I (M) was looking at some of the Reedit stories about relationships and saw one on a MMF threesome. I was intrigued by the thought of all members interacting with each other. There was a spectrum of reactions in both the male and female comments on the MM aspect. I wondered how I would react IRL, it always seemed that any interactions would be fun, and how could you expect your SO (F) to do anything you would not do. This was on my mind but my SO was not interested. When the relationship ended (for other reasons) I responded to a MM posting from another bi-curious guy and after a few emails we met. We were nervous at first, and things did not finish up completely. About a week later we ended up giving it another try and knew I had to go first or I might not go through with it again. So he lay back on the bed and I began. As he got more into it and began to move in time I found that I liked knowing I was making him move. I could feel it and when it happened I kept at it a while figuring that would make it better. By the time we finished, swallowing was not even a question. I noticed I had a quiet satisfaction that it was now inside and becoming part of me. While I have no desire to seek out further encounters, another part of me is glad I did experience it. I was surprised that I have never felt any guilt associated with that adventure. I am glad I now know I would probably go with a MMF if that would ever comes my way.
