"To have such an immoral and lewd plan coming out from you, what a surprise."Uncharacteristically suggestive comments and thoughts from a character usually considered pure and innocent. Sometimes this is played straight and shows that a character is mature or smart enough to notice subtle themes their friends don't. Most of the time it's a trait given to a shy character to show they're not quite as mousy and meek as we think. Usually cued by fantasy segues becoming more and more lewd. This will always be fiercely denied by the character, especially if they're cantankerous and dismissive. The more comedic princess-like types often get this too, until it turns into a more overt Running Gag. Note that the title refers to covertness in the figurative sense, not the literal. This trope is also Truth in Television — you know who you are. Don't say it, otherwise you won't be one anymore. If the Covert Pervert is outed they may be subject to a girl getting set to Pervert Revenge Mode or even an Unprovoked Pervert Payback. Probably due to the often-seen Double Standard that women should not show their sexuality openly, over half of the examples of this trope are female, while perverted male characters tend to be obvious.

Anime & Manga
- Shino Aizawa of Aizawa San Multiplies dreams of being rather intimate with her crush, Souta, but she's generally too shy to admit it. However, she develops a Literal Split Personality sprung from her carnal desires, who is most pointedly not afraid to admit it, and the original (as well as duplicates based on other aspects of her personality) don't exactly deny what her libido is saying.
- Akikan! has Najimi.
- Several characters in Axis Powers Hetalia.
- England seems like a bit of prude until you get him drunk or learn about his people's sexual records;
- Japan has monologued before about the superiority of 2D over 3D:;
- Germany seems to have a thing for bondage and possibly bestiality (according to Italy);
- Hong Kong loves to make porny artwork despite China's protests and doesn't seem to regret it one bit;
- Hungary will beat up you and your entire army with her Frying Pan of Doom if you harm her husband Austria... unless you happen to be a good-looking young man attempting to molest himnote .
- Spain seems to be completely oblivious about sexual things (such as when France gropes him and he doesn't notice) and only an Accidental Pervert (pulling South Italy's curl without noticing it's an erogenous zone). Then it turns out he has rather elaborate, occasionally creepy fantasies about the Italian brothers. And he's part of "The Perverts Club"!
- The super sweet, motherly, tearful and humble farm lady Ukraine comes off as The Ingenue (especially in contrast to her sister who will loudly threaten a Groin Attack on a whim) with a case of D-Cup Distress or maybe Innocent Fanservice Girl in her introduction...but then she uses her breasts and cheerfully advises other people to the same.
- Azumanga Daioh
- Minamo is revealed to be this, thanks to too much alcohol and a poorly timed question from Tomo, prompting her to say "Let me tell you about men" and deliver a long speech on the matter. The speech itself is censored with calming music and relaxing scenery, but given the girls' reactions, apparently it was very... educational.
- Osaka is the only one who doesn't react to the speech with confusion (Chiyo) or embarrassment (everyone else), listening intently and outright telling Chiyo to be quiet when she tries to interrupt.
- Mizuki Himeji from Baka and Test: Summon the Beasts certainly qualifies. During an event were the summoned being spoke the characters true feelings, Himeji's confessed to have thought "weird thing" when the other were talking about ecchi things.
Mizuki: I think Minami-chan will use this chance to touch Akihisa-kun's chest and butt...that's too sneaky...”Minami: Wh, what are you saying, Mizuki! How can I do such a thing—eh, what? What did you just say? Touching...Mizuki, what were you talking about...”Mizuki: Ah! No, nothing! I'm not talking about touching him sneakily. Th, that...I'm just talking about improving the relationship with Akihisa-kun. I just said it wrongly!”Minami: Mizuki..what were you planning to do to Aki...”
- Also this from volume 7 of the novel:
- In B Gata H Kei, Yamada is a beautiful, intelligent, refined young girl... who cannot stop thinking about sex for even a second. Her life goal is to have one hundred sex friends.
Daisuke: Why does she suddenly stop talking and blush sometimes?
- In the manga version of Battle Royale, Mitsuko suspects that Kazuo Kiriyama is one and tries to seduce him. She's wrong.
- The hyperactive, flustery Cloudcuckoolander Oshiroi from Ben-To. When Satou asks her if she wants to join the Dogs, she thinks he wants to know if she wants to get gangbanged. She doesn't reject the idea outright, just says she'd prefer her first time to be one-on-one.
- Of all people in Bleach, we have Retsu Unohana as this. In Bleach on the Beach, her Number Two Isane was freaking out over a skimpy one-piece her sister, Kiyone, wanted her to wear, which was amusing enough. Unohana decides to intervene... This staid, primly-dressed, motherly woman takes Kiyone's side. And then reveals her own swimsuit... which is even skimpier. And then she uses her Death Glare to force Isane to wear the swimsuit.
- Sui-Feng. Holy SHIT, Sui-Feng. Who'd say that the coldest, more ruthless Tsundere in the Gotei is such a Yoruichi fangirl? Not to mention there's how, in an omake, she pinned Ukitake to a tree with kunai so people could take photos of him.
- When Ichigo tells Rangiku she can't stay at his place, she lets her skirt ride up and begins unbuttoning her blouse. Ichigo slaps his hands over his eyes and protests aggressively, telling her off... while all the time peeking at her body through his partially opened fingers.
- Tobiume frequently scolds Haineko for her shameless behavior, but joins her in trying to peep at Senbonzakura taking a shower.
- In Campione!, Liliana is depicted as a stoic, no-nonsense warrior, a firm contrast to her rival, the boisterous, shameless Erica. It is revealed that Liliana writes erotic novels in her spare time, and gets wild sexual fantasies about Godou. She's really embarrassed about anybody finding out about this.
- Tomoyo Dadiouji in Cardcaptor Sakura is calm, mature and refined in most situations. She also has a passion for dressing Sakura, the perpetually oblivious target of her affections, in a vast array of fetish-tastic outfits while she records her... and watching aforementioned recordings repeatedly... alone...
- Darker Than Black has an OVA that reveals that resident Yaoi Fangirl Kiko has introduced Yin, of all people, to the world of slash fanfic. Really dirty slash fanfic, at least one of which involved doing something unmentionable with an elephant.
- Nice dude and introvert Machiya from DEAD Tube claims he quite never filmed what always he wanted to put on Camera, the first thing he does after witnessing a pretty girl bludgeon a guy to death with a bat, is hold his camera tight and get a raging erection.
- Hio-tan of Denki-gai no Honya-san is a Yaoi Fangirl, but say that to her face and she'll vehemently deny it.
- Tsuyuri from Doujin Work acts like an emotionless girl most of the time and has a very youthful, sweet appearance. Still, she is one of the most perverted characters around, as evidenced by the extremely sadistic erotic doujinshi she produces. She also projects her fantasies on her friend Najimi, who she firmly believes to be a masochist.
- Mai, who works for Pilaf in Dragon Ball. When Pilaf said that they needed to find the "balls", Mai simply responded, "Perhaps between that man's legs." Pilaf and Shu didn't take it well.
- In Eyeshield 21, when Sena, Monta, Mamori, and Suzuna visit a bath house in order to talk to Kakei of the Kyoshin Poseidons, Mizumachi's attempts at peeping on the girls' side lead to the normally shy and quiet Sena having a vision of Suzuna, naked except for a towel held against her front.
- Fairy Tail has actually several examples of this. The most prominent would definitely be Erza with all her weird, often quite Stripperiffic armors, of which she states she prefers the Bunny Girl. Later, she buys a "seduction armor" which is essentially several types of Fetish Fuel packed into one piece of clothing. In the Fairy Hills omake, Levy also mentions that she apparently likes "sexy books", and when Natsu and Gray looks through Lucy's chest of drawers to find her underwear, they easily make an interested Erza join them. Plus, in the anime-exclusive Key to the Starry Skies arc, when Erza and Grey had a little stakeout together, she seemed… interested… in seeing Grey naked.
- Happy has one single and very small, but quite noteworthy example here. While Lucy and aforementioned Erza defeat most of their opponents in the panel in the middle row with normal attacks, Happy apparently defeats his by ripping off his clothes on the lower body.
- Natsu switches quite a lot between this and Chaste Hero. He seems to be a chaste hero by default, but when he gets time to think, he isn't all innocent. Firstly, he's the one to suggest that the guys peep on the girls in a hot spring. Later, he is asked how a distressed Lucy is doing. Natsu replies that she is currently showering and asks if he should check up on her again. The others say that he'd better not, and Natsu initially doesn't understand why (completely missing that it's inappropriate to walk in on the opposite sex in the showers). But when he understands their point, he gets excited and tries to run off to see Lucy naked. Lastly, when a naked Lucy is thrown into him, she desperately asks him to not look at her breasts. Natsu's reaction? He covers her breasts with his hands. It's ambiguous whether he did it on purpose to get a feel or if it was an Innocently Insensitive solution (after all, if he covered her up, he couldn't look at her, and she only asked him to stop looking, not to stop touching).
- Louise of The Familiar of Zero, especially in the light novels. She beats up Saito at the first sign of his pervertedness, yet whenever we are shown her fantasies, it's rather... saucy. At one point she attacks a large crowd for waking her up from a dream of her and Saito that was "just getting to the good part".
- In Gintama, the Shogun is shown to be one when he decides to visit the pool while Gintoki and company are there. He starts quivering when he initially sees the girls, and later gets a massive nosebleed at the thought of them playing a game that would likely result in a Wardrobe Malfunction, all without displaying the slightest bit of emotion.
- Yukinari of Girls Bravo is rather reluctant to be around girls mostly because of how he's been bullied and beat up by girls his whole life. He also gets incredibly nervous when Lisa, who is infatuated with him, constantly tries to abduct and seduce him. However, he got a nosebleed when he saw Miharu in a blouse and panties, and one episode reveals that he keeps porn under his bed.
- In Goshuushou-sama Ninomiya-kun the innocent looking Mayu is actually a Yaoi Fangirl, who writes her own yaoi manga, and Reika can actually be incredibly perverted, which she hides behind a Tsundere facade and hits Shungo if she feels he's acting perverted.
- In the Yuri Genre manga Husky and Medley, Medley is surprised to learn during an after-school encounter in an empty classroom that Husky, who everyone thinks of as the perfect strait-laced schoolgirl, actually has a bit of a dominance kink. After Husky holds Medley up against a wall in an embarrassing position while kissing her, Medley reports to 2ch that "this was the day I became a masochist".
- The Great Guardians saga of Ikki Tousen shows us just how dirty Kanu Unchou's mind really is.
- Chairman Kurihara from Prison School is a elderly man with an always stern expression who also has a fetish for women's butts. Something he tries to hide from his oldest daughter but can't since he keeps spilling his Porn Stash in front of her.
- Karakuridouji Ultimo has Yaoi Fangirl Kiyose, who blushes when she sees her two friends Yamato and Rune together. In Yamato's case, it's annoying, in Rune's case, she was right.
- Both main girls of Kase-san are the type to get extremely flustered over even holding hands with one another, but on multiple occasions it's made very clear that they're attracted to one another, such as when Kase corners Yamada one time and the latter finds herself distracted by Kase's giant boobs.
- Shinobu in Love Hina. Too bad people always point the blame to Keitaro whenever she gets a perverted thought in her head.
- Luca in Macross Frontier looks younger than he really is, so when Sheryl suddenly calls Alto her slave in public, he immediately imagines Alto tied up with Sheryl standing over him in a dominatrix outfit◊. Of course it doesn't help when Sheryl is always Fanservice. It also doesn't help when Luca's crush, Nanase, is the most buxom character on the show.
- Takeo Takakura in Magic Users Club is plagued by his own perverted thoughts, usually directed at his female club members.
- Mahou Sensei Negima!:
- The Expy of Shinobu, Nodoka Miyazaki, a mousy Shrinking Violet who keeps surprising everyone in the cast with her boldness, both as an adventurer and a lovestruck romantic. For example, at one point she discovers that she's stuck in a Love Triangle with her teacher and her best friend Yue. The first solution she comes up with? Have a threesome.
- Oh, Setsuna Sakurazaki. We can let slide the fact that she pulled a Groin Attack on her 10-year-old teacher because she mistook him for an enemy, but not how her "perfect world" as described by then Rainyday sisters' Lotus-Eater Machine includes her crush and charge Konoka in a Naked Apron. And then there's her daydream about her ideal future, where she shares a hotel suite with Konoka, who approaches her while clad only in a Modesty Towel and proposes that it's about time they have a True Pactio (read: sex).
Setsuna: (beating herself up for her overactive imagination) This isn't a future! This is just a delusion! What's wrong with me! This isn't right! I'm bad! I'm perverted!
- Chachamaru, of all people:
Someone: Oh ho? Negi-kun's secretary, eh? Sounds nice.
Chachamaru: (daydreaming) Yes...
Someone: So... he'll wind you up every day?
Chachamaru: (still daydreaming) Yeah...
- One of the few times when this is NOT Played for Laughs due to the context, mainly attempting to rape someone, is Yuri Tokikago from Mawaru-Penguindrum. Before episode 15, who would guess that Yuri would know how to tie someone up in shibari bondage? Or have access to what're essentially roofies?
- Lucia Nanami in Mermaid Melody Pichi Pichi Pitch gets blushy and angry at the more overtly dirty-minded Hanon, but take a look inside her mind...
- Rinko Yamato of My Love Story!! can come off as this, but is ultimately a subversion. She frets about not being as "pure" as Takeo thinks she is because she really wants to be able to hold hands with him, and she considers multiple very risque swimsuits when shopping for a trip to the beach. In the latter case, she is trying to pick something provocative to get Takeo's heart racing, like he so often does to her, but is overcompensating because she feels like she has the body of a little kid next to him.
- Asami of My Wife Is a High School Girl constantly feels frustrated by the fact that she can't get it on with her teacher husband, thanks to her father's forcing The Jail Bait Wait on the couple.
- Neji Hyuga in Naruto is constantly implied by the creators to be this, both in the actual series and in the Rock Lee's Springtime of Youth spin-off. In the spin-off, there is a scene where Neji magically turns into Sakura. When he realizes that, he exclaims I'm an actual girl, now?!, before he pauses, looks under his shirt and drools as his eyes become heart-shaped. Also, in the Road To Ninja alternate movie, he becomes an actual sex maniac.
- Ebisu always berates Naruto for using his Sexy no Jutsu technique (calling it indecent) but is nonetheless consistently "defeated" by it. Naruto even refers to him as a "closet perv".
- When Konohamaru showed off how he had learned the Sexy no Jutsu, Sakura got angry and called him out... but then he showed his "counterattack" by creating a Ho Yay Sexy no Jutsu with naked Sasuke and Sai. Sakura promptly had a nosebleed.
- Neon Genesis Evangelion ; Whether Shinji Ikari is this or actually a shy kid whose sexual repression occasionally lapses is up for interpretation.
- Mio in Nichijou has moments of this. Basically, she is a Yaoi Fangirl and a mangaka trying to keep her interests a secret, but usually letting it slip when Yukko (or a local policeman) get hands on one of her works. Berserk Button ensues.
- Throughout the episodes, she has to chase down Yuuko to get back her notebook after belatedly remembering she had drawn a naughty picture of the guy she likes in it, she gets in a drawing competition with Yuuko and ends up getting carried away. Most recently she ends up attacking a police officer, an old man, Yuuko, and a goat when they all catch sight of her drawings in her desperation to get them back.
- Sakurai Sensei enjoyed one of Mio's drawings, enough that she put it on a test to describe something as "cool".
- Hadzuki from Ojamajo Doremi gets a moment during the Fathers' Day episode of Dokkan!: While Hadzuki, Aiko, and Momoko are helping out at a bathhouse their classmate's family owns, Kotake comes in and strips down without noticing Hadzuki there helping a toddler. After Aiko bursts in to see what the commotion is all about, Kotake storms out in an embarrassed panic, leading to the following exchange:
Aiko: Why is he getting so embarrassed? And now he's going home without taking a bath?
Hadzuki: *grinning* Nothing worth getting embarrassed over. *giggle*
Aiko and Momoko *puzzled look* Huh?
- One Piece: The most straight example in the series is probably Usopp. So far, he's only had one nosebleed in the series (at the end of the Alabasta Arc, although everyone had it (even Luffy and Chopper) so it's not that special anyway.) All the other times he's been showing any sexual interest he usually just blushes and gets over it fast, and he has no problem fighting female villains.
- Yu Narukami a.k.a. the male protagonist in Persona 4: The Animation. In the original game this was more optional since you, as the player, got to choose whether he was a pervert or not; in the anime, however, Narukami makes this face◊ upon seeing Shadow Yukiko in the Midnight Channel, and then says "I wish I had taped it." And later, when Shadow Kanji and his minions have Yukiko and Chie covered in slime, Yosuke asks him if he does have a camera, and he says "Dammit, no!" Then, when Shadow Rise appears on Midnight Channel, he keeps pressing the record button without diverting his eyes from the screen, then becomes disappointed upon realizing that the channel cannot be recorded.
- Tracey from Pokémon has been seen drawing girls he has interest in from time to time. Ash or Misty would usually notice him doing so and tease him, while Tracey reacts nervously.
- In Ranma One Half, perverts tend to be more obvious then anything — Happosai and Tatewaki Kuno most prominently. However, there are subtler displays of perversion. Ukyo Kuonji is normally the most normal-seeming female of the fiancees, with a record that includes slapping Ranma for flashing her breasts to Ryoga and whacking him for calling her cute/asking if she loved him (admittedly, she had been attacking him just before). However, when Genma (in the manga) reveals he has a nude photo of Ranma, Ukyo begs him to let her have it and is shown practically drooling over what she can see of it.
- While whether he has perverse intentions or not is endlessly fought over, Ryoga Hibiki is a more literal interpretation of this, in that his P-chan form allows him to be taken to Akane's bed, fed off her plate, held in her lap, cuddled to her breasts and even kissed on the nose by her at least once. All without her having any idea that Ryoga and her pet pig are the same being.
- Speaking of Akane, for being such a prudish girl who freaks out at the mere sight of a naked man, she is also the quickest person of the cast to see the perverted potential in just about any whacky set of hijinks. Especially if it involves Ranma. A first-rate example is when Kuno was about to ask for a wish to a magical rock: while she and Ranma discussed it, Akane imagined Kuno asking for female!Ranma to love him, and immediately came up with the Imagine Spot of Kuno taking advantage of this to rape Ranko on the spot. She ends up giving a Big "NO!".
- Nori in Rozen Maiden is a gracious, kind older sister to the horribly antisocial protagonist Jun. You'd think she's just patient, but she also talks in her sleep, and says some really odd things.
- The otherwise motherly and elegant Cherry in Saber Marionette J fell victim to these, with her embellished daydreams about Otaru becoming increasingly lewd over time, sometimes ending in an ecstatic pile of squee right in front of a very confused and creeped-out Otaru. Hanagata did the same towards Otaru and at least once in Saber Marionette J Again, Luchs did towards Faust.
- Ami Mizuno/Mercury in Sailor Moon sometimes has shades of this, with the excuse that she really is the smartest of all the girls. Despite horrible reactions to love letters, she was worldly enough to assume alien-turned-villain Fiore was actually attracted to Usagi's boyfriend. The joke gained more fodder with the introduction of Haruka and Michiru, where Ami is the only character not completely unfazed by the situation and quite frankly understands the nature of their relationship. Similarly, a much later gag from Stars with a handsome young man and a short towel has all the girls shocked... save Ami, who seems to be peeking between her face-covering hands. And let's not forget she's got very exclusive Starlight fan stuff that the other girls (much more open Starlight fangirls) don't...
- There's also an episode in the first series in which Usagi and Mamoru are babysitting, and the rest of the Senshi are jokingly asking when they had a baby. Ami's reaction is a smirk and, "What did you and Mamoru do?"
- Rei Hino/Mars is one too. In the anime, she's in possession of rather saucy mangas, magazines and doujinshis involving Crossdressers and is very flustered when Usagi finds them.
- Nanami in The Pet Girl of Sakurasou may look relatively normal (if not a bit workaholic), but she owns some rather fancy underwear, and her usual reaction whenever confronted by a strange situation is to assume the most perverted possibility.
- Haruki Hanai from School Rumble tries his best to be a very moral and strict character, but he is human with his own perverted moments and thoughts.
- Seitokai Yakuindomo works on Vulgar Humour, so this trait is commonplace—especially given the examples do maintain an exterior of propriety for an efficient student council.
- Most girls in the cast, bar Suzu, Mutsumi, Kaede, and Toki, are of this nature.
- Not even Mutsumi's immune to it. In one gag, she's just returned from judo practice and is sweating profusely when Takatoshi asks her for help hanging something on the wall, requiring her to get close to him. When she blushes and says that she can't because she's covered in sweat, Takatoshi says he doesn't mind. Her eyes instantly light up and she excitedly asks "is that your feitsh?!"
- Kaede, for all her prudishness, she immediately mistakes a perfectly innocent discussion on sleeping posture in chapter 120 as proof that the student council knows each other's sleeping postures because they have slept together. Shino and Aria call her out on this.
- The One Guy Takatoshi also has this, but far downplayed. This is evident in the end of Chapter 102, where he says "Hey, you'll get me excited" when Shino asks to spank his butt since she can't clap her hands while holding something. He's also sometimes agreed with or didn't deny when the girls have called him a masochist.
- Mafuyu from Seitokai no Ichizon. She has a shy personality and looks innocent but she is a huge yaoi fangirl who fantasizes pairing Ken romantically with a boy named Nakameguro. In fact, when it comes to yaoi, Mafuyu can actually be just as perverted, if not worse, than Ken.
- Momoka Nishizawa from Sgt. Frog may be one. When Mois gets "scary story" (kwaidan) mixed up with "dirty story" (waidan) in one chapter, Fuyuki and Natsumi listen to her story red-faced, too embarrassed to comment. Momoka's blushing too, but is also listening intently, and even tells her "Yes, yes, go on!" In another chapter, Momoka tries to get Fuyuki to indulge in some Intimate Healing, much to the delight of her "dark side".
Dark!Momoka: This isn't just a confession... you're gonna skip straight to @#$%! Go, Momoka!
- Akina Shinozaki of Shinozaki-san Ki wo Ota Shika ni! is not only highly prone to fantasies about her friend Kaede, she's also far more into yuri doujinshi than she would like to admit.
- Almost the entire cast of Shokugeki no Soma fits here. The dishes in this series are literally Orgasmically Delicious and everyone who has this kind of "foodgasm" imagines the taste in a sexual way. This is very blatant because only adults and teenagers have this kind of reaction, but not children.
- Star Driver's Wako is one — or at least would be if her imagination wasn't on display for everyone to see.
- Makise Kurisu of Steins;Gate picks up on Daru's innuendos, which he the points out each time much to her embarrassment.
- Yoshika from Strike Witches develops a thing for big breasts, probably because she practically becomes surrounded by an amazon brigade consisting of scantily clad, buxom young ladies?her best friend first and foremost. Of course there is nothing wrong with that in and of itself, but Yoshika tends to act on her attraction at the most awkward moments.
- Kurose of Ten Count is a calm and reserved person...except when he's not.
- To Love-Ru
- Yuuki Rito is one, which a bit of a surprise considering he is Allergic to Love to a small degree. First it began with the few and far between Imagine Spots centered solely around Haruna, before branching out a bit to include others. By Darkness he seems to be strangely fine with the 'Harem Plan' and dreaming of naked girls in the bath.
- Yui Kotegawa also qualifies. She protests Rito's Accidental Pervert moments a little too vigorously, and she's the one non-overtly-perverted cast member who's receptive of Rito's attention, much as she's loathe to admit it.
- Haruna. One chapter of Darkness has her fantasizing about Rito bathing her. And by "bathing" we mean heavy petting with sexual undertones.
- Mirei Shizuoka of Kenko Zenrakei Suieibu Umisho is viewed by her peers as being pure, innocent and shy. Yet she wears lingerie that's extremely sexy beneath her clothes, has expressed interest in seeing the bodies of her male team-mates on the swimming team, once suspected Kaname and Amuro of doing This and That, and has expressed interest in buying a large, phallic antique.
- Yugi from Yu-Gi-Oh! is normally a sweet and innocent kid, but in the very first chapter he fantasizes about getting a look up Anzu's skirt, and in a later chapter he blushes hotly when he sees Anzu in a bikini, and is stunned for the next few panels. He also trades pixilated porn videos with Jonouchi.
- To someone who didn't know better, Yuria of Yuria 100 Shiki would appear to be a Covert Pervert. In fact, she is a Ridiculously Human Robot specifically programmed to be such and one of her features is she will instantly imagine the indecent side of anything.
- Ken Nakajima from Youre Under Arrest. So much that he's nicknamed "Mr. Nosebleed" by one of his co-workers.
- The normally Chaste Hero Link has shades of this in a manga adaptation of Zelda II The Adventure Of Link. When a spirit guide Zelda tells him that he can use magic, his first thought is using it to remove her clothes.
- Advice And Trust: After hooking up with Shinji and especially after Their First Time Asuka becomes sex-crazed and gets frustrated if she has not sex with Shinji every day... but in public she still pretends she is not interested in sex so that nobody suspects they are together. When someone figures out they are together and finds out what kind of thoughts she has they are shocked because they did not think she could be so lewd.
- During the Chunin Exams, Hinata was sitting next to Naruto in A Growing Affection. It turns out she tried looking at his test to check on him, but also because he kept fidgeting and she caught a glimpse of...something else.
- Naruto becomes this in Escape From The Hokage's Hat. Due in part to having had a seal placed on him (multiple actually but just explaining this one is important for now) that screwed with his libido and hormones but was removed forcing the 13 year old to just deal with the overload. Naruto then travels in a group with Hinata, Shizune and Tsunade. Cue Naruto suddenly thinking about how bad he wants a backrub from Shizune, wants a hug (Marshmallow Hell) from Tsunade, comments on how he wants to "hold Hinata and never let her go" and suddenly be turned on by Hinata's laugh.
- Nagato and Hanyuu are this in Kyon Big Damn Hero, spending part of the time when they were watching Kyon 'enjoying the view'.
- Michael in The Prayer Warriors is a fundamentalist Christian who considers men and women so much as getting within a foot of each other out of wedlock to be sinful, but he admits to finding Ginny "pretty hot" while he is infiltrating Hogwarts in Battle With the Witches. He then puts those thoughts out of his head and gets outraged when Ebony puts her hand on him.
- Sunny Breeze in Racer and the Geek behaves like this, although he adamantly denies having any sort of sexual feelings or attraction. It's definitely not the case.
- The Second Try: Shinji is peacefully watching Asuka breastfeed their child. She sees him looking at her and asks if he's jealous and wants a taste (Character Development, a resolving of their Unresolved Sexual Tension and marriage and a child with Shinji has made her stop being a Tsundere). Shinji said it best:
"You know, for someone who kept calling me a pervert... you have some very interesting thoughts."
- More than one My Little Pony: Friendship Is Magic fanfic has Fluttershy as the author of saucy novels (as being an animal caretaker doesn't pay the bills). One particularly blatant example is Do You Really Want to Know?, in which Twilight Sparkle and Princess Celestia discover a series of miscommunications is due to a draft of one of Fluttershy's stories getting attached to one of Twilight's friendship reports. Celestia immediately wonders why Fluttershy was writing a slashfic involving her and all her friends. With illustrations. Twilight asks if they really want to know, and Celestia replies that no, they really don't. Princess Luna does.
- Twilight Sparkle is a frequent recipient of this trope in fanfiction too. Romance Reports for example has Twilight take to researching love and sex with gusto, having very little hesitation to the idea of having sex with the first willing ponies she can find For Science! (which isn't even what she was told, just an idea she made up herself), and at one point casually invents the pony version of the Kinsey scale.
- In Thanks Kyubey, Madoka has some interesting thoughts on whether the undead aspect of being a Magical Girl is a curse or a blessing.
Madoka: But if you become a magical girl, you can handle rough play and you won't ever get old, right? Isn't that the ideal wife?
- Much Touhou fanon involves Patchouli owning a truly gargantuan collection of erotica in her library. In Touhou: a Glimmer of an Outside World, Koakuma likes to read it, too.
- A new world: Story of a lost Shinobi: Naruto natch. Surprisingly Mirajane whenever Naruto is around. Naruto is rather happy about this since the only other girls he's dealt with are a Shrinking Violet (Hinata) and a often angry Tsundere (Sakura).
Naruto: "So you can get it (Fairy Tail mark) anywhere?"Mirajane: "Yeah. I'd show you mine but that would be a lot of dress to hike up."Naruto: (Spit Take)Mirajane: "I heard some even get it on their butts."Naruto: (pictures Fairy Tail mark on Mirajane's butt)Mirajane: (playful Dope Slap followed by a smile) "You better not be thinking what I think you're thinking or I won't feed you."Mirajane: "You know I'm occasionally the cover girl for Sorcerer Weekly. They have a lot of pictures of me."Naruto: (Fascinating Eyebrow) "Really? Where can I find these magazines?"Mirajane: (stretches flirtatiously) "Why would you want you want the magazines when the cover girl is right in front of you?"Naruto: "You got a point. But with the pictures I could stare at them as long as I want without being called a pervert."Mirajane: "I never said I'd call you that."
- In A Snowflake In Spring, Elsa's mutism and her Moe-ness around Anna make it easy for the latter - and the audience - to think of her as an innocent child. Elsa, however, is an eighteen-year-old girl who has read some rather "risqué" books and who rarely misses the opportunity to cast... appreciative glances at Anna. The contrast is made especially apparent when the story switches to Elsa's perspective.
- Ginchiyo, of Graduate Meeting Of Mutual Killing, was a nice woman who hadn't shown any kind of lewd thoughts of behavior towards anybody. However, when a body search on what is implied to be her love interest (which seems mutual), she instantly jumped into the chance to grope him all over. It reached a point where Akane Ogata, who was restraining the person being searched, reprimanded her to control her lust.
- An omake in the Bleach fanfic Chasing the Moon reveals that Yuzu sneaked a peek at Byakuya when they were Hanging Their Clothes To Dry. In her defense, it would be pretty tempting.
- In The Uzumaki Tales: Return of the Whirlpool, Jiraiya calls the Hyuga clan "the biggest closet perverts in all of Konoha," mainly because of the Byakugan. As he points out, their compound is one kilometer away from the hot springs in Konoha, far enough not to put up any flags, but close enough in order to take advantage of their... gift. It's also shown that Jiraiya is the one who turned the young and still innocent Hiashi into this after teaching him the... advantages of the Byakugan.
- In Sekirei? Is that some new species of little sister?, Akitsu is shown to be a huge pervert but doesn't show it much due to being both The Stoic and The Quiet One. When she tells Takami that Naruto and his wife chain her up and spank her, Naruto replies that Akitsu failed to mention she likes both even more than he does.
- In Adventurers and Adversaries: Hellmouth Edition, Xander Willow and Buffy get sucked into a Dungeons and Dragons style game. At one point Buffy accidentally uses the last wish on an enchanted sword to gain the power to create underwear with a snap of her fingers. The catch? She has to know the measurements of whoever she creates them for, leading to Buffy groping Willow. Buffy's quite put out that Xander finds pants before she can grope him.
- In Meduka Meguca, the stoic, cynical Homura uses her time-freezing powers to take advantage of her Love Interest.
- In Off The Line while Vincent keeps a straight face and for the most part his affection for Cloud/Rainstorm is kept chaste, but he definitely is affected by always having to be near a Shameless Fanservice Guy. In his own thoughts, he expresses the desire to touch Rainstorm more intimately.
- Setting The Bar is- for good reason- the only Steven Universe fic in which Pearl works as a pimp.
Amethyst: Who knew the little prude had it in her?
- Kitsune no Ken: Fist of the Fox: Itachi, of all people. On one occasion when Ino gropes Hinata's breasts from behind while demanding to know Hinata's secret, Itachi's response is to start taking pictures with his cell-phone. And prior to that, Yugito accuses him of perversion when he wonders aloud and with a little too much interest what Hinata's reaction was to accidentally seeing Yugito naked in a Waterfall Shower, moments after Yugito informs him of the incident.
Yugito: No, Itachi, she did not take off her clothes and offer to join me. Pervert.
Film - Animated
- The Hunchback of Notre Dame: Judge Claude Frollo might qualify as this, given how he hides his lustful thoughts behind a self-righteous demeanor. He might alternatively qualify as a subversion, though, given how Esmeralda sees right through him. Consider the scene where he sniffs her hair.
Esmeralda: What are you doing?Frollo: I was just imagining a rope around that beautiful neck.Esmeralda: I know what you're imagining.Frollo: ... such a clever witch. So typical of your kind to twist the truth, to cloud the mind with unholy thoughts.
- Kung Fu Panda: When Tigress performs a split kick in the air and destroys two wooden boards, Po is seen having a Nerdgasm and staring at her ass when she lands.
Film - Live Action
- Michelle in the first American Pie film, who comes off as dorky and awkward until the Wham Line that shows that she most definitely isn't.
- In the S Club 7 movie Seeing Double the band kidnap their dim-witted clones and tie them up. The Rachel clone wonders if it's part of their training program and asks "Do I tie you up now, Bradley?". Bradley gets quite hot under the collar and says "we'll talk about it later".
- Later on we find out that the clones are taught to shower together to save water, so the fun starts when Bradley is showering in the garden and the Rachel and Hannah clones climb in with him. He heads for the hills when the Jon clone climbs in too but Tina sneaks a peek at them.
- In A Brother's Price Cullen Moorland is somewhere between this and a true innocent. He's very interested in the pornographic pictures his cousin Lylia gives him, but when he's sharing them with Jerin, he comments at one point:
"Why would anyone want to put his mouth there?"
- Jerin himself has been told about the "paths of pleasure" by his grandfather, and could explain a thing or two to Cullen, but as everyone expects him to remain chaste until marriage, he can't tell that he in fact recognizes the depicted scene as something he did and enjoyed. It's a setting that enforces this trope in men.
- In the book Behaving Bradley, a high school boy gets nicknamed "Microdick" after the other boys see him putting his bathing suit on in the locker room. Hopie, a sweet, naive girl, asks the main character what the nickname means, and he tells her it's because the boy wants to be a disc jockey and use a microphone. She responds "Oh, I thought it was something about his penis."
- War of the Dreaming: Wendy Varovitch.
- The Longing of Shiina Ryo: Shin-tsu, oh so very much.
- As revealed in Harry Potter and the Goblet of Fire, Moaning Myrtle "sometimes" sneaks into the prefects' bathroom to watch them bathe. Harry finds this out while taking a bath himself to figure out a tournament clue that's only comprehensible underwater.
- In the Discworld book Carpe Jugulum, Dirty Old Woman Nanny Ogg is rendered speechless when the formerly naïve Magrat Garlick caps her with a perfect double entendre.
"Oh, I don't know, I really don't," said Nanny. "I mean, it's flattering and everything, but I really don't think I could be goin' out with a man with a limp."
Live Action TV
- In Smallville, Jimmy Olsen apparently likes BDSM.
Lois: (finds a pair of fluffy pink handcuffs) Guess the Olsen's not so wholesome.
- It seems that Chloe Sullivan is perfectly fine with that. Combining that to her losing her virginity when she was underage in a very short romance and having a casually sexual relationship with Oliver two episodes after the first hint of attraction, maybe the fans favourite sweet girl isn't that innocent after all...
- Buffy the Vampire Slayer
"Oh, right. Me and Oz play "Mistress Of Pain" every night""Did anyone else go to a scary visual place?"
- Occasional hints are given that Willow is one, like her "everyone's getting spanked but me" comment, and the accidental ogling of Dawn (the Dawn part was the accident, not the ogling) that one time.
- Her girlfriend Tara seems to be the same.
- Buffy's no slouch either. She's the aggressor in each of her relationships, she's into femdom if Spike is anything to go by, in the series finale she said he and Angel might do oil wrestling and the comics...the comics has her missing the sex before her deepest fantasy is revealed. That fantasy is her playing mistress chained to a naked Angel and Spike, wearing a Naughty Nurse Outfit. It's been a slow year. Also, when hit with a love spell she tries stripping for Xander.
- This is the most obvious character trait of Tobias from Arrested Development, who never seems to consciously think or care about sex at all.
- There's a rather startling scene in Pushing Daisies where Chuck, in an attempt to prove that she's not as sheltered as she seems, talks about her aunt's collection of erotica.
- Mindy from Mork and Mindy. In the pilot, she asks Mork to test his voice by reading from a book she has. Turns out it's a steamy romance novel. And later in the series when it's revealed that Orkan ears unscrew, she says "Gee, I'm afraid of what else comes off!".
- Phoebe from Friends was initially like this before they used it so much that it became less covert and more just part of her character that she was the kinky, frequently sharp tongued and kind of mean, one.
- Rachel and Emma from Glee. "Push it" was Rachel's idea and Emma informs Rachel that someday not having a gag reflex will be a gift. If you know what she means.
- Though Firefly has plenty of characters with overt sexuality, the last place one would expect to see such sexual commentary from is the somewhat unhinged yet innocent River; nonetheless she gets in the occasional comment that makes it very clear she's paying attention. In the comic Those Left Behind, Wash and Zoe make love on the bridge, and then suddenly have to call everyone else up to the bridge when they find something important. No one says anything as the two are straightening out their clothes... until River blurts out "It stinks like sex in here." In Serenity at the very end, when Kaylee and Simon are, well, taking the "unresolved" out of their Unresolved Sexual Tension, River is seen spying on them from above with a curious look on her face. For bonus points, Simon's her brother. River doesn't hesitate to bait Jayne into chatting about his "man-parts" - and it doesn't seem to bother her when he does, either. And her "cockney come-on" to Badger.
- Doctor Who
- The episode "Amy's Choice" hints the 11th Doctor might be the darker side of this trope.
- In "The Angels Take Manhattan", the Doctor is reading a trashy detective novel. He doesn't seem to be entirely aware that he's reading it out loud and saying "yowza!" to the descriptions of the Femme Fatale detective's impressive cleavage. Later in the episode, it's mentioned that he has "the face of a twelve-year-old". Becomes funnier after the reveal that the Femme Fatale is actually River. Who is his wife!
- On a much lighter note, Rory, if the 2011 Red Nose Day short is anything to go by. He responded quite well to the sight of his wife flirting with herself from the future. Also, the reason everything went wrong in that episode was Amy's fault. Rory was helping the Doctor fix the TARDIS and Amy was wearing a skirt. On a glass floor. Under which was Rory. Rory did apologize, for what it's worth (for dropping whatever he was holding, not for peeking.)
- The Tenth Doctor once remarked that a "solid leather" slave drone rather suggested that "someone's got one hell of a fetish."
- The episode "Amy's Choice" hints the 11th Doctor might be the darker side of this trope.
- Many instances of Annie on Community doing this. Most noticeably in her stint as Hector the Well Endowed, a D & D chracter, who has to seduce a elf maiden. Troy is seen taking notes as she describes her actions.
- Dr Chi Park on House. Comes across as mousey and repressed, 95 per cent of the time. The other five per cent she's accusing Dr Adams of wanting to masturbate over her, or casually claiming to have had sex with over thirty guys (which she then admits is a lie; whether the true figure is higher or lower remains unknown).
- Lily in How I Met Your Mother is, if anything, even more perverted than Barney. When he describes something that he claims happened she knows exactly what porno the scene he made up is from. Of course, it's Alyson Hannigan here.
- Star Trek: Voyager. It may be just scientific curiosity, but when Q is about to get it on with a female member of his species, Captain Janeway suggests giving them some privacy.
Q: What's wrong, Kathy? Don't you like to watch?
(Janeway looks indignant, then when Q turns to Ms Q sneaks close with an eager expression. The two Q's touch fingers and shiver in delight)
Janeway: That was it?!!
Q: You had your chance. Don't go crying about it now.
- Kate Beckett from Castle is implied to have some of this in her past. In one episode, Castle was left wondering how she knew so much about hand-made bondage cuffs. Then there's this thing she does with ice cubes...
- Major Margaret "Hotlips" Houlihan is a variant of this Played for Laughs in the early seasons of MASH; she feigns being a prim, proper woman, but is actually a lustful, passionate woman who has frequent moments of Casual Kink with her steady lover, the already-married Jerkass Doctor Major Frank Burns, and is implied to have slept with almost every Major or higher-ranked guest Official who shows up.
- A rare non-comedic example of this trope is James in Silent Hill 2, who initially appears to be a relatively normal (if rather dense and insensitive) individual until it's revealed the majority of the twisted abominations (most of whom are conspicuously feminine and sexualized) that have been attacking him over the course of the game are the personifications of his sexual repression and frustration.
- Taokaka of Blazblue is a childish, innocent-seeming catgirl who's mostly interested in helping her village and eating — she even sometimes calls characters by cute, childish nicknames, like referring to Nu-13 as the "flappy thing" and Litchi as "Boobie Lady". Except that it later becomes obvious from further dialogue that "Boobie Lady" is not simply a cute nickname based on
onetwo of Litchi's distinguishing features, but that she's downright obsessed with breasts in a seemingly fetishistic way... as seen at one point with the poor 'Average' Tsubaki.
- When Bang is on the end of a mistaken Skinship Grope from Tao, his reaction suggests him to be one of these as well. And then there's that dream he had in "Teach Me, Miss Litchi"...
- Noel also counts. Even though she's a go-to example for Shrinking Violet, she's demonstrated to be much more knowledgeable about sexual relationships than Jin, and she's much younger than he is. Much, much younger than he is, as it turns out. There's also a scene wherein she (briefly) contemplates second base because she heard from Makoto that her breasts will get bigger if a boy massages them. Come to think of it, hanging around Makoto - a Ms. Fanservice who is absolutely not subtle about her perverted tendencies - is probably where she gets this trait from.
- Fia from Riviera: The Promised Land.
- Dragon Age:
Josephine: Who wouldn't be a little curious?
- Dragon Age: Origins has Alistair, a nice young man who was raised as a templar and thus is a virgin, is quite reluctant at the idea of sex (waiting for the moment to do it). If you try to romance both him and Leliana, he'll describe the latter as "hot" and even if you don't harden him, will comment "and here I am, awake and everything..." if your character goes have sex with Pirate Girl Isabella.
- Leliana is meant to be a cloistered sister, and while genuine it's also to mask that she was a gay ninja spy. She gets jealous of Isabela offering herself to the Warden and depending on the playthrough chooses to invite herself along, with Isabela commenting on her performance and Leliana explaining just where she picked up what she learned, can be pretty Aggressive Submissive even if a Warden actively ignores or avoids a romance and drops several not so subtle hints that she wants you, race or gender irrelevant.
- Dragon Age II:
Bethany: So you've... been with women? In bed?
- Merrill. Normally, her not understanding innuendo is a Running Gag in the game, but at one point Anders catches her digging through his spellbooks, looking for 'dirty' spells. She also misses the qunari because they were "easy on the eyes"...
- Bethany. A devout Andrastian, and quite innocent and inexperienced in life due to her sheltered upbringing. Nonetheless, she shows interest in Isabela's talk about sex (even if she tries to repress these urges at first), before fully embracing it when she's sent off to the Circle, where she enjoys all the suggestive books Isabela sends her.
Isabela: Shocking, isn't it? You see, sweetness, men are only good for one thing. Women are good for six.
Bethany: Six? (hesitantly) ... which six?note
- Josephine in Dragon Age: Inquisition, though ironically not if the player is romancing her. When she walks in on the aftermath of The Iron Bull and the player character consummating their relationship her reaction compared to Cullen and Cassandra (who are respectively trying not to look and obviously startled) is priceless.
(Cullen and Cassandra look at her)
- Cassandra is a fan of a romance serial written by Varric, outright calling it "smutty literature".
- Diving deep into the heroines' Cosmos Spheres in the Ar tonelico series reveals their "true" personalities, thoughts, and desires under the masks of being pure, shy, cute, bossy, hotheaded, or whatever in the real world. Given how they present the games, Those heroines have... a lot of unhealthy suggestive things in their minds.
- The first game gives us Aurica who is normally very soft spoken and unsure of herself. In the latter half of her Cosmosphere, she kidnaps Lyner, ties him to the bed, straddles him and electrocutes him when he tries to run, all while wearing nothing more than a towel. Apparently this is so dangerous that an incarnation of the good in Aurica's mind appears to save Lyner and that level of the Cosmosphere is entirely abandoned with dangerous consequences later.
- In Persona 3 Portable, if Akihiko becomes the Female Protagonist's Love Interest, he shows some signs of this. Despite being almost completely Oblivious to Love, when you go up to his room a second time, he's quite eager to "let [their] bodies do the talking".
- From Persona 4, Yukiko Amagi. Normally rather shy and reserved, not to mention the low tolerance she has for what she perceives as, in her somewhat ditzy mindset, lecherous behavior. Once she gets drunk, however, or at least believes she does, her inhibitions fly out of the window. Also, if you are in a relationship with her, she's more than happy to dress up in one of the sexier alternative costumes. She would prefer it to be in private, though, instead of in front of the whole group.
- The "perfect lady" Nera Briscoletti from Dragon Quest V sometimes make an outright sex joke during a party chat.
- At one point in Kid Icarus: Uprising, Palutena mentions she could read Pit's mind, telling him he'd better not be thinking anything naughty. Pit seems rather defensive and quick to react, even giving a Suspiciously Specific Denial when Palutena tells him it was a joke.
- There is a hot springs scene where (in the Japanese version anyway) she practically begs Pit to take off his clothes.
- Mass Effect:
- Kasumi Goto of Mass Effect 2 uses her cloaking skills to watch Jacob, and hints at watching Shepard with their love interest. During the actual, well, scene, given how accurate her comments are. Taken to truly Up to Eleven levels in the Citadel DLC where she is a classier mix of Matriarch Aethyta and Mel the "Infiltrator Tits, imagine the kinkiest thing you can and hang a Hanar off it" marine. She can also be found at one point rummaging around in Shepard's underwear drawer, which occurs with both genders.
- Also in Mass Effect 2, Shepard's Quarian friend from the first game, Tali'Zorah, is shown in the Shadow Broker's files to have installed a certain nerve-stimulation program into her environment suit several times, eventually settling on the deluxe edition right after downloading an educational video about human courtship and mating. As Tali is a romance option for male Shepard and has a massive crush on him, one can assume that he is the reason for these activities. All those downloads still occur if Shepard is a woman.
- In Mass Effect 3, there are hints that the shy and socially awkward Samantha Traynor is this, for example when she boldly attempts to seduce a female Shepard when given the chance. The Citadel DLC takes away all doubts, revealing that she fantasizes about EDI—or at least her voice—and she shows interest in EDI's list of extranet sites that basically amount to lesbian organic on synthetic porn.
- Given that Protheans have empathic abilities allowing them to view others memories, Javik has some unique dialogue for a Male Shepard romancing Tali, in which he implies that he might have witnessed a few intimate scenes whilst he read their DNA.
- Kaidan Alenko comes off as prudish at first, even turning down the offer of a threesome with FemShep and Liara, but gives a rather infamous response to the mention of how young men were affected by the sight of Liara's mother in a pinstripe suit. ("It does sound like something that you'd find on an extranet fetish site." (beat) "What?") This is played up even more in the third game.
- Of all characters in Fire Emblem Awakening, the very serious and straightlaced Laurent seems to be this. In his and Noire's S support, it look like he's a masochist, expressing excitement over one of his girlfriend-to-be's Split Personality outbursts. Even said prospect girlfriend is all "what the...?!"
- If you build supports between Lon'qu and Maribelle, she will learn about his Cannot Talk to Women problem. Her suggested solution is to send him "to an establishment where a pack of lovely ladies wait on you". And then she's offended when Lon'qu is all "... where did you learn THAT?!"
- Sumia is one of these too. If you make her build supports with Frederick enough to get a Love Confession, when he says he doesn't have eyes for anyone but her she giggles and asks "what about Chrom?!" before accepting. And then there's how she tries to rope Sully into a crossdressing pageant in the Harvest Scramble DLC...
- Tales of Destiny: Stahn is usually the innocent Nice Guy of the party, but the first thing he does after accidentally switching bodies with Philia is wonder how soft her breasts are.
- From Tales of Xillia we have Jude edging ever so slowly to Milla before backing away with a blush saying that she looks like a regular woman. There's also Elize, who's living doll moterboats Milla. Elize's doll has no mind of his own. He just voices and acts on Elize's innermost thoughts.
- The Duchess in Embric of Wulfhammer's Castle starts off as this, desperately trying to maintain her Proper Lady persona in the face of while all the situations that conspire to rid her of her dress are annoying, some of them are also pretty fun (except for constantly being tied up; she always hates that). Most of the routes have her abandon it though, particularly the ones that have her embrace the "Dark Duchess" persona, while another ending has her get most of the ladies in a Duchess-centric orgy.
- While Dominic of Roommates is normally straight-laced and condemns both Max and Isabella, if Anne chooses to peep on him in the bathroom, it raises his affection for her.
- Super Robot Wars Z: Despite being a serious minded individual and a stoic, Hibiki Kamishiro joins Kurz and Boss's gang as they attempt peep at the girls hot springs by going up other side of the mountain filled by booby traps.
- The Handmaiden in Knights of the Old Republic II: The Sith Lords is accused of this, but it is left ambiguous how true it is — she is presented as an Innocent Fanservice Girl who asks to spar in underwear simply because that's how Echani training usually is and can be convinced to wear clothing with a practical argument, but this can later come up in conversation with another character with some familiarity with Echani customs. He claims that while the Echani do indeed have semi-nude sparring as training, it's a somewhat intimate thing not done until you have grown familiar with the one you are doing it with. Now why might the Handmaiden have wanted to go directly to that stage...
- Little Busters! has Nishizono Mio, who, upon being invited by Riki to be the manager for their baseball team, more than happily fills in the blanks with her mind when Riki fails to mention the "baseball" part quickly enough. Then there's the part where she sees Riki and Kyousuke acting very touchy and mistakes them for gay. Or later when she presses him for information about their childhood together and sighs dreamily... It's not just yaoi, either - one of her sayings after being given a nickname for losing a battle is "Is this some kind of SM thing? You have strange fetishes..."
- And when the six girls have a Slumber Party and decide to drag Riki over to participate... Yeah.
- To a lesser extent, Haruka. First we have the famous scene where Haruka invites Riki to fix a bench with her using some very particularly-chosen words. Later, when Riki accidentally slips over on a magazine and lands with his hand on her chest, instead of being angry, she murmurs 'It's okay, Riki-kun...' with a blush. (Though they are basically dating by that point) And in the anime, when Kurugaya accuses Riki of bringing the girls into the school at night so he can do This and That with them, if you look at Haruka she's pulling a pretty serious smirk◊.
- Lilly Satou from Katawa Shoujo has a "healthy adolescent sex drive", which involves anything from light bondage to exhibitionism. Who saw that coming?
- Touko Fukawa from Danganronpa, at least to "Byakuya-sama." She often mentions him belittling her with a rather...peculiar facial expression... As the story goes on, however, she gets less and less... covert.
- Kareha from SHUFFLE!. Only covert in that she doesn't say out loud what she's imagining. However, whenever a situation that could be construed as romantic or perverted presents itself, she will Squee and glow.
- Erika from Umineko: When They Cry may appear as an elegant − if slightly insane − miss detective, but she has some very… special fetishes, be it chopsticks, licking her master's empty teapots, or some of her reactions while being punished by said master. Her pervert side is played in a very dark way during her "wedding" with Battler though.
- Nayuta, the prim, proper, cold Student Council President from Yumina The Ethereal seems to get turned on by the thought of people watching her having sex. She doesn't stop your H-scene with her even after her imagination causes her and Ayumu's sexual act to appear on a big-screen TV in their school gym.
- Hatoful Boyfriend's darker "Bad Boys Love" route has a scene in which Sakuya attributes Yuuya's hacking skills to pirating porn. Yuuya is the resident Chivalrous Pervert, so no fowl here... until Ryouta, the innocent childhood friend, wonders what porn Yuuya's watching that taught him this, and decides that he needs to get some of that.
- Played for drama in Fate/stay night. Sakura Matou, due to the side effects of some horrific magical body modifications, gets sexually aroused very easily. That would just be mildly embarrassing on its own, specially for a shy and quiet girl like her, but when you factor in that her adoptive brother Shinji has been raping her daily for years, you can understand why she's dreadfully ashamed.
- Yumiko in Grisaia no Kajitsu at first seems like the most modest and reserved of the girls, but she actually has the most knowledge in the group about sex and spends a lot of nights looking up porn online.
- In True Love Junai Monogatari, the very sweet and naive Miyuki Tanaka is revealed to be this if the player pursues her route. Specially when she asks the MC to put on a swimsuit when she gets ready to draw him, and is disappointed when he puts on a normal one — she pretty much tells him to put a speedo instead.
- A rare male example: Onii-chan from Tsunami Channel has shown hints of secretly being a little more "hentai" than he usually acts.
- Alex/Murfs of Khaos Komix always blushes around his love interest Tom. In the other characters' stories, the impression is that he's blushing because he's shy and embarrassed about his attraction to Tom. In Alex's own story, however, it's revealed that his constant blushing is due to the incredibly dirty thoughts he has about what exactly he'd like to do with Tom.
- Justin, of El Goonish Shive, of all the main characters, is the first to wonder if using a Transformation gun on a female results in a male form with generous... er... gentlemanly parts. He was gender-bent at the time, but it was still unexpected.
- From Homestuck, Rose sure seemed excited about Karkat's trashy romance novel, and gleefully grabs it away from him.
- Likewise, Karkat seems mainly focused on the emotional side of relationships...until Jade begins interacting with Jadesprite, prompting a very distracting (to him) mental image of the two making out.
- In Bittersweet Candy Bowl, Blur shows some tendencies towards this with Mike and Lucy.
- The Law of Purple: Guess what word makes Danni wake up?
- Questionable Content: Hannelore isn't so much "covert" as she is "severely dysfunctional". Nonetheless, it's played off like this trope when she learns from Marigold what "yaoi" is, getting several gigabytes worth of sexy fireman pictures or gets caught peeking at Dora's collection of... "party favors".
- "AAUGH!" *beat panel* "... how does the purple one work?"
- Mild-mannered gamer geek Dale tested an AI virtual companion service... which dressed the companion as a skimpy Meido based on his internet history. He also apparently owns the entire series of Magical Love Gentlemen (the aforementioned yaoi series Marigold showed to Hannelore).
- Seymour on Sinfest has his moments. Especially when a schoolgirl outfit is mentioned, courtesy of Nique.
- Far Out There: Jenna, of all people, would seem to qualify.
- Magical 12th Graders: Aran, one of the Magical Girls, insists that her (male) biology teacher continue dressing as a magical girl simply because she thinks it's the hottest thing ever.
- Didi from Bomango. It was once revealed that she watched hetai and found tentacles "fascinating" much to her embarrassment. She dressed like a Sexy Catgirl on Halloween which seems normal enough... until you realize that she is holding a whip and not a fake tail and just said she doesn't want a Halloween party hosted at her house because she had "plans."
- Tower of God: Yuri Zahard lusts over Baam to the extent that she gets hilarious Nosebleeds even five years after his assumed death.
- Ruby of Sticky Dilly Buns is something of a textbook case, except that the truth is made explicit to the readers from early on. She enters the comic as a sort of Sour Prude/deconstructed Ingenue, but rapidly discovers a new side to her personality (in a comic that is, after all, a Sex Comedy).
- She's not only easily distracted by the gay male activity that keeps happening around her, she has a tendency to think about men in homosexual scenarios and then deny to herself that she's interested, or mentally change the subject. And when she glimpses male underwear model Matt's penis in a male restroom (it's a long story), she finds herself looking for longer than is polite.
- She also develops a taste for Yaoi. Although she attempts to hide this, she's hopeless at concealment and repeatedly caught out. Title character Dillon spots her interest and forces her to admit the truth, but she swears him to secrecy; fellow fujoshi Zii, on a guest appearance from Menage A 3, also sees through her.
- She then starts increasingly admitting the truth to herself and some others. She's openly curious about the gender-fluid Angel's sex life, and sneaks some photos of two guys practicing kissing techniques. (Fortunately, they don't mind.)
- However, she's still worried that her sort-of-boyfriend Andy will see how much she enjoys watching a gay male love scene being filmed and think badly of her. The trouble is, she's still incapable of deception.
- The Shrinking Violet Faen in Drowtales is hinted to have these tendencies, and she was the one who initiated the Relationship Upgrade between her and Ariel after years of UST. Once they're an established couple she wonders aloud if Ariel's shapeshifting abilities could be used for "something fun" and a non-canon version of Faen in a sidestory drops the covert completely and proves to be quite kinky.
- "Summoning Sweeties", a Whateley Universe story, reveals that the character of Molly is one of these. Pity her girlfriend.
- Blake Belladonna from RWBY is very much into romance novels. And by the look on her face, she doesn't want anyone to know this. However the title, "Ninjas of Love," seems to imply a much... deeper meaning than one might find for Romance novels.
- HP Lovecraft, apparently, going by his "appearance" on Ask Lovecraft. When he tries playing D&D for the first time, he asks the DM if the library is "full of comely women."
- Adventure Time
- Finn is usually cheerfully oblivious to romance beyond the very basics of crushes and kissing. However, as he is growing older and going through puberty, he has been shown to develop fanatasies and thoughts that he doesn't understand or know how to deal with (and being the last known human, pretty much forced to deal with it without much help.) This is most apparent in "All the Little People", where Finn is given a bunch of little Simish people resembling his friends and the first thing he does is start putting them in all sorts of relationships, including the Little version of himself with the Little version of Lady Rainicorn (his brother's girlfriend), then Little Finn with both Little Bubblegum and Little Flame Princess (and he blushes when they start fighting over him).
- Jake keeps that aspect of his life very private and seems like a childish goofball most of the time, but his speech to Finn in "Burning Low" heavily implies he and Lady Rainicorn have lots of kinky interspecies sex, as does a lot of her Korean dialogue. The fact that they eventually have kids confirms it, barring some sort of Bizarre Alien Biology.
- Tree Trunks, of all people. She crushed on Finn (fortunately, it never went anywhere) and in "Apple Thief" she slapped one of the Banana Guard's butts.
- In one episode of Metalocalypse, Murderface tries to sound chivalrous and defend women's honor, but his bandmates see it for what it is; a transparent ruse to get women to sleep with him. It doesn't work for him at all.
- The Broflovskis in South Park. Despite Sheila being a poster child Moral Guardian Knight Templar Parent, there have been multiple episodes alluding to their sex life including some very 'interesting' role play.
