I fucked the first married woman (Eva) when I was 24 and single. She was living in the neighbourhood. We met while I was making an attempt at gardening as she walked by. Later that day she helped me out with some of that gardening stuff. In the next couple of weeks she helped me a couple of times with my garden. And one day, sometime, somehow we were feeling each other up and ended up having sex. At 43 she was almost twice my age but had a good body with lovely c-cup tits and a great ass. We had sex a couple of times before she put an end to it. Afraid it would come out and she would loose her marriage (and kids)
Too bad. Not just for the sex. But she also had a lovely sense of humour. We did keep in touch tho, but a year later I moved out and never saw her again.
The second one (Linda) was when I was 31-32 and still single. She was my next door neighbour. Not particulary attractive, but not ugly either. Overall a nice and friendly woman. Her husband was a total ass tho.
Because he was such an ass, we didn't have much contact untill she caught me sunbathing nude in my garden. I thought it was secluded. Turned out it there was some sort of gap in the hedges through whitch she could see me. She called me out and we started talking through the hedge. I was still nude, stubbornly refusing to myself not to dress up. Not much later she said that talking through a hedge was silly and that she would come over to my garden. Still being stubborn to myself I kept being nude. We had a nice, non-sexual, chat on nudism and other things of life.
After that day, every time her husband was at work and the sun would shine. I was nude in my garden. Not always, but regulary Linda came over and we just talked and drank coffee. Sometimes I had an erection and she would just glance at it. But one day she asked if those erections were because of her. And always the gentleman I anwsered "yes of course".

Not much later she gave me a blowjob in my garden while I was fingering her. I came in her mouth and she swallowed. We moved on to my bedroom where we fucked until she needed to get home because her husband was due to come home.
Linda was 36, had short brunette curly hair, a bit chubby with b-cup tits. But she would curl your toes with her blowjob skills. She also liked anal from time to time. We had sex many times. Mostly when her husband was at work. But sometimes she came over for a quicky while hubby was watching TV. She often would let him fuck her after we had sex. Apparently he was kinda proud that he could make her so moist and wet...

Eventually they divorced and she moved out. We kept in touch but it watered down in the end.
The third woman I wrote about
here
The last one happened 2 years ago.
My wife and I attended a 25 year wedding anniversay. We met a couple and it just clicked between me and the woman (Suzanne). Suzanne has long blonde hair. She's slim and fit, b/c cup and about 50 years old I guess. My wife and Suzannes' husband weren't quite a match so they soon wandered off in the crowd leaving me and Suzanne just talking and having fun. Later at the dinner table she scooted next to me. My wife wasn't amused by it but sat on the other side of me. Suzanne noticed my wife wasn't happy about her and didn't say much to me during dinner. But she did put her hand on my thigh and moved it up and down towards my groin. While I was afraid my wife would notice the fondling, I got rock hard by it. After dinner Suzanne winked me to follow her and walked away. Fortunately my wife was kept occupied by a past time accaintance. So I could safely sneak out. We managed to find an empty room that wasn't locked. I guess it was some kind of room for the staff since there were only chairs and a table in it. Anyway. Suzanne lifted her skirt and laid back on the table. She unbuttoned her blouse, revealing a lovely laced bra with lovely tits in it. We were both to horny for any fore play (didn't have the time either), so I pulled down her panties and put my cock into her pussy. We fucked for about 5 minutes before I came into her.
Suzanne came as well. Allthough I'm not 100% sure about that.
We dressed up again and I left the room first, going back to the party. While Suzanne went outside and came back some 15 minutes later.
My wife didn't found out and I've never seen Suzanne since.
