A few years ago I worked beside a mature sexy lady, we flirted and were quite friendly until one day we had a quick kiss in a small room. Over the course of the next few weeks we kissed more. we used to meet up at lunch time in the park for some more serious kissing. Then it evolved to serious sexual contact in the car. One time we were having a real good time one summers day in a small country road leading to a farm, she was giving my cock a real good sucking and I was holding back as long as I could when a farm worker passed in a tractor I told her to stop but she continued whilst he passed and he got a good eyeful. she said she would like to have been getting fucked while he was passing and watching, that really turned me on. this got me thinking of how much I would like to see my wife fucking a stranger any takers out there. By the way there are many more spisodes of me and my work colleague that lasted for years
