Breast Expansion

Breast expansion is a fantasy fetish genre that concerns several different means for women’s breasts to become larger. Within the fetish, breasts can get bigger as a result of growth, inflation (by air, water, or something else), implants, or “attribute theft”, which is when one woman somehow steals the breast size of another woman or women. (There’s even at least one artist who has breasts fill up with worms, but that one gives us the willies.)

Growth Comics focuses on breast growth in our comics and stories, though attribute theft can be a lot of fun, too, and we don’t want to rule it out.

Breast Expansion spreads through a law firm! An attractive, hard-working young woman, Julia is trim and very fit, but there's one thing about her figure she doesn't like: she's small breasted One night while she's waiting at the bar during a work function, she confesses to a stranger that she envies the ample busts of some of the women at work. He hands her a card with just one sentence written on it – "What if my breasts were one cup size larger?" – and tells her that reading it aloud will make it happen.

Initially, Julia dismisses the card as nonsense, showing it to the women she works with. Julia's busty rival at work, Kendall, glances at the card and reads it aloud as a joke, then says, "That’s the last thing I need!” But when they arrive at work the next morning, Julia sees that Kendall's breasts have grown – they're even more impressive than before! Having seen evidence that the card actually has the power to change her body, Julia and some of her friends soon make use of the card and their enlarged breasts begin to have unpredictable effects on their lives: professional, social, and sexual.

Each time a woman reads the card aloud, her breasts soon grow one cup size larger. Julia finds herself unable to resist using it again, and again. Formerly flat as a board, soon Julia has the largest breasts of any woman she knows, and yet still the temptation to grow larger nags at her. How big will she get?

And how many other women will get huge boobs, too?

Building Brand

Ryan thinks he's found the secret to improving his modest physique, transforming him from skinny punk to brawny hunk without having to bother with the big, heavy weights in the basement -- a magic muscle cream that can make him the strongest man on campus.

Of course, before long the muscle cream falls into the hands of his younger sister and her friends. The girls proceed to misuse the product, experiencing greatly increased female muscle growth that transforms them into busty amazons, with big, bulky biceps and bulging bosoms. Ryan soon finds himself facing off against three young women who have each grown fantastically strong and more muscular than he ever dreamed he could be.

With the only way to catch up being to also disregard the instructions, Ryan takes a chance. But will it result in him outmuscling the girls, or dwindling to pee-wee size, with even less strength and muscle mass than he had to start?
