Questions: Flirting

This happened a few years back when I was 15. It was really weird. He's 8 years older than me. We had always been close buddies, but this kind of crossed a line. He took me to my first party and I got a little silly. When we got back, I wanted to stay up and chat about life. I went and sat on his floor. He somehow got the idea that I was sick apparently? and so he got out of bed and let me sleep there for a while.

A bit later though, he got up and was like hmm cmon, and we went back to the room I was sleeping in and got in bed together. I was really confused. I thought we were just buddies staying up to chat... he eventually started giving me a back rub and then when I kind of faked falling asleep he put his hand on my butt! He also slept with his arm around me. It was really weird. He didn't try to kiss me though, thank goodness.

It was just all around awkward and I was really confused. I was 15 at the time and he was 23. My aunt woke up that night and came up the stairs and started screaming at him because he was in bed with me. The next morning was so awkward.

He and I have never been close since. His brother (my other cousin) said that he might have drunkenly fallen asleep and thought I was one of his gf's. I don't know though... didn't seem like he was asleep. There was definitely a hand on my ass and that was weird. We're related and he's so much older than me! ah, so gross.
