* ''Series/InterviewWithTheVampire2022'': A MMF variant occurs briefly with Louis, Lestat and Lily in the series premiere. Both men are nude while she's topless and is sandwiched between them, but their foreplay doesn't get very far because Lestat activates his vampire skills to make Lily [[ForcedSleep fall asleep]]. After she dozes off, Louis and Lestat continue having sex on their own.

* ''Series/YouMeHer'': Jack, Emma and Izzy decide to have a threesome, though first they do some research on just how it works (they watch some porn but find it unrealistic). They all manage to improvise and have an enjoyable time (before they're [[InterruptedIntimacy interrupted anyway]]), but they resume it soon. After this they continue having threesomes together.

Also known as a [[EverythingSoundsSexierInFrench "ménage-à-trois"]][[note]]Note that "ménage à trois" does not actually mean "threesome" in French; the literal translation is [[{{Polyamory}} "household of three"]][[/note]] or a "threesome".

The most common forms of sex involve two people. Supposedly it feels pretty good. So what's the most obvious way to take this [[HotterAndSexier steamy]] dynamic and ramp it up? Add another person--preferably a sexy one.

This trope is most commonly used as a form of basic {{Fanservice}}, and -- due to MaleGaze and MostWritersAreMale reasons -- the third person in this scenario is usually a woman, and the important in-focus character is usually a man. Who these women are or why they're willing to get into a threesome is rarely considered important information. Oftentimes, both women won't even have NominalImportance and will exist entirely to show off how manly the guy is for having a threesome. This aspect of the trope is shown in one recurring aspect of the sex act--it will sometimes start out with [[GirlOnGirlIsHot the two women making out for an extended period of time]] before eventually "inviting" the man to join in, conveniently shortly before we FadeToBlack. Naturally, this form is very common in pornography.[[note]]All except the "fading to black" part.[[/note]]

As a narrative tool, most dramatic tension is built in the lead-up to the act, with characters discussing how or why they want to do it. It can also be used to develop sexual tension during the act by having the male character do it with his girlfriend and a third party, only to discover that he kind of likes the third party ''more''. Some audience members will be annoyed that his getting too much sex is supposed to count as a "problem". One common variation that turns the trope into a joke involves a man's girlfriend suggesting to him that they do a three-way, and he quickly and eagerly accepts, only to discover at the last minute that the third party is a dude. This puts him in the [[HilarityEnsues hilarious]] situation of either having a GayMoment or admitting that he was being [[{{hypocrite}} hypocritical]] in only wanting three-way-sex when it fulfilled ''his'' fantasy.

Like any sex-related trope, {{Double Standard}}s apply. If a woman acknowledges to have partaken or to desire the 2 males/1 female variation of this trope, expect people around her to view her with disgust or at least with suspicion because MyGirlIsNotASlut. In real life, the 2M/1F ménage-à-trois is [[http://www.healthyplace.com/sex/psychology-of-sex/womens-top-ten-sexual-fantasies/menu-id-1482/page-2/ just as common a fantasy]] among women as the 2F/1M is among men. And of course, there are also one-gender variants (FFF and MMM) to play around with but they're mostly consigned to the MinorityShowGhetto.

The SuperTrope to TwinThreesomeFantasy. For specific examples of MFF, MFM and MMF variants, see AThreesomeIsHot.[[note]]An MFF threesome is ''of course'', a one man and two woman threesome, either [[GirlOnGirlIsHot with]] or without bisexual contact, an MFM threesome is a two man, one woman threesome without bisexual contact and an MMF threesome is a two man and one woman threesome [[GuyOnGuyIsHot with]] bisexual contact.[[/note]] This is an easy way of raising the stakes in an EverybodyHasLotsOfSex setting. Compare MileHighClub in terms of sexual rubicons that [[AllMenArePerverts all men]] are supposed to aspire to. If one member of the threesome is not participating but just watching, that'll usually involve SexInASharedRoom (although it often doesn't apply in threesomes due to consent issues).

* ''Film/WhereTheTruthLies'': The catalyst for the film's plot is a threesome gone wrong.

* In ''Literature/TheDresdenFiles'' short story ''Backup'', Thomas Raith is talking with his sister Lara over the phone, and it turns out she's apparently calling him [[CoitusUninterruptus while in the middle of a three-way.]] Being [[HornyDevils White Court vampires]], neither of them are perturbed by this.

* In ''WesternAnimation/Castlevania2017, a squicky one with rapey undercurrents happens when Sumi and Taka have Alucard tied up with a magic weapon and the two of them have sex with Alucard, including Alucard being the sub to Taka's dom.

** In "Mort Dinner Rick Andre", Rick's nemesis Mr. Nimbus notices Beth's and Jerry's "sex-positive" vibes and invites them to have a threesome with him. They're cautiously interested, especially when they each think the other really wants to give it a go, but admit to each other in TheStinger after they arrive for it that they were really doing it more for each other than themselves, and decide to head home...only for Mr. Nimbus to let them in and reveal that he's ''quite'' [[BiggerIsBetterInBed well-endowed]], at which point, Jerry and Beth are quite happy to partake.
** In "Bethic Twinstinct", [[spoiler:Earth Beth and Space Beth start an affair behind Jerry's back. When he finds out and later confronts them about it at the end of the episode, he tells them that his biggest issue was really just them keeping it a secret from him (which Earth Beth admits was wrong) and he's okay with it if it makes her happy, which quickly leads to the Beths getting it on right in front of him while he encourages it. This ends up being a big turn-on for all three of them, and while the audience can only hear and not see what happens next, it's heavily implied to turn into a threesome soon after.]]
