Summary
Nightmare wasn’t at all expecting Dust to confess to him on a random afternoon, and it was odd that Nightmare couldn’t sense it coming. He didn’t believe he harbored the same feelings for Dust, even if he cared deeply for the other. He didn’t think he was ready to date someone so suddenly… So why did he say yes?
And then shenanigans ensue. Shenanigans that might include unpacking your childhood trauma. And also identity crises, it turns out. Maybe more.

Self proclaimed #1 Dustmare Shipper writes a self indulgence fic of mostly fluff and goofiness
(Summary will probably change, since this one kinda sucks lol)

Summary
As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.
The bus is almost out of energy- and has been stopped.
Or so people thought.
It began to tilt- right where you were very much slowly walking. Andddddddddd—
It didn’t crush you to death.

Summary
Disclaimers:
Several details in this fic are heavily inspired by 'Blue joins the bad sanses' comic, so go check that out
Canon innacuracies: Passive and Corrupted Nightmare are the same person, Ink is the creator and not the protector, Ink, Error, Nightmare, and Dream, are all gods, Blue, Killer, Horror, and Dust's specific au timelines were all destroyed, and i took liberties with how the void works. Also, no Cross sans will be mentioned, i don't know enough about underverse, and there will be some OC non-sans God/entity/things later on. The fic will be split into parts, each lasting nine chapters.
Schedule: Once a week, on Saturday, Sunday, or Monday, and i will post art or a reference sheet with every chapter. Trigger warnings will be specified in chapter notes. I've never written for undertale before, so please let me know what you guys think :3With that said, the actual plot: After an injured Error crashes into Nightmare and Co's home, a close bond starts to form between the two gods, both forced villains. In light of Ink's attempt to kill Error, Dream finally starts to lose it, and Blue gets dragged along.
Average chapter length is 500-2000

Summary
A Supernatural Au of the Sans Aus (they're human in this don't worry, they all have human names too). This story is written in 3rd person view, having the perspective of multiple different characters. The most common POV will be Dolores' and Silvios' (Aka Human Dream and Human Swap) In this, magic exists naturally, with it being most seen in fae, elves, and vampires. Fae and elves have the most powerful magic next to other magical creatures that are thought to be myths. Humans had been living just fine for decades, as many vampires were wiped out, same with all strands of werebeast blood. However, the population of both ad managed to skyrocket within the last decade, proving to be quite the issue. Despite the modern technology, humans have been unsure of how to deal with the rising threat of supernatural. Some turn to their religion, some turn to arming themselves, and others hide away in their homes like it's a pandemic.
Or if you want a short version: A Sans Au Supernatural Fan-fiction where they're humans, dealing with the struggles of surviving alongside one another.
