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

It is hot, at least for us, to watch each other having sex, like watching a porn were your partner is the protagonist. Also, nobody fucks the same. The way my GF fucks or is fucked by someone else is different than the way we fuck. The same applies to me. It is hot for us seeing each other having sex in a way we don’t usually do. Also, being with someone you’re not normally with is hot for us too. And finally and more important, it is fun. We date other couples and have a really good time. We even have dates with other couples where we don’t even have sex: a normal night out but with the added bonus of flirting without guilt or shame.
My GF and I met several years ago and we always were a horny and playful couple, so we started talking about other people while having sex and started making jokes about having sex with other people really early in the relationship. So we didn’t really had a lot of trouble taking a step towards being swingers. We did threesomes with some friends and everything was ok most of the time so we also dated some couples we know.
Most important thing is, I think, to always tell the truth to your partner and have some sort of rules, but also remember that rules will be modified over time and that both need to be aware of that.
When you start does everyone just get naked or do you play some kind of game that causes the removal or articles of clothing?
Another question - do the guys try to both finish at about the same time?
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.
