Flowey gets bored and decides to change up one of his runs. Papyrus presents an interesting project, for the moment.

It started with one moody skeleton crash-landing in your home. Then he started bringing friends. All of a sudden your apartment is a multidimensional nexus for an awful lot of monsters named 'Sans.' They're all a little rough around the edges, but they're sweet in their owns ways. You probably should have guessed they were the "bad guys" though. Oops? Alternate Summary: BadGuysOnly reverse harem

Now, this is a story all about how your life got flipped-turned upside down and I’d like to take a minute just sit right there I’ll tell you how you became a dang ass skeleton fucker. It’s been three years since monsters have integrated into society. After a frightening experience, you start to run into the same skeleton everywhere you go, and your lonely life soon makes a one-eighty turn.

Can you prove to the world that Take On Me by Aha is the greatest song ever written? Because it definitely, definitely is. PART ONE: Apartment - Chapters 1-50PART TWO: House - Chapters 51-98PART THREE: Home - Chapters 99-[tbd] The Reader uses she/her pronouns and is named--not a self-insert, more like a story in second-person. I don't generally reply to comments cuz I like an accurate comment count (2021 update: haha fuck that you WILL hear my love and appreciation. that is a threat). Author uses they/she pronouns plz default to "they" unless u know me, or yknow u can just call me Mod. Thank you! :D

Sans took his brother's hand and ran. They were never going back, never looking back. They could only go on forward, away, far away. Away from the tests, from the labs, and from Him.

So you try to end it all. Luckily Gaster has a solution. A reverse harem fic inspired by Skeleton Squatters and the Landlady byTyrant_Tortoise

You're not a people person; could you turn out to be a monster person instead? You're a typical awkward human, except... for some baggage. You've come to accept that no one wants to deal with another persons problems, so you've become a recluse. When your new skeletal neighbor starts probing, you put up your shields. You don't want to tell him. If you do, he'll leave. That's how it always works. Isn't it?

Heyyyy everyone! As you know the new big thing is for a dating sim rp book! Well guess what I'm hopping on the band wagon folks! In all honesty the only reason I'm doing one was I was getting irritated in each one that there wasn't any real stuff going on with the Bad Guy Crew (if at all) or it was just for weird stuff, so I was like let's go then, and have a Dark Dating Sim that actually will have actual villains.

For my wonderful beta reader, restlesslythought (Go follow her shit now; restlesslythought.tumblr.com)

Alex is just a gay ass guy with vague as hell premonitions and a lot of fears, he didn't ask to always be yelling at a skeleton just barely taller than him. He's not surprised when monsters burst from the ground like daisies, he's not surprised to learn there's skeleton monsters and he's not surprised that one just happens to be attracted to him in some weird, hateful way. What he is surprised about is how he feels the same way. And when Alex's younger brother shows up, all hell breaks loose.

This is a story about a small creature who had a temper and a human who thought that they knew what life had in store for them, boy were they wrong….. Intro: Lonely. That was probably something I used to be, now that I really look back on it. Maybe it was the same for him? Maybe that is why your life changed from white to black?

It hurts; to speak, to think, to try...

The Sans and Papyri of the AUs don't like how Slim is being treated so a few of them take him out for the day. But they chose the wrong time to do this act of kindness.
