This is a true story. It happened sometime around 1985.
It was the wild and crazy 1980's. My wife and I had been married over 7 years and had been together for 4 years prior to that during college. We had no kids yet and had some experience with threesomes and swapping, primarily with college friends.
After graduation, we had met up with several couples through the sex newspapers with spectacular results. We did not have an "Open" marriage per-se, but my wife had entertained several single men during one-night stands when she traveled on business. She would get picked up in the hotel bar.
The first time she talked about her extra-marital encounters I was somewhat stunned for a few minutes, then she described her being seduced in the hotel bar and how he marveled at her incredibly firm, large breasts. She was very inexperienced when we met and always had insecure feelings about her body. She was just 4'11" and had 40 DD breasts. They really were almost freaky. Still are. It really helped her self-confidence to be appreciated by more me than just me.
I realized I was ok with it. I wanted her to feel free to experience whatever turned her on. I was confident in my love with her and my sexual relationship with her. I knew I was a voyeur from our college days and just the thought of her being with another man outside of our marriage really turned me on. She would tell me about how he ate her or fucked her or romanced her; what positions they used, and it would cause us to have explosive sex.
During one of our swinging experiences, I had enjoyed one particularly hot 45-year-old. I was 35 at the time and my wife was 31 but the husband of this sexy little woman was a dud. My wife never even got her pussy licked except by the wife. But that made the experience worth it to my wife and me. She had had minimal interaction with our female college friends, so this was a truly erotic moment for us. My wife loved it.
She also loved it when I ate my new lady friend out and then fucked her in front of her husband. I have about an 8" cock and this lady's husband literally only 4-5 inches so she really enjoyed it.
We also invited a single male friend into our bedroom on numerous occasions during this time. He and I were the same age and very similar builds. He too, had a large cock and my wife thoroughly enjoyed herself with us. There is nothing sexier than seeing your relatively shy wife sink down on to your best friend's cock while giving a shiver and a low moan.
My favorite position was to sit up against the headboard of our bed while my wife was sucking my cock while on her side while she was being fucked from behind by our friend. Her cock-sucking took on a whole other intensity and eroticism and as I shot off in her mouth, she orgasmed, shivering and spasming for several minutes then another as her lover came inside her.
