To be honest, our first MFM wasn't great. It wasn't bad mind you, but it wasn't great. It was good to break the ice of swinging, and start to figure things out for us. But, it wasn't great. My wife and I had agreed before we dipped our toes in the pool that we would keep at it for a bit, and not base our opinion of swinging on one or a handful of times. We understood that just like vanilla dating, there was going to be a few duds along the way. We might get lucky the first couple of times, and we might not. We connected through SLS, and met up at a swinger club in the region. The second time was with the same guy. I honestly can't remember the details. Again, it was ok but not great. If we'd based our opinions on those two MFMs, there's a fair chance we would be monogamous today. I think we would have concluded, "Fun, but not really our cup of tea" and moved on.
Now the third time....
We met this guy for dinner, and we all really clicked. I'm a veteran, and this guy was still on active duty. My wife has a bit of a thing with guys in uniform. My wife and I have a non-verbal means of communicating when we're deciding on whether to play with someone. Along the way, one of us will squeeze the thigh of the other. The other will squeeze back; one squeeze is yes, two is no. After a while, I squeeze my wife's thigh. I immediately got a very enthusiastic squeeze back, and knew she was really into him as I suspected.
We went back to his hotel room, and things got busy pretty quick. I think my wife was naked in about 5.3 seconds, and us two guys rapidly followed. We spent quite a long time having sex. Primarily, it was the other guy having sex with my wife. I was very happy with that, as my thoughts were that I could have sex with her any other time, but she couldn't have sex with him any time. My wife had an absolute blast. She could not get enough sex from this guy. She loved it all, made absolutely delicious noises while he was fucking her, and probably came a half dozen times. It was toe curling sex for her. One of my favorite memories from that was her on her hands and knees, he was fucking her from behind, and she was giving me head. The combined motion of her being moved by him vigorously fucking her and her moans of ecstasy while I was in her mouth were absolutely delightful.
After we left, and got in the car, my wife said with a huge grin on her face "Ok, now I'm a swinger!" A few days later, she got to have a solo date with him, and once again had an absolute blast. During that solo date, he told my wife that he hadn't been able to cum from oral sex alone in many, many years. My wife took that as a challenge. She is quite talented at giving oral sex, and ...challenge completed
It's 14 years on now, and we continue to play. It's not as often as it used to be, but we still very much enjoy it. The journey continues.
