We first got into it primarily because the GF and I wanted to view how each of us looked while fucking. Yeah you can film yourself but it is a real thrill for me to see a cock pounding her. She really likes watching me do missionary from behind. She gets so wet just watching my cock go in and out of another woman’s pussy
I never understood “taking one for the team”. I could never enjoy it if my GF was just doing it to please me. In my limited experience this works best if the women handle everything. The rules and the over all plan. Even signaling when the action is going to begin. If both women are into fucking the other guy it should go well. Most guys won’t ever have a problem fucking the other woman. It so much more just a fun act and no emotional drama with guys.
