    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

    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

    Just a bunch of Sans x Sans oneshots. These are not for people who don't like them. They have rape, fluff, angst, lemons, etc. If you don't like it, don't read it.

    I don't condone any of the actions in this book nor encourage or suggest them.

    I'm NightKiller0185 on Wattpad. My book is pretty much called the same thing.

    Summary

    Literally…

    Do note that Error is bottom as default because I have a Bottom!Error diet.
    It's kinktober and this is my first trial of the event. Each chapter, or in this case, ‘day’ is different from one another unless told otherwise.
    - - -
    (AUs or characters don't belong to me unless I said so. Undertale belongs to the one and only Toby Fox, and it's AUs belong to their wonderful creators out there. I only own the story and the plot. The characters' characteristics will change and be altered for the sake of each and every story.)

    PS. Tags will be updated as I go along the Kinktober Prompt list.
