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 and her family's lives. But the King will only do it on one condition: he gets her soul. So with no choice but to die for her mistake, His Summoner promises him her soul when the job is done. | - Demon! Nightmare Sans x Female Reader - A little bit of a reverse harem with plenty of Bad Sanses x Reader moments (with a canon reason for it :D), but ultimately, (Y/n) is Nightmare's - Honestly you could read this with no prior knowledge of any of the characters and you'd be just fine - Kinda a slow burn? But don't worry, I throw in so many subtle/not-so-subtle intimate moments with all the Sanses that it makes it worth the wait :D - I'll throw in some bonus chapters with the other Sanses for extra (non-canon) fluff that doubles as a breather from the story, too - Is the relationship toxic? Maybe. I mean, this is canon Nightmare after all. But that's the beauty of a fictional story, no? - A lot of the symbolism and hidden meanings aren't obvious, so you might have to be on the lookout to see them (and keep in mind: Night doesn't openly show many emotions, so the devil is in the details) - I'm not going to spoil anything, but for all you anxious readers out there like me, I'll divulge I'm a sucker for happy endings *wink* - It's my interpretation of the characters (kept as canon as possible)

Do you love Sans? How about the numerous AU versions of him? Of course you do, that's why you're reading this. So if you're looking for some X Reader oneshots with your favorite Sans, I might be able to sate that craving.
