    Summary

    You're from the Horrortale universe.

    A universe where everyone has suffered-including your favourite skeleton brothers.

    You were merely 15 when you fell to the underground-a lot has changed in the four years you've been there. Somehow, along the way, you'd convinced the butcher himself to not slice you into mince meat, and even moved in with them at some point. Nowadays, you spend your time struggling to survive WITH the skeletons, rather than against them (thank god).
    Though things are about to take a drastic turn. You thought one pair of skeletons was strange enough- try 8 for size.

    Summary

    Once upon a time Humans and Monsters went to war.
    Once upon a more recent time Papyrus' brother Sans got a promotion. And now Papyrus was off to buy him a human toy, pet, simple plaything to fuck and to kill...
    Humans and Monsters. That was all that was important. Humans and Monsters. Just supposed to be a week of fun. One's hell being another's heaven. Humans and Monsters. It's just the way things go. Her hell, their heaven.
    ....... but something's wrong.
    It's not the way it goes at all.
    And you may think the worse person can't change because LOVE and hurting are a cycle and the more you hurt the easier it is to hurt.
    But in the end, hope and Mercy are too.
    You just have to keep finding ways to stay determined.
    Even when it seems impossible and hard, and Mercy apparently seems spent.

    Summary

    You find a room going for cheap in the mountains. It sounds too good to be true, but there's a catch. 10 of them, that you're told about, at least. How will you go, living with a bunch of eccentric skeletons.

    A reverse harem reader insert story, that will feature a variety of tropes. And Skeletons.

    Summary

    You saved everyone.
    You made the right choices.
    You've made some wrong choices.
    And you've made choices that you're still not sure about.

    Welcome...to the second part of diamonds and dust (gold and rust), which I now unofficially dub, "the squeakquel," of my series.

    I was looking directly into Death's face, and he had a fire in his eyes.
    I shut my eyes. The face I had once hated seemed to melt into a foggy nightmare. When I opened my eyes again, I saw the face of of Reaper....
    And it was weeping.

    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

    You're best friends with a pair of skeleton brothers for nearly a year now! 5 months if we're being literal in how much you've conversed and hanged out with them. 8 months if we're just talking about Papyrus. He's the best.

    And something popped up that might very well threaten their friendship with you and their relationship with their cousins and relatives.
    Especially with their new house mates.
    Sans 'Buffet' Luu and Papyrus 'Kyle' Luu.

    You are so not happy.
    What a way to start the first year of University.

    Summary

    Agreeing to go on a blind date was a bad idea from the start. You have no interest in a relationship, no matter how "perfect" you and Papyrus would be together.

    At least Papyrus agrees with you on this.

    Too bad literally everyone else you meet is convinced the two of you are dating.

    Summary

    "Hello... everyone in the Multiverse.

    You've kinda caught me in a compromised position here so....

    My name is Ava.

    You don't know me but...I am your stalker.

    I spy on everyone.... In every universe.... To the extent that I've witnessed your entire lives and countless possible timelines.

    ...as far as first impressions go.... this destroyed city you see behind me...

    It was totally like this when I got here....

    Also, I understand that some people may feel uncomfortable... Even a little murdery...

    .... And I promise, the day I get tired of abusing your privacy for my own entertainment, I'll quit and go get a real life.

    But until that day... Yeah... I'll know when you're sleeping, when you're awake.... and also, I'll be criticising your technique in bed.

    I have scoreboards ladies and gentlemen."
