    Summary

    Chaos: Self indulgent fluff and sin! I like me a good reverse harem fic, and what better than a reverse harem fic where one skele gets the other nine?

    Zion: This entire thing is just my gift to Chaos who wanted a skele only harem fic. If anything is questionable well, blame her xD the whole thing is just to indulge my partner.

    Summary

    Monster kind are now above-ground, you work hard, you don't think it's fair that a group of monsters are stuck in the same messed up world you were born in. But apparently fate is a cruel mistress because now monsters have to deal with the corruption of the surface.

    You are on the monsters side; but not everyone in your life agrees with your thinking.

    After three years of coming to the Undertale universe, living on the Surface and having 7 lovers, you would think most of the problems would have gone away already. But sometimes life is not that kind.

    Summary

    Something felt wrong being here.
    Watching the tiny beings scurry and bustle about in their pens,
    Some were lethargic while others just waited by the glass with a hopeful aura.

    The hope and wonder in their eyes felt out of place,
    The pressure began gnawing at my chest.
    I left the pet store empty handed that day.

    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

    It's been 3 long years since the war between humans and monsters occured. Monsters were feared after finding out what they were able to do and the power they could have over the humans, therefore lead to the unforgiving war. It started off as any other normal war could...bloodshed, attacks, strategy..that is until the humans tried to make a weapon. They thought making a new creature would scare off the monsters enough to leave them alone. They wanted to make living dead creatures, but...the experiment failed. Before they knew it, both monster and human lives were threatened by these undead creatures. Many people have lost their lives..but many are still fighting to keep their lives for as long as possible.

    Summary

    Hello Dearie,
    If you’ve found this note, you’ve probably found my friend with it. He’s been hurt a lot, and he isn’t getting better here. If you can’t help him, or if this isn’t your handwriting, please pass him on to the nearest Muffet. She’ll know what to do. Thank you so much, dearie, and I hope your life will go better than mine.
    Cordially,
    Muffet
    P.S. His name is Sans, and his favorite food is ketchup.

    Summary

    Welcome to the Fullhouse. Here's just an escape from reality. How far will one person run? What have you created and will the people you meet accept you the way you accept them? A soul made like this can only hold so much. You're losing your grip on reality. Whatever reality this is anyway.

    These characters are not here to have a good time, let's just say that.

    Summary

    Curry/Human Artie Oneshot

    Sans was excited. It had been some time since he had alone time with his little human, Artie. She was part of a polygamist relationship with him and his brother, and hadn't been able to spend too much time with her. Now that he can, he was going to show how much he loved her with a nice dinner. But things turn when she starts enjoying the meal way too much. Much to his delight.

    Summary

    Here are some side stories from A Skeleton Pride Parade!

    These are mostly for times that I came up with an idea that has not yet or will not fit into the main plot of the story. Some of these may be cannon to the plot, some may not—and some may show up later in the actual story. If you haven't read the main story yet, I would certainly encourage you to do so!
