Spitfire

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…

Fleetfoot

“Hey Soarin’,” Fleetfoot asked, “Have you noticed anything different about Spitfire?”

Soarin’ finished drinking his soda and tossed the can, “No, why?”

“I don’t know. Something just seems a little different about her.”

“She’s probably just in heat or something, let it be.”

Suddenly a flame haired Wonderbolt bounced into the cafeteria. Instantly she spotted Fleetfoot and flashed a toothy grin.

“Oh Celestia here she comes.”

“Hey Fleetfoot!” Spitfire grinned.

“Yeah?” Fleetfoot asked, slightly cautious.

“There’s something cool I gotta tell you.”

Fleetfoot flashed a glare at Soarin’.

Fleetfoot took note to remind herself that if she ever got out of this situation alive, she’d tear Spitfire a new one for telling her to come here, assuming she made it out of this cave alive that is.

The black substance smooth like a liquid latex as it hoisted her towards the ceiling. All four of the Wonderbolt’s limbs were bound by the substance as she was transported further into the cave. Soon she was inside a large empty arena like chamber. Various pools all decorated a larger lake at the center of the chamber, all of them containing a familiar black liquid.

Fleetfoot began to struggle, “Oh no! Oh no no no no no no no.”

The substance holding her paid no heed as she was transported along towards the center of the chamber.

“No! Let me go!” she shouted, fighting against her restraints.

An appendage began to form from the liquid mass above her. It lowered down towards her face.

“No! Get away from me!”

A puff of white gas burst from the appendage. Fleetfoot’s eyes rolled up into her head and she fell silent, her body going limp a few seconds later.

When the wonderbolt awoke, she was pleasantly surprised to find that she wasn’t dead. Only she couldn’t quite remember why she expected to be dead to begin with. Her mind was slightly foggy, like she was caught in the area just before one falls asleep at night. She took a moment to examine her situation. She was in a cave, being suspended from the ceiling by thick black appendages that were gently lowering her towards a dark pool below her. And she was naked.

She wasn’t exactly sure why or how she ended up where she was. A cool draft ran over her nude form causing her to shiver slightly. She glanced down at her body. She hadn’t even realized how wet she was. Oh well…

Below her the black surface was shaping to meet her, it forming into a soft black seat below her as she was placed into it. It felt soft on her skin and surprisingly warm. It felt like she was lying on the surface of a giant bowl of pudding that refused to allow her to sink further into it. The tentacles holding her legs released her as two more rose up below her and pulled her down into the chair in a reclined position. Her arms were pulled up above her head. Overall, she found that she wasn’t too uncomfortable. Though her arms and legs were restrained, they weren’t painfully so. Just enough so that the athletic girl knew that she wasn’t going anywhere anytime soon.

Suddenly her seat began to move. Fleetfoot, still hazy, could only watch as her legs were slowly spread apart as more of her chair rose up to conform to the shape of her body. Something was happening.

From the pool below her, a small tendril rose up between her legs. Fleetfoot glanced down at it with some curiosity. It was about the same thickness as her tongue and moved carefully and deliberately, lightly trailing along the inside of her thighs, leaving a slightly oily black trail as it went. Fleetfoot felt the lubricated areas begin to warm as a heat began to radiate through her body. She panted slightly as the tendril approached her slit.

It lightly began to tease her outer lips, exuding more of its lubrication as it swirled around her entrance, mercilessly teasing the wonderbolt.

“Oh yesss…” Fleetfoot moaned, her eyes closing in delight as her nipples began to rise.

Two more tendrils rose up on either side of her, arching over towards her until they hovered over her pert breasts. They began to drip more of fluid onto her body until they were almost pouring it onto her. Fleetfoot looked up in anticipation before the tendrils began to lower and slowly began to massage the liquid into her skin. The tentacles swirled around her breasts in a continuous pattern, getting ever so close to her peaks before backing off and continuing the delightful torture again. Fleetfoot could only moan in pleasure as the tendrils continued their work.

While Fleetfoot enjoyed the best boob action she’s received in years, the tendril between her legs began to move towards her entrance again. It began to reshape itself to have a more feathered tip as it began to slowly lick at the entrance to her slit, going up and down ever so slowly as to maximize the wonderbolt’s pleasure.

Fleetfoot gasped at this contact as the tentacles at her chest continued their massage. Less than a second later, the gel coated tentacle probed at her entrance, beginning a slow probing, teasing, tongue like motion.

Fleetfoot’s eyes flew open, “Oh fuck…”

The tentacle was a perfect fit as it wiggled around, just barely inside the wonderbolt, causing her to squirm and curl her toes and attempt to spread her legs further to grant it better access.

“Don’t fucking stop,” Fleetfoot sighed with content.

A second, smaller tentacle emerged and began to aim itself towards her mons. The tip formed a small suction cup like shape before it dove down at Fleetfoot’s clit. Fleetfoot gasped as the tiny feeler found its target and latched firmly onto her clit before slowly initiating a sucking/tugging motion in rhythm with the probe inside of her.

Fleetfoot let out a sigh as the appendage alternated between lightly probing her entrance to circling around, taking its time to ensure that its prey stayed as content as possible. Its own aphrodisiac lubrications mixed in with Fleetfoot’s own juices as her hole began to spasm with anticipation.

Suddenly the tendril shot forward into her slit just as Fleetfoot’s walls clamped down upon it as it began to snake its way inside her. Fleetfoot bit her lip as she felt more of the appendage slip ever so slowly into her, it releasing more its arousing nectar as it went. Finally with one final thrust it bottomed out inside the wonderbolt, just at the entrance to her womb.

“Hah, oh fuck,” Fleetfoot moaned as a hot blush spread across her face, contrasting with the white of her hair.

The tendril finished settling into its new environment before the tip began to explore. Like before it began to circle around, ticking as many sensitive zones as it could find before alternating to a probing routine, poking at her cervix.

“Oh… that feels good,” she groaned as she settled further into her seat.

Meanwhile the tendrils at her chest began to change, their tips extending into conical shapes. A closer inspection revealed almost lip like suckers on the inside. Caught up in the action between her legs, Fleetfoot didn’t have time to notice the two suckers latch on to her nipples and begin to lightly tug at her breasts.

Her eyes flew open as she felt two pairs of lips begin to suck at her B-cup breasts. While they weren’t as big as Spitfire’s, Fleetfoot could definitely tell that the tentacles couldn’t care less as they gently pulled away at her peaks.

The tentacle inside of her meanwhile halted its probing at her womb and began to rotate as it slowly pulled itself out of her, swirling its length around inside of her, purposefully teasing and tickling her as it searched for as many sensitive spots as it could find.

Almost as it was about to pull out of her it found one. A slightly rough area on the ceiling of her tunnel made the tentacle pause as the tip brushed over it, eliciting a squeal of delight from Fleetfoot.

“Hah! Oh fuck…” Fleetfoot gasped, her mind now glazed over with lust, “Oh that felt good…”

Once it had almost pulled itself out of her, it began to reshape itself. A series of bumps began to form all along the top and sides of the tentacle as two smaller ones joined it. The new appendages were about the thickness of a finger and began to wrap around their larger neighbor before all three plunged into the wonderbolt.

“Hah!” Fleetfoot gasped, “Oh yes…”

The larger tentacle began to get a good soft rhythm going as it thrust inside her vagina, taking care to make sure as many of its bumps grazed over her G-spot before rotating as it pulled out and continuing.

“Ahhh… oh that feels good.”

Meanwhile, the two smaller tentacles began their own work. One joined the larger tendril as it swirled over and tickled any areas its brother missed while the other began to lightly poke away at the entrance of Fleetfoot’s womb, squirting more of its arousing lubricant over the entrance before lightly rubbing it into the tissue and continuing to caress the region.
Fleetfoot’s body hung limp in her seat as pleasure spread across her body like a wave. With each thrust of the tentacle, her arousal increased, building up inside of her. Her breathing became fast and erratic.

Her mouth hung open and her tongue lolled out of it as she began to droll all over herself with each pant that left her. She moaned softly and sensually as the tentacles probed and teased away at her pussy. The muscles of her walls instinctively began to clamp down on the squirming, slippery invaders.

"Ooohhhh yessssss…” Fleetfoot moaned, mixing her primal groans of pleasure with obscene squelching of the probing tentacles as they continued their sinful routine for almost an hour.

Soon they began to slow to a gentle crawl as a fourth tentacle joined the mix. Fleetfoot, who’d resided to happily sighing in contentment every few minutes as the tentacles in her nethers grinded against her, didn’t notice the fourth invader as it aimed itself towards her asshole.
By now, her pubic region was coated in a slime of her own fluids and the lubrications of the tentacles so the fourth tendril didn’t need to prepare long.

Fleetfoot’s eyes opened as she felt a light poking sensation at her rear. She’d never had anything inside there before but for some reason she now felt okay with it. She glance down, half in curiosity half in excitement as the small intruder pushed its way inside her anus and into her rectum. Once inside it began to trail itself along her walls, lightly brushing up against any sensitive spot it could find before curving upward and around, plunging deeper into the wonderbolt.

Fleetfoot blinked as she began to feel something strange. The tentacle in her ass was expanding. Ever so slowly its diameter began to increase from the thickness of a pinky to a thumb to now Fleetfoot swore it felt like she had a cock inside of her. She felt the portion in her rectum begin to expand until a large part of it was brushing up against her walls. All while further up, the tendril continued to explore.

Suddenly, the large blub in her ass began to rotate, emanating fluid as it went, coating the walls of her chamber. Soon it established a back and forth like motion, rotating one way before reversing and going the other. Fleetfoot’s eyes were wide. It felt so oddly bizarre and yet so erotic at the same time. While it certainly felt weird, she couldn’t deny that it felt so strangely good as well. All while she felt the occasional poke deeper inside her as the tentacle continued to probe. She settled back in to her chair as the tentacles in her pussy resumed their thrusting with renewed vigor.

“Uuuhhhhh yeah,” Fleetfoot grinned, “I could stay like this for quite a while…”

Fortunately for her, the black mass supporting her and the tentacles probing her agreed. After another hour of this gentle probing, the tentacles seemed to decide that it was time for the main event. They had kept the wonderbolt aroused and content with pleasure but also kept her out of reach of the precious release that her body was beginning to crave more and more. Fleetfoot herself was just barely becoming aware of how slightly unsatisfied she was feeling. Sure she wouldn’t deny that the attention she’d gotten was wonderful but just… something seemed missing.

Suddenly she felt the tentacles in her pussy begin to retract out of her. This time they pulled all the way out of her body and disappeared into the black pool below. After the hours of attention she’d been receiving, she suddenly felt empty. She didn’t have to despair for long as a larger, thicker tentacle appeared between her legs. This one was thicker than the other three all put together and was certainly larger than any cock she’d ever seen before in her life. It was easily approaching 7 centimeters in diameter and was probably a little bigger with all the bumps and bulbs all along its length. The tip was slightly tapered and the whole length glistened with fluid.

“Whoa,” Fleetfoot giggled, “You’re pretty big. I hope you’re as good as your friends here because I- Oh!”

She was cut off as the tendril lunged forward and quickly embedded itself inside of her. Fleetfoot jerked lightly as the end bumped her cervix. Her walls instantly began clamping down on the intruder, finding it slightly difficult with all the bumps and lubrication that came with it. It remained still inside of her for a few seconds before it began to rotate and slowly pull out of her. Once the taper tipped was just barely inside of her it began to slowly thrust forward, its rate of rotation slowly increasing.

Fleetfoot arched her back towards the ceiling and her mouth opened to form a perfect O. The speed of its thrusts also began to increase. Each thrust lightly knocked at the entrance to her womb while the bumps all along the length of the tentacle brushed over her walls, dealing special attention to her G-spot.

Soon the Fleetfoot’s sinful arias resumed as she let out guttural moans of pleasure with each thrust. Her walls were comfortably stretched to their limit as the tentacle swirled inside of her. Her body, try as it might, could not get the grip it wanted on the invader as it spun and rotated inside of her.

Suddenly it began to try something new. With each thrust it let out a pulse of vibration. As the speed of the thrusts increased so too did the frequency of the vibrations. Each thrust rocked Fleetfoot to her core, like someone had placed a heavy bass speaker inside her. Her whole body pulsed with the vibrations. Fleetfoot glanced down and happily watched as her stomach shook with each thrust of the tentacle, a small bulge visible each time it entered.

“Oooooohhhhhh yesssssssss,” she hissed, “Doooon’t…. stop…”

Suddenly her eyes flew open in a panic. She felt something at the base of her stomach. There it was again, this time it was moving! It was at the back of her throat now. It felt like something was making its way up her throat. She almost felt like she was throwing up without the normal accompanying burn. She began to gag before suddenly a black tendril emerged from her mouth. It was still coated with lubrication as it slipped out her throat and into the air above her head. Strangely, it tasted sweet of strawberry with a hint of vanilla. It could have been Fleetfoot’s imagination or very well just the flavor of the lubrication but right now Fleetfoot was slightly panicking. Thankfully she found that she could breathe through her nose, abet with slightly more difficulty though certainly nothing unmanageable. She was almost able to ignore the thrusting between her legs for the moment as the tendril emerging from her throat began to arch itself down towards her chest.

It began to split off into two more separate tentacles that each snaked their way down between her breasts before both curled back upwards and began to wrap around her sensitive globes. They lightly began to squeeze and release her breasts in time the thrusts in her nethers.

Fleetfoot soon decided that this wasn’t so bad. It certainly was the strangest thing she’d experienced though that was strongly overshadowed by the fact that this was the most pleasure she’d felt in a very long time, potentially in her entire life. She moaned around the tentacle and closed her eyes as she fell back in to the hazy lust around her.

This was easily the best fucking of her life. She could only moan in delight around the tentacle now as it continued to kneed away at her breasts while the tentacle in her pussy had reached almost jackhammer like pace. Her entire lower half was shaking through a combination of the vibrations and the thrusting as well as Fleetfoot’s own inability to control herself anymore.

Like a puppet she ground her body to the rhythm of the undulating tentacles invading her holes. Her body danced in response to the movements of the black tentacles as she began to approach what would easily be the greatest climax of her life.

She felt so naughty. Just being here, in the grasp of this black slime, she felt like the dirtiest girl in the world, experiencing sensations no one in their right mind had any right to be feeling. She felt so sinful, almost like she was stealing pleasure from the gods themselves.

Finally she began to approach her coveted release. The tendrils did nothing to stop as they continued on with superhuman stamina, never slowing or skipping as they went. Finally, with one final thrust it happened.

Fleetfoot screamed into the tentacle in her mouth and her eyes slammed shut so hard that she saw stars. Her walls clamped down on the tentacles inside her only to find that only made the pleasure stronger. Like a tsunami crashing into the tallest cliffs imaginable, Fleetfoot’s climax came. Her entire body convulsed like she was possessed as she rode out wave after wave of the most powerful orgasm she’d ever experienced in her life. Her mind had gone completely blank as the orgasm began to die down and her brain slowly began to reboot itself. Only something was wrong. She didn’t feel satisfied at all. Not even close. Not by a longshot did she feel spent. In fact she felt like she could keep going for days if she wanted. She half expected the tentacles to stop only to be pleasantly surprised to find that they had continued their thrusting all through her climax and had not stopped at all since then. Fleetfoot grinned as best she could. She could tell she was going to like this.

Many hours and equally many orgasms later Fleetfoot was still up and kicking. She had no idea what was in the liquid that emanated from the tentacles but she was sure that it was why she hadn’t blacked out of died of dehydration yet. In fact she felt better than she ever had before. She felt another powerful orgasm upon her and smiled. Good. This one would make 15. Or was it 16? 23, it was probably 23 she decided.

This time however, things would be different. Out of the corner of her eye she saw a mass moving up the tentacle in her pussy. The mass moved closer and closer to her entrance before slipping inside. Fleetfoot gasped as another powerful orgasm hit her body. This time, the tentacle joined her. It pushed its tip up to her cervix and lightly pushed into her womb, just as the large mass slide down the tendril and into her body. Fleetfoot’s eyes shot open, even through her orgasm as she felt a hot liquid be deposited inside of her. It felt vaguely sticky as it seemed to cling to her walls before sliding down to congeal in a pool inside of her. She had no idea what it was but she knew one thing, she needed more of inside her immediately.

This time the tentacle in her pussy pulled out, utterly spent, before disappearing into the black pool below her. Fleetfoot let out a whine of disapproval before opening her eyes and glancing around her. All around her, more tendrils began to rise out of the pool and form a line between her legs. Each one looked different in some respect with various bumps and patterns all along their surface. Fleetfoot stared wide eyed at the procession. Slowly the one at the front moved towards her red puffy lower lips and began to take its position.

Oh fuck me, Fleetfoot thought.

“Hey, anyone seen Fleetfoot?” Soarin’ asked.

Spitfire looked up from her drink and pulled down her sunglasses. She’d been spending awful lot of time in that new black suit of hers…

“She said she was going on a hike and might not be back for a few days,” she said with a grin. Were her teeth sharper?

“But that was two days ago.”

Spitfire shrugged with a grin, “Hey, let her take all the time she needs. If she’s not back in a week then I’ll go look for her myself.”

“Alright…” Soarin’ said, not quite believing her but accepting her story.

Suddenly Spitfire perked up, “Hey Soarin’!”

“Yeah?” he asked cautiously.

“Did I ever tell you about this weird cave I found?”

Deep under the mountains, inside a certain chamber of a certain cave, Fleetfoot lay limp. The symbiote sighed internally. Tachi knew she went a little too far with this one but hey! She wanted to have some fun with the others after all these years of boredom and if her new host was perfectly willing to go along with it? So much the better. Still though, she’d yet to bond with her new host yet despite all the fun she’d been having with her. Oh well, that was today and hopefully the next few days would be for. Tachi smiled internally. This one was going to be fun…

Up above the large black pool, Fleetfoot’s unconscious form began to lower. The black liquid of the pool rose up to meet her. Her body began to be coated black as she floated on the surface of the liquid before she slowly began to sink into the ocean of oily blackness below her. First her legs, then her thighs, then her torso and arms until finally nothing but her head and her white hair remained above the surface. Tachi stirred beneath it. She found the wonderbolt’s hair to be quite beautiful with its color. She decided that, at least for the next few days, she would change that. Slowly the remainder of Fleetfoot’s body began to sink as well until her head disappeared below. While to anyone on the surface the pool appeared to be inactive, below Fleetfoot was being willfully violated in ways she hadn’t thought possible, much to her and the population of symbiotes enjoyment…
