    Summary

    In a world were monsters are forced into slavery and are controlled by collars around their neck, you never thought you'd be a part of the twisted reality. Your sick and owning a monster was the only way to keep you alive just that little bit longer. You hate the idea, Your Dad hates the idea, but it is the reality you know have to live with. It does help a bit to know that the monster your stuck with hates the human race and has no qualms about you dying. You do wish he'd stop spoiling your TV shows but it's not like your going to order him not to.

    Summary

    A storm scares the crap out of you one night after a loud strike of thunder. Lucky for you, your five wonderful bonefriends are ready and willing to stay with you until it passes, for your sake of course. No way a little thunder would freak them out, heh.

    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.

    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

    An AU based on 'The Village', Rus knows he shouldn't be in the woods.

    (If you've never seen The Village, I think it would be enough to know that the villagers live in an isolated community surrounded by a forest. The woods are forbidden as Monsters are rumored to live in it and any shade of the color red is forbidden as it supposedly attracts them. Thus, Rus shouldn't be in the woods, but the forbidden can be oh, so attractive, can't it.)

    Summary

    Stella Bennett has always been the one in the spotlight. Afterall, who wouldn't want to know her?
    She was unnaturally pretty, with long golden locks and rare but beautiful jade green eyes, and never bragged about it. Amazing singer, flawless dancer, talented cheerleader, a fantastic person. She seems so sweet and humble...

    But that isn't how I see it. I know that pretty face hides a manipulative and dangerous woman who only does things to get what she wants, and she DOES get what she wants.

    I gave up a long time ago trying to tell others that. No one believes the mousey little sister Riley, the pudgy nerd who sits alone in the library. People laugh when they see me. That girl, sister to Stella? Poor Stella, it must be awful having THAT as a younger sister.

    Both Stella and I are out of high school now. Stella is an up and coming singer and social media star living with 8 rich monster boyfriends, and me, juggling online college and my job as a librarian in a tiny cramped apartment with my fat little dog named Bean. Even though I’m struggling to stay a float, anything is better than living with my sister and her harem.

    But I never get what I want, do I?
