When I was younger I started dating my actual brother-in-law, things didn't went very well so we ended our relation and a few months later I started dating his brother. I got married and 2 years later after my husband's birthday party, we got drunk and his brother slept in our house. The three of us started talking about the old days, my previous relation with my brother-in-law and was the sex that we ended up in bed and until now the three of us are sex buddies.
