* The content of the Breast Expansion Archive is [[ExactlyWhatItSaysOnTheTin 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 from a rival 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 [[ACupAngst insecure and envious]] flat-chested girl who goes to a cosmetic surgery spa to [[BiggerIsBetter fix that problem]].
** Bronwyn jokes with her friend in ''Fairy Tale'' that her breasts are so big because the boob fairy is in love with her. Unaware of course just how accurate her statement is, she gets another visit from the fairy during the night...
** ''Hollywood Hills'' is about an aging movie star with "decreased assets" who undergoes a procedure to try and regain her formerly impressive chest, and finds herself gaining more than what she had.
** ''Til She Gets Her Way'' has a normally flat and short girl whose tired of being pushed around gain the power to grow in various ways until she gets what she wants, but can't stop the growth until she gets it.
** ''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.
** ''Spore'' involves a couple of high schoolers working on their science project, a hybrid mold with unknown properties. Someone however forgets to keep her mask on while working with it allowing spores to infest her body. Leading to some 'not unpleasant' swelling. And then it gets in the school air ducts...
** ''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...
** ''Spells R Us: Dream Girl'' takes a trip into Bill Hart's ''Literature/SpellsRUs'' universe about about [[TheLittleShopThatWasntThereYesterday a travelling shop]] visited by an overweight girl looking for something to land her the school's quarterback. The owner gives her a potion that will turn her into the young man's perfect woman. [[BeCarefulWhatYouWishFor Unfortunately]] she finds out the boy's [[MyGirlIsASlut perfect woman]] is not one she wants to be.
** ''Webcomic/WelcomeToChastity'' 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 a whim, but believing the previous stories main character to be the one changing things, 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.
** Scarlet the Red in ''A Pirates Life'' finds herself under a curse that causes her breasts to grow every time she takes what isn't hers by right. Unfortunately she's a pirate captain, and the actions of her crew reflect upon her too.
** ''Educational Endowments'', in the style of Film/TheBreakfastClub, is about 6 students find themselves taking a test to determine whether they graduate or repeat their senior year in high school. After being partnered into groups of one boy and one girl, they discover that the test grade will determine not just their future, but also the female partners breast size.

* In "Literature/DorkDiaries", a rather humorous parody of ''Literature/DiaryOfAWimpyKid'', 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 ''American Pie Presents The Book of Love'', an imaginative nerd fantasizes a pretty girl taking off her top where her chest ''quadruples'' in size with some movie magic. Hilariously, they grow so massive that they literally pop to burst his bubble and snap back in reality.

* This is the main premise of the UsefulNotes/PlaystationVita {{Roguelike}} ''VideoGame/OmegaLabyrinth''. 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.

* In ''Anime/QueensBlade'', 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 is coated with wax, making it immune to Melona's acid. Knowing she's [[SuperWeight 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 BigBad. 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).

* ''Manga/YuunaAndTheHauntedHotsprings

** In Chapter 77, both Hakari and Karane get into a bath that enhances their chest size. Karane refuses to leave it, knowing that her chest size will return to normal once she does, but Hakari manages to talk her into doing so.so.

* In the ''WebOriginal/{{Paradise}}'' setting, humans are being randomly, permanently changed into {{Funny Animal}}s (and sometimes [[GenderBender gender-changed]] at the same time). In keeping with the WishFulfillment 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 [[AttractiveBentGender get even more]].
