What do you think about me kissing my cousin on the lips a few years ago?
Are you serious? What made you want to kiss her?
It was a spur of the moment thing. She gave me a coke and for some reason I felt like I should kiss her for it, and it just happened.
At least you understand that it was a spur of the moment thing. It's possible to be attracted to someone that you shouldn't be but as long as you don't act on that attraction iut should be fine. If it was a one-off thing then I wouldn't stress about it but i recommend that you don't do anything else like that in the future. A relationship like that with a family member is extremely inappropriate.
I won't do anything else. I was confused then but she was really excited about it and wanted to go further.
It's a really good thing you understand that then. If she ever gets the idea that you two could pick up where you left off or something be sure to shut that down immediately. It would be really inappropriate if it happened again.
