    Summary

    Reader leaves home to chill down a little and she falls into the Underground. Sans is there, ready to meet the anomaly of the timeline, but he feels like his soul is calling for her. He knows there's something wrong. Where is Frisk? Why is (Y/N) there instead? Why did she fall so late? Why can't he get the fog out of his skull and remember?
    He needs someone he can cling to. But he can't let himself. Not yet. You'll help him and the entire Underground lead to a fair life on the surface. You'll make sure of it. And you'll lend Sans your shoulder. You'll slowly convince him he can lean on you, past his shell.
    The only problem is... what is he hiding from you?

    Man I'm sorry this was an awful summary idk how to do this

    Summary

    Nightmare isn’t used to asking for help, it’s not like he’s ever received it when he had asked; but his crew is hurting and dying, and when backed into a corner he’ll do whatever it takes.

    Sans and his mages haven’t really signed up for this crap, until they do.

    Summary

    Go on vacation, they said!
    You need to relax a bit more in a nice place, they have said so politely!
    Visit an exotic place, they said!
    Nothing can go wrong in a ship, they said totally convinced!
    You need to meet someone nice and start a relationship, they said worriedly!
    And you have listened to them over and over again… Why did you listen to them?
    WHY?
    Someone, any kind of deity… could somebody tell you just WHY is this happening to you?

    Why are you lost in what seems like an island lost from the hand of man in the middle of nowhere with weird creatures that seems like monsters that are trying to court you in the most ridiculous ways possible… and why must all of them be fucking skeletons!!!

    And why, oh god WHY do you think they’re HOT beauties out of nowhere?
    Are you really that lonely or is this island somehow messing up with your mind?

    Summary

    Getting the craziest one off my chest going to be making a one-shot book similar to the one for 'Poison Apples in the Garden'. This is as close to non-con as you dirty sinners are gonna get so enjoy it! As for this whole thing canonically I'll let you decide that 7u7 the only thing I can say is up to the dinner scene the fact Moon did kill a bunch of party goers is true it is what led to her being taken out of Underswap!

    Anywho enjoy this smut you filthy awesome readers, and lemme hear your thoughts~ Next will be Error.

    Summary

    At the bottom of the porch stairs, propped against the railing, Dream glared somberly at the boxes as he finished off the tea that Ink had brought him earlier that day. It would probably take him two trips to get them up the stairs, but once he was done, he was done. He could start unpacking in the morning, and start new.

    “you lost?”

    Summary

    Just one of your generic ABO Island fic, with a bit of a twist of a female skeleton who's tall than all the Sanses yet smaller than all the Papyruses.

    Summary

    It was a nightmare for you before you finally left the mansion. Heather had them all wrapped around her finger and made your life hell. At least you finally got away.

    Then three years later you see on the news- the mansion was used for monster trafficking. The darker parts of society in other countries were always looking to get their hands on a monster to study.

    With the autonomy Sans was afforded by monster society, royal guards and police never suspected the mansion was where monsters were being kept imprisoned after being kidnapped. A bloody and violent escape attempt finally exposed the secret. Now all the monsters imprisoned are free, including the skeletons who were chained for two years.
    You want nothing to do with it, but there was one skeleton you did care for- Mutt. His brother was dead and who knew what traumas he faced in the mansion. He helped you get on your feet when you left. He was there when you needed him and it was time to return the favor, regardless of who else you might meet...

    Summary

         Y/n was having a nice day walking down the sidewalk. She had just gotten off with work and had exited the office wearing her coat since it was a chilly fall.  “Hey Y/n!” Macy y/n’s coworker waved running to catch up to y/n. “Would you wanna go get chicken wonton tacos? I want to introduce you to my fiance Travis.” She said pointing to a boy near her. “ Oh hello” They stood there talking for a while. Suddenly a scream rang out a man in a dark coat rushed forward with a knife down the street. Heading straight for Macy. Y/n always the quick thinker pushed macy out of the way and ended up taking the knife to the gut. Y/n fell over. Blood started to pour from the wound. y/n gasped she could hear people screaming “someone call 911!”  However in the end y/n succumbed to her injuries on the spot. You died and that should be the end right? Well monsters come back and a new beginning starts hopefully new relationships start to bloom too as you get used to your new skeleton body and magic.
    For anyone new this is a voter fic. So you comment on the newest chapters to influence the story.
    I'm back to updating consistently :) 2-3 times a week/once a week if bad week

    Summary

    I'm making a new book for the smuts because I don't really like the old one. It just feels weird to me, if that makes any sense?

    The ships I write smuts for are mostly gonna be ones I personally ship, such as; Errorink, Outerberry, Cream, Killermare, etc. I know what tag is in the Additional Tags. I know what tag there is. I'm not gonna write a lot of Dreammare, but I know at some point I'm gonna write Dreammare. And I hate it.

    The first part is gonna be a bit of a request page. Read that for more details if you want to request a pairing.

    Summary

    Error was used to a certain type of crowd at the cafe. The hopeless writers trying to create the next bestseller, the students desperately whittling away at their assignments, or even the broke folks using the free WiFi to download movies or check their depressingly dull social media.

    But never, in Error's few years frequenting the cafe, had he ever seen a character quite like the newest regular.
