My wife and I married fairly young, I was 24 and she was 23, but this happened about 4 years into our marriage. It was my 10 year High School Class Reunion. I wasn't initially going to go but thought why not. I was in a place where I thought maybe I could kind of brag a bit about my wife (who was fairly cute and small) as well as about my career thus far.
So we went to my class reunion. It was a semi-formal event, at a nearby hotel's ballroom. We ate, drank, and commiserated with my classmates, some of which had not talked to me in school yet they seemed to not have a problem interacting with me and my wife at this time.
One such person was a guy that I knew in school, and not really, more like knew of, but we never really talked much. He came over and almost reintroduced himself to me, and my wife, he also introduced his wife to us. We did hit it off and spent most of the evening talking and drinking and finally for dinner sitting and eating together. When we parted for the evening, we left each other with our numbers to make sure that we stayed in touch.
Now my wife and I had no kids, neither did this guy and his wife. We lived in a suburban locale and they lived in a more rural area. That said, they were only about 30-45 minutes from where we lived. After the reunion we got together a couple of times, either at our house or us at theirs, at one point they even introduced us to his parents and siblings. This was over a couple years time period where there wasn't anything that really happened, then one afternoon they asked if we wanted to go with them to a strip club that had a couples night, which was girls and guys stripping in the club.
One birthday of mine, we all went to dinner and went back to our place after dinner. I guess at some point the wives must have communicated with one another and put together a plan for both me and the guy. So after dinner we were back at our place, just having some drinks, and my wife went out of the room and called out to his wife. They went into the other room and I heard his wife say something about my birthday gift so I just figured it was something that must have been large or hard to carry and my wife just needed some help.
When they came back into the room (family room) my wife was dressed in some sexy lingerie. His wife wasn't dressed quite as nice, but she didn't have on what she was wearing when she left. This was a HUGE surprise as my wife up to this point was very shy and I never would have expected this with her and in fact was almost shocked she was doing this in front of them. Of course some of this may have been due to some liquid courage as we all had some drinks at this point.
This guy that I knew in high school and I were sitting on dining room chairs, in the living room as we were advised to get in those kinds of chairs. So at this point my wife started to dance sexily and began to give me a lap dance, while my friend's wife was doing the same for him. Now I think they all knew we were getting pretty worked up, especially from the lap dance that we were being given. This was apparently my birthday gift. My wife getting dressed sexily and giving me a lap dance in front of my friend and his wife, while his wife doing the same for him.
Had this been the end, I would have said that was a pretty good birthday gift, but that's not where it ended. After my wife had gotten me worked up, she began to unzip my pants, now my friend and his wife were still there, and his wife was doing the same for him. This was way out of what I thought my wife might do. In no way shape or form had my wife ever done anything like this before, at least not with me.
At this point once our pants were unzipped each wife respectively put their lips around our cocks and began giving us each blowjobs, in front of each other. I had looked over at my former classmate and gave a bit of a smile and nod, he returned the gesture. Before either of us were close the wives had stopped their attention and paused, they looked at each other, and they began kissing each other, rather ravenously. Even some light petting was initiated, although by my classmate's wife, it was reciprocated by my wife. After they stepped back from each other a bit, they each took down their tops. Now my wife had larger breasts than his wife, but one more thing happened when they resumed their attention to us, they swapped spots. His wife was now bent down in front of me and my wife in front of him. His wife really knew what she was doing when it came to giving head, my wife was no slouch either as she was running his cock up between her fabulous tits and his wife had rapped her lips around my cock.
Once again before either of us were close the wives stepped back again, took down the rest of what they were wearing and again were kissing each other. Shortly thereafter came the light petting that had started earlier. This time though a little more in earnest, as his wife began to run her fingers along the outside folds of my wife's pussy. After a short time, my wife returned the favor, running her fingers to the outside of the folds of his wife's pussy. Once again they swapped spots, so my wife was back in front of me, and his in front of him.
At this point each of them lowered themselves onto their respective husbands. My wife slowly riding up and down on my cock, and his wife doing the same on his. Over the next few minutes they increased their speed, I guess my classmate was not used to sitting down for this (nor was I for that matter) but at one point he stood up and entered his wife from behind and they started going in a much faster rhythm. My wife was still riding up and down on me while I was still seated, I then too, got up out of my chair and entered my wife from behind, pumping my cock in and out of her from behind.
