This is a collection of short stories featuring the Blueberry version of Underswap Sans! Sanscest is allowed along with fluff, angst in some cases, and probably smut. Blue is only a bottom in this book, however, so please don't request any one-shots where he's a switch.
Blueberry Sans is owned by the fandom as an alteration of Swap Sans.

Nightberry Oneshots!
Art cover and other art isn't mine! I'll be doing oneshots. I'll do anything but r@pe, !nc3st, and things related. Note: AFTER "THE RUNAWAY", THERE WILL BE NO MORE FEMALE BLUE. EXTRA NOTE: If you ever come on here just to ask why I won't make female Blue, you're getting blocked. I have my reasons for my decisions, and I refuse to change his gender. Also, please no longer ask for part 2's. It's called a ONE shot book for a reason 🥀. #1 in Bluemare on 9/10/25 #4 in Nightberry on 9/20/25 #5 in Sanscest on 9/18/25 #6 in Underswap on 7/12/25 #8 in Bluemoon on 9/10/25 #9 in Dreamtale on 8/28/25 #11 in Nightmare on 9/10/25

The King's Queen (Nightmare Sans x Reader)
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.Complete![Sanscest Oneshots [DISCONTINUED]](https://img.wattpad.com/cover/246512651-256-k355464.jpg)
Sanscest Oneshots [DISCONTINUED]
[WARNING: Some stories will have Cursing] Please don't expect it to be the best. I'm still working on rewriting a few of the short chapters. I'm planning on doing more ships, as well as experimenting with other ships as a multi shipper would. Btw, cover not mine. I found fan art for errorink and it just happens to be a favorite of mine. This is my first fanfiction book ever. PS: When requesting, your request may take up to a few days or maybe a week, depending on what time you request something, as I of course have other things to do that keep me busy for awhile.Complete
