Honestly not sure why this is a thing but it is, I don't plan on making a ton of these one-shots but at least for a handful of characters. Should be fun.

It was a hot summer day in Kanto. The pidgey were chirping as they flew overhead and tauros slowly traveled across a nearby field grazing the calm day away. In the middle of this forest stood a large stone waterfall pouring rapidly down into the river below. The rocky cliff side had plenty of divots for 19-year old Misty's hands to grab a hold of and pull herself up closer to the top of the ledge.

The youthful redhead had taken a break from her time as the Cerulean City Gym Leader today to make another intense trek out in search of that shiny magikarp she heard so much about recently. Carefully scaling the cliffside she thought how she must be getting close as this is the last area near water for miles. The temperature was less than ideal but at the moment the occasional cool droplets from the waterfall felt good on her arms and legs. Misty thanked herself for going with her old look of a yellow crop top, jean shorts and gym shoes for anything more would have her overheating.

"All this work just on a hunch, it better pay off" she grumbled to herself as her muscles burned from the climbing. Eventually Misty dragged a leg across the top of the ledge and pulled herself on top of the cliffside. She stuck her hands in the rushing water and took a few mouthfuls of fresh water before standing up and continuing on her way.

Some 20 minutes later the air had become a bit musty and Misty's legs grew sore from all the walking. She wiped her forehead with the back of her hand noting the wet shine on her hand afterwards. Scanning the area Misty saw no pokemon in the water and very few in the trees a few feet away.

"How strange, the area isn't very densely populated" Misty spoke softly to herself. "Though that could indicate some rare water pokemon live here undisturbed. I need to find a larger pool of water and last time I checked the maps there was one up here, but where."

After searching, Misty continued in a promising direction though with her eyes sharply searching for something notable, she didn't see where the ground was weak from deterioration. One wrong step later the ground under her broke and she fell on her butt with a thud.

"Ow, ow, owww" she moaned. "That sucked".

Misty quickly realized the rocky terrain in this spot starts to slide down into a cavernous system. It would be quite difficult to climb one's way out without a ground or rock type pokemon, which of course she wasn't a wielder of. Though she luckily caught herself. Misty begins to push herself up onto firmer ground but her pressure causes more of the ground to break and she begins to roughly slide down towards the caverns with a high-pitched scream.

Misty's eyes could not adjust to the darkness she was now submerged into. The one bit of good news was she landed on her feet so other than some stinging scratches on the back of her thighs, she was alright. Well as alright as one could be stuck in a dark cave with an awkward smell in it while cold sweating so bad her clothes began to stick to her.

Feeling around on the ground, Misty couldn't find her bag, though just in case that happened she put her pokedex in her pocket. Pulling it out she turned it on and it shot out a small light. It could barely light up a wall but that was enough to start finding her way around. It was so quiet, not even any zubat were floating around. The pure silence was more unnerving to Misty than if there were pokemon down here. The even ground made her stumble a bit but Misty searched for some kind of exit tunnel. A few minutes that felt 5 times as long started to get her worried.

"Such an elaborate cave system and I still haven't found any daylight. If I don't hurry I could be stuck down here all night" Misty says to herself. "And with this benign so big, why aren't there any pokemon using it as a home?"

Misty soon after got her answer when she heard some kind of slithering sound. She quickly turned off her pokedex and backed up against a stone pillar. The sound over time grew louder as whatever it was shifted through the tunnels. Misty took it back, being alone in eerie silence was better than this foreboding presence. This thing sounded big, and like it had a bunch of tentacles to move around on. Thinking of the filthy bug pokemon she would get spooked by Misty's heart began to pound.

The creature moved around a corner, coming near the pillar she stood at, could it have heard her scream earlier? The strange scent that was in the cave before got stronger, it was rather sweet like cinnamon spice. Unsure how, that smell was making Misty shift her legs as her arousal began to twitch. She was trying so hard to be quiet, just let the pokemon pass and move on.

The creature was now right behind her, the tentacles running along the floor and walls of the cave system and propelling itself forward. One of those tentacles wrapped around the pillar Misty was using as a hiding spot, the slimy juices it excreted dripping onto her face and arms. The slime smelled good, and it was more smooth than sticky. Misty couldn't believe it but she was getting wet; which was rare enough for her, but in a situation like this, seriously?

Thoughts filled her head, those tentacles grabbing her and dragging her away. But her nerves weren't so fun from fear anymore as they were from curiosity. It might rip her clothes off, pin her down, running those slimy things all over her. That pokemon was big enough to do whatever it wanted to her, and the scary thrill of being dominated had her heart beating for that reason now.

Misty didn't know when she started, but her hand was on the crotch of her shorts. She rubbed in little circles making her breath quicken, her nipples sharply pressed against the fabric of her tight yellow top. It was difficult to whisper and not let out more sounds but she needed to touch herself. Her hair started to plaster itself to her forehead as she heated up her sweaty body more. The pokemon was already starting to pass by her though it seemed to slow down, looking for something that wasn't there. This could be a new discovery Misty thought, she has to know what kind of pokemon this is. If it's a new one, she could get a lot of credit for discovering it. She pulled out her pokedex and set it to mute, pressing the identify button and-

"No information available" the device said in its feminine robotic voice.

"Shit, shit, shit" Misty silently screamed trying to turn it off. How stupid, it was already on mute and she turned the audio back on. A light gurgling sound made her head snap to attention. The pokemon, no it might not be, this creature whatever it is was turning toward the pillar more tentacles slithering into the area. Misty stepped back but felt her pokedex get yanked out of her hands. It rolled around in the tentacle before the creature laid it down on a nearby boulder. The light the pokedex gave off wasn't enough to make out details but Misty shrank back as she saw the large silhouette move around the pillar.

The body was large and was a couple dozen feet long, but it curved like it had bones in it. There was some kind of round head but no neck. From out of those sides came too many tentacles to count. Many were on the floor holding the creature up, but as a section of it lifted itself up several were now freely moving in the air and inching towards her.

Misty reached for a shark rock to defend herself but tentacles shot out and wrapped around her wrists keeping her arms up. It pushed her back until it held her against the wall of the cave. Misty was terrified, a part of her yearning to be used, but most of her afraid to be eaten.

"P-Please don't hurt m-me" she struggled to say. "I'm sorry for being in your home… I-I" Misty trailed off unsure if it could even understand her like pokemon can.

There was a long pause as the creature had stopped making aggressive gurgles and the only movement from it was a few tentacles in the back waving around. The ones around Misty's wrists kept her arms against the wall on either side of her head still but their grip loosened a little. She thought she saw its head move down a little as if looking lower from her. She looked down and saw the wet spot on her shorts, it noticed that? A tentacle slithered forward on the ground and Misty tensed up, though she relaxed when it slowed down and raised up only a little to run along the side of her thigh, almost as if it was petting her.

"So… you don't want to hurt me then…" Misty said, looking at the creature. It's response was the most pleasant sounding gurgling it has done so far. Misty was still having those thoughts of being dominated behind her and those thoughts were coming more to the forefront as the creature looked to calm down itself.

All questions were answered when the tentacle on her leg moved over and pushed against her crotch up to her butt and began dragging itself back and forth against her. Misty gasped from the euphoric rush that instantly hit, she was so loud the creature stopped for a second making a sound as if it was a question.

"No I'm okay" Misty said, happy it actually cared at all. "Please keep going, that feels amazing".

No more words were needed as the tentacle went back to work grinding against Misty. She moaned through closed lips as the slimy juices of the tentacle dampened her shorts and her quivering vulva soaked her panties. This went on for a couple minutes before Misty felt a different shifting at her waist. Looking down through hazy eyes she saw a forth tentacle joined the third and they worked at undoing the button on her shorts. They struggled for a moment but before Misty offered to help the button came open and the creature made a light gargle of satisfaction. The zipper was dragged down and Misty felt her shorts get pulled down to her ankles where she willingly stepped out of them and the creature flung them away. Hopefully she'd be able to find those later.

Any concern about that was yanked away just like Misty's panties were being. She spread her bare legs wide, needing the creature inside of her, wanting those slimy juices all over her. The tentacle was gentle as it ran itself along the backside of her leg and around her clit. It felt nice, but Misty didn't want to be teased anymore.

"Fill me with your tentacles, I need it, please" she begged.

All consenting flesh was heavily lubed up already as the creature slid its appendage slowly up into Misty's core. The tentacle pushed itself in as far as it could go and slid almost all the day out before going up and back in. It did this a few times, loosening Misty up before spending some time part way in and wiggling around to rub against every inch of her insides. This motion made the redhead moan out loud.

The intense events dragged on as the creature penetrated Misty with a rhythm that made her body shake with lust. It watched her from a distance as it grumbled from pleasure too it seemed. Things were becoming a blur for Misty as her quim grew tight and hot. Her insides entrapped the tentacle as it continued moving in her, eventually slipping out giving way to the floodgates as Misty's orgasm overtook her. She could feel her essence mix with the slime and drip lengthily down her legs. That sweet scent filled the air now more than ever.

Misty's legs gave out and she went to fall but the tentacles on her wrist grew stronger again and lifted her back up holding her up. This creature was relentless and it drove her wild. The tentacle that was wet from her slithered back and it looked as if the creature sucked on it, taking Misty's flavor into itself which made her hot all over again.

Craving more Misty was happy to see two new tentacles slithering towards her, these seemed to come from the middle of the creature though all of them protruded out the sides so she could best assume it didn't have an actual penis, but perhaps all the tentacles could feel pleasure. Her left leg tingled as one appendage snaked it ways around and around going up until it rested on her asshole. The creature didn't rush, the tentacle teased her hole as it rubbed its slime over the area before poking lightly as if knocking on a door. Misty spread her legs as wide as they'd go still safely held up by her wrists.

"Oh yes, fuck my ass, use all my holes you naughty monster" Misty moaned, ecstasy taking her over.

Misty bent over slightly as the pain hit, the tentacle went in her ass inch by inch, trying to let her recover at each step. Her rectum fought back, clenching and relaxing over and over every time there was movement. Her body became distracted though as her pussy was filled by the other tentacle. As one hole worked with the movements of the creature's appendage, the other hole calmed and allowed entry to the other appendage.

"Mmm, ahhh, uhhh, ahhh" Misty moaned at the duel speeds of the extremities moving in and out of her. They pushed throughout her body, invading her and owning her. Misty panted hard as she was about to be sent over the edge. Her muscles on fire quaked for release once again each time the foreign flesh moved against them. Sensing she was close the creature sent out more tentacles, they grabbed onto her legs and lifted her up, pulling Misty towards the monstrosity. Some tentacles slid her top up and encased her breasts. Slimy tentacles trailed over Misty all while she was still being pounded in her nether regions.

A tentacle went around Misty's head, cutting off her vision, making this crazy bdsm situation even more sexy. He held onto the torso of the creature as she came again, riding out her waves the tentacles in her moved faster, trembling now themselves, before exploding, making Misty gasp as thick hot liquid, similar but also different from the slime, poured into her holes.

Even after the creature pulled itself out of Misty, she was grateful it continued to hold her for a minute or two while her body came down from the experience. Once she was back to normal, Misty collected her belongings. The creature held her shorts above her head for a moment, keeping them out of reach even when she jumped for them while laughing before handing them over.

Misty was dirty, sweaty, and covered in slime and who knows what else but she was in high spirits. Who cared if she didn't catch a rare pokemon, she got to experience something life altering. She felt so light emotionally, like she could handle just about any situation with more composure than usual. The creature gently wrapped a tentacle around her one hand and she walked alongside it as it slithered through the caves. They even ran into her bag thank goodness and she picked it back up.

They arrived at a way out of the caves and though the sky was signaling dusk Misty had enough light to head home. It was also nice the exit she was taken to was on the surface level so no more climbing was necessary. Misty walked out and noted the creature continued to hide itself from her, though she saw one dark purple tentacle wave bye to her.

"Thank you for showing me the way out" Misty said, smiling. "Oh and thanks for everything else as well haha. I'll be sure to visit you again, oh and maybe I could even get a friend to come by and see you. I'm sure she'd love meeting you too".

The creature gurgled in joy and slithered back into its home. Misty waved until she couldn't hear it anymore and headed back to her own home, pondering what story to tell her sisters about her lengthy time away. Oh well, her mind was in such high spirits Misty was sure something would come to her. In the meantime, she pulled out her phone and dialed.

"Hey May, it's Misty. Yeah hi! I've been doing really well actually. Listen, there's this cool new cave I found and it might have some pretty unique pokemon you might want to check out for your contests. Yeah it's really fun in there trust me".
