Symbiotic Relations

Spitfire sighed as she landed on the cliff face. It was a clear day and she had an early break from spring training. Perfect for getting away. Still in her flight suit she grabbed a bag of supplies she’d prepared earlier and took off.

Now just outside of Canterlot she had no regrets about her decision. She moved along the rock wall towards her destination: a small rocky opening she’d spied a few days earlier. It was hidden just behind one of the many waterfalls that fell from the mountain. She’d almost missed it had she not cut by it at just the right angle. Now she wanted to see what was inside.

She kept her svelte, athletic frame close to the wall as she inched her way closer, her wings just barely missing the rock. Soon she was just outside the cave and quietly slipped inside, getting a little doused by water in the process. But she was in.

Slicking her signature fiery haircut back, she scanned her environment and smiled. The cave was beautifully lit by glowing crystals of all colors. Embedded in the wall, fueled by the natural magic and energy contained within the mountain, they emitted every color imaginable. A mosaic of rainbows was scattered all about the walls of the cave. Even the small river that flowed out of the cave glowed a bright rainbow color. It was a truly magical place and Spitfire wanted to explore every bit of it.

“Now this is what I’m talking about,” she smiled to herself as began trekking through the passageway. The water felt refreshingly cool on her latex coated feet. She was very tempted to begin stripping it off right there and going in commando for the rest of the journey but decided against it. If she’d seen this cave it was more than likely someone else had spotted it to. And she certainly did not want to be caught naked in a random cave with a bag of mountain climbing and survival gear. Still though, she felt her body starting to get a little warmer under the material of the suit and was very tempted. She settled on pulling down the hood and unzipping the front for now.

She let out a sigh of contentment as she felt the cool air of the cave run over her chest. Now that she thought about it, she noticed a slight draft in the cave that blew cool air over her body as she moved through it. The air lightly caressing the inside of her cleavage was almost heavenly.

Soon she approached a fork in the cave. The light from the entrance was still visible so she figured here was a good a place as any. She removed a ball of yarn from her bag and hammer and stake. After threading one end of the yarn through she hammered the stake into the wall and tossed the ball into a small pouch outside her pack. Now she had a way out if she ever became lost. She continued on, following the river.

Little did she know that even deep inside the cave, she was not alone.
She continued onward, almost blissfully unaware of something stalking her. It remained hidden in whatever shadows it could find in the well-lit cavern. It scurried along the ceiling, staying high above her and out of her sight, watching and secretly scanning her from a far. In truth it had been hidden in the cave for years, waiting in near hibernation for something or someone to come along. Plenty of candidates had passed its way but it considered none of them.

Until now. It had never encountered such a perfect specimen before. This one, it could tell, was reasonably intelligent, certainly smarter than most of her species, athletic as well which was another desired trait, and above all moral. From a far it probed her mind, her experiences, her successes and her failures both professionally and personally. She had demonstrated the ability to learn from her experiences and remain ethical at the end. This one was perfect.

Spitfire began to feel the humidity in the air increase. Up ahead she could tell that the passage was coming to an end. She grinned and hurried along, her feet splashing in the water as she went. The tunnel gave way to a gigantic open area. The chamber was almost shaped like an arena, with a large pool of crystal clear water in the center being fed by several small waterfalls and rivers flowing into the room. Various smaller pools existed at various levels in the surrounding periphery. And the signature glowing crystals decorated the landscape.

She glanced downward. The ground was moist but not slimy. Inside there seemed to be nothing alive other than Spitfire herself. The cave was a beautiful work of art. She set down her bag.

“Awesome,” she grinned, “Now I’m really glad I decided to come here.”

Suddenly Spitfire noticed something. Down on the ground, in a pothole like crevice was a strange reflective liquid. Curiosity peaked, she moved closer to it. The closer she got the more she realized that it was not reflective but just black, blending in with the rocks. She knelt down by the stuff. It didn’t smell as far as she could tell and it wasn’t bubbling or steaming either. In fact, it wasn’t doing much of anything. It was oddly out of place in the paradise cavern.

Curiously, she dipped a few gloved fingers into it. It was a little thick as far as she could tell and stuck to her hands like a lightly watered down honey. She stuck her fingers together and pulled them apart, watching the stuff stretch and slide around her hands. She moved her hand to the rock to wipe them off.

That’s when it made its move.

The rest of the black liquid jumped up at her hand, joining the stuff already on her. Spitfire leapt back in surprise and panic but it was too late. The substance began sliding up her suit towards her shoulder. Panicking, she let out a scream and began scurrying away, waving her arm, trying to flick the stuff off of her. She tried pulling it off with her other hand but that only made things worse as it stuck to that too and continued upward. It reached her shoulders and found purchase. Her unzipped suit gave it a perfect entrance as it slipped into her suit. It slid over her breasts and moved under the latex, covering the rest of her body. Spitfire went rigid with shock as she felt the substance slid across her skin. It coated her chest and moved to her back, slipping over her shoulder blades and moving down to her wings. It dripped past her wing joints, giving them an unintentional slight massage before moving down to her perfectly rounded ass. Meanwhile, up front, the liquid slide down her abs and towards her crotch. It seeped through the small patch of pubic hair she had and moved down to her pussy, coating her outer lips before wrapping around her thighs and moving towards her feet. Soon her entire body was coated as the substance moved upwards towards her head. Spitfire sucked in air and sealed her mouth as she prepared to be coated but it never came. In fact, it stopped just below her ears and along her jawline.

She exhaled, forcing herself to take regular breaths, “Okay, Spitfire, just relax.”

She wasn’t dead like she expected nor was she being digested. She continued breathing, waiting for her panic to subside. Once she had calmed down the first thing she noticed was that she wasn’t exactly uncomfortable. Whatever had decided to coat her body was surprisingly warm, though not too hot. She also found she was still able to move, though she did so rather cautiously. She glanced down at her chest. She could still make out the outline of her firm breasts though it looked like she was coated in black oil. Whatever had decided to take her over clearly wasn’t interested in eating or harming her. Carefully, Spitfire tried to stand up. Slowly but surely she made it to her feet. She tried to take a step and instantly collapsed. A vibration, originating right between her legs ran through her body, taking away her legs’ ability or desire to stand and sending a pleasant tingling sensation through her body.

“Hah,” she gasped, “What was that?”

She poked the substance. It remained unreactive. Slowly she tried moving again, this time crawling. Once again she met a similar answer and stopped.

“Okay,” she said glancing down at her chest, “Clearly you don’t want me going anywhere.”

She leaned up against a rock which she found to be surprisingly comfortable.

Spitfire sighed, “So what do you want with me?”

Almost on cue, she felt the liquid begin to move. It began to concentrate around her chest while still keeping her body coated. She felt a tightening around her nipples as a series of odd contractions began. The liquid began to tug and pinch her nips, sending pleasant little shocks down her body.

“Ooh, okay,” Spitfire giggled, “Soo, uh, while this isn’t exactly unwelcome I would appreciate it I could get a little explanation.”

The vibrations resumed, this time concentrated around her breasts.

“Uhh, never mind, just keep going on with this,” Spitfire moaned.

While the substance continued to tug and massage her breasts, Spitfire felt herself starting to get a little hot below the surface. Her arousal began to increase until a hot blush burst across her face and she began to moan as the substance continued to massage her breasts. A small part of Spitfire’s mind was still concerned as to what was happening to her but the rest of her pushed it to the back. Whatever had bonded itself to her clearly wasn’t interested in harming her, quite the opposite in fact. Soon she began to feel a tugging sensation along her clit. It pinched and tugged at her button as her breast massage continued on.

“Oh yes! Just like that,” she moaned closing her eyes. She began to spread of legs, giving the substance marginally better access to her nethers considering they were coated in the stuff. Her hands moved up and she began to strip her Wonderbolts flight suit off of her, revealing just how much she was coated. Her arms and shoulders and hands were all colored black as she pried off the top of her suit. One hand moved to join the liquid as it massaged her tits while the other moved down to rub her clit. Soon she felt more vibrations along her lower lips and her eyes flew open. Electric tingles shot through her body as her lips and inner thighs began to vibrate along with the fluid.

“Ugh… Holy shit, yes!” she moaned. She struggled to remove the rest of the suit from her body. Whatever this thing was, it was relentless, never stopping and never resting, making removing the rest of her suit a challenge but a pleasurable one none the less. With a moan and a kick of a black coated foot she managed to remove the suit from her body, kicking it into one of the many pools before falling back and continuing her arias with a wide smile across her face.

Her feet began to feel cool, causing her open her eyes. The fluid began to move up her legs and coalescing by her thighs, leaving her lower legs uncovered. A similar process was happening with her arms as the liquid migrated towards her thighs. A bulge began to form as the fluid slid to an area between her thighs and began to mass. A large ball, connected by streams of black formed just below her entrance. Spitfire glanced down in excitement, watching as it began to form a sort of prehensile tentacle. Soon it had fully formed and began to wiggle and flex. And above all, it was large…

“Oh fuck me,” Spitfire moaned as she felt the slime begin to spread her lower lips.
The tentacle wasted no time and thrust forward into Spitfire’s still coated pussy. Spitfire threw her head back as her walls parted to the intruder. With the liquid itself penetrating her, there was little need for Spitfire’s juices, though that didn’t stop her from making them. She moaned as the tentacle wriggled its way deeper into her body. She stayed openmouthed and wide eyed as she felt every movement of the tentacle. It halted just outsider the entrance to her womb and began to slowly pull itself out.

"Hah!” Spitfire breathed as she felt the object slowly leave her body, it purposely reshaping itself as to drag as much of its surface across her walls as it could. Once it was just barely inside of her, it stopped before slowly inserting itself into her once again. Spitfire began to feel little bumps forming along the top as it dragged across her G-spot.

“Oh fuck yes!” she moaned, as her first orgasm of the day rushed through her body like hurricane, sending pure pleasure all throughout her body. She felt herself trembling as her orgasm slowly began to subside.

Once again, it stopped just outsider her womb before pulling back out and thrusting in, increasing its speed and force each time. Soon the cave was filled with the sounds of Spitfire moaning and the squelching of fluids as the Wonderbolt was pounded. Spitfire continued to play with her breasts as the tentacle relentlessly fucked her.

Suddenly she felt something prod at her rear entrance. She glanced downward just in time to see a smaller tentacle jam its way into her anus. Spitfire moaned again as her ass was violated just as the one in her pussy pulled itself out. One went in, the other went out, making sure Spitfire always had a tentacle inside of her, all while continuing to play with her boobs. Back and forth the tentacles moved as they continued to relentlessly fuck Spitfire’s body.

“Uhhhhhhh,” Spitfire sighed as her moans devolved into animalistic grunts of ecstasy.

This continued on for hours as Spitfire was fucked to orgasm after mind numbing orgasm, until they all seemed to blend together in one continuous stream of pleasure. She could have sworn that she felt every ridge and bump along the edge of the appendage every time it slipped into her. The tentacles never stopped or rested between them and soon Spitfire’s body was limp, her legs spread apart, her arms flopped over by her sides and her tongue lolling out of her mouth, leaving a puddle of drool along her chest and the ground. For a while, she almost forgot about the alien liquid holding her hostage. All that mattered was that she was receiving the fucking her of her life and she was loving every second of it.

The tentacles began to speed up. This roused the Wonderbolt from her near pleasure coma as she raised her head up and glanced downward. The force of their thrusts also increased, making Spitfire feel as if she was experiencing her own personal earthquake.

“Uhhh, yeah, yeah, yeah!” She moaned as she was brought to her strongest orgasm of what was now the night, “Oooh fuck me! Fuck harder you black alien snot!”

The tentacles obliged and with a final series of monster thrusts, they brought the athlete to the heights of ecstasy once again. This time though, they didn’t pull out. The one in her pussy continued on, slipping comfortably past her cervix and splashing across her womb.
Spitfire’s eyes flew wide open as her mouth formed an O as she felt a warm substance filling her up. The liquid continued to pour inside of her until she saw a slight bulge form on her stomach. The liquid retreated from her twitching pussy and began to slide itself up into her ass. Spitfire once again moaned as she felt the strange substance slip up past her anus, into her rectum and then up farther inside of her. As she felt the last of it slip up into her body, she slumped down on the rocks, utterly spent and completely exhausted. Occasionally she felt her pussy lips or asshole twitch as she came down from her sexual high.

She remained on her back with her legs spread, until she could once again move. It was the most undignified position she could think to be found it, naked and twitching on the floor of a cave after the fucking of her life, drooling all over herself and giggling like an idiot. But still, she wouldn’t even have cared even if Princess Celestia herself walked in on her, basking in the afterglow of nearly a hundred orgasms.

Once she was able to move she sat up and glanced down at her stomach. Though just barely noticeable, there was a slight bulge along her stomach, indicating where part of the substance resided inside of her. She poked her stomach and giggled at the slight tickling sensation as she felt the liquid slosh around inside of her.

“What the hell are you?” She grinned.

In your language, my people’s name is the Klyntar. A voice echoed through Spitfire’s head.

She gasped, “Whoa, what is this?”

Forgive me, came the reply, My species can communicate telepathically with other races like yours. It can be a little jarring at first but I promise you will get used to it.

“Okay, okay, wait a minute, you’re in my head?”

Well, if you would like to put it that way, yes I am in your head. And in a few other places. The voice replied, sloshing inside of Spitfire’s womb for emphasis.

Spitfire laughed, “Okay, okay, you’ve made your point. So, uh, I suppose we better get this awkward question out of the way, why’d you-”

Initiate sexual contact with you? It is how my race bonds with potential hosts. I suppose this will help you understand, my race is also known as Symbiotes. We form symbiotic relationships with hosts of good physical and moral standing, giving the hosts enhanced abilities and in return we feed off of the host’s adrenaline and other hormones. You happened to be passing through here and reawakened me from hibernation. You were the best host I had seen in centuries so I took the opportunity. Forgive me if it was a little sudden or jarring.
She grinned, “Oh, I’d say it wasn’t too bad once I got into it.”

I’m glad you enjoyed yourself. The voice seemed genuinely pleased.

“So do you have a name or am I going to have to keep calling you ‘the black sex slime that invaded my insides?’”

No, no, no, I do have name. In your language, my name would be Katana.

“Katana? Well that’s certainly interesting. Nice to meet you, I guess. I'm Spitfire.”

A pleasure to meet you too, Spitfire.

“So, uh, am I your host now?”

If you so desire. Normally I would have taken the time to ask but I was very close to starvation. If you would like I will leave your body.

“No! No! Heaven’s no! Not after sex like that. I’ll be your host if I have that to look forward to,” she grinned.

Thank you, Spitfire. I’m in your debt.

“Don’t sweat it.”

Spitfire finally regained the strength to stand and stumbled over to where she had discarded her flight suit.

Here, let me help you with that.

Instantly, she felt rejuvenated. Her strength and stamina all returned to her making her feel like she could fly a thousand miles then go a thousand more. She felt great! Better than great in fact.

“Sweet Celestia, that’s nice.”

One of the added benefits of having a Symbiote. I understand your species has the ability to fly.

“Yeah,” she said pulling on the latex uniform and retrieving her bag.

Well allow me to demonstrate something for you. Can you go to the entrance of the cave where you entered?

“Uh, yeah, sure.”

A few minutes later, Spitfire was standing in front of the waterfall where her ‘ordeal’ had begun. The sun had gone down leaving only the moon, the stars, and Cloudsdale to illuminate the night.

“Now what?”

This.

Spitfire gasped as she felt Katana slide out of her body and into her suit once again. She felt him slide up her skin until the entire inside of the suit was coated again. The liquid in her womb reformed into a limb and slid out of her tunnel, regrouping with the rest of the Symbiote’s body, through remaining comfortably, for both parties, inside of Spitfire’s pussy.

Next something strange began to happen. Spitfire’s suit slowly began to turn black as Katana merged with the material. The Wonderbolt’s logo turned white while her once sky blue uniform was now black as the night. Spitfire’s hood slide into place over her head, only this time it came with a full black face mask with the only face like features being a pair of large, white, feathered eyes.

She felt more of Katana slide up into her hair, merging with that as well and turning it a deep purple color. She grinned and noticed a new sharpness of her canines.

Ready for round two?

Her grin widened, “Who do you think I am? I was born ready.”

With a running start, she dove through the falls and into the now black night. Out among the darkness she shrieked with laughter as she sped through the clouds, like a shade in the night…
