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
Honestly there isn’t a ritual or a procedure to follow. It depends on the mood, the place, etc. Sometimes if we go to a hotel with a hit tub in the room we get naked as soon as we enter the room and jump inside. Sometimes we simply dance and tell jokes and start kissing and making out on the bed and the clothes slowly come off. Sometimes the girls make a strip show for us, sometimes we just cuddle together watching a movie. There is no script to follow.
From our own experience I think strip poker or strip trivia are the best ways to get naked the first times you date another couple.
About finishing, honestly I don’t try to. Sometimes it happens (don’t know if the other dude is keeping pace) and sometimes one finishes first, sits on the bed or on a char and enjoys the view or gets some towels for when everybody has finished.
