[Underswap Papyrus x reader]You have a secret. You are the last of your kind, shapeshifter / Human hybrid. The very culmination of your being constantly pleads for you to be honest about who you are, but your kinds law prevents you from doing so. Will you be honest and open about your powers with your new friends, or will you continue to lie and hide in the dark? (Yes the title is a pun, if you aren't aware bonafide means honest/ trustworthy, yes the title contradicts itself it's supposed to show the struggle between logic and emotion.)…

*Knowing that Author frequently updates this book...fills you with DETERMINATION.This book is no longer continuing and was closed January 6th, 2017. Are you looking for some fluff? Looking for some Undertale? Maybe for some X Readers? Well, you're in luck. Because this book is full of it! Thank you all for so much support and so many views! I wish I could hug all of you! (Undertale was made by Toby Fox. I do not take credit for any of these characters.)(If you request something while requests are closed OR on the WRONG CHAPTER I will not do it. Thank you.)…

yup. it's another one-shot book.also please note that the first stories are not my finest. I've tried fine-tuning them, but it's not going great. So humor me and keep reading, lovelies.note: obviously Undertale is not mine and neither are any of the au's. I'm not that cool. again note: this is my personal interpretation of these characters, and it may or may not be the same as yours. if you have a problem with the content feel free to contact me but if it's a "x wouldn't say/do that" please know that this is what I see them doing. if it's something offensive that's fine but if not, then whatever.(P. S. I will gladly take requests cuz I feel awkward picking them out of the blue) (P.P.S. I cuss so if you get angry about that then that's no bueno)…

Firstly, this is something I wrote back in 2017 or so, so don't expect too much out of it, I just thought I'd post it, mostly so everyone can see what a bad writer and a nerd I was, and I've made many stories since this, I'm just not sure if I'm ready to post them yet. But, yeah, here's an old, cringy, fluffy book of oneshots, and hopefully you can find some enjoyment out of it, despite how old it is.…

It's the monsters first Holloween. Of course being tall and lanky, Papyrus HAS to dress as the Pumpkin King, but to actually be mistaken as him- it will be quite the spooky journey back to his bro and the others.Idea made for PanteraPlayzGatchaYT…
