My wife has had a group of friends since high school, which was some years ago. One night we were playing "which friend would you" when she brought up that she had sex with one of her friend's husband. This friend and her husband had been together since their sophomore year of high school. But for a few months after high school they had split up for awhile. My wife ran into him at a party with a different group of friends. They of course started talking about her friend. My wife told him that what the friend missed most was the sex with him. He admitted he missed sex with the friend too. From that the flirting started. He admitted he always thought my wife was cute. My wife told me she noticed he was getting hard. In fact he caught her staring at it. My wife wouldn't give many details on how it progressed but she ended up in a bedroom on her knees sucking him. She said she only intended to give him a blowjob but ended up pulling down her pants and bending over so he could fuck her. Judging by how wet she gets when we talk about this she really enjoyed his cock.

They ended up having sex a few more times. I love hearing her talk about sucking him and him eating her and the positions they did it in. It was really a fuckbuddy kind of situation. After a few months he told my wife he was having fun but really wanted to get back with the friend. They decided to have sex one more time. To me this was the kinkiest. They had sex while my wife talked about how nice her friend was and he talked about how much he missed fucking. He came in my wife thinking about her friend and his future wife.
