Twin Threesome Fantasy

Beepbeep-boobeep-chirp-weeoo!^Translation"Work those spin cycles!"

"Double your pleasure, double your fun!"

— Long-running Doublemint gum campaign

Bob is attracted to Alice. By some process similar to Oven Logic, he imagines that two Alices must be twice as sexy as one. Sometimes Bob is just fantasizing, but often there's an actual second "Alice" floating around. This may be a genetic twin, a product of Applied Phlebotinum, or more rarely a sibling, parent, cousin, or even just someone unrelated who dresses and acts like Alice.

For whatever reason, a fetish for twins is regarded as G-rated, so characters — especially male ones interested in female twins—can admit to it and not be teased, except for being a general horndog. A woman fantasizing about two attractive male twins however...well, you know.

A less remarked-upon bonus of hooking up with twins is that they make for a wonderfully symmetrical A Lady on Each Arm.

For the record, most real-life twins are as disgusted at the idea of a shared sexual encounter as any other set of siblings, so suggesting a threesome will probably not end well for you. Still, this is by no means limited to porn movies. There certainly are publicly known instances of relationships like these, sometimes initiated by the twins' own volition. And note that while twin threesomes in fiction usually veer toward twincest, the twins can just be interested in the third party, not each other.^note Fridge Brilliance suggests this might actually be the reason for the fantasy. The odd one out gets to have two equally-hot partners, at substantially lower risk of them deciding they like each other better and ditching the Third Wheel. A twin threesome is an inevitable outcome of a non-separated conjoined twin with separate brains marrying a non-conjoined person.

Compare traditional Twincest (just the twins, no third party) and Screw Yourself (with your Doppelgänger, not someone else's). If the twins aren't ok with sharing, you're looking at a Sibling Triangle. Girl on Girl Is Hot is often behind this, and occasionally Guy on Guy Is Hot. Occasionally, the object of lust can invoke this if they have a Doppelgänger Attack-like ability. Subtrope of Three-Way Sex.

Examples:

Advertising

• In this commercial, a group of men get excited at the thought of having Swedish twins come over. The result is not quite what they expected. The ad is for the National Hockey League, and the twins in question are Vancouver Canucks forwards Henrik and Daniel Sedin.
• Doublemint Gum has been advertised by numerous generations of beautiful female twins using the slogan "Double Your Pleasure, Double Your Fun".

Anime & Manga

• In Black Lagoon, Hansel and Gretel make this trope a thing of nightmares. Too bad no-one warned poor Garcia Lovelace. In a omake at the end of vol. 3, they play doctor with him, and if he wasn't traumatized enough, they then play actual doctor with him, reducing the poor kid to bedwetting at night again. Roberta is not pleased.
• In Date A Live, the twins Kaguya and Yuzuru Yamai fought each other at first for Shido's affections, but then agreed they don't mind sharing him with each other. They do, however, mind sharing him with any of the other Spirits.
• The yuri manga Docchi ni Shiro Dotsubo revolves around this. The protagonist Yukino, a school teacher, hooks up with a teenager over a dating app because she reminds her of a student she's smitten with, only to find out that the two are in fact twin sisters. This leads to a threesome betweem them, although from that point on the twins, Runa and Hina, fight over her. By the end, the twins patch up their differences and agree share Yukino, who gladly divorces her husband to start a three-way relationship with them.
• Mairu and Kururi Orihara from Durarara!! invoke this trope. They have no objections to hooking up with the same guy (or girl) and don't see each other as separate people.
• In Full Metal Panic!, the Creepy Twins Xia Yu Fan and Xia Yu Lan in relation to Gauron.
• Futakoi is a Themed Harem show with six separate sets of twins. It literally exists because of this trope.
  • Futakoi Alternative, a successor show with the same girls, but focusing on different characters, and a very different mood, actually played the hero and twin heroines in a more traditional Love Triangle romance. It helps that they shifted the focus onto the one set of twins that were Polar Opposite Twins.
• Irresponsible Captain Tylor has female twins Emi and Yumi Hanner as part of the bridge crew. They simultaneously proposition Tylor for sex. Unfortunately for him, they apparently pick the one time that he's too distracted to say "HELLS YEAH!" and interpret it as a rejection—so they just latched onto the gynophobic fighter pilot Koujiro instead, the poor bastard. Since Tylor is perhaps the hardest to read character in anime history, he may have rejected them quite deliberately. A later comment implies that he really was paying attention to what they were saying. After all, the girls did take it pretty well, realising that they shouldn't rush to give themselves until they find the one person who's right for them.
• In Otome Youkai Zakuro, Ganryu is in a canonical OT3 with twin sisters Bonbori and Hozuki.
• The Hitachiin twins admit to playing this up to get clients in Ouran High School Host Club. Among other things...
• Persia, the Magic Fairy: The G-rated version — Persia has a dream about marrying both of the Muroi twins.
• Pokémon: The Series:
  • James could have a Twin Threesome Nightmare, considering his partner/best friend Jessie and the ex-fiancé he's been running from for years (stated as the reason he ran away from home in the first place), Jessiebelle, are nearly identical. You'd think he would've run from Jessie the first time he saw her; it's implied that James either doesn't see it or it's his subconscious reason for being with Jessie in the first place (since he originally had a crush on Jessiebelle).
  • Brock has probably had many a fantasy about having an orgy with the hundreds of Nurse Joys and Officer Jennies out there... which is now an Ascended Meme thanks to this episode.
• In Ranma ½, after Ranma has accidentally created a clone of his female half, Kunō comes across two Pigtailed Girls, hugs them, and says "It's like holding roses with both arms!" before being pummeled. Disappointingly (as the concept of Kunō chasing two girl-Ranmas would have fueled endless comedy), this is treated as a single-panel joke.
• In Red River (1995), Kikurri ends up marrying twin sisters Ryui and Shala, after it is revealed that they have the same taste in men and as a result have been taking turns to go see him... and he has gotten both of them pregnant. And they both give birth to twins!
• Sekirei: Kaoru Seo's two Sekirei, Hibiki and Hikari, are identical twins (only told apart by their bust sizes), and at one point he states that he was late because they "kept him up all night". The twins' reaction imply he wasn't making it up, and the manga's epilogue confirms it by revealing that his four children were born all on the same day.
• In Special Duty Combat Unit Shinesman, this is the main motivation for The Lancer: "I can't die yet! I have a date with Turkish twins!!"
• In Strawberry 100%, Junpei, after discovered that Aya (his Meganekko schoolmates) is the mysterious girl with the strawberry panties, imagine to hug and grope both the nerdy-Aya and normal-Aya despite them being the same person.
• Once in To Love Ru Darkness, Momo tease Rito about the possibility of having a bath with both Yami and Tearju.
• In Utawarerumono, there's Oboro and the twins, Dori and Gura.◊ Be warned though, they're all guys.
• Ayakashi Triangle: When Matsuri is split into a boy and girl, Suzu immediately imagines them both naked and fighting over her.
  Suzu: Wow, wow, wow! I'm in trouble...

• Subverted in Watchmen: Laurie wakes up to find Doctor Manhattan has duplicated himself in order to "please her" but ends up freaking out.

Of course, snobbish as she is, Monet didn't want to continue the conversation. Later on, when the three of them were part of X-Factor Investigations in X-Factor (2006), it turned out that: A) Monet was actually interested; B) Jamie actually did use his powers to improve his sex life, but in a different and more obvious way, by sleeping with both girls during the same night. Later, after Jamie Madrox married Layla Miller, it was confirmed in at least one issue that this Trope was played straight.
• Subverted in Sonic the Hedgehog (Archie Comics) with the backstory for the minor characters Lyco and Leeta Wolf.

  Well, it always did take two of them to compete with one of me.
• Parodied in Alan Ford: in one issue corrupt and childish business man Sem Brandelli picks three beautiful girls at his party for seemingly an orgy to show how much of a man he is... but as soon as they're alone, he makes the three girls exercise with some gym tools while moaning in pleasure to fool listeners, so that he appears to be fine and rested while the three girls are pooped and sweaty. One of them even compliments him for such clever ruse.

  Chloe: You were thinking about having two of me around, weren’t you?
  Marinette: Well, that’s not a bad thing is it? Just think, it would be like you, but…symmetrical. Compare and contrast….
  Chloe: You will not be comparing me and contrasting Zoe, do you hear me! Nope! Nada! Not at all! Especially with whatever devious thoughts are going through that head of yours! Only I can think deviously around here, stop it! Especially if they involve me and my half sister!

    Scruffy Xander: Yeah, we checked out some stuff in the car on the way over... Fingerprints!
    Anya: Well, maybe we shouldn't do this reintegration thing right away. See, I can take the boys home, and... we can all have sex together, and... you know, just slap 'em back together in the morning.
    Suave Xander: She's joking.
    Scruffy Xander: No she's not! She entirely wants to have sex with us together. Which is... wrong , and, and it would be very confusing.
    • Especially since the second Xander was played by Nicholas Brendon's real-life identical twin.
      Anya: It's not like it'd be cheating. They're both Xander.

Who had suffered so much. But the Doctor figured out a way to save the younger Amy still, but doing so would kill off Older Amy and Rory is a bleeding heart and tried save both. ... Doctor Who is weird sometimes.
  • The "Night and the Doctor" DVD extras show where River may have got the idea. They feature multiple Doctors and Rivers in the TARDIS, but she's the only one to bring up the possibilities (mainly because there's never more than one of her in the same room at once).

• Played with in a Saturday Night Live skit from Jennifer Garner's hosting gig. Garner played one half of a set of twins, along with Rachel Dratch, who was made up to look hideous (including a half-formed baby arm sticking out of her head). The two dressed identically, and went on a date with two men, played by Jimm Fallon and Chris Kattan. Fallon got Jennifer, Kattan got Rachel. Kattan's character eventually walked out in disgust, while Fallon made out with Jennifer. The punchline of the skit? Rachel's character eating a slice of pizza while Jennifer's character made out with Fallon's, and saying, "Make out with her all you want—I'm the one with the vagina." Fallon's reaction? Giving the "O.K." hand signal. ( To top it off, there were implications that the twins were conjoined.)

• "Split Personality", a Tales from the Crypt episode has Vic (played by Joe Pesci) running afoul of two deliciously beautiful and wealthy twins.

They discover the falsehood and end up sharing him. They decide to just split him... literally, down the middle, after they cut him up with a chainsaw, starting with the nether region!
• Jack from Will & Grace has, as his life's ambition, to one day meet and have sex with a pair of male identical twins. Will once actually invited over a pair of gay identical athletic twins just to make Jack jealous.

    Attached at the sides!
  • Less Squicky variation in their song "You Only Want Me 'Cos You Want My Sister" (which isn't about Evelyn Evelyn but a pair of non-conjoined identical twins):

    This ain't no two-for-one bargain here, mister
    'Cos I'm much more than just twice shy, I've had enough two-timing guys
    Who only want me 'cos they want my sister.
• Tragically and Squickily averted in the Vermillion Lies song "Long Red Hair", which is about conjoined twin sisters connected by their long red hair. One of the sisters marries a man that the other doesn't care for, to the point that she prevents her brother-in-law and sister from consummating their marriage. The man tries to fix this by cutting the twins' hair, but it only results in his wife and sister-in-law bleeding to death from their hair.
• Not one but two different rap songs mention Tia and Tamera Mowry of Sister, Sister fame in this fashion, both making puns on other shows related to them.

Whether or not it would have ended up as a Twin Threesome Fantasy is left out, as romantic options weren't available for the game (Maya probably would go for it, but Meena probably wouldn't). Sadly, all hints of this were purged from the U.S. version when they removed the party talk option.
• Dead Rising 2 has Amber and Crystal Bailey, who fondle one another, fondle other women, and poke fun at Chuck's lackluster "performance".

• In Assassin's Creed Origins, during one mission you're told to go to a brothel and speak with the "legendary twins" who work there, because they have information about the man you're hunting.

Visual Novels

• Tsukihime pseudo-sequel Kagetsu Tohya features the unlockable side story "Flower of Thanatos", where one of the possible options is to have Shiki have a passionate threesome with maid twin sisters Hisui and Kohaku.

• In Higurashi: When They Cry, Oishi approaches Keiichi in a library while he was meeting with Shion. As Oishi already knew that Keiichi and Mion were close, he then proceeds to tease Keiichi about "two-timing with the Sonozaki twins" (Keiichi protests this, though Shion simply ignores it). It's even more apparent in the arc where Shion is introduced, though in that case Keiichi doesn't realize she's a different person (he thinks it's Mion, pretending she has a twin—not helped by the fact that at one point she actually is, too). Cue traditional Higurashi hijinks and inevitable bloody murder.
• In Yearning: A Gay Story, Ashleigh and Leigh are identical twins who aren't shy about proposing threesomes to men. Adam and Carlos are initially interested in them, but the reality turns out to not live up to the fantasy with the men being too weirded out by having sex with two demanding women they can't distinguish from one another or even get the names of right to find it enjoyable.

• In Homestuck, Karkat has a brief fantasy involving Jade and Jadesprite.

Given the number of other people who were likewise duplicated, it has presumably come up several times, from members of both genders.
  • Given the scope of the duplication, it likely occurred all over in endless permutations. Relatively happy endings probably include the open-minded and those for whom both sides of the couple were duplicated an equal number of times.
• In Evil, Inc., a character discovers that a robot duplicate of her is fully functional, and decides to borrow it for the weekend so her husband can live out "THE Fantasy".
• In Least I Could Do, Rayne's brother Eric gets a very real shot at fulfilling this fantasy when a valentine arc sets him up with twins. However, his blows his chances by first bragging to everyone how he's on a date with twins instead of paying attention to the same twins, then tries to take them to an extremely low-budget hostel. To summarize: he ruins his chances with a sexy pair of twins because he wants to save some money. Yeesh. Worse: it's his brother, a medical doctor who is generally regarded as wealthy. Damn cheapskate...
• In Umlaut House here Volair uses his wife's time portal to do this in a rare example where the twins involved are male (and knowing Volair it could have also been an instance of Screw Yourself).

• In Turn Signals on a Land Raider, here. "Twins They Were!"
• In Rogues of Clwyd-Rhan, Kel's husband Jodoque has some interesting fantasies (mildly NSFW) after meeting Kel's two near-identical sisters (unlike her they have fairy wings; long story). Later on he's slightly less enthusiastic when one of the winged sisters gets into bed with him (nudity) and pretends to be Kel. Actually it was a disguised Kel all along (yup, they're still naked)... or was it?! Either way, the sisters planned it as a practical joke when they saw Jodoque's reaction to them.
• Ménage à 3:
  • Zii not only had this fantasy, but it was real — with a set of triplets.
  • Dillon's sleazy boss has Dillon dress up as Amber's twin to invoke this, because he doesn't want to make actual twin sisters commit incest.

• Grrl Power:
  • The backstory of minor characters Olivia and Tony is half-sibling/cousins due to their father having slept with twins at "a college party or something." Olivia also implies the relationship is ongoing, as "It was like a god damned Sitcom growing up"—especially because their grandmother loves using a homemade Laugh Track.
  • Main character Harem invokes the trope with her name and power: she can split herself up into up to five non-identical copies and has used it for the obvious Power Perversion Potential.

• Subverted in Oglaf. While trapped in his Lotus-Eater Machine, Ivan's love interest says she's delivered twins and shows him... two miniature copies of herself making out. Rather than be a turn on, it's the sight that makes Ivan briefly realize it's All Just a Dream.
• Sluggy Freelance: When Riff's ex-girlfriend shows up half-naked at his door, he shuts it in her face. Then she shows up with her clone. He still shuts the door, but it takes him longer.

  Joey: Haha, that's what I'm talking about!
  Mordecai: I was speaking—
  Joey: Yeah, you said it!
• Towards the end of Chapter 2 of Tiger, Tiger, Jamis has a dream in which he's accosted by multiple versions of Remy and Ludovica, all of them clamouring for his support and attention. It's a pretty straightforward metaphor for how he's torn between his loyalty for his friend/captain and his fiancee, but it suddenly veers into a different sort of subtext towards the end:
  Jamis: Oh don't be like that! I'm a big man, there's plenty of Jamis for all of you!
  • Then subverted, where the dream twins make their displeasure with the idea of Brother–Sister Incest clear.

Then one day he unexpectedly walks into her dorm room and finds that "she" is actually a pair of bi twins, who love to have sex pretending one of them is him. They invite him to join, but he's so freaked out, he leaves and breaks up with her/them.

Western Animation

• Archer: Archer mentions that he not only had a threesome with twin girls, but that they were both actual princesses! It's actually an oddly touching reference, as he states that such situations were the only times he ever cheated on Lana. He's of course a pig, but that's pretty much the most impressive complement he's ever given Lana; that she's as amazing as a ludicrous fantasy.
• Played with in a Danny Phantom episode where Tucker dreamed himself with two duplicates of a female character named Star (who in "real life" has no twin).
• In Daria, Brittany thinks Kevin is going with both Daria and Quinn. His response: "Whoa! Twins!" (FYI: Daria and Quinn are blatantly not twins, Kevin is just very stupid.)
• In Dr Zitbags Transylvania Petshop, Dr. Zitbag has a mutual attraction with his neighbors, the Exorsisters.
• Duckman:
  • An episode episode has blond twin bombshells hire Duckman and Cornfed to "help" with their love lives. Nothing comes of it, because Duckman can't get over his guilt towards his dead wife, and Cornfed has some sort of off-screen breakdown long before they get near a bed.

• Rick and Morty In "Bethic Twinstinct", 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 (and Rick, Summer and Morty) can only hear and not see what happens next, it's heavily implied to turn into a threesome soon after, with Jerry getting to bang both clones of his wife.
• Sonic Boom: In "Mech Suits Me", while under the influence of a symbiotic suit that turns him increasingly evil, Sonic hits on the twins Staci and Perci right in front of Amy Rose. When freed from the suit, Sonic claims to not remember anything, but screws it up by fondly commenting on how hot Staci and Perci were, pissing Amy off.
• In an episode of Stroker and Hoop, this situation comes up with a pair of hot blonde twins. However, it turns out they are members of the "Kind Cannibal Cult" which harvests the vestigial organs from people so they can eat them.
• Tangled: The Series: "The Return of Strongbow" heavily implies that Flynn Rider once had an "encounter" with a warlord's twin daughters.
• Hank Venture lusts after both Nancy and Drew Quymn in The Venture Brothers, but they both only have eyes for Dean (who in a subversion of the trope is interested in neither).
• Hekapoo from Star vs. the Forces of Evil has had literally hundreds of clones and seeing how much Ship Tease she's had with Marco (especially with him as a Future Badass), things could get very interesting.
