One night I was out drinking with a bunch of workmates. There was a girl there who I had had an eye on for a while and I could tell she also liked me, but we were both married. Anyway, getting late in the evening, because we were young and poor, a small group of us went back to the office to raid the last few drinks from the beer fridge there. My friend was there and we were both secretly hoping that everyone else would head home and leave us alone. First there were six of us, then five, then four, three, and finally just the two of us. After our last colleague left, we didn't say a word to each other, just started kissing. We kissed for ages, then I started touching her breasts. She was getting hotter and hotter. The top came off, then the jeans. I rubbed her pussy for ages through her panties as we continued kissing. Finally, I laid her down on the Boardroom floor and went down on her. It didn't take long for her to come, moaning with ecstasy which made me even more horny. At that stage we were worried that the nighttime security guard might make his rounds and find us, so we moved to my office. She sat me on the desk and gave me the best blowjob I have ever had. We never did fuck that night, but we kept kissing, licking and fingering each other for hours until it started getting light.
