[MF] I cheated on my girlfriend but she encouraged it

I was visiting my girlfriend and was looking forward to some mind-blowing sex that weekend. When I arrived at the hotel in her town, she met me in the lobby and told me we couldn’t spend it together because her fiance didn’t leave town as planned.

Clearly bummed out, she told me “not to worry, it would be a fun weekend regardless.” I checked in and we went up to my room so I could change before we went out. We were meeting some of her friends at a local bar. It was a Friday night and everyone was ready to have some fun after a long week. One of my girlfriend’s best friends was flirting with me pretty openly and I felt a little awkward as my girlfriend was sitting right across from me. I was perplexed when she egged me on to flirt with her friend. Ok, so I was a little miffed that I’d come all this way for nothing and I started reciprocating the flirting with her friend. We drank, we danced, we all had a rather fun evening.
