    Summary

    Kuro works for Chaldea, a secret organization tasked with maintaining peace and order. He’s willing to get a job done by any means necessary. His current mission? To infiltrate the city’s criminal underground and eliminate their leader. Easier said than done when the leader is none other than Mad King Cu Chulainn. And the cherry on top is a seemingly insidious third party taking hold of city’s citizens. A modern/mob AU.

    Summary

    In the multi-universal city of Ebott, there exists two types of monsters. There’s the Monsters made up of love, hope and magic. Then there’s the Fallen, monsters that should have died but somehow remain in the physical plane as literal manifestations of the monsters that go bump in the night. Vampires, zombies, ghosts are just some examples.

    Edge is a Monster who works as a detective in search for his missing brother. With him is Sans, an amnesiac Fallen who has a penchant for drinking blood, magic and ketchup (but not at the same time). Together they fight crime! And more!

    Summary

    While searching for his missing brother, Papyrus finds Sans a prisoner of an enchanted palace ruled by a monstrous skeletal beast and a wise gentle-skeleton. Papyrus agrees to give up his freedom in exchange for his brother’s. Not one to believe in fairy tales, Papyrus has to come to terms with the hidden, fantastical side of their world. And just maybe help free both himself and these two mysterious keepers.

    Summary

    Updated summary as of 1/18/2017.

    Underfell Papyrus finds himself in the Undertale universe. Scorning their acts of mercy and kindness as signs of weakness, he does the unforgivable and dusts a monster. With only a lazy, pun-spewing skeleton doppleganger of his brother putting up with his behavior, he tries to adjust to his new life. Everything becomes all the more complicated when the Human shows up in the Underground. The path to redemption is rough but with some support and guidance, he is willing to give it a shot.

    Summary

    It’s the 3 year anniversary since Sans entered a relationship with the Fell brothers. Since the beginning, he has always been more hesitant to participate in their… more intense sexual relationship. But he’s grown to love them with his entire being, and what better way to show that than to give himself up entirely to them for a night.

    Summary

    Once upon a time, the Tale Kingdom and the Fell Kingdom ruled over the underground land of Ebott. A surprise invasion by the Fell Kingdom led to the downfall of the Tale Kingdom, and brothers Sans and Papyrus become servants of the Fell royal family. Life for them was difficult but acceptable until Sans catches the attention of the Royal Magician, W.D. Gaster, who places a spell on them that forced absolute obedience to anyone from use of a single word and intent. With help from the most unexpected pair of monsters, the two brothers fight to break the curse and gain back their freedom.

    Rape/non-con not with any main pairings.

    Summary

    Who knew something as simple as breaking a leg would spiral into something like this. Sans definitely didn't.

    An alternative sequel to Regretti and deviation from Caveatelli. Please heed the warnings!

    Grillby ignored Sans's more than obvious flirting, believing it was nothing more than a prank. Until he sees this purple asshole of himself getting more intimate with his skeleton than he liked.

    Summary

    Sans and Papyrus are happily living on the Surface when a scarred, dark looking skeleton drops from the sky. Literally. He's rude, condescending and covered in dust. But beneath the rough exterior lies pain and regret.

    In other words, the Undertale bros decide to include UF Pap in their Sexy Times(tm).

    Summary

    Papyrus is killed by the human in a genocide run. When the world resets, he finds himself in a strange version of the Underground. Snowdin is a sprawling town instead of a simple one, there’s an ice cave near Snowdin and all the residents look just a bit different from how he remembered. He also meets himself—his fedora-wearing, kind of creepy, “My Little Boney” (WHAT EVEN IS THAT?!) loving self, who treats his brother like trash. Well the Great Papyrus is not going to stand for that! He decides to help his not!brother and make other him become a better monster. Because surely this other him had to have some redeeming qualities.

    Inspired by Tobyfox’s comments from the Undertale artbook (proto-Undertale) and the Bad Brother AU

    Summary

    Mettaton and Papyrus are happily together. Papyrus notices that Sans has an interest in them but is unwillingly to admit it. Well they couldn't have that. After all, the more monsters that loved Mettaton, the better. Gratuitous smut ahead.

    Summary

    Based off this fanart: http://symphysins.tumblr.com/post/155564675266/its-not-really-much-but-have-these-other-doods

    Papyrus is a knight-in-training lost in the forest looking for his weapon. Sans is a local forest deity with a penchant for pranking lost mortals that dare to step inside his domain. They both fall in love and deal with the consequences.

    Smut scene will be marked, though it’s not a huge part of the story and there’s a part in it that’s kinda important.

    Summary

    “DO NOT WORRY SANS. HOPEFULLY THIS VIBRATOR WILL STIMULATE YOU ENOUGH TO BE ABLE TO SUMMON YOUR SOUL.”

    “i, uh, don’t think that’s how they work bro.”

    “NONSENSE! I’VE READ THAT HUMANS USE THESE TO ‘MASTERBATE’ AND TO BECOME SEXUALLY AROUSED. IT’LL BE LIKE HAVING A PELVIC MESSAGE!”
    ---
    In which Papyrus wants to give his brother a good time. With ribbons and vibrators, oh my!
