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 what is more than likely THE absolute kinkiest Undertale fanfic of all time, Asriel, after watching way too much Alphys VS Undyne, decides to re-enact the series' infamous giantess Alphyne scenes, only with him and Toriel! Needless to say, things get REALLY fetishistic and REALLY fucked-up REALLY freaking fast; trust me, you have been warned.

Summary: Aaron is face-first on the rug in the front hallway after a night of drug-hazed partying. How is his mother going to get him into bed if she can't even lift him? Portasizer to the rescue!

This is a PoisonPen story. You know what to expect. If you don't, then I advise you not to read it. It's only rated "X" because there's no rating of "PoisonPen" available. Only 4000 words, and not much exposition or back-story. Just straight to the action. I'm planning on writing something longer over the holidays, so I wrote this to get me warmed up, Enjoy.

Summary: (ORIGIN: Chapters 4-5.5 of HBACSAPS)

Just when you think that Xander's brain fetish simply can't get any worse, this scene (hell, pretty much the entire Grinch-spoofing story that it came from, for that matter) comes along and proves you wrong...and yes, I'm well aware that that rhymed.

Despite being an incredibly great and overlooked fanfic that just so happens to be a remarkably clever and affectionate parody of no less than three different things at the same time (Undertale, xandermartin98's fanfiction library for it, Dr. Seuss' Grinch) with some really phenomenally executed writing and humor (and fap material), I can still admit that this story in particular gets REALLY out of hand with the whole brain thing, with this scene being easily the absolute definitive example.

Personally, I would highly recommend bringing a good amount of brain BLEACH for what ends up happening here; seriously, don't be fooled by the fact that it starts out as a perfectly normal Donald/Hillary election parody speech between Bratty and Catty, because before you know it, the story pulls a lesbian SIX-some on you, with two of those six actually being mutated synthetically cloned pieces of Bratty's and Catty's brains (that Alphys and Undyne are busy having SEXUAL INTERCOURSE with, naturally enough).

Hello once again everyone, 'tis I, Error, and I am back from a disappointingly long break after my surprisingly decent story, Circle of Goddesses, and my disappointment, A Mother and Her Son. Yeah, boo, I wrote that story in like 10 minutes because I was bored. Anyway, this is going to be my next large story. I have no idea how big this story will be as of now, so don't expect any solid storylines from me yet. Other than that, I hope you all thoroughly enjoy my next piece of work: It's a Wonderful Life.
