1 before we met - first real boyfriend but she made him wear two condoms
2 more other than me after we got married. once with another couple we hooked up with to swing with - having her suck me while I was kneeling beside her and watching him standing at the edge of the bed pounding her pussy was great. His wife had sucked me off just prior...
2nd time was at Hedo III where we hooked up with a couple at the nude pool where we started to both finger each other wives under the water - my wife I think ended up having him stick his dick up her while they were fooling around in the water - a lot of bouncing up and down was going on. We then shared BJs with each others wives.
Later we met up for dinner and proceeded to fuck each others wives on the jetty. again watching her getting pounded from behind while I was fucking his wife was dammed hot - I later watched as she sat on him and rode up and down - watching her cum while his dick stretched her pussy lips apart was really something...
We then did our own wife before calling it a nigh - next day was a repeat - both times bareback and leaving a load :-)
need to do this again - she loves it but then gets guilty despite the fun....
