I had recently started at a new workplace where mostly women worked. We were 3 men about at least 15 women, many of whom were really nice ladies.
In between them was Yvonne. A lovely, fresh little thing who always had a fresh remark, and she was always ready for a flirt. Yvonne had a nice figure, with small firm breasts, which she often let brush my arms or back during the day, so often that in the end it was hard to believe that it was a coincidence. Each time I could feel how stiff and firm her nipples were. Either she was always hot, or I was very sensitive to her advances.
It wasn't long before I often had to reach over her shoulder to reach something. Each time I pressed my semi-hard cock against her bottom, which she certainly didn't seem to mind. On the contrary, she rudely rotated her ass, so that I lost my breath, and afterwards had to stand with my back to my colleagues until the dick had returned to its normal size again.
It was clear that sooner or later we would have to figure out how to meet outside of working hours if we weren't going to rape each other in public one day, which I was definitely not interested in because there were also others at the workplace that I had a crush on. There were, among many others, a couple of lovely students whom I would also like to get to know better.
The problem with Yvonne was that she was married. Not that it bothered me, but it was a limiting factor. It also meant that I didn't know if she was willing to fully step up and become my mistress.
I got the answer to this one evening after a staff meeting where we finished ahead of schedule. After-wards, there were a few of us who wanted to go out and have a good night beer, so we went into the nearest pub. Yvonne, and I came to sit opposite each other, and soon I felt her foot slide up between my legs, where it finally settled in my crotch. I looked at her and she gave me a questioning look. as I smiled at her, her foot rubbed my rapidly growing cock... A wonderful feeling spread in my nether regions. It was incredibly exciting. I could see that Yvonne had started to get shiny bedroom eyes even before I had started anything myself.
I slipped one foot out of my shoe and brought it up under her skirt where I tried to push my big toe into her pussy.... Yvonne closed her eyes and gasped when I succeeded.
The others looked at her, wondering what was wrong. She replied that she had gotten some beer down the wrong throat and gave way to a violent coughing fit when I started to move my big toe. She moved back on the chair, so my toe slipped out and glared at me with obvious sexual undertones in her gaze.
Soon we had drunk our beers and were about to break up. Yvonne and I managed to get away from the others, and we quickly agreed to take a taxi home to me.
In the taxi, she managed to take revenge for what happened at the pub.
No sooner had the car started moving than her hand crawled into my boxer shorts and took a firm grip around my cock. She pulled the foreskin back with a brutality that made me gasp out loud. She moved her hand back and forth a few more times. She held my cock in an iron grip and although I tried to get away from her brutal attack, I couldn't. I could see the driver looking at me in wonder in the mirror but could do nothing but sink further into the seat and try to look unaffected as Yvonne once again tore back the foreskin. She gave me a look that said, "take that" and smiled sweetly at the driver.
