Me and a co-worker (teacher) had a sexual relation for years.
I don't know where it came from as she wasn't particulary attractive (and in her eyes neither was I), but there was a mutual, very sexual tension between each other from the moment we met.
I was single at the time, but she was engaged. We started of as normal co-workers, but the flirting started soon enough. Innocent at first, but when we started texting it became quite naughty pretty quick. Not much later we started sending nudes to each other.
After 4 months of flirting and texting I drove her home after a meeting. She was wearing a skirt and I boldly put my hand on her upper leg, raising her skirt a bit higher up. She didn't object. On the contruary! She looked at me, smiled and spreaded her legs a bit. I didn't need any more encouragement and felt her up till her panties. In the meantime her hand was over my crotch, rubbing up and down my erection. I parked my car in a dead-end street and we ended up fucking in my car. The sex wasn't good (cramped, uncomfortable and quick) but unforgettable.
For her it was the first time that she cheated in a relation, and she wasn't overly bothered by it. She wasn't looking for new relation, and neither was I. Of course we liked each other a lot, but we both knew a "normal" relation wasn't for us. We only had a sexual attraction toward each other.
For a year we had sex at least once a month (in hotels, much better then cars) And then her wedding came up. She didn't want to cheat while being married, so 2 days before her wedding we had sex for the last time. That was the plan....
The wedding was nice. I finaly met her fiancee/husband. A nice guy it seemed to me. For him I was just another co-worker of his (now) wife.
After her marriage we were "sober" for about 6 months. By that time the itching "down there" had begun again (with both of us) and after a night out with collegues I walked her home. Aided by some alcohol we kissed and felt each other up, and we ended up fucking against the wall in a small, dark alley very close to her home. And after that night it was back to sex in hotels at least once a month. Even after I got into a relationship with my now wife.
It ended some 8 years ago when he took a job on the other side of the country. We kept in touch though, so who knows what the future brings
