I got to see a favorite Thur night. My wife was quite horny as she had not been laid in over a week. She hooked up with a friend that she has been with a number of times in the past few years. She invited me along if I wanted to watch but warned me she was really horny and there would be no holding back. She was going to jump his bones and fuck him silly. It turned out that she did not need to jump him. He laid her on the bed, hooked her legs and forced them apart as he knelt between her legs and aimed his cock at her pussy. Took about 3 strokes and he was buried to the hilt and started pounding her deep and hard. At that pace neither could last long and both came pretty close together. I knew from her sounds that she came really good and apparently he did too as I watched his balls contract and pump his sperm deep inside of her.
