Kathy

The warm water drizzled softly down upon Kathy and she moaned and basked in the relaxing rain of the shower.

Relaxing in the steamy air Kathy’s mind drifted to one of her guiltless unconfessed sins.

The shower’s steam wafted about her, enticingly full with the scent of a wet pussy. Kathy licked her lips, her mind drifting to the last time she had engaged in the taboo act of laying with another woman. Part of her mind questioned how it could be drifting so, how she could be so wet and fragrant, could Emi smell her from over by the sink, or was it Emi she was smelling?

Kathy clenched her eyes shut and breathed a deep, shuddering breath as her fingers danced across her skin, bluring the line between washing and teasing her skin.

Kathy’s mind simmered in the taboo idea. It was so wrong, but clung so powerfully as it seemed to effortlessly, and powerfully climb from the perverse depths of her mind to dominate any other thought or idea.

Kathy new it was wrong, but it was just a fantasy. A fantasy she couldn't help but fantasize about at the most likely chance of getting caught.

Exhaling a long soft moan, confident it’s sounds was suppressed by the warm spray ppeling her in a poor effort to pressure wash the deeply ingrained dirty thoughts from Kathy’s physical being.

Slowly opening her eyes her gaze peered out from the shower, the question of just when the shower curtains in the shower tub combo had become a glass wall in a walk in shower absent as Kathy found her heart skip a beat, her eyes fluttering open and closed as her half lidded gaze locked on Emi with unremorseful guilt.

There was her younger sister, leaning against the bathroom counter, legs spread, one hand clenching a breast, it’s fingers rolling a nipple, as the other brazenly toyed with her clit as she panted passionately staring at Kathy’s naked body in the shower.

God why am I such a slut… Kathy wondered, finding her will to resist the slow pull of this taboo temptation waning.

Kathy lost herself in the arousal and excitement of just what was transpiring. As they masturbated to each other masturbating to each other. A strange cycle just seemed to keep building without any relenting.

Just cum… Kathy begged her body, her mind, herself. Kathy pressed forward, wanting the simple perversely excuse to just stop. Desiring to see Emi cum first as Emi rolled her head back and loudly declared her incoherent pleasure.

Just cum, Kathy felt herself muttering as she leaned back against the shower wall eyeing Emi’s seemingly ever more curvaceous body up and down. Taking in the curling toes on the ceramic floor, the slow deliberate drag of two finger across Emi’s clit in and out of her pussy between trembling spread thighs, ass resting on the counter.

Emi eyes seemed to almost glow a golden yellow as she screamed out in orgasmic bliss, body trembling as she shuddered and visible squirted pussy juices out onto the floor before her.

Kathy cursed herself for finding it so hot, squirming on the cusp of orgasm wanting nothing more that to fall over into the void of peak pleasure, trying to expel the dirty foreign, yet enticingly welcome thoughts of seeing Emi crawl across the floor, licking her spilled juices from it.

It was clear Emi wasn’t done, as she sucked each finger from her pussy clean, before slowly, long, sultry licks traveled up her wrist and across her palm, cleaning any trace of her pussy from the skin of her hand.

Watching as Emi stood, staring hungrily at her. Kathy cursed herself for wanting to see how far it could go, swore at herself for not being more willful against her perverting thoughts.

Her mind racing in concern of just what Emi would do next, each step towards the shower heavy with sexual allure, grace, and confidence that only a predator confidently before cornered prey would have.

But the walk wasn’t the only excitingly wrong tthing Kathy was taking in.

With each strut forward Emi’s body seemed to change even more. Shifting skin colour, black horns slowly developing and lengthening. Kathy couldn’t believe her excitement at this, the perversion of sin damning her younger sister, twisting her into a demon.

A sex demon, her sister, an all consuming sexual desire coming for her sinful condemnation.

How could this dream feel so real?

The glass echoed with the suddenly thud of Emi slamming herself against it. Her tiny nipples compressing flat against the glass as she ground against it, one clawed hand spread flat, the other fingering her pussy. Long, forked tongue graphically licking across the glass.

“I know you want this.” Emi confidently moaned. “You were always the most sexu.. unlike… of us.” Emi’s voice panted tauntingly at the rallying resistant and fearful thoughts within Kathy’s otherwise moral, and devout being.

"Noo…" Kathy gasped, and moaned. Questioning just why she couldn’t stop touching herself.

“But we already have.” Emi replied, “You took the least swaying.”

Kathy shuddered and gasped, feeling herself spasm and twitch in paralysis as a memory ripped through her brain.

She had masturbated to climax.

She had kept going, fantasizing about Emi catching her.

The excited idea growing even better when Emi ripped the shower curtains opened.

How they fingered each other, and the sweet taint that rolled across her tongue as she suckled on Emi’s breasts. How she had been fed and nurtured by her younger sister as if a child.

And still wanted, and yearned for more.

“GOD!!!” Kathy shuddered and spasmed, jolting upright somewhere else as the sensation of Emi eating her out for the first time faded.

The pause was brief, Kathy’s hand quickly playing with herself as she considered just what she just recalled combined with the strangely too real encounter in the shower.

As Kathy clenched at her body she irresistibly moaned at its increasing sensitivity, it’s unrelenting beckon to be pawed at as she palmed her breasts, and fingered herself.

Her Eyes only opening to truly look around as she heard another set of calls echo in response to her own.

”I don't know what came over me. I just had to..” Carolines words were drowned out by Kathy’s own voice whimpering as she threw her head back, suddenly recalling how she had found Caroline the day after her encounter with Emi.

God it felt great to masturbate to another Sister getting off, Kathy questioned if Caroline would come over like Emi had.

Or if she herself should crawl atop Caroline, thoughts of grabbing Caroline’s frizzy blonde locks and muffling any objection with her pussy on Caroline’s lips.

Kathy watched as Caroline pulled out the all to familiar vibrator and went hard to town. Kathy remembered Caroline pleading to be watched, and did so without hesitation, her mouth grinning madly as new ideas of how this could play out manifested, and vibrator increasingly looking like a dark chitinous and ridged double ended dildo.

It twitched, and squirmed as if alive, increasingly moving as if a life form of its own as Caroline lost control of her body in the maddening throws of pleasure.

“D...d… do.. you… ike…. Wa..ttt… you…. See…” Caroline gasped staring into Kathy's eyes, Kathy responding without the slightest hesitation.

“Yyy…. ess….” Kathy moaned in response rolling over onto all fours, she was done waiting for this to play out. She was no longer concerned about what it could mean, or implications.

As she crawled atop Caroline, pinning her by the throat on her back with one hand, and guided the phallic toy into her nethers. Bridging their separate pleasure together, amplifying the lust inducing demonic artifacts influence with her own motions to fuck atop it, pressing it deeper into Caroline with each press down.

Kathy grabbed Caroline by the throat and stared deeply into her sisters eyes, finding her arousal growing maddening as she fucked her sister. That’s exactly what Kathy admitted she was doing, not just fucking herself with the same toy, but fucking Caroline with it. Kathy watched her sisters eyes change colour, her skin glistened and shifted to a pearl hue, and her features grew more attractive and demonic.

“Yes…. Yes… Do it… More…. More….” Kathy moaned barely coherently as she fucked herself, and Caroline with the toy between them. Losing herself to the twisted thoughts and joys that the sin was physically corrupting and changing her sister. That their wrongfully act was tainting them irreversibly, changing them into what they deserved to be.

As she felt the release of orgasm cusp, Kathy cried out in desperation. Pleading to the dark void that enveloped her, before relaxing and basking in the strangely exciting restrictions she now felt on her stretched out body.

“You need to release yourself.” The voice was all too familiar, yet elusive for Kathy to identify. It whispered in a tone of hushed secretive promises. A husky tone of misbehavior and pleasure all too familiar for a teenager fooling around.

Squirming against the restraints, all Kathy sought in the void was to touch herself again. Some small act to resume the strange spiritual journey she was on.

A moment of eureka dawned on her mind, that’s what this was. The details were foggy, but this was some spiritual test… Shock and disappoint added to the aroused squirming as Kathy grew concerned she’d had already failed it.

Even as she remembered some of the true memories that lead her here.

The hot tub, God how she would’ve done that different had she known how it would go. Her mind delighting at the idea of just dunking beneath the hot tubs surface and demanding the others just get started when Claire surfaced.

Breakfast, the memory of each of them fucking their father, the tentacle beast in Emi’s apartment. Kathy lost herself on just how amazing and strangely perfect the memories were, able to acknowledge it was really her, yet strangely finding revelations in who she was, and just what her sexuality really wanted.

With each embrace she felt her restraints release, the final acknowledgement dropping her onto all fours, down to the slimy wet floor in the dark void.

It's viscosity and smell gave Kathy a perverse chill as all she could think of it being was the spilled sexual fluids of hundreds, if not thousands.

“Is this truly what you want?” Slowly gazing up Kathy beheld Emi’s clawed demonic feet, perfectly toned and shapely legs, smooth hairless slit, glistening and emitting the most arousing musk, billowing breasts, and twisted delightful smile.

She had seen Emi like this briefly, it was only a glimpse, a motion filled blur that seemed to emerge from that mystical portal they had opened as quickly as she had gone in.

But she wasn’t alone. The other demonic form, black feathered wings, perfectly shaped ass, whispering in Emi ears before starting to walk away.

Kathy some how just knew it was her demonic manifestation. It excited and aroused her more, she began fingering herself and moaning aggressively to try and draw a glance. Kathy just needed to know just what she would look like, wanted to see just how all her tainted sinful action would weigh on her.

Like Marley’s chains in A Christmas Carol.

As concern mounted of losing sight of the potential fate in the void a brilliant fire surged up and enveloped Kathy’s last glimpse of that ass. It’s tail. The spread arms and wings.

“Are you ready to burn in eternal hellfires for your sins? Do you want to confess, be absolved, and commit to never do them again?” Emi asked crouching down, her eyes alive with joy as they gazed into those of her prone sister touching herself.

Kathy felt sudden weight on herself, a suddenly acknowledged soulful burden. Her stomach was in knots, she wanted to feel like she was sick, yet still couldn’t help but masturbate.

Panting, and gazing at the fire stoked from her sin. Trying to dispute the pangs of excitement as they seemed to flicker, and surge with her pleasure.

Emi was suddenly gone, but there was a silhouette in the fire.

Be reforged

Be reborn

Be the child of a different god.

Kathy felt like she should do something.

Get up, run. To or from the fires? Her eyes glazed over as she kept fingering herself, crushing her tits down against the void, a perverse awareness emerging that this God. This dark, perverting, evil, “false” God was the void, and it already had enveloped her.

It was the leviathan of her sin consuming her.

She could feel it groping her body with the darkness, pinching, pulling, and somehow sucking teasingly across her whole body all at once. As Kathy’s mind wandered down this path and embraced it the sensations grew stronger, and advanced.

It was fingering her pussy along side her.

It was fingering her ass…

The flames grew stronger and advanced, their flickering flames casting shadow and giving glimpses of potential billowy forms of darkness that were this incomprehensible thing violating her.

Except it wasn’t. Kathy was allowing it.

Kathy screamed in pain, agony, and the pleasure of a thousand deprived orgasms as the fires suddenly surged and enveloped her. Their colour shifting from the all too familiar hues of normal flame. Growing vibrantly bright and purple.

Kathy felt as the fires destroyed her body, scorching and destroying what had been Kathy.

The snaps, and crackles of flame branded her. Marking her as human no more, sharing the secret name that now eternally held power over her.

As the flames died down the void dispersed, leaving Kathy on that ball room floor. Her tail fucking her as she rocked on all fours, hungrily gazing about to see just how twisted her sisters had become. Large G cup breasts pillowed beneath her, kneading and rolling as she embraced her now true worldly form. Her eyes glowed with the bright purple flames that engulfed her and now flickered above her ram horned head in a halo. Her straight hair fanned out across her back and hung down over her shoulders, a shiny red wine in colour.

Her chitinous claw crushed into the stone floor with ease, their black sinuous Chitin ascented by the lavender of her otherwise expose skin. Darker spots and stripes of purple.

And she basked, in a twisted gratitude as she felt her dark seed eject into her causing her to twitch and tremble in new climactic ways.
