Grab yourself a glass a wine -- and maybe a cold glass of water -- because the steamy Season 3 love triangle we’ve all be waiting for will air during episode 5 of “Mistresses. That’s right, Karen (Yunjin Kim) is about partake in a bedroom tango with her married friends Vivian (Sonja Bennett) and Alec (Ed Quinn) during the installment rightfully titled “Threesomes.” And according to reports, the encounter will be so hot, it’ll leave Karen unable to focus the following day during her marriage counseling session.

“Is anyone else… feeling warm?” she asks in a promo video after flashbacks of the sensual night she had with the Adams floods her memory.

But Karen’s scandalous romance with the pair won’t end there! Kim divulged to TV Guide that audiences should anticipate to watch the three-sided relationship unfold throughout the remainder of the third installment.

"Throughout the season, it's really about the love between the two women [and] she's very confused by it," Kim said. "She's someone who's never had an experience with a woman, and not just a woman but also [her husband]. So it's going to get messy and clunky... and it doesn't settle until the very last episode."

And that’s not all the drama fans should expect to witness in episode 5, set to air Thursday. The synopsis for “Threesomes” teases that another new and hot relationship will begin to bud in the upcoming installment as “Blair (Brian White) agrees to go out with April (Rochelle Aytes).” But of course, things between these two can only get complicated considering Blair also happens to be Headmaster of April’s daughter’s school. Not to mention, it seems as though someone else has their sights set on April!

Although love will be in the air -- and the bedroom -- during episode 5, the summary also reveals one couple will experience trouble in paradise: Joss (Jes Macallan) and Harry (Brett Tucker). In episode 4, the duo got into a heated argument regarding the future of their relationship. Joss was angry that Harry was avoiding buying a home together while Harry was irritated that Joss was trying to rush things in order to prove something to Savi (Alyssa Milano), Harry’s ex-wife and her sister.

By the end of the last episode, Joss had attempted to apologize to Harry for the fight. But the apologetic text was deleted by the pesky bartender Niko (Emmanuelle Vaugier) -- and because of that, the duo’s relationship will become seriously strained come episode 5.

“Mistresses” airs Thursday at 9 p.m. EDT on ABC.
