I'm certain this will get buried but whatever.

I banged my cousin a couple times without either of us knowing we were related at the time.

A little bit of backstory; My mother was adopted into a rather large Lebanese family. My grandmother had 12 other siblings and there was a lot of bad blood between them. The grandfather of said cousin was a convicted murder serving a life sentence and was apparently a hired gun for some sort of organized Lebanese crime family in the 60's or 70's. We went to a few family reunions when I was very young and I used to hang out with this cousin because she was the only white relative I had outside of my direct family and the only cousin I have that is around the same age as me. We stopped going to these reunions when I was maybe 7 or 8 because there was always a lot of crazy drama going on. Outside of my grandparents, we were never really close with any relatives on my mother's side of the family.

I was in my early twenties and had just got back from living in New York for about 2 years. A couple close friends of mine were telling me about this pass around girl that they had been banging for a little bit. Said girl hung out with us on one drunken night and after some mud wrestling and showers together, we ended up banging a couple times throughout the week. We only knew each other by our first names for that entire week. A friend of mine called me by my last name the last time we hung out and it clicked for her as to who I was. She asked me what my mothers name was, and then asked what her maiden name was. After I told her she got hysterical and wouldn't tell me what the problem was. My dumb ass still didn't figure it out until she told me a couple hours later that she was my cousin and we used to hang out at our family reunions when we were younger. It didn't really bother me since she was also adobted by her parents and there was no chance of us being related by blood, but it seemed to really upset her. Haven't seen her around for almost 10 years now, and she has me blocked on every form of social media I can think of.
