Shortly after my affair with 'D' had finished, I married 'S'. We had been together ten years and still had a pretty good sex life. Neither of us had much experience apart from each other, although a couple of times our parties had got a bit wild. On one occasion, four of 'S's friends can to a dinner party with their husbands and the wine was flowing. By mid evening six of us were naked and fooling around. All six of us ended up in our bed together under the covers, paired up with each other's partners. I was with a girl called Jane who seemed very keen on swinging and guided my cock into her soaking wet pussy. Unfortunately at that moment her husband got cold feet so I only managed a couple of thrusts before he called time on it.

 'S' and I continued together, and if the internet had been a thing then I think we'd have ended up on the swinging scene. As it was we were pretty happy screwing each other and being a little experimental with bondage, spanking, anal etc.

After a few years though things were getting a bit stale. I found out 'S' had been screwing a guy behind my back which wasn't the end of the world, but I wished she'd have talked to me about swinging so we could both enjoy it.

During this time, 'A', a very old schoolfriend of 'S's got in touch with us. She had been one of my best friend's girlfriends when we were at school together, and we regularly went around as a foursome. It turned out that she had just found out her husband was doing the dirty on her and she wanted to reach out to friends from way back. Her husband had cut her off from all her friends (he was a nasty bastard) so it's amazing that she managed to find us.

'A' and I spent a long time talking to each other on the phone. I told her of 'S's infidelity and through that common experience we started to grow close. Shortly after this I discovered that 'S' had started another affair so the time had come for us to split.

Inevitably 'A' and I ended up in bed together. She had a voracious appetite for sex, and I took every advantage of it. 'A' was very keen on riding me cowgirl, which I loved, especially as she enjoyed having two fingers up her arse at the same time. When she came I could feel her anus contracting rhythmically, crushing my fingers which always took me over the edge. We occasionally had anal sex, but she loved it so much in the cunt that it was a rare event.

'A' and I dabbled with bondage and domination games. I would call her 'butterfly' and she would have to call me 'Sir'. Unfortunately I didn't take any photos of our play which is a shame because she looked beautiful tied to the bed blindfolded.

After a while 'A' and I got married, but I couldn't get the buzz of cheating out of my head. The internet explosion started to give perverts like me opportunities that had never existed before, and I was soon chatting to other women who were as dirty as I was!
