Bludgeoning Angel Dokuro-chan: Dokuro-chan has a one foot long cone-shaped magic cell phone, which she keeps in her panties. The way she retrieves it makes it very obvious that it looks the way it does completely by intention.
In Persona -trinity soul-, every time "drawing out shadows" (you'd have to see the show to understand) is mentioned or shown it is used as an Anvilicious metaphor for sex. Oh, and it can feel good, but it can also be dangerous, so teenagers shouldn't do it with just everyone.
Guilty Crown has a fairly prominent one in episode 6, when Gai is speaking his 'sins' aloud, thinking that he's talking to Inori. He doesn't realize its Shu on the other side of a door, and the whole scene basically looks like a Catholic confessional-right down to the cross on Gai's neck.
The show is set on an island where an evil underground organization, The Glittering Crux, wants to "break the seal" of "pure maidens" to unlock "a great power"... the ability to pilot their Humongous Mecha in this world instead of their Pocket Dimension! Of course, they have to be completely nude in order for the ritual to take place...
The Glittering Crux as a whole either dress like Dominatrixes or the gay stereotype, depending on the gender.
At the end of episode 8, an entire scene consists of Takuto and Sugata panting and breathing heavily... after a big fight.
During episode 9, Sugata tells Takuto that his Kendo stick is longer while holding it at a... suggestive angle. The kicker? He says it completely seriously and nobody even lampshaded or discusses it. Did we mention that this is a Shounen series where everyone is ostensibly straight?!
The fact that Takuto is inadequate at swordplay unless he's dual-wielding... AKA has more overall "sword". Get the picture?
The constant references to "Kissing through the glass" could mean kissing or... something else.
Let's just say that the show overall is one giant Innocent Innuendo with a lot of references to other shows.
In an episode of the 2003 anime version of Fullmetal Alchemist, Riza Hawkeye is lying in her bed and moaning. It happens that she was sleeping and her dog was licking her feet to wake her up and have food.
She was also moaning "Stop that" and "That tickles." Some fans have commented (although perhaps jokingly) that she was having a sex dream about Mustang.
In Vandread, we have the three female pilots chasing after the one male pilot to "combine" throughout the entire first season.
Played with very little subtlety in Princess Nine. They team is on a trademark training trip and their alcoholic coach has decided to honor the occasion by going on the wagon. Of course, he's also doing it to try to get into the good graces of his star pitcher's (widowed) mother. Team delinquent Seira Morimura is having none of this. She strides over to his table the first night, pours him a beer and tempts/forces him to drink it (where'd a 15-year old get beer? She's a delinquent, don't ask). The dialog between coach and player makes it sound like she's tempting him with, well... other things. "It's going to be soo good." The subtext is real enough, Seira and the coach have a complicated history. She's looking for a father figure (possibly the George Michael kind) to make up for her (divorced) dad. She thought she was being hit on when he recruited her. Once the coach takes a drink, several of her teammates ask Seira what THAT was all about, and remark about the dangers of tempting older men.
In the climax arc of the first season of Shakugan no Shana, the villain Hecate (cute girl with a Nice Hat) floats above (and parallel to) main character Yuji, "synchronizing" with him and absorbing his memories, as a white "energy", which apparently feels really good, judging from the noises she makes and the way she throws her head back. The dialogue can also be easily construed to a sexual encounter.
The DVD omakes turn this into a running gag on Yuji's part - when parodying that scene, Yuji's previously chest-level flame has been moved to his crotch and Yuji moans in pleasure and begs for more while Hecate-tan glares at him and calls him a pervert.
Do you remember when the cigar-shaped Entry Plug is inserted diagonally into the Eva? Then immediately fills with an amniotic-like liquid?
Also, absolutely anything to do with one Rei Ayanami. Her relationship with Gendo, her relationship with Shinji, her numerous nude scenes, her "encounter" with the sixteenth angel...
The manga has Ka(w)oru giving Shinji mouth to mouth. Also, the two boys are in the same shower stall, inches away from each other, facing each other. It even has the kanji for "tension" between them. Yeah.
In the mouth-to-mouth scene, both of the boys were on Shinji's bed. Shinji was lying on it since he felt feverish, and Kaworu took it upon himself to climb onto the bed and position himself over Shinji's body before administering the little "re-oxygenation."Subtle, Mr. Sadamoto. Very... subtle.
Don't forget Kaworu put his leg in between Shinji's legs during that scene and started to talk about the meaning of love after they're done. Callling it Ho Yay would be an understatement.
Also by Gainax, Tengen Toppa Gurren Lagann has "power drills" as proof of manliness and the sentence "yours is a drill that breaks through to the Heavens!"
Episode 12 has a particularly blatant-and hilarious-example; Gurren Lagann drills into a port on the bottom of the ship. Cut to the bridge, where the very, very Camp Gay Leeron rises a little bit in his seat and goes "Whoo!" Cut right back to the outside of the ship.
In the same episode, Adiane destroys the Dai Gurren's lower observation deck. Cue all the male characters (curiously minus Leeron) grasping their crotch in pain when this info is relayed to them.
In Episode 15, after Lordgenome's defeat, he states the reason he lost was because Simon's Spiral Energy was bigger than his. It doesn't get any less subtle than that.
The scene in the last episode where the TTGL absorbs the power of a Big Bang in order to defeat the Anti-Spiral makes it look like the pilots are having an orgasm.
And let us not forget that all through the series, the titular mecha uses its drill to become one with other robots.
The second episode has a fairly blatant example of this as well — when Yoko leans over to admire the Core Drill Simon is holding, he looks up at her, blushes... and his drill suddenly starts glowing. Combine this with the fact that Spiral Energy is explicitly stated to be the power of evolution...
"Our manly combining must be stylish!!"
Episode 7, when we first see the big Ganman, the angle of the camera, the comments from the characters, and the overall shape simply scream "Does THIS Remind You Of Anything?!?"
Basically, Gainax forgot to fire the Freudian Psychoanalyst from the team after Eva was made.
"I want to get into that body of yours" Oh, how subtle.
In one scene, the Anti-Spiral starts deconstructing Nia. What she says, how he uses his stretched-out arm and her screaming makes this scene seem a little bit rapey:
Nia:No matter how deeply you probe my body, I won't give in!
And then in Lagann-Hen, Anti-Spiral pretty much creates a bunch of tentacles and straddles Nia... Fer God's sake, Gainax.
Dai Gurren looks extremely suggestive already, it's sort of a centaur-thing, with the bow of the battleship part being where the... ahem... would be on a human body. Now, in Episode 14, the thing rams Cytomander's ship with the bow of the battleship, penetrating it. And the explosion looks... kind of...
Also happens in the first episode when Lagann is being crushed by a Gunman. It doesn't help that Yoko's voice is a little more high-pitched than usual.
Yoko: It's no good. It's too tight!
Kamina: Don't use that strange voice in here!
Episode 197 of Keroro Gunsou just decided to stop being subtle and created a virus that is spread by drilling unsuspecting victims in the butt.You have been warned. As if it wasn't bad enough already, Giroro gets two drills when he gets infected instead of one, and that they get bigger when he thinks of Natsumi...
Speaking of Giroro, apparently his favorite method of dealing with the UST between him and Natsumi is... polishing his guns.
Chachamaru from Mahou Sensei Negima! has to be wound up, on occasion (she's a Robot Girl, after all), something which she states "feels good". When Negi winds her up, he puts waaaay too much magic into it, and she can hardly stop herself from screaming with pleasure. Chapter 263 takes it even further.
The entire Pactio system seems to exist for two reasons: 1. An excuse to give "normal" girls magical powers. 2. This trope. Additionally, when Pactio cards get brought up it will often be "Negi has already done it with seven girls!?" (Read: Anya finding out) or "Two girls in 45 minutes!? Aren't you popular." Chachamaru also danced the line between this and a Three Is Company when speaking about her martial arts training sessions with Negi ("I've been serving as Negi's partner every night and he appears to be very happy about it.") to Chisame. Chapter 253 takes the subtext to its logical conclusion. If you read it without knowing what a "pactio" is, it pretty much sounds like all of the girls are contemplating a romantic relationship with Negi or Kotaro.
The Winding is explicitly compared to the energy transfer from the Magister to his Ministra and it apparently has the same effect on all the girls.
One of the two OVAs has a scene where Negi and Nodoka are in a sauna room, and their panting from the heat is rather played up, although it's rather obvious nothing's happening.
An in-story example occurs when Negi and Setsuna arrive right after Asuna has been defeated by Fate, assuming that the worst has occurred. And it did...kind of. The event itself does bear quite a resemblance to a tentacle rape, though.
TriGun has sentient plants (the power generating kind) that are experimented on, exploited, and killed in mind-boggingly dreadful ways and that can irradiate everyone if they go berserk as metaphors both for nuclear power and vivisection. And let's not forget that in the anime, Knives is portrayed more explicitly as a kind of psycho ecoterrorist who wants to prevent humans from destroying the environment of Gunsmoke as they did to the Earth. This is quite similar to the use of Mako energy in Final Fantasy VII.
In El-Hazard, Efurita/Ifurita is awakened when a man turns her "power key" into her...
One episode of Gunslinger Girl features a character named Elsa, who describes her obsession for her handler Lauro, as the camera focuses on her polishing an assault rifle in a rather... suggestive... manner.
Even more suggestive is when Henrietta sneaks into her handler's room and finds his shirt, which she hugs to her body while lying on his bed.
Gunslinger Girl makes it very explicit that everyone who knows about the Social Welfare Agency considers the fratello relationships to be pedophilic. Some of the agents that work there even make crude jokes about it.
In Gundam 00, Setsuna is fighting Ali Al-Saachez, the mercenary who used him as a child soldier. He pins Setsuna's Gundam Exia against a rock wall with his own mobile suit, and then begins to attempt to rip out Exia's cockpit in order to crush the pilot. The cockpit is situated exactly where its name suggests it would be. "Don't touch me!" indeed.
Boy meets girl. Boy and girl are mutually attracted and spend a lot of time together. Girl has a very dangerous secret that the boy accidentally stumbles on. The boy has trouble dealing with the secret, and his fumbling reactions to it cause the girl great amounts of pain. Finally it's too much and they part ways. To the boy, it feels like the end of the world... But then the girl comes back to him. Their relationship will never be what it once was, but they have each other and a chance at something new. This is a description of a high school relationship. This is also the plot of Sai Kano.
During the finale of Full Metal Panic!, Gauron grabs Sōsuke's Humongous Mecha with his own and pins it to the floor. Sōsuke's mecha struggles to get away while Gauron says things like "let's be friends" and "I'm so happy, you've stuck with me till the end." Sōsuke is shown sweating and panting, and Gauron's broken down mecha starts leaking white liquid onto him. Of course, Gauron's ultimate intention is to detonate his mecha with 300 kilograms of explosives and kill both of them (which might very well be his idea of getting to fourth base with Sōsuke), but it looks for all the world like giant robot sexual assault.
The fact that Gauron keeps calling Sōsuke "honey" does not improve things. Neither does the fact that his last words happen to be "I love you, Kashim!" (Kashim being one of Sōsuke's aliases).
And it probably doesn't help that in the novels, Gauron literally started moaning and crying out things like "RIGHT, RIGHT, RIGHT! FASTER! MORE! MORE!!" It would probably be safe to assume that, at least in the novels, he actually didget aroused and probably orgasmed from it.
The following novels take this even further. In Sōsuke's last encounter with Gauron, the latter admits to having fantasized about screwing Sōsuke's dead body. And he says he always thought Sōsuke has beautiful eyes... "like a saint of war". Kinda romantic, really...
Shugo Chara! main character Amu possesses the "Humpty Lock" while her bad boy love interest Ikuto has the "Dumpty Key." A boy has an item that's purpose is to be inserted into an item possessed by a girl he cares for. Hmmm, now why does that seem familiar? Goes even further when Utau, who is in love with Ikuto, demands that Amu give her the lock that matches Ikuto's key. Yeah, not even gonna touch that one.
In episode 5 of Black Cat, Train gets into a... rather compromising position on top of Creed, and Creed gets really excited and breathless. More alarming are Creed's following words (especially in the Japanese version), said very much in ecstasy, "Oh, Train, you are the best!" Hmmm, sure he's only referring to Train's nimble body and fighting skills...
Pretty much anything regarding Creed and his obsessive stalkerish love for Train. Also, Creed even begs (in a very perverted way) for Train to shoot him in the head, that he will take any bullet he has because, in Creed's words "once I have taken it you and I will be bonded forever."
And then there's Germany and Italy'swhole relationship. They've seen each other naked often, share a bed, and in one strip, Italy bursts into Germany's shower to ask him if he "likes" him and demands that Germany tell him he loves him. When Germany does, he shouts, "Yahoo! I love you too!" Then their friend Japan catches them both naked in the shower. Italy's reaction? He says "I did it, Japan! I got closer to Germany!" while naked and laying underneath an equally naked Germany.
In Hetalia Bloodbath 2011 the Spain/Romano strip; Romano has some work he has to do, and Spain offers to give him his "cheerfulness for a charm", while Romano says he "doesn't want it"... then Spain crawls under the desk, there's a pause... then Spain does something and Romano snaps "I told you not to!". Fans were not shy at all about the dirty implications of all this, especially before the strip was translated.
Kariya force-feeding some purified spirit energy to a reluctant Mabashi — by shoving an engorged, bulbous object into his mouth and forcing him to swallow the fluid that comes out, complete with muffled choking, sputtering noises. Make what you will of Mabashi's subsequent attitude change.
Pesche keeps his sword in his loincloth. When he goes to pull it out, he severely Squicks Uryuu and Renji.
In the anime, when Neliel bear-hugged Ichigo after turning into an adult, the camera is positioned in such a way that it looks like she's humping him◊. Orihime's expression says it best.
During the Soul Society Arc, Ichigo is repeatedly referred to as "having a zanpakutou big as he is tall" and made fun of for having no control over his big, flashy powers. This is reinforced when Ichigo's dad dispatches of Grand Fisher by telling him that Captain-league shinigami have to consciously control their reiatsu, or they'd be running around with swords the size of skyscrapers. It's because of such statements that zanpakutou earned the Fan Nickname "Soul Penis".
Ichimaru Gin's Shinso... "Bankai, Kamishini no Yari"... It extends up to 13 kilometers. Without a doubt Gin has the longest in all of Soul Society. Then after that he has a technique that repeatedly extends and contracts his blade.
Ichigo and friends are told that one of them is an impostor. Ichigo tries to get Renji to get out of his gigai to prove that he is the real Renji, and they end up rolling around on the ground with Ichigo screaming "Take it off!" Their classmates are rather shocked. (Save for the drooling Chizuru)
Ishida and Ichigo discuss how to fight a (somewhat phallic) Menos Grande. Some of this involves "cutting it off at the knees". And then it involves "wow my bow sure gets big when I touch your soul-sword!"
Ulquiorra has a speech where he tells Orihime he will "tie you up and force it down your throat" He was talking about food, but still...
Hisagi has "69" tattoo on his face, based on one former Ninth Division captain Kensei Muguruma has on his chest.
Yumichika has a secret about his sword (which could be described as "not having a manly enough shikai") he conceals from everyone around him for fear that, if it got out, he would be disowned by Ikkaku or expelled from the squad. This secret is so important to him that he's willing to risk death in battle rather than use his shikai where someone from the 11th might see. Replace "sword" with "sexual orientation" and it's easy to see how part of the fanbase interprets his devotion to Ikkaku as an unreciprocated crush. Given that Japanese and American straight/gay stereotypes are often reversed, another part of the fanbase regards this as an example of Unfortunate Implications or Values Dissonance instead.
When Riruka first gets a good look at Ichigo's face, his hotness causes her to freeze for several moments before crying out and collapsing to her knees, breathless and flushed.
Riruka's ability is laden with innuendos about what she "loves".
"Just now I gave you 'permission', and 'invited' you into this beloved box of mine."
Hell, Nnoitra's very design is loaded with Freudian imagery. His one eye, his gigantic spoon-shaped hood, his huge ax/sickle weapon, his unusual Noodle People-like design, his Overly-Long Tongue, which is compounded by the fact that he fires a golden Cero from the tip of it. His molester personality and extreme inferiority complex is the icing on the cake that seems to say that Nnoitra is Compensating for Something with everything.
Hitsugaya walks in on a drunk Matsumoto while she's napping. She's giggling in her sleep and whispering "Stop...no don't stop..."
At the very end of the second InuYasha movie, in the scene where they discuss the fact that Kagome kissed Inuyasha, the way they talk around the fact gives the impression that they're talking about sex.
Not to mention most of the series is dedicated to make Inuyasha's sword better and more capable... The sword that grows in size when he thinks about the women in his life, has a hairy ruff at the base, something like independent preferences, and yeah, a pulse. Later, it even becomes dark-tinted...
In the seventh episode of Yami No Matsuei, Muraki has a very... odd way of holding his wine glass. Let's just say he keeps moving his hand up and down while holding it (all the while leering at Tsuzuki and talking about how beautiful Tsuzuki's eyes are).
This page from Chapter 34 of the manga. (It's vomit.)
In episode 6 of the second season of the anime when Hannah, a well-endowed sexy woman, gets ready to play the armonica she licks her fingers and then sticks two of her fingers in her mouth leading Sebastian's staff to blush at the sight.
From that same episode: the line which Sebastian says to Claude, "That white, sticky spider's thread of yours tarnished bocchan's... soul."
Sora Wo Kakeru Shoujo has this with Leopard's antimatter cannon. It requires two "Golden Orbs" to fire, does not function when said orbs are cold, results in a flurry of some white (ashlike) substance covering everything inside Leopard (including the female protagonist) when fired, and has a "relaxing", so to speak, effect on Leopard, while the effect on the female protagonist is a bit more exhaustive.
Death Note's foot massage scene. Other than the biblical symbolism and context of it, there can be other implications. Of course, the entire thing isn't helped by how the anime made it seem like L had a foot fetish. Both Light and L are soaking wet, drying themselves off, and their dialogue and actions go something like this:
Light: What are you doing, Ryuuzaki?! L: At least allow me to atone for this. I'm not all that bad at it, you know. Light:(looking away) Do as you please. (L presses Light's foot, and Light cries out) L: Oi, you'll get used to it quickly. Light: You're still wet. L: Sorry...
There's also one of Mikami's Sakujo-gasms in the anime which includes slow motion, a fall backwards, and a very, very joyful look on his face that resembles an orgasm more than a killing. The same Sakujo-gasm also has what appear to be large drops of shiny white sweat, with a spotlight on his crotch seen at the end of this video, which includes every instance of his Catch Phrase.
Light's usage of the Death Note in general can be seen as a sexual release. And then there's the fact that he completely ignores the incredibly hot woman throwing herself at him...
There's an instance in one of the first few episodes where, after a long, energetic sequence where he wrote in the Death Note (all the while seeming quite happy with it), Light flops back in his desk chair and pants.
Ryuk: You've taken quite a liking to it.
A tragic, non-Freudian example: In episode 7 of Haibane Renmei, Rakka's reaction to Ku taking her Day of Flight feels very much like somebody's reaction to suicide.
In the opening video of the Ultimate Ninja Storm 2 video game (remade from the anime but with the video game graphics) Sakura is shown after the Leaf Village got nuked calling out for Naruto to hurry up and arrive. In the anime version, she's right about at the center of the screen. In the video game version, it looks like she's having sex with someone just below the screen. Especially with the sound off. Press 6 once on the page to see.
Also, in chapter 491 when Naruto is forced to swallow a seal frog
"Hey! Can't you open wider!? Do you want me in you or not!?"
Naruto and Sasuke's entire battle at Valley Of The End had some instances which can be interpreted as this. Dubbed!Sasuke makes it even more apparent. Shortly after meeting up with Sasuke at Valley Of The End Naruto tackles Sasuke to the ground, straddles him and punches him across the face. Sasuke then spits blood at Naruto's face and they grab each other by the shirt pulling their faces close to the others. Then Sasuke laughs and, in the dubbed version says "Remember how thrilled you were at the thought of beating me to a bloody pulp? What's wrong? Where's your smile now?" And, in the anime only, there's a scene where Sasuke finds Naruto, grins, rushes at him, grabs his wrists, and gets really close before kicking him away.
When Naruto and Sasuke had their first reunion after the Timeskip Sasuke half-hugging Naruto as he whispers in his ear and attempts to plunge his sword through Naruto's back looked more like he was preparing to have sex with him than that he was trying to kill him.
Speaking of Akatsuki, they were formed by teens in a country that was a battleground for several superpowers, including the protagonist's village. They began with good intentions, then things got messed up. Akatsuki is a metaphor for the Taliban. Especially if you consider the nature of Deidara and Pain's attacks...
In a filler arc, Kabuto and Yukimaru, a young boy, are isolated in the middle of a lake. They have a conversation that goes something like this.
Yukimaru: I have a feeling something fun is about to start. Kabuto: Yes, we're going to have some fun. Can you put this on? He then proceeds to give him a strange pill. Cut to a few seconds later, Yukimaru is screaming.
Given that Kabuto is the right hand man to a guy who is known for taking little children away from their parents, this seems rather bad.
From the same arc, one from hallucination-Orochimaru: "Sasuke will have the power he desires... and I will have him." *groan*
There's also in recent chapters, where Kabuto summoning dead people involves them sprouting waist-up from his chest◊, making it look quite a bit like he's humping them.
Several fans have noticed Ho Yay / Foe Yay between Kisame and Killer Bee. You see, both of them getting really close to each other's faces, Kisame's sword Samehada REALLY, REALLY likes Killer Bee, and Killer Bee did say that Kisame had "pretty eyes". Kisame goes shirtless during their fight and they both end up soaked with water and splattered with Killerbee's ink. Then Kisame attempts to cut off Killerbee's feet so he won't be able to get away but the way it looks... with a shirtless Kisame standing overtop Killerbee who's on the ground struggling to get away...
Suigetsu once threatened Sasuke from behind while naked.
There's a really long snake coming out of Kabuto's stomach. Suigetsu is... quick to notice.
Suigetsu: Kinda gross. This thing coming out of his belly looks just like a huge- Sasuke: You can leave it there.
In Claymore, during the first battle in Pieta, one of awakened beings looks like a giant turtle with a slightly phallic head. Jean doesn't help any when she states "One blow isn't enough, he's too hard".
Lucky Star has a scene with Konata lying on her back and choking on Cherry Blossoms. It's all the more suggestive for the few seconds her face is off-screen.
Speaking of Da Capo, Miharu's first "wind-up" in episode 3 of the first season is similar to the trope pic. Needs a key to wind-up. Key goes in a hole (on her back). Tickles when her hole is touched. You get the idea.
Just about everything with Hyatt in Excel♥Saga. Excel has a memorable scene where's she's rolling on the floor with a mannequin dressed up as Il Palazzo while kicking her feet in the air and screaming his name.
Hyatt? Hell, she's at it from the opening credits onwards. That shot of her eating a banana is about as unsubtle as can possibly be done.
To not mention the scene where Excel is watching the guy 'play his guitar' through a curtain, That's really as unsubtle as it gets.
Corrector Yui's transformation sequences have the girls (Yui, Haruna and Ai) making pretty... orgasmic faces when they get the chest jewel of their virtual costumes put on them. Here's the proof.
Hunter × Hunter: Everything involving Hisoka and his "interest" in Killua and Gon, what with all his talk of "waiting until the fruit is ripe" and basically getting 'aroused' when both of them happen to see him naked and making moaning noises as he stares at their butts.
In the Magical Girl show Prétear, the main character transforms by merging her life energy with one of the seven bishounen Léafe Knights. The Transformation Sequence shows both Himeno and the Knight naked, embracing, with the girl making a rather orgasmic face, before the knight turns into a ball (or "seed" if you will) of energy that implants itself into her body. You can see one of them here. This is lampshaded to hell in back in the series—from the Knights describing it as "becoming one" (with the flirty one of the bunch describing it in flowery, innuendo-filled detail) and Himeno exclaiming before one of her earlier transformations that she's "not sure if I'm ready for that sort of emotional commitment yet!"
This possibly has further symbolic consequences. Since Prétear's Applied Phlebotinum is effectively Life, the entire "becoming one" thing is understandable (since this is how people create new life in reality). However, one could note that the anime's Grand Finale Himeno manages to achieve the form of the Legendary White Prétear without merging with a Knight. Think about it for a second. Doesn't help that she further gets into the territory of Messianic Archetype by sacrificing herself. Well, temporarily, anyway.
A Rurouni Kenshin filler episode where Yahiko had to impersonate a foreign prince. The way they force him to wear the prince's clothes looks like they're about to rape him.
Hayate the Combat Butler almost pulls this off without a sexual context that's usually displayed. When Hinagiku gains donkey ears (no, even in context it doesn't make sense), she comments that she can't let Hayate see her. Guess who shows up. Every other time a character (usually her sister) bursts in on her without knocking, she's in the middle of dressing/undressing.
Most likely not intentional, but the dubbed version of the second to last episode of Moribito when Balsa and Tanda are getting the egg out of Chagum. "Put your hand in him" "IT HURTS!" The grunting in pain Chagum makes certainly doesn't help. Chagum is twelve by the way...
Actually, it looks a lot like a birth scene... which it sort of is.
In Jungle De Ikou, there are the girls' transformations... they make very sexual motions (our heroine moves like she's being slammed against a wall, her friend moves up and down), and immediately to transforming, they have a very orgasmic face, complete with a loud "Ohhhh!"
Air Gear: Arthur is a masochist who pelvic thrusts against his male opponent Agito and nibbles on his ear while fighting him. He also has flamboyant mannerisms, speaks in a polite manner, and frequently releases heart marks whenever he's reveling in the feeling of pain. Shalott is a loli who wears a frilly looking dress and drops a Bridget on Agito, revealing that he's actually a girly-looking guy who is in a BDSM type relationship with Arthur. The end of chapter 279 has him pin Agito to the ground and straddle him, saying after he tortures him then Agito can "lick it" if he wants.
Get Backers: Anything Takuma Fudou says to Ban. After Ban ripped off Fudou's arm, Fudou becomes completelyobsessed with Ban. He even keeps his own severed, rotting arm with him to constantly remind himself of Ban - which made him feel "incredible chills rising up throughout his body." And when he isn't talking to Ban, every word coming from his mouth is normally about Ban. Some notably lines include: "COME, COME, COME, COME, your eyes, your flesh, blood, your screams, GIVE YOUR BODY TO ME! MEET MY DESIRES!" "Don't die yet, Mido - I'm not finished. You still need to quench my thirst - I'm not done. Let me enjoy myself." "What was my job again? My mind goes blank whenever I see you." "The only thing that can stop this shaking... is for me to slurp up your blood!"
Katekyo Hitman Reborn!: Glo Xinia's Foe Yay with Chrome. Considering how during his fight with Chrome he grabbed her hard enough to cause her pain, kept getting in her face, and told her things like: "You seem to like being touched by men. Your blushing cannot betray your desires." "Give me MORE!" (after hearing her screams of pain) and "It's time to eat... that ring and you!" It's hinted he might've done something to her had Mukuro not shown up, allowing her time to escape. Also, when fighting Mukuro he comes out with this line: "Is that girl so precious to you? Then I'm going to take my share of such a precious girl right before your eyes. This could just be the best situation, don't you think? My appetite for that girl just keeps getting better!" and "Don't worry Chrome, I will take good care of you for MUKURO TO SEE!"
Also, in Lussuria's words his favorite bodies are the "wasted, cold, unmoving" ones. Unfortunately, Ryohei goes topless during his fight against Lussuria and this only serves to make Lussuria his hardcore fanboy. In fact, Lussuria actually openly ogles Ryohei's muscular physique and refers to his body as "pretty nice", says that he's "just his type" and promptly decides to take him home and make him a part of his "collection" after he beats him up.
All throughout Byakuran's battle with Tsuna we see Byakuran ruthlessly attack Tsuna and taunt him with things like "Very scary, ain't it?" while clearly enjoying the nervous/shocked expressions on Tsuna's face. Also, from the ending of Chapter 275 all throughout Chapter 276 we see Byakuran stealing a page out of Mukuro's book by grabbing Tsuna from behind and suffocating him - meaning Tsuna's all flushed, gasping, weakly fighting back, etc. while Byakuran never stops smiling, calling him Tsunayoshi-kun, and breathing things like "look at how helpless you are..." into his ear.
And the part during Mukuro's fight with Tsuna where he suddenly grabbed Tsuna from behind, whispered into his ear and looked like he was resting his chin on Tsuna's shoulder was oddly reminiscent of a I Have You Now, My Pretty ploy. His Grand Theft Me tactic where he wants to possess Tsuna's body so he can cause a rift within the mafia which has him repeatedly telling Tsuna to "give me your body", "I'm going to have some goddamn fun with you, and "With my ultimate technique you will be mine." Not to mention if you replay that part it in the anime it looks like he's raping Tsuna/having sex with Tsuna.
In episode 46 when Gokudera and Belphegor are trying to take each other's rings, at one point, Belphegor straddles Gokudera and all the struggling they're doing makes it look like they're having sex or that Belphegor is raping Gokudera.
Yamamoto got a Shirtless Scene in episode 100 of the anime, which verged on Shower Scene. With more Fanservice of the gratuitous Ho Yay sort, as Gokudera (again) comes in the changing room and starts taking off his shoes while sitting in front of a standing, still shirtless Yamamoto. The angle also makes it look like his head is level with Yamamoto's crotch.
And Julie Katou/Daemon Sapde expresses interest in Chrome and kidnaps her, telling her they have "date plans" and lets her sleep in his bed. He also finds her to be "so damn cute" and in chapter 309 Chrome awakens in his bed, he enters the room, offers her a change of clothes, gets onto the bed with her, grabs her face, gets real close and asks if she needs help changing. He then says they should "get to know each other, real nice".
D.Gray-Man has this with Tyki "killing" Allen (which resembled a sort of "violation," with Tyki sticking his hand into Allen), the suggestive dialogue with Tyki telling Allen, "Don't be so cold, boy. An Exorcist made a Noah strip down to his underwear. Was that the first time you did it? Do you think it was destiny for it to be us?" and Tyki seeming miffed when Allen tells him that he'd done it to many people before. During their fight later, there's another Does This Remind You Of Anything moment with Tyki telling Allen, "This is giving me the thrills. I'll break you, one more time, with this hand!" Road tells Lavi that Tyki likes Allen as much as she does (this being after it was established that she likes Allen enough to kiss him).
In one of the first episodes after Allen is defeated by Tyki in the anime, he says that he "lost his Innocence to Tyki". At least, that's how one fansub-group decided to translate it.
In one episode of the anime, Mimi holds up Lavi's hammer in its small form and says "Looks like someone lost his Innocence!" He gets it back.
Any reference to collecting, losing or destroying Innocence could be interpreted as this.
WORKING! episode 13 features Takanashi going through a complicated analogy the end-result of which is to confirm Inami's cuteness. Inami (who is holding a pair of soda cans at the time) goes red-faced, crushes the cans with her fists and has her face covered with white liquid...
Vampire Knight: Although it's not obvious, the Kiss of the Vampire serves as a metaphor for sex. Especially with regard to the "secret relationship" between Yuuki and Zero during volumes 3 and beyond. In other words, Zero is "boning" both Yuuki and Kaname. Seen in this light, the final scene with Zero and Ichiru is quite symbolic as well.
Also, Takuma Ichijo and Senri Shiki. There is one scene in the manga, at Ichijo's birthday party, where Shiki "accidently" cuts Ichijo with the knife while attempting to cut the cake. Cue Shiki, who prefers real blood over blood tablets, commenting on how they shouldn't waste it, licking Takuma's blood off his hand. With an almost lustful expression on his face.
Ultimate Girls. The anime is made out of this trope. From the "transformation rod" to monsters' weak spots, you can't watch it without your mind looking around and saying, "Gutter, gutter, and more gutter."
Karin: The biting. "It'll only hurt for a moment" indeed...
In the first episode of Karin, Karin's vampiric attraction to her (female) best friend Maki is reminiscent of a lesbian attraction. She even leans in to bite Maki's neck, which looks very much like an attempted kiss.
There was also the picture of Karin when she gushed blood for the first time. The caption read: "Karin's a big girl, now"
Or one of the chapters where Karin's brother is forcing Bridget to be burned by sunlight by bending her over and sticking her head out the window while he is bent over her from behind, grabbing her so she can't struggle. That doesn't seem like rape at all, right? Oh, and then he and she later confirm that he spent the rest of the night forcing sex on her. But apparently, it's a case of rape leading to love for her. She also calls later to say she's pregnant.
The bleeding. When Karin and Anju's respective first times at biting a victim are shown, both of them have the fronts of their white dresses conspicuously covered in "virginal" blood. Afterwards, both are referred to as vampires and adults.
Also, that certain time of the month where Karin's blood begins to multiply is reminiscent of... a certain other time of the month.
Episode 11 of Seitokai Yakuindomo has the girls (along with Tsuda's little sister) decide to go to Tsuda's room to play board games. Naturally, they barge into his room with what can only be called "rape faces◊," declare while giggling evilly that "You won't be getting any sleep tonight," and the scene ends with Tsuda screaming.
Texhnolyze: All over the place, thanks to a heavy reliance on symbolism and metaphor to convey the story. Perhaps the most disturbing moment of this was when Onishi discovered Michiko after she had been beaten and raped by a bunch of thugs, and she grabs his sword in a disturbingly suggestive manner.
Panty & Stocking with Garterbelt is at least 50% this. Notable examples include: a scene in which Panty and a guy are sticking their fingers into each other, talking about how great it feels...and then it turns out that they're picking each other's noses; and a scene involving Scanty,Kneesocks, figs, milk, and some very suggestive silhouettes...
Really. Wasn't it enough that the main characters are called Panty and Stocking? How about the fact that Panty's gun is her panties? It's fine with Stocking, but Panty is basically fighting semi-naked.
The manga Kamisama Dolls features an... interesting scene between the evil character, Aki, and an older woman, Kuuko. The latter involves herself in the Secret War because she wants to study the titular dolls (which are actually the "shells of gods" controlled by select humans called Seki). She does this by kidnapping, stripping and imprisoning Aki at her home then interrogating him by firing an air-soft gun at him until he agrees to show her his doll (called a Kakashi). He quickly gets pissed off at her violent, insane tactics and does indeed call upon his servant, having it phase through the floor, knocking Kuuko on her back and slicing her clothes right down the middle. As he's redressing, Aki makes the following exchange (made all the more suggestive by Kuuko panting and blushing the whole time):
Aki: How was it? I showed it to you, just like you wanted. (smiles) What do you think?
And the Yu-Gi-Oh! manga actually has a really uncomfortable variation with Dark Malik; all his duels are set up to seem reminiscent of rape. It doesn't help that he's literally getting off on the pain he's experiencing during the duel...
Tiger & Bunny. Maverick drugging Barnaby and then showing himself as a madman in front of a semi-paralyzed and emotionally broken Bunny in episode 19. And in episode 20, Barnaby wakes up all disoriented in Maverick's home, while the other is making him breakfast. Date rape comparisons, anyone?
In Sailor Moon, the Amazon Trio looking into people's dream mirrors is pretty reminiscent of rape. How so? They look into the mirrors via forcibly sticking their head into them. While the victim screams in pain or discomfort. After seducing the poor Jane/John Doe to draw him/her to a secluded spot — and having them bound and helpless.
Not helped by the fact that each one of them (Fish Eye, Hawk Eye, and Tiger Eye) have a particular type they like to target. Or the fact that they sometimes yell "YES!" and other exclamations of enjoyment while perusing the victim's mirror. Or...let's just say that the animators really ran with this metaphor.
In Koharu No Hibi the scene where Koharu enthusiastically licks the recorder of the guy she's in love with while breathing heavily and blushing.
Rust Blaster: Referring to a vampire bite "It hurt the first time you did it. Can you be more gentle this time?"
Hisoka of Hunter × Hunter has a particular fascination with Gon and Killua, stares at their butts while moaning in one scene and calls them "unripe" fruit that he wants to pick, meaning he wants to kill them at the end of a fight where they would be strong, but still...
Vassalord features a lot of this. Particularly memorable was the scene where Charley fed from Rayflo by kneeling in front of him and sucking on his... inner thigh. All with Rayflo blushing and breathing heavily.
D.N.Angel: The "pendants of eternal friendship" that Mio gave Riku to use with Daisuke. Also, there's a scene in Stage Four (manga volume 15) in which Satoshi's adopted father forces Satoshi to transform while holding him down over a table - yes, the entire has very disturbing rape undertones.
Ultimo: "Please put your hand inside me Yamato-sama."
Code Geass: The second season reveals that during the Time Skip, the Emperor used his own Geass to give Lelouch Fake Memories. The scene gets almost uncomfortably close to an actual rape, with Suzaku holding Lelouch down and Lelouch begging for him to stop.
In Code Geass R2. Suzaku, trying to find out if Lelouch has regained his memory and become Zero again, attempts to use the Refrain drug on Kallen to make her tell him the truth. Kallen is so disturbed and shaken that she begs for him not to, as though she were about to be literally raped by him. Just before dosing her, Suzaku realizes he is becoming Not So Different from Zero, and stops. When you think back to season one and how the mind of Kallen's biological mother was nearly destroyed by the drug, it's not that much of a stretch to believe that poor Kallen would liken a forced dose of refrain to a sexual violation.
Zero no Tsukaima is full of this. Take for example: In episode 2 of the fourth season you get the feeling that Joseph was about to rape Louise for a second when he said she was gonna "lose her honor" then you see his robe lowering and how he kneels in front of her while she's tied up on the ground and touches her face...
Bakemonogatari: The "staple stable" opening features what appear to be staplers in rough approximations of sex positions.
During the car ride in Episode 12, Senjogahara runs her fingers along Koyomi's thigh. Cue cut to the gas meter dinging empty.
It's augmented by her whispering obscene words to him and sensually biting his ear while he's fidgeting and whimpering "St-stop it." It's all wrapped up by seeing his hair that once stood pointed and firm, turn all flaccid. At this point, it's not even subtext.
Not at all sexual and probably highly disturbing, when Koyomi has Shinobu drink his blood so he can regain some amount of a vampire's abilities, the scene is highly reminiscent of a mother nursing an infant. He even pats her back to get her to let go.
The scene where Koyomi touches Suruga's monkey arm. He even lampshades it by yelling at her for making weird noises.
The scene in "Tsukihi Phoenix" where Koyomi brushes Karen's teeth and everything leading up to it is uncomfortably evocative of rape.
A half human half spider hybrid appears in the first OVA of Angel's Feather. When he appears he wraps Shou up in his web, caresses him, gets close to his face, sticks his finger in his mouth which causes Shou to blush, and licks him before trying to murder him by penetrating his body with his pincher.
In the English dub of the anime Fruits Basket Kyo and Yuki start almost all of their fights by shouting "Let's do it!" and clenching the fronts of each others' shirts. Kyo and Haru do this once in episode 10 as well.
In episode 87 of Ranma One Half, when Ryōga falls on top of Ranma in the path of an oncoming train, Ranma tries to get Ryōga off of him and all the movement makes it look like they're having sex.
The way Caribou from One Piece behaves when he kidnaps mermaids with his mud powers. Take a look at panels of these scenes in the manga. Those scenes are made even worse in the anime, because not only is everything in motion, you can hear Caribou's creepy manner of speaking all while the mermaids cry for help.
Vividred Operation: "Docking" is an obvious metaphor for sex. It's initiated by kissing someone with whom you have a close personal bond, and generates lines like "I could feel you flowing into me." Some of the attack names are also this trope: Naked Blade, Naked Collider...
In Kirby of the Stars King Dedede once get the Cappies (with the help of a Demon Beast) to teach the children that he is the greatest guy there is, and that everything is discovered by him. Much like the North Korean education system where every subject revolves around the Kim Jong-Il being a the greatest man in the world and he invented everything.
FLCL might as well be called "Sexual Innuendo and Double Entendres: The Series", from phallic objects shooting out of Naoto's forehead, to Amaro overcompensating for his tiny, tiny eyebrows with a huge pair of fake ones, to loads and loads of lines whose context sound very, very different if you aren't looking at the screen.
In this show, Boyfriend=Official Dance Partner (and vice versa). Rue makes Mytho dance with her a lot. And then...
Rue/Kraehe kisses him as she removes the feeling of love from his heart, kidnapping him and turning him into an Empty Shell. And then we see them lying down together on a bed of feathers, with Kraehe in her Stripperific tutu and Mytho completely naked. As a result of this, his heart is tainted. Doesn't help that this all comes shortly after Mr. Cat gives Mytho a thinly-veiled Talk.
In season 2, Dark!Mytho starts taking advantage of the many, many girls who fall in love with him, luring them into dark, secluded places for them to prove their love to him. They offer themselves up to him so that he can take away their pure, innocent hearts. He is literally trying to steal their hearts (which would effectively turn them into Empty Shells), but that might just make him seem more like a sexual predator.
