicament."
According to their plan, Edgar and Rod went to Nathan's home. Fortunately, his room was at ground level, so they could easily go in there. After jumping the fence in the backyard, they noticed that Nathan's window was a little bit open. It was good, cause they placed the Puberthere inside the room in no time and turned it on. Despite they wanted to watch his changes, they knew it would take some time so they returned to Edgar's home to take a rest and return there later before Nathan wakes up.
Nathan was peacefully asleep while the Puberthere was working it's magic on his delicate body. Nathan’s body looked as though it was inflating, as his body stretched and widened his pajamas began to shrink. His arms began to shred his sleeves right off his body and his legs began to shred the bottom of his pants. Nathan’s legs stretched longer as he gained height. Next, his feet grew to large size 14’s.
Nathan seemed to be unaware of his rapidly growing body. After a moment, his body seemed to stop stretching, instead it continued to widen. His chest started to rip open the front of his pajamas shirt exposing a rapidly growing chest. Large pecs began to form and his stomach started to form a large set of abs. While this was occurring, Nathan’s shoulders began to widen and form large muscles that shredded the rest of shirt clean off his large and overgrown torso.
Then some changes began to happen on Nathan’s face. It began to mature and get manlier quickly. His face started to become chiseled and form a nice patch of facial hair along his jawline and face.
Finally, the changes reached his lower half. Nathan’s thighs quickly bursted through the remains of his pants. His legs then started to become thick with muscle to match his size 14 feet. The only thing left to grow was Nathan’s small package. Suddenly Nathan’s barely dropped balls started to push from underneath his underwear. His balls became exposed and inflated to a large size. His dick was the next thing to grow rapidly as it became thick and long to a size of 9 inches.
And with his increased manhood, the levels of testosterone in his body also increased, making him grow body hair on his chest, torso, arms, legs and feet. The hair on his face thickened while the one on his armpits and crotch that he had recently shaved off grew back thicker and messier.
Nathan’s transformation was complete leaving a now peacefully hirsute, large and muscular man sleeping in place of the once effeminate boy. The Puberthere had worked perfectly, but there was only a problem, Edgar and Rod had fallen deeply asleep. So, maybe they won't wake up before Nathan.
