Just a heads up not the greatest at creating stories. Anyway you'll be a different reader each time but with a different Sans. I won't upload much but I'll try to upload as much as I can. Warning: there will be smut, kissing, maybe some sexual content, swearing, anything traumatic like abuse, and you being a hybrid reader like a Neko. Also none of the art is mine, all credit of art goes to the artists. So try and enjoy my terrible writing. 😄

Between Stars And Shadows ~Evil Sanses x F! Reader
My first Fan-Fiction! Will try to keep character's personalities as close to canon as possible, slow-burn, and full of angst, and fluff. However this will also contain some violent and triggering themes, if you are easily triggered do not read, how ever I will add warnings when necessary so you can easily avoid them. I do not own these characters or any artwork shown in this story unless told otherwise, all credits go to their respective creators!
Home (bad sanses x child reader)
You were an average kid, somewhat having a older mind than most of your classmates. you had always been into the undertale fandom, and even knew almost everything about the aus and soul colors. while what seemed like a normal day at school quickly turned around after a huge bang struck the class room next door. in this story y/n is nonbinary and 12-16 years old. But more interpreted as 14 I post a new chapter every 3 day and 5 days at the maximum. WARNING: this story will mention some forms of slight emotional harm. And Sexual abuse. Readers be safe. Please if you are in any danger, contact someone. You are not alone. With that aside enjoy the story . This story is finished as of September 1 2022, I encourage you to read my other story "Our Disturbing Love" And in the next month or couple weeks I plan on creating another bad sanses x reader.Complete
Sanscest Oneshots Fluff & Smut
Most of these will be fairly short and a lot of these will be fluff because I'm new to writing smut and it makes me nervous. If you have any requests please share!

Sansmate, Vol 1: Ain't nothing like the Wicked
A collection of Soulmate AUs, starring YOU and the 'Evil' Sanses. Prologue sets the stage, and then it's on! Warnings ahead for violence, gore, disturbing reads and lemons....can't have a soulmate without some smut...the letters are literally there. Prologue also introduces the closest I will ever come to inserting myself as Author into a story. Hope y'all like Paradoxical. No 'Evil' Sans shall be repeated, and even you as the soulmate character might change personality-wise to suit the AU. NONE OF THE ARTWORK OR SANS CHARACTERS OR AUS ARE MINE! I just write these little shorts.....I suck at drawing.Complete
I'm a Sans ( au sans x reader x au papyrus )
This isn't a typical sans x reader(now papyrus x reader too). It's got more than that, well at least a different plot device first chapters will be about, just you(but it'll be good, I think so)and it's about you dear reader, you are now reborn as a Sans of a different au, but you don't have time to marvel how you're been reborn as your favorite character, because if you want to live you better focus because unlike frisk you're not coming back a second time when you die. (Short, and I mean short chapter, but this will ensure I can post more -w-) (Edit: this is context of your previous life is that you are originally female, aged 15, you had died during a car accident, you were sleeping in the back of the car, while you had a road trip to visit your family in Canada. The car had driven off the road because of black ice your father did not see in the dark of night. You heard the sound of your fathers scream then lead by your mothers then little brother's scream. You banged your head in the chair in front of you making you pass out, and when you open your eyes you had found yourself be popped out, but you didn't know that at the time. Art always be done by me. Edit: discontinuedComplete
Capture & befriend (one-shot sanscent)
Mostly about Moonsky sans by https://x.com/moonsans123 and the bad sanses, and ships so :/ This story will contain alcohol, smoking, drug use, swaring, abuse, misspelled grammar and, violence, very detailed descriptions, kidnapping, LBTQR, Lemon, lime, fluff, angst, masking autism, panic attacks, mental illnesses, self-harm, PTSD, experimentation, and very uncafterble topics, TW Rape, and thoughts of suicide, and ships you may feel uncafterble with. If you are uncomfortable with this, then I would recommend not continuing with this book. If you want to leave a request, you can. I will try my best to write as much as possible, and my stories will most likely be split into two parts.
Silently Sleeping (Underswap!Papyrus x Reader)
Underswap!Papyrus x Reader And some Fresh!Sans x Reader -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- It isn't hard to slip into a dream. You're happy with what your mind makes up and you stick with it until you wake up. Nightmares are hard to sink into. Death, tears, bloodlust, screams of terror and agony. You eventually wake up crying and wondering why your head would come up with something so sadistic. You're not in a dream. You never were. It's always been a nightmare. Always. -_-_-_-_-_-_-_-_-_-_-_-_-_- "My heart fills so... empty." "Please don't do this, (Y/n)!" "I'm sorry I caused so much pain... but we both don't have to suffer anymore."Complete
