My best/worst nightmare

In my worst/best nightmare, I get a letter from my wife of 10 years telling me that she has been servicing her gynecologist on a regular basis for the whole of our marriage. The letter decribes in detail what they do during her monthly appointments. He is retired, so no nurse or receptionist, and no gloves. The visits last for 2 hours and she is nude the entire time. He examines her body in complete, total detail, feels her up all over, masturbates her, takes sordid urine samples, and of course fucks her to orgasm. He is older than me and a real sleaze, but somehow my wife gets off on his doctor/man image.

After I read this letter my wife makes me promise to go along on the next visits to fully understand her need for this obscene relationship with a retired older male doctor. I end up being told to assist him with his examination of my wife. He shows me how to 'properly' fuck my wife, how to 'correctly' suck her off, how to properly present a dick to her mouth for sucking off. He tells me he needs to train me to properly sexually arouse and satisfy my own wife, and proceeds to do so at his leisure.

Who can explain these things?

Want to know how she pays him for these visits?
