Summary
"Deberías odiarme, Pepper! Soy un monstruo! Maté a mucha gente! Maté a mi mamá! Soy horrible!"
Le grito a Pepper con furia y ansiedad en mi tono, mis manos de metal brillan en respuesta a mi sentir, al verla retroceder con miedo escondiendo a Morgan detrás de ella me volteo intentando calmarme, después de varios segundos regulando mi respiración hablo más tranquila, sintiendo lágrimas saliendo de mis ojos por todo lo que deseo expresar pero no puedo, no siento que merezca decírselo, 'No merezco sentirme así' pienso.
"Yo no soy como el, Pots, no soy un héroe. El mundo lo sabe, tu lo sabes, yo lo sé... el.. el lo sabía"
Digo saliendo de la habitación sin volver ni voltear, empiezo a correr hacia la ventana abierta en la cabaña cuando escucho a Pepper llamarme, 'No, necesito ir con Bucky, no se porqué me siento así, se suponía que la terapia me estaba ayudando'. Digo saltando de la ventana antes de encender mis propulsores y dirigirme hacia la torre de los "Nuevos Vengadores" como nos nombró Valentía.

Summary
This was originally supposed to be my Kinktober for this year, but I ended up deciding not to do a full Creatober challenge at all, just because of how stressful it was last year
I already had some stuff prewritten though and didn’t want it to go to waste. Plus, I recently found a kink list that I’m super interested in ‘cause of how creative I can get with each prompt. So think of this sort of like a spiritual successor to Bossa Preciosa, but with various different breaks from SYIAD canon and several Multiverse AUs involved
TLDR: A bunch of smut that I wanna throw in your face before I run away. Enjoy~

Summary
On the day of their 13th birthday everyone has a name appear somewhere on their body. A script different than their own, but still familiar and comforting nonetheless. It's said to be your soulmates handwriting and, when you make physical contact for the first time, it's to change to the color or their eyes. Or so the rumor goes. But everyone knows that's just an old wives tale since finding yours is so far and few between.
But then there's Fanchon. What the hell is she supposed to do with 12 soulmates?? At least her odds are better than most...

Summary
In a world where Humans and Monsters exist together with mild tensions here and there, your only issue is trying to find a place to stay, growing tired of sleeping in your car. Well your only issue, besides the fact that you're a cyborg in a world that hasn't grasped the idea of combining human and machine. A secret you're supposed to be keeping but aren't trying too hard to. Luckily, an old acquaintance of yours is being kind enough to offer you a place to stay, and for a dirt cheap price! There was no way you'd turn down a real bed and a roof over your head!

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
There was no hope.
There was no way out of this place. Sans knew that from the depths of his soul- he couldn't escape on his own. But without any way to contact anyone and no knowledge of where he's trapped, all he could do was try to survive... or maybe just hope for death.
No more resets, after all.

On your last day in Ebbott City you make a wish into a fountain, and end up falling in. When you get out of the fountain however you find yourself face to face with a pair of skeleton brothers, and for some reason its now the 1930's???? It turns out that the Skeleton brothers are the head of the Mafia that runs your side of the city, and you now live in their district.

Summary
Sleep was not restful.
Dream tossed and turned, coming in and out of consciousness. He dreamt no dreams—only experiencing odd sensations and feelings.
The back of his neck felt warm for a moment—as if something was breathing near him.
He shot up, looking around wildly, dagger poised in his hand.
Nothing. What the hell?
He held his breath, not moving for a minute.
Listening. Waiting.
It was quiet again. Nothing but the brook—the fire had died out whilst Dream slumbered.
Relax. Maybe he imagined it.
He sat back down with a soft groan, not yet slipping his dagger back into its hiding place. He rubbed his neck and shoulder, skin still prickling from whatever just happened.
Ow. What?
He pulled his hand back, tensing at the sight of a familiar crimson.
Blood. His blood. He was bleeding. Why was he bleeding? HOW was he bleeding... Craning his neck, he froze. Two sets of puncture wounds stared back at him. -
