Sans has been training to be in the Royal Guard for years, spending hours upon hours of training and playing out fake battle scenarios in an effort to be chosen by the Queen. Recently, Alphys has pushed some of the responsibility of teaching the young pupil onto his older brother, Papyrus, to strengthen their bond as family. He's much too lazy to fight, but he may have something else in mind.. UnderSwap Fontcest. Deal with it.

The monsters have finally made it to the surface and have been legalized to roam the surface as they please. The first couple of months have been spent as a paradise where humans and monsters have lived in peace and happiness. But as we all know, humans tend to be afraid of what they don't understand and the appearance of the monsters only seemed to have fueled the rising tension. You are a member of one of the biggest clubs that support the monster's appearance, known as the FMC (For Monsters Corporation). There is a rival club, known as the DM (Destroy the Monsters) that only wants to exterminate the existence of the monsters, and with every passing day, conditions only seem to be getting worse. Determined, you try to make things right and equal for all beings, but things start to alter when you meet with a certain skeleton. And with this certain skeleton, you, dear reader, reveal your biggest, most valuable secret...your little "defect". •°•°•°•°•°•°•°•°•°•°•°•°•°•°•°• COVER ART IS NOT MINE, I ONLY EDITED IT OUT FOR MY COVER. UNDERTALE DOES NOT BELONG TO ME, IT BELONGS TO TOBY FOX. I am simply writing this for the sake of my imagination, as well as for the entertainment of others. Thank you.

Yandere!Underswap!Sans x Shy!Reader And some Papyrus x reader -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- He was so sweet, so innocent. All he loved doing was cooking tacos, listen to his brothers puns, and try to be friends with everyone. Then you're pushed down a hole and end up in this strange new underground. After seeing you, his sanity breaks. Instead of making tacos, he loves hearing bones pop. Instead of listening to his brothers jokes, he bathes in blood. Instead of making friends with everyone, he kills them. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- "You can't escape. Not now. Not ever." -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Sequel to ending D: Silently Sleeping (Underswap!Papyrus x reader) Sequel 2: A New Life A/N edit: Apparently, I like this word cute. Oh, and, under a bunch of editing. A/N edit two: OH YEAH, and very cliche! XD
