Not exactly a traditional husband/wife cuckold relationship, but close enough for me...
A GF from school days found me on asocial media maybe 10 years or so back. We began conversing and catching up, which led to some light flirting, which led to conversations of a more explicit nature.
Since I was more experienced at video chatting, and she knew enough of the basics to start, so, of course, before long, we are having cybersex.
Then I introduced her to websites comprised of adult video chat rooms, and she lost all control!
We would visit those sites at the same time, often with me 'acting' as a voyeur. She wasn't getting naked (yet), but would show her very ample cleavage in tight tank tops or similar, and I would read the comments that were made in the chat room. It made us both horny, and cybersex afterward was quite intense at times.
It didn't take her long to start showing her tits to guys, then if they would show their cocks to her, she would show her pussy if they jacked off for her.
Soon after, there would be occasions where I would watch her do these things for other guys while we were on cam together (they were *******). That soon graduated to her finding guys that didn't mind having '3-ways' (all of us on cam at same time so everybody could see everybody else).
Over the next year or two, we did so many different combinations of webcam play, and most of it was her cuckolding me. She not only would play with them when I wasn't around, if we were chatting, and one of her 'regulars' messaged her, I had to wait for her to go play with them. When she was finished, she would resume our chat and show me the results; red, swollen and stretched pussy lips, how wet she was in her crotch, and very erect nipples. It was almost like seeing her right after she had been fucked! The only thing missing was a creampie in her pussy.
