Caught with Your Pants Down



"While the wee wife's away, a word on the subject of onanism: in this house, we don't masturbate. It's not a very pleasant thing to do. One hates to imagine young Chloe or Radclyffe scampering down the stairs of a Saturday morning, only to find you, double-bent on the sofa, pumping your fist!"

- Harvey Denton, The League of Gentlemen

A subtrope of Cringe Comedy. A character, thinking they are alone, decides to indulge in a little self-pleasuring only to be interrupted by their partner, parent, sibling, best friend, The Vicar (for maximum laughs), whatever. Seriously people, next time - lock the door.

Usually Played for Laughs, although it's not impossible to see it Played for Drama. For when it is not a solo situation, see Interrupted Intimacy.

Anime and Manga

 * Many, many a start of the intimate portion of That Wasn't There Before Hentai Futanari Doujinshi in a particularly embarrassing example.
 * Or just Hentai in general...
 * Happens to Satou when his mother walks in on him in the Welcome to The NHK manga, with the added embarrassment that he's looking at Hentai at the time. And has set up a customized rig for internet porn in his parents' spare bedroom, complete with a leather massage chair.
 * Alice learns the hard way in Serial Experiments Lain that internet surveillance is more intensive than she thought...
 * F3: Frantic, Frustrated & Female opens with this trope, as a girl unable to climax has her big sister walk in on her.  The manga goes for 3 more books after this, the whole thing never gets resolved.
 * Happens in Code Geass (the infamous 'Table-kun' incident). Fortunately for Nina, Nunally couldn't see what was happening and is too innocent to realize what was going on. Probably. Hopefully.
 * An implied near-miss happens to Maho Nitori in Wandering Son. She and her brother Shuuichi sleep in bunk beds and at the end of chapter 39 when Shuuichi is woken up by creaking sounds and looks to see a panicked Maho out of bed asking if he'd heard. As she leaves the room, her pajama bottoms have a dark stain. The situation implies either this trope, an aversion of No Periods, Period, or, what the heck, both.
 * From the looks of it, it was probably a period stain; she also mutters something about whether had mom had "any", implying tampons or pads. Though she did act a bit too suspicious and embarrassed.
 * My Balls. Subverted when
 * In the manga of Bokurano, it's implied that Dung Beetle catches Anko like this at one point. She's none too happy about it.
 * invokes the trope before fighting.
 * Light Yagami uses hidden dirty magazines as an excuse for making sure other people haven't entered his room. When L, his father and his sister Sayu see this, they don't see the Death Note, thankfully, but they do accuse Light of being a pervert (L even remarks it's perfectly natural for someone his age).
 * In the 2nd Boku No Pico OVA, it's used as a plot device: Chico peeps through a crack in the ceiling to watch his sister schlick, (he doesn't even know what she's doing), and Pico, having experience, teaches him all about sex. In the 3rd OVA, Pico walks in on his new friend Coco masturbating, gets aroused by it and masturbates while watching him masturbate. Unfortunately, the curtain falls, blowing Pico's cover. It's a little bit creepy because.
 * A double entry from Haruhi Suzumiya when Kyon was closing the pictures of Mikuru's chest with star-shaped mole: He forgot to close the folder which had the name of "Mikuru" written as the folder name. It's busted by Haruhi spotting Mikuru having some "fun" with Kyon - which did not translate so well for the world.
 * Yuria 100 Shiki pretty much runs on this trope.
 * At least, it does with the titular Yuria. The slightly more advanced Juria poses as an inanimate sex toy, so she's more likely to invert the trope, pretending to be "in use" by her owner to get out of situations that would reveal her true nature.
 * In Bible Black it's more like caught giving a Facial....and in front of your best friend who secretly has a crush on you to top it all off.
 * Overlaps with Coitus Uninterruptus because it wasn't exactly like he could stop by that point.
 * Great Teacher Onizuka is a 22-year-old virgin living on the roof of the middle school where he teaches. He works off the frustrations that come with being a Chivalrous Pervert, so it's no surprise that he's been literally caught with his pants down.
 * Invoked in School Days, when
 * Double invoked, as
 * In one chapter of the Gunsmith Cats manga, Minnie May is masturbating to a photo of her missing boyfriend Kenny when Becky walks in on her.
 * The plot of Onani Master Kurosawa begins with this.
 * In a chapter of Kodomo No Jikan, Rin masturbates at school, and is embarrassed when she thinks her teacher has caught her in the act.
 * In Urotsukidouji Nagumo is caught by the school jock Ozaki masturbating in the ball pit, he then holds him up by the back of his shirt and shows the entire student body his erection.
 * In chapter 337 of Mahou Sensei Negima, Eva walks in on Chachamaru winding herself up (technically, powering self up, but it has VERY similar effects to sexual arousal) while calling out Negi's name. Hilarity Ensues since Eva is very amused and pleased.
 * Momo in To Love Ru Darkness gets caught by her twin sister playing with her tail. Luckily for her, Nana is too innocent to realize what Momo was doing.
 * In Oniichan no Koto Nanka Zenzen Suki Ja Nai N Dakara Ne, Shuusuke was completely nonplussed when Iroha told him how much his masturbates (5 times a day!), down to which hand he uses. It turned out she snooped him through a telescope.

Comic Books

 * In the XXXenophile story "Touch Tone" a woman is indulging in some phone sex late at night at work when the guy she thought was on the other end of the phone walks into the room.

 * A short comic by Phoebe Gloeckner has a Czech punk girl caught not once but twice when she has sex with her punk boyfriend in public. The second time, her mother happens to be among the people witnessing this. Big Oops.

Fanfic

 * Before the Silver Doe by Metafrantic takes this to ludicrous levels. First, Hermione walks in on Harry masturbating. Then, Harry walks in on Hermione masturbating. Then Harry masturbates to the thought of Ginny masturbating in the same way that he had caught Hermione masturbating. Then Hermione decides to watch Harry masturbate. And THEN Harry watches Hermione masturbate with the latters consent, and ends up masturbating to Hermione's masturbation. It becomes rather funny after a while.
 * The start of the "Vs. Ponyville" arc in Progress sees Celestia finding Luna in the library, asking why, and not getting a straight answer. She figures it out within seconds: Luna walked in on Sundance (her roommate) and Hoyden (Sundance's coltfriend) mating (capping her long streak of luck walking in on them being romantic). In order to help avoid awkwardness, Celestia assigns Luna to duties that require her to leave Canterlot for a while.
 * In Naruto Veangance Revelaitons, Sasuke catches Ronan sucking his own penis while looking at a picture of Sakura, prompting Ronan to shoot him with his blue light in retaliation. Later on, Ronan masturbates to Taliana raping Sakura until Taliana sees him, at which point he shoots her in the vagina and frees Sakura.
 * In Stars Above,

 * And in The Naked Mile

 * Bonus points towards WTF: That woman was Lorri Bagley, Farley's then-girlfriend in real life.
 * Fast Times At Ridgemont High - "Doesn't anybody ever fucking knock anymore?"
 * This scene was parodied in the "Stacy's Mom" video by Fountans of Wayne, with the added fillip that Stacy walks in on the boy, thinks he's doing it for her, and walks away happy. As the song's title suggests, it's not Stacy he was picturing.
 * Parodied by Not Another Teen Movie: the teenage girl tries to have some "alone time" with a dildo on her eighteenth birthday, when her parents, grandparents, siblings, family pets, pastor, and the girl scout troop she mentors enter in quick succession.
 * Donnie Darko's psychiatrist hypnotises him to encourage him to talk more openly, only for Donnie to go off on a tangent about Married... With Children and try to masturbate to Christina Applegate.
 * In You, Me and Dupree, husband and wife, Carl and Molly, catch Carl's best friend, Dupree, masturbating in their living room to a porno movie. Unfortunately, Dupree didn't put away a box labeled "camping gear" where he got the tape from which contained Carl's entire collection of Asian porn movies which his wife forced him to toss.
 * Subverted in Theres Something About Mary when Ted is caught looking at Mary out the window and they assume he is masturbating. His attempts to cover up lead to hilarity, word-of-mouth, and box office success.
 * Plus he wasn't even looking at Mary, he was looking at a songbird in the same general direction as Mary.
 * In the movie The Calcium Kid, Jimmy Connolly (Orlando Bloom) is a dim amateur boxer who becomes the focus of a BBC documentary. Not knowing that his whole life is being documented, he wakes up one morning and starts masturbating, not realizing that the scene is being filmed. The film crew interrupts him and Hilarity Ensues.
 * Angelas Ashes. It's set in Ireland, and there were four or five young boys as the main group of kids. They regularly went off to this rocky, hilly landscape and would jack off (next to each other, but apparently not "with" each other). Then, being Catholic, they'd have to confess their sin. It helped that the old priest was mostly deaf and didn't really pay attention to a word they said... until one day one of the boys slides into the booth all set to confess and finds a new and very alert priest there - the other one had died during the night.
 * A similar moment occurs when one boy charges his classmates to peep on his older sisters as they prepare for a bath. One of the boys gets a little overzealous, and ends up pulling the drainpipe he was clinging to off the wall, causing the rest of the boys to be caught in the act as well.
 * Iin Slackers there was a scene where a male character had to steal something from a female characters dorm while she wasn't there. After trying the door he was impatiently allowed in by the female character's (also female) roommate who was annoyed at having been interrupted masturbating. She continues to masturbate (quite enthusiastically) in the main room while he goes to the bedroom to find the whatever it was.

 * In Eternal Sunshine of the Spotless Mind, one of Joel's memories is getting caught masturbating.
 * Jim Carrey also gets caught in Ace Ventura: When Nature Calls.


 * Michael (Dustin Hoffman) in Tootsie gets quite literally caught with his pants down by Sandy. His reaction is classic:
 * In Going Berserk, John Candy's character is recounting a recurring dream to a psychiatrist - it's seen as a parody of "The Blue Lagoon", where his advances to the girl he's on an island with are constantly rebuffed (in direct contradiction to his narrative) - he goes off to another part of the island to be "alone with his thoughts" as he says, which means to furiously masturbate. He then looks up, and finds he's not alone - a cruise ship is passing by with everyone on board watching and laughing at him. As he ends the story, he's dismayed to find the psychiatrist laughing uproariously.
 * In Beavis and Butt-head Do America, Beavis (in his Cornholio persona) sees Mr. Anderson's camper, pulls out a picture of the woman he was sent to "do" and then goes into the camper. Later, Mr. Anderson is curious to find out why his camper is rocking, and investigates. Hilarity Ensues.

 * Happens to the teenage Bruce Wayne (the Michael Keaton version) in the parody "To The Batpole!" in the anthology Batman Unauthorized.

 * Similarly, this Youtube Poop involves Sonic the Hedgehog masturbating and ejaculating on Robotnik. Since Robotnik is Sonic's arch nemesis, Sonic is apparently pleased by this.
 * Alluded to in Pushing Daisies. Chuck and Ned share an apartment, but if they touch Chuck will die, so they wear jingle-bell slippers to alert each other when they're coming into a room. Chuck tries to convince Ned that she should move out:

Ned: That would never have happened if you were wearing your slippers.

(You'd think that since they can't touch, they might have resorted to mutual voyeurism as one of the only forms of sexual activity that would allow them to safely be in the same room, but Ned is a very self-conscious person.)"

"Judge Serkis: That's enough, Mr. Sex. Sacks!"

 * Happens again with !girlCurtis getting caught in the act in the most recent season
 * In The Inbetweeners one of the characters is volunteering at an old folks home, where he constantly wanks in empty rooms (which is quite in character for him). At one point he ends up looking for ANYTHING to do the deed to and finds a picture of a woman in a bikini, which is enough to get him going. As soon as he reaches the point of no return the woman in the picture (who was in the room the whole time) sees him and calmly says that she's seen it all before. Then a nurse comes in with a man, who shakes hands with him (only to realize that he has an unknown goo on his hand).

Having seen what is on the computer screen, the Doctor turns to him and says, scornfully, "Get a girlfriend!"
 * In the Stargate Atlantis episode "Grace Under Pressure," Rodney McKay is badly injured and hallucinates seeing his long-time crush, Samantha Carter. Even though he's well aware that she's just a figment of his imagination, he works with 'her' to try to help his situation. When 'Samantha' comes up with an idea that gives him much-needed extra time, he jumps up and hugs 'her'. He suddenly turns serious and moves in for an amorous kiss, but 'Samantha' spoils the mood by pointing out, "You do realize what you're doing here, right?" Possibly only a partial example, because the person who caught him was actually his own subconscious. (Rodney was a complicated guy.)


 * On the re-imagined Battlestar Galactica, Gaius Baltar is haunted by visions of his Cylon ex that nobody else can see. She frequently gets romantic with him.

She gets in trouble when the friend's mother walks in, and when she takes Sally back home her mother yells at her and threatens to cut her fingers off if she does it again - in public or in private.
