My wife and I had an agreement that while we were in the swing lifestyle that we were same room swap with couples until we knew them very well. We went to a swingers party and I was in the hot tub with others and my wife was on the patio talking to couples and guys. I got out of the tub to go use the bathroom. When I came back she was gone. I went looking for her and found her in a bedroom, naked except for her cum fuck me boots, on her back legs spread and high in the air as Jaren was pounding her pussy. His wife did come in and saw them and I started to get undressed figuring we were going to fuck, but NO she said "lets just let them have some fun" and we went and sat in the livingroom just outside the bedroom. The door was open and we listened to my wife as she had a couple orgasms. She is a little loud when she orgasms. People were walking by and would stand in the door way and watch them for a bit. Well this was the same guy that she snuck off with once before during a swingers boating event. This situation turned me on some, but I was still pissed that she had not followed the rules and again and it was with Jaren again. She later told me that he convinced her that me and Jess went to fuck so she figured it was ok. Fucking fake couple that use unsuspecting newbies so he can get laid. I talked to a few other couples about them and found that there were a few more couple that were in the same situation in the past. He fucked their wives , but the husband never fucked Jess. This is the dress she was wearing that night. The dress was off except for the boots. I took a video of her trying on the dress and CFM boots. I like to post pics along with the story if possible.
Sad, but we have been in this exact position on several occasions. It was not that I would not have let my wife go off to have sex with a guy alone if that is what she wanted but the fact they tricked us into it. We are pretty much into everything but prefer full honesty. We hope things like this do not happen often for you and your wife. BTW, your wife is super hot!
