Summary
After a forced extended break from writing (crazy how like a week is considered an extended break to me rn 💀), I found myself having a hard time getting back into the rhythm of things; I've also come to take more notice into how I struggle to write flash fiction.
So, I decided to take a crack at the solution by writing flash fics to revive my pace! And what better way to show my appreciation to some frequent commentors than to gift them?
Probably will end up being a reoccurrence if I find myself slumping, so lets see how far it goes! :)

Summary
On Hiatus.
--
You moved to Mount Ebott to escape your mother and her expectations. You expected for there to be nothing of interest there. So what if there are legends about monsters and missing children. Lots of mountains have missing people. Yet...You've been having these odd dreams lately. Each one lands you in a place where the sun never seems to set and an alien white light shines from the skies. You've accepted a task that has put you against sixteen monstrous creatures known as the Keilaises, large skeletal creatures made out of stone, earth, and magic. From each of these guardians, you must retrieve a shard in order to complete your quest.
You don't know if these dreams are real or not. With your sleepwalking issue becoming more and more frequent, these dreams seem to be out of control.
...What's this you say?
You're saying that monsters have come down from the summit of Mount Ebott?
...Did your dream have something to do with this? Or are you just going crazy?

Very, very unique. Not often I’ve seen one where it takes into account that since Undertale is in the future, they might have futuristic stuff. Also love how Yin has a lot of people that care about them. Also also, FINALLY someone mentions how the Horrortale bros would most definitely be frail and gaunt from the starvation! I’m extremely curious on how Dreamer connects to Yin and how the skeletal statues connect to the skelebros… 🤔

Summary
Who goes up to their friend that they've talked to only a few times, and just because they know their friend does sex work, they're like, "Oh, hey, yeah, uh, you wanna do some kinky shit with me? My husband doesn't want to but I'm bored.' Like. In what world. Ugh, mine, apparently.
While married to Sans for a few months now, and neither of you being particularly the type to have sex all that often, you couldn't help but find yourself more… curious lately. Unfortunately for you, as it turns out, Sans is not the experimental type, so he suggests that you look elsewhere to satisfy this curiosity.
It's a good thing your friend Lust is willing to help you without hesitation.

Summary
Most slave stories have a dark tilt to them, while I have read plenty with Underfell, Classic, and all of them have some messed up things, this story slithered into my mind, and I felt that I should write it. The question came of what would it be like if the Underlust monsters found themselves on the surface, and faced with the power of the humans were pushed into slavery. While a few tropes we expect from a slave story will be present, collars, submission, non con or dub con elements, there will be a few things that you might not expect.
While I have this tagged as a reader insert fic, the reader portion is due to some of the POV being done in second person. The MC is both the reader and an original character with her own personality and background, she has flaws, she has character, and she is a person on her own with a name. Be warned.
Sandera Huges is the heiress of a wealthy family, she uses her unique position to attempt to campaign for monster freedom as they come up from the mountain, sadly things don’t go according to plan and she has to change her tactics to find a way to give the monsters what they deserve after what humans have done to them.-

So, An Emo Walks Into A Skeleton Reverse-Harem... by Xx_s0d4s4rc0pt1c_xX

Summary
You're not happy to be here. You were, at first. It was an opportunity to escape, to try and live your life as an adult without the endless pressure of solo living. No demeaning parents, no shame weighing you down because you were a whole adult and only just starting to even think of moving out.
But ever since you set foot across that threshold, it was all downhill from there.

Summary
Sans probably shouldn't have been so surprised. After all, other versions of himself and Papyrus had been appearing for nearly five years.
But how the hell else is he supposed to take a strange, injured woman walking through an open portal in the basement, covered in chains? Calmly or unquestioningly?
He won't leave her alone, she's too kind, too inexperienced with the real world, but she's a hazard. Even she can admit that she could cause incredible amounts of damage if she were to lose control of her magic.
Hopefully, he and the others can learn more about the woman who calls herself Flora.REWRITE IN PROGRESS

Bonus Chapter: The One Thing We Can All Agree On by DJ_Harbinger
Fandoms: Undertale (Video Game)
07 Dec 2024
Tags
Summary
Yes, you will have to read the original story to understand this. Well, I guess you don't have to, since it's purely comedy, but you might be very confused.
An alternate way chapters 7-8 could've gone, but it ruins the emotional beats of the original, hence it becomes an "un-canon" bonus chapter!
(Though, in my heart it's canon, time means very little to me)Series

One might think that a world revolving around sex wouldn't exactly sit well with a haphephobic glitch.
Add a little bit of unsuspected friendship and drunkenness, and they might mesh together better than you'd ever think.

In order to keep the species alive, the Royal Scientists are working overtime on their research... when, one fateful day, a human falls to the Underground. While this human murders a large chunk of the remaning population, they are ultimately is stopped by the king who harvests their SOUL -- which will be used by the Royal Scientists in order to create a medicine to save monsterkind.
[ an underlust au that takes a spin on the original concept to present a thematically similar story, but with some slightly different aspects that have led some of the characters to take different roles. originally named "underlust reimagine." ]

It began with the Original, and branched into so much more. The birthplace of emotion and its embodiments, all the different Universes and their beauties and threats, the safe haven for all the lost or broken, and the tucked away corners that make everything possible.
