Hiya, it's me, everyone's favorite (not really) author, sighnerd, and welcome to my oneshot book, where I will make literally (almost) anything, ranging from X Readers, to ships, even goofy little shenanigans like a stupid, chaotic road trip with the Sanses :D

You can also request oneshots! Though, there are some things that I won't accept, like:
Cross x Dream
Dust x Swap
Horror x Lust
Killer x Nightmare
Dream x Nightmare
Fontcest (basically any Sans x any Papyrus, even UT!Sans x UF!Papyrus)
I don't accept those because they make me uncomfy, and if you request something that isn't on that list but still might make me uncomfy, I have a right to decline.
Also please don't rush me to finish your request! I get stressed when people rush me, but a friendly reminder if it's been a while (like a month), saying something like "hey, in case you forgot, i requested [request here] a while ago, just wanted to remind you" because most likely, I forgot about it :p I don't have good memory sometimes, but I'm trying my best!

THIS IS A REMAKE OF MY FIRST ONESHOT BOOK WHICH WAS SADLY DELETED D: THE ANNIVERSARY FOR MY FIRST ONESHOT IS MARCH 7TH :D

Byeee!

Her Guardian || Demon! Dream Sans x Reader, de StrawberryMilkSnake

When a demon summoning goes wrong, a rich and powerful man's son gets killed and (Y/n) is forced to team up with the Demon King that did it to survive the ensuing attempts on her life. | Set in the same demonic skeleton universe as my demon Nightmare book with a different story, it's my take on the simple question: ''What if (Y/n) summoned Dream instead of Nightmare?'' | - Demon! Dream Sans x Female Reader - Alternate Timeline of ''His Summoner || Demon! Nightmare x Reader'' (but you don't need to read HS in order to understand Her Guardian!) - Dream has his own version of denial so it'll be a slow-ish burn again - Honestly you could read this with no prior knowledge of any of the characters and you'd be just fine - It'll be a reverse harem again (kinda), and I'll throw in some bonus chapters with the other Sanses for extra (non-canon) fluff that doubles as a breather from the story - Some characters get some much needed therapy (*cough* Dream) as well as more trauma✨(I don't eff around, and to prove it, characters will die) - A lot of the symbolism and hidden meanings aren't obvious, so you might have to be on the lookout to see them (though I think I was a little more blunt this time around?) - It's my interpretation of the characters (kept as canon as possible)

PLEASE READ BEFORE GETTING INTO THE STORY Description: Your name is (Y/n) and you are originally from an au called Dreamtale! Your life hadn't been the easiest however, but you were quick to always move forward despite this... Before Nightmare had become corrupted, you were his best friend and lover. You kept him from his breaking point, you maintained his sanity and most importantly... returned his love. One thing that is definitely important about yourself is that you are a selective mute... And your only desired partner for conversation is the King of Negativity himself... But what will happen once the true evil lurking within your lover drowns out whatever light he had left? What will happen when you discover that the Nightmare you knew was replaced by a monster that still somehow holds love for you? "And even with the evil finally in control of Nightmare, if both his sinister side and his old self agreed on something- then it would always be his priority... They both love her." This is practically my first story that I have ever decided to share online. It is quite a terrifying experience for me, so I hope that anyone who decides to read this will enjoy it. Anyway, I should probably inform my readers about a few things. First off, my primary language is not English, however, I will still be making an effort with my grammar! Second off, I will try and update this as frequently as possible... Even though I can get somewhat shy or concerned about how my work goes. Otherwise, all you will need to know is this: (Y/n): Your name (F/n): Friend name (E/c): Eye color (H/l): Hair Length (H/c): Hair color (S/c): Skin color (F/c): Favorite color Some things I will likely determine for the reader, but what is posted above will be the basics. Please also note that this story may contain some content that would be best for more mature audiences. Also, the cover image belongs to me, please do not use it without permission or steal it.
