(SERIOUS WARNING, THIS STORY CONTAINS EXPLICIT ORAL, BUTTSEX, AND NORMAL SEX, AND MASTURBATION, AND DEATH. DO NOT READ THIS WHILE DRINKING OR EATING SOMETHING.) Everyone is comemorating Valentine's day, when two succubus decides to ruin the party by turning everyone on conscious-rapists zombies, insanes for sex and other carnal passions.

Il est 7 heures du matin et la voisine de Papyrus a décidé de ruiner sa journée. Papyrus veut simplement aller faire ses courses et rentrer. Papyrus perd patience. Papyrus est sur le point de devenir violent.

It's 7 am and Papyrus' neighbor decides it's an appropriate hour to ruin his life. Papyrus just wants to go to the grocery store. Papyrus is starting to lose his patience. Papyrus is that close to choose violence as an option.

Flowey finds himself all alone after the barrier has broken and released the monsters. While accepting his fate will be one of solitude forever, he manages to encounter a total stranger and shape up the interaction into a friendship. Though there's something strange about them he can't quite figure it out. (In Progress) (Post-Pacifist / Warning: OC!)

Creepy secrets are discovered from Toriel's journal

Years pass. People grow. The world moves on without you. However, through the threads of time, a connection is established. A red soul peeks through the darkness, a smiling man welcoming it with open arms. Flowey truly believed that whomever he spoke to when the barrier broke had taken his advice. However, four years after the monsters are freed, time reloads by a few hours.

(In Limbo) Down into the dark, Chara fell. Down into the dark, an experiment was run. What if she got to go home? But what if it wasn't to the world as she knew it? What if she was placed into another, at another time? What if that happened to be a version of Underfell?

I'm a member of the PTA/ I'm a member of the PTA/ There with the Frisk in the evening/ Fighting the s'burban moms (s'burban moms)/ Come on, dear teachers/ Come on, parents/ Late for the meeting and you'll miss the verbal wrecks/ Cover your kids ears because there is a show today/ Become a member of the PTA!

Sometimes Frisk just needs to reassure herself the pantry will always be full. Toriel understands. A drabble set shortly after the events of Hopes, Dreams, And DETERMINATION.

Frisk wants to save everyone, however, the consequences of every RESET finally caught up to them, when memories of the past threaten to break them and every friendship they've made they'll have to put things right, but Frisk can't do it alone, not anymore.

Why not?

You may have heard of a tale. Of the one who frees Monsterkind from the underground. This is a similar story. This is a story about a boy with a peculiar soul that saves Monsters and with the help of his friends brings two worlds together. (Crossposted on AO3)

The Riverperson is a very mysterious person in the Underground. Letting Frisk ride in their boat wherever they need it. They are always so carefree, but what if there is more underneath the surface.

Malory Wares is a massive Undertale fan, to the point she asked for Toby's permission to make and program a fan project of the fabled Hard Mode of Undertale. But when she uploads it, she is suddenly transported to the Underground, but in real life and no 8-bit graphics! But when she learns she has a soul filled with intelligence and magic, she must use them to go back home. Rated T

What if two humans were in the Underground at once? What if one human was DETERMINED to stop the other? What if they could both SAVE? What happens when an Unstoppable Force meets an Immovable Object? When a certain scientist pulls enough of himself together, he finally finds a way to stop the destruction of his world. (Undertale AU. Rewrite of DT.)

During the X-event a being known as Luna appeares and shed some light on Ink's current mentality.

ASK ME QUESTIONS HUMAN

"Might controls everything. And without strength, you cannot protect anything." A man falls into the underground and finds himself face to face with a demon. But he doesn't have the strength to beat them. In order to protect the ones he loves, he swore to do what ever it takes. Even if it means becoming a demon himself. (Based on XWolf26's DoubleTale)

It's been a good many years since Frisk freed the monsters from the underground. She is beginning High School and adjusting to life on the surface with her family. Things are going great until a new kid appears in her class. Arin, a loner, trouble magnet, compulsive liar who doesn't seem to have any friends. What will happen when a dark secret from the past rears its ugly head?

A collection of drabbles and oneshots, taking place in many scenes throughout the events and endings of the game. (DISCLAIMER: Frisk, Chara, Monster Kid, Napstablook, as well as various other NPCs use THEY/THEM PRONOUNS.)

Tell me my friend. A story as my eyes fall, one last story of how it ends, how it begins... and once its over let my eyes fall peacefully, and then when we meet again you can tell me everything new. "Well... it all began with a tear."

A household full of skeletons are competing over the attentions of one love. This isnt that house though. Unknown to the group secretively wrestling with their unpredictable love lives and universe-meddling machine, another house a few doors down has been gifted with its own skeleton posse clamoring for the attentions of their own little lady. A little old lady by the name of Mabel

Toriel helps humans wherever they fall down. Asgore has declared war on humanity. Both are different but share a common feeling though. What is it? Loss.

Sick of the resets, Sans does something about it. His means may be a tad unorthodox. One Shot

For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.
