A SisterTrope to LadykillerInLove, this is what happens when TheCasanova and the FemmeFatale (Or [[TropesAboutPerverts some similar character archetypes]]) are both trying to seduce each other for their own purposes at the same time. Most of the time, there is no sincere romance between the two, each one is [[ManipulativeBastard strategically putting the moves on the other]], trying to seduce them to join [[FaceHeelTurn their]] [[HeelFaceTurn side]], give them information, or obtain the MacGuffin for them. As such, this is often one of the EspionageTropes. Often, a Duel of Seduction ends in a SexFaceTurn. In the mean time, it's a good opportunity for copious {{Fanservice}}.

There is a bit of a DoubleStandard with this trope. Because [[ReallyGetsAround a woman with a lot of sexual experience and drive is a lot less socially accepted]] than a man with the same, more often than not the [[TheCasanova seducer]] is on the side of good, and the [[FemmeFatale seductress]] on the side of evil. The seducer is more likely to [[HighHeelFaceTurn convert the seductress to his side]] in the end, and she often loses much of her power and appeal in the process because GoodIsDumb.



[[folder: FanFiction]]

* ''FanFic/ABrighterDark'': A relatively low-stakes but no less interesting example occurs when [[TheTease Solei]] and [[TheCasanova Laslow]] meet for the first time. It starts with him trying to invite her out to a night of tea, and then somehow spirals into an argument over who is superior in their skill of enrapturing the heart of their targets; him citing his longer lifespan and thus longer experience, and her citing her overall superior skill. It ends with her eventually deciding to prove her point by seducing him on the spot. After a rather...intimate speech, he quickly has to concede that she is clearly the expert of her field.
** [[spoiler: Takes on another interesting layer with the strong hint that he might be her father...]]


[[folder: Film ]]

* ''Franchise/PiratesOfTheCaribbean'':
** The scene in ''Film/PiratesOfTheCaribbeanDeadMansChest'' with Elizabeth Swan and Captain Jack Sparrow, each trying to get the other to do something in return for something else. She wants to prove he's not as bad as he pretends, he...well, his motivations seem transparent, but on the other hand, it's [[WildCard Jack]].
** Jack and Angelica in ''Film/PiratesOfTheCaribbeanOnStrangerTides''.
* Film/JamesBond obviously is a good candidate for this. The most memorable scene has to be ''Film/{{Thunderball}}'' with Fiona Volpe. It's notable for ''both'' failing to significantly affect the other's disposition.
* ''[[https://en.wikipedia.org/wiki/The_10th_Victim The 10th Victim]]'' is a movie about citizens engaging in a DeadlyGame where one contestant hunts the other. While this sort of thing isn't ''required'', it is indeed ''encouraged'', seeing as the game is televised. The seductress here - played by Ursula Andress - attempts it, but [[InLoveWithTheMark falls in love with her intended victim.]]

[[folder: Live Action Television ]]

* The ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS3E2TheEnterpriseIncident The Enterprise Incident]]". The seductress is a Romulan Commander WorthyOpponent, and oddly enough, the seducer is not Kirk, but rather {{Spock}}.
* ''Series/GossipGirl'' - Chuck and Blair, nearly all the time. Subverted as they do in fact actually love each other [[CannotSpitItOut but are just incapable of admitting it to each other]] and are/were in fact, the most popular pairing on the show. Blair is also not portrayed negatively or evilly.
* In ''Series/{{Firefly}}'', a good one between Inara and Saffron. Both recognize what is going on.
--> (Klaxon Sounds)
--> '''Inara''': I guess we've done enough lying.
--> '''Saffron''': You're good.
--> '''Inara''': You're amazing, who are you?
--> '''Saffron''': [[HeHadAName Malcolm Reynolds's widow]].
* Annie Walker and Simon Fischer for several episodes of ''Series/{{Covert Affairs}}''.
* PlayedForLaughs in an episode of ''Series/{{Chuck}}''. Spy couple Chuck and Sarah are both trying to seduce ''each other''. Over their ''wedding plans''. HilarityEnsues when they both realize what the other is up to. And it gives five minutes of [[MsFanservice Sarah]] in a belly dancer outfit.


[[folder: Literature ]]
%%* ''Literature/DangerousLiaisons''
* Creator/FrankHerbert's ''Literature/HereticsOfDune''. Murbella tries to use an Honored Matre technique to seduce and mind control Duncan Idaho's ghola, but his secret Tleilaxu conditioning allows him to seduce and condition her instead.
** They actually manage to condition ''each other''.
* In ''Literature/TheDemonPrinces'' final volume, Alice Wroke is under [[IHaveYourWife orders]] from the villain to seduce the hero. He, being several steps ahead of the game, obligingly plays along. [[spoiler: Although he doesn't sleep with her.]]
* Implied to have happened in two of the ''Literature/LordDarcy'' stories. In one, a female spy zaps Lord Darcy with an infatuation spell. Darcy realizes what happened, and spends the night letting her get false information out of him.
* In the ''Literature/WingsQuartet'', Tamani seduces Yuki, a spy for [[HunterOfMonsters troll hunter]] Klea, in order to get her to give information on Klea's whereabouts. [[spoiler: It is revealed that Yuki is a faerie and knew that Tamani was one as well. However, she did eventually develop real feelings for him.]]
* Literature/ElsabethSoesten is hired to recover incriminating documents from Lord Cuncz, the Baron of Leyen. She decides the best means of gaining access to them is to seduce the Baron. [[spoiler: And then she learns Cuncz was the one who hired her in the first place, and that he was seducing her by letting her think ''she'' was seducing ''him'' (and her own plan was built on pretending to fall for ''his'' seduction attempt). It didn't even have anything to do with his own plans; he did it entirely because he wanted to bed her.]]
* In the UrbanFantasy ''Literature/RedRoom'' series, succubus Shannon O'Reilly and seduction-trained agent Derek Hawthorne use their formidable skills on each other to get an advantage while being forced to team up. [[spoiler: They fall in love instead.]]
* In Jason Matthews's ''Literature/RedSparrow'', Russian SVR seductress Dominika Egorova is tasked to seduce CIA agent Nate Nash for information on a mole within the SVR. Nate had just been kicked out of Moscow and was just looking to get his career back on track in Helsinki when he stumbles on Dominika. Throughout their interaction, it's only Dominika who tries to seduce; Nate was only looking to recruit her as an asset. Yet they enter into a relationship anyway.

[[folder: Tabletop Games ]]

* ''TabletopGame/DungeonsAndDragons'':
** An ancient in-game joke: OnceUponATime a young lad and a young lass, wizards' apprentices. They decided to exchange some magics. Both cheated and cast CharmPerson to ease the bargain, and both failed their saving throws horribly. They lived HappilyEverAfter and even died the same day.
** One source describes two very unlikely lovers, [[OurAngelsAreDifferent the agathinon Janarr]] and the [[HornyDevils erinyes Nalura]] hiding out in mortal disguise on the Prime. They sort of just did their jobs ''too well'' � she tried to seduce him, he tried to turn her attitude up to celestial standards. Before they knew whom exactly they faced, both succeeded. They had to hide from their respective bosses from that point on, though.
* This is one of the many, many ways Maids can compete for Master's love in ''TabletopGame/MaidRPG''. They can do this with ''[[LesYay each other]]'' as the target of seduction.


[[folder: Videogames ]]

* ''VideoGame/KnightsOfTheOldRepublic'' plays the hell out of this one in the trial scene on Manaan. It starts as a straight up version of this, then gets interesting.
* An interesting version (with PsychicPowers) turns up as Samara's loyalty mission in ''VideoGame/MassEffect2''. Shepard is required to catch the attention of [[spoiler: Samara's daughter,]] Morinth, who [[HornyDevils kills people by sleeping with them]]. This requires three steps: first draw her attention by making a scene in her favorite bar (punch people, stare down [[ProudWarriorRaceGuy a krogan]], [[ArsonMurderAndJaywalking dance really well]]), then pique her interest in conversation, and then she takes Shep back to her apartment and tries to turn her telepathic abilities against the commander, who tries to resist through sheer [[TheCape virtue]] and/or [[AntiHero badassery]]. It's possible to blow either the second part (in which case she walks out and you fail the mission) or the third ([[spoiler: she draws Shep under her spell and is about to strike [[BigDamnHeroes when Samara blows the door in]]]]). Oh, and Morinth is an [[DiscountLesbians asari]], so Shepards of either gender can participate.
