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.
Yeah, that was a good roast, a real top-notch roast. You could see that the dark-haired slut was fucking in the bathroom, and she didn't care who she gave it to or what hole she took it in, as long as she got cum on her tits. Such a hot chick needs three cocks at once, then for sure the nymphomaniac will get a strong orgasm. If you marry such whores, you'll be horny all your life.
Nice, nice, nice.
