"You've turned my maguppies into bazongas!"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 frequently played for comedy, but this still ends up providing Fanservice. An Overnight Age-Up for women usually guarantees this will happen. If the expansion is merely caused by puberty, there's a separate trope for that. If the expansion is done on a meta-level see Adaptational Curves. An alternative is Fake Boobs.

Anime & Manga
- 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.
- In an early chapter of the quite obscure manga Benten-sama ni wa Iwanaide (loosely, Don't say that to Benten), this trope is magically invoked by a selfish and petty guy who uses the goddess Benten's power as part of a convoluted plan to publicly humiliate a woman who rejected him. The target's bust begins to slowly and steadily grow (as a convenient digital readout conveniently tracks her gradual progress from 80 to 124 centimeters), and in the meantime she rashly agrees to fill in at the last minute for the role of a princess in a children's play, which naturally involves wearing a very tight-fitting costume. Between the enchantment's progress and her fellow actors' energetic antics, the result is as predictable as it is spectacular.
- In Black Butler, episode 23, a slightly-endowed Angela tries to tempt Sebastian by showing off her assets, and they actually look bigger than in previous episodes. Possibly justified by the fact that she's not human anyway.
- In Change 123, when the main character's split personalities manifest, her appearance changes due to subtle differences in the placement and internal balance of her muscles necessary for their different combat specialties (attack power, speed, and defense). The usual sign that the childish grappling specialist has come out is that her boobs instantly "grow" big enough to snap her bra (or bikini top on occasion). Presumably this is the result of her pectoral muscles pushing them farther out than usual.
- In one Crayon Shin-chan episode, Misae imagines herself with hugely enlarged breasts.
- In Cyber Team in Akihabara, Kamome one of the five Magical Girls 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.
- 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.
- Chapter 4 in the manga Franken Fran featured the titular character (an insane Body Horror plastic surgeon-cum-Frankenstein's Monster) passing out free cosmetic surgery to some kids at a school that yields almost instant results with no recovery period. Besides odd instances like a couple who wanted to be stitched together, or having a love message drilled into your teeth, one girl apparently asked for 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 she's right.
- The Gag Dub of Ghost Stories 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 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 "heavy" but in the end she decides to keep them.
- 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 show off for her friend it appears.
- Subversion: Once, 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,) Miki sprinkled this dust on Kyoko's chest. It inflated... inflated... 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.
- 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 just stare at her boobs.
- Episode nine of Kamen no Maid Guy features an entire restaurant which hires only busty girls so the waitresses can use their assets to distract the predominantly male customer base from 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.
- Magical Canan's protagonist Chihaya has a mild issue on her small bust. When she transforms into her alter ego, Magical Girl Carmine, the camera intently zooms on how she grows her breasts and butt's sizes. They shrink back when she turns to normal.
- Magical Girl Lyrical Nanoha 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 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.
- 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, Shikijo, and even the male Suguru, but not on her.
- 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 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... in a dream sequence.
- At the end of the story, Nodoka's breasts have started to grow as a result of being in low gravity.
- In the manga Manyu Hikencho, the story is set in a fictional fantasy world where 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 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.
- 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 Mini-Moe into a buxom hottie.
- A rare non-human example happened in Mazinger Z. In episode 32, Kouji and Sayaka have to battle a flying Mechanical Beast (Gelbros J3). Kouji thought replacing Aphrodite A's Torpedo Tits for bigger missiles would help to defeat it. It Makes Sense in Context.
- 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, she keeps some of the expansion. It happens a few more times throughout the series.
- 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'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".
- In Pokémon's episode "Beauty and the Beach", 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.
- In Puni Puni Poemy:
- One episode sees some of the characters (including the Token Mini-Moe) imagine what they would do with the titular character's magic powers...two of them, including the Token Mini-Moe, imagine them making their breasts larger.
- While the girl with Gag Boobs pulls the inverse, imagining a world where she's finally flat and free of back pain.
- In Queen's Blade, the character Melona (ironic name) can fire corrosive liquid from her breasts as an attack. When Leina fights her a second time, she has a countermeasure: a special suit of armor that for some reason or another is immune to Melona's acid. Knowing she's outmatched, Leina tricks Melona into attempting an acid attack before dashing up and grabbing Melona in a bear hug. The acid backs up, and inflates Melona's breasts to the point they explode, killing her. Of course, lucky for her fans, it was just the first episode and she's quickly revived by the Big Bad.
- Melona is a demonic blob creature in human shape whose body consists of highly acidic jelly, so there is some explanation for how she does this (as well as survive).
- In Rosario + Vampire, removing Moka's rosary causes her true vampiric self to emerge. In addition to a massive increase in power and a change to her hair and eye color, the transformation causes Moka's (already fairly noticeable,) breasts and buttocks to enlarge even further.
- Yukari has an imagination spot where she pictures herself with breasts bigger than Kurumu, before they grow so big the imagination spot pops. This was in the same episode she had aged into a teenager where the only one bigger than her was the resident succubus.
- 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."
- 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.
- In The Qwaser of Stigmata, Oribe Mafuyu's breasts grow from one of the smaller girls in the series, to the biggest, thanks to the use of her sword which draws energy from breast milk. In the manga this also happens, but over time rather than all at once like in the anime.
- A subversion occurs in Slayers when flat chested Lina Inverse was told of a fountain that makes things grow as a reward for a quest. It turns out the magic spring she was told of would have made her old.
- In To Love-Ru, one chapter has Golden Darkness use her shapeshifting powers for this purpose.
- In a chapter of the squel 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.
- 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.
- UFO Ultramaiden Valkyrie:
- 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 Boob capacity as they turn into their adult forms.
- In UQ Holder!, Dana is able to make Yukihime's breasts and butt grow, giving her the appearance of a fertility goddess. It's a sign of how powerful she is, since she was able to ignore Yukihime's incredibly strong barriers.
- When three of the angels in Wedding Peach switch bodies with magical cats, the girls turn into Cat Girls, and their breasts grow. Their breasts shrink back after the girls return to normal.
- The Firesign Theatre had a fake advertisement for "Boobie Chew", a gum that would make your breasts larger, on one of their albums. "Boobie Chew will grow on you!"
- In Genšł, 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 humor 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 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 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 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. 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 Magical Girl form to offset her lack of size, while tomgirl Irma is already the biggest, but tries to make herself bigger anyway out of pure vanity.
- 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. Given the nature of the series this is probably 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.
- Another comic known as C.H.I.X, a parody of many of the tropes associated with heroines. Its main character 'Good Girl' is a Flying Brick who stores energy in, and whose powers and intellect are proportional to the size of her breasts (the bigger they are the dumber she is). She starts out the comic giving a heartfelt speech, but only a few panels in her breasts grow back from flat to huge and she forgets what she was talking about.
- 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), and Cat Grant (from Superman). Jessica Drew is a maybe...depending on how you interpret this◊
- The writer for that comic in which that panel took place outright said it when comparing Spider-Woman with Wonder Woman "Spider-Woman has better hair, better costume, Frank Cho implants and a fucked up origin"
- As it happened, 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.
- The aftermath of the Conquest event in Invincible, Eve reforms her body from scratch; after awakening in an intense care unit Mark is happy to see that she's alive and fine, then he notes that her boobs look bigger, Eve remarks that when she rebuilt herself some "improvements" were unconsciously made. That said, her bosom doesn't look any different than usual, Eve was always quite busty since day one, the way Mark immediately notes how bigger she is now doesn't match the unnoticeable "change" in her actual design.
- Later it turned out that Eve was pregnant, which may have had something to do with it.
- Little Ego had a story in which Ego found a cream that caused her breasts to grow. Although initially delighted, they continued to expand till they were too big for her to exit the room. Being a Little Ego story, it was All Just a Dream.
- Miss Adventure, from Penthouse Comix, transforms from flat-chested to incredibly buxom when she transforms into a superheroine.
- In the Naruto and Kenichi: The Mightiest Disciple crossover Naruto Rebirth of the Rikudo Sennin, Thanks to Naruto's strict diet and training regime Kisara goes from Calling Miu a milk cow to worrying that using the name would be hypocritical since she's now the bustier of the two.
- Two examples in Webwork: Jade notices that her new spider demon body has larger breasts than her previously met future self. Later on her old teacher finds that her breasts are bigger after her own transformation into a bat demon.
- In Thousand Shinji, when Rei transformed into Reigle, she used her control upon her body mass to expand her breasts.

- In When Evil Calls, one death scene features a nerdy girl who gets inflated from flat to 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.

It works at first, but soon backfires spectacularly, as she keeps getting bigger and bigger and eventually 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, but it's implied otherwise (keep in mind this is a 12 year old girl). She's surprised and embarrassed when she gets teased for her overinflated look by the other girls. Guys however are way more impressed.
- It's also implied her parents forced her to get them. It's a pretty messed up book series.
- 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 made from the secretions of psychic genetically engineered monsters, so it causes horrible problems to all the test subjects.

- 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.
- An early 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 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 it didn't stop anyone from trying. Yes it was that important to them!
- Subverted in 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.

- The Benny Hill Show:
- A sketch depicts an harassed young woman at a bus stop suddenly transforming into She-Hulk. The early stages of her transformation memorably show her flat chest (under a T-shirt bearing the legend LUDO) expanding and EXPANDING... until eventually, the word LLANDUDNO is stretched amazingly tight over her ballooning bosoms. Only THEN is a loud ripping sound heard. Disappointingly, when we then see her transformed, while she's undeniably attractive, her balcony just doesn't measure up...
- In another sketch, Benny plays a man helping a woman pump a flat tire on her bike. Instead of the tire inflating, her breasts grow. Cue Aside Glance.
- An interesting male example is the three Ferengis fantasizing about getting "lobe expansions" from the sales of Seven of Nine's nanoprobes in the Star Trek: Voyager episode "Inside Man."

- David Brody's Make My Boobies One More Size.
- 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.
- The "Growing Up Skipper" Barbie doll. See here.
- 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.
- In the Touhou fanworks, BE is the dream of several of the rather under-endowed girls, including Sakuya and Youmu. Numerous ways to achieve this end exist, from suspicious mushrooms picked by Marisa to Eirin's shady drugs.

- Actually part of the gameplay in Bunny Must Die! Chelsea and the 7 Devils — 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 increases her attack and defense, but reduces her speed and jumping ability.
- Her default stance is actually based on that form. Otherwise, she's leaning forward for little reason.
- In 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.
- In the first game, there's also a spell to explicitly increase bust size... but rather than using it to enlarge breasts, you use it on a stone bust of the school's founder, making it bigger so you can climb into the school's stacks.
- Inverted in the intro of Dragon Age II. During said intro, Bethany, the Player Character's sister, has huge breasts as does a female Hawke. Once Cassandra tells Varric to stop exaggerating and tell the story how it really happened, and the game starts for real, they're suddenly much more reasonably sized.
- Rather interestingly, both played straight and inverted in Lightning Returns: Final Fantasy XIII. With each Garb design, Lightning's bust size notably increases or decreases. While Chainmail Bikini-type armors obviously ups her bust size note , masculine-type Garbs (such as the butler-esque Loyal Servant and Velvet Bouncer) makes her practically flat-chested, so much so that female NPCs may hit on her before realizing he's a she.
- Happens with most CPU's in the Hyperdimension Neptunia games whenever they activate their HDD forms. Neptune, one of the main characters, goes from flat-chested to a generous E-cup, for example, while Vert's already big breasts get even bigger. Averted with Blanc, who stays as flat as she was (much to her chagrin) and inverted with Uni, whose breasts actually get smaller.
- This is the main premise of the PlayStation Vita Roguelike Omega Labyrinth. The story is about a girl hoping to enlarge her breasts is seeking an object called the "Beauty Grail", which lies at the bottom of a monster-filled dungeon. Killing monsters releases "omega energy", which is stored in the player character's breasts, gradually causing them to grow from an a-cup all the way to a k-cup. However, all this energy is lost when you exit the dungeon; presumably the Beauty Grail is needed to make the transformation permanent.
- Ryōbi from Senran Kagura is normally flat-chested with the usual angst that follows. Her transformation, however, gives her a fairly sizeable pair, more in line with just about all other characters.
- In Slimy Thief Aisha's body was merged with a slime creature so now certain parts of her body grow when they touch water. She regards this as a curse but notes that there are some advantages, one of which being that she can make her breasts as big as she wants.
- While it has yet to occur in the main story, these two filler strips of The Wotch have this happen to Anne.
- A theme in many of the webcomics by Lightfoot.
- In (the rebooted) Pulse, super-heroine wannabe Annie Chang participates in an experiment to increase her barely useful natural electrical powers. While the process was successful, the skinny girl develops a super-heroine physique, including boobs that are at least huge. Leaving her embarrassed and awkward about her body.
- Some of his older, now cancelled comics displayed this theme more blatantly, before he decided he wanted to focus more on the story and characters:
- In (the original) Pulse, Annie Chang, a former flat chested girl gets superpowers through a Freak Lab Accident and as side effect experiences breasts that grew by noticeable amounts throughout the series. Eventually, her partner makes up a story to the press that she's a robot and the breasts are actually missiles. Annie also has an old friend who initially appears huge, but is in secretly flat and must take a special pill regularly to remain buxom. In the last issue of the original run a scientist was able to secretly drug his female co-worker with a chemical which would cause any excess fat to go to her breasts, and judging from her increased appetite she may not be unaware of it.
- (co-written by Wolfman 1066) Peeveed dealt with a down on luck main character, named Eve. Things changed when she finds and becomes the master of a female genie thats obsessed with big breasts. As with most comedies involving genies Hilarity Ensues and through the course of the series she goes through breast expansion a few times, ironically not once did she wish for bigger breasts. The effect would wear off each time and she would have returned to normal by the next story, Though in one case her flat friend retained her new size.
- There's also My Big Life. About 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 huge breasts to nothing more than an inconvenience. Any change was implied, her natural body was never shown, nor the process of her changing.
- In a short Kim Possible fan comic titled 'Possible Envy', Kim and Shego are competing in a swimsuit compitition were they continually try to upstage each other by being blasted with breast expanding ray guns. By the end of the comic no woman in the area escapes without breasts bigger than their head, and at one point bigger than buildings!
- In two short Teen Titans comics. Starfire and Raven respectively get this treatment. In Ravens case she grew failing to stop the 'prophecy of the giant bra', And Starfire grew massive from some sort of biological reaction from eating pink coloring.
- His most blatant example of this trope was a Final Fantasy fan comic called Missing Materia. Yuffie gets her hands on a rare materia that causes growth and she abuses often, sometimes just to annoy people, all the while Materia from all over the world is mysteriously vanishing. By the end of the comic nearly every woman effected has breasts so big they can't move.
- In (the rebooted) Pulse, super-heroine wannabe Annie Chang participates in an experiment to increase her barely useful natural electrical powers. While the process was successful, the skinny girl develops a super-heroine physique, including boobs that are at least huge. Leaving her embarrassed and awkward about her body.
- Calamities Of Nature features a series of comics in which a character invents helium breast implants so that women can have larger breasts and lose weight at the same time.
- 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.
- Eerie Cuties: Invoked twice. The first instance was to demonstrate that succubus puberty can be abrupt at times. The other happened to Prof. Twigget, as a result of the Tiresias Orb bonding with Blair's mind.
- Wapsi Square: Siren puberty works much like succubus puberty in the preceding example. Which makes it a cause of concern for 15 year old Atsali, since Sirens are commonly believed to have as sexual predators.
- 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. Predictably, the opposite occurs.
- 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.
- A defunct webcomic by an artist named "Jae", titled simply ''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 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 one of the powers Prince Albert has over his bratty older sister in Blooming Faeries.
- Any woman who has sex with Sir Thane, no matter how flat or unpleasant looking they were before becomes beautiful with large breasts.
- in The Whiteboard, a pot of Klatchian Coffee grants the women who drink it a temporary increase of their bust size.
- The origin of Spinnerette's "Ms. Venus"/"Super MILF" (seen in marginally-NSFW flashback) involves an alien biological nanoscale tokamak reactor cluster implanting itself in her bosom via a Freak Lab Accident. In addition to the superpowers, this causes immediate shirt-ripping and necessitates a Cleavage Window (to dissipate waste heat).
- We later see the origin of Greta Gravity, which plays out similarly except for the fact that she puts on weight all over. Still, you can imagine where the focus is.
- In Jix, Lauren (the only human female character) has had this done to her off-screen because Lamerix (the techy character) often uses her as a human guinea pig. Lamerix is testing a breast enhancer device so that she can market it to her alien species. (She figures the male Ambis, her species, would enjoy it and it may make nursing easier.) The real reason, or so the author claims, is to make the female Ambis look more feminine since they were originally designed flat-chested.
- In Held Within Strip #13 Susie tells her girlfriend Jenny that she first noticed her when Jenny's breathing made it look like her breasts were expanding. Later on in Strip #21, when Jenny starts changing into a genie, her breasts really do expand.
- There are several pay-for-view webcomics that have Breast Expansion as the major theme, often going under a banner like "BE Story Club", with several different series encompassing different methods and sizes.
- In the "Amplified Bible" episode of the 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 until the next episode where they are so big she can't get sit up, and they still kept growing. The spell seems to have lasting effects, as Germaine's breasts are noticeably larger in the later Foamy episodes than they had originally been.
- In the episode "A change of Heart" after her breast reduction surgery Germaine expresses an interest in A magic ring that lets her control her breast size. Foamy points out it defeats the purpose of her reduction, to which Germaine replies she only hated them because she couldn't turn them off when they didn't benefit her, having grown to rely on them for big tips and discounts from horny men. She later plays with the ring in the bath, making her breasts bigger and smaller via putting on the ring, and at one point makes them so big that her stalker's head explodes at the sight. As of "Big Tips", she is actively using the ring to make her breasts large while at work to make back the tips she lost.
- 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 squicky, 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.
- Rather less humorous (for Phase) was when Belphegor sabotaged a serum made by Jobe Wilkins with the intention of reversing Phase's Gender Bender status. Unfortunately, not only did it fail, it failed spectacularly: his breasts, rather than shrinking, grew to Gag Boobs proportions, and continued growing for several hours while Jobe worked to reverse the effect.
- In the Paradise setting, humans are being randomly, permanently changed into Funny Animals (and sometimes 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 humansand those who used to be male humans get even more.
- The content of the Breast Expansion Archive is 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:

- Welcome To Chastity has a flat chested girl move to a mysterious town were all women have breasts from huge to 'makes up most of your body weight', and those who don't will eventually find themselves growing bigger and bigger.
- A side story called Tara's Story is about the sister of one of the characters in Welcome To Chastity and her journey of going from a c-cup (outside Chastity), to the bustiest women in town. Which in a town where breasts as big as your head is considered normal is saying something indeed
- Stranger than fiction releases a nerdy secondary character back into his own story with the power to bend reality at his whim but no idea that he is the one controlling it, and finds himself turning almost every female he comes across into a tall and overly buxom babe, most of whom 'at least' wouldn't say no to what's in his pants.

- 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.

- On the series the comic book is based, W.I.T.C.H., the characters transform into Guardians granting them wings, power, and a temporary instant puberty growth - which includes growing larger breasts. The typical fan-service associated with this trope is Downplayed but the difference in breast size is sometimes addressed or used as a plot device.
- Sgt. Hatred of The Venture Bros. grows breasts throughout season 5. His first assumption is to blame the radiation that caused freakish mutations in a bunch of interns, but that turns out to be coincidence. The real culprit is his anti-pedophilia medication interacting with the Super Serum that caused his pedophilia in the first place. He handles the development rather well, until the breasts suddenly vanish before season 6.
Sgt. Hatred: All right, all right. See these man-boobs here? Well, they kinda turn me on. Sometimes I look at them when I masturbate and pretend they're on a lady. There. That's a death confession.
Dr. Venture: I can beat it!
- Dr. Hideto Tomabechi, an acoustical engineer, developed a ringtone which increases breast size by using subliminal messaging, specifically the subliminal sounds of a crying infant. This triggers a biological response in a woman to enlarge the breasts so they can feed the child. However, it takes ten days of listening to this ringtone twenty times a day to enlarge the bust by 3 cm (though that is 50% more effective than predicted).
