You would think that a married middle-aged guy with a good job wouldn't be crazy, but he was. He hit on my wife by asking her pointblank at his work (my wife installed $$$k business software at the customer's office and then spent a week helping everyone get the hang of it) if she was interested in having an affair with him. She told him no, not at all. In fact, as she recounted what had happened, she laughed at how dumb he was to expect any woman to answer yes. But before she left his workplace, the guy's wife showed up and she was the biggest bitch in the world, which upset my wife so much that she changed her mind. On her last day at his office, she used our reliable invitation: telling him that I had always wanted to see another man making love to her, so would he like to make my favorite fantasy come true. He would.
That weekend he arrived in the afternoon, smelling of Old Spice and nervous. I thanked him profusely for the opportunity to see another fuck my wife. He was a nervous wreck, but he calmed down after downing a stiff drink. My wife left to change into something more comfortable and revealing. We retreated to our bedroom and I pulled the curtains shut and dimmed the lights. She stripped in front of him and helped him undress. Eventually, they were both naked and I got to watch him indulge in our proffered body. He wasn't particularly skilled, but he had a short but really fat cock that my wife liked. In addition, he came several times, which my wife loved. All in all, it was a good time, mostly due to the effusive compliments he paid her, detailing how sexy she was and how he had never seen such lovely breasts before, so we invited him over two more times for threesomes. A big mistake.
He started calling daily wanting to know when he could come over next. When we did invite him over, he wanted to try all sorts of BSMD activities, which we had no interest in. In spite of him being married, he somehow thought that we three could go on vacation together. In general, he became plaintive and whiny and demanding. In other words, we soon figured out why his wife was so nasty.
Then one day he phoned and told us that he has left his wife and kids and he is living in an apartment nearby and that he planned on visiting us all the time now, as in every day. We flipped. We told him to return to his family, as he wasn't going to see my wife anymore; period. He refused; then he started stalking my wife and phoning us all the time. He was convinced that it was entirely my fault, that my wife loved him, and that he could get her to leave me. I had the phone company put a block on his phone, but then he would just use another phone. We falsely thought we were free of him, as we enjoyed a week of peace. We weren't. He began sabotaging the software at his work, so my wife would be sent back to set things straight and he could talk to her again. It was a nightmare. One night, I saw him hiding in the bushes and I chased him for a block. Thank God I didn't catch him or I would have been up on ...... charges. We had a chance to move and we jumped on it just to get away from him. That was it; never again would we play with fire like that.
