Fluttershy made her descent underground, sliding down on the loose dirt. Down where the mirror pool residing grew beautiful flowers know as, White Moon Blooms. Her intention was simple, gather up as much as her saddle bag would fill then climb back up and out.
She wanted to place the flowers inside pots to display back at her cottage, tying nicely together with the rest of her decor. She reached the bottom and began her search looking for a nice patch of White Moon Blooms to gather.
On the other side of the glistening mirror pool shined flowers with sparkling white petals and glowing stems. Those were the flowers she was searching for. No doubt. She made her way around the mirror pool to reach them and fill her saddlebag to it's boiling point.
Up above, where the sun shined through, a loud rumble echoed out through the underground cave. Darkness shrouded the cave as a boulder was pushed over the hole.
"Excuse me! There's somepony down here!" Fluttershy screamed, but her voice was too meek, and the ones above didn't hear her.
"Oh, my," She peeped out.
She quickly tried making her ascent back up the slippery slope she slid down. It was hard but she managed to make it to the top. She gave the boulder a hard push, trying with all her might to push it out of the way and make her escape.
But the boulder was too heavy, and she was far too weak. She drooped her head in sorrow and slid back down to the bottom. What was she going to do now. Nopony even knew she was down here, she might never get out.
A tear drop fell into the mirror pool, rippling her reflection. It caught her attention. The legends behind the mirror pool. She could make a double of herself to help with the boulder and make her escape. It was almost a sound plan, but she didn't know how the mirror pool worked.
Pinkie pulled it off, and that caused some major frustration for everypony in town, but she still pulled it off. Fluttershy didn't know the trick though. What was she to do. She waded her hoof in the water, testing to see how deep it went, then stepped in. The surface of the water came up to her neck.
The water is a bit chill, but nice feeling. She dunked her head under the water, letting it wash over her mane. While she's down here she could at least relax until she thought of a way to solve her predicament.
"Oh, I just don't know what to do. Angel and all my animal friends are probably worried about me. How will they get cared for if I'm not around?" Fluttershy pondered worried thoughts.
She began relaying back a nursery rhyme that Pinkie had taught her one day. The overly excitable pink pony was yammering so fast Fluttershy had no idea as to what the rhyme meant. Suddenly, she felt a heavy weight on her. Did the mirror pool just get deeper? It was impossible, she felt the bottom with her own hooves. But it had indeed got deeper, but only briefly.
She popped back up out of the water. The mirror pool's original dept came back, but now sitting in front of her, relaxing in the mirror pool as well, was... her! Or rather, a duplicate of her. A doppelganger.
That nursery rhyme she spoke out loud to herself turned out to be the very trick to getting the legendary mirror pool to work.
Fluttershy gasped at the sight. She couldn't believe her eyes. She tilted her head to one side, the doppelganger did the same, she tilted her head to the other side and the doppelganger followed in suit.
This was great! With another one of her they could hopefully move the boulder out of the way.
"Um, excuse me. If you don't mind me asking," it felt funny being polite to herself, but she wasn't about to let go of her kind ways, even for herself, "do you think that maybe you could help me move that boulder up there. You see I'm kind of trapped down here, and I just know all of my friends and critters big and small are worried sick about me."
The double of Fluttershy glanced up towards the boulder in question, eying it over.
"I don't know... it looks pretty heavy. And far up..."
This double of her's seemed more frightened that herself. Almost as if the double's scared personality was amplified from the effects of being cloned.
"Oh, I know it's far up, but I really would like to get out of here, so could you please help?" She asked her double once more.
"But---" the double let out a whimper.
"Please?" She pleaded once more.
"Oh, alright. I-I'll try..." Well it took some coping but finally the double saw reason, and started up the slope. The double only made it a fourth of the way up before sliding back down backwards.
"Oh, well. I tried," The double smiled and blushed.
The plan wasn't going well at all. The double of her didn't seem all that interested in trying to help her get out. Her previous worries were returning. Slumping, feeling depleted of all her energy do to depression, she made her way back over to the mirror pool and climbed back in. Relaxing in the cool water.
Her double, feeling bad, climbed back into the mirror pool with her.
"I'm sorry I couldn't help out. I-I'm just so afraid of heights," The double slid under the water, submersing half her head. A single tear flowed down her cheek into the water. She looked up at her double with a sympathetic smile, before changing her expression to one of 'oh'.
She shut her eyes tight, and grunted. Small bubbles boiled around her. She sighed, relieved. Her double heard the 'blurble' sounds of the bubbles boiling around Fluttershy, and gave off a soft giggle in reply.
"Nice one," The double complimented softly then unleashed a steady stream of gas. Bubbles boiling and even steam rising into the air. She was turning the mirror pool into their own personal hot spring.
Fluttershy found herself in an orgasmic state brought on by the warm feeling of the water brushing alongside her body. She waded over closer to her double, and pressed her plot firmly against her chest. She pumped out another poot, the vibrations tingling the double's chest, as the sound of it's squeak echoed throughout the cave.
Fluttershy looked on into her double's eyes. There was a sudden spark she felt. A passion began burning inside her. She's in love... with herself. It was perhaps the weirdest feeling anypony could have encountered.
The feeling of despair Fluttershy had was now just a fleeting memory. She knew she may never get back up to the surface. Never see her friends again. Never see her critters again. But at least she wouldn't be alone.
Fluttershy leaned in and planted a wet deep passionate smooch against her double's lips. She began lapping her tongue around inside her mouth. Their tongues batting against one another as saliva was exchanged.
Fluttershy pulled back, a thick strand of saliva connecting together with their tongues. She gazed longingly into her double's eyes and then hoisted her out from the water, sitting her down on the ground of the cave.
Dirt patted against the double's plot, and poofed between her crack. Fluttershy gently spread her double's hind legs wide open, and started suckling on her clit. Her double leaned back using her forelegs to keep her propped up, and began moaning in pleasure.
Fluttershy teased her double's clit some more with a playful lick, then moved down and licked at her crack, dirt smearing on her tongue. She clambered up onto her double and went in for another passionate french kiss. Saliva now mixed with dirt exchanging from tongue to tongue.
Her double blasted out a bellowing toot, Fluttershy moaned from the sound. She pulled back once more, saliva dripping and crawled back towards her double's plot and took a couple of a whiffs. First a short whiff and then a long whiff. Savoring the warm month old, sour cream aroma.
Her double proceeded to force more gas into her face, as she squinted her eyes, to avoid them from getting red, and lapped at her double's crack like a dog lapping up water from it's bowl.
Fluttershy whiffed deeply letting all the stench flow down through her nasal cavities, filling her lungs to burst with pure rancid gas.
Fluttershy's cares of ever being found and rescued were long gone. She was in heaven. She started pumping her tongue in and out of her double's filthy plot hole. There was a strong taste of fecal matter lathering onto her tongue. She fucking loved it, to put it bluntly.
They both moaned in unison filled with pure ecstasy. Fluttershy groaned and yelped out, 'oh!' as she pushed forth a loud and painful blast of gas. The smell of sweat from their passionate sex making fused with the raunchy smell of her gas floating around in the dank air of the cave.
Her double let out a loud and higher pitched moan from hearing Fluttershy toot, and leaned back placing her forelegs on the back of Fluttershy's head, forcing her to tongue fuck her plot hole fiercely.
Of course, Fluttershy had no objections. She was loving the disgusting taste of her double's plot hole immensely. She closed her eyes smiling, letting her double do the work of shoving her tongue deeper and deeper.
Her double groaned and grunted trying her best to blast some nasty gas onto Fluttershy's tongue and down her throat. In between each thrust of Fluttershy's tongue into her plot hole she would grunt once more. Finally, after a few more thrusts and grunts, she squeezed out a silent stinker that escalated quickly, leading into a flute pitch then down to a tuba pitch.
Fluttershy moaned, taking in several big whiffs of the nasty stank, that made her eyes water by instinct as she rubbed her hoof a few times through her sweaty crack than began playing with her own clit.
Her double was in full bliss as she thrusts in Fluttershy's tongue faster and faster, finally climaxing. Her pussy juices spraying out onto Fluttershy's mane and dripping off onto her face. She let out one last poot. A juicy one that pushed out built up waste onto Fluttershy's tongue, down her mouth and onto the ground in a splat.
The final poot and fecal waste washed into her mouth pushed her over the edge. She climaxed all over her hoof and onto the ground in a massive splat. She slid her tongue out of her double's plot hole and gazed into her eyes. She slurped her lips, and rolled waste matter against the cheeks of her mouth before swallowing slowly.
They both took a dip back in the mirror pool to wash off. Fluttershy leaned her head on her double's shoulder.
"You know, despite the situation I'm in. Possibly never seeing anypony ever again," tears formed, "I'm glad I'm not alone."
Her double wiped her tears then peered back up the tall slope at the boulder once more. She just spent some of the best moments with what little time she has been living. It was time to repay Fluttershy back for her love.
The double gently brushed Fluttershy to the side and stepped out of the mirror pool, trekking back up the slippery slope one more time. She slid down half-ways up, but didn't give in and continued pushing forward. With one final step, she had reached the top.
"I-I did it!" She exclaimed down towards Fluttershy, who was amazed to have seen her double tackle that slope effortlessly.
"Alright! I'm coming up!" Fluttershy opened her wings to try to fly up to the top, as it would be faster, but just as she expected the height made her queasy, and she was unable to fly. It was just like the time she got scared by the dragon's roar and had to climb the mountain. Her fear of heights always getting her. That's why she understood how her double felt before.
She hoofed it up the slope to the top just as before.
She gave a warm smile to her double, "Okay. On the count of three give a big push."
Fluttershy counted to three and they both heaved and pushed on the boulder, at first it seemed hopeless, but after some harsh grunting they both lifted the rock up and watched as it tumbled over.
They climbed out and dusted themselves off. The sun's warmth hitting their bodies. Finally...
Fluttershy was free. She checked her saddlebag, it was still full of White Moon Blooms. Her quest was not lost.
"Thank you, for everything. For the time we spent together down there, and for helping me out," Fluttershy gave a sweet peck on her double's lips.
"I know I haven't know you for long, or been living for that long," the double giggled slightly, "but I love you."
Fluttershy smiled. She never thought once in her life that her true love would end up being...
Herself.
