I was found by a couple while I was working in a coffee bar. Let me explain.
I sometimes work and stay in an apartment in Vera Playa, which is a swinging hotspot as well as having a nudist beach nearby. I also work online as a teacher, and I for this I need a reasonable Internet connection for a videocall (there is no Internet in the apartment). So I found a coffee bar which serves good breakfasts and coffee, and they gave me permission to take my laptop there and use their Internet connection at a table in a quiet corner inside (most people sit outside). After I finished work one day and as I was putting my laptop away I was approached by an attractive couple, both younger than me. (By the way it's wrong to assume that everyone who goes to this area is looking to swing or play, there are many families who go with their children and they enjoy nudism). The lady spoke, she asked me if I would let them join me for a coffee. They both looked friendly and had nice smiles (which is important to me). I said, "Of course!" and after asking me what coffee I would like, she dispatched her husband to order them at the bar. She said that they had noticed me from where they had been sitting, but I had to apologise as I had not noticed them. I figured that they wanted to know more about the classes I give, but she asked me if I knew that I was in an area popular with nudists, which I confirmed that I did. She smiled at me and asked me if I also knew that it was popular with swingers, which I also confirmed. She asked me if was also a swinger, to which I replied that I wished I was but that I was single. She said that she loves a threesome with her husband and another man, and asked me if I would be interested in joining them. I said, "I would love to!" like a little boy in a sweet shop with a blank cheque, and she added, "for a coffee!" So we started on a good footing with a laugh, and that was before I spoke to her husband. We spent a long time in the coffee shop as we were at a quiet table, so we could talk openly. It was soon apparent that we were compatible in our likes, it was just a case of getting to know each other a little more. We continued to a bar for lunch for that, and we arranged to get together in their apartment later that evening. We all had a great time, and we met again subsequently.
That was purely a case of being in the right place at the right time.
