    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

    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

    (Y/n), a high ranking Platoon Commander in the Military, was on a mission with her squad when her plane was shot down by an enemy ship, leaving her stranded on an unknown island, with none of her comrades in sight.

    It would have been all fine an' dandy... if she wasn't surrounded by three Alpha Skeletons and one Omega Skeleton. All of which want to fuck or be fucked by her.

    So now here she is, having to assess her dominance as an “Alpha” to get by with her limbs still attached and her clothes still in one piece. Even if one of them looks like he came straight from Satan's asshole.

    Summary

    Error couldn't hold it anymore, he no longer bears to tolerate the tremendous amount of pain he receives everyday.
    He wanted-no needed to just let it all out, he does not want to play these games anymore. He wants it to end, he just want something good to happen for once in his miserably torturous life.

    Why is that moment going to change his life?

    Stay tuned to find out

    Summary

    It's been a few years since you narrowly escaped the clutches of the Fell brothers and left home to start a new life with your friends, Axe and Sugar. After everything that happened, you've sworn off love, and anyone who's shown interest in you has only aroused your suspicion.
    Putting that aside, things have been pretty good - you have a steady job at Grillby's, the farm you live on brings in a little extra money, and Sugar has found his calling restoring or up-cycling furniture. You're financially and emotionally stable, can't even remember the last time you were in any danger, and have a great relationship with your beloved skeletons housemates.
    Yup, life is pretty good - you couldn't want for anything else!
    Or so you think, until Sugar's shameless flirt of a boss makes you realise something you wish you hadn't. Something which may just destroy this happy home of yours for good.
    Love? Oh God, not again...

    This work is a sequel to Love? I Think Not, and it's highly recommended that you read that one first!

    Summary

    The war between humans and monsters has been raging for as long as Grillby can remember - which isn't saying much. He was summoned to fight in it after all. As crazy as war is however, it gets a little bit crazier when he meets a certain prodgious skeleton by the name of Gaster. The friendship is rocky, their surroundings even rockier. And a whole knew wrench is thrown in the works when a human emerges with enough control of their Determination to meddle with time.

    (This fic expands on my Wartime headcanon for Grillby in a previous fic I've written called "Phantom Pains". You definitely don't need to read that one first to understand this one. They are companions, and can function as individual pieces. But if you wanted to know more of my thoughts on the wartime Grillby stuff I touched on there, this is where you'll find it!)
