I was staying in a hotel room with my cousin, who is 4 years older than me. At night, I was lying on one of the beds watching TV. She went up to me, put her knee on the bed and casually asked if we were going to have sex. I was confused and said no, she asked if I was sure, and I nodded. She said alright and backed off, and she didn't seem bothered or anything. She didn't bring it up again and I'm having a hard time comprehending that it actually happened.
