In the past few months, I found out that my wife is having an affair. She doesn't know that I know, yet. The guy she is doing it with is an ex of hers and she always commented on his size and how he used to fuck the shit out of her all the time. We have sex all the time. I don't know exactly why she is doing it, but part of me wants her to continue. Our sex life has been on fire the past few..
