Let me tell you a little about myself, I am an engineer by profession, but my true passion is martial arts. At the time this story occurred, I was in my early 40s. I am very strong and muscular for my age, and most people feel I am much younger than reality, often guessing in the late 20s to early 30s. My wife is two years younger than me, long curly blonde hair, and of average physique. By average, I mean that she was once very tight and toned, with a round butt and nice 36 C breasts. Over the years, childbirth took its toll and she has put on a few pounds. She still looks amazing, but now in a mature way.
It all began at a chance encounter maybe ten years earlier, at one of my belt testings. I was testing for 3rd degree black belt, so my instructor called in a number of guest judges. One of the judges brought in some of his black belt students. I did well and was promoted, but that isn't the important part of this story. One of the visitors was a girl named Tabitha, or Tabby for short. She had just turned 18, was small and petite, and as it turns out, very flexible. After testing was completed, she called me off to the side and showed me a few stretches that she really enjoyed. Wanting to learn more, I was following along. She soon showed me a "partner" stretch which involved me holding onto her strong and tight body. I wouldn't have thought anything more about this encounter except that I noticed that her pussy was drenched and I could feel it though her pants. She was getting close and we were about to kiss, when we were interrupted by one of the other instructors. She lived two hours away and afterwards, with the age difference, we never pursued anything.
Over the next ten years, she married her husband and I married my wife. We met a few more times, but we were always aware of the other's spouses. That is until we met up at our annual nationals. During the weekend of competition, she won her division becoming the adult woman's national champion. I took third place in my division and her husband didn't place. My wife, although also a black belt, decided to just enjoy the vacation, rather than compete. In all, it was a fantastic tournament and we had a lot of good competition.
Afterwards, there is always a huge awards ceremony with an open bar. It is expensive to attend, but it is also considered to be one of the expenses associated with being a part of Nationals. There was a lot of alcohol, and far too many drunk fighters in a small space. I'm not suggesting we all wanted to fight. No often things get too friendly. After all, most fighters are actually friends. My Grand Master was a classic example. Even though he is an American citizen, he is also a Scottish immigrant. So by the time he was overly drunk, he found himself running around in a kilt offering to show everyone what was underneath. He thought he was being funny, but my wife and I decided it was time to leave. She and I were both a little horny, so we switched into our bathing suits and decided to sneak down to the hotel hot tub for some romantic alone time.
When we arrived, we found there was another couple there. We joined them and sat talking for a while. We found they only lived a short drive from the tournament, but decided to stay the night due to the award ceremony. We lived half a country away and we had flown in. We were all drunk and horny, and soon found out this other couple was swingers. Although we knew what swinging was, we didn't really understand how it worked, so we spent a good hour talking to them. This culminated on our wives sitting on the other's lap. It was scary at first, but alcohol really helped things along. My wife has nice breasts, and they are one of my favorite parts of her body, The lady on my lap had watermelons. I spent my time playing with them and her nipples. She was also rocking back and forth on my lap. I was hard as a rock and if my wife would have shown any interest in the other husband, things would have gone a lot further right there. What I didn't realize was things were going a little further on her side, and she was doing everything in her power to not make it obvious she was enjoying herself. When I later talked to her about it, she said it looked like we were having sex on my side, so she followed along. As we very quickly learned, one of the most important elements of swinging, is communication. This was not something she and I had ever talked about, so she was afraid that I might get angry if I saw her enjoy it.
The other couple quickly left to run up to their room and finish with each other. My wife and I finally had some privacy so we began to kiss and touch. Within minutes, we were interrupted by Tabitha. Apparently she and her husband were also on their way out to the hot tub and watched us with the other couple. When they realized we were staying, she sent her husband back to the party to grab us some more drinks. Quickly, we were in a conversation with them and after finishing our drinks, they mentioned they had watched us. We told them we weren't swingers and that just happened because we were drunk, but they said that even drunk they didn't think they could ever do it. We jokingly switched partners and were sitting there talking as another couple came down.
