    Summary

    Monsters have been freed from the underground, and honestly, you don't really think they should have. You wouldn't consider yourself 'racist', you just fear for your own safety when murderers wander the streets and move in next door.
    So spilling coffee all over a very large and intimidating skeleton monster was probably not your best move ever. But instead of gutting you, he offers to buy you another coffee. And, despite his... 'crude' language, he seems to be a nice guy. Maybe monsters aren't so bad after all?
    But why do the monsters who used to pay you no mind now cast you pitying looks and avoid you all together?

    Summary

    The barrier had been destroyed, monsters set free from their century-long prison. They had freedom at long last, and yet Monsterkind was slow to accept this truth. The idea of freedom after so long was almost surreal- But there were still the few monsters that wanted to go, to see just what their beautiful world came to become. After a long discussion between the great king, accompanied by his great advisor, and the officials of the cities closest to the great mountain that hid the monsters away, Monsterkind was given the opportunity to grow under the warm sun, within the safety of foster homes.
    But that is not all- The barrier dropping released concentrated magic back into the world. For those humans who descended from monsters, it poses an interesting problem when long dormant magical genes and cells are reactivated violently. Humans and monsters really aren't all that different.

    Summary

    It's you and the Edge™ Sans. You make love.
    A lot of forbidden loveful fluff mixed with explicit pornography and the fear of getting mauled to death by a bunch of bloodthirsty monsters.
    Reader has a vagina, no defined pronouns are used.

    This is part 7 of an alternate version of our long going skelebros polyamory series and has some sort of continuity going on, for the rest of this series as well as the original one either click the link under the tags or look into my archive.

    Check out our Tumblr blog for progress updates and silly art - bonefucker-sanstasies.tumblr.com

    This work might contain brotherly bickering, the threat of deadly capitalism and other Edgy™ themes so look out for that, friends

    Summary

    you jumped into the underground, made your way through the ruins, and then you met sans. he likes what he sees and decides he's gonna keep you around for his own amusement. He's a nasty lil skeleton who never fails to remind you that he owns your ass and you kinda like it, but you also really don't. Consent as well as whether you like him or not is kinda a blurred, greyish area. Nevertheless, shenanigans and angsty love feels ensue

     

    Basically this will be shamelessly smutty and kinda twisted with nihilistic ideologies, dark humor and a fucked up lack of morals because I like that shit.

    Summary

    When everything started to fall apart in your life, you were too young to do anything.
    Many years later you grew tired of trying to fix everything. Every person that walked into your life by now only tried to hurt you or got hurt. You wanted to end everything.
    So what's the holdup then...?
    Well, a certain skeleton named Sans walked into your life. And he refused to give up on you.

    Summary

    Getting a chastity key from a parent is one of the hardest challenges a suitor faces. Not only do you have to win the heart of the girl, you have to win the heart of her parents. In the end, a suitor spends more time impressing the parents than with the maiden. Winning the key is akin to winning her innocence. If the parents give you her key, they're giving you their daughter for all of time.

    If winning the chastity key of a peasant is hard, it is infinitely more so to win the chastity key of the Princess.

    or basically, nanny papyrus ruins the innocence of princess sans.

    **This can be taken the wrong way and can be read as pedophilia. I realized that while proofreading it. Please understand it is not meant to be taken that way. If that makes you uncomfortable, either don't read or skip to the break in the story**

    Summary

    This takes place in a post Underfell King Papyrus ending.

    Struck by under population, King Papyrus makes it law that all monsters, that were left alive by the murderous little human, had to procreate. This leaves Sans and the king in a tight spot, there are no female skeletons and both skeletons are sure they are the last of their kind. Fell!Sans proposes something, with the help of the first Royal Scientists machine to travel other universes, he will find mates for breeding purposes.

    Tale!Sans is having his first sub heat as a female, this happens when there is only males and the strongest one undergoes a gender swap. He knows this means that Papyrus would have to be his mate, that won´t do, they are brothers for the Angel´s sake! So he does what he does best, HE RUNS.

    Red and Sans are roommates, and they're so similar that they tend to drive each other completely insane. So guess who works out a deal?

    Summary

    Sans is in trouble. There are going to be a lot of hypnotic or tentacle sex themes in this. This is going to also be a lot of rape. Also I do chapters on my own, but please suggest pairings! Any AU Sans x Original! Sans! I can do more than one chapter and theme for any pairing. My favorite is---

    Dust! Sans x Sans...

    Summary

    You had to hand it to the plant. Although you didn’t trust him, you definitely didn’t trust the ragged goat lady even more and once you mentioned him as he suggested, she left you in her house alone, when you promised to go to sleep in the kid-sized bed you barely fit into. Once you were sure she left, you took a chance on the directions the flower, Flowey, gave you. And now you were here, trying to make sure the dead stayed dead because hell had apparently frozen over.
