About six months ago I watched my wife have sex with her boss who is twenty years younger than her. She swore to me that in the thirty years we've been married it was the first time she had sex with anyone but me. She is a very attractive 50 year old milf and she told me he had been flirting with her at the office.So I told her to call his bluff never thinking she would go through with it. Two days later I hid in our closet and watched her suck his cock and fuck him like a teenager. She was a total slut and let him cum in her. They are now involved in an affair. She has accompanied him on a few business trips and admitted to having a gang bang with him and two clients. I'm getting a little jealous but our sex life has never been better.
