"Holy crap!" Marcus said as he noticed his new body. "What the hell happened to me... and to you?" After what had just happened, we finally started to relize how much we had changed "It's this shampoo dude. It makes you older when you put it on yourself. I did it and it was the best. We have to go out and find some babes for our new bods" I said. "Or better yet, we can give it to our girlfriends and then they can be our babes" added Marcus. "Damn! You ARE the kid... I mean man with the plan. Let's ty to sneak inside our house and get some clothes on." "Yeah. It'd be pretty weird if hundreds of people saw two naked boys... I mean men walking into young girls' room." We were so not used to our new bodies that we kept saying that we were boys. We left the treehouse and went to Marcus' house. We put his dad's clothes on. They were still a little loose, but we could deal with it for now. But then, someone came across us. It's was Marcus' three year old brother, Sam. "Hey. Who you guys? Daddy!" "Shh! Sammy. It's me Markey." In case you are wandering, Sammy and Markey are pet names for the brothers. To tell you the truth, even at ten years old, that's still kind of cheesy. "Markey? No way!" "Dude, we have to make him understand somehow?" I told Marcus and then a thought came through my mind. "Hey dude? I got a good idea. Why don't we give your brother the shampoo?" "Dude. That would be sick. That way, we could make him understand and make him lose his virginity." So I rushed towards Sam and grabbed him. He seemed to scarred to act and was unable to speak. "Don't worry little bro. This won't hurt at all" Marcus said as he poured the soap onto his head. "Hee, hee. That tickles" Sam said as the changes started to happen. The changes were even faster then both of ours. In about five seconds, Sam's clothes ripped of his body. He was quickly nearing ten as we clearly saw his dick and chest hairs grow out. At twelve years old, the muscles started to form and he grew almost six inches. Puberty hit him like a bat out of hell. His dick grew six inches as well. When he got to sixteen about, the change became drastic. His muscles formed completely and he was already more buff then 21-year-old us. His balls grew hair all around and it grew itself. He then reached 20. His dick hardened and then it erupted. I dodged it just in time and went to get the water. I poured it all over him and he stopped growing at age 21. He was better then us and we started to regret giving him the soap. "Yo Marcus. I'm as old as you now and I am MASSIVE. Thanks a bunch dude."
