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.
Nice couple and they had a good time. Oral caressing in the 69 position is a real hoot. As for me - it is possible to stop here. You don't have to do sexual acrobatics every time. Quite a normal way for two to enjoy sex. But more often in this option, the first to cum is a woman. So then in any comfortable position, you catch up with yourself. It is best to lie on your side - when you come you can leave your dick in the car and lie there for a while more relaxing and stretching your pleasure of having a woman.
Yeah! I hated her grimace! I couldn't masturbate properly.
