I have always been curious about this topic. I have had some real surprises in my sexual history, and I am always curious to know...."Who have you had sex with that no one would believe it really happened?" It can be someone famous, or someone taboo for you, or just someone that there is no way that you should ever have been able to hook up with, but yet you did.
I have slept with college professors, and co-workers and bosses, and even total strangers of course, but the most amazing piece of rear that I have ever entered was the MILF mother of a former girlfriend. The girlfriend and I were pretty much like rabbits, tearing off a piece whenever and where ever you could find a second, and I guess her Mom heard us and had questions.
My girlfriend was out of town one weekend and I went over to mow the lawn or something like that, and her Mom made it clear that the landing strip was open if I wanted to. I was always horny as hell then, she was incredibly hot at about 40 at the time, and we just got busy. We did it 7 times that weekend in every combination imaginable, and never again, but I will certainly never forget those 3 days straight from heaven. In that case, her Mama knew what was best.
