I Play for Both Teams

A woman has a girlfriend and a boyfriend at the same time without them knowing... Based on an anonymous confession on Erika Lust's XConfessions: "When I was in university, I had a boyfriend and a girlfriend at the same time. Neither knew that I was bisexual, or that I was two-timing them. They never suspected that my girlfriend Sara, or my guyfriend Adam were actually my fuckpuppets all along. I loved them both, but they really didn’t see it that way when found out about each other. Oops!" Based on I Play for Both Teams a confession by Ada67
