    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

    “Well, fuck you Ink.” You hissed, narrowing your eyes and barely controlling your desire of shattering the polished rock against the floor to liberate your anger.

    You were the player, you were the author; You were also Dust, from your own AU. But it seemed that you were trapped in his human form. Which, unfair. Because although you were human it feels icky to have skin covering your bones.

    It was obvious that you were more Dust than Y/N.

    Summary

    (Y/n) lost her job, which sucks. If only she hadn't lost her second job, and apartment, as well! Now all she's got is a camper full of her crap on the back of her truck, and nowhere to go. At least she found this campground, even if it is in the middle of nowhere, and looks like no one has been around it for a while, and a skeleton with a head wound tries to make her into a meal... Rough start to making new friends, but his brother is sweet enough!
    And then there's the other skeletons who inhabit the other cabins, who all look vaguely similar... Their explanation of "cousins" only goes so far, but there are more concerning things to worry about, like how almost every skeleton is trying to get into her pants, their heats, and where her clothes, particularly her socks, keep disappearing to?!

    Summary

    You just started your last year of college and you need a job. Badly.
    When a wanted ad online leads you to the forests surrounding Mt. Ebott, to a giant, brick house full of monsters, you wonder if this might be worth it. Some of these monsters seem alright; friendly, even.
    Others - downright terrifying.
    ...but you really need this job.

    Summary

    While looking up some World of Warcraft things I came across the information that the Shadow mage is the preferred companion of the Void Walker. Naturally I instantly thought of Sans.

    And who is my favourite Sans?

    Why Red of course!

    So this is my attempt at a shamelessly self indulgent one shot!

    This is not a harem fic!

    Summary

    The M.A.G.E Project was not considered something you sign up for if everything in life is going great. M.A.G.E Project stood for the Monster Assimilation (and) Genetic Examination Project. The government were trying to integrate monsters, who had only emerged from Mt Ebott a few months ago, into human society but due to their apparently violent nature and their ability to use magic no one was sure if it was safe for them to be around humans. So a test was proposed. For a full year, willing human and monster participants would live in an enclosed society together to not only test if the two species could live together but to also see if magic had any lasting effects on the human participants. Your life wasn't really great so deciding fuck it you sign up to room with two such monsters for the year. Only with your server anxiety and mild depression living with strangers is a lot harder than you first thought it be. The only thing that could possible make it worse is if you found your soulmate while on the experiment.

    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.
