History Main / NaughtyByNight

* ''Anime/CodeGeass'': Nina [[MeaningfulName Einstein]] and the infamous [[CargoShip table scene]]. Nunnally actually ''wheeled in on this'', but fortunately she was blind already and ([[WiseBeyondTheirYears hopefully]]) too young to properly...''interpret'' any sounds she might have heard.

Compare SeeminglyWholesomeFiftiesGirl and CovertPervert. Contrast AggressiveSubmissive.

* ''VideoGame/JetForceGemini'': Running a mine in Rith Essa with his brothers isn't the only job Fishface has, it's only the one he has ''publicly''. Later in the game, he can be found working as an emcee in Ichor's exclusive Night Bug Club, where Juno and Vela can talk to him to request a song from a selected list.

-> '''Courtney''': They'll believe it, because it's their worst nightmare. Elizabeth Purr, the very picture of teenage perfection, obliterated by perversion?

-->"God, Woody, you didn't tell him about 'Cats', did you? It's not every girl who [[NoodleIncident loses her virginity in a Broadway show...]] I'll bet I can get us some tickets. ''Meeoww.''"

-->"Ah, Fred. You look all fresh and sweet, but I hear you at night in your room with Gunn. The things you say. I'm lying there, listening, [[ADateWithRosiePalms hands under the covers... I can't help myself. It's so... gripping]].

* ''Anime/CodeGeass'''s [[HotScientist Nina]] [[MeaningfulName Einstein]] and the infamous [[CargoShip table scene]]. Nunnally actually ''wheeled in on this'', but fortunately she was blind already and ([[WiseBeyondTheirYears hopefully]]) too young to properly...''interpret'' any sounds she might have heard.

* A [[{{Manga}} Hentai Manga]] take on this: ''[=WereSlut=]'' (unfortunate name [[CompletelyDifferentTitle created from whole cloth]] by Eros Comix, the US distributor) is about a shy college student named Kimiko who takes a magic beauty pill to make her attractive enough to win her childhood friend (read: [[HollywoodHomely she takes off her glasses]]). It works, but, due to the magic pill being past its expiration date, it keeps kicking in whenever she gets aroused. After the first time, though, it also kills all her inhibitions.
** Ditto for the manga/anime ''Sprite: Between Two Worlds'', wherein Manami, a severely repressed and meek college student turns into Nami, an outrageously uninhibited flirt whenever she's put into any situation that is too much for her to handle. The catalyst is her cousin Toru, who convinced Manami to be more confident around him when they were young by convincing her she was really Nami.
* In the {{ecchi}} manga ''Manga/MyBalls'', the main character's primary love interest Minayo is a sweet, kindly young woman who works at a daycare center. When she gets drunk, however, she goes into what the protagonist describes as "full-blown nympho mode". Unfortunately, said protagonist can't have sex for a month or the demon sealed inside his balls (hence the name of the manga) will be released and cause {{The End of the World As We Know It}}. Minayo happens to be an alcoholic, and HilarityEnsues.
* ''Anime/ParanoiaAgent'' has an episode that plays with this. Harumi Chono is a quiet, conservative, mild-mannered school teacher by day, but at night her [[SplitPersonality other personality]] takes over--Maria, a popular prostitute. When Harumi gets engaged, she starts trying to desperately get rid of Maria before her wedding day, which causes Maria to fight back.

* In a way Nyamo-sensei of ''Manga/AzumangaDaioh''. While she's generally straight-laced and down-to-earth in contrast to [[HardDrinkingPartyGirl Yukari]], the one who you'd expect to have a wild social life, Yukari makes a comment about her Nyamo "not being alone" in a previous summer, and RelaxoVision or not, the hilarious incident where she gets drunk and gives TheTalk implies she's fairly experienced.
* In the manga ''Manga/CrimsonSpell'' the protagonist Valdrigr is under a curse that causes him to turn into a rampaging demon. The trope kicks in when the Halvir, wizard Vald has recruited to help break the curse, decides that the best method of quelling the demon's rampages is to have sex with him - after the first few instances, it becomes clear that demon-Vald is increasingly less interested in violence and more interested in getting it on with Havi.

* Aurora was like this in ''ComicBook/AlphaFlight'''s early years, exaggerated by her SplitPersonality. One persona was Jeannie-Marie: strict, stuffy schoolmarm teaching at the same girls' school she was raised in. And then there was ''Aurora'': sultry, adventure-loving, free-spirited partier.

* In ''[[FanFic/APikachuInLove A Pikachu in Love]]'', Pikachu is worried that this is what Ash and Co. will think if they catch him sneaking off at night to meet Pichi, and doesn't want them drilling him for questions on the matter. [[spoiler: That still doesn't stop Misty from finding out, though she doesn't press the matter and keeps it a secret from the others even after the ending.]]

[[folder:Film]]

* The red-headed librarian from ''Film/{{Tomcats}}'' looks like a plain, uptight young lady. She (and her grandma!) are also into S&M.

* Somewhat subverted in the film ''Film/BlindDate'' where Walter's sister-in-law tells him not to let the date get drunk as she goes wild. This information is relayed to him via his brother who adds lots of leering to the information. Cue the man getting his date, Nadia, drunk, to find that she goes wild in a drunk-driving, crash-the-car, ruin-the-evening way.

* The title character of the {{Sexploitation}} film ''Film/Angel1984'' and its sequels in ''Film/TheAngelTrilogy''. The tagline for the original movie was "High School Honor Student By Day. Hollywood Hooker By Night".
* In ''Film/GuiltyOfRomance'', Mitsuko is a professor at a university during the day and a prostitute by night.
* ''Film/MySuperExGirlfriend'': Vaughn thinks Jenny is this on first seeing her, saying that though she looks like a librarian on the outside, inside there's a wild side. He's more right than he knows. As her SuperHero alter ego G-Girl, she's revealed to be a [[SexGoddess very enthusiastic lover]] she [[ManOfSteelWomanOfKleenex accidentally injures Matt]] and [[DestructoNookie destroys his bed]] with her SuperStrength.

* A relatively tame version occurs in ''Literature/GoodOmens''. Sweet little old lady and part-time medium Madame Tracy also offers appointments for "strict discipline and intimate massage every evening except Thursdays", and there are hints that she goes a little further than that on Thursdays.
* In ''Literature/SavingZoe'', Teresa is a pretty preppy girl who acts and sings. By night, she hangs out with drug dealers and porno producers. The same could be said about Zoe, who seems like a perfect bubbly girl but smokes drugs and has sex when her parents don't know. This tendency leads to Zoe's death.
* Erika Kohut in ''Literature/ThePianoTeacher'' by Creator/ElfriedeJelinek is a very unhappy example. Her [[MyBelovedSmother oppressive mother]] has totally managed to suppress her natural sexuality, so she tries to make up for it by secretly and obsessively pursuing weird, unhealthy perversions, though she can still barely feel anything. When she gets into an affair with her student, he soon gets freaked out by her tastes.

* ''Series/OnTheBuses'' long-suffering Olive would love to be Naughty By Night, but her miserable husband Arthur would rather sleep. Actually, he'd probably rather do his taxes...
* Effy from ''Series/{{Skins}}'': innocent schoolgirl by day, FilleFatale by night.
* Sheila from ''Series/ShamelessUS''. By day she's a sweet agoraphobic and germaphobic housewife. But at night she is very very into pegging filthy alcoholic Frank.

* ''Series/TwinPeaks'' -- Laura Palmer is a normal high school girl by day, but a prostitute at night, among other things. Or, as she says in Main/TheMovie, "Night time is my time."
* ''Series/{{Reno 911}}''. Deputy Weigel and her boyfriend Craig both appear to be socially-awkward nerds, but what we see of their sex life is quite... adventurous. Subverted in that [[spoiler: Craig turns out to be a serial killer]].
* Subverted on ''Series/PersonOfInterest'' where a [=PoI=] is a dedicated workaholic doctor but seems to spend her nights going to night clubs and picking up men. However, a more detailed investigation reveals that she is actually [[spoiler: stalking the man who raped her sister and caused the sister to commit suicide. The doctor is simply building up her resolve to murder the man.]]
* The VictimOfTheWeek in the ''Series/MurdochMysteries'' two-parter "Stroll on the Wild Side" is a quiet librarian, but the autopsy reveals she has a rose tattoo on her ankle, which is not something a respectable woman in 1900s Toronto would be expected to have. It turns out she's been picking up men in a seedy tavern, apparently just to add some excitement to her life.

* The viewpoint character of Amy Rigby's "Wait Til I Get You Home" is shy -- but she knows what she wants:
-->''You make me so happy\\
But there's all these people around\\
So wait til I get you home\\
And the walls come down...''

''Bad as can be, yeah you know I'm not so innocent.''\\

* Fantine in ''Theatre/LesMiserables'' is fired from her factory job when she is discovered to have a child, and her fellow workers claim that she is a prostitute. However, she had only ever had one lover, who had abandoned her, and it is only after she is fired that she has to become a prostitute.
* The song "Miss Byrd" from ''Theatre/CloserThanEver'' is about a secretary exulting in how no one who sees her would think that she's anything but "that dull Miss Byrd," yet she has secret trysts with her superintendent.
* Parodied in ''Theatre/TheMusicMan'': The town gossips manage to convince the Professor that [[HotLibrarian Marian the Librarian]] is NaughtyByNight primarily because she reads "racy" books by "Chaucer...Rabelais...[[Creator/HonoreDeBalzac Balzac]]" and was kind enough to befriend the town outcast. She's not, but he falls in love with her anyway.

* Nekoko from ''Yume Miru Kusuri'' [[spoiler:though this is more of drug effect]].

* Possibly Litchi from ''VideoGame/BlazBlue''. Despite her incredibly skimpy battle clothes, her personality is fairly conservative. However, supplement materials and a couple of gag endings say that when she gets drunk she gets rather...insistent.

* Website/CollegeHumor: In "[[https://www.youtube.com/watch?v=HIPJrrQlxzY The Six Girls You'll Date in College]]", there's 'The One Who Goes to Church', who's easily impressed by the NiceGuy AudienceSurrogate, but in the bedroom is apparently heavily into bondage.

* The title character of the 1984 {{Sexploitation}} film ''Film/{{Angel}}'' and its sequels. The tagline for the original movie was "High School Honor Student By Day. Hollywood Hooker By Night".
