Summary
Falling into the Underground wasn’t on your to-do list. Falling for two skeletons definitely wasn’t either.
Blue is sunshine bottled in bone—sweet, loud, and determined to make you smile even if it kills him. Rus is quiet, steady, and the kind of person who remembers your favorite tea. Between the two of them, you’re constantly flustered, overfed, and very, very loved.
When both brothers realize they’ve fallen for you, chaos ensues—except it’s the polite, apologetic kind of chaos where no one wants to hurt anyone else. What starts as a tangle of awkward affection becomes something honest and warm: a relationship built on trust, laughter, and a whole lot of skeleton hugs.
“WE CAN SHARE THEM!” Blue insists, bright as ever.
Rus sighs. “That’s not how dating works, bro.” -

Summary
Here we are again! Another series of Undertale one-shots following the Fictober prompts and featuring the skeleton brothers as love interests to either my nameless or named girlies.
Just like the past two years, if you'd like any of these to be turned into fics, then please let me know in the comments! If enough people show they're interested, then it'll be added to my list of future fanfics! Five requests are what's needed for them to be added.
And if you choose to wait till the end of the month to read, that's okay! Requests can be made up until November 7th, when I post the list of the lucky winners!
Hope you all enjoy!

Summary
You should be dead. Everyone else in this god forsaken city died as soon as the barrier came down and these creatures, these MONSTERS, invaded Ebott City. You got lucky, or maybe not.
You had the bloodline of a mage. Which meant you could create barriers. In a moment of panic you had created a barrier in your apartment, locking you and your neighbor inside, and the monsters out.
But now the clock was ticking and you had a group of skeletons sniffing around your apartment, telling you that they couldn’t wait to drag you back to their den.
They meant as food…. r-right?

Alternative Title: I Found Myself In An Isekai Styled Game Of A Game I Barely Know
How’d I get so lost that I found myself in a different dimensional plane?
—
“why is it… every time i see you, your flavor text is always written as ‘confused’.”
“… It’s my default….”
“i find it funny how you sound both confident and confused with just that.”
—
Basically you fell in the middle of the Underground and you just remembered this is a game you played once and never thought about it again. No amount of isekai mangas, reincarnation manhwas, and magical manhuas could ever prepare you for what you should do in situations like these. Because honestly, the fact that you know absolutely nothing outside of playing the neutral route was already a disadvantage.However, you can’t remember if there was an element to the game that included the enslavement of the whole monster race after they got out of the Underground.
Nor can you remember that there was any sort of color to the status windows that keep randomly popping up out of nowhere. Not that you were complaining since these status windows are what keep you alive from this… chaos…

Summary
A spin off of Okami_Norino's story Kittynaped with a darker tone and twist.
You, a dog once loved and cared for, had been fighting in a place called the Ring for far more than you could remember. Yet on a wet thunderous day you had somehow managed to escape. With the so called 'King' of the ring on your tail along with his lacky you find yourself cornered and attacked until this really scary wolf looking dog saves you. Although a complete prick and an asshole you agree to see through the favor he expects of you now. The only problem? His "pups" aren't exactly puppies. Instead you are now stuck trying to heal your injuries with two grown ass wolf-dogs!
Ooh! You promised that day that when you see Gaster again you were sure you were going to bite him. -

Summary
A mutation has spread across the globe when monsters were released, humans either dying as their bodies couldn’t handle it or mutated with the rest.
The mutation was simple really, a change of dynamics. Humans started taking more unusual forms, growing more than a few ears, eyes, arms, legs, shit even a head at one point. Or body morphing differently altogether. Turning into their worst nightmares.
Y/N being a young child at the time of the outbreak changed with the rest of her family, half of her family died or killed themselves resulting in her being an Orphan at a young age, left alone in the world as her body shifted and changed. Body becomes leaner, smaller…cute. Cat-like ears and tail sprouting from her body, legs breaking and reforming into back hind legs of a cat's, fur covering her legs stopping at her waist.
Not only that, but she is an Omega.
Of course she doesn’t know oh no no no blissfully unaware, well that is until an over caring human Frisk decides to visit the Orphanage dragging along her friend Chara. Whom in turn absolutely dreads the visit. Let's say…frisk was the door to meeting a rowdy group of skeletons…

An scientist. Or what you called yourself, a mad scientist? You probably just wanted to sound cool. So much to the point of every other borrower wanted to explicitly kick you out of the pack. The only reason for your own mind hasn’t done such was because you were currently working on a medicine to help the sick borrowers.

—
“MY LOVELY, WONDERFUL DATEMATE WHOMST I ADORE. WHILE I HAVE A LOT OF FAITH IN YOUR DETERMINATION TO CANOODLE, I BELIEVE IF YOU ATTEMPT THAT YOU MAY PASS OUT.”
You flushed and glared up at him. “What happened to relocating, huh? You didn’t have any complaints 30 seconds ago!”
Papyrus bent down and met your scowl with a raised brow bone before he bonked his skull lightly against your forehead. “THAT WAS BEFORE YOU ALMOST TOOK A NOT-SO-COOL PRATFALL ONTO THE TILE.”
You huffed as you wrapped your arms around him. “I could suck your dick if I wanted. I wouldn’t pass out.”

Summary
An unfortunate accident one dark winter night sweeps you off your feet and leads you into a chance encounter with a house full of skeletons! They’re charming, witty and punny all around, but for reasons only known to you - you escape their friendliness intending to never step foot near the woods, or the skeletons, again… or that was the plan at least. What you couldn't have expected was that they're rather stubborn, and for some reason very intent on befriending you? No matter how much you avoid them or how many excuses you provide - they just keep popping up?! Why you?! Why now? And why are there so many?!
Will you be able to ward off your new skeleton suitors and keep your age old secrets, or will you succumb to their wily charms and submit yourself to their affections despite your unnatural circumstances? Will you be able to come to terms with befriending them or will you abandon it all, leaving them and all they are in the dark…
A tale as old as time, in which the reader goes through all 5 stages of grief trying to avoid the skeletons, with very little success and a ridiculous amount of shenanigans.
