Married guy, 8 years or so. Two great kids. Went through a rocky patch last year, very close to divorce. Things are a bit better since. Sex is so so, but monotonous. There is a lady friend of mine who was in school with me. So we've known each other a very long time. Plenty times in the past the chats would be "heated". At the height of my marriage problems last year, and after not getting any sex for a while (wife wouldn't even undress in front of me), I visited this lady's house. Didn't know what to expect. Didn't have any game plan. Didn't go there with the idea of cheating on my wife. After a bit of chatting, I did grope her tits a bit. She was aware of my marriage problems so we called the encounter "therapy". She does have awesome tits, I have to say. That was about a year ago. We've chatted many times since. Recently we started chatting and joking about another "therapy" session during which I'd probably fuck her. She says she has wanted to fuck me for a long time. Her husband cheated on her, so she's keen to get back at him.
So yeah, I'm married... but also have a big titted lady very keen for a NSA fuck. What to do??? Will my conscience eat at me?
