Author's Note

Never tried writing a fear-messing story before, so I figured I’d give it a go. Warning, this one does get a bit darker and grosser (and not in the usual way) than most of my stuff. Wanted to really sell the, in my opinion, rather underappreciated horror aspect of the fallout series.

[Anthro, OC] Fallout Equestria: Amber Rain

Amber Rain felt a shiver run down her spine as she walked quietly down the desolate road running through her rural home town. The settlement was nothing more than a forest of dead scorched trees and irradiated plants now, leaving the hilly landscape barren of any familiar signs of life. Though she’d driven on it what seemed like hundreds of times in the past, it now felt like the road was plucked from another planet altogether.

The asphalt was full of cracks as if it had been shattered like a pane of glass. Sprouts of yellow-brown grass leaked through the gaps, infesting many of the burnt-out cars she’d already come across. Amongst it, glowing green mushrooms thrived, seemingly feeding off the surrounding radiation. Amber was pretty sure she’d be safe from that particular danger, at least for the moment.

Though she was wearing her bright blue Stable-Tec jumpsuit, the coarse wind still chilled the mare to the bone. Though, this probably wasn't helped much by the fact that the lower half of her jumpsuit was still quite damp. Two long dark streaks trailed down the interior of her legs, spreading down to her ankles. Their origin became quite clear when one followed it back up to a much larger patch that was centered over her crotch.

One of those giant roach things from the stable had attacked her almost as soon as she’d emerged from her stasis pod. Confused and disorientated, it had taken her by surprise. Thankfully, she'd been able to dispatch the oversized insect with a baton that happened to be lying on the floor nearby, but her victory had come at the cost of her bladder's release.

Though uncomfortable and a bit embarrassed to have wet herself, she was hesitant to actually take off the urine-soaked jumpsuit. She knew it was supposed to be at least somewhat radiation-resistant, and there was no telling how toxic the outside world might still be...

Suddenly, Amber was ripped from her thoughts as she spotted something up ahead. It was another car, this one parked on the right side of the road. It looked like it was in a bit better condition, but she wasn’t going to get her hopes up. Unfortunately, like most things she'd seen since emerging from the stable, it likely hadn't moved for over 200 years. Upon closer inspection, it was revealed to be covered top-to-bottom with a thick layer of rust and all four wheels were missing.

Amber gripped her baton tightly as she approached the abandoned vehicle. Bending over to peer in through the driver’s side window, she scanned for anything that might douse the one fear that had been slowly growing in her mind since exiting her stable. The fear that she might be the only pony left.

But before she could search the back seats, Amber suddenly gasped and clutched at her stomach. Her belly groaned loudly as her insides churned impatiently. As it turned out, being kept in cryostasis for over two decades hadn't done wonders for her body's digestive system. Her bowels suddenly felt heavy and bloated, desperate for long-overdue relief.

Amber quickly checked her Pipbuck to see if there were any structures nearby. Squirming as she stood next to the ruined car, her piss-soaked thighs pressed together, she was relieved to discover what appeared to be a small house on the map, not far from her current location.

Following the Pipbuck's directions, she quickly hobbled towards the waypoint on her digital map, leaving the safety of the road behind as she ventured out into the wilderness. Bounding over some rotting foliage and more yellow grass, Amber was eventually forced to stop and brace herself against a tree. The pressure on her puckered anus had suddenly intensified, very nearly catching her off guard. Thankfully, the surge of urgency from her bowels began to subside after a few moments, though it was sure to return again soon.

As she continued to jog towards her destination, she panted from the exertion of both keeping her asshole tightly clenched while also keeping up a good pace. After a few more minutes, she finally crested the last hill, revealing a small woodland cabin in small clearing up ahead. Glad to have finally found something that still had a roof, she bolted for the front door. Seizing the rusty handle, she flung the rickety door open and darted inside.

But before Amber could even start looking for some kind of bathroom, she was instantly assaulted by an intense odor that very nearly made lose her lunch on the spot. Covering her muzzle with one hand as her eyes teared up from the sheer strength of the stench, she looked around for its source. She gasped as she quickly located the source of the rotten smell. It was a dead body. A dead pony body.

Covered in horrible molds and more glowing fungi, the corpse lay reclined an old wooden chair by one of the cabin’s windows. Mouth left agape, small insects flew in and out constantly. The pony's eyes were gone, replaced by two sunken empty black sockets. Backing away from the horrifying sight, Amber felt tears roll down her cheeks from both the smell and what seemed like the confirmation of her worst fear. She really was the only one left.

Not able to look at the body any longer, she forced herself to look turn her eyes elsewhere and find what she'd come here for in the first place. Wiping tears from her eyes, she found a small dark hallway that leads off to two opposing rooms near the end. Flicking on her Pipbuck's flashlight, she cautiously walked down the hall.

In doing so, however, she failed to notice as one of the corpse’s fingers twitched...

Peeking into the room on the left side of the hall, Amber shined her light around what appeared to be a small bedroom. The windows were blown out and what remained of the bed was covered with small shards of shattered glass. An old dresser had fallen apart in the corner, releasing stacks of eroded cotton that likely used to be clothing. Feeling a cold shiver run up her spine, she briefly wondered if they had belonged to the body sitting in the main room Not seeing any sort of connected bathroom, she turned to check the door opposite.

In her increasingly desperate scramble for a toilet, however, she again missed the dark silhouette now standing silently at the end of the hall where she’d come from.

Turning the nob of the second door, she pushed it open to finally reveal exactly what she had been hoping for, a bathroom, at last! Better yet, the toilet itself looked to be still intact and was surprisingly clean all things considered. Grateful for her good luck, she quickly hobbled over to it, feeling another cramp slowly creeping up on her. After being forced to wait so long, her bowels felt like they were at the brink. If she'd had to wait another minute, she likely wouldn't have made it.

Amber began to reach up for the front zipper of her jumpsuit, only for a sound coming from behind the mare make her blood run cold.

"Grooaaan"

The terrible odor from before had returned, leaving Amber’s body trembling as she slowly turned her head around. What she was met with shot terror into the mare’s very soul. The corpse in the living room was standing in the doorway to the bathroom, it’s arms limp at its sides as it stared directly at her.

Swirling around, Amber scrambled for her baton, only for the monster to suddenly unleash an ear-splitting screech. It then lunged at her with a startling burst of speed, it's sharp bony fingers splayed out, going directly for her eyes.

With a shrill scream, it slammed into Amber like a battering ram, tackling her to the ground as she rose her baton just in time to catch the monster's rotting jaw before it could bite her. Panicked tears streamed down from her eyes as she wrestled with the abomination, screaming as its gnashing teeth crumbled against the steel she'd jammed into its mouth.

Kicking wildly, her bowels were all but forgotten about as several slender logs of poop quickly slithered through her anus, out into the seat of her jumpsuit. Far to focused on surviving with adrenaline pumping through her veins, she barely registered the increasingly large bulge forming from her ass. Amber sobbed as the corpse flailed its arms in every direction, seemingly determined to claw the flesh off her bones.

Using all her strength, she was finally able to toss off the abomination, quickly stumbling back up to her feet. She was left with nowhere to run as the monster rose up as well, it's jaw now visibly broken as it lunged a second time. With another terrified scream, she raised her baton and swung down at the head of the creature. With a resounding 'Crack!' the metal baton smashed through the monster’s skull, instantly pulpifying what little remained of its brain matter.

Stumbling back against the wall as she let the baton fall with it, the creature stumbled forward one last step before finally collapsing to the ground at her feet. It was dead. Amber's shaky breaths finally gave way to hysterical sobbing as she slid down against the tile wall behind her, finally coming to a stop as the thick pile of shit collected beneath her butt cheeks cushioned her fall and squished under her weight...
