I [M] fucked my ex girlfriend and her sister in the same night. [MFF] {Long Story}

Well like the title says. That happened. It happened Saturday night and has taken me a couple of days to really think it over.

Firstly, my ex is in a committed relationship with another guy, they have a house together and everything. Which adds to the guilt I feel about it all.

So it all began at my friends birthday, he was turning 25 so he decided to have a rager, inviting his entire friends list from facebook. I was expecting that my ex would be there as she normally is out of state but must have come home for the holidays. It was very awkward with her as the last time we spoke it wasn’t pleasant but it had been a couple of years since then. (We were together for 4 years prior) Anyways, I tried my best to avoid her, stayed on the beer pong table for as long as I could and ended up getting pretty tipsy. I sat down and she pounced, came over and sat next to me. Started talking about how her life was and asking about mine. At this point I didnt really care so I just talked and it felt good, was natural and felt like old times, even had a few inside nostalgic jokes. Anyways she got up and went to hang with her friends and I went back to hanging with mine.
