Our marriage had been pretty good. Or at least that’s what I had thought. We loved each other and our sex life seemed to be pretty hot. We liked to experiment and we always tried new things. I figured she was as satisfied as I was. I had no desires to look for other women to screw behind my wife’s back. And I did not suspect she had any secret lovers either. Until the night the plant had an assembly line problem and I went home four hours early.
