Summary: In the official finale to Alphys VS Undyne's incredibly disturbing giantess offshoot series, we learn just how fucked-up things can really get in it.

And by "how fucked up", I mean as in Alphys invading Toriel's brain in just about the most painful way possible without killing her, then mind-controlling her into brutally raping her own son and husband in just about every single way possible, prompting them to then rape HER back.

Now THAT'S some fucked-up shit, Undertale fanfic or not.

Summary: In a far more intensely fetishistic and disturbing role-swapped sequel to the Giantess Alphys X Undyne scene from Alphys VS Undyne, Undyne shrinks Alphys to nearly microscopic size and shows her what REAL giantess femdom is...luckily, however, Alphys still has a few tricks up her sleeve! Can you guess which ones I'm talking about?

Summary:

One day, for reasons that escape your comprehension, you shrink really small (ranging from about 1/2 inch to 1/10 inch or 1cm to 1 millimeters approx.), and you don't really know why. Did someone do it? Did something cause it? Who, or what? Unfortunately for you, you won't get many chances to find out, as you have to try your best and survive as you're not alone. The girls that you were just hanging out with or happened to be around are now seemingly impossibly gigantic. You might try to alert them of your presence, but that might not end up being the best idea.

[This story is sort of a spiritual successor to TinyMan0001's 'Giantess/fart shrinking' stories, though not intended to be a carbon copy of it. One difference is that whether farts shrink you is up to whoever is writing, though I at least chose to leave the cause of shrinking mysterious at the beginning, and also because it slightly contradicts some backstory (I also left open the possibility for a girl to intentionally shrink you). However, like it, it's largely focused on the shrinking side, though I guess I can leave a branch dedicated for a giantess/growth route if anyone's interested on adding to that. Also, similarly, the girls may be aware or unaware of your shrunken form. Usually, I'd say they should progress from unaware to aware, depending on the girl and the situation though.

This story is a more user-friendly display for the interactive I made at Writing.com, though here we have to do away with the ability to have other people directly add chapters, and instead I'll be posting the more relevant routes done so far.

PS: The Giga tag was just selected in relation to the main character's perspective, this is mostly a shrinking story, not growth focused, though a growth route may be done in the future.

Summary:

In this alternate timeline taking place during Season 1, Bloom is walking around the city when she bumps into a young man named Adam Barnes. Two months later, the two finally get set for their first date... on the beach, no less! Tecna offers Adam a new fragrence she's been working on, and he sprays it as soon as he arrives at the beach wearing his blue Speedo. The young college student not only grows to almost 190 feet tall, but he has quite a bit of muscle to go with it! Bloom, wearing her green two piece bikini, finds the giant and muscular Adam irresistable, but he doesn't want to feel alone. He points Bloom to the fragrence bottle and after a quick spray, Bloom grows to 180 feet tall. The two swimsuit-clad giants then make their way to the city, being as careful as they can be while figuring out what they'll do for their (literally) big date.
