Sans AU One-Shots

❀Horror❀ || hunger.

Pairing: Horrortale Sans x Female Reader
Prompt: You're stuck in the Underground - which was going just fine until you ran out of food for the very hungry monsters that won't turn down human flesh as a fine cuisine.
Type: smut
Length: 8.2k words
Background: It's long overdue, but here's a lore dump on Horrortale for anybody that doesn't know: Frisk completes a neutral run, killing Asgore and leaving monster kind with no human souls to break the barrier. Toriel tries to take her place as ruler but Undyne drives her out with her thirst for human bloodshed, which the doomed monsters support because of what Frisk did. It's during this time that the CORE malfunctions - which has been vital to the monsters' survival all this time - and now they're on a ticking clock to fix it while the monsters slowly go crazy/savage and starvation runs rampant. Undyne asks Sans for help finding a way to repair the CORE, and he works on what to do while maintaining his lazy facade and giving up his food for his neighbors in Snowdin. Alphys starts talking in Undyne's ear, and all of the suffering and tension and hangry chaos boils to a head when Sans shows up with plans to fix the CORE and Undyne tries to put a spear through his head to take his magic eye. He demonstrates his incredible power by catching it with his magic and sending it back at her (which takes out nearly half her face), but he collapses from exhaustion afterwards and she's able to remove the eye from his skull (how he got his cracked skull), which Alphys says can save them all and power the CORE back up. Her royal guards bury him out back, but he crawls out, killing them and stealing a bloody eye from one of them (where he got his eyelight). For a moment, Alphys appears to be right and Sans' eye turns the CORE back on, only for Sans to return and destroy it permanently and nearly kill Alphys with a forced lobotomy, ruining any future chance of salvaging their situation and leaving them all doomed to rot in this hell for their mistakes. Because of what Undyne did, he tells the other monsters to eat any humans they come across instead of harvesting their souls and effectively turns Snowdin against the Queen, basically becoming the town's leader.
I recommend reading the comic yourself tho, it's worth it for the artstyle alone but the story is also peak
Notes: I personally love the headcanon that Horror is a dang behemoth, and I 100% have a thing for guys that protect me so I kinda meshed those two ideas together to make this. (And, yk, Horror needed more love 🥲I love him so much but I was struggling with ideas. It wasn't intentional to ignore him so long-)

I searched frantically through my hiker pack, turning more desperate the longer it took to find what I was after. I was so lost in fear that I didn't hear the heavy footsteps behind me while I turned the pack upside down and dumped its contents onto the floor. Only old clothes I'd already dirtied, a first-aid kit, and a couple bottles of water fell to the floor. My hands found their way to my hair after my empty bag joined my belongings on the dirty carpet, where they tugged on the (h/c) strands as I wondered what I was supposed to do now.

The footsteps stopped as a large figure suddenly pressed against my back, and I felt cold breath tickle the hair on my neck. Goosebumps lined my exposed skin and I froze, every joint locking up except for my neck, which I angled upwards to find one blood red eyelight peering back at me.

"Heya," Sans' deep voice, gravely from lack of fluids and raspy from only recently waking up, made me relax.

"Hey, big guy. I...well..." I chewed on my bottom lip, stomach vocalizing its discontent as I rested a hand on it in embarrassment. The skeleton's eyelight flickered down at my flushed cheeks then the empty backpack on the floor among its last remaining items. "I'm out."

"'Out'?" he echoed, leaning back on his heels as his sockets narrowed like he misheard me.

"Yes, I'm out. I've got nothing left." I fell to my knees to rummage through my pack pockets just in case I missed something, but just like I feared, I found nothing.
