So me and my cousin were hanging out. After awhile he started rubbing the insides of my thighs and kissing me. I didn't know what to do so I just kissed him back. We had a really intense make out session and ended it with both of us being half naked. I'm not sure what I should do or if I should do anything. I never knew my cousin liked me? The worst part is that it was at a family birthday party.
