I've had all sorts of experiences in my life, including at the cinema with my friend. But of course we did not undress. So my friend bent over and sucked me off, then climbed on top of me and jumped on my dick. That's even the neighbors in the hall have stood, but as in this video - never happened! Unless you can find a movie theater with an almost empty auditorium, and that's not so easy! It's easier to run into a cheap hotel for an hour!
Watching your wife suck other people's dicks is a buzz kill. And she understands that by licking other people's testicles, her husband's boner will get sharper. So these swinger couples swap to sharpen their senses, bring back the novelty, and make their orgasms brighter. Only I would make the lighting not so bright, then there would be more understatement and less embarrassment.
Marital sex just needs to be varied. If the couple won't do it together, then clearly they will still do it secretly each separately! I think this home variation is acceptable, in any case it is not as extraordinary as entertaining a large group of swingers. My wife and I once invited me to one of these, against her this clip is just sex puritanical family!
And who jerked off?
