Petunia Paleo explores a cave and finds a filly mimic. Surprise snuggles ensue.

When Petunia Paleo accidently finds a cave while digging, she couldn’t help but explore it. She would have marveled at some of the archeological discoveries all day if a certain chest didn’t change all of her plans.

At least the filly mimic inside the chest seemed friendly enough. One could even say too friendly.

The cave had been quite the unexpected find for Petunia Paleo to fall into. What was once a nice hole in search of another archaeological find soon had parts of the floor giving way and her tumbling into a cave underneath.

Each way seemed to stretch far into the earth, and with only the light from her hole, it was hard to see much more than the stone floor and walls that surrounded this place. After picking herself up and dusting herself off, it wasn’t long before she scrambled back up to the surface to grab an electric lantern and attach a rope to the top to make it easier to get back in the future.

Luckily, she hadn’t been trapped by the sudden drop; if she broke in closer to the ceiling of this place that may have been a different story. But now her heart was racing at the possibilities inside the cave, and she couldn’t help but light up the lantern and head further down. Maybe she’d find her biggest find of all. The bones of some ancient cave dwelling creature, or fossils etched on the walls; she couldn’t help but wonder at the possibilities.

But what made her stop in her tracks wasn’t any of that: it was stone. Specifically carved stone blocks. She gasped as she got closer and saw there was much more than just one or two on the wall. The rough tunnel was starting to transition to actual walls and a chiselled down floor. Rubbing her hooves and squeaking in glee she got up close to look at each one of them.

Who had built these? Somepony had to, but when was the bigger question. Was this recent or was this an ancient tunnel from ponies long ago? There wasn’t any obvious way to tell, at least not until she brought a few more tools that might help her examine these. But for now, that was something she’d get to later.

It was a good thing nopony was around to hear, because they might be thinking she was giggling like a madfilly when she finally trotted along the relatively smooth floor. “Wow! How cool is this!” she couldn’t help but say to herself as she trotted along through the corridors and giggling even more. Each spot she found, each room and staircase probably hadn’t had light shine on it in quite a long time.

She was in a place of history.

As she was walking along the side of a particularly large hall, there was a soft clunk of something closing. The sound startled her as she flashed her lantern around to look for the source. Maybe it was a rock falling from the ceiling? But there wasn’t any rocky debris lying around. Besides it sounded almost like a door closing, or a-

The light shone over a chest on the other side of the room. “Maybe it was a chest closing…” she mumbled under her breath as she looked it over. She swore she heard it close, but maybe it was just her imagination. She was the only one in here after all.

The surprise started to calm, and the previous excitement of exploration started to take hold again. She hadn’t seen any real evidence that anypony actually lived in this place, but a chest was a sure thing! Maybe it had treasure in it, or secrets of this pony civilization that she could put in a museum!

Trotting over to the chest she couldn’t help but admire the craftsmanship of it: simple and functional, with oak wood planks and iron bands along its edges. However, what stopped her in her tracks again was a small giggle coming from inside the chest.

Her eyes widened wondering who or what was in there. “I know you’re in there!” she called out and shined the lantern at the chest. “Dust Brush? Gentiana? Is that you? Did you sneak in here just to scare me?”

She smirked as the chest went silent. “I knew it!” Trotting over to the chest she put her hooves to the lid, ready to open it up, but oddly enough the lid felt warm, like really warm, almost like it had been sitting out in the sun on the surface and wasn’t stuck down in this cool cave.

Before she could lift up the lid however, it started to open by itself and two eyes peeked out from within. She expected one of her friends to sheepishly pop out from there, but instead it was somepony else entirely! The pony was an earth pony filly like her, but with a milk chocolate coloured mane and a yellow-khaki fur.

“U-uhhh.”

The pony slowly lifted the lid just a little more until her hooves were curling around the edge of the box. However, the inside of the box wasn’t what Petunia expected at all. It was purple all over, and a veil of purple slime connected the sides of the lid to the box, stretching apart as the lid opened. The filly within was staring right at Petunia with a sly smirk on her face, like somepony who was playing a prank and had her just where they wanted her.

A hoof reached out and tapped Petunia on the nose. “Boop!” the filly called out.

“W-wha-?” she let out and paused as her brain tried to figure out what just happened.

Before she could even ponder on it any longer, the filly’s hooves reached out, grabbing Petunia by the shoulders and pulling her in. For the second time today she was tumbling somewhere completely unexpected.


The trunk of the chest clunked closed. That was certainly the sound she had heard earlier when she was exploring the room but much louder since, well… she was completely inside the chest this time. Luckily, her electric lantern was pulled in with her, but it wasn’t like there was much to see in this purple expanse, except for the filly looking right at her. Petunia had her hooves curled up against her chest, and the filly was lying with her hooves on top and her face close enough that she could catch the fruity notes on her breath.

“Hi!” the filly said, looking all over Petunia’s face with utter delight.

“U-umm… h-hi?”

“I caught you!” she said and started giggling almost as much as Petunia was earlier.

Petunia looked around at her purple prison. It was surprising that both of them could fit into this chest, but even if it did seem bigger on the inside, it wasn’t by much. They were still squished up tightly against each other, and she didn’t really have much room to even wiggle. “W-were you the one giggling in the chest?”

“Mmhm!” she said with a nod. “You fell right into my trap! I bet you thought you were going to find a pile of gold but alas you found me, Small Fortune instead! Hehehe!”

“W-what? No! I was just looking around… I wasn’t looking for gold or anything. Promise!”

“Well what are you doing in here? You must be some kind of adventurer or dungeon raider of some sort at least.”

“No, I’m not any of those!” she said as she shook her head. “My name’s Petunia Paelo. If anything, I’m an archaeologist who just stumbled into this place and wanted to take a look.”

“Hmmmm…” Small Fortune hummed, and oddly enough the walls behind her seemed to vibrate at the same tone for a moment. “Well I guess that is still fine, I still caught you, Petunia Paleo the Archaeologist.”

Besides being covered in purple, the inside of this chest seemed out of the ordinary. The floor she was lying on and the wall her head was leaning against both felt damp against her fur, and instead of wood, it felt more like she was lying on a warm bed of gel that was giving her a hug from all directions. And the pony proudly lying on top of her was another thing entirely. She looked like a filly… well part of a filly. Her body seemed to be fused into the purple wall, almost like her and the wall were one.

“What happened?”

She must have caught her glancing down below. “Nothing happened. Well, you found me. That happened, but then boom! Surprise! And I got you! Hehehe.”

Petunia tilted her head a little. “No, I mean like what are you? What do you want?”

“Well, I’m a mimic! I’m supposed to steal your gold and things… I think…”

“I… don’t have any gold,” Petunia said hesitantly.

“O-oh?” Small Fortune said with the first hint of confusion on her face that showed so far. “You don’t? Are you sure?”

Petunia nodded. “I’m sure… uh… how many times have you done this before?”

Small Fortune glanced away as a blush started to appear on her cheeks. “Tonnes… many times… to so many ponies! This totally isn’t my first time doing this with a real pony after only practicing with rocks!”

“Oh,” Petunia giggled nervously. “Well, you certainly did a good job at it… I mean, you did catch me.”

“You mean it?” she said with a big smile on her face and eyes lit up so much they were practically sparkling.

“Mmhm! Yup! I bet you’d catch any adventurer coming by these places no problem and get all of their go-“

“Oh thank you, thank you, thank you!” Small Fortune said as she hugged her tight. But it wasn’t just her hooves hugging. The walls squeezed around her entire body from head to hoof, like the entire chest was hugging her all at once except for her muzzle that she was able to take laboured breaths from.

Eventually the full body hug relaxed and the gel-like surroundings peeled off of her fur. It felt strange enough that Petunia couldn’t help but squirm at the feeling, like a bunch of tiny hooves stroking through her fur as they left, tingling in some places more than others.

“Y-you’re welcome,” she said carefully, hoping that it wouldn’t send her into another hug. But it was strange having a pony… or a mimic, on top of her like this. Petunia’s hindlegs were straddling Small Fortune’s barrel and with the walls squished so tightly against her, it was touching some pretty personal places.

“Nnyh,” Petunia softly let out as she wiggled her rump a little, and felt the gel peel away from between her legs. However, oddly enough it felt like it was pressed in a little deeper at the spot and it managed to gently pull at her skin below as it slipped off. Her hind hooves tapped against the ceiling, feeling more of that gel and none of the wood she was expecting. “S-so… do you think you'll be letting me out soon?”

“What?!” Small Fortune looked at her like she had just said she was getting a whole herd of giraffes. “No. But I caught you! You’re mine! And we just met! I can’t let you go until I get your gold!”

“But I don’t have any gold,” Petunia clarified once more and stopped the filly’s stammering.

“Well… umm….” She let out a sigh. “Ok, I guess I can let you go... eventually. But not now! You’re mine for now… at least a little longer. Besides, it feels kind of nice having a pony inside me. Especially you. I like you!”

“That… sounds ok. I could stay with you for a little longer if you promise to let me go.” It wasn’t like she really had plans for the rest of today anyways besides digging, and this new mimic filly did seem genuinely happy to meet her. Petunia wiggled a bit more as she felt the start of a hug coming on. “But! Could you at least not squish up between my legs like that… it....”

“Oh, does it hurt?” Small Fortune said as she moved the gel wall back a bit and it gently pulled at her filly folds once more.

“Nngh,” Petunia let out and her hind hooves twitched and tapped against the top of the lid. “N-no… it just… kind of feels weird.” It didn’t help that her tail felt like it was trapped inside the gel wall, slowly getting pulled on like the rest of her fur.

“Weird? What is it?”

Petunia bit her lip and shrugged a little. “It’s umm… my flower…”

“Like a garden? You have flowers?” Small Fortune looked down with an almost excited curiosity.

Petunia could see a little bit too through the small gap between the two of them; the darker shade of blue fur that started at her teats and went all the way down between her legs. “No, it’s not actually a flower… it’s umm, my fillyhood, filly parts, hidden treasure.”

“Treasure?”

With Small Fortune’s eyes going wide once again, Petunia gulped a little. “It’s just something Mom called it! Because it’s important... and you should try to keep it hidden from others.”

The hoof trailing along her belly and further down seemed to be doing the exact opposite of that. The hoof paused as soon as it brushed against her teats and Petunia suddenly shivered. “Well if it's an important treasure, it’s mine since you’re mine as well! I want to see it,” Small Fortune said as she glanced back up at Petunia.

Petunia bit her lip, and huffed at the feelings swirling around inside of her. Her heart was beating louder in her chest and the already warm air felt even warmer now. Why was the focus suddenly between her legs? “F-fine…” she hesitantly said and watched the filly mimic’s eyes light up again. She might have been able to talk her down from doing it, but it wasn’t like it was going to hurt if her fillyhood was looked at. Besides, as forward as the mimic seemed, she looked almost happy to get permission.

Small Fortune’s body seemed to sink into the purple walls as she slid down and stared right between Petunia’s legs. “This doesn’t look like gold,” she said with a small poke of her hooves to the middle of Petunia’s fillyhood.

“A-ah… i-it’s not gold.” She squirmed around as Small Fortune poked around even more, but there wasn’t any place to really go. The mimic’s head was between her legs so she couldn’t squeeze them closed nor spread them any more with the walls pressed against the sides of her legs. Her hips shifted from the touches until they bucked in the only direction they could go: up.

It tapped Small Fortune in the muzzle and the mimic only blinked back up at Petunia; a small string of liquid connecting the two together. “Heh… boop.”

Petunia couldn’t help but giggle at the absurdity of it all. How a strange pony mimic inside a mysterious cave was suddenly a hoof away from her fillyhood and getting booped in the muzzle by it. Her giggles continued even as the Mimic noticed the string and reached out her tongue to taste it. Another light lit up in her eyes as her muzzle followed the trail.

“A-ahh~! H-hey~!” Petunia couldn’t help but shout out as soon as she felt her new acquaintance’s tongue licking between her legs like she was a melting ice cream. Her legs squeezed shut, but only pressed against the mimic’s head.

Petunia’s hips rocked as the tongue kept licking firmer each time. “H-hey! I didn’t say you could lick me down there!” Thankfully, the mimic pulled off from her, enough that Petunia could catch her breath for a moment. She was panting, almost like she had gone on a small jog.

“But you’re tasty! Is that why you wanted to keep your treasure hidden?”

“W-what? N-no, just ponies aren’t supposed to be down there… and… and… tasty? Y-you think I’m tasty down there?” Petunia shook her head a little, trying to focus, but there were a lot of emotions floating around in a strange storm inside of her. It felt strange, it felt wrong, but it also felt somewhat nice, and Small Fortune seemed to be enjoying it.

“Mmhm! You taste great! See!” Petunia shivered more as a tongue dragged between her filly folds, until the mimic’s tongue was glistening with a sheen of juice. The mimic wiggled back up and stuck out her tongue flat against her chin. “’ere!”

Petunia looked around with a growing blush on her face. It was one thing to have somepony else doing this to her, but it was another for her to actually be doing it herself. Hesitantly she stuck out her tongue and licked up some of the juices… some of her juices.

If her face wasn’t hot it certainly was now. Small Fortune watched as Petunia sampled herself. There was almost a light blueberry taste to it, mixed in with some earthy notes; as well as some more fruity tastes, but that might have been from Small Fortune herself since she did kind of smell like that already. It was almost surprising how enjoyable the taste was, a hidden flavour she never expected to find… especially not down there. “It’s… nice.”

“Yes, it’s good!” Small Fortune smiled and nodded as fast as an excited puppy would wag their tail. The two blushed again as they glanced at each other. Their muzzles were so close when the mimic finally slowed her head.

Petunia’s heart was beating like mad in her chest as she played around with an idea in her head; one that she was starting to get curious enough to try. “D-do… you think I could taste it again?”

“I… I um…” Small Fortune almost seemed to be taken aback at the question, but she flicked out her tongue anyways.

Petunia licked the filly’s tongue with a little more initiative than before. It wasn’t as flavourful as the first time, but that wasn’t really what she was after. She licked again, until she just kept her tongue there and pressed as they stared into each other’s eyes.

She could feel the drool starting to pool at the corners of her mouth, threatening to roll down her cheeks, but Small Fortune was first to suck back the growing wetness. However, their muzzles didn’t move; in fact they got closer. Their lips met each other this time as they slowly started to give little kisses. They still looked at each other, but Small Fortune was the first to have her eyes close a little as she pressed into the kiss.

It was almost like having a coltfriend… or what the idea of having one was like. Ponies were just supposed to kiss each other eventually once they got close. It was just like a rule that she knew, or something that other foal would tease each other about on the playground. But the strange thing was that Petunia never really wanted to kiss a colt all that much. She had never kissed a colt before, nor a filly either, but now that she was actually doing it with somepony – a filly like her – it felt almost magical.

“Mmm~” Petunia’s hooves grabbed at the filly’s shoulders, pulling her in closer for her own little hug. But the walls around her were pressing in tight as well and even shivering a little bit whenever the mimic let out a few small sounds of delight to match her own. Even between her legs it was pressing in a bit tighter than normal, enough that it made her rump wiggle and only added to the feelings down below.

Even if she had said she wanted some space down there, she wasn’t sure if she was feeling the same now; almost like she wanted her new friend to be there just a little longer. Her hooves pressed against the filly, while her hind legs squeezed when everything felt like it was getting too much. The gel walls below felt like a broad tongue that was trying to lick and squeeze her. It was hard not to just surrender into this ride.

“Mmmm… whoa…” Small Fortune said as she pulled back, sounding just as out of breath as Petunia was.

“Y-yea…”

Petunia watched as the filly glanced away, looking like she was starting to get embarrassed too with whatever was in her mind. “D-do you…” the mimic started. “Want to try my hidden treasure too?”

“Oh…” Petunia let out automatically, blinking a few times to process what she just heard. With the way the mimic’s body was part of the wall, there didn’t seem to be the same parts that were obvious. But another surprise today couldn’t hurt. “I could give it a try… y-yea.”

The squeezing from all angles relaxed a bit as the filly mimic spun around along the wall surprisingly quickly. Petunia looked up at where the filly’s yellow-khaki fur on her belly blended with the purple of the wall and watched as the purple gel started to recede. Two dark nubs started to poke out, and then the mimic’s own fillyhood started to come out of hiding.

Something about how those puffy lips and the small trail of wetness reaching out between those folds and the wall made Petunia stare hard at the sight above her. The purple was gone from between her flanks and only connected to her dock like some kind of false tail. However, with how close everything was in here, the filly’s rump was surprisingly far away.

Small Fortune seemed to just stay there, waiting and standing above her. Wasn’t this what the mimic wanted? Petunia looked a little confused, but reached out her hoof, grabbing her friend right where her cutie mark would have been. The walls shook a little, almost like she had startled the mimic at the slight touch.

“It’s ok,” Petunia said, hoping that was somewhat reassuring. But eventually those flanks started to descend and a weight returned to the filly’s chest. She was pretty sure neither of them moved for a few moments. Petunia was just staring at those lips, watching how they were slightly parted, revealing a pinkish purple within. The heat was radiating onto her face like she was looking at a small fire; the mimic was hot, but this was even toastier.

Even if they were still, she could still catch a small quiver or a small dot clenching at popping out every so often. It made a wet squish every time it peeked out. She might have tried giving it a tap with her hoof, but they were currently trapped between the mimic’s side and the wall. With a little hesitation she stuck out her tongue and poked at the dot. “Boop.”

A small squeak sounded out as Petunia poked it again and felt that dot tap out against her tongue even more. It seemed to kick start the mimic back into gear, as she felt a mane brushing up against her thighs and a warm breath between her legs. A shiver went down her spine as she felt a tongue tracing along one of her folds.

Both of them flicked their tongues at the other, sporadically feeling around like a bird pecking around for a delightful morsel. Petunia was starting to like the unique taste that was seeping out; a distinct grape, yet with an odd mix that reminded her of wooden furniture.

Small Fortune seemed to be getting more delighted too, mentioning the taste a few times as she licked with more gusto the longer this went on; each lick exploring more of her and lapping up the juices that she could practically feel coming out.

A sudden tongue further down below made Petunia suddenly jolt. “Bleh! Not as tasty!” the mimic called out suddenly before licking her hoof to cleanse the palette.

Petunia couldn’t help but giggle at the thought, making a mental note of places to avoid in her own exploration. But this pony’s fillyhood seemed more than enough to keep her busy. The parting folds made it easy to find her way in a little deeper, getting at the hot honey that was hidden inside and lapping at the inner parts of her entrance until it started to shake.

Small Fortune seemed to find that place too, her tongue burying itself in deep to reach even more of the juices. But it didn’t feel like it was just the entrance her tongue was reaching, it felt further than that. It was like her tongue was a long snake, pushing more of itself inside and spreading open walls than had never opened before.

Petunia’s hips bucked, feeling like her belly was getting tickled from the inside with how deep that tongue was flicking around. Even as she pressed her own muzzle into the mimic’s slit, reaching her tongue in as deep as she could, there was no competition in depth. She only hoped that her friend was feeling as nice as she was right now.

She could feel her tunnel grabbing at the mimic’s long tongue, clenching tight as it slipped around inside her. It was hard to focus on anything else beside the growing feelings between her legs and the squeezing against her muzzle. It was almost enough to forget to breathe as she licked, only to come gasping up for air when her lungs started to burn.

But she dived right back in, licking, kissing, slurping and sucking every part that she could reach. The chest was starting to shake and the walls around her were starting to convulse the longer this went on, even Petunia’s own hind hooves were tapping against the ceiling as they twitched on their own. Her legs squeezed around the mimic’s head as she closed her eyes and let the licks take her away.

The feelings were built up to the breaking point and suddenly everything let loose. She felt almost weightless as a warmth bloomed out from her core and spread to every part of her body. She gasped and let out a long moan into her friend’s folds as she felt her fillyhood clamping down, trapping the invading tongue for a few moments.

She almost didn’t catch the gush against her muzzle as Small Fortune pressed back and rubbed onto whatever she could reach. The fresh heat soaked her cheeks completely and ran down her chin and into her orange sash.

Heavy breaths filled this container as the two laid there for who knew how long. Petunia felt wet, messy, and dirty, but yet a warm afterglow made this feel so delightfully welcome. It was almost a shame when the lid of the box opened and the cool air of the room made itself known against her fur. She wiggled and slid as she was pushed out, barely managing to stay up on her wobbly legs when her hooves touched the floor.

“I… need to sleep a bit. You can go,” Small Fortune said as her head laid on the edge of the box with half-lidded eyes struggling to stay open.

Petunia gulped a little as she stayed close. The freedom was something she wanted, yet it felt strange to finally be standing outside. “That… was nice…”

“It was…” the mimic managed to say after pausing for a while to think.

“Well… I know where you are… maybe next time I can carry a few bits on me and you can try to take them from me?”

Small Fortune looked at her before the two shared a small smile and nuzzled their muzzles together.

“Your treasure will be mine again.”
