Ryan's Dad started to see chest hair sprout from Ryan's button down shirt, and his dad started getting suspicious.
Ryan runs to the bathroom.
As Ryan is running to the bathroom, he hears his dad say "Our Little boy is growing up so fast, did you see that chest hair sprouting from his shirt." Ryan decided to stop running to the bathroom and go to his room, to jack off too his new forming body, Heck he may even like being an adult, especially his Dad.
