Our first time. She had been chatting on Facebook with an old boyfriend for a few days. Nothing hot and heavy, but just catching up. She had asked if I had minded if she chatted, given their history as a couple, and I assured her that I did not mind. A few days later, I asked how her chats were going, and she told me that he was getting kind of flirty. I just told her to go with it, have fun. She did, then he kept asking her to meet. She told me everything and I could tell that she was loving the attention. So, during sex, I brought up the threesome fantasy again, this time, I added his name into the mix. She came almost immediately, so I knew this was an interest to her. Afterwards, I mentioned it again, and she was a bit embarrassed, but admitted that she had thought about it. She went on to tell me that they had history and that she would feel comfortable with him. So, I told her to bring up the possibility to him. Three days later, a knock on out door, and her old boyfriend was standing there. Ellen had been drinking wine for the past hour to calm her nerves. I let him in and he and I went to the living room and chatted a bit, getting to know each other. After about 15 minutes, Ellen came in and sat beside of me on the love seat. We continued our conversation for another 15 minutes, then Ellen leaned over, pulled my head in and gave me a deep, hard kiss. Then she whispered, "Do you mind if I go over and set by Rick?" I just smiled and gave her a nod. She stood up and walked over and sat beside of her friend on the couch. We talked a little more as he reached back and put his arm around her shoulders. She finished another glass of wine, then she nervously asked me, "Would you mind if I kissed Rick?" Again, I just smiled and she took the cue. She stood up turned and sat across his lap, she leaned in and gave him a kiss. Then she looked back at me as if I were ok. I smiled, then she turned back around and they started kissing again. They kissed for several minutes, as I simply watched, then he brought his hand off of her shoulder and started rubbing her tits. This continued for several as they made out, like teenagers on a couch. Finally, I walked over, and said, you can get much better access, and I leaned over and took her shirt off. From that moment on, she relaxed. We took turns sucking her tits, kissing her and eating her out. Then she stood and invited him to the spare bedroom where she undressed him and they got into bed. I followed and watched as they kissed some more and reacquainted themselves with the other's body. I watched as she kissed down his chest and took his cock into her mouth. She sucked on him for several minutes, taking him deep, then motioned for me. I walked over to the bed and she took me in her mouth too. From there, he began eating her, until he finally moved up between her legs and stuck his cock into her drenched pussy. I about lost my load right there. So I backed up and thought about anything but what was going on in front of me. It worked. I sat back and watched them Fuck. My beautiful wife with another guys cock slamming into her. My wife, gasping for breath, squealing and moaning, as I knew she was cumming. She reached for my hand after the second orgasm and said, "Your turn." So I got onto the bed and we began to fuck, as he stood beside of the bed and took him again into her mouth. This continued for most of the afternoon. That evening, he added me on Facebook, and thanked me for letting him. He also told me how much she had changed from the time that they dated. Things she did now, that she never did then.
