I pretended not to know a girlfriend was cheating once because the sex was too good.

I’d be lying if I said it didn’t hurt my pride some, but she was the physical embodiment of my dream girl being a very cute, dark skinned, petite, Asian chick with very distinct South Asian facial features, and was into doing anything I had ever fantasized about, and did so enthusiastically including tons of anal with something about anal actually being one of the clues something was up even pointing me towards who it was. I know she suspected I knew something was going on, and think she may have even known I was aware, and was letting it slide because some of the things she’d say and do were kind of like she was telling me.
