If you break my heart I'll die
So be sure that it's true when you say I love you
It's a sin to tell a lieA collection of drabbles about nsfwshamecave’s Underlust AU, featuring Romeo (Underlust Papyrus) and Benvolio/Benny (Underlust Sans). Exploring personalities, headcanons, and a little worldbuilding to the melodious, bittersweet love ballads of traditional pop, easy listening, and more.
(Despite the source material, these actually won’t have any smut or anything too explicit- some suggestive content and swearing/vulgarities tho! Ie. Not NSFW but viewer discretion is advised)

Summary
You watched him unwrap his lunch, pouting.
“C’mon, man. Not even a bite?” He started eating and you groaned dramatically. “I’m starving. I’m dying right in front of you. You’re killing me, Papyrus.”
“good,” he muttered around a mouthful of food.
“Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.
“because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know i only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”
You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”
“so, never?”
“I’ll try.”
Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”
You beamed, soaking up the affection. Papyrus always had your back.
But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.

Summary
Over a millennium ago, monsters and humans went to war. As the bulk of monsters were sealed in the underground, some monsters stayed behind, continuing to fight for their brethren. As time warred on, a treaty was formed, calling the end to the war between the humans and monsters remaining on the surface.
Years later, the barrier sealing the underground is destroyed. Surface monsters, now fully integrated into society, take interest in finding their long-lost kin. A skeleton monster, in love with the idea of finding her soulmate, travels to the city in search of the last of her kind. And you, her best friend?
Well, you’re along for the shitshow.

Summary
Just a bunch of Sans x Sans one-shots. Read the warnings before chapters, most chapters aren’t for everyone. These include a range from fluff, to angst, to smut, to rape/non-con. These are labeled accordingly and accurately. I mostly write what I want, but I do accept suggestions and might do one from time to time!
Yes I know most of these chapters include Nightmare Sans.
If you don’t like it, don’t read it, the warnings before chapters will state directly what’s in said chapter, these aren’t for everyone.⚠️IMPORTANT NOTICE/TRIGGER WARNINGS⚠️
I don't condone any of the actions in this book nor encourage or suggest them. Trigger warnings are provided at the beginning of every chapter, please read them and decide the best course of action for yourself based on how you think you’ll react. You do not have to read anything you don’t like for any reason.
In case you missed it in the tags: DEAD DOVE: DO NOT EAT, and potentially disturbing and triggering content ahead.

Summary
Deep into the city Ebott, just past the entrance trails to the mountain, there is an abandoned house. Though, is it abandon, or just gave up on?
Most locals of Ebott know of the three-story home with a beautiful Victorian build. The gardens that seem to remain in a constant state of perfection, the vines that creep up walls and through the one broken window out front- said to have been broken during what led to the haunting… Ebott’s very own haunted house.
That’s where you come in, SPIRIT, you are the haunter of Ebott’s spooky stories and the original crypted before monsters broke to the surface.
( based of my {monster?} sona, spirit. but this is an /reader. you don't remember your name or life, so you are just called Spirit. )

Summary
Silly summary: Lust and Red play 7 minutes in heaven at a party. Except...it isn't 7 minutes, there was no pulling names out of a hat at random, and Lust is disassociating. Fun times ensue!
Not so silly summary: Lust is an outcast, ostracized by most monsters outside of his AU with very few exceptions, and even those exceptions were those that Lust never really considered his friends. One day he gets an invitation to a party, curtesy of Blue, so of course Lust makes his appearance. At the party, Lust finds none other than Red, a monster that though he finds him attractive, the Fell monster was a constant bully and instigator in his life since venturing out into the multiverse. Why Red does this to him? He'll have to learn the hard way.

lust needs friends- any friends! also ice.
red is an asshole, but he gets around to being the friend in the end.
