Indirect Kiss

I know you didn't wanna kiss me, but when I was taking a hit off that bottle before, I backwashed in it. I mean, like, really big-time.

—McKenas Cole, Alias, s1e13, The Box: Part 2

Issues of physical contact taken to a logical extreme. The surprise is when someone is offered food or drink by someone they like, then realizes that swapping spit residue is apparently somewhat similar to a kiss, indirectly.

Bizarrely enough, a form of this notion, the sharing of a drinking glass with a lover as an intimate act, appears in a treatise on romance by the Roman poet Ovid, making this Older Than Feudalism.

Examples of Indirect Kiss include:

Advertising

This very squickful Hong Kong ad for Tempo tissue paper: a dork picks up a piece of used tissue, with a lipstick mark, from the desk of his female colleague, and treasures it like his own dear life.
This is the reason, according to the Man Law, that men must toast with the bottom of the beer bottles.

Anime and Manga

Rurouni Kenshin has an example that foreshadows Kenshin & Kaoru's future relationship: they both drink from the same sake cup, after which Megumi slyly remarks, "It's as though they're a married couple", eliciting embarrassment from Kaoru & Kenshin's trademark flustered "Oro?".
In Ah! My Goddess, while under the influence of a drug that makes her a bit more "aggressive", Belldandy purposefully sets up Keiichi on the verge of having an indirect kiss with her after she asks him to have a taste of his canned drink. Too bad that it spilled over.
In episode 6 of Chocotto Sister, Choco shares an ice cream with a boy named Kakeru Ishida. As they share it, he thinks "This is an indirect kiss!".
Mysterious Girlfriend X is based on this trope; the Boy is literally addicted to the Girl's sweet saliva, but they've yet to kiss—she sucks on her finger and lets him suck her drool off.
- Used a little bit closer to form in chapter 59 Tsubaki kisses Urabe's photo and then lets her taste his 'drool' so she can feel how turned on he is. Then she has him do it again, and she kisses the back side of the picture, directly opposite his lips.
Parodied (as are all things) in Excel Saga: Watanabe agonizes for some time over whether or not to sip Hyatt's tomato juice, thereby getting his first "indirect kiss". Before drinking it, however, he notes that it's overflowing. It's not all tomato juice; Hyatt presumably vomited blood into it. Later in the episode, it's revealed he was hospitalized after drinking it.
- Although the hospitalization probably came from all the medicine Hyatt added to it when he wasn't looking. She needs a lot of medicine, given her tendency to cough up blood and die at a moment's notice. Factor in that her medicine, once used to leave a trail behind her when she was kidnapped, was eaten by birds... and left a trail of dead birds instead.
Episode 19 of Kimagure Orange Road has Kyosuke and Madoka consciously sharing an indirect kiss on a deserted island. Namely, they share an apple and she chooses to eat from the portion he started from.
Another excellent example of the indirect kiss is in Black Lagoon (pictured above) between Revy and Rock—the "cigarette kiss", in which Revy chains her cigarette from Rock's, after a fight between them, hence, (indirect) kiss and (silently) make up.
- It's also a Slap Slap Kiss, with Revy doing the slapping. And by slapping, we mean "almost blowing Rock's head off."
- And also punching him in the face soon after that, hence the bruise under his left eye.
Happened in Angelic Layer, Tamayo sharing out of Koutarou's bag of chips.
Lucia in Mermaid Melody Pichi Pichi Pitch keeps freaking out about this sort of thing, especially in the chapter when her emotions go out of control while visiting Kaito (anime: influenced by magical item; manga: drunk), until they finally do kiss.
Tsuwabuki in Revolutionary Girl Utena ends up throwing away a chocolate bar that a girl had bitten after contemplating that eating it would count as an indirect kiss. This apparently harmless item later appears in his duel as a symbolic manifestation of Tsuwabuki's desire to grow up.
In FLCL, Kitsurubami unintentionally does this with a drink she was holding for Amarao. She's horrified after she realizes what she's done.
In Dragon Half, Mink has an Accidental Kiss with Dick Saucer; later, her friend Lufa tries to get an indirect kiss with Dick Saucer by kissing Mink.
Parodied in Gakuen Heaven: keeping up the Boys Love spirit that pervades the whole series, the whole cast that consists of varying degrees of Bishonen discuss who was it that used a character's toothbrush, something that would constitute an indirect kiss of the creepy kind. Did I mention that everyone is naked in one of those Hot Springs Episode type of situations? As it turns out a cat was the culprit. Of course.
In Please Twins!, a flustered Miina accepts a can of soda from her love interest Maiku, literally referring to it as an indirect kiss later on.

Done in "The Melancholy of Asahina Mikuru" story of the 6th Suzumiya Haruhi light novel. Mikuru silences Kyon's flustered, mumbled attempts to comfort her by placing her index finger on his lips. She then slowly lifted her index finger and placed it on her own lips. While neither of them outright acknowledge it as an indirect kiss, Kyon's elated reaction and his following thoughts are very much in line with the trope.
- While shooting their film in "The Sigh of Haruhi Suzumiya", Mikuru offers Kyon water from the bottle she's been drinking from. Haruhi immediately grabs it from him.
  - Later at the end of the arc, Haruhi drinks from the same cup as Kyon in a cafe.

Kuroko desperately asks for equal treatment, but Mikoto refuses since Kuroko got the same kind as her.
- Implied but not really dwelled upon in the related A Certain Magical Index, when Mikoto drags Touma into pretending to be her boyfriend. They both get hot dogs, and are distracted after each has taken a bite. When they turn back to their lunch, they don't know which belongs to whom. Touma doesn't care, since they both got the exact same thing, but Mikoto quietly obsesses over the idea. Attentive viewers note that each did in fact end up with the other person's hot dog.

- Hinagiku gets flustered over one from a coffee cup in chapter 283.
The Last Kiss between Riki and Iason Mink in Ai no Kusabi was like this, with them pressing the tips of their cigarettes together as they share both a Last Kiss and One Last Smoke right before Iason bleeds to death after having his legs cut off and the place they're in blows up. Together in Death, indeed..
Shizuku of Kämpfer intentionally invokes this. Asking Natsuru to pass her first the soda, then two cups. She pours into both, picks one up, but only kisses it. Then she offers it to Natsuru. The entire crew is there for this, and they all act suprised, except Natsuru himself, who tries to back away. Eventually Shizuku just does away with the indirectness.
- Not to mention shortly after, when Akane considers kissing Shizuku because it would be an indirect kiss with Natsuru.

Comic Books

A possible variation usually occurs with Rogue of the X-Men. Since she can't touch someone without draining the life out of them, she will usually do something like put her (gloved) hand over their mouth and kiss that instead.

The second episode of the Due South two-parter Mountie on the Bounty: Fraser gives Ray Kowalski air via mouth-to-mouth "Buddy Breathing" while underwater in a sinking ship. Although there is direct contact, this is still an Indirect Kiss, as the intent was the exchange of air rather than romance. Fraser calls it "standard procedure", and when Ray asks if anything has changed between them, Fraser assures him that no, it hasn't. This scene is also a good example of Ho Yay.
In Friends, Chandler buys Monica an engagement ring. Phoebe happens to be holding it when Monica walks in. To keep it out of sight, she quickly puts it in her mouth. When Monica leaves, she gives it back to Chandler who then has to hide it in his mouth too when Monica enters the room again. Once she leaves, Phoebe teases Chandler: "We're practically kissing."

Considering the direction that the series took regarding their relationship as it progressed, this is remarkably subtle.

Literature

A rather strange example of indirect sex occurs in John Donne's poem "The Flea". A man tries to get his girlfriend in the mood but she's having none of it. He pulls a tick/louse/some bloodsucking insect from his pubic hair and puts to her skin so that it feeds. He then argues that since their bodily fluids have now mixed in the tick it's like they've already had sex, so they might as well do it for real anyway, because it makes no difference. Needless to say, she squashes the tick.

Of course, this is also a prime example of Get Thee to a Nunnery, as the poem repeatedly mentions "sucking". Back in the day, the long "s" would have resembled an "f".

In Shards of Honour of the Vorkosigan Saga by Lois McMaster Bujold:
- The Hero and Heroine give CPR to another character, and at one point they have to change because her arms are tired. She has a silent ironic laugh at the "parody of a kiss"
- Done again and heartbreakingly in the same novel when the heroine decides to send the hero a physical letter rather than an electronic one because "it was as close to a touch as they could come."
This trope is explored at some length in Longus' Daphnis and Chloe, owing to the woeful sexual inexperience of the two titular characters. Being written in the 2nd century AD makes this, well, rather old.
In Kelley Armstrong's Exit Strategy, Jack smokes constantly while Nadia has quit smoking. Jack lets Nadia take puffs off his cigarette, since she won't smoke a full cig but she can rationalize sharing as not really smoking. Neither of them ever discuss it, but the third point in the love triangle notices and gets nasty towards Jack about it. After it's pointed out to her, Nadia is uncomfortable with the intimacy of sharing a cig.
Not a straight example of this trope, but possibly an early proto-form of it: in Rainbow Valley, Rosemary West can't help but notice that Rev. Meredith put his lips on the same spot of a tree-bark-cup that she did when she drank from it earlier, and thinks about how she was told that when that happened, the destinies of the two involved will be linked together...
In The Name of the Wind Kvothe and his love interest share an apple, which he explains is, "as close to kissing, if you've never done it before," or something to that effect.
In Midnight's Children, the narrator describes seeing a Bollywood movie that got around the conservative social conventions of the day by having the hero kiss an apple, then pass it to the heroine so that she can kiss the same spot. For the pre-teen narrator it ends up being more erotic than if they had simply kissed in the first place.
