Peter was looking at himself in the mirror while holding the box in his right hand and the pocketwatch in his left hand. There he had his realization that he does look too young to act the way he did before. Now, with the help of the watch, he will no longer be too young anymore. He dropped the box and examined the watch much deeper.
Like what the instructions behind says, he stated his own name softly, "Peter Kim.". He pressed the knob above and let it reach his age, 15. After it stopped, He pressed it but instead of going up a number, the hand went down to 14. He felt his body shirk a bit, but not a lot. Warily, he twisted the knob and pressed it again. The hand returned to 15. He felt himself grow back to his original size. Satisfied, he pressed it three times. He grew up and shot up in height. His clothes were a little too small for him now. From 5 feet and 4 inches, he grew up to 5 feet and 10 inches. His muscles thickened and a soft dusting of 6 pack was visible on his abdomen. His chest hardened, as well as his arms, thighs and legs. He was completely hairless though, being Korean, except on his crotch that already has a bush of hair which seems to have gone thicker. Speaking of crotch, he did feel like his cock grew too, as well as his balls. He was now 18.
Peter removed every clothes he was wearing to take a good look at his body. He smiled with satisfaction, but he still want to grow more. He picked up the watch again and pressed it a couple more times until it reached 24. He grew much taller, about 6 feet and 4 inches. He grew a feet taller than his original height. His muscles got much leaner and his 6 pack was very pronounced. His jaw was much sharper. His skin, although staying pale and healthy, seems much older as well. His cock was definitely much bigger now, about 7 inches flaccid. He was now much happier with the results.
He wanted to look at himself more when his dad suddenly shouted out his name. He quickly pressed the R button and everything in his room began to change. The things he threw on the floor disappeared. His room looked much neater. The clothes on his bed, which was also changing, transformed themselves into something much appropriate for his age; a plain black tanktop, a boxer,and a denim jeans. He picked them up and wore them right before his dad knock on his door.
"Peter, I'm sorry, man. I never thought you'd get mad..." His dad's voice seemed much softer, unlike before which seemed much commanding and prominent.
The reality seemed to be different now, although Peter do not know anything about the new world he's living in. He clicked the M button for the final change and his head felt fuzzy. Everything then came running into his brain. Every new memories, habits and attitudes. He lost balance and felt to the floor due to the heavy amount of new informations that came into his mind. His face then frowned with the fact that he and his dad, now older brother, Eric was just having an argument about their deceased parents.
"H-Hey, Pete. Are you okay in there?" Eric asked in a much worried voice."
"Y-Yeah." Peter said and heard his new baritone voice for the first time. "I'm fine."
"A-Are you sure?"
"Yeah. I just... I just slipped." He answered. "Don't mind it. It's okay. Just leave me alone for a while." He said.
"Fine..." With that, Eric walked away.
Peter stood up and sat on his new bed. He looked around his new room and said to himself, "Wow."
