Sorry for some mistakes, english is not my first language.
We are long time together couple, from an early age together, now in 30s and married. No kids for now.
We have been dirty talking for a long time about possible couples who may join us and swap partners etc...we have built a big wish to try it in real life and didnt know how to start, a bit scared at the beggining ahhh...
Some years passed and we opened an acount on some swing site and clicked with a tourist couple who were visitting our city for few days. We were so hyped when we set a time and date for meeting, it was such a thrill...but they were not swing couple , they were explorers just like us. So no partner swap, just girls kissing and touching but sex on the same bed. Now it seems like vanillish thing maybe, but that was soooo hot at that moment, even now thinking of that gives us goosebumps....they were both so beautiful and classy and hot. Evening passed in a minute, girls kissed and touched, the guy was a bit jelly so he didnt want to move to the next level unfortunately even his girl wanted so much. But thats okay for the first time in my opinion, we had slow and mild first time to examine feelings later.
We then, after that, both agreed we wanna try full swap for sure as we were both so horny months after that first experience.
After 7-8 months we found a cpl also tourists but they were very experienced swingers, which we liked as they can lead the evening and we would follow

We had a nice bar meet, few drinks, awesome talk, flirting a bit...girl had a body to die for and guy was good looking and charming my lady successfully all evening.
We finished in their hotel room and had a great fuck, it was such a thrilling experience to watch my wifey being fucked hard while at the same time i was deep in another pussy....so so hot.
We really had a blast!
Later that evening we gave eachother high five and agreed that we finally did it properly!
No jealousy involved, only pure hot feeling and satisfaction. She said she loved how i looked fucking that guys wife and how she enjoyed some new cock after sooooooooo many years.
Two years passed from that, we both have some online friends who we sext and share hot pics etc etc but no luck finding a decent couple again....but no rush either.
So....months ago, we had some situation and met a woman (fe yrs older than me) and she flirted with me a little, also she knows my wifey too and they are good friends in a way. I flirted back and kept connection with her, texting sometimes, nothing sexual, respectful but on the edge too. My wifey told me she would be okay if i seduce her and fuck her, she trusts me and she sees how that woman makes me horny (we mention her sometimes during sex) and that would be so hot if i fuck her from time to time.
I was shocked, horny, didnt know what to say omg. She was like cmon its okay, dont worry.
Because, i havent mention that earlier, she also knows as i have told her, that for me it would be okay if she has a fuck buddy too...but unfortunately no one on the sight for now

So i bet she wanted to reciprocate things and felt secure and told me that too.
So, now, we are going forward oppening our marriage and become legit Stag and Vixen as we both see eachother enjoy with others and would be so hot to try it and see how it is!
Hope this post isnt confusing, wrote it in a bar, drinking coffee lol
