->''"Should I explain to you the meaning of a closed door in a whorehouse?"''
-->-- '''Tyrion Lannister''', ''Series/GameOfThrones''

A couple is about to have sex, or are in the midst of the act, but another person interrupts somehow. They have to stop to deal with the interruption. This trope can be played for comedy, drama or both. Can often lead to a RelationshipReveal. If they choose to keep going, it's CoitusUninterruptus. If they try and keep things secret (if there is a knock on the door), it could lead to a ClosetShuffle. A subtrope of MomentKiller.

Often followed by a "Don't you people know how to knock?", because [[YourDoorWasOpen no one ever locks their door]] when they're getting intimate.

Compare to CaughtWithYourPantsDown for the [[ADateWithRosiePalms solo]] version of the trope. A supertrope of PrimalScene and ParentsWalkInAtTheWorstTime. SisterTrope to SorryToInterrupt.

[[folder:Anime and Manga]]
* This happens to Lupin and Fujiko, in ''Anime/LupinIIITheSecretOfTwilightGemini'' Just as they're getting started, Sadachiyo and his men burst into their hotel room to assassinate Lupin, forcing him to bail in his underwear; which leaves Fujiko stark naked with nothing but a bedsheet to defend herself!
** Averted the second time 'round, [[spoiler: which takes place in a Morrocan police station! Lupin scores.]]
* Happens near the beginning of ''Vitamin''. The protagonist's boyfriend forces himself onto her while they're in school, and a classmate sees them.
* ''YuugenKaisha'' has a scene like this, in incident file 03. Detective Karino drops by Nagasuki's office to question him, not knowing things were heating up between Nagasuki and his [[SexySecretary secretary!]] So when he opens the door, he gets an eyefull, though the audience [[SexyDiscretionShot doesn't get to see anything.]]
* Invoked in ''VisualNovel/SchoolDays'' (adapting a possible event from the original visual novel). [[spoiler: Sekai's friend Nanami Kanroji and her sempai/boyfriend try to get some "quality time" in the middle of a school festival, so they end up having sex in the rest area booth. They're not interrupted but they ''are'' filmed by Otome's GirlPosse, who are such ''nasty'' bitches that they ''show the tape to the whole school''. The upperclassmen think this is funny, but poor Nanami has an HeroicBSOD.]]
** Double invoked, as [[spoiler: almost immediately afterwards, we see that Makoto was caught on tape too... having sex with ''Otome''. And this is how Sekai learns that, after she and Makoto cheated on Kotonoha, ''she'' is now the one cheated on.]]
** The first part [[AdaptationExpansion is expanded on]] in other media (namely, the game's UpdatedRerelease), and it's even worse. One: [[spoiler: Nanami and her boyfriend weren't filmed by Otome's GirlPosse, but by Nanami's sempai and rival Chie Ashikaga; she releases the video out of spite against her.]]. Two: [[spoiler: we see that ''they're actually quite kinky in regards to sex'' (into master/servant, sex roleplaying, etc.)]] No wonder [[spoiler: poor Nanami completely shut down: not only she and her boyfriend were caught doing the deed, '''but their kinks were exposed to everyone in the school'''.]]
* In ''Literature/FromTheNewWorld'', 12-year-olds Saki and Satoru end up engaging in what is basically sexual foreplay as a response to the stress of getting captured, as humans in their time have been conditioned to use sex to relieve tension, modeling after the society of Bonobo chimps. It is Saki herself (much to Satoru's frustration) that puts things to a halt upon remembering this, resolving that "we're not monkeys".
* In FushigiYuugi, Suboshi needs to talk to his boss Nakago and goes into his tent. Nakago is having sex with his and Suboshi's fellow Seiryuu Senshi Soi...
[[/folder]]

[[folder:Fan Works]]
* PlayedForLaughs in the appropriately titled, [[http://m.fanfiction.net/s/5863602/2/ This Closet's Lock is Broken]], when Soifon accidentally bursts in on [[SexyMentor Yoruichi]] while she's having sex... with [[{{Sexbot}} a mod soul designed to look and act like her!]]
* In a chapter of ''Literature/HarryPotterAndTheDeathlyHallows'', Ginny leads Harry to her bedroom (with the door closed) to give him a birthday present to "remember her by", and they begin to kiss very passionately, but are interrupted by Ron barging into the room. There are many stories that speculate that, had Ron not interrupted, Harry and Ginny would have had sex.
* This trope probably scars [[LuckyStar Kagami]] for life in ''[[FanFic/StarsAbove Stars Above]]'' [[spoiler:when she accidentally walks in on Tsukasa and Miyuki.]]
* ''Fanfic/MyImmortal''. When [[DracoInLeatherPants Draco]] and [[MarySue Ebony]] have sex in the Forbidden Forest, Dumbledore barges in out of nowhere, yelling "[[AtomicFBomb WHAT THE HELL ARE YOU DOING YOU MOTHERFUKERS!]]"
* Empath in the ''Fanfic/EmpathTheLuckiestSmurf'' story "Days Of Auld Lang Smurf" interrupts Papa Smurf's private moment inside the Imaginarium with a recreated fantasy version of his wife just as they were about to kiss. Of course, Empath doesn't know that this is what Papa Smurf was doing with his time away from the other Smurfs until he saw Papa Smurf in a bathrobe emerging from a Smurf house.
* ''FanFic/TheInfiniteLoops'' love to play this for laughs. Taken to an extreme where five separate people walk in on [[MyLittlePonyFriendshipIsMagic Spike and Rarity]], apparently during the same loop, and react completely differently to the situation.
* ''Fanfic/TheWrongReflection'' has Fleet Admiral Riker call up Eleya to give her some info and orders right when she and her boyfriend are in the middle of foreplay.

[[folder:Film]]
%%* RunningJoke in ''ShakespeareInLove''.
* In ''Film/CemeteryMan'', Francesco Dellamorte and his mystery woman make it on top of her husband's grave, at her request ("He would have liked to know.") Unfortunately, in this particular cemetery the dead are prone to rise seven days after burial - her husband digs his way out, catches them mid-act and promptly takes a bite out of his wife's arm, whereupon Francesco impales him with a cross.
* The ''Film/JamesBond'' film ''Film/DiamondsAreForever'' has a scene where Bond (Creator/SeanConnery) takes MsFanservice Plenty O'Toole back to his room where he gives the obligatory strip down so they can have sex but when she goes into the bed room to dispense with what little remains of her attire (high heels, flimsy see through pink panties and a fancy necklace) while Bond tosses her low cut purple satin dress on a chair and turns on a light... only to find himself being held at gunpoint by a bunch of mooks. The mooks then proceed to toss the basically naked Plenty out a window while she screams in humorous sexually humiliated protest, only to land in a pool, downgraded from ShamelessFanserviceGirl to ReluctantFanserviceGirl.
* In ''Film/HotTubTimeMachine'' Adam, Nick and Jacob walk in on Lou having sex with Adam's sister, meaning Jacob [[PrimalScene witnesses his]] [[{{Squick}} own conception]]... sort of. When he tries to attack Lou, he disappears. CoitusUninterruptus has to ensue to ensure Jacob lives.
* RunningJoke in ''Film/GoingTheDistance'' too -- from Dan DJ'ing Erin and Garrett's first hook-up, to her sister walking in on them having sex on her dinner table... and her husband eating a midnight snack to them walking in on her sister and her husband dry-humping.
* In the Japanese movie ''Film/TheEel'', the protagonist finds his wife having intercourse with another man and kills him right then. He spends eight years in prison; his life right after release is the actual story.
* Happens in the British film ''Film/SirHenryAtRawlinsonEnd'' when in a flashback Seth Onetooth finds his wife Rosie carrying on with Henry's brother Humbert in the bushes. This leads to Humbert "accidentally" getting shot by Henry, and explains why his ghost cannot rest until it has found trousers.
* In ''The Secret of My Success'', Brantley (MichaelJFox) ends up having an affair with his boss's wife [[spoiler: [[http://www.youtube.com/watch?v=tfYqWagt-14 who turns out to be his aunt!]]]], Vera. When she comes to his office, looking for seconds (which is one-sided this time), they get busted when [[http://www.youtube.com/watch?v=Rz04kVAI3bs his uncle shows up unexpectedly, to talk to him.]]
* In ''Film/SchindlersList'', Schindler is having sex with his mistress, when he's informed that his accountant, Stern, has been mistakenly put on the train that takes Jews to the death camps. Schindler manages to save him just in time.
* In ''Film/MakeTheYuletideGay'', Gunn and Nathan are in Gunn's room stripping down to have some fun time, when Gunn's mom comes in to make sure the boys have enough sheets for their beds.
* ''Film/FriendsWithBenefits'' has Jamie's mom walking in on Dylan and Jamie in the middle of the act. They are more freaked out than she is.
* In ''[[Film/{{DEBS}} D.E.B.S.]]'', Amy and Lucy's relationship is exposed when the other members of D.E.B.S. burst in on them in bed together.
* The end of ''Film/DieHardWithAVengeance'' involves ''the hero'', John [=McClane=], interrupting Simon, the villain, as he's about to get intimate with his wife. The normally stoic woman suddenly gets very angry at [=McClane=].
* ''Film/StarTrekIntoDarkness'': Don't think Kirk can top Uhura interrupting his session with an Orion woman in her dorm room? Kirk sees your sexual shenanigans and [[RefugeInAudacity raises you two]] Caitians who are annoyed Star Fleet is paging him.
* Near the start of Brian de Palma's ''Body Double'' the unemployed actor hero goes home to find his girlfriend's clothes strewn around the apartment and thinks that she's planning something special for him. When he gets to the bedroom he finds out she got started without him and with someone else.
* ''Film/FridayThe13th1980'': Barry and Claudette have engaged in foreplay and Claudette's shirt is totally unbuttoned when Pamela Voorhees sneaks in on them. She kills Barry onscreen with a knife to the stomach and offscreen, Claudette in the neck.
* ''Film/{{Lolita}}'' (1997). Humbert is kissing his underage stepdaughter when a police car roars up on them, much to his alarm. Fortunately the cop is more interested in asking if they've seen another vehicle he's pursuing, and fails to realise what's going on.

[[folder:Literature]]
* Captain Armand Pahner walks in on two of his sergeants (Eva and Julian) in the ''Literature/PrinceRoger'' series. Additionally, Julian deliberately arranges for this to happen to Roger and Despreaux on multiple occasions. By monitoring the biometrics in her combat suit (specifically pulse and blood pressure) he can tell when they [[SlapSlapKiss are arguing and when they... aren't]].
* ''Literature/ASongOfIceAndFire'':
** A large portion of the drama is sparked by [[spoiler: Bran seeing Cersei and Jamie Lannister having sex]].
** The trope is PlayedForLaughs several novels later when Jaime barges into Lord Bracken's tent unannounced, to find him screwing a CampFollower.
-->'''Bracken:''' I fear I did not hear your coming, my lord.\\
'''Jaime:''' And I fear I've [[DoubleEntendre interrupted yours]].
[[/folder]]

[[folder:Live Action TV]]
* In ''Series/{{Smallville}}'', Clark has the unfortunate habit of crashing in at the wrong time, although the scenes are usually relatively innocent.
-->'''Lois''': (entering [[spoiler:Chloe and Jimmy]]'s apartment) You know what Lois likes to see when she comes home? Pants. Pants on everyone.
* Abby has to hide under Brody's bed when her drunk brother Richie turns up for a midnight visit in ''Series/AgainstTheWall''.
* ''Series/LipService'', in the fourth episode when the interruptor turns out to be [[spoiler: the husband of one of the women who is hoping to watch the two of them have sex]].
* Running gag in ''Series/SixFeetUnder''. Nate and Brenda get interrupted twice, first by Brenda's brother, then [[ParentsWalkInAtTheWorstTime Nate's mom]].
* ''Series/GameOfThrones'':
** The last scene of episode one. With horrific and long-reaching consequences.
** PlayedForLaughs when Jamie Lannister walks in on his brother at a brothel in Winterfell and tells him to hurry up, then proceeds to send in more prostitutes in order to hurry him up.
** This almost becomes a RunningGag in season 4 when different people keep interrupting Prince Oberyn Martell to discuss politics when he's trying to set up an orgy in a brothel.
* PlayedForLaughs in a ''Series/TheBigBangTheory'' episode. Leonard was sleeping with a girl named Joyce Kim and was having sex with her when Sheldon decided to interrupt by knocking on the door. Leonard was thinking of ignoring him, but Sheldon knew he was being ignored. Sheldon then came in to remind Leonard of their Roommate Agreement. Due to its terms, Joyce decided to leave. This was actually a good thing for Leonard as she was a North Korean agent trying to get information about a project he was working for. He even admits Sheldon probably saved him from going to federal prison. Again, PlayedForLaughs, but still.
* ''Series/{{Friends}}'': When Chandler and Monica first get together in London, Joey walks in on them. Monica hides under the sheets leaving Chandler to be forced to pretend to have ADateWithRosiePalms to throw Joey off. This trope then happens to the couple on several occasions over the next few months while they're trying to keep their relationship secret. Even after their relationship is official, they can still sometimes be victims of this trope. After they're married and decide to try having children, they get down to business in a hospital janitorial closet and are interrupted in the middle of the act by Monica's father walking in on them, traumatising all three of them.
* An episode of ''Series/VeronicaMars'' has an (adult) hacker's relationship with a student (minor) at the school being exposed by Veronica and her camera. She even says "It's satisfying to be the interruptus in somebody else's coitus."
* ''Series/CombatHospital'' has Graham interrupting Simon and Rebecca at the undressing-and-foreplay stage with some pretty serious news for Simon. Rebecca hides, then slips out the back.
* ''Series/BoyMeetsWorld'' had a comically extreme example: Cory and Topanga are about to consumate their marriage when the police burst to the hotel suite in and arrest them (because they inadvertently stole someone else's wedding thanks to Eric).
* The ''Series/{{Eureka}}'' episode "What Goes Around Comes Around" has Jack walk in on two amorous couples. The first time, it's [[ParentsWalkInAtTheWorstTime Zoe and Lucas making out on his couch.]] The second time, it's Fargo going all the way in the middle of a serious electromagnetic disaster...
* ''Series/{{Chuck}}'' has Chuck and Sarah on the run in order to find Chuck's father, and finally look like they will resolve all that [[UnresolvedSexualTension sexual tension]] after [[ThereIsOnlyOneBed sharing a bed]] at a motel. Chuck steps into the bathroom to get a condom from his wallet, only to find out that Morgan has taken it and left an IOU note instead. He runs out to buy a new one only to be caught by Casey, who had tracked them down. When they get back to the room, Sarah is no longer there, having figured out something was up.
* ''Series/RookieBlue'' has Sam [[spoiler: and Andy]] being interrupted by Sam's boss. Since he is undercover and working for a very nasty drug dealer, this is quite serious and is PlayedForDrama.
* In the pilot episode of ''Series/TwoBrokeGirls'', Max breaks up with her boyfriend after she catches him [[YourCheatingHeart cheating on her]] this way, clearing the way for Caroline to move in; in the second-season episode "And the New Boss", she walks in on Caroline and Andy.
* ''Series/SouthOfNowhere'': How Spencer's family learned that Spencer was gay.
* In ''Series/{{Torchwood}}'', Gwen walks in on [[YaoiGuys Jack and Ianto]] right in the middle of a make-out session in the office.

* ''Series/ModernFamily'''s "Caught in the Act" episode during the second season. All three Dunphy children [[PrimalScene walk in on their parents.]]
* ''Series/BuffyTheVampireSlayer''. Happens several times with Xander walking in on Buffy -- in "Intervention" (actually Spike screwing a Buffy SexBot), in "Gone" (Spike screwing the real Buffy, only she's been turned invisible so Xander just sees Spike acting very strangely) and "Him" (Buffy making out with Dawn's boyfriend on a school desk due to a love spell).
* This is how [[spoiler: Ethel]] gets fired from her job at ''Series/DowntonAbbey''.
* The season 3 opener of ''Series/{{CSI NY}}'' opens with Mac and Peyton being interrupted,sort of-They appear to have just finished and she's laying with her head on his chest-a call for Mac.
** Season 9 has a milder form, Mac is just sitting in the park,holding Christine,when the phone rings. Still a type of intimacy,just not actual sex.
* In ''Series/SpartacusBloodAndSand'', Agron and Nasir are making out in a hallway, where they are supposed to be keeping watch, rather passionately when Mira finds them. [[YaoiFangirl She tells them to go to bed.]]
* In the American version of ''Series/Shameless'' this happens a good deal to Fiona, mostly because she can't find much free time in her personal life because of her PromotionToParent, so when she does have sex it's in awkward, semi-public locations.
[[/folder]]

[[folder:Music]]
* Happens in the Music/{{Warrant}} song "[[IntercourseWithYou Cherry Pie]]":
-->Swingin' so hard
-->We forgot to lock the door!
-->In walks her daddy
-->Standin' six foot four!
-->He said "you ain't gonna swing
-->With my daughter no more"!
* Tone Loc's ''Wild Thing'' has the same thing happen (in this case the girl's ''mother'' interrupts them), but with more benign results:
-->I didn't know what to say; I was hanging by a string
-->She said "Hey, you two, I was once like you and I like(d?) to do the Wild Thing."
[[/folder]]

[[folder:Theatre]]
* In the BBC production of ''HenryIVPart1'', Hal and Doll deliberately create one of these moments. They pretend to be getting hot and heavy so that when the sheriff walks in on them, Hal has a reasonable excuse for wanting to get rid of him as quickly as possible. They don't want him to search the house and arrest Falstaff.
[[/folder]]

[[folder:Visual Novels]]
* Subverted in ''VisualNovel/SchoolDays''. Kotonoha comes to Makoto's house while Makoto and Sekai are having sex and walks in on them. At first it seems like she caught them in the act, but then it's revealed that Makoto invited her there for a threesome.
** As said above, a similar scene on a different route plays the trope straight, and [[spoiler: leads directly to a bad ending.]]
* PlayedForLaughs in ''KatawaShoujo''. In Emi's route, at one point Rin walks in on her and Hisao right after the end of their first sex scene, [[{{Cloudcuckoolander}} requesting to use Emi's window to look at a specific cloud.]] She doesn't appear to notice that Hisao and Emi are both half-dressed (Hisao is topless, and Emi is down to her panties), and leaves when Emi politely asks her for some alone time.

[[folder:Webcomics]]
* In ''Webcomic/MenageA3'', this is a RunningGag. Nearly every time Matt has sex, no matter with [[ReallyGetsAround whom]], someone walks in and interrupts him.
* In ''Webcomic/{{Misfile}}'' Ash and Emily end up walking in on Kate and Harry having sex. Oddly enough Kate is only mildly embarrassed and glad that it was at least someone she knew. Ash on the other hand looks like she could use a jug of {{brain bleach}}.
* The page picture is from ''Webcomic/GunnerkriggCourt'', where Kat and Annie walk in on Kat's parents just at the right time to avoid a PrimalScene. They resume intimacy when the kids leave.

* On ''WesternAnimation/{{Archer}}'' Lana dumps Cyril after walking in on him having sex with Framboise from ODIN.
