I was sleeping over at a friend’s house when I was twelve, and I woke up in the middle of the night to use the bathroom, and my friend was in his 9yo brothers bedroom giving him a b******. To this day, I never told anybody, and I’m not sure if I should have or not. It’s possible somebody was being blackmailed, or they were being forced by somebody else(their father, or whatever), but they were the only ones there, and they seemed to like it, so I just tried not to over think it.
