Not Alone in the Dark

It squirmed, writhed, and billowed in the corner of Sonata's room, a black and oily cloud of that seemed immaterially there, as though it was simply made by the absence of light in some places, and in other, something sinister and so black it looked like a hole, but it was never in same places, drifting and drooling from the depths of her closet, at the foot of her bed.

She could hear its noises, softly, but surely they weren't real, surely none of it was real, a sound like teeth scraping against each other or little stones crunching beneath feet. The air smelt faintly burnt, not like a fire, but like the nose-sour smell of ozone after electrical burning.

Sonata was having trouble sleeping in her room these past few nights. Something was causing issues and preventing her from actually sleeping. Those noises, that smell. It was distracting and oddly enough, for a siren girl from another world. It was starting to bother her. The blue skinned beauty lay in bed and cuddled up against her blankets that much more, hoping they'd add some additional comfort to her growing unease.

Of course, she had brought this up with Adagio and Aria a few nights ago and naturally both of them, told her to grow up and stop drinking so many sugary drinks before sleeping. Which she did. But those noises still continued. The girl was worried, but she'd close her eyes and turn her face into the pillow, hoping to just drown out the noises.

It was one thing to be hyperactive, to have an overactive imagination. To see shadows out of the corner of your eye, or to think something was outside moving when there were branches in the window. But no matter how much the other two insisted, or how much she told herself, this didn't seem like any of that.

The room seed darker when it appeared, as if its very presence sucked what little light was there out of it, the glow of her fish tank for instance now seeming like a dull and distant light, like a dying streetlight in the distance on an empty road. Most of the time, it would just stay there in her closet, and chitter, dark miasma emanating off of it as it billowed and turned.

But it doesn't seem so restful tonight, and the chittering is growing louder, inky black tendrils whipping out in slow rising and falling motions out of its body that seem to caress the walls and the hanging clothing. Suddenly, with a rustle, it starts to inch closer.

The poor siren heard those noises growing louder and louder. Something was wrong and the siren knew as such, stirring in her bed the girl just wanted to sleep. But this noise was distracting and she'd slowly turn her head away from the pillow and look toward the corner of the room. Sonata could see the strange mist, the darkness that seemed to be moving and now she could see something else.

Squinting her eyes she tried to spot the waving like motions in the darkness of her room, before turning her eyes to take note of her fish tank that was giving off a low-dimly lit light.

"W-What?" The girl mumbled to herself, though it would be moments now before she'd scream.

What had been a single creeping 'step' springs into action as the shambling mass moves furiously across her floor and closes the gap between them almost instantly, writhing and squirming and drooling darkness as it rolls up onto the covers and on top of her, seizing her with black immaterial limbs. Tendrils lash out and like razors saw her blankets to ribbons, treating the one thing 'protecting' her like the nothing it is before doing much the same to her clothing.

As her minimalist sleepwear gets tattered and sliced, small little cuts forming on her hips where inky darkness lashes out at the fabric, deep shadowy limbs like slimy black trunks unfurl out and wrap around her ankles, around her wrists, pulling her suddenly and violently inward, where it envelops her in oily pitch blackness.

Slimy nothingness that wrapped around her body while invisible tendrils as thick as her fingers coil and curl around her tummy, around her thighs, kneading spirals into her ass, groping and coiling around her tits.

It's almost impossible to tell whether its molestation is purposeful, or whether its all just part of it latching onto her. She can't see it happening either way; her vision falls off just inches before her eyes, leaving her in a pitch black billowing cloud of gnashing, chittering nothing.

Things weren't looking too good. Having felt those tendrils lash at her clothes, cutting her nightdress into shreds as well as her blanket. The siren was snatched by the wrists and ankles and hauled into the enveloping darkness.

"Stop!"

The girl cried out loudly, as she'd struggle and pull against the restraints. No-matter what Sonata did, she just couldn't break free from the bonds that held her captive.

"W-What the fuck is happening?!"

The poor siren cried out in both fear and and protest. Sonata couldn't see a thing, nothing but blackness before her and yet all she could hear was those awful noises. Those same chittering noises that surrounded her head, making those ghastly sounds as she'd shiver throughout her entire form. When those finger like grasps could be felt around her tummy, her breasts and backside and that invading like spike to her asshole; she'd grunt out in distress.

"Hngh! Fuck! No, stop fucking... nnnagh!" She'd then thrust her head back in sheer protest, then twitch and shake.

No matter what noise she made, it seemed like it became lost in nowhere, echoing against void and coming back sounding distant and muffled, like shouting through a pillow or murmurs underwater, reverberating tingly off itself and bouncing back.

'Stop! What the fuck!' And so on and so forth. Could anyone even hear her outside of it? Surely if she was loud enough, Adagio or Aria would come busting in telling her to keep it down and go back to sleep, right? Right? As she writhes and spasms, the things that hold her seem to have an almost elastic give, sharp jerks letting her move a few inches before it snapped back into place, roughly tugging the limb to full extension as these dark tendrils continued to swarm across her.

It felt like they left oily, slick trails across the skin as they writhed and surrounded her, prodding and poking wherever skin folds or dips inward, sliding and squirming across the underside of her tits, under her arms, in between her groin and her thighs, up and down the blue cleft of her ass. But strangely it felt like her pussy, thought exposed to the tingling numbing sensation of this shadowy darkness, was left alone... for now. Suddenly, her thighs are jerked outwards, hard, the slimy trunks around her ankles forcing them open and apart,

Sonata could hear the echoes of her own voice, it was muffled and sounded quite distant. That was a problem. If she couldn't scream for help, then none would come. Hopefully one of her siblings would come in to check up on her and spot what was happening and give assistance. But that was unlikely, as perhaps her sisters were busy with other matters.

The blue-haired beauty continued her struggling within the cloud of void darkness. Her body being forced back into place when she did struggle, her resistance seemingly more futile with every passing minute. Suddenly the poor girl would feel her legs, her thighs being spread open and pulled wide - painfully. The late teen groaned out in a harsh tone as she didn't expect it and in doing so, she'd tipped her head backward before bringing it up normal again.

"Aaaaaaaargh! FUCK! T-That hurt... ugh... let me gooooooo! Don't touch me down there!" Sonata pleaded. As if she were hoping that whatever this thing was, she'd be able to reason with it.

If it understood her, if it even heard her- there's no way she can tell, as it's strange chattering, grinding voice echoes in her ears, an- Ah! Teeth! Or something like teeth, smooth and hard and sharp, pinch at her neck and shoulder, feeling like jagged glass as it gnaws and scratches but not yet breaking the skin.

Almost as if her protest summoned it, she feels something swirl into being against her cunt, first a little point of sensation that turns and expands quickly with the sound of crunching stone until its a pulsing, churning, fuming pillar, prodded against her dangerously. Not that she can see it, but she can feel it.

As broadly tipped as if it was a fist, it mashes and squeezes against the soft blue lips of her pussy leaving them feeling numb every time it does, turning slowly in place like a cyclone as it does, dragging with an immaterial friction against her labia as it tests and teases. Meanwhile higher up, the tendrils coiled around her tits wrap around them viciously and squeeze, hard, tugging them while tendril tips tweak and flick at the nips.

As the shadow molestation continued, Sonata was still at the mercy of this unknown entity. The shadow still holding her captive and doing what it very well pleased. When Sonata felt those jagged points against her neck and shoulder, she'd tense up and hiss deeply as if she were expecting to be bitten or cut. But alas it did not happen.

Her body still held at it's mercy and she'd twitch and squirm, like a worm on a hook. However something pushed against her sex and while it didn't penetrate her, she could tell with her close it was; that it sought to do such an action. Sonata tensed up against and chewed tightly upon her lower lip, terrified of what it was going to do. But instead it just rubbed against her nethers, but that was all.

"Aaaaah, aaaaah... what is happening...!"

Sonata protested and when her large breasts were coiled and squeezed, she'd groan out deeply and shake her body in response. It hurt, but oddly it was a nice sensation for the masochist girl.

"Mnnnargh... fuuuuuuuuuuck!"

It's writhing grasp pulled and squeezed her breasts almost crushingly, certainly hard enough to bruise, enough to briefly elongate her rack as those same teeth she felt on her neck grazed and nipped at her nipples, sharp points pinning into either side brushing back and forth while the darkness tugged and yanked on her rack.

Suddenly the pillar between her legs lost patience, and thumped upward, punching into her girlhood hard enough to make her whole body bounce, for her to feel the shock of the impact in her pelvis, but still not hard enough to force its way in; So it does it again, and again, every time the chattering noises rising up into a roar, until with cruel and heavy force, hammers in and splits her tender pussy open around a blunt tip four or five inches across.

It's rim digging into the walls of her cunt as it sinks in three inches before coming to rest, churning and writhing and vibrating furiously, spinning against her interior walls while something thick and sludgy spurts into her, splashing against the back walls. No one is coming, it seems; surely Adagio and Aria would have heard it by now.

The poor siren squirmed and shook around as best she could. This was due to the pain she was receiving from her breasts being squeezed so tightly. Even since the siren girl was indeed a masochist, she was having her limits tested by this thing, this toxic creature.

"Uuuuargh, my tits... fucking... jerk!"

Sonata cried out in protest, feeling her sex indeed starting to dampen from the position and the actions taken against her lewd, sexually crafted body. It was true however. Sonata's body was purely created for lust and deep pleasure. But when she felt that punch like sensation against her sex, she'd pause for a moment with widened-eyes.

"Ugh!"

Then it happened again and again and it was then that Sonata started to groan out painfully, screaming as she felt that forceful thumping against her darling pussy. That was until she was suddenly penetrated and that blunt tip, sinking a few inches inside and she'd drop her head back, shivering throughout her entire form.

"Mmnnarrrrruuugggghfuuuuuuck..." A deep shake spiralling through her body, as she'd endure that new invading inside her body. Which was leaking some sort of liquid inside, making her whimper and grit her teeth. "Aarrrrrggh..."

Finally inside, the monstrosity drove itself violently into her, the abominable shadow having its way with her frame as it forced its way deeper inside, her flesh straining to accommodate as it pushed her interior aside and stretched her so wide it felt like she was going to split in half. It moved forward unrelentingly deeper, until finally meeting her cervix, her stomach bulging at a strangle angle from the intrusion.

Something opened in the darkness in front of her, something barely seen against the shifting void, inches from her face- ovoid and slightly angled at the edges, something glowing with a strange kind of blackened light glossily shined in front of her face. And then several others appeared, swarming her, watching her, eyes in the darkness as hundreds of tendrils manhandled and had their way with her curvaceous fuckable frame, and as mouthless teeth prodded and grazed and bit at the surface of her skin, none of hem yet piercing... as far as she could tell, anyways. It wasn't like she could see what they were doing.

Sonata squirmed and groaned heavily, feeling that invader push further and further inside her darling sex. It was pushing her to her limits, that was for sure. But when she felt that presence change, she'd push her head back upright and stare into the darkness and it was then, that she could have sworn she saw something staring back at her.

As the poor siren continued her moment of mixed sensations of both pleasurable and pain, she'd feel many more tendrils devour her bodies surface and continue their exploration of her perfect frame. It made her groan and release various little moans as she responded to it's each and every touch in her own little way.

While she still couldn't see in the darkness, she could feel everything that was happening and honestly the poor girl didn't know what was happening. Was she cut? Was she just feeling oily liquid along her skin? While a slight roll of her eyes, Sonata continued to endure - but for how much longer, only time would tell.

Angrily, frustratingly, the pulsating whirling black smoky pillar grinded against her cervix, painfully squeezing up against it, its motions intensifying as it failed to make its way through. Almost like it was furious at her, she could feel the teeth on her shoulders grind harder, scratching against the skin while the sound of pebbles crushing became a howl.

It almost seemed like it would all be over right then, before it suddenly seemed to calm... only for the violation to pull back and begin rhythmically thrusting, driving back and forth inside her, freshly stretching and brutalizing her walls every time, overwhelming sensation flooding her nerves and rippling up her spine, painful discomfort and body spasming pleasure doubling and intensifying against each other and squashing any other thought. Minutes and seconds bled together as it thrust mercilessly, her tummy rising and falling as it plunged into her and continued to spin.

The sensation of pleasure and pain mixed together, sending the siren's mind into a blur of emotions. The girl didn't know how to react to the situation she was within. While her head was tipped back, that biting upon her shoulder seemingly getting more aggressive before calming, it was confusion on many different fronts.

Yet the girl was terrified of what was happening, but yet, no one came to her aid. So she continued to suffer at the tendrils of that unknown creature. It continued to beat into her sex, working her walls and inner defences to their very peak. The girl was a drooling mess at this point, both quim dribbling from her sex and around that shadowy tendril and some leaking from the corner of her lips.

"Uuuargh! Mnnnrraggh, no... I'm gonna... cuuuuuuuuuuum!"

Sonata in a surprised and aroused state, released herself and came against the creatures invading tendril; while her body spasmed and shook throughout. Not one inch of her body could she control during this moment as the siren climaxed and experienced quite literally a cunt-shattering orgasm.

"Hnnnnnnnnnnrgh!"

It became impossible for her to tell how much time was passing as it kept on at her, ravaging her rapaciously, her only meaningful sensory inputs the feeling of it all surrounding her and forcing its way into her, the way it was now clearly gnawing at her shoulder- though the pain was muted to something more like a dull throbbing annoyance, she could feel the way it dug, the way the glassy razor teeth wedged into harder tissue, there was no way it wasn't piercing and chewing through the skin, even if she couldn't feel it, even if it didn't quite feel like it.

She didn't know when it happened, but she could feel the violating tendril go deeper and deeper- it had forced its way into her womb, and she could feel her torso distend when it forced all the way inside, sharp flexing pain somewhere at the centre stabbing into her as it grinded back and forth at the formerly miniscule entrance, slamming in and out in rapid short bursts hard enough to make her cough or hiccup.

It had poured its lecherous ichorous essence into her continuously, and she could feel herself bloat as it pooled and sloshed like slow, heavy tar, belly gravid and taut with all of it inside her. The grinding, chattering, chittering... perhaps she was just going crazy, but it sounded like it was laughing at her.

Sonata was losing her mind. She had just experienced such a painful yet satisfying orgasm, and now she was drooling from both holes. When she felt that invasion of her sex, punching inside of her womb now - her body felt weird and in fact she'd orgasm a second time from the sheer sensation of this obscure pussy-fucking she was going through right now.

Eyes rolling into her head, her body twitching and shaking deeply as her body continued to endure such a unique fucking. It would be a long time before she could feel her pussy again at this rate. Those noises, they filled her mind again and made her quiver, it was all too much for her.

"Uuuuuarghmmmmnnnuuugh... stooooooop... mmmmmooooree.... fuuuuuuuuck... ing... meeeee...!"

However the creature wasn't quite finished with the poor siren. It's tendrils continued to violate the girls body and enjoying her holes to it's own bewildered amusement. Enjoying how her body rocked and twisted, how it shook and squirmed. Penetrating her most precious and delicate of areas and showing it's dominance over the young lady, but it was almost finished.

Once the unknown entity felt that second orgasm, it knew it had enough and was satisfied for now. All those tendrils retreated from their forced entry points and joined it's main body once again. Sonata was left hanging in the void, surrounded still by it's black unknowing form. During which the mysterious creature was taking it's moment to soak in the victory of it's recently enveloped prey.

Sonata could feel her fingers being tugged at, every part of her body was being touched and sampled a final time - as that plush, erotic body was being enjoyed before the creature squeezed in around the blue siren and focused on Sonata's head. Numbing her mind and forcing the girl into an unconscious state, before the shadow itself evaporated into nothing and vanished from the room entirely.

The out-cold body of Sonata landed flat, face-down on the bed with a mighty thump. Leaving her in a soaking pool of her own liquids, so that she could marinate within them until she'd next awaken. Upon her reawakening, Sonata would need to seek council with her siblings. For it could return, and for whom it would next seek, would yet remain, unknown.
