my cousin just moved to california. my brother's being really nice to her when he usually isnt nice to anyone else. my brother and cousin went out one time and came back pass 4am. and he even invited her to disneyland before his own girlfriend or anyone else. I still didnt suspect anything. however, I know what I did was wrong, but I remembered that I had his password to his facebook and I dropped in on one of their chats. they were talking about "more than kissing", her doing him a "deed", getting drunk together and doing something, mentioning "VS", her doing something on his bday and hoping no one is around, and after they ended their conversation they both said "mwah". I'm I being paranoid or should I be suspicious that their having sex.
btw, she's my first cousin
