Watch: Trailer Drops for Polyamorous Reality Show 'Couple to Throuple'

Peacock's new reality series does dating shows like Netflix's "The Ultimatum - Queer Love" one better – literally – as couples flirt with the possibility of expanding their circle of love.

"Couple to Throuple" lets four couples – one of them a same-sex pair – grab the tantalizing possibilities of polyamory by the horns. But watch out! The sharp stab of jealousy is an ever-present likelihood.

Co-host Scott Evans ("Access Hollywood") narrates the new trailer with, "If you were given the chance at non-monogamy in paradise, what would you do?"

Today revealed who the four couples are, with the gay guys being Ashmal Ali, a 27-year-old native of Chicago, and Rehman Bhatti, 31, who hails from Detroit.

The other couples are Sean Williams, 30, and Brittne Babe, 28, both from Los Angeles; Corey Potter, 29, from Great Barrington, Massachusetts, and Wilder Bunke, 30, from Los Angeles; and married couple Dylan and Lauren Bair, 32 and 29 respectively and both hailing from Fountain Hills, Arizona.

At first, the four couples seem enthusiastic about the chance to meet someone hot and compatible from a pool of "fourteen open-minded singles," as Evans explains it.

"I'm bisexual, and he's more of a 'don't knock it til you try'-sexual," Rehman tells the camera. Ashmal, grinning, laughs, "Yeah!"

The straight couples express curiosity and eagerness. "It's kind of like our first time dating as a couple," Bunke says, as Potter looks on. Soon after, Potter makes a proposition to an unseen woman, saying, "Will you be my girlfriend?"

At another juncture, Dylan – bearded, bulked up with muscle, and grinning ear to ear – exclaims, "Let's go!" as he fist-bumps his wife. But it's not long before Lauren tells him that the woman they hung out with the night before had more of a connection with her than with him.

Brief clips show steamy action unfolding between the sheets, some of it with more than two participants.

"Can we get some lube, lube, lube?" Rehman and Ashmal wonder, Ashmal clad in nothing but a Speedo. The moment leaves viewers to wonder with whom they intend to use it all.

"I've never been on a date with three people," Williams tells the camera, his arm around Babe. "You know what I'm saying?"

But he's probably going to have the chance for that, and more; the beds, Evans tells the camera, are "big enough for three!"

Moreover, Evans notes, the would-be throuples "will be helped along by an expert" – namely, "sex and relationship expert Shamyra Howard," Variety detailed.

"Howard is an award-winning sexologist, licensed clinical social worker and AASECT certified sex therapist who identifies what people are missing from intimacy," Variety added. "She founded On the Green Couch, where she helps people manage sexual issues and create their best relationships."
