A character suddenly finds their breasts enlarged to often immense levels, via [[Applied Phlebotinum]], magic, science, or otherwise. Mostly happens to flat chested characters suffering from [[A-Cup Angst]], though women on the other side of the spectrum may have it happen as well. When played for the [[Fetish Fuel]] side, the actual growth tends to be as important as the final size of the breasts. It is also played for [[Gag Boobs|comedy]], but this still ends up providing [[Fan Service]]. An [[Overnight Age-Up]] for women usually guarantees this will happen.

An alternative is [[Fake Boobs]].

{{examples}}
== [[Advertising]] ==
* One banned Japanese commercial shows a woman drinking milk and her breasts growing.

== Anime and Manga ==
* ''[[UFO Princess Valkyrie]]'' has a scene in the second season after Valkyrie makes a cookie bigger with magic. Just after that Hydra makes a joke about making Akina's breasts bigger. Guess what happens.
** The series as a whole features Breast Expansion heavily. Every transformation sequence features prominently a scene of Valkyrie or Hydra inflating their breasts to [[Gag Boobs]] capacity as they turn into their adult forms.
* A rare non-human example happened in ''[[Mazinger Z]]''. In episode 32, [[Battle Couple|Kouji and Sayaka]] have to battle a flying [[Robeast|Mechanical Beast]] (Gelbros J3). Kouji thought replacing [[FemBot|Aphrodite A's]] [[Torpedo Tits]] for bigger missiles would help to defeat it. [[It Makes Sense in Context]].
* The second episode of ''[[Magical Shopping Arcade Abenobashi]]'' had Sasshi defeat the final boss by using a magic talisman that Arumi bought, which turned out to be used for breast expansion - the boss's chest swelled up so much it ''exploded''. Yikes.
** It should be noted that this was a giant monstrous skeleton in armor.
* The opening theme for the first few arcs of ''[[NEEDLESS]]'' shows Eve having breast expansion after she has her drink.
* A breast ''inflation'' spell has been used twice in ''[[Mahou Sensei Negima]]''. The results are always a hilarious fail:
** In one example, Asuna gets in an argument with some other girls over breast size. To help her along, Negi enhances Asuna's breasts by using a spell to make her swim-suit inflate like a balloon. At first Asuna happily belittles a [[Alpha Bitch|snooty blonde girl]] who was making fun of her, but then the spell backfires and she overinflates, causing the chest area of her suit to explode.
** In the other Anya and Nodoka attempt to inflate their breasts through sorcery, ends with them humiliating themselves in front of their classmates by overinflating and floating away like balloons.
** However, Makie manages to mildly inflate her chest and ''drain'' Yuuna's... [[All Just a Dream|in a dream sequence.]]
**  {{spoiler|At the end of the story, Nodoka's breasts have started to grow as a result of being in low gravity.}}
* The ''[[Eiken]]'' OVA actually has a subtle version of this trope. A running gag is when Densuke is able to hold Chiharu, he thinks to himself that Chiharu's breasts have grown larger than the last time he hugged her. Granted, Chiharu's breasts grew during the manga, but that was far more spread out, whereas the OVA occurred over the course of a few days!
* In one manga about a [[McNinja|wandering freelance doctor]], a young girl's [[A-Cup Angst|insecurity]] leads her to get a boob job. But the faulty implants are making her sick, leading [[Life or Limb Decision]]: the doctor tells her if she keeps the implants, she'll die, but if she gives them up she fears she'll be mocked again for being flat. In the end she refuses to have them removed, even though she knows the consequences.
* ''[[G Taste]]'' has a Breast Expansion scene where the girl's breasts burst out of her clothes.
* Hentai anime ''[[Angel Blade]]'' and its sequel features this heavily, as the titular (no pun intended) main character goes from an average size to well-endowed every time she transforms.
* ''[[Sailor Moon]]'' featured an odd variation of this. One of the monsters of the week shows up as a flat-chested girl in a swimsuit. She then produces two magical balls and swallows them, and instantly grows boobs of the same size. The action then freezes and a message comes up reading "PLEASE DO NOT TRY THIS AT HOME."
* In the newer ''[[Dirty Pair]]'' series, Dirty Pair Flash, Kei's transformation scene sometimes includes her breasts doubling in size and ripping through her shirt.
* ''[[School Days]]'': Episode 5. One of the girls uses an inflatable bikini inserts to give herself large breasts.
** That's also in the original game, and IIRC the girl who did that was the local flat chested girl Setsuna.
* Yuki the Ice Spirit from ''[[Master Of Mosquiton]]'' gets a transformation sequence where her breasts literally inflate like balloons when she turns from a [[Token Loli]] into a buxom hottie.
* In ''[[Puni Puni Poemy]]'', one episode sees some of the characters (including the [[Token Loli]]) imagine what they would do with the titular character's magic powers...two of them, including the [[Token Loli]], imagine them making their breasts larger.
* One doujinshi manga (don't ask, [[NSFW]]—loli ''everywhere'') features the loli girlfriend of some guy, who has her breasts surgically enlarged because she thinks it'll make her more appealing to him...but really, he only liked her ''because'' she looked flat-chested. So needless to say he's ''not'' impressed, yells at her, and throws her out. But she completely misreads this and assumed she's not ''big enough'' yet. At the end she's going [[Bigger Is Better|back for more.]]
** A similar doujinshin/hentai has a teenaged girl suffer a similar problem. [[A-Cup Angst|Insecure about her size]] and wanting to impress some breast-obsessed boys who fawn over ''bakunyuu'' (read: big titty) manga, she gets an [[Gag Boobs|enormous boob job]] to meet their standards. But instead they get [[squick]]ed by her huge chest and reject her advances. She assumes it was because her breasts are still too small, and tries going bigger, still longing for their approval. When they ''still'' reject her...she decides she [[Comically Missing the Point|needs to be even bigger.]]
** Aaaand...different comic, similar plot: two sisters, the older one [[A-Cup Angst|flat-chested and insecure]] the younger one [[Gag Boobs|comically oversized]] and [[Big Breasts, Big Deal|boastful about it]]. After being humiliated by her "little" sister, who is still growing, the older girl decides to have her breasts enlarged....
* Two bakunyuu mangas by the late Sakuraba Jouichirou heavily feature Breast Expansion:
** ''Great Breast Miyuki'' (a.k.a "Miyuki's Marvelous Melons") involves a shy teenaged girl who makes a deal with the Devil...or ''A'' Devil...to be more popular. The result is that now her breasts inflate to absurd sizes when she becomes aroused. But she manages to turn this into something fruitful, becoming a big-bust model in her part time. At one point she has a brief rivalry with a [[Gag Boobs]]-equipped model who, out of jealousy, makes a similar deal with "A" Devil to get bigger breasts...unfortunately, she starts growing out of control, humiliating herself trying to one-up Miyuki. Later Miyuki meets a boy from school she has a crush on, who tells her he loves her too and, trying to impress him, she forces her breasts to grow bigger than her whole body. She succeeds in rapidly gaining his love (and lust) but regrettably she can't handle the weight of being so top-heavy and, like the Mighty Endowed, [[Hoist by His Own Petard|she topples forward, unable to stand, and crushes him to death]].
** ''Hyper-Breast Girl Rikaku-chan'' is a quasi-parody of big breasted manga girls. The title character, Rikaku, is a teenaged seductress who is so comically buxom as to basically being deformed—her breasts are [[Gag Boobs|twice as big as her actual body]], measured in ''meters'' not inches. And she's still growing. Besides basically attacking men on the street with her breasts, forcing them to grow at will hoping to impress her suitors, Rikaku also gets easily frustrated when someone doesn't acknowledge how huge she is. At one point her boss at her job guesstimates her breast size at "two meters", and she angrily puffs up her chest and chastises him, telling him she hasn't been so "small" since she was a preteen...cue picture of Rikaku as a prepubescent girl with breasts bigger than her whole upper body. Rikaku is something of a parody though, [[Refuge in Audacity|being so big she's basically a joke]], bragging about her size and inflating herself like a mating bird looking for a spouse when she sees a suitable man.
* ''Sakuraba Jouichirou'' also did a series of Breast Expansion short stories in manga form (floating around the net). One including a boy getting laid for the first time by a woman he meets with breasts '''even bigger than Rikaku'''. Like by an order of magnitude. It's kind of implied she smothers him by mistake at the end. Another involved a girl with huge breasts trying to peel her bau away from her [[Hot Mom]] who has outright [[Gag Boobs]].
* A hentai manga (one of many...) involves B.E. to some degree. A guy goes to the plastic surgeon to have his [[Bigger Is Better in Bed|"self" lengthened]], and meets a girl he knew as a kid...who he barely recognizes because now she has [[Gag Boobs|basketball-sized breast implants]]. She's, needless to say, happy to get a second chance at him, but then her superior shows up...who ''also'' has implants, only about ''three times as big'', and humiliates her in front of him by calling her "puny" and "little". This leads to a predictable competition.
* In ''[[Pokémon (anime)|Pokémon]]'''s episode "Beauty and the Beach", [[Villainous Crossdresser|James]] of Team Rocket wears a breast-expanding bikini top and taunts Misty about his greater size. When the episode was finally aired in the West, the scenes featuring this were cut.
** Inverted with May - her breasts (possibly due to being [[Off-Model]]) go from the size of a grown woman's to mosquito bites by the D/P arc.
* When three of the angels in ''[[Wedding Peach]]'' [[Grand Theft Me|switch bodies with magical cats]], the girls turn into [[Catgirl|Cat Girls]], and their breasts grow. Their breasts shrink back after the girls return to normal.
* An episode of ''[[Tokyo Mew Mew]]'' involved the girls fighting a pair of birds who inflated their breasts to use as weapons. Specifically they use them as balloons, bounce the main heroine around till she's dizzy, and chasing the boys around.
* In ''[[Queen's Blade]]'', the character Melona (ironic name) basically has the power of breast expansion: she can not only make her breasts larger, but has [[Gag Boobs]] already and uses her rapid breast growth as a weapon. Her introduction scene has her slightly inflate her breasts for simple one-upmanship, and she likes to boast about her huge boobs. [[Hoist by His Own Petard|Ironically]] Melona's breasts become her downfall, when she fights an enemy who can overcome her attacks, Melona overcompensates and inflates her breasts too much, causing them to '''explode''', killing her. Of course, lucky for her fans, later episodes show that she got better.
* Seras Victoria from ''[[Hellsing]]'' starts at a fairly average cup size and then swells enormously after she becomes a vampire. Apparently, vampirism comes with some serious breast expansion side effects.
* ''[[Magical Girl Lyrical Nanoha]] [[Spin Offspring|ViVid]]''. [[Seinen]] series with a [[Older Alter Ego]] [[Transformation Sequence]]. Naturally, one of the panels during said sequence focused on the character's breasts that had grown to large proportions.
* The [[Gag Dub]] of ''[[Ghost Stories]]'' [[Subverted Trope|subverts this trope]]. Satsuki tries to get a wish granting ghost to give her "huge boobs", but does it wrong so it doesn't happen.
* In the manga ''[[Manyu Hikencho]]'', the story is set in a fictional fantasy world where [[Buxom Is Better|breast size determines a woman's worth and position in society]]: small breasted women are outcasts and well endowed women are showered with wealth and power. In effect, [[Buxom Is Better]] taken literally. The main character is a "thief" who [[Break the Haughty|steals breast size from busty girls]] and gives advice to flat chested girls on how to increase their bust size, in someways being a "robin hood" of breasts.
* In ''[[Cyber Team in Akihabara]]'', [[Alpha Bitch|Kamome]] one of the five [[Magical Girl]]s is ashamed of being flat. So she uses a pump to inflate her chest in the beach episode, and handily attracts a gaggle of boys. Also, all of the girls get pretty damn big when they transform.
* Episode nine of ''[[Kamen no Maid Guy]]'' features an entire restaurant which [[Buxom Is Better|hires only busty girls]] so the waitresses can use their assets to [[Distracted by the Sexy|distract the predominantly male customer base]] from [[Lethal Chef|noticing the horrible food]]. Nekka, the main heroine, is sent in to "investigate" by her flat-chested friends because they feel their restaurant is being "outgunned". It turns out that all the waitresses have had boob jobs, while the manager is a flat chested girl who's been padding (to a ridiculous extent) the whole time.
* In the Transformation-tastic episode of ''[[Onegai My Melody]]'', a skinny underdeveloped girl uses (kinda') dark magic to steal other girls' physical features. Aside from stealing one girl's face, and a leggy [[Tomboy|tomboy's]] legs, she also steals a busty blonde's chest size, and some hips. By the time she's done, no one who knew her before even recognized her. Her plan falls apart when she gets greedy, causing the spell to go haywire when she tries to take on too many enhancements at once. This is episode 24 season 1, in case you are "interested".
* ''[[Grenadier]]'' had one episode where the enormously well-endowed main character's flat-chested cohort, Mikan, puts on a pair of big inflatable breasts, ostensibly to [[Ho Yay|show off for her friend]] it appears.
* ''[[Jungle de Ikou!]]'s'' entire plot centers on a flat chested girl with breast-obsessed friends, who becomes the tall, tanned, massively buxom woman she always wanted to be thanks to magic. Unfortunately it also unleashes a demon bent on destroying mankind... fortunately he's more than happy to [[Distracted by the Sexy|just stare at her boobs]].
* ''[[Change 123]]'' - When the main character's [[Split Personality|split personalities]] manifest, her appearance changes due to subtle differences in the placement and internal balance of her muscles necessary for their different [[Stance System|combat specialties]] (attack power, speed, and defense). The usual sign that the [[Adult Child]] grappling specialist has come out is that her bra snaps as her boobs "grow" too big for it. [[Hand Wave|Presumably]] this is the result of her pectoral muscles pushing them farther out than usual.
* One hentai manga, the title of which is spoilerized for being [[NSFW]] ({{spoiler|''Tiny Boobs Giant Tits History'}}), features Breast Expansion as a central plot point. A flat teenage girl is repeatedly hit there and mocked by her brother. His constant slappings cause a sensation which causes her breasts to grow. Her sudden increase in bust size causes her to become rather arrogant, boasting about the size and weight of her new breasts and teasing her brother about her new prospects as a glamor model. Somehow, this also causes her to [[Brother-Sister Incest|have sex with her brother]]... for some ([[Fetish Fuel|hot]]) reason. Throughout she makes fun of her brother's incredibly [[Teeny Weenie|small penis]] ([[Compensating for Something|which sheds light on why he mocked her earlier]]) but the ending implies he'll soon be having some [[Gag Penis|growth]] of his own. A panel where she grabs her new breasts and presses them against her brother's face, grinning evilly, has been [[Memetic Mutation|mutated]] into a meme on "Teh Internets".
* Chapter three of the manga series ''[[Asklepios]]'' has the protagonists trying to convince a village girl to let them operate to remove a tumor on her ovaries that's caused a huge increase of her bust size, but at the same time is killing her. She initially refuses because she thinks her love interest likes big breasts, but eventually accepts the surgery when said love interest says he cares about ''her'' and not her bust. After the surgery is over, he even says she looks better flat-chested.
* [[Mahoromatic]]: Mahoro is fairly insecure about her relatively small bust. She's, therefore, understandably upset in the dream sequence episode where her breast enhancement device works on Minawa, [[Gag Boobs|Shikijo]], and even the male Suguru, but not on her.
* A subversion occurs in ''[[Slayers]]'' when flat chested [[Person of Mass Destruction|Lina Inverse]] was told of a fountain that makes things grow as a reward for a quest. It turns out {{spoiler|the magic spring she was told of would have made her old.}}
* [[Subverted Trope|Subversion:]] Once, [[Cheerful Child|Makoto]] of ''[[Hell Teacher Nube]]'' stole a bag of magical dust from a benevolent [[Youkai]]—dust with the power to make anything grow. Among the many scenes of carnage (such as extending Nube's prodigious eyebrows down to his knees, or causing Noriko's cute crown of flowers to completely engulf her,) [[The Tease|Miki]] sprinkled this dust on Kyoko's chest. It inflated... inflated... '''''[[Bold Inflation|INFLATED]]'''''... and just when Miki was horrified and outraged at being surpassed, and the entire classroom stared, two actual ''melons'' dropped out of Kyoko's blouse, as the dust had only affected a couple of seeds that had dropped in there during lunch.
* One series of manga circulating around the web (dubbed the "Fraction" series) is made of this trope. It includes a story about a teen girl whose breasts are so huge she gets teased for it who meets a porn star with even bigger breasts who teaches her to be proud of herself. Interestingly the porn star woman admits that, as a teenager, she was a flat chested girl who wanted to be big so badly she got ''enormous'' breast implants to achieve this.
** Two other "Fraction" series manga include a short about a girl who takes hormone pills (given to her by the ghost of her dead friend, [[Crazy Awesome|naturally]]) and gains breasts bigger than her torso; and a young woman who is infected by an alien parasite that makes her breasts go from completely flat to around an F-cup in seconds, but another alien shows up (this one a buxom blonde already equipped with huge tits) who wants the breast-enhancing alien for herself, [[Bigger Is Better|for obvious reasons]]. Naturally the human girl is reluctant about giving up such a creature.
* In the hentai manga ''Injection Girl'', a flat preteen girl who despises being flat-chested goes to a [[Back-Alley Doctor|shady plastic surgeon]] and undergoes breast augmentation to increase her breast size (ostensibly because she thinks she will be a famous idol singer if she has bigger breasts). Naturally, this backfires terrifically, as her boobs grow out of control and the doctor makes her his S&M slave. Kinda' dark yeah?
** Basically the same plot, but in a different hentai, titled ''[[Before After]]'': a flat-chested high schooler goes to a black market plastic surgeon to have her breasts enhanced. After the operation she soon realizes her breast implants are continuously growing. Turns out they are remote controlled, and the doctor (a woman doctor this time) makes her a sex slave by making her breasts too big for her to move under her own power.
* One ''[[Tenchi Muyo!]]'' doujinshi involves Washu giving the other girls in Tenchi's harem enormous breasts for some reason, making Ryoko incredibly jealous, especially when [[Alpha Bitch|Ayeka]] shows up in the hot tub with volley ball-sized breasts and openly mocks Ryoko. She tries to top them by making her own breasts larger in a similar fashion, but ends up making her breasts so huge she can't move at all. Ayeka doesn't really get what she wanted either...she thinks Tenchi will enjoy her "newly enhanced" body more, but she never gets to find out because Mihoshi and Kiyone go to town on her, [[Unusual Euphemism|if you catch my drift]].
** From the actual show itself, one instance involved Washu, again for some [[Fetish Fuel|hot]] reason, talking Sammi into taking a drug that caused her to age into a teenager... including her breasts, which swell up about six cup sizes.
* The manga series ''[[Blue Eyes]]'' features a kind of, believe it or not, more ''realistic'' breast expansion sequence. No seriously. Indeed it's vaguely [[Deconstruction|Deconstructive]] about the whole concept. One of the characters, Claire, started out flat-chested as a teen but then she started developing very rapidly. At first she was happy about it and soon her breasts grow bigger than even her mother, who was already ''cartoonishly big''. But then they started growing out of control and eventually, by the time she's in her late-teens, her breasts are larger than her entire torso and she is so embarrassed she becomes a recluse.
** On a related note, one of said girls that gets introduced later on, Meg, is going through puberty herself, and it's implied as Tatsuya has sex with her, that her breasts are getting bigger every time he sees her. [[Author Appeal|It's quite clear what the artist Tohru Nishimaki likes, and that's big breasts]].
* A story from the manga ''[[Franken Fran]]'' featured the titular character (an insane [[Body Horror]] plastic surgeon-cum-frankenstein monster) passing out free cosmetic surgery to some kids at a school. Besides odd instances like a couple who wanted to be stitched together, one girl apparently asked for [[Gag Boobs|breast implants twice as big as her torso!]]. The terms "overcompensation" and "something to prove" comes to mind. Hilariously enough, she calls out the other students for the procedures they had done on them, saying that they "lack restraint" and the kicker being that compared to most of the students [[Squick|she's right.]]
* In one of the happier Breast Expansion hentai manga, titled ''Blimps'', a girl and her boyfriend discuss her breast size (or lack thereof), and she decides she must get bigger breasts to measure up. So we cut to a few months later, and now she has [[Gag Boobs|enormous implants]] bigger than her head. In an unexpected, but sweet, happy ending her boyfriend loves it and after the pre-requisite graphic sex scenes they decide to get married and start a family.
* A similarly happy-ending-possessed Breast Expansion hentai short-story involved a girl whose breasts inflated cartoonishly whenever she was sexually aroused...who has to tutor a boy she's in love with. About a minute into the meeting, her chest becomes home to twin beach balls. Needless to say, [[Bigger Is Better|he's extremely impressed]], and graphic sex follows. It too ends with them forming a really, ''really'' kinky but otherwise loving relationship.
* In the hentai ova ''[[Taimanin Asagi]]'', Sakura the protagonist's younger sister is captured while trying to rescue the protagonist. She is then repeatedly raped throughout most the series. The first act being getting her breasts medically expanded to huge proportions. Fortunately, later on [[Earn Your Happy Ending|she gets better]]
* In the hentai, ''[[Bondage Queen Kate]]'', the title character (already well-endowed) is sent to infiltrate an evil organization that kidnaps and sells young girls into sexual slavery. It is outright stated that the girls are given breast augmentation to make them more "useful".
* In ''[[Black Butler]]'', episode 23, a slightly-endowed {{spoiler|Angela}} tries to tempt {{spoiler|Sebastian}} by showing off her assets, and they actually look bigger than in previous episodes. Possibly justified by the fact that {{spoiler|she's not human anyway.}}
* In a chapter of ''[[To Love Ru Darkness]]'', Lala invents a machine that does this. Though all it really did was transfer the size of one's breasts to another for a brief period of time.
** In the original ''[[To LOVE-Ru]]'', one chapter has [[Voluntary Shapeshifting|Golden Darkness]] use her [http://www.mangafox.com/manga/to_love_ru/v12/c100/16.html shapeshifting] [http://www.mangafox.com/manga/to_love_ru/v12/c100/17.html powers] for this purpose.
* ''[[Magical Canan]]'''s protagonist Chihaya has a mild issue on her small bust. When she [[Transformation Sequence|transforms]] into her alter ego, [[Magical Girl]] Carmine, [[Fetish Fuel|the camera intently zooms on how she grows her breasts and butt's sizes.]] They shrink back when she turns to normal.
* In ''[[Gou Dere Bishoujo Nagihara Sora]]'' The flat-chested girl Tenka Morooka gets this unwillingly at the end of chapter 3,at first she don't want "them" because they are [[Gag Boobs|"heavy"]] but in the end she decides to keep them.
* In the manga ''[[Okitsune-sama de Chu]]'', a cow demon possesses a girl and causes her breasts to grow from flat to about the size of her head. They eventually grow to almost fill a room. Even when the demon is removed, [[Fan Service|she keeps some of the expansion]]. It happens a few more times throughout the series.
* Early on in ''[[Benten-sama ni wa Iwanaide]]'', this trope is magically invoked for the sake of revenge. The subject's bust begins to grow slowly and continuously over the course of several chapters, during which she is convinced to take part in a play of some sort wearing a very tight-fitting costume. The result is [[Clothing Damage|predictable]].

== Comic Books ==
* In ''[[Gen 13]]'', one of the side-effects of Caitlin's gen factor activating for the first time includes her cleavage expanding into CLEAVAGE.
* Outgunning even ''[[Power Girl]]'' effortlessly by a factor of HUGE is the short-running (and deliberately-comical) superheroine ''Mammary Woman'', who appeared in the now-defunct British humour comic UT. Initially a parody of ''[[Spider-Man]]'', the heroine was a put-upon nerdy schoolgirl with a very flat chest whose life changed forever when, on a visit to an underwear factory, she was bitten by a radioactive bra-strap. Later that night, the inevitable ''[[Fetish Fuel]]''-esque sequence occurs, as in the space of three frames her assets swell from bee-stings, to basketball-sized (bursting her school blouse open in the process), to about the size of three metres across and a triple-Z cup...EACH. She decides to use her superhuman boobs for the power of good, and so becomes the World's bustiest superheroine, Mammary Woman. In one later episode, she even expands them even further in a matter of seconds to about the size of a military hovercraft each, in order to buffer a crashing train and save its crew and passengers...
* One of the first foes faced by ''[[Young Justice (comics)|Young Justice]]'' was the Mighty Endowed, an archaeologist named Nina Dowd ("N. Dowd") who was transformed into a top-heavy feline figure too well endowed to support her own weight. In a twist, despite her being fully clothed, her new assets are never clearly seen.
* The comic ''[[Three Little Kitties|3 Little Kitties]]'', by Jim Balent, features the villainous Latex Red who takes breast augmentation to a new extreme...her implants are filled with explosives, so if you kill her you blow up too.
* Much like the TV series that it spun off (see Western Animation below) the ''[[W.I.T.C.H.|WITCH]]'' comic features this. Since the characters are mainly teenaged girls breast size features heavily in their major concerns. Will, the team leader, is a flat chested girl who uses her enhanced [[Older Alter Ego|Magical Girl form]] to offset her lack of size, while tomgirl Irma is already the biggest, but [[Buxom Is Better|tries to make herself bigger anyway out of pure vanity]].
* In ''Chaos Campus: Sorority Girls vs Zombies'' (yes that's the title), one character, Jamie, is a goth-ish poser who complains about feminist issues and "society's obsession with beauty"...who also has [[Gag Boobs|volley ball-sized breast implants]]. She's very short, you see, and so she got increasingly larger and larger implants to compensate, or in her case, [[Bigger Is Better|overcompensate]], for not being "big" anywhere else. Needless to say, her two friends, [[Gag Boobs|Brittany]] and [[Tall, Dark and Bishoujo|Paige]] see straight through her.
* In ''[[Little Ego]]'', Ego has a dream in which a cream causes her breasts to grow in size. She is initially delighted until she realizes that they are continuing to grow. Soon she is having trouble fitting through doorways and none of her clothes fit anymore.
* While originally portrayed as flat-chested, ''[[The Authority]]'' team member Shen Li-Min, aka "Swift", eventually paid for some very expensive breast implants and likes to boast about it. [[Deconstruction|Given the nature of the series]] this is likely making fun of other well-endowed comic heroines.
* In the parody comic ''Babewatch'', all the female characters have unusually large breasts but one of the characters has inflatable breast implants she can use as a life preserver.
* Oddly enough though many comic book females are possessed of the [[Most Common Superpower]], several are also acknowledged to have had their breasts surgically augmented. Among them Outlaw (from ''[[Deadpool]]''), Emma Frost (from ''[[X-Men (Comic Book)|X-Men]]''), and Cat Grant (from ''[[Superman]]''). Jessica Drew is a maybe...depending on how you interpret [http://politedissent.com/images/feb06/newavengers_14.jpg this]
** The writer for that comic in which that panel took place outright said it when comparing [[Spider-Woman]] to [[Wonder Woman]] "Spider-Woman has better hair, better costume, '''Frank Cho implants''' and a fucked up origin"
** As it happened, {{spoiler|that turned out to be the exact scene where Drew was replaced by Skrull Queen Veranke.}}
* Casey from ''[[Strangers in Paradise]]'' gets breast implants. Twice.
* Mimi Masters in Fred Perry's ''[[Ninja High School]]'' story "Minor Adjustments", waking up to find that (with a little help from her equally sorcerous sister) she's magically sprouted medicine-ball-sized sweater-stretchers on her previously flat chest overnight.
* In Jules Feiffer's ''Passionella'', when Ella the chimney sweep transforms into Passionella the "beautiful glamorous movie star," one change that sticks out is that, while the former shows no perceptible bosom in her shapeless shift, the latter's breasts extend twice as far as her nose.

== Fan Works ==
* Done very, very squickily in ''[[Celebrian]]'', the legendary [[The Lord of the Rings]] badfic.
* Shows up in a slightly more disturbing instance in a ''[[Warhammer 40,000]]'' fanfic about a Farseer corrupted by Slaanesh.

== Film ==
* ''[[Back to The Future|Back To The Future II]]'', Lorraine's implants- "You made me get these...things!" Marty is naturally [[squick]]ed.
* Believe it or not, the climax of the 60s British comedy film ''The Bliss of Mrs. Blossom'' hangs on a character sabotaging a demonstration of a new kind of inflatable bra causing the bras to inflate out of control.
* In the B horror movie ''Bolt Neck'', one character is a tremendously [[A-Cup Angst|insecure]] teen girl. She disappears after the monster, a Frankenstein ripoff, shows up and everyone thinks she was killed...turns out she left to get illegal breast implants overseas. At the end she displays her newly inflated chest to the whole school, [[Bigger Is Better|with just the results she hoped for]].
* ''[[Bruce Almighty]]'' tried this on his girlfriend almost as soon as he got the powers of [[God]], despite the fact that the girlfriend was played by [[Jennifer Aniston]] (in real life a 36C, according to those who claim to know).
** The end result was as expected, plus a few [[Freudian Slip]]s.
* The end of ''[[Dude, Where's My Car?]]'' after the two leads give the alien necklaces to their girlfriends.
* ''[[Woody Allen|Everything You Wanted To Know About Sex]]''.<ref>''But Were Afraid To Ask''</ref> John Carradine plays a [[Mad Scientist]] of the Masters & Johnson's variety. One of his subjects is being fed silicone into her chest 24 hours a day. "She ''used'' to be flat chested, now look at her!" When the lab explodes, a 50 foot breast starts terrorizing the countryside.
* ''Faust: Love of the Damned'' has a scene that from Breast Expansion right into goes into [[Body Horror]] without any warning.
* In one of the ''[[Flesh Gordon]]'' spoof/softcore porn movies, a woman goes to a mad scientist to get a boob job, but he botches the job big time and, well...lets just say her ego wasn't the only thing that deflated.
* In ''[[Jane Austens Mafia|Jane Austen's Mafia!]]'' Vincenzo makes a wish under a falling star in one of the flashback scenes. His new girl friend's breasts expand (apparently without her noticing).
* ''[[Killer Klowns From Outer Space]]'': Near the end of the film are two female [[Monster Clown|Klowns]] whose breasts blow up just like balloons.
* In ''[[My Super Ex-Girlfriend]]'', the flashback scene where Jenny gets her powers makes it unmistakably clear that they include the [[Most Common Superpower]].
* In [[Howard Stern]]'s ''Private Parts'', Howard is at an airport and sees a hot woman walking by; he imagines her in only a bra, and then imagines her breasts getting larger.
* ''[[Repossessed]]'': The gym scene has a girl using exercise machine. With every rep her breasts blow up just like a balloon. Later {{spoiler|a pop is heard off camera.}}
* In ''[[Terminator]] 3'', the T-X increased her breast size at one point to [[Distracted by the Sexy|distract someone]].
* In the Asian (Chinese?) comedy ''Twinkle Twinkle Lucky Star'', a man becomes able to grant wishes, hence the name. One instance includes a woman who wishes for enormous breasts, but he decides to make her breasts so huge she becomes unable to stand, a la the Mighty Endowed.
* In ''When Evil Calls'', one death scene features a nerdy girl who gets inflated from flat to [[Gag Boobs|absurdly huge]] in a few seconds, which she looks rather happy (if shocked) about...till her chest ''literally explodes'' a few seconds later.
** A similar situation occurs in the movie ''[[Leprechaun]] 3'', where a woman wishes for a new, busty body on one of the titular imp's gold coins. But instead her breasts (and hips) grow out of control until they pop.
*** Similarly, in the horror film ''Corpses'' the evil force causing the ruckus in the film causes one of the female character's boobs to swell up till she explodes.
* In the ''[[Are You Being Served?]]'' movie, Grace Brothers have an expanding bra on sale (in case the wearer comes across a rock star), which [[Distracted by the Sexy|comes in handy]] when one of the characters is attacked by a randy terrorist, only to be startled by the sight of their 'breasts' expanding rapidly.


== Literature ==
* In the ''[[Gossip Girl]]'' prequel, ''It Had To Be You'', one of the girls becomes insecure that her breasts aren't growing, tries to enlarge her chest artificially using hormone pills. It works at first, but soon backfires spectacularly, as she keeps getting bigger and bigger and eventually [[Gag Boobs|gets ''so big'' she becomes a laughingstock]].
* A girl in ''[[The Clique]]'' series has a similar problem: Alicia develops ''way'' more rapidly than anyone expected...''allegedly'' naturally, [[Squick|but it's implied otherwise]]. She's surprised and embarrassed when she gets teased for her [[Gag Boobs|overinflated look]] by the other girls. [[Male Gaze|Guys however are way more impressed.]]
** It's actually an open secret that Alicia has implants and was forced to do so by her family, explaining why she's so insecure.
** Alicia's cousin, Nina, also has gigantic breast implants. Apparently both were forced to do this by their family to make them more appealing to older men. 
** Massie also has implants, explicitly mentioning them, but if she was also forced to by her parents or simply chose to get them out of vanity (probably the latter...) is never touched on.
* In "Savage Breasts", part of an anthology called ''Smart Dragons, Foolish Elves'', a woman gets a mysterious exerciser to make her bosom larger...but her enlarged breasts have a mind of their own.
* In "Dork Diaries", a rather humorous parody of ''[[Diary of a Wimpy Kid]]'', the central heroine punctuates her stories with drawings to explain the narrative. One of which is her fantasy of what she wishes she looked like...complete with larger breasts and an arrow pointing them out specifically, along with other cosmetic enhancements (though, unlike many characters here, they were simply very large instead of comically huge).
* In ''Fatal Beauty'' by horror novelist William Schoell, a corporate executive who's unhappy with her bust size uses her company's new miracle cosmetic product to increase their size. Unfortunately, the product is {{spoiler|made from the secretions of psychic genetically engineered monsters, so it causes horrible problems to all the test subjects. In her case, the tits grow enormously large and develop a mind of their own, turning homicidal and prehensile, and her best friend is forced to kill her to save herself and others.}}
* The title character of Lucy Taylor's short story "The Flesh Artist" is Cyrus Sweet, a sociopathic plastic surgeon who convinces his lovers to let him "improve" them. Evelyn, the small-busted sculptor who grudgingly agrees to go under his knife, receives a gargantuan pair of mongers. She dumps him immediately. Sadly, her problems have just begun. Years pass, and Sweet pines for "Tits" (his charming nickname for Evelyn). He looks her up, gets an invite to her house, and makes several awful discoveries, all related to the leaky sillicone he planted in her chest... and the terrible yet apt revenge she takes on him for doing it.
** This is actually similar to an online Breast Expansion short story, about a millionaire who becomes obsessed with a porn star's breast implants and coaxes another girl into getting dangerously oversized implants herself. Oh and the porn star, named "Mountain Tops", is mentioned in the epilogue in a passing, saying her breast implants "exploded" not long after...

== Live Action TV ==
* In ''[[Charmed]]'' episode ''Hell Hath No Fury'', Paige's breasts expand due to using magic for personal gain.
* ''[[The Collector (TV series)|The Collector]]'': In the third episode of the first season, a svelte supermodel rejoices when she finds her breasts swelling to massive size, but expresses grim dismay when the same thing happens to her ass.
* ''[[Attack of the Show!]]'' has a spoof of home exercise equipment and breast enlargement remedies called "EasyCurves".
* One of the first [[Imagine Spot]]s in ''[[Ally McBeal]]'' is of Ally's breasts growing until they snapped the bra straps.
* An episode of ''[[Popular]]'' had one girl trying to make herself look larger with an overinflated pump-up bra...with LOL-worthy [[Epic Fail]] results.
* One episode of ''[[Everwood]]'' featured a cheerleader who had her breasts surgically enlarged to make herself more popular but she soon suffers from complications from the operation. The main character (a doctor) says they have to go, but she's so desperate to look bigger she initially refuses, thinking she'd be humiliated.
* An episode of ''[[1000 Ways to Die]]'' included the story "Titty-Titty Bang Bang", which featured a woman whose botched boob job started expanding out of control, eventually exploding and killed her. (Note: said story was busted on ''[[MythBusters]]'', but then ''1000 Ways To Die'' doesn't bother with trivial things like credibility.)
** Also doubles as a jaw dropping [[Body Horror]].
* A late nineties cop drama, ''[[Pacific Blue]]'', featured an episode where teen girls were dying because they were having silicone injected into their breasts to make them bigger, with the help of a [[Back-Alley Doctor|disgraced former plastic surgeon]]. They were financing it by stealing cars. [[Truth in Television]]: in the early days of plastic surgery, this method of breast augmentation was somewhat common, and obviously quite deadly, yet [[Buxom Is Better|it didn't stop anyone from trying]]. Yes it was ''that'' important to them!
* Subverted in ''[[House (TV series)|House]]'': House suggests breast enlargement as a convenient explanation for the scars from a diagnostic surgery when the patient (an Air Force pilot who wants to become an astronaut) insists that the team do nothing that would make NASA's doctors suspect she had health problems. When asked why not breast ''reduction'', he points out that she'd be an unlikely candidate.
* ''[[That's My Bush!]]'': Bush's [[Dumb Blonde]] secretary tries to increase her intelligence by buying memory pills, but she gets mammary pills instead. ''Flight Of The Valkyries'' plays during her ultimate bust-out, which also saves her and her coworkers by breaking her free of her ropes.
* In ''[[Will and Grace]]'' when an old crush of Grace's with a fixation on large breasts gets in contact with her she wears a water-filled bra to inflate her breasts with predictable results. When the guy turns out to be a jerk it gives her a unique way to wreak revenge on him however.
* ''[[Scrubs]]'' has this in the episode [[A Day in the Limelight|Their Story]], in which [[Anything That Moves|The Todd]] had become a plastic surgeon, and convince [[Black Best Friend|Turk]] to let him perform this surgery on a 16 year old. In the end, by introducing him [[An Aesop|to the girl who explained why she wanted it]] in the first place.

== Music ==
* David Brody's ''[[Britney Spears|Make My Boobies One More Size]]''.
* [http://www.youtube.com/watch?v=JedkJVP-TM4 This] homemade music video, judging by the lyrics and images, implies a girl gets breast implants to show off at a beach but dies as a result...somehow.
** The point of the video could also be that since implants are so artificial, they literally lasted longer than she did.
* ''I Must Increase My Bust'' by [[Lords of Acid]].


== Radio ==
* The ''[[Firesign Theatre]]'': Booby Chew.


== Toys ==
* The "Growing Up Skipper" Barbie doll. [[wikipedia:Skipper (Barbie)#Modern .281973-2010.29|See Wikipedia]].
* While not "real", exactly, one issue of ''[[Cracked]]'' featured a satirical ad for 'Breast Implant Barbie'--a Barbie doll who has had her breasts surgically augmented. Part of the joke was that she could "leak" and deflate, and would need to be pumped back up again.


== Video Games ==
* ''Pai Touch!'': Breast Expansion is the main point of the game.
* In the ''[[Touhou]]'' fanworks, BE is the dream of several of the [[A-Cup Angst|rather under-endowed]] girls, including Sakuya and Youmu. Numerous ways to achieve this end exist, from [[Mushroom Samba|suspicious mushrooms picked by Marisa]] to [[Mad Doctor|Eirin's]] shady drugs.
* In ''[[Playboy]]: The Mansion'' you build up points that you can use to archive photos or on Cheats. One of these is to to instantly give all the women giant breast implants.
* ''[[Princess Maker]]'' and the Buxomize Pills. You have to use two of those to have a visual change on the avatar.
** A [[Let's Play]] of ''Princess Maker 2'' takes this [http://lparchive.org/Princess-Maker-2/Update%208/ straight into Nightmare Fuel territory].
* In the first ''[[Ratchet & Clank (video game)|Ratchet & Clank]]'' game, there is an [[Easter Egg]] of this. If you stand in front of the lady who starts the hoverboard race in Blackwater City and then do multiple flips, her breasts will slowly enlarge for every flip.
* In the game ''[[Tech Romancer]]'', one character named Polin appears to be a young girl who uses her [[Magical Girl|magical abilities]] to transform into a tall, buxom teenager. She actually gets into an argument with another character over who has bigger boobs.
* Actually part of the gameplay in ''[[Bunny Must Die]]''—Bunny can get a special [[Playboy Bunny]] costume that allows her to induce spontaneous Breast Expansion and return to her normal proportions. Getting enormous breasts [[Boobs of Steel|increases her attack and defense]], but reduces her speed and jumping ability.
* In ''[[The Spellcasting Series|Spellcasting 301]]'', one of the challenges is a wet t-shirt contest. One of the two things you need to do in order to win is to recruit a very flat chested girl and cast the UPPSSY (reverse condition) spell, which makes her improbably stacked.

== Web Comics ==
* While it has yet to occur in the main story, [http://extras.thewotch.com/index.php?date=2007-01-17 these two]{{broken link}} [http://extras.thewotch.com/index.php?date=2007-01-19 filler strips]{{broken link}} of ''[[The Wotch]]'' have this happen to Anne.
* The central theme of webcomics by Lightfoot.
** In the series ''Pulse'' the main character, Annie Chang, a former flat chested girl gets superpowers through a [[Freak Lab Accident]] and as side effects getting huge expanding lactating breasts, they keep growing throughout the series. At one point while fighting crime as a sidekick her partner makes up a story to the press that she's a robot and the breasts are actually missiles.
** ''Peeved'' deals with a [[The Woobie|down on luck main character]], named Eve. Things change when she finds and becomes the master of a [[Genie in a Bottle]]. As with most comedies involving genies [[Hilarity Ensues]] and through the course of the series she goes through breast expansion three time, ironically not once did she wish for bigger breasts
** There's also ''My Big Life''. The main character is a reporter who's writing a column about the trend of women getting giant breasts, she does this by getting gargantuan breasts herself and reporting on her experience for a full year. Fortunately, because the series takes place in the future, there's technology available to turn her crippling huge breasts to nothing more than an inconvenience .
** He also did a [[Final Fantasy]] fan comic called 'The Missing Materia Crisis' where Yuffie gets her hands on a materia that causes growth and abuses to hell making every woman in her line of sight as big as possible, all the while Materia from all over the world is mysteriously vanishing. By the end of the comic nearly every woman effected has breasts that weigh twice as much as the rest of them....at minimum.
*** He has recently canceled all his ongoing series which focus on breast expansion so he can focus on more serious works. He has been releasing a reboot of Pulse which while still having BE as part of the story is no where near as blatant at the previous incarnation.
* ''[[Calamities Of Nature]]'' features a series of comics in which a character invents [https://web.archive.org/web/20130523032758/http://www.calamitiesofnature.com/archive/?c=278 helium breast implants] so that women can have larger breasts and lose weight at the same time.
* ''[[The Magnificent Milkmaid]]'', and it's spin-offs, involve non-stop Breast Expansion and [[Fetish Fuel|transformation fetishes]]. The central character, a teen girl, is a [[Magical Girl]] who can turn into a maid-like superheroine with breasts as big as her torso and has energetic lactation. Her enemies include a jealous girl who underwent a procedure to have "grossly oversized" breasts instead of a flat chest, a werewolf girl whose breasts swell about twelve cup-sizes when she transforms, a prudish girl who turns into a busty lesbian vampire, a shy young woman who turns into a busty muscle girl, and a guy called (no joke) the Towering Erection... guess why.
* In one storyline from ''[[Sore Thumbs]]'', normally flat-chested Harmony gets breast implants when the busty heroine of the series disappears and she feels she has to pick up the slack. She later had them removed because her friend returned...and because she initially had trouble standing upright under the weight.
* From the creators of Magnificent Milk Maid comes ''The Adventures of Chi-Chi Chan'' about a child star who's career is cut short when puberty hits.....her breasts. Tired of getting roles in obscure hentai, she moves to America to find new stardom.
* In a milder example, Chloe of ''[[Eerie Cuties]]'' demonstrated that [[Horny Devil|Succubus]] puberty was rather abrupt at times. Unfortunately, Chloe - who had been suffering from [[A-Cup Angst]] - doesn't seem to think she's better off now. 
* The web comic ''[[Supermegatopia]]'' (a furry world with many superbeings) has their BE mascot in the subtly-named ''Buxom Gal''. Her origin involves a breast expansion experiment carried out by aliens. Afterwards, she is left with standard superpowers (superstrength, flight, ability to fire power bolts), but discovers that - if she does not use her powers - her breasts (which "store" the energy for these powers) expand to incredible size, with incredible speed.
* Newly minted webcomic ''[[Love Me Nice]]'', about the crass [[Animated Actors]] of a hit TV show, has one character, Carolina, get breast implants because she looks like a cutesy little Rainbow Brite-ish doll and wanted to be taken seriously by men. [[Anvilicious|Predictably]], [[Hoist by His Own Petard|the opposite occurs]].
* ''[[Megatokyo]]'' had a slight case of this in [http://megatokyo.com/strip/880 this strip.]
* [https://web.archive.org/web/20130719025118/http://www.drunkduck.com/The_KAMics/5055109/ This comic] of ''[[The KAMics]]''
* Strangely, ''[[El Goonish Shive]]'' doesn't use this quite as much as one would expect - the closest example being the infamous Female Variant Five transformation beam, which increases hair length and bust size among other effects. Also outright subverted in an [[Omake]] comic, where Ellen attempts to invoke her "Wonder Twin Powers"...and fails to increase her bust.
* As a Christmas wish for Brendan in ''[[Pokémon-X]]'', the author does this to May, leading to what may be the first pixelated case of this.
* A defunct webcomic by an artist named "Jae", titled simply [https://web.archive.org/web/20100308121704/http://process-productions.com/~panikjae/amy.html ''Amy''], focuses on the eponymous young woman who undergoes a breast augmentation procedure because, as she puts it, "I'm 18 years old, and FLAT CHESTED!" The doctor is so concerned with [[Distracted by the Sexy|looking at her ass]] that he botches the thing, and she's left with breasts rapidly increasing in size...unable to get back in contact with him to fix her new knockers, she has to face the grim outlook of breasts twice as big as her head and ''still growing''.
* Breast Expansion is [http://www.bloomingfaeries.com/?p=1294 one of the powers] Prince Albert has over his [[Brother-Sister Incest|bratty older sister]] in ''[[Blooming Faeries]]''.
* [https://web.archive.org/web/20130207043550/http://blondemarvel.com/2011/02/03/expando/ This page] of ''[[The Blonde Marvel]]'' puts a new twist on the trope.
* Played with with [http://oglaf.com/freshhorses/ this] very NSFW two-strip story in ''[[Oglaf]]'' along with a few other not-so-popular fetishes such as lactation and "squirting".
* in ''[[The Whiteboard]]'', a pot of [[Klatchian Coffee]] grants the women who drink it a temporary increase of their bust size.

== [[Web Original]] ==
* In the "Amplified Bible" episode of the ''[http://www.illwillpress.com/vault.html Foamy the Squirrel]'' animated web series, Foamy casts a spell from the book ''Bigger Boobs Through Witchcraft'' on his pet human, Germaine. Her chest swells enormously — a fact neither of them realizes. The spell seems to have lasting effects, as Germaine's breasts are noticeably larger in the later Foamy episodes than they had originally been.
* Since the [[Whateley Universe]] features a significant number of mutants whose "body image template" endows them with superhumanly good looks, it's probably a safe bet that quite a few mutant teenage ''girls'' are going through this while changing. There's also a humorous, if slightly [[squick]]y, example in one of the Jade stories where one of Jade's autonomous telekinetic constructs gets herself equipped with ''artificial'' inflatable breasts operated by remote control to help her serve as an icebreaker at a party. Needless to say, [[Hilarity Ensues]].
* In the ''[[Paradise]]'' setting, humans are being randomly, permanently changed into [[Funny Animal]]s (and sometimes [[Gender Bender|gender-changed]] at the same time). In keeping with the [[Wish Fulfillment]] inherent in the setting, female Changed receive an extra helping in the endowment department over what they had as humans—and those who used to be ''male'' humans [[Attractive Bent Gender|get even more]].
* The content of the Breast Expansion Archive is [[Exactly What It Says on the Tin|just what you'd expect from the site's name]]. Its sister site, the Breast Expansion Story Club (subscription required) is more of the same, but in story form, rather than images. A small sample of what's offered follows:
** ''The Best Cheerleader'': a cheerleader steals a breast enhancement formula to try and give herself huge boobs but it backfires.
** ''New U'' is about a girl who opts to grow larger and more buxom through designer drugs because she's insecure around her taller, more buxom sister, who got them through a similar procedure.
** ''Island of Dreams'' involves an incredibly [[A-Cup Angst|insecure and envious]] flat-chested girl who goes to a cosmetic surgery spa to [[Bigger Is Better|fix that problem]].
** ''Hollywood Hills'' is about an aging movie star with "decreased assets" who undergoes a procedure to try and regain her formerly impressive chest.
** ''Accident'' has some girls exposed to chemicals start growing to ridiculous sizes. One, being a an A-cup, is ecstatic. The others, being huge already, are not.
** ''The Goddess' Fun Shop'' is about a jealous, flat-chested girl who is so upset her sister (who is younger) has huge Boobs that she goes to extreme lengths to get her own. Naturally this doesn't end well.
** ''... Keeps the Autodoc Away'' deals with the physiological issues caused by outsized attributes. Nothing quite like nearly smothering on your own breasts because you got turned around the wrong direction in Low G...
** ''Stranger than fiction'' releases a nerdy secondary charecter back into his own story with the power to bend reality at his whim, and finds himself turning every female he comes across into an overly buxom babe who 'at least' wouldn't say no to whats in his pants.
* Mordred from ''[[Fate Nuovo Guerra]]'' got this as part of her [[Gender Bender]] package from the Holy Grail.<ref>To clarify, due to being a clone, he was inserted into a Servant body based on his mother Arturia, only a couple of sizes bigger.</ref>
* In the online [[Role-Playing Game|RPG]] ''[[Epic Battle Fantasy]]'' Natz the magician of the [[Power Trio|main cast's]] impressive bust doubles when wearing the cowgirl outfit.
* ''[[Skippy's List]]'' has examples:
{{quote|5. Not allowed to get silicone breast implants.}}
* A favourite trope of [[The Erotic Mind Control Story Archive]].

== Western Animation ==
* ''[[Braceface]]'' has an episode where central character Sharon buys a pump to make herself bigger. She ends up overdoing it, with humiliating results. First getting laughed at by the same people she was trying to impress, and then her boobs...pop.
* In the ''[[American Dad]]'' episode "Tearjerker," all the gadgets created by S are all just different vehicles for Breast Expansion technology. As befits a [[James Bond]] parody, the fate of the world eventually depends on Stan making a woman's breasts triple in size.
** In another episode, Stan gives Steve "male" hormone pills in an attempt to get him in with the Jock crowd. Unfortunately, the wrong pills were used and Steve grows breasts. As a result, he still gets in with the Jock crowd. The episode ends with Stan also taking the pills and showing Steve that adolescent males only respond to one thing.
*** Pretty much that exact same plot happened 2 years earlier on ''[[Hey Joel]]''. Just replace hormones with bulk up powder and jocks with Bill Wyman.
* ''[[Family Guy]]'':
** Peter asks Jesus to give Lois huge breasts - in the next scene Lois' boobs grow to absolutely enormous size.
** Another episode had Lois stop breast-feeding Stewie, and her breasts got so big she was popping buttons off her shirt—just in time to save Quagmire from a bad marriage by reminding him ''just how much he'd be losing''....
*''[[WITCH (animation)|WITCH]]''... oh, where to begin?<!--Start by moving the comic examples to their appropriate section.-->
** In the very first episode, after gaining their Guardian powers, flirty Valley Girl [[Rich Bitch|Cornelia]] realized their breasts have effectively doubled in size... and [https://data.whicdn.com/images/246783669/original.gif she's quite pleased]. Hay Lin was more taken in by their fairy wings. 
{{Quote|Hay Lin: "Look what we have behind us!"
Cornelia: "Look what we have IN FRONT of us!"}}
:*For that matter, ''every time'' they transform their breasts [[Fan Service|visibly swell in size]]. In the comic and series, this is actually made a plot point: both Will and Hay Lin, naturally flat, prefer the ego-boost of their new, enhanced breasts.
** In the comics, and in the series, on two separate occasions boy-crazy [[Tomboy and Girly Girl|Irma]] uses her magical abilities to make herself taller and more buxom in an attempt to get older men. Unfortunately both attempts fail hilariously. This is despite the fact she's, in canon, described as being the biggest of the girls, chest-wise: i.e. she's as big normally as the others are transformed: ([http://pagesperso-orange.fr/witchflowers/irma/irma%20cool.jpg before] and [http://pagesperso-orange.fr/witchflowers/irma/irma.jpg after]). [[Gag Boobs|Ironically she gets teased for this.]]
** In another instance, Cornelia gains a temporary boost in power from absorbing the energy of a magical orb, and her breasts grow even larger (as well as making her taller and [[Hourglass Hottie|more filled-out in other ways]]) and Irma suddenly looks ''very'' insecure and crosses her arms across her chest.
** In the comics Will (short for Wilhelmina) is explicitly stated to feel insecure about her underdeveloped chest size, and prefers her [[Bigger Is Better|Guardian form]] to the point of overcompensating by sticking out her chest for no reason.
** In the Halloween episode, the girls assume Guardian form openly for the first time as they can now go out in public without looking weird. [[Hot Shounen Mom|Cornelia's mother]] sees Hay Lin, an Asian girl who is usually flat-chested but now sporting enormous knockers, and embarrasses her in front of the others by implying she padded her costume to make her breasts look bigger. Irma, standing behind her, starts to giggle at her and an embarrassed Hay Lin angrily sticks out her chest to [[Big Breasts, Big Deal|prove otherwise.]]
** In the same episode, Irma, in her very buxom Guardian Form, meets a boy she has a crush on who is quite happy with her... "costume". Which he says [[Male Gaze|while staring directly at her chest]]. Sure, costume...
** In the series, Cornelia was the one, instead of Irma, who both became stuck in Guardian form and tried using her enhanced physique to get an older boy to date her. This was talked about in an earlier episode where they were trapped in Guardian from and Cornelia contemplates dating older men as she's now [[Bigger Is Better|more buxom.]]
* ''[[Robot Chicken]]'' In the ''No Need For Glomer'' sketch of the animated version of ''[[Punky Brewster]]'' where Punky asked an abused Glomer to make her [[Bigger Is Better|boobs bigger]] that went all the way into [[Body Horror]]. This is [[Very Loosely Based on a True Story]]. Actress Soleil Moon Frye, who played Punky Brewster in both the live action and animated series, suffered from [[wikipedia:Gigantomastia|gigantomastia]] and had breast reduction surgery when she was 15.
* On an episode of the animated series based on ''[[101 Dalmatians]]'', the villainess, Cruella De Vil, tries to seduce Roger by putting on a blonde wig and using inflatable fake breasts. Not only doesn't it work she ends up [[Jiggle Physics|bouncing]] so much she literally bounces away. This was a children's show mind you...
* One episode of ''[[Duckman]]'' involves a brief trip to a plastic surgeon, where we see a woman inflating her breasts with a compressed air pump until she ''explodes''. Another featured a short gag about a ray that makes breasts triple in size, as a background gag.
* Happens to Marge on ''[[The Simpsons]]'', who protests to the doctor as seen in the quote above.
{{quote|'''Doctor''' (bored): "Yes, I'm sure your husband will be furious."}}
* In the ''[[South Park]]'' episode "Bebe's Boobs Destroy Society", Wendy gets jealous of Bebe's boobs because they've captured all the boys' attentions, and goes to get hers augmented... Only to find when she returns to school that the boys have gotten over their fascination with them, thus leaving her with ridiculously large breasts. Especially considering she's roughly eight or nine.
* ''[[Ugly Americans]]'': Callie, when she comes into contact with a demon-baby in the third episode.
* In ''[[Stripperella]]'' this happens to said character when the nerds try to return her to her original size. As you can see [http://www.youtube.com/watch?v=1hqJf9zBxv4 here] it is [[Blatant Lies|obviously an accident]].
* In one of the first episodes of ''[[Teenage Mutant Ninja Turtles 1987|Teenage Mutant Ninja Turtles (1987 series)]]'', there's a scene when April O' Neil is tied to a chair. As Michealangelo loosens the ropes, her breasts [[Hidden Buxom|visibly expand in size]]. It probably could had been an unintentional animation slip-up, though; but April's expression [[Fan Service|says otherwise]]. See it [http://www.youtube.com/watch?v=b7STftx6vz8 here].


== Miscellaneous ==
* [[Rule 34]] is fully in play here.
* Subverted by a birthday card of the late 90s; a flat-chested girl wishes on her birthday candles for cleavage. Her butt grows to immense proportions.
