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.
As I continued to enter my wife from behind, looking over at my classmate from time to time with a smile on our faces I was able to reach out as he nodded to me, and I smacked his wife's ass while he was picking up his pace. I looked over again and nodded to him in the direction of my wife's ass, and he smacked her ass as well. We continued on for a few more minutes before I erupted inside my wife, a short time later he finished in his as well.
Once we had finished he and I sat back down while his wife and mine went to the other room to 'clean up'. They came back out a little while later having put on some clothing, we had put our shorts back on, they all wished me a happy birthday and they began getting ready to leave for the evening.
Over the next several weeks I would contact my classmate and see how things were going, he'd invite us out to their house and on several occasions it was during a family barbeque or get together but other times it was just my wife and I and he and his wife. We'd have a few drinks and even flirted across our marriages (I with his wife, he with mine). One of these occasions we once again invited them to our house for an evening of drinks and dinner. After we ate and had a couple of drinks in us, we once again flirted across our marriages (he with my wife, and I with his). We then returned our affections for our respective wives. At this point my wife had a bit more to drink than I had thought, and she was starting to get a little on the frisky side. We began to kiss and feel each other up a bit while they were still on the other side of the couch. This eventually led me to go under her shirt and start my attention to her nipples and she got so turned on that she eventually reached inside my pants and started playing with my cock. All this happened while they (the other couple) were still on the other side of the couch. I looked over at my classmate and he was trying to do the same with his wife, but she was not having it. So he was becoming increasingly frustrated watching us with no attention to him from his wife.
Eventually my wife was so turned on that he had made the suggestion that we move to the floor so he could watch us a bit more. My wife had never been an exhibitionist but she seemed at least somewhat comfortable with this, as I continued my attentions to her nipples and now inside her pants on her pussy, running my fingers up and down her slit, and putting a finger inside her occasionally, she was getting really hot and bothered with this. Not sure if it was because of what I was doing, or if it was because we were being watched, or perhaps, a bit of both.
Now that we were on the floor In had unbuttoned her top button on her jeans, and had unzipped them a bit, this not only allowed me easier access to her pussy that was now getting wetter by the minute, but also presented for the first time at least the top of her pelvic area to our audience. This also increased the excitement that my classmate who was intently watching us was feeling. He turned to his wife and she was still having none of it, almost to the point of turning him away.
