My wife is a nice looking woman. A good women who happens to be open about sex and who loves sex. Some years ago she accidentally started fucking other men. It wasn't planned, a guy basically seduced her in my presence and with my consent ended up fucking her. She enjoyed the casualness of it and fucked him many more times and slowly we evolved to where she fucks whoever she wants whenever she wants. Sometimes she lets the guys know that I know and that I am good with it. Most often she pretends she is cheating as that seems to work best. Especially with men who get off on being with a married woman. I know when she's horny for some strange cock because she'll dress a little sexier, wear her make-up with a little more precision and will be acting flirty and horny and will do things like drop to a squat in the kitchen and tease me with her mouth.

Recently she stepped into new territory. She and I were supposed to meet my supervisor at his place to go out. I got stuck at work. She went to pick him up alone and she was in that mood. She had know this guy for years and never thought about being with him until she was alone with him. He invited her in for a drink. She was looking very sexy as we had planned to find a guy for her after we dropped my supervisor off but now she was alone with him and feeling horny. She told me later that she lay back on his coach with her drink and really showed off her legs. He certainly noticed. He also noticed when she asked for a second drink then walked around his apartment ending up in his bedroom. She sat on his bed and kicked off her shoes. She said that he was nervous but that he was also hard so she indicated for him to come over. He did. Without a word, she unzipped him, took out his dick and started sucking.

She said that she spent a long time just slowly sucking him then stood up and took off her dress and then he was on her. He took off her bra and panties and sucked her tits, put his dick back in her mouth, ate her pussy, fingered her and fucked her. She said later that once he got going he was a great fuck.

When I met her later I knew right away that they had fucked. She said she was sorry and hopped it wasn't crossing the line. I said it was ok as long as he thinks she was just cheating which she never said anything about one way or the other. She asked if she could fuck him again and I said sure.

They've been having an affair. I know when they are getting together and can always tell how uncomfortable he is on those days because of how he acts around me and how tense he is when the three of us get together. She tells me that when I in the men's room or out of sight she will grab his cock or he rubs her ass or tits. She gave him head once when I had to go to the car to get something. Made him come in minutes. I walked back in and saw her smile and his nervousness and knew something had happened. I know most men would freak if their wife was fucking their boss but I get a kick out of it.
