@Scott888: Each and every boy, esp. after 13, has practiced masturbation (& ejaculation) in one form or another; the one of this video is actually called humping, I think.

Simply rubbing your stiff cock like that feels SO GOOD. It makes me wonder how ANY boy, at 13 or so, doesn't at least accidentally figure out masturbation and ejaculating, even if they never were to hear about it.
