    Summary

    You were a dance teacher at a local studio, every now and then stopping by your favourite bakery to grab the daily sugary goodness your sweet tooth craved. You hadn't felt very connected with any one of your past boyfriends or partners, always feeling like something was missing...
    Until you walked into Muffet's one day and defended a skeleton monster from an asshole.
    Then suddenly, what was missing is now filled... And you only just met the guy.

    -Work in Progress-
    -Been working on this for a year and only now got the time to continue it, fuckin' hell-

    Summary

    There were flashes of memory from before. But when you wake up in a bed that isn’t your own, only to be greeted by a monster you’ve never met, you have no choice but to trust him. You feel as though he’s familiar in a way, that you’ve seen his face, or one like it... two, three times before? And there’s an itch in the back of your brain, like there’s something you left behind, someone even.

    This is the story of a human who came to be found by the Horrortale brothers, and nursed back to health after an “accident”. They can’t remember most of what happened before they were found in one of Papyrus’ many traps, and come to find solace in staying with the two skeleton monsters.

    This story takes place on the surface, in the normal timeline, but the skeletons have been brought together by means other than Sans’ machine.

    Summary

    You gently pushed the door and here you were, outside of the ruins. The first thing to hit you was the cold, then the realization that you just left the only safe place available to you. The second thing to hit you was that wow, maybe it would be warmer if you weren't wearing just some t-shirt and old jeans. The third thing and the last, was that now you were aware of holes in your sneakers. It felt like it was going to be a great day.

    Summary

    (Y/N) (L/N) was once an icon; an absolute icon to the masses. But destroyed out of jealousy, she is given a new chance with a brand new power and is thrown right smack dab in the pre-main plot of Undertale, where everything hasn't gone to shit yet from Frisk's meddling.

    And she'll be damned to let these poor souls rot beneath ground, not when she has the power to stop it.

    And dammit all, she WILL persevere and achieve her goal!

    ...

    Now if only she wasn't so damn attached to Flowey.

    Summary

    Sans is puzzled by one of the customers, who never speaks to him.

    It’s probably just a case of monsterphobia, though. Wouldn’t be the first time.

    Summary

    You're a simple girl. You live in a care facility for those with mental illnesses. Yours? You can't speak. Everytime you do, horror strikes and nothing good comes of it. You eventually accept your fate, until a skeleton appears and tell you he knows what's happening. You're speaking WingDings, and he knows someone who can help so he whisks you away to fix the problem. His house is absurdly huge and you're being doted on, well, until they find out what you did to be stuck speaking WingDings.

    You'll be (sorta) mute for the first ten chapters. I try to keep it interesting at least. Enjoy!

    Summary

    Marrying at twenty and divorcing at twenty-two doesn't exactly leave the best image of you. Adopting a seven-year-old child during the short length of your marriage only made that worse. Now, it's time for you to move on, though you find it hard to do so.

    It isn't until you come across a city bustling with human and monster folk alike that things begin to change, the change leading you to meet new faces – both kind and unkind.

    It's then that you realize that – sometimes – what you really need is a moment of repose. You find yourself in the need to simmer down and for your mind to clear as a consequence.

    You're able to find that place the further you spend time in your new home. There, you form brand new relationships with monsters you never thought could exist – one of them in particular making you relive things you once thought were long lost.

    A save point – as you chose to call it – was something both him and you were in need of.

    Summary

    You are a twenty-something university student, alone on Christmas because of your own choices and now the strange shape in your dreams is meeting up with your day-time hallucinations and trying to convince you that you've got just the dumb, bright red soul they need to open the underground? Sure, I guess that might as well happen.

     

    This fic is very self-indulgent, you're gonna have to suspend disbelief hardcore when we get into the thick of it. Will Update Quickly until I run out of prewritten chapters, and then slowly as I catch up. The whole plot has already been decided.

    Summary

    You don't trust most monsters, but you definitely trust Sans. He's sort of an ass, and a total perv, but he's also the only monster you've met that hasn't tried to kill you. You consider him a friend, but...let's face it, you'd fuck him if he asked. Too bad your SOUL already belongs to the King, and the rest of you belongs to the Royal Scientist.

    Low on plot, high on fluff and humor. Rated M due to foul language and suggestive themes. No smut.

    No set schedule; updates whenever.

    Summary

    You are a CNA and work hard almost every single day (heh rhyme) and yet you feel as though your life needs more, that you are missing something important.
    What could that be, certainly not a few weird monster encounters and skeleton neighbors who had moved in across the hall. No, not at all (Please notice the sarcasm in this sentence).

    ---------------------------------------------------------------------------------
    So, I have no idea what I am doing. Um, read if you want? I just wanna write fun stuff with skeleboyz? I kinda am doing this to improve my writing and hopefully whoever reads gives me feedback? Not a necessity tho. Uhhhhh fluffy times with skelebabez.

    Summary

    I don't know what I'm doing.

    This is my first ever fan fic of any kind.
    I'm sorry if my English skills lack completely. I'm dyslexic as hell.
    I'll add tags as I go, doing this on a mobile is horrendous.

    IM GOING TO BE HONEST, THIS FIRST CHAPTER CAN PROBABLY BE SKIPPED.
     

    We start our story with Sans. His point of view and the way of his new world above ground.
