My wife Helen told me in March she'd been having an affair with a guy I didn't know, for over a year. I found out two weeks ago it's the very same man who's been fucking my ass this last six months, at a gay sauna I've secretly been attending, for over four years. I've invited him round next week, telling him my wifes going to be away. He doesn't know I know about them having sex and she certainly doesn't know about my gay life outside of our marriage. It's going to fun watching their faces when he walks into our lounge.
