History Main / SexByProxy

* In the ''Manga/GhostInTheShell'' manga, Motoko, Kurutan, and Ran all experiment with a new pornographic software that they're developing that allows the users to feel what everyone else is feeling. Batou is given the task of interrupting her "shore leave", and shortly after he hacks his way in, he starts to feel ''icky'' because his male cyborg body (and brain) didn't have the receptors needed to process what a female orgasm feels like. It didn't help any that he also got infected with the cyberdrug they were using at the time either.

* In Chapter 290 of ''Manga/AhMyGoddess'', Belldandy and Keiichi are overshadowing another goddess and mortal who fell in love. Judging by the the last panel on page 23, the past couple were lovers. Which means Bell and Kei are lovers, by proxy.

* This seems to be at least a significant chunk of the principle behind the Shrieky Girls of ''ComicBook/DoktorSleepless''.

* A more PG-rated version occurs in ''Fanfic/KyonBigDamnHero''. Due to being in tune with Haruhi's emotions at all times, especially if the emotions are particularly strong, Koizumi ends up [[LuminescentBlush extremely flushed]] when Haruhi and Kyon are making out.

* In ''WebAnimation/RedVsBlue'', AIs are able to possess others by entering the AI slot in their armor, often leaving the possessee still conscious. Fanfic takes this to its logical conclusion with PowerPerversionPotential.

* In ''Film/Ghost1990'', Sam uses Oda Mae's body to say goodbye to Molly one last time. Although it's more of a PG-rated Makeout by Proxy.

* In ''Film/{{Freaks}}'', one of the conjoined twins is shown to get aroused when her sister is kissing her boyfriend. Since the sister and boyfriend proceed to get married and have sex, one can assume the trope is in full effect.
* ''Film/StrangeDays'' involves illegal devices which can record and play back memories -- giving the user all of the sensory input felt by whoever was being recorded. The recording include sex, of course (parts of a couple of raunchy memory recordings are shown, both for sale and for personal use). It's probably a huge part of the market.
* ''Film/{{Brainstorm}}'' also features a memory-recording device, and one of the scientists working on it uses it to make a porno.
* In ''Film/{{Surrogates}}'' some people willingly let others access their robotic avatars to feel the pleasure of living in a perfect body (and touching it).
* In ''Film/StarTrekNemesis'', Shinzon uses his Viceroy's PsychicPowers to MindRape Deanna Troi while she's having sex with her fiancé Will Riker. She ends up paying them back for it by using the psychic connection to target the ''Scimitar''[='=]s bridge with the ''Enterprise''[='=]s weapons.

* ''Film/EnterTheVoid'': The main character is killed about 15 minutes into the movie and spends the rest of it as a disembodied spirit. There are numerous occasions where he observes people having sex and flies into their heads to experience it from their point of view.

* In a malicious twist, Joshua from ''Literature/DoraWilkSeries'' experiences this when Dora and Miron finally make out... only from Dora's perspective, which makes things kinda awkward for him, since he's definitely straight.
* In Creator/RobertAHeinlein's ''Literature/StrangerInAStrangeLand'', when Jubal finally has sex with Jill and/or Dawn, he discovers that the entire cult has enjoyed their romp through their shared mental link.
* In ''Literature/TheWheelOfTime'', the Warder bond allows people to feel what others do. So when [[spoiler:Elayne and Rand]] finally have sex, [[spoiler:Birgitte (who is bonded to Elayne), Min, and Aviendha (who are bonded to Rand)]] all have to go off and get drunk so they can't feel precisely what is going on.
* Creator/WalterJonWilliams' ''Aristoi'', which is set in a future where everybody has wireless internet connections in their heads, has a science-fictional example.
* In the ''Literature/DragonridersOfPern'' setting:
** The mental link between dragons and riders can cause this effect. Generally, when dragons mate, their riders are pulled into the lust and wind up following suit whether they want to or not -- but it also works in reverse, most notably in the case of Lord Jaxom, who winds up with a strange, white runt of a dragon. Being apparently asexual, it has no interest in "flying" with female dragons, but it DOES seem to rather enjoy sharing Jaxom's feelings when HE'S off with a girl.
** In ''Moreta: Dragonlady of Pern'', Moreta's away from her queen, Orlith, on a time jump when she and Alessan resolve their attraction. As she's dozing off, Moreta thinks that Orlith would have liked Alessan's lovemaking, too.
* In the novel ''Literature/GeekLove'', conjoined twins Elly and Iphy have sex with a man. Elly wants it, and Iphy... doesn't. It gets even more squicky because the two share the same bottom half.
* In ''Literature/TheDresdenFiles'' novel ''White Night'', resident wizard gumshoe Harry and his apprentice Molly are trying to get an impression on the last moments of a woman who has mysteriously died. Because of Molly's talents with magical detection, she's the one who'd tasked with picking out the dead girl's last sensations. It turns out, her last moments were wrapped up in the lethal sexual ecstasy of a [[SuccubiAndIncubi White Court vampire]], and Molly catches the full blast.
* At one point in the ''Literature/SwordOfTruth'' series, Nicci links herself to Kahlan and then lets a violent brute have sex with her, forcing Kahlan to feel every sensation as if she were the one getting it.

* ''Literature/{{Animorphs}}'' doesn't give us all the details (it is a kid's book, [[WhatDoYouMeanItsForKids supposedly]]), but Visser One and one of her first human hosts did this with ''another'' human-Controller, resulting in [[UntoUsASonAndDaughterAreBorn a pair of twins]] with four "parents." And of course, other Yeerks probably wind up doing this quite a bit too.
* In Marge Piercy's ''Literature/WomanOnTheEdgeOfTime,'' the main character travels to the future and has sex with someone she meets there. It's only after the fact that she learns that the mechanism behind her time travel (which relies on a psychic bond between her and another person from the future,) meant that said other person was aware of the sex as it was going on.

* In the ''Literature/LilithsBrood'' series, the Oankali are a three-gendered race, and perpetuate that manner of relationship when they mix with humans. It roughlyly involves the ooloi being in-between the male and female and connecting their minds, so that they have sex mentally while never touching each other, only the ooloi conduit, and the ooloi enjoys all the feelings of both.

* In Creator/EmmaBull's ''Literature/BoneDance'', the protagonist has been ridden by two [[BodySnatcher Horsemen]] in the past. Now the Horsemen are in new hosts, together, and the protagonist discovers that having been ridden leaves behind a psychic connection between host and Horseman. [[spoiler: This is particularly traumatic because the protagonist [[NoBiologicalSex is neuter]], and thus has not had much experience with sex before this.]]
* At one point in ''[[Literature/TowerAndTheHive The Rowan]]'', by Creator/AnneMcCaffrey, the powerfully telepathic Rowan, while in the "can't keep her hands off him" early delirious stage of her first sexual relationship, has to be quietly told by one of her other housemates that she's "broadcasting".
* In the ''Literature/ApprenticeAdept'' novel ''Unicorn Point,'' Agape and Citizen Tan are pitted against each other in the book's TournamentArc in a game of "Seduction By Proxy.[[note]]The players are linked to two volunteer serfs as a voice in their heads, attempting to seduce each other in alternating rounds. The third and final round allows rape as a way to "ensure a finish". The serfs' memories are wiped of the game events.[[/note]]
* Among the many works of author ''Creator/RichardLaymon'', the book ''Body Rides'' is about a man who is given a magic ring which allows him to astral project and inhabit someone else's body. They are unaware of his presence, but he experiences everything they do, including their thoughts. Naturally, this includes sex.
* In Creator/PiersAnthony 's Incarnations of Immortality series, the book ''For Love of Evil'', Parry's late wife, Jolie, is bound to him by a spot of her blood on his wrist. One night, she convinces a peasant girl whose home Parry is spending the night at to let Jolie use her body to have a chance to make love to Parry. The act was consensual for all three parties involved, but it violated Parry's oath of celibacy that he'd taken upon joining an order of monks, and left him open to further temptation.
* ''Literature/TheMachineriesOfEmpire'': As {{Virtual Ghost}}s, Kujen and Jedao could only consummate their [[DatingCatwoman tumultuous relationship]] through [[WillingChanneler human anchors]]. In ''Revenant Gun'', Kujen's anchor [[DefiedTrope abruptly refuses]] to go through with it out of disgust for [[spoiler:the [[HumanoidAbomination secret]] behind Jedao's current CustomBuiltHost.]]

* On ''Series/{{Firefly}}'', River (a telepath) once walked by as Wash and Zoe were making out in the cockpit. She is [[DirtyMindReading able to feel what both of them are feeling]] and visibly reacts.
* When Phoebe developed her [[TheEmpath empathy powers]] in ''Series/Charmed1998'', she became capable of feeling the emotions of people around her. This led to a fairly {{squick}} implication of this trope when she was walking with Piper (her sister) and a guy was checking Piper out. Upon beginning to feel his attraction towards her own sister, Phoebe informed Piper of the fact, and the two decided to quickly move right along.

* In ''Series/Sense8'', the cluster of sensates can sometimes feel when one of its members is in the act. Essentially, this can lead to giant telepathic orgies.

* ''TabletopGame/{{Traveller}}'': There is one alien race in Traveller where all births are in mindlinked brother-sister pairs. These are each linked so closely that they are almost one individual. When they marry one pair marries another rather then one individual marrying another. SexByProxy is an unstated but obvious inference.

* ''Theatre/SideShow'' has a scene where the ConjoinedTwins and their respective love interests are on a Tunnel of Love ride. Violet seems to be able to feel Daisy's reaction to being kissed by Terry, and notes that it's much stronger than her own response to being kissed by her fiancé.

* In ''VideoGame/DragonAgeII'', this is brought up if Hawke romances Anders (the latter of whom is possessed by a spirit of Justice). When Anders tells Hawke that Justice disapproves of their relationship, Hawke can ask, "So, he's like an unwilling participant in our threesome?". Later, Isabela makes the same joke, commenting, "You, Anders... and Justice? Well, you know what they say - two's company, but three's better."
* ''Franchise/AssassinsCreed'': Expanded universe materials have confirmed that Animus users do indeed feel the physical sensations that their ancestors feel. Which means that all the times Desmond watched Ezio have sex he felt what he felt.

* "Webcomic/BooItsSex'': Christine says Tara's goals to get them "mad laid" and "live vicariously through [the girls]" sounds almost like she wants to possess them and have sex by proxy. Tara assures her she would never do that... without consent.
* A romantic version (and, presumably, at some point, a sexual one) occurred in ''Webcomic/AMiracleOfScience'', when [[HiveMind Mars]] falls in love. Prester meets a cute, female Martian, who is part of the Martian Hive-Mind, and they get along well... to say the least. When he then visits Mars, he finds that random people keep giving him flowers and smiling at him - because, after all, Mars LIKES him. (The series ends before their relationship can progress to the final level of intimacy, but one must imagine that it'll be SOMEWHAT awkward...)

* Someone is telepathically or otherwise linked to the characters, and can feel whatever they're feeling;

* In the ''Literature/HeraldsOfValdemar'' series, Talia has a permanent empathic link with her Companion that can't be blocked, even when her Companion is busy showing the Companion mares what a virile stallion he is. As TheEmpath, she's also treated to the emotions of her fellow Heralds whenever they're nearby unless she very carefully shields herself. Being initially roomed next to an [[AnythingThatMoves exceptionally randy]] trainee, it is no surprise that she later chooses to move her permanent quarters to a remote tower of the Collegium.

So, Alice and Bob are making the beast with two backs, so to speak. Except it's more of a beast with ''three'' backs. With or without them being aware of it, a third party is actively enjoying their encounter, and not in [[ADateWithRosiePalms the usual way]], either.

* When Phoebe developed her [[TheEmpath empathy powers]] in ''Series/{{Charmed|1998}}'', she became capable of feeling the emotions of people around her. This led to a fairly {{squick}} implication of this trope when she was walking with Piper (her sister) and a guy was checking Piper out. Upon beginning to feel his attraction towards her own sister, Phoebe informed Piper of the fact, and the two decided to quickly move right along.

** Olivia gets this in the episode "[Recap/FringeS01E17BadDreams Bad Dreams]]", as part of an ongoing psychic link with the episode's killer.

* ''Webcomic/GrrlPower'': How does an underage [[HornyDevils succubus]] who needs tantric[[note]]sexual[[/note]] energy gets fed without UnfortunateImplications? Well one of the ways is to be in the [[https://grrlpowercomic.com/archives/comic/grrl-power-795-dinner-belles/ general vicinity]] of sexual activity.

* In ''Manga/PetshopOfHorrors'', Leon is seduced by two different women in one night. It turns out that they're plant spirits who were using him to spread their pollen from one girl to another.

* In ''Machinima/RedVsBlue'', AIs are able to possess others by entering the AI slot in their armor, often leaving the possessee still conscious. Fanfic takes this to its logical conclusion with PowerPerversionPotential.

* In ''Film/{{Ghost}}'', Sam uses Oda Mae's body to say goodbye to Molly one last time. Although it's more of a PG-rated Makeout by Proxy.

* In ''Series/{{Supernatural}}'', demons (and humanized [[NotSoDifferent angels]]) abuse their possessed bodies for all the pleasures they can grant. This can include sexual experiences, and some demons can be quite flirty. One demon possessing a woman conceived a child and carried it to term, resulting in the birth of the "Anti-Christ", born with demon influence.

This tends to be a magic trope, although sci-fi versions exist as well. Often an upgrade of DirtyMindReading. It's FetishFuel, obviously, and a subtrope of PowerPerversionPotential.
