I always felt that something was wrong with me. I loved the thought of my wife fucking another man or even multiple men. I wasn't always that way though. I used to get extremely jealous to the point that I would drive off my girlfriends due to my possessiveness and jealousy.
As I got older, I started reading Penthouse Letters. I started off just enjoying any letter that involved fucking, but slowly gravitated towards the wife fucking letters. I guess it was the taboo of it all, seeing one's wife in the throes of passion with another man but knowing her heart belonged to you. Once I realized that as long as my wife's heart belonged to me I didn't have any jealousy then I was fine with the fantasy.
I married my childhood sweetheart, Susan. It wasn't like everyone else though, meeting as children and knowing you would be married. Her father was military and they moved away when she was 10 and I didn't meet up with her again for another 37 years, after I had started my divorce from my then current wife. Susan is very proper and conservative, but she does have a wild side to her. She loves sex and will engage in play with me, most of the times in public places.
Doesn't matter where it is, she will look around and grab me, or rub up against me. I know for a fact that I have her heart and she has mine.
With that in mind, I started thinking about what I would do if someone flirted with her. I thought about how I would react, how she would react, what would happen if things went further.
I started envisioning her rubbing up against another guy, letting him kiss her, letting his hands wander across her body. I then started fantasizing that he was stripping her slowly, all the while I would be there quietly watching the events unfold.
