My brother saw me masturbating?

I was in my room using my vibrator (which was my mistake it's a little loud) when my brother comes into our room for no reason. I was buck naked, vibrator in my vagina, mid-moan. Usually he only comes into our room at nights and he has never done this before. I really don't know what to do? Should I confront him? Should I forget about it? HELP!


P.S. I have heard him doing it before but never saw.
