I [M] have been thinking in a foursome with my GF and our friends couple [MF] while use a truth of dare app after a drinks night

A couple of friends invited me and my GF to a drinks night with two other couples. Fast forward to when we were already drunk, the other two couples were gone and it was just me, my GF and our couple of friends. There was a sexual conversation before with the other two couple but it didnt move foward, but when there were just the four of us, this conversation came back somehow.

A little background: I have a little cuck fetish and my GF knows and like that, although we never did it. And I have a MFF desire too, but in this one my GF is jealous and says that she dont know if she’s capable of doing and I’m a little ok with this, although I think that someday we can make it (of course I wanted her to like that idea too). In conversations about that we also talked about have sex with another couple in the same room (without contact) and she is ok with this idea cause she has a little exhibitionist kink, so was in that point that out conversation with the other couple became a little hot.
