From some point in my young adult life, and even before I was married, the idea of a happily married wife enjoying sex with other men has been a huge turn on for me. I know when and how this fantasy began for me but I am still at a loss (intellectually) of how to reconcile this fascination with all that we are taught as being normal.
As a young college student my then girlfriend and I lived next door to an middle-aged couple who were very lower middle class (what can I say? I was a college student) and not at all attractive. But one day the wife stopped by and asked if I wanted any of the huge stack of adult magazines which they were going to otherwise throw out. Now, being a very sexually active and inquisitive young male, how could I let a treasure trove of this magnitude go to waste? So, with my girlfriend's blessing we took in these homeless skin mags and tried to give them a good home.
I was working my way through them, setting aside those of interest and having articles or models which I found particularly stimulating, when I read one article in an old "Hustler". The article was entitled "The Big Suck" and was about a housewife who ended up having sex with a neighbor she encountered in the laundry room of their building. Now this was not shocking, in and of itself, but the fact that she told her husband, who LOVED it and then they arranged for her to fuck him so he could watch was something else entirely!! I was instantly and thoroughly hooked!! The article and the description of his wife sucking and fucking that big dick was an incredible revelation to me!!
I must have read that article five times a day for weeks. I am sure I came more in the next few days than I had up to that point in my life!! When I wasn't jacking off, thinking about it, I was thinking about jacking off, thinking about it. I showed the article to my girlfriend and had her read it. I began sharing this fantasy with her and having her share the fantasy with me. I would have her tell me about the other guys she fucked and how much she liked it; about their cocks and balls and how many times she would cum. We even began to role play where she would either tell me about having sex with some (fantasy) lover or even call me by another name while we made love.
