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.
I recommend such videos to all the guys who want to learn how to do cunnilingus and to please a girl without using your penis (pay attention to the blonde's technique in this video). Who better to learn how to perform oral pleasures than lesbians?) They certainly know what they want to feel and how to achieve it.
