When a character (usually female, but not always) eats something. Really slowly and suggestively, as a phallic or yonic metaphor. Or moves it in and out of her mouth, in the same way. Bonus points for drips on mouth and/or chest.
Common items are:
Fruit (especially bananas).
Long, thin sweets or pastries (i.e. chocolate fingers or candy bars).
Frozen desserts (especially popsicles and vanilla ice cream).
Häagen-Dazs had adverts which featured women (and men) having an orgasm while eating their ice cream.
Just about every commercial there has ever been for Cadbury's Flake, a stick-shaped chocolate bar, has shown a woman slowly peeling back the wrapper, biting off a chunk, closing her eyes and going into blissful raptures. They weren't allowed to be broadcast before the watershed.
Bill Bailey parodies this in a stage show, involving the Flake jingle and some footage of animals copulating.
All Magnum ice cream ads are this to varying degrees. They even have actors describing ice cream as if it was sex with the cream dripping off their lips...
The "girrrrrrthy" commercials that Ball Park Franks ran a while back.
An old commercial praised the ability of a girl who could unwrap a Starburst with her tongue.
A Diet Pepper Cherry commercial shows Fergie (of the Black Eyed Peas, not the British royal family) tying a cherry stem into a knot with her tongue. The kicker here is that Fergie had just drank a can of the soda, implying that it has so much cherry flavor it...well, has cherry stems, apparently.
Parodied in the Carl's Jr. commercial where a gorgeous girl in a bathing suit is shown soaping a car and herself while sensuously eating a giant hamburger. The ad was pulled after protests from Moral Guardians. Carl's Jr. later tried again with another beautiful girl, this time eating a chicken cranberry salad in bed and in her bath.
Tums has a series of ads where food literally fights the would-be eater. It takes on a whole new meaning when the food is a mustard-slathered corn dog. His date covering her stuffed toy's eyes confirm the commercial's makers knew exactly what this looked like!
Anime and Manga
Excel Saga: The opening sequence has Hyatt eating a banana very suggestively.
Lesbian example from Mnemosyne: A woman orders a drink at a bar, but instead of sipping it normally, she dips two fingers into it and then licks the liquid off them.
In a chapter of You're Under Arrest!, Ken Nakajima is watching very interestedly what is implied is an AV, but the only scene we can see before he is interrupted and had to hide the "evidence" is a close-up of a cute girl licking an vanilla ice cream cone.
The Eiken anime did this in the second episode. One of the events in the school competition was to swallow a chocolate-covered banana, and the announcer noted that the Eiken Club member in the event obviously had experience doing this sort of thing... Not to mention the club president is rarely not seen eating food like bananas and sausages in very suggestible ways.
Miharu in the Girls Bravo anime did this, not to one banana, but to a fruit vendor's entire stock in quick succession, while he was telling a story about the experiences that inspired him to sell bananas. To multiple highly suggestive camera angles!
In episode 6 of Kanokon, Nozomu eats a Candied Apple in an indecent fashion, complete with hentai-style drool. Chizuru does not take kindly to being upstaged, however, and it soon turns into an actual Erotic Eating Competition, with many types of carnival food being drafted for the festivities.
There are a pair of doujinshi of Neon Genesis Evangelion that play with this. The first one consists of Asuka laying on the floor with suspicious white stuff on her hands and face, she had just been in an ice cream eating contest... with Rei. The other is Asuka licking something rather... flesh-colored while kneeling in front of a very embarrassed and nervous Shinji. It's a Red Bean paste popsicle.
Episode 4 gives us Haruko and Naota's father eating eggs rather suggestively.
In Episode 5, while Naota is talking with his friends about how he saved the town in the previous episode, Ninamori can be seen looking unimpressed as she eats a Popsicle in a suggestive manner. Takes a quick dip towards horrific when she stops sucking it suggestively and... chomp!'
Great Teacher Onizuka features original sketches on the inside cover pages of each tankobon (collected volume consisting of several chapters released weekly on Shonen Jump), and one was of Urumi nibbling on half of a Pocky as a very surprised Tomoko (I think) is eating the other end.
Shion Sonozaki from Higurashi no Naku Koro ni seems to get a little too much enjoyment from eating a popsicle while plotting her deceit and subsequent murder of the village chief and Keiichi.

Kyou from Clannad when she was slowly sucking a lollipop.
Shin Koihime†Musou has a gratuitous scene with what happens to be a primitive form of glowstick in episode four.
Revolutionary Girl Utena: The sensual yet vicious manner with which Akio devours a flower in one of the later episodes tells you pretty much everything you need to know about his relationship to women and sex.
L does this constantly. He licks donuts, spoons, and his own fingers; he goes through strawberries and a banana; and once he ties a cherry stem with his tongue. The cast has more important things to do than notice any of this.
Misa does this too. Intentionally played, as well, since she was starring in a lipstick commercial that involved her biting the skin off a banana.
Kanna from Koe de Oshigoto! is encouraged to try this with various foods, including a banana, to improve her technique (she's an eroge seiyuu, who are expected to provide their own sound effects, among other things). This fails completely and is shown as a throwaway gag, rather than used for fan service. The finger sucking on the other hand goes way beyond Does This Remind You of Anything? territory.
Dead Leaves kicks off with Pandy sucking furiously on a hot dog... for no apparent reason.
Bleach has Orihime eating a hot dog rather... oddly during the X-Cution arc.
Rangiku's enthusiastically licking a popsicle during the Beach Episode.
07Ghost: Those candy things Castor gives Teito and Razette in episode 4.
Maji De Watashi Ni Koi Shinasai has the lollipops in episode 6, which actually represents what they look like. Momoyo evens lectures the other heroines on how to "eat" the lollipop, while lots of guys watch them as if they could actually feel it themselves. Then she tells them to take a bite off. All the guys immediately collapse in pain. A little later, Fushikawa tries to pull off the exact same thing. She succeeds just as spectacularly.
While it doesn't actually show up in Steins Gate, it gets referenced.
Makise: I'm going to eat this banana.
Hashida: Can you say that again...but sort of whisper it?
Kingdom Hearts II: Axel. Roxas. Sea salt ice cream. If something combining all of these things doesn't appear here, then Yaoi Fangirls aren't doing their job. Or are... otherwise occupied.
In the Power Rangers epic "Of Love And Bunnies", an order of fries drops down Kim (the original Pink Ranger)'s bra after Tommy (her ex-boyfriend and former White Ranger), driving the jeep they're in, hits a pothole. Tommy finds he can see down her shirt through the rear-view mirror and starts swerving off the road. Kim realizes this and starts eating the fries as suggestively as possible and making a few... choice comments.
From another Power Rangers fic, albeit an original one named Power Rangers GPX, the Yellow Ranger Maria Aparicio eats a chocolate cake so suggestively it's almost an homage to When Harry Met Sally. In her justification, however, it is stated to be some damn good cake.
One The X-Files fanfic features Mulder daydreaming to kill time during an insanely boring meeting. It works...until he sees Scully munching on a banana. His daydreams get to the point of needing cold water.
Aimo's Dragon Age fan comic "Wonderland" here, (though you need a DeviantArt registration to see it) uses peaches, hard candy, milkshakes, cotton candy, and various things with cherries as a hilarious multifaceted metaphor for cunnilingus. Some of her other fan comics feature erotic eating as well, including "Strawberries and Cream" (of course) and "Curiousity" [sic].
Weightless: After Kaidan's death, Shepard isolated and starved herself in her cabin, Garrus tried to get her to eat some chocolate. When she finally ate them, she did it while laying on her bed, completed with moaning and fingers-licking. Thanks to it, Garrus, who've been carrying the flame for her for months, kinda lost control and things went downhill from there (not in a good way).
One character in Horrible Bosses seduces another by eating a popsicle, a banana, and a hot dog. In that order.
One scene in the film Tom Jones has Tom and a buxom woman consuming their dinner rather... suggestively to each other.

It's also parodied by a 1970s Dave Allen sketch, in which they're too busy throwing up afterwards to think about sex.
Parodied also in Bananas as Woody Allen and a rebel girl eat together - he playfully tosses a piece of food to her, then gets a plateful of food in his face.

Face Off: Castor Troy's favorite thing to say, so much so that they used it as his voice test when his enemy got his face was "Peach. I can eat a peach for hours."
El Topo: This truly bizarre Mexican Western has a scene where eating fruit becomes a visual metaphor for lesbian sex.
Go Fish: In the cult lesbian movie, the love scene is intercut with a cooking scene. It works surprisingly well.

In A Clockwork Orange, the two girls Alex met in a record store were sucking on popsicles. Not just any popsicles, either; they're actually ... um ... anatomically correct popsicles.
An egg being passed from mouth to mouth between lovers in one scene, for starters...
Then there's the scene where the Gangster licks honey from his girlfriend's lips, strongly suggesting he's licking a different body part. In fact, roughly a third of the movie is this trope.
A Night At The Roxbury: Subverted. While having a nice lunch party with Steve's intended in-laws (regardless of what he thinks about the matter) his fiancee, sex-crazed Emily Sanderson (who the film has spent a great deal of time trying to make the audience loathe) tries this on Steve. He does not have the reaction she was looking for.

Rocky Horror Picture Show: While not directly part of the film, "Virgin sacrifices" usually involve bananas, whipped cream, cherries or chocolate sauce used in whatever silly, raunchy way the fellow leading it can devise.
Hot Shots!: Topper and Ramanda sit in front of an open refrigerator, eating. First there was a grape, after a while, a pizza slice, and then it gradually progressed to Topper using Ramanda's stomach as an over and cooked eggs and bacon. All the while, Ramanda looked like she was enjoying it. It gets better. At the end, he holds up two rashers of bacon at her suggestively. But she smiles coyly and lifts up two enormous steaks.

Don't forget Nanny Ogg's cookbook, The Joye of Snacks, containing recipes which are blamed for all sorts of indecorous goings-on (all off-screen, so we never find out exactly what makes "Bananana Surprise" so surprising. The chocolate pudding, however, is shown to act like an Aphrodisiac, making 2/3 of the men that eat it very hot around the collar and desperate to run off for buckets of ice water (and the other 1/3 goes ramrod straight and completely rigid). The only one unaffected is the Big Eater, on account of it 'not touching the sides' in Granny Weatherwax's words.
"Maids of Honor?" "Welllll... they starts off as Maids of Honor... but they ends up as Tarts."
Black Star Rising by Frederik Pohl takes a rather unusual approach to this trope. "Comrade, do you have a fascination with eating bananas, carrots, and juicy red sausages? Then comrade, you can be certain that to your work and study regimen we will be adding plenty of cold showers."
The Bronze Horseman by Paullina Simons. The protagonists Meet Cute when the man (a soldier on patrol) sees the woman eating an ice cream at a bus stop and is instantly smitten by her.

Jon Stewart: [watching Stephen eat Crazy Bread] Oh, that is disturbing!
Firefly: The un-aired original Pilot had Kaylee (Jewel Staite) eating a strawberry in such delight that her eyes roll back in their sockets. A toned down version was put into the later episode "Shindig". Lampshaded in the DVD commentary for the pilot.
Parodies of Nigella Lawson's cooking shows. Nigella herself just occasionally tastes things, while coincidentally being good-looking, but comedians tend to blow it out of proportion.
Bottom: Rik Mayall didn't even need an excuse to get pervy: "I could have been watching Sophie Grigson peeling a banana, or washing a cucumber..."

In an episode of That's So Raven where Raven eats a 3-foot-long hot dog and Eddie comments how tight his pants are. The "joke" is supposed to be that he's eating so much junk food that he's gaining weight, but to anyone outside the show's intended demographic, it takes on a whole new meaning.
Tipping The Velvet: an early scene in the involves the heroine hand-feeding her eventual lesbian lover a raw oyster. There is exactly as little sub- in the text as you might imagine.
Sugar Rush: Les Yay: there are numerous close ups of Sugar eating hot dogs and the like extremely suggestively. It's not just in permanently horny Kim's mind!
Hell, watch the Anger Management episode of Zoey 101 and tell me that Lola eating the bowl of nuts doesn't fall under this trope.
There was an act on the original show called "Have You Got A Nickel?", much better and more appropriately known as "The Popsicle Twins". Two girls just sat on stage in shorts and t-shirts and suggestively sucked on Popsicles. The audience loved it; the judges, not so much. They weren't gonged because Jaye P. Morgan was the only judge that approved, and she physically prevented the other two from gonging it. She stated "That's how Igot started in show biz!" It was apparently that was put in just to be censored, so that the censors would be distracted enough to let other real acts sneak by, and it was let through unexpectedly.
Also appeared in some manner on the new Gong Show, in which a lacklustre musical group had a Sexy Schoolwoman sucking on a lollipop whilst they performed (and indeed, the song included lines precisely to this effect such as "suck my lollipop, baby")
Oz. Simon Adebesi's prag is seen doing this with a banana during a party he's throwing in his Luxury Prison Suite.
Star Trek: Voyager. Jeri Ryan (playing the Doctor inhabiting Seven's body) had an orgasmic response to eating a New York cheesecake, as 'he' has never tasted food before. Given that Jeri Ryan had to fit into her skintight catsuit week after week, the pleasure was undoubtedly not acted.
Bloodsucking is repeatedly used in this way throughout.
In the episode "Fool For Love", Drusilla (a vampire) sucks on Spike's bloodstained finger after he kills a Slayer. As Slayer blood is supposedly a powerful aphrodisiac, this might also qualify as foreplay.
In the least subtle example, Riley got sucked off (his wrist!) in a House of Vampiric Pleasures, with the camera angle and sound effects making it rather... confusing at first just where the sucking was taking place.
When Buffy meets up with Angel in the crossover episode "I Will Remember You" they are shown in bed after a make-out session with Buffy sensuously eating chocolate and licking split peanut butter off Angel's chest.
One episode of Frasier includes the title character eating a frozen treat with a friend of his, a girl he had a crush on in high school. He says to her, "There was a time when I'd have paid a thousand dollars to watch you eat a popsicle." Then she bites it off.
The Sarah Connor Chronicles. Cameron. Potato chips, and later, pancakes. When she's eating the pancakes, she's staring at Derek the whole time, and ends it with a pronounced swallowing.

Inverted and parodied on the Saturday Night Live sketches featuring Kristen Wiig as a sexy redhead named Shana. On the first sketch (which appeared on the season 34 Christmas episode hosted by John Malkovich), she tries to eat a banana suggestively — and ends up gnawing at it like a dog with a raw steak. The second sketch (on the season 35 episode hosted by Charles Barkley) had Shana suggestively suck cream off the top of a mug of hot chocolate. She keeps coughing and spitting it out. The third (on the season 36 episode hosted by BryanCranston) had Shana trying to suggestively drink a protein shake, only to spit it back in the cup.
Played straight in this sketch from the season 30 episode hosted by Luke Wilson, in which two guys (played by Luke Wilson and one-season feature player Rob Riggle) on a double date with their girlfriends (Amy Poehler and Maya Rudolph, who coincidentally starred with Luke Wilson in the film, Idiocracy) end up alienating their dates when their dares to taste what's on the appetizer platter devolves into a Ho Yay-laden Erotic Eating session.
The video for "Angel in Disguise," a 1984 country No. 1 hit for Earl Thomas Conley. Near the end of the video, several exotic models are seen eating various food items – usually, fruit – in an erotic manner, with a focus also on Conley's reaction.
Escape The Fate's "Situations" video. Actually, the whole thing's really three minutes and thirty-two seconds of Fanservice, but one digresses.

Played spectacularly, hilariously straight (well, kinda) in the Bloodhound Gang's video for "Foxtrot Uniform Charlie Kilo."
Annie aime les sucettes, written by songwriter and professional lech Serge Gainsbourg for 18-year-old France Gall in 1966. It's about a girl who likes lollipops and, of course, the lyrics are laced with double entendres. Gall famously didn't understand the song's second meaning and sang it innocently. Only after Les Sucettes caused a scandal did she realize what she had sung.
Note that the song's title can be translated as Annie likes suckers.
The music video for the Wet Spots' song "Labia Limbo" consists almost entirely of this, without the smallest trace of subtlety, either.
The music video for INXS's "The One Thing" also features lots and lots of (messy but) suggestive eating, including some rather memorable scenes with a woman eating a fig.
The music video for Melodies by GAM has a rather long sequence where the two girl feeding each other breakfast which is made to look really sexy although it doesn't include any of the foods usually associated with this trope.
Carlin: As long as I'm being a complete pig up here, let me ask you guys a question. Are you ever able to watch a woman eating a banana and NOT think about a blowjob? I can't do it. And I know why: I'm a sick, evil fuck! I admit that! I can't do it! Eating a banana, eating a pickle, licking on an ice cream cone. I'm thinking to myself "LOOK AT THE TONGUE ON HER! WOW!" So ladies, be careful when you're standing out in front of that Häagen-Dazs. 'Cause God damn it, we're watching. And God damn it, we're thinking!
Dangerous Beauty: In the musical adaptation of the film, when courtesan Veronica is asked how she manages to capture the hearts and loins of every husband in Venice, she picks up a banana, deep-throats it, and then pulls it out whole. Then she spouts some crap about education and how men admire powerful women, but screw that, it's clear which way the wind is ahemblowing.
Bayonetta features suckers that factor as the series mushrooms (natch). Surprisingly subverted in that said suckers resemble Dum-Dum brand suckers as opposed to the exaggerated Blow-Pop or carnival novelty brands Then again, if you can make eating small suckers sexy, then that's impressive. The lollipops might be small on purpose, to fit with the whole dominatrix theme.
At the beginning of the game, Bayonetta briefly licks a lollipop that is thrown to her, and she licks it in a very...suggestive manner.
Agarest Senki will always have at least one case of sexy banana eating.
In Champions Of Norrath a well-endowed and near-topless vampire maiden sends you on a mission to fetch her a plant that can act as a substitute for blood sustenance. Once she has it she devours it in front of you with orgasmic pleasure.

RolloT: (while trying to cut his neck with his pass) Can't UNSEE!
This pretty much became a running gag for LordKat; his final appearance on the show was a cameo in their The Last Airbender review where he appears shirtless and holding a banana, only to have Y Ruler of Time slam the door in his face.
In this (at 10:30) travel v-log, Benzaie does this to Linkara with the help of some special effects.
Todd in the Shadows, in his review of the song "Carry Out", ate fast food very suggestively indeed. He ended up accidentally smearing himself with mayonnaise.

In I Am Not Infected Hartley gets Amanda a popsicle, which she proceeds to eat in the most suggestive way possible. How he thought this would help their uncomfortable situation is unclear, but no one ever accused Hartley of making any brilliant plans.
Two of the Valentines given out during the Valentine's Day '09 event have characters holding hot dogs, clearly about to engage in this trope.
Even the back-to-school event is not exempt from this. Behold, the discussion about bullying and humiliation.
Gino Gambino: I went to a private boarding school, so we all had to change into our pajamas in the dormitories. All the other boys used to make fun of my sunken chest. One time they held me down and took turns eating soup out of it. How did I deal with it? Oh, mostly by crying, I guess.
The Von Helson sisters participated in the Pie Hard pie-eating contest event. The image used for successfully feeding the twins pie was an obvious manip of the twins' seduction from '07, with the addition of... suggestive splatters of pie filling.
There was a Running Gag for a while during announcements for new items, where one of the avatars would be holding the hotdog item or the image of it would be sneaked in some other way, in a clear reference to this trope. It later got officially referenced outside the item announcements with the Valentines' example above.
Tales of MU: The first book has Puddy grabbing a donut specifically for the lesbian version.
The short film Filthy Food, with not the smallest trace of shame or subtlety.

Used in The Boondocks in the episode "Guess Hoe's Coming to Dinner", when Cristal suggestively licks whipped cream off her fingers while moaning, then whispers "It's edible."
Parodied in Metalocalypse, where Murderface explains this as why he refuses to eat sausages, bananas and other similarly shaped food items. He'll also refuse to eat them if they are sliced, because of the castration metaphore.
Later in the episode, when the band is hiding in a dark closet, the lights are turned on to reveal Murderface sucking on a sausage.
Parodied/Lampshaded in Family Guy when Death sticks a whole chicken leg down his throat and sucks the meat off the bone, explaining this "talent" by saying "...I did some films in college I'm not particularly proud of..."
Played with/parodied in a recent episode. Stewie chastises Lois for not slicing his banana: "What am I supposed to do, just stick it in my mouth —well, hello!"
A parody of the 9 1/2 Weeks scene, where Lois sensuously feeds Peter a strawberry, and he responds by shoving a huge watermelon slice into her face.
Also in American Dad, when Roger claims he knows how to teach another character how to please her man then swallows a whole banana. When he notices people staring he hurridly explains that he wasn't making a point, he was just hungry...
Played for laughs when American Dad deconstructs this in "For Whom The Sleigh Bell Tolls. 2 women invoke this trope and one does better then the other, resulting in the later being offended.
Mandy also does this with a lollipop when trying to allure the one-time character "Piff"... you know, so she can crush him.
Both Kim Possible and Velma Dinkley did this with a serving of nachos, cramming the food into their mouths and swallowing the job lot barely chewed, throats bulging with effort. It was all innocent and an attempt to just be one of the guys, but certainly those scenes set some YouTubers looking for erotic screen captures.
Parodied when Grampa and Beatrice flirt by consuming pills in a suggestive manner. Which in itself is a parody of the famous scene in Tom Jones.
Also on the episode where Selma tries to find a man as per her Aunt Gladys's last request, during a date video taping, Selma chews on a (lit) cigarette and sticks out her tongue where the cigarette is now tied in knots (the only reason she can do that without feeling pain is revealed on season three's "Black Widower" where she told Sideshow Bob that a childhood accident where a bottle rocket went up her nose permanently destroyed her sense of taste and sense of smell.
Then again, so does smoking for a long time, which also happened to Selma when she was a kid, according to the season two episode "Three Men and a Comic Book" in which Patty and Selma take up smoking after telling Marge that she can do their chores for them so she can raise money for an Easy Bake Oven.
And inverted into Fan Disservice on the Treehouse of Horror episode "Homer^3" (the one where Homer is stuck in a 3D world after trying to hide from Patty and Selma). Patty and Selma find out that they can suck the many-days-dead conches and hermit crabs out of their shells to clean their seashell collection.
After eating dinner, Marge and Ned Flanders both eat strawberries dipped in whipped cream more erotically in "The Devil Wears Nada". Even the promotional artwork for the episode shows this.

Clone High: Joan of Arc disguises herself as a boy to be on the school basketball team. Cleo attempts to seduce her with Erotic Eating, unaware of who she really is, by using a banana and some milk.
