History Main / TwinThreesomeFantasy

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]]FridgeBrilliance 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 ThirdWheel.[[/note]]

* Features in the Modern AU ''WesternAnimation/HowToTrainYourDragon'' fic ''[[https://www.fanfiction.net/s/13122923/1/Confusion Confusion]]'', which adds the OC of Astrid's twin sister, Lillian, who has had an incestuous relationship with Astrid since they were young until she and Astrid independently meet Hiccup and each end up falling for him. It should be noted that Hiccup's relationship with them started because he met each separately and a complex chain of events led to the sisters thinking they were seeing him on his own while Hiccup assumed the two were the same person until he met them at their flat, leading to their decision to pursue a triad once Hiccup confirms he's independently attracted to each of them.

* It ''was'' brought up with Jamie Madrox (ComicBook/MultipleMan) a mutant hero who can make far more than two clones of himself. Siryn/Banshee (Theresa Cassidy) of ComicBook/XForce[=/=]X-Corporation[=/=]ComicBook/XFactor2006 has always had a crush on him, and when they were working together in Paris, she was shown to be really interested in the potential, even asking their teammate M (ComicBook/MonetStCroix) something along the lines of "Come on, are you telling me you never thought about it?". 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 ''ComicBook/XFactor2006'', 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, [[spoiler:[[MesACrowd 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.
