Hi, last night my sister and I went to a bar to have some drinks. We were pretty tipsy, and the place had live music and a little dance floor, so we were getting pretty handsy with each other there. I really wanted to do more, so I took her into the bathroom, and brought her into one of the stalls. I had her up against the stall, her jeans undone, and I was fingering her while we made out.

I guess I forgot to lock the stall, because a few minutes later a woman opened it and caught us in the act. She was a little shocked at first, but just sort of laughed and said to have fun. We kept on going, and eventually I made her cum. When we got out of the stall there were a few women (probably mid/late 20's) at the sinks, they had big smiles on their faces when they saw us. We all just sort of laughed a bit. I was washing my hands when they asked us if we were a couple or friends. I told them we were sisters and their jaws dropped lol. We left the bathroom, paid our tab and left the bar to go back to my house where we had amazing sex. We wonder if we should have invited any of them over or not, maybe next time :)
