Doin' It Right (ON-HOLD. Will resume on December 2025!) by vidrioborroso
Fandoms: Undertale (Video Game)
31 Jul 2025

Summary
Monsters are free, and Frisk is safe and sound at home.
It feels like fairy tales are real, though a rough break-up after eight years of marriage quickly sobers that thinking.
With the break-up follows a proposal straight out of a steamy novel: share a room with a man you've just met, while you get back on your feet and work on the process of finding a new place to move into.
Turns out, the guy who smells like grease and beer from how often he visits Grillby's is a lot less romantic than you would think.
And it's precisely living together what gets you to know all the icky things about him.
Until you end up falling for him with each nice little thing he does, and suddenly...
It feels like all those icky things start to matter less and less.
More so, when things take a sharp turn and you're in the middle of a gang fight, helping him however you can despite not knowing what you're signing up for.
Overlooking details like bloody clothing, chipped teeth, and reports of missing people on the telly make seeing him drinking straight from the milk carton a much more tolerable offense.

Summary
After Sans had the genius idea to mess with a machine he had created, he didn't expect that it would have brought versions of himself and his two brothers (Papyrus and Wingdings Gaster) to their universe. Nor did he expect that an old friend of his would introduce him to none other than his soulmate, or that his very soulmate was also his brother's and alternate versions' also.

Summary
There's two new skeletons in the house.
Unfortunately not much of a surprise there, the machine kept malfunctioning and kept bringing in alternate versions of Sans and Papyruses into their universe. They were up to SIXTEEN SKELETONS, now eighteen with the two's newest arrival.
Except... there was something off about the new skeletons. 'Visor' and 'Chine'.
Sweet mercy above, these two brothers seemed to hate each other. They kept swearing at each other, calling each other names- Chine actually almost stabbed Visor! On purpose! What a toxic relationship! Even more so than Black and Mutt!
Or is it? Underneath their hateful facade, they do care for each other. In another very weird but unhealthy way... That's it, everyone was going to try and help these two, as well find out more about what happened to them in the past, why they were what they were and maybe find a little love along the way.
You and your brother never asked to become the alternate universe Sans and Papyrus you both created. But by fuck was it difficult to keep things together like this, now the AU Sans and Papyruses were trying to get close. Stars above have mercy on their SOULs.

Summary
He had been having dreams of the same cute little drunk human for almost a year now. They were vivid and she was fun to talk to, and he was convinced that his 'dreams' were accidental manifestations of her magic. Magic she didn't even realize she had. But that magic may have just pulled her into a world of danger.
(not sure where I'm going with this but I love mafiafell sans. Lets see how this goes. Constructive criticism welcome. I'm a writing noob.)

Bewitched, Bothered, and Bewildered by CrimsonAndCloverOverAndOver
Fandoms: Undertale (Video Game), Mafiafell - Fandom
08 Jul 2025
Tags
Summary
Cherry Sweet is a rather unconventional performer at a club like 'The Velvet Crop' with her thick thighs and plush stomach, but she does well enough for herself. The patrons enjoy a bit of variety, but what will she do when she attracts the attention of a monster--and a mob boss monster at that?
Featuring a 1920's vibe with music from the 20's-60's, a meet-not-so-cute developing into a partnership, and a spitfire, plus-sized FMC. I hope you all enjoy!

Summary
In one multiverse, there is chaos.
A Creator unknowingly tips the balance, and a Destroyer writhes in pure pain.
The multiverse is governed by Fate and observed by Destiny, Karma, Light, Dark, Death, and Life.
But what no one realizes is—they are not the first.
Fate once created another multiverse… then abandoned it. Destiny, however, did not. Destiny gave it freedom and continued to watch over it.
When the Destroyer is cast into the Void and crashes into that forgotten multiverse, they take him in as their own.
And there, two beings—a skeleton and a human sorcerer—fall in love with him.

The Great Sans Undertale Roleplay Summary by Sharkrambles (orphan_account)
Fandoms: Undertale (Video Game)
29 Sep 2020
Tags
Summary
Ready for a wild ride into the depths of my middle school brain? This is a published version of a 50 page google doc I have written, complete with graphs and pictures. This beast of a doc is a complete recap of a nearly year long Sans Undertale AU roleplay I partook in nearly 5 whole years ago. It only went up to a certain point in real life but over quarantine I did some soul searching in old sketchbooks and abandoned word documents, along with finally revisiting the fandom itself and decided I would give this beast that lives in my head a proper ending so it may one day rest... Or will it be reborn into something new later? Who knows, not me thats for fucking sure.
Drama, murder, scandals, the mafia, cannibals, several illegitimate children, plot twists that make no sense, no rational choices, wars between fictional skeletons that are all technically the same person, and a sad ending? This has it all!
So please, take a seat, shut off your critical thinking skills, and be prepared to never feel peace again.
