Breast expansion

Jump to: navigation, search

Breast expansion fetishism is a sexual fetish characterized by pronounced sexual fantasies involving a female whose breasts enlarge, either gradually or suddenly, sometimes to gargantuan proportions. Breast expansion fetishism may manifest as a form of inflation fetishism.


Real-world breast enlargement

Many breast expansion fetishists are fascinated by the processes by which women’s breasts can become larger, whether from age progression, pregnancy, weight gain or surgery. It is not uncommon for them to examine closely the careers of adult and mainstream entertainers and their increasing, or decreasing, bust sizes.


Breast expansion stories are often fantastical tales of women’s busts being enlarged by air, food, magic, medicine, Extraterrestrial life (aliens), technology or some other unseen force. Generally, the amount of enlargement is limited only by the imagination of the author, from as little as a cup size to as big as room-filling and beyond. Occasionally, there are other types of fetishes included in these stories, such as lactation, anthropomorphism, giantess, transgender, body inflation, penis expansion, or any of the processes under the umbrella term transformation fetish. Stories and pictures associated with breast expansion sometimes contain vivid depictions of sexual activity, but it is not a necessity of the fetish.

internet, they have appeared in print. Men's magazines have featured breast growth stories since long before the internet and there have been publishing companies that have specialized in the fetish. White Lightning Productions (1997-present) produces anime-style comics with strong breast expansion themes. E.L. Publications, which went out of business in 2006, produced illustrated breast expansion and macrophilia stories.

Two examples of movies with breast expansion are Bruce Almighty and The Stepford Wives, and there is a video series Dream On, that "may be the first series to proclaim publicly almost every week that it has a breast fetish."


Many breast-expansion fetishists are morphers. A Morph is a photograph, or an artwork or an animation which uses morphing techniques to expand a woman's breasts; some examples of this can be found at the Breast Expansion Archive User Gallery.

Breast expansion is a recurring theme in some anime and manga.

  • In the anime series Ayashi no Ceres, a young girl’s skirt and blouse burst open as she transforms into a young woman with larger breasts and deep cleavage.
