Expansion: Bigger Really is Better, or At Least More Fun
This is the third essay in my series on erotic transformation.
There are so many aspects to the expansion fetish that I almost wonder whether there’s too much to talk about in one essay. When it comes to making body parts bigger, we seem to have endless fascination, and endless variety, but I think there’s enough in common here to pull it all together, so let’s give it a try.
Expanding a body part in an erotic story focuses attention on it. The story is about that body part, as much as anything else. From that focus, the part in question can be a metaphor for something else, or it can be an erotic stimulus, or both.
Generally speaking, the expansion goes beyond anything natural or artificially possible in the real world. After all, there’s not much point if you’re going to stop at a size that could be explained easily.
First on my list is breast expansion. Lots of people love breasts, men and women alike. Making them larger also increases the attributes that people like about them: their softness, their roundness, and their visibility. In my experience, breast expansion fetish material will emphasize one or more of these aspects in its description. Boobs can be used as pillows, for example, or even slept on like a bed. The work of Chinese sculptor , as nearly perfect spheres; sagging breasts are not often found in breast expansion. And many of the stories feature breasts growing fast enough to burst out of clothing—after all, these stories are rarely bounded by real-world biology. Looking behind the eroticism, one can sometimes find an essential paradox of being a woman; the enormous breasts often have power (the metaphor can go so far as destroying buildings by growing) but are also a tremendous inconvenience. I’ve written a few of these, most notably episode 233, Merys at the Font.
When the thing that’s growing is a penis, the attributes that are likely to be highlighted are lack of the owner’s control, visibility, and ejaculation. The big one here is lack of control; in these stories it is very common for the owner to get erections at the most inconvenient times, which plays over into the visibility aspect. Usually, the volume of ejaculation is enhanced along with the penis, sometimes well beyond the proportions of the organ in question—see the previous paragraph regarding scientific plausibility.
The next erotic growth transformation is one labeled “FMG” or Female Muscle Growth. This overlaps a good deal with another transformation style, Giantess, so for purely taxonomic reasons I’m limiting it to transformations where the woman can still fit through a doorway. While breast expansion is, more often than not, puts women on the submissive side, female muscle growth is solidly on the dominant side. It takes fem-dom fiction and turns the metaphorical into the actual; I don’t know of a single FMG story where the newly created amazon doesn’t take the dominant role in sex.
The dark mirror to FMG is weight gain. In this sort of story, a woman gains an extreme amount of weight in a short time. Often she quote-unquote “deserves” it, for one misdeed or another, but sometimes she’s naturally thin and wants to be bigger. Sometimes there’s little vanilla sexuality in the story at all, and it’s more of a revenge story. Other times the “ultra voluptuous” body is an honest turn-on, with the author swimming upstream from popular culture.
Last of all is the expansion fetish called ‘inflation.’ This fetish is no less improbable than the others, but it takes its implausibility out and flaunts it. It’s rule 34 of the internet at its finest: take the cartoon convention that you can pump air (or helium, or water) into someone, and they blow up like a balloon without injury. That’s it! Simple. There are even rubber suits for folks to act this one out, believe it or not.
In general, expansion stories are less likely to be much more than wank material. Either you like this kind of story, or you don’t. That being said, it constitutes a pretty large proportion of the erotic transformation sub-genre. Personally, I think that’s because it’s so direct and to-the-point.
