Had a bad incident with my Brother on vacation, he got a boner from me i think,...

...please help!? We were going on vacation to Florida, and on the way our car broke down so we were forced to spend the night at a motel in the middle of nowhere. Well, my parents were cheap and we got one room, I was forced to share a bed with my 17 year old brother (I'm 21). Well, basically I woke up in the middle of the night because I felt something on my back, didn't think anything of it, until a few hours later I woke up, and he ejaculated on my back. I think he was asleep, but I don't know, how should I handle this, what should I do???

Hmm. Maybe he was just dreaming. lol.
If your a guy [can't tell by the picture] Start a conversation about what get's you hot. Maybe something will comeup.
If your a girl and guy with a great relationship just be lioke. Dude I felt that Boner last night.. Put it away brah. As jokingly as possible.. Maybe he'll give a reason or brush it off. Other then that just don't worry about it. What will telling someone do?
