"I wish Dustin be in this room and will turn into a 20 years old man too but will remember that us being 20 is normal" Ty uttered as his dick gone hard once more.
Having a thought of his foster brother and him masturbating made him feel aroused, even though he had made him feel bad before.
Just in a second, Dustin, the 13 year old boy, was standing inside Ty's room.
"TY, I SWEAR I-" Dustin called Ty but stopped as he felt a warm sensation around his body.
He started to grow in different ways. Ty wished Dustin to be naked so he wont have to deal with his clothes getting ripped apart. There, Dustin, was standing naked and was getting bigger. He got taller. His adams apple got pushed outwards his neck. His baby-looking face started to get more manlier and much older. He grew a stubble on his upper lip and on his chin. He also started to grow muscles. Unlike before, it was much bigger and defined. His 6 packs have returned. His dick also got longer and bigger. His balls dropped and started producing sperm. Hair sprouted above his dick and under his armpit.
The transformations was done and Dustin's brain was filled with new memorries. Dustin groaned and held his head.
"You alright, dude?" Ty said to Dustin.
"Y-Yeah. Just felt a bit dizzy for some reason" Dustin replied.
Ty secretly wished for Dustin's cock to get hard. And it did.
"Why am I here again?" Asked Dustin.
"Uhh.. You asked me if you want to masturbate with me" Ty answered.
"Oh yeah" Dustin walked closer to Ty and sat beside him.
