# Meeting him
So this might get long, but I’d like to tell the whole story. It happened this summer, I (23) had just started dating my girlfriend (24) 2 months ago and we have always had an open-relationship agreement. Let’s call her B. However, none of us had made a move on any other girl/guy (we are both bisexual). B is pretty active and was always looking for concerts or music festivals all summer, which I really enjoyed. She would talk to me about one specific band, which had heavy sexual and fun lyrics, and how one of them, a guy, was a crush of hers, we would joke with those lyrics a lot. We shall call him H now.
So one night we went to their concert and had an amazing time, really fun concert. We eventually went and talk with H and we found him really really nice, we could also feel some chemistry there. So after that night we both started talking about H. She liked him, I found him cute, and we liked his music. There is one specific song that actually made us pretty horny, to the point that, one time at my house, I started fingering her while it was playing on my phone. We ended up talking about a posibility of a threesome. We were both ok if it finally happened, not necessary with him, but we wanted to try this experience.
