Fluttershy squeezed her eyes shut, trying to force out the images of whatever nightmare she had just been having. The dream had been strange, as she had imagined her and her friends wandering through the forest in search of a tower where Twilight was supposedly waiting, and then after that… Fluttershy didn't even want to think about what happened when they had found the tower.

She reached down in order to pull a blanket up over herself only to find she was not in her bed. The mare looked around nervously, her eyes going wide when she realized just how far from home she truly was.

All around her was a great lake of black viscous liquid that clung to her fur and filled the room completely. She couldn't tell where the light for the room was coming from as she saw no torches or magical light sources, but that was hardly her concern right now.

Looking down, she recoiled in terror, noticing that her hooves were completely submerged in the strange black liquid. With a startled gasp she tried to pull them out, only to find that the black liquid clung to her tightly, making it difficult to move. After a short struggle, she managed to lift a hoof almost completely out, only to find herself in an odd position.

With her one hoof free she no longer had the leverage to lift any of the others and her wings simply did not have the strength to lift her from the clinging muck. With a sigh of defeat, she let her hoof fall back into the liquid, noting how it almost seemed to reach up, anticipating her action and swallowing her hoof.

She shuddered in fear but forced herself to focus, she and her friends had been through terrible circumstances like this before, though now that she thought about it, nothing had been quite this disturbing. “H-hello.” She whispered, looking around, having only just realized she hadn't tried calling out, though she suspected it would be a useless action.

When no answer came she glanced over to the closest wall, figuring it might be able to at least help get her out of this creepy black goop and give her the leverage she needed.

Walking was a slow and arduous task, one that took several minutes to do just to get a foot away, at the end of which Fluttershy sighed, nearly collapsing from the sheer exertion. The liquid seemed to be fighting her with each motion she attempted and though the pegasus was stronger then what some might think, she did not have the endurance to fight back against such a strange and resilient enemy.

Using her wings to keep her from collapsing, Fluttershy looked around once more. “Is anypony there?” She yelled, louder than the last time.

When her question was met with the unrelenting sound of silence, she sighed in defeat.

What would Rainbow Dash do? She thought to herself, wondering just how the prismatic pony was doing right now.

She probably already escaped. Fluttershy remarked rather glumly, imaging her friend busting through a wall and flying to safety.

She knew bravery and ingenuity would be what saved her in this situation, but for the life of her, she couldn't think of anything she could do. The ground, floors and roof felt and or looked like stone, but the goo was so sticky as to make movement nearly completely impossible. The liquid itself was extremely resistant to force, not even reacting when Fluttershy pulled a hoof out and punched it. Not like Fluttershy actually believed she was going to punch her way out of this situation anyway, and she doubted even Applejack could accomplish such a feat.

Pursing her lips, the mare wondered just how much air she had left, as there didn't seem to be a way out of the room or any windows to speak of. Though a spike of panic shot through her she forced that emotion down, her experience in dealing with such danger at war with her shy, and easily startled nature.

With a gulp, the pegasus closed her eyes and listened, remembering something she had read about caves and buildings revealing the exit based on the movement of the air. When no wind brushed across her feathers and no sound met her ears she frowned, barely resisting the urge to slump to the floor in defeat.

“Can anypony hear me?” She yelled.

When no answer came she sighed again, only this time she forget to resist the urge to flop to the ground in defeat.

Her body impacted the thick, viscous fluid, and though her eyes shot open and she tried to pull back, she found herself stuck. Panic surged through the mare, and as she tugged and pulled the goo resisted, holding her fast, pulling her down. The black liquid crested the halfway point of her barrel and continued to crawl upward, threatening to cover her entire torso in it's strange and disturbing form.

Planting all four hooves on the ground, Fluttershy pushed, heaving her weight against the goo, and flapping her wings in a desperate bid to free herself. For a moment it seemed as though victory was only a second away, then all at once, the goo seemed to gain a mind of its own, and thick tendrils of inky blackness sprouted from the liquid flowing around her. Each appendage crawled up the mare’s side, a startled shriek tearing from her throat. With renewed intensity she fought, flapping her wings and pushing her legs with every ounce of strength she had.

Again she seemed seconds from being free and again that hope was dashed, this time by something heavy hitting the back of her knees, knocking the strength from her limbs and causing the goo to surge up her sides. Her barrel was encased completely and by the time she screamed, it had crawled all the way up to her neck, encasing her tail, back, limbs completely. Her wings followed suit, becoming pinned to her back, pulled down by thin strands of black liquid that draped over her form.

“Help!” She cried, limbs flailing as wings tried to flap.

Alas, no help came, and no amount of flapping or struggling was able to free her of the strange liquid’s foul clutches. As the seconds ticked by the mare found herself pulled further and further into the liquid, making escape utterly impossible. The floor she had thought she had felt was no longer there, vanishing mysteriously, only to notice that the floor had not gone anywhere. Instead, the goo rose from the ground, pooling around her and extending all the way up to her chin.

Tears crawled down her cheeks and the mare clenched her eyes shut tightly, praying to whatever deity that would listen that it would at least be quick and if she was lucky, painless. Yet the mare did not feel the cruel touch of lash or blade, and though the goo clung to her tightly, it had stopped moving.

Opening her eyes the mare looked around as best she could. All around her the black liquid had drawn its mass around her, leaving her half floating in it. Maybe this was some sort of creature? There had to be an intelligence at work after all, and though the liquid clung to every part of her body, she did not feel it press against her particularly firmly.

“Hello, mister goo monster sir? Could you maybe stop please.” She whimpered. “I don't want any more hugs.”

The liquid gurgled and popped in a crude facsimile of a laugh, making Fluttershy gulp. “P-please?” She asked hesitantly.

The goo churned suddenly, something thick suddenly pressing against the entrance to her pussy, drawing a startled scream from the pegasus. “No, please, stop!” She cried.

The creature ignored her cries of terror, tuning out the ensuring screams and tears coming from the helpless mare. The thick appendage pressed inside her, slipping past the meager defense she put up and surging deep into her body. Fluttershy could feel the slippery appendage penetrate her completely, the slimy length filling her body to a degree she had never experienced before.

It didn't take long for more and more of the foul black liquid to pour into her pussy, filling every nook and cranny of her body with it's writhing length. She thrashed her limbs, kicked her hooves, flapped her wings but nothing could dislodge the goo, or even moved her an inch. It was obvious that she was stuck fast, and no amount of power she could muster could free her. Stifling her cries the mare tried to squeeze down on the liquid still flowing inside her, trying to push it out.

The goo writhed suddenly, seemingly enjoying the resistance she was putting up, and pumping more and more of itself into her until her pussy was so full that the mare could feel her muscles strain as her body began to stretch. “P-p-please stop.” The mare sobbed.

The feeling of violation, and debasement was palpable, and yet despite the fear and pain, there was also a deep, hidden shame. The creature’s size, and vicious nature meant it hit every pleasurable spot inside the mare’s pussy, making a heat begin to rise within her.

Liquid surged into her only to flow out a second later, giving the impression that she was being fucked by some strange entirely liquid creature. “Oooh.” The mare moaned suddenly, her eyes going wide as she realized what had slipped from her mouth.

The strange bubbling sound returned, giving the mare the impression that she was being laughed at, drawing a blush to her face.

When the liquid pressed back inside her it did so slowly, as if teasingly, making the pony writhe as she felt it trickle back inside her. As it did, the goo pressed down on her clit, making sure to tease the mare as more and more of it pressed inside her, rubbing the female’s love button all the while. “Mmmmf.” The mare groaned, trying to stifle the pleasure she felt building inside her and failing utterly.

She could feel it even now, the pleasure that should not be was rising inside her, making her wonder if her first thought was wrong. What if this creature wasn't evil, but rather, simply horny? The mare shivered as she felt the creature bulk back up inside her, filling her tight passage with its slimy length. As she felt that pleasurable feeling of fullness and stretching begin to return she wondered something she would have never imagined herself thinking.

What if she just let it have its way?

It was clear she couldn't resist it. The creature was too strong, had captured her too completely, and there simply wasn't anything she could do about that. In such a situation wasn't it logical to simply give in, just for a little while.

The mare’s hooves fell slack, her wings returning to her back as she felt resistance slowly begin to bleed out of her body. She knew this wasn't right, and it wasn't what Rainbow Dash would do, but it was definitely something Fluttershy would do.

“Just be g-gentle, please.” She whispered, hanging her head in defeat, and hiding the blush that threatened to spread across her cheeks.

The goo writhed suddenly, undulating strangely before returning to its normal appearance. Fluttershy raised an eyebrow at the sudden burst of activity and though she wanted to ask more questions and maybe get through to this strange creature, movement inside her drew her attention.

The already considerable amount of goo that had already flowed inside her suddenly ballooned outwards, making her pussy stretch to truly massive proportions. The mare’s jaw hung open as she felt her body be forced to take far more than it was meant to, yet where she expected pain, she felt none. It was as if she had suddenly become more stretchy then her biology should normally allow.

Fluttershy hardly even had time to process this new information before she felt a new wave of goo surge into her pussy and travel deep inside her. She would have assumed it would stop at the entrance of her womb, yet it did not, slamming into the divide with such force that much of it managed to pierce the barrier.

Again there was no pain despite the fact that Fluttershy knew such a thing should be incredibly agonizing. A shift in the goo brought her attention back to her cunt where the liquid pulled out of her, leaving behind what little had managed to pierce her womb behind. Just as she was about to ask what was going on she felt it surge back inside her, adding another wad of black liquid to the now growing pool of it that gathered inside the deepest reaches of her marehood.

The mare shuddered, her wings extending as her hooves twitched randomly. Every drop that landed inside her was another burst of pleasure that threatened to overwhelm her.

The feeling was an utterly alien one to the mare, as it felt good, almost fulfilling but not in the way she would have assumed. Another surge, another healthy dollop landed inside her womb, causing her body to shudder. Again the feelings assaulted her and again she was left wondering what it meant.

It felt almost as though she was being stretched, but it wasn't the same as when the liquid filled her pussy and gave her that kind of stretching. Another surge, another wave and already she could feel her womb begin to fill completely, and the mare knew she wouldn't be able to take much more of this.

Yet she did not cry out, fight back or resist in any fashion, and though she reasoned that resistance was simply futile, there was also a darker reason, one that made her want to do nothing more than give herself to the horrible creature. In some strange, alien way she trusted it and knew it wouldn't hurt her, it needed her to fulfill it's lust after all.

“Go on, fill me.” She whispered, spreading her legs and waiting for the last wave that would fill her womb completely.

The liquid reacted instantly, writhing with palpable pleasure before pulling back and slamming inside her with enough force to rock her forward. Her womb filled utterly with the undulating black goo, making her body stretch in a way that she had never known could, her stomach distending.

The mare shuddered in pleasure, feeling pleasure the likes of which she didn't know was even possible. It was strange to think, but despite being so incredibly full, she could only think of how she wanted more. Her belly bulged, her womb stretched as even more of the black liquid was forced inside but still she wanted more, she had other holes to be filled, other parts of herself to be given to the black beast.

As if reacting to her desire a thick mass of goo pressed against her asshole, slipping past the small resistance her hole put up before sliding inside. “Yes!” She cried, arching her back and spreading herself as wide as possible.

The flow increased, turning from a surge into a torrent, her asshole forced wider and wider as more and more liquid flowed into her. Yet it still wasn't enough, she needed more, she needed to be used, to be filled and to be remade anew.

With wide excited eyes she plunged her face beneath the goo, feeling as the creature now caressed the exterior of her entire body all at once. It was like a million million feathers all touching every inch of her at once, yet even still it wasn't enough pleasure, still wasn't enough of the goo inside her.

She craved more.

The flow inside her womb increased, and she could feel as her cervix be pried open, allowing more and more to stretch and distort her body into a new and altogether strange shape.

More. She thought.

Her already full womb distorted ever wider, a fresh wave of liquid bloating her body so extremely that her belly bulged as if she were already six months pregnant with triplets. Her stretched asshole was forced even wider still, her every pore and inch of her body slowly stretching and filling as more and more of the goo entered her body through every available hole.

More! She cried wordlessly.

A burst of liquid plunged down her throat, filling her mouth in an instant and her stomach only a moment later. The taste was beyond compare, it was power, it was corruption, it was unspeakable, and it was the best thing that had ever graced her tongue in the entire time she was alive.

She didn't care that she should be breathing right now, or even that she could feel every inch of her intestines fill with goo, the pleasure overriding everything. She wanted for nothing, craving only to serve the goo as best she could, an urge that the black creature was all too willing to fulfill.

Litres upon litres of liquid poured inside her, filling her every pore and hole, yet still more came. Black tendrils of corruption coursed through the mare’s body, filling her beyond what should be physically possible. Her stomach bulged, and her flesh writhed, as black liquid coursed just beneath her skin, filling every inch of her body and remaking her anew.

She could feel the pleasure of the goo creature and knew it's joy. It had nearly completed the reason for its existence, and with that realization came a dual burst of pleasure that made both beings twist and twitch with shared euphoria.

Fluttershy knew there was only one last thing that needed to be done, only one last action that needed to be completed before she could join with the creature and become one. She needed to give in completely, to commit herself to become like it.

She didn't need to think long, her eyes instantly snapping open as she wordlessly cried her answer into the void of the goo.

YES, A THOUSAND TIMES YES!

The push of liquid surging inside her doubled, then doubled again, hundreds of litres filling her comparatively tiny body as she came harder than she ever had in her entire life.

Fur grew black, and disappeared entirely, flowing into the mare’s skin which softened until it was as black and formless as the goo that had formerly filled the room. Wings vanished, eyes became completely black, as her mane and tail vanished completely, replaced by a black mass that extended from the mare’s new body.

The last few drops of goo gathered around the mare’s hooves before being absorbed into her, the room now completely devoid of the black liquid that had nearly filled it only minutes ago

In its place stood a tall, confident creature that knew itself as Fluttershy, a wide smile on her face.
