    Summary

    Red’s brother has a way of always getting what he wants, and what he wants now is Stretch. No doubt Edge is going to make it happen, Red stands back and lets him work. But when it becomes clear that Stretch is replacing Red as the most important thing in Edge’s life, Red can’t help but feel a little put out.

    Sans, on the other hand, is missing his brother badly. Papyrus is away at school, leaving Sans alone and miserable. When he stops showing up to group gatherings despite his promise to Papyrus to always go, Red finds himself surprisingly concerned. Sans won’t respond to any of Red’s attempts at contacting him, so in frustration Red decides to go confront him. When he does, he finds out the dangerous secret Sans has been keeping and realizes it’s up to him to help.

    A story told in 100 words a day.

    Summary

    Sans’ machine brings alternate versions of himself and his brother to their universe in a one-in-a-million chance. Unfortunately, you get flung into the madness when your soul is used as a conduit for the machine. Your soul cannot take the strain, and it inevitably snaps. A month later, while Sans is testing the machine, the machine uses the power of all of the monster souls in the house to bring you to this universe. Trapped in a different universe with a broken soul, you attempt to keep your secrets bottled up. Little do you know; your skeletal roommates have many secrets of their own. Pulled away from everything you’ve ever known, unable to use magic, and your soul broken, you find yourself questioning if all of this will just keep getting worse.

    Summary

    Sans was so in his head that the resets would start back again, he didn't want to even try. Papyrus put in work to convince Sans that he needed to come to the surface with him, and not continue staying in the underground. Sans agreed to pick out a home with his brother, and began packing his things.

    With only a week left, Sans decided to try pulling his older brother back with the machine one last time, only to have to watch it sputter and stop.
    Sans gave up and packed his stuff, ready and moving out to stay with undyne until their new home was bought.
    His life and a few others really went out of whack because of the machines malfunction, with his sudden influx of brothers and the soulmate bonds that were slowly making themselfs known.

    Even after settling the chaos, shit still hits the fan every time he gets done untangling one mess.

    And the woman that is helping his strange family isn't making anything easier by making things easier!

    Summary

    The monsters are free from the underground, but they didn’t all make it. Papyrus, Sans younger brother is dead, leaving Sans to care for the two children he left behind. After a long night of work Sans finally relents and hires a nanny/housekeeper. Enter you, just another human down on her luck and running from her past. This job seemed like an easy way to pass the time and get paid until your past inevitably caught up to you. At least that’s what you thought, until you started developing feelings for the odd skeletons. Now you're having strange dreams, and all these new skeletons keep turning up.

    Can you help them? What is Sans hiding? And what is with this new gaggle of skeletons?

    hello, hey, hi Oki, so you know me by now. If ya haven't already I highly recommend reading Kamisori (Zombietale). even if the story and plots are completely different maybe you can get some sense of (a few) of the character's personalities.

    Zombietale is a really good fic! I love it!

    Summary

    After rediscovering a previous interest (Undertale) amidst a boring lockdown Aris invests more and more time into his hobbies. Covid being all done and dusted meant he had some time to indulge himself and so that's what he did.

    2 years later and he's chest-deep in the Undertale fandom once again and he's adding some final touches to a commission dedicated to said fandom.

    Who knew finishing art commission's could make you all woozy? As well as having the ability to transport you into a suspiciously familiar looking basement with an even more familiar hunk of metal in its residence.

    How strange?

    Summary

    [Y/N] [L/N] is a powerful mage with a bloodline well-known throughout the ages and her family have always been celebrated. They, however, despise how their bloodline trapped monsters beneath the ground. But, that is for another day. In not being able to afford basic accommodation for university, they had to rely on an old (and terrible) friend named Bethany. For some reason, most of Bethany's skeleton mates despise [Y/N] but why is that? Apart from the fact she is a mage?
    Just because she has a kindness soul, it doesn't mean she will stand for their bullshit.

    Summary

    Kinktober 2021 is here, and so are some horny skeleons!
    --
    the reader can be male, female or unspecified (based on the chapter you are reading of course) :D
    -
    There is absolutely no rape or dub-con, there may be con-noncon.
    --
    All the characters are based on my versions, such as the 'home for lost souls' boys or the 'a tyrant and an addict'. even the AU's that aren't in the canon story line of either of them, because this is a spin off series and not at all canon to my previous works.
    not only kinktober but also any short sexy time works i make as well.

    Summary

     

    The Guardian and Protector of Positivity, Dream, is a simple sort of spirit who just wants to keep people alive, safe and happy. When his brother and fellow Guardian, Nightmare, is corrupted by the magic of the Tree of Feelings, things begin to be a little more complicated. They are forced to flee the village they spent their entire lives in and learn that the world is far more immense than they ever could have imagined.

     

    When a kind (and vaguely suspicious) stranger opens their doors to them, the twins find themselves apart of something much bigger than themselves, a puppet show where everyone is trying to pull the strings.

     

    After all, the only thing that matters is that the audience is entertained.

    Summary

    You hid away from your family, from your responsibilities, from the whole world, in hopes that no one would come searching for you. But what to do when you are the Alpha and are bound to figure out all the shiz that is going on. Monsters are emerging from the underground. Hunters are starting to act strange. Strange disappearances in the forest. All the while, your personal space is being violated by the skeleton brothers.

    You look at the sky and sigh. “Well, shit.”

    (WARNING. This work is written by a not english speaker, and there might be many grammars fails, read with understanding.
    I'm starting to get tired of reading fanfics where the reader is a submissive puddle and allows everyone to do what they want. So here I am writing a fic, more to myself and my small whim.)

    Summary

    She was just trying to live out her life. Sure, she was alone on a mountain, trying to keep up with the ruins left by her entire civilization that would die out with her. But she was fine with that.

    Until a group of skeletons finds her.

    And why do they all look so similar?
