Later:

Ana slapped Leah hard across the face, and her Sister moaned with pleasure.

"Yes!" Leah hissed. "Harder!"

Ana slapped her again, getting an even louder moan out of her. It made Ana's quivering lips contract with lust. She had been waiting so long for this, and now it was happening at last. She felt as if she'd been edging herself all day long, controlling Leah, betraying her, seeing her claimed and seeing her become the Mother's cruel and soulless instrument. It had been so fucking good. It felt like she should have climaxed a million times over it already—but there had always been even more monumental dealings at hand. The death of Josiah. The birth of their Mother. The taste of her own dying soul!

But now it was finally becoming reality. The fight was done, and the Mother had won and Ana could finally enjoy the spoils of war. Leah was hers! Leah was willing flesh!

She slapped Leah again. "Do you like that, you filthy whore?"

Leah looked up at her from her knees, a mad grin on her face. "Yes, sister! Show me how fucking cruel you are! Use me, Ana! Rape me! Own me like you did when you crushed my mind!"

Ana hissed with delight, and shoved Leah off-balance, onto her back and into the pool of blood they had created minutes earlier. Leah immediately spread her legs for Ana—and Ana briefly considered finger-fucking her and making her come instead of the other way around. She was so fucking hot. Ana wanted her so bad. But the joy of domination was even better, and she knelt down into Leah's face.

"Make me cum, whore!" she said. "Make me cum and complete the Sanctum!"

Leah didn't answer. She simply obeyed, and Ana moaned with joy as Leah's shameless tongue pushed into her hungering slit, and across her opening, and against her clit. Yes!!! she thought and tugged on the scalding marks of ownership that pierced her nipples as she lost herself in the red hot reality of what had become of the two of them. They were the Mother's flesh, soulless, cruel and sadistic! The goodness had been raped from their souls, and they had betrayed their Order and killed them all! They had become everything they had sworn to destroy! Their once virgin bodies were defiled seedbeds, utterly tainted and corrupted and twisted, fangs and claws slowly growing and pushing out of them with no more pretense at humanity and modesty. Ana's cunt had become a seeping, throbbing temple to the One that would claim the world! And now Leah was worshipping at that temple like the shameless, soulless servant that they had turned her into. She was sucking ravenously on Ana's clit, and Ana grabbed her by her hair and pushed her deeper between her legs, deeper into the sacred place where she had been raped and claimed.

Ana moaned. Yes!!! Serve the Mother!!! Be her whore!!! Finally, the soulless monster that Ana had helped create could prove how little their pathetic friendship and so-called sisterhood had meant. Fucking her was the final nail in the coffin of their worthless former existences, and fucking her to complete the blood ritual of creating a Sanctum of the Mother was an even greater thrill.

Yesss!!! This was their glorious purpose! Defile the world! Make everyone serve! Ana looked to her side and enjoyed the sight of their prey: Next to them, stripped naked, eyes empty, breathing shallow breaths, knelt the innocent young woman she had forced to slit her own wrists. They had invaded her home, at random, and used her flesh like all flesh was meant to be used. They had dragged her out of her bed, subjugated her will, and used her blood to draw the symbols of the Mother's power across the floor and walls. It had been delicious.

And now Ana's orgasm would drive another beacon of Her Resonance into the world. Another Sanctum. Another place of power. They had kept the woman alive for what was going to happen after that. The thought was already driving Ana closer to the edge.

"Fuck yes! Harder! Harder!!!" she commanded, and squeezed her breasts as jolts of pleasure went through her body. She felt her abdomen contract, and felt the growing demon inside of her squirm with the same dark joy that was burning in her heart. They were one and the same. She was its demonic seedbed. Her body existed to breed and corrupt and to feel the shameless pleasure of domination and violence and sex—and all of it had become the same thing. "YES! HARDER YOU CUNT!" Leah's tongue was hot and wet between her quivering folds, and Ana's seeping gash was on fire with ecstasy. She was close. So close!

She panted, and held on. For a moment, she wanted to draw it out and enjoy it for longer, to make it more special. Yes. This would be the first time that Leah made her cum! Her sister! Her friend! She had killed her and made her serve! She had betrayed her! Yesss! It was so fucking hot to think about. It was so fucking good and it felt big and meaningful and she wanted it to last. She wanted—

—No! She wanted to cum now! This wasn't special! Leah was nothing but a shameless whore! She would be her bitch and her pet and her fucktoy, and they would spread the Mother's seed together, fucking each other's willing flesh over and over and over! Leah's body was hers to use. She was her whore! "Yesss!" she screamed. "YEEEESSSSS!!!"

She came, and her corrupted flesh bucked and shivered and rippled with the overwhelming heat of the Mother's Resonance—and the air crackled and reality shivered as her orgasm grounded Her power into the defiled and tainted Sanctum. It was done. Her boiling, hate-fueled climax had completed the ritual. Blood and sex, claiming the world in the name of chaos!

She laughed and moaned as she came down and felt the warm embrace of the Mother's will saturate the air around her like a red fog at the edge of her mind. "Well done, bitch" she said, looking down between her legs, into Leah's wonderfully soulless eyes. She saw them burn with selfish delight, and she knew that Leah enjoyed being her little bitch just as much as she enjoyed imposing her will on others. Speaking of which...

"Get up," Ana commanded, and the magically mind-controlled woman next to them blinked into dim awareness.

"Yes," she slurred, weakly. "I obey."

She stood, swaying dizzily from loss of blood, and waited for Ana's next command. Ana got to her feet as well, and Leah followed. The smile on her face had never left. She looked ravenous and desperate for the joy of inflicting violence, and Ana was more than happy to indulge her.

"Let us see how strong the Mother's resonance already is," Ana said, and commanded the young woman to kneel at the center of the Sanctum. The woman did not hesitate one second, and eagerly offered herself without understanding or questioning what was happening to her. It was so fucking hot. For a few moments, the both of them simply enjoyed the sight of a woman that was completely under her control and completely at her mercy. They waited for what they knew was coming as they felt the freshly empowered Resonance claw at their minds, throbbing with purpose — and the only question was who was going to be the first to fall under its control.

It was Leah. Her body trembled, and her eyes went glassy, and she boomed: "Her flesh is ready!"

Ana took in a sharp breath as she recognized the Mother's influence in Leah's voice, and she shivered as the thick heat of the Sanctum's resonance enveloped her, too. "Her flesh is open," she droned as the Mother's will took her over.

She started moving, and so did Leah. Together they let their tainted blood take control as they drew their arms through the air in slow circles. Unholy words escaped their mouths—guttural, harsh sounds, as inhuman and cruel as the burned remnants of their dead souls. The words of power cut the air like rusty knives, and reality broke and bled, and the woman between them suddenly screamed in agony as dark magic lifted her into the air.

And then it happened.

Her arms and legs splayed out, and her bones cracked, and her screeches of pain turned into an inhuman roar. Suffering and terror widened her eyes, and through the red fog in her mind, Ana could feel her magical control over her victim's will evaporate. But it was already too late for her. Her moment of freedom lasted less than a heartbeat. What mind she had left was already being twisted and melted by far darker powers than the superficial control that Ana had imposed. Their screaming sacrifice hung in the air, helplessly twitching and convulsing as the white of her eyes turned black and her irises tinted red just as the veins underneath her skin ran black with blood like a thousand snakes slithering through her flesh. Her body shook, cracking and gurgling, and blood started running from her mouth as fangs pushed themselves out of her gums. Horns erupted from her skull, and at her fingertips, her fingernails transformed into black, serrated claws. Her skin rippled, and creased, and darkened, and stretched, and she hissed and growled and snarled, and there was no more humanity in her voice, no more thought, no more fear. Her soul was already dead even though her body was still changing.

And change it did.

Ana and Leah continued chanting, continued their defilement, until at last, the transformation was complete.

When it was done, Ana felt the red fog recede and her own thoughts return, no less cruel and no less violent than the ones that had filled her mind when the Mother had been in control.

The whores of the mother looked at their work with sadistic pride. Leah hissed with delight. "Fuck yes", she said. "That's so fucking hot." Ana licked her lips. She had to agree.

Standing in front of them, naked and terrible and magnificent, was the first full demon of the mother's hordes. A monster born from human flesh, stronger and more dangerous than even the most corrupted flesh-servants, claws and fangs and horns ready to kill and maim. A being of pure evil, created by the mother's will. Ana looked at its magnificent form. It still superficially resembled the young woman it no longer was, but its skin was almost as chitinous as the Mother's Gifts, and its face was the cruel caricature of the woman it had once been, with huge black eyes and a mouth full of finger-long fangs, and sweeping horns arching back over its scalp. It stood bent and hunched, quietly snarling and hissing as it looked around itself and recognised its masters, and it tilted its head with a grotesque smile that seemed both thoughtless and way too smart at the same time.

"Yesss," hissed the newly-born she-demon. "Will serve now. Kill. Hunt. Command me."

Its eyes burned with violent malice. What remained of the woman's mind had become entirely corrupted and twisted. Everything she had been had been turned into pure hatred and obedience.

"Join the Mother," said Ana. "You know where to go."

"Yesss," the demon said, raising its too-long arms and looking at its own clawed hands with what looked like fascination. "Know how to serve. Know where to go. Will serve. Will go."

And with that, it half-walked, half-crawled away. It was as unnerving as it was exciting to watch it open the door, frighteningly human and inhuman at the same time. They weren't too far from the library—just far enough away from the center of her Resonance to warrant the creation of a Sanctum—and it would have no trouble finding its way to join the growing masses of the Mother's army.

"It worked flawlessly," Ana said, smiling a satisfied smile. "Her powers are as strong as they ever were. Jordan's flesh is a worthy host."

"Yesss," Leah said, and nodded, and surveyed the newly created Sanctum: A chaos of overturned furniture and wonderfully sacrilegous bloodstains. "Can you believe how fucking good it was to see that black whore die and become Her flesh?!"

Ana scoffed. "You were still my mind-controlled slave when that happened," she said. "If you could have, you would have screamed and cried."

Leah took a step closer to her. "But I still remember it now," she said, biting her lip playfully. "And when I remember it, it makes me want to cum, hard."

"Is that so?" Ana asked, a smile on her lips. "And is the memory even better because that bitch Leah was powerless to stop it? Is it even better because I was in control?"

"Don't flatter yourself," Leah said, smiling as well. "Just because I can get into being your little bitch doesn't mean that I'm any less of a greedy, reckless monster than you. I would've taken those rings from you and choked you blind if I could have. I would've pushed you down into the blood and fucked your face if I could have. I'll be your bitch, Ana. But don't think for a second that I won't take everything for myself that I can get. And that's not what you want, anyway—is it?

"...what?" Ana scoffed. Leah was directly in front of her now, and Ana could feel the heat radiating off her flushed body.

"You don't want me to be a little submissive bitch, Ana. Not as much as you get off from me being the Mother's monster. Not as much as you get off from knowing that my soul is dead and that I'm just as fucking cruel and evil as you are."

Ana's lips felt suddenly parched. Somehow, she had no reply.

Leah wasn't done. "That's right, isn't it?" she hissed mockingly. "You could just control my mind and turn me into your drooling little fuckpuppet and lead my on a leash like the little bitch that I am. But you don't."

Leah was maddeningly close to her, and the utter cruelty in her eyes was unbearably hot. Ana realized that she was holding her breath and that her body was shivering.

"You fucking don't," Leah spat, "Because I'm already exactly what you fucking want."

Leah let the moment hang in the air, a wicked grin on her lips.

"And what is that?" Ana finally asked.

"I'm your fucking girlfriend," Leah said mockingly—and Ana scoffed.

"Fuck you!" she sneered. "I do not give a shit about you, you little cunt."

"Oh, is that so, Ana? Really? You're telling me that you don't want to fuck me every day for the rest of eternity because I'm the one you betrayed most? You don't want to be there every time a newborn Gift claws itself out of my flesh? You don't want to hold down my victims with me and make their flesh serve? You don't want to do it all together because it would be such a fucking constant joy?"

Leah looked at her with burning eyes. "Because I fucking do. We're fucking perfect for each other. Tell me I'm fucking wrong, you stupid little bitch."

Ana gave in, and kissed her. She pushed her tongue deep into Leah's mouth, and Leah immediately sucked on it like her life depended on it. Ana's arms folded around Leah's body, and pulled her in, and she felt Leah's fingernails claw into the flesh of her ass, immediately drawing blood, and she moaned as the pleasure of pain sizzled through her. For a while she didn't even notice that Leah's tongue had pushed back, and that she was now sucking on her. She let it happen. She wanted her so badly. That soft, round body that had once been so innocent and full of goodness and compassion. She wanted nothing more than to invade it, penetrate it, taste it, make it shiver, make it come, make it scream—make her scream.

They separated only long enough to find the bedroom of the woman they had just killed and clear her bed of pillows and blankets and throw themselves onto it and into each other.

"You're fucking right, whore," Ana moaned. "It makes me so fucking wet when I see how fucking dead your eyes are—and it makes me so fucking wet when I think about how many people you will fucking rape and kill—and I want to be there for every last one of them!"

"Yesss!" Leah sighed. "Don't you fucking want me? Don't I make you fucking hot? Don't you want to make this little demon whore cum forever? Don't you want to see her cream?!"

"Yesss," Ana admitted. "I want it so fucking bad!"

"Then make me cum, whore!" Leah screamed. "Make me cum. I'll scream it for you, bitch. I'll scream everything you want to hear!"

And dove into Leah's folds and started sucking and licking, and Leah spread her legs wide, wide enough for Ana to be able to reach underneath and finger her asshole. Leah's shameless moans of lust made Ana's own quivering sex scream for attention, but she kept pushing hard against Leah's flesh instead, and Leah screamed with pleasure. "Yesss! My soul is dead! Oooooh.... yess! Yes! I gave it away and let it die! I'm free now! Yesss! I.... yesss!!! I'm willing flesh!!! No more fucking compassion! No more fuckin... oh yesss... yesss!!! Harder! Yes! No more fucking goodnesssss!!! Yesss!!! I'll kill for Her! Kill their souls! Make them serve! Make them Hers! Yesss!!!! YES! Harder, you bitch! Lick my fucking pussy! Lick me where you raped me! Yess! Fuck me!!! I'm her seedbed! I'm her whore! I'm her flesh!!! YES!!! WILLING FLESH!!! YESSS!!! YOU KILLED ME!!! YOU KILLED ME!!! MY SOUL IS DEAD!!! I'M HERS!!! I'M HERS!!! YESSS!!! YEEEEEEEEEESSSS!!!

Ana felt her body tremble, and Leah came into her face, legs closing around Ana's head with inhuman strength that would have crushed her skull if her body wasn't just as demonic as that of her evil, soulless sister. Leah gasped and panted and moaned, still shivering as the waves of pleasure slowly ebbed, and Ana could finally breathe. She drew in a deep breath and smelled the filth and the sex and the blood -- and the lingering scent of an innocent woman that would never sleep in this bed a again. It was wonderful. She turned herself over and laid down next to her hot, corrupted sister, and began idly stroking her own defiled fuck hole. Leah joined her, and for a while they simply lay there in silence, both of them quietly appreciating everything that had happened, lazily masturbating like the insatiable whores that they were.

After a minute, Leah scoffed as if she'd thought of something funny. Another short moment later, she spoke. "You know, I was so close to ruining it all."

Ana's brow furrowed. "What the fuck is that supposed to mean?"

Leah shrugged almost sheepishly, but when she spoke there was cruel pride in her voice: "I know how to cast a major annihilation spell."

Ana jumped upright in bed, eyes wide. "Was that what that was?! When I held you down to claim you? You were going to--?"

Leah grinned. She hadn't stopped stroking herself. "Yep."

For a moment, Ana was entirely speechless. A surge of adrenaline burned in her throat as she realized how close they had truly come to losing, and the animal in her wanted to lash out in desperate fury. She looked at Leah, and the seething hatred in her heart was enough to set the world on fire. She wanted to rip out her throat and let her choke on her own blood as punishment for ever having dared such a thing.

Except, they had already done that. They had already killed her. It was over. It was done. They were safe. They had won. The adrenaline ebbed, and the initial panicked rage in Ana's stomach gave way to a feeling of cruel satisfaction. She looked at Leah. "You were really going to detonate your own astral essence to save the world?"

Leah smiled, and Ana could tell that Leah felt the same contempt and the same cruel satisfaction. "I was moments away."

Ana's pussy tingled as she remembered the moment. "Poor little Leah came so close," she said, and teasingly pushed a finger past Leah's already busy digits and into her seeping cunt. "But then we raped her and killed her and made her serve."

"Wasn't I a brave little soul?" Leah asked, voice dripping with sadistic joy, and Ana felt Leah's pussy convulse as her sister began stroking harder.

"So brave," Ana mocked.

"So selfless," Leah added.

"So pure," Ana spat.

"So fucking dead," Leah hissed with delight, and kissed Ana. Their lips parted, and Leah eagerly welcomed Ana's invading tongue as her hands slipped out of her cunt and instead found Ana's breasts and the small of her back, violently and greedily pulling her in closer. Their flesh burned hot, and Ana felt Leah's sizzling anchors prick her flesh as her sister's heavy tits pushed into her own. Her pussy squirmed with hunger. She wanted her again. She was so fucking hot. Ana pulled away from Leah's lips to groan in a low voice. "Yesss," she hissed through gritted teeth. "Why don't you show me again just how thoroughly I killed her and lick me where I birth the Mother's demons?"

Leah pushed her lips hard against Ana's, then drew back with a wet noise. There was a wicked smile on her lips. "What do you mean, 'you' killed her? I did! I gave up my soul! I killed her!"

"Shut up and just make me come, you fucking whore!" Ana moaned.

"Say 'please'."

"Fuck you. I know you want it!"

"Fucking make me!"

Ana hissed and pushed Leah over with a furious growl, and Leah fell beneath her, and Ana grabbed her wrists and pinned her down and kissed her again, cunt throbbing with desire. "You tried to fucking kill us, you bitch. Lick my slit and pray that I don't make you suffocate on it! Submit and fuck me! Fuck me hard!"

Leah's eyes were mad with desire, and she dropped all pretense of actually fighting back. "Yesss!" she moaned. "Use me! Suffocate me!"

Ana pushed her needy pussy into Leah's face and rode her violently, squeezing her pierced tits, moaning and hissing with selfish delight. Leah gasped and choked and groaned, but her fingers were between her own defiled folds and she fucked herself eagerly as she pushed her tongue into Ana's seeping lips -- and together they fucked in the name of their own selfish lust and desire, and they fucked in the name of the mother they served, and they fucked in the name of the wonderful thrill of knowing that every fucking moan and scream of pleasure was another way to betray everything they had once been. Another way to kill them!

They screamed as they came at the same time, their cunts boiling with ecstatic spite and hatred, and Ana felt her pussy quiver and buck against Leah's face as they both mewled and moaned in celebration of their filthy, shameless act of lust.

Ana flopped over, exhausted, and for a minute all they could do was pant and shiver as they lay next to each other once again, spent and filthy and glowing with remorseless satisfaction. It wasn't like their bodies would ever cool off now, but Leah seemed to appreciate the moment of rest, too. It might have been peaceful, but Ana knew that Leah's wonderfully evil mind was just as alive with the endless heat of the Mother's call as her own. There was no moment in which she didn't think about sex and violence. She was a hateful, soulless monster. They both were. They had created a sanctum with their rutting, and birthed a demonic aberration from the flesh and soul of an innocent woman, and celebrated their own corruption and mutual claim of ownership with the mother's communion!

It was so fucking good to be like this.

"We should return to the Mother," Leah said eventually.

"Yes," Ana answered with a sigh. "Our communion was much more involved than I'd thought it would be."

"It sure was," Leah said. "But this felt like it was overdue. I would've felt cheated if we didn't get to gratuitously fuck after everything that happened. Besides, if the Mother needs us, she can just take control of our minds any fucking time she wants."

"True, I suppose," Ana said, and shrugged, and relaxed again. After another moment of silence, she turned herself over on the mattress and looked at her corrupted sister. "That was fucking hot. You're such a good little soulless whore. Seeing you come like that is almost like seeing you die all over again."

Leah nodded, and smiled, and her eyes remained as wonderfully dead and cruel as ever. "And that's why we'll always be together, Ana. Because it makes me just as fucking wet as you. You can have me anytime you want. " She was so fucking hot. Ana smiled with her—and slapped her across the face as hard as she could.

"I'll take you whenever I fucking feel like it, whore," Ana said. "I don't need your permission."

Leah snapped her head back, and glared at Ana with utter rage in her eyes. Suddenly Ana felt a genuine pang of instinctive fear, untouched by corruption and demonic power -- the base, animal, impulse that still remained at her core alongside her rage and greed and lust. For a moment she thought that Leah might actually try to kill her, and succeed, even if Ana would be able to rip out her throat in return.

But the moment dragged, and nothing happened, and Ana's fear turned instead into a feeling of awe. She was in awe of just how much violence and cruelty lived in the black void of Leah's soul. Enough to truly scare her, if even just for a moment. 

Then, Leah's smile returned. "Yesss," she hissed and licked her lips. "Exactly like that. At least, until I'm strong enough to hold you down and rape you."

Ana licked her lips, already feeling her hunger and lust return. There was not an ounce of weakness left in Leah. No goodness. No compassion. No shame. No pity. It was the hottest fucking thing Ana had ever seen after witnessing the Constellation, and she couldn't believe how fucking lucky she was to get to experience this forever.

She did not love her. Of course not. But it was true what Leah had said: They were perfect together. There was no one else they wanted to abuse more than each other, and soon there would be no more difference in their corruption, no difference in their power. They would fight for dominance every day, and Ana realized that there was no way to lose that battle. Not with Leah. Because the loser would always kneel and serve between the legs of the sister they had once loved, and look up into the soulless eyes of the monster that they had become. Fuck yes!!! The only one that had lost were the filthy whores that had long since died—the whores of the Order that had lost their souls and died to become what they were meant to be.

The soulless monsters that were Ana and Leah kissed once more, rose from the ruined bed of a dead woman, and walked out of the unholy Sanctum they had created. They left behind the wonderful chaos and ruination that would soon befall every soul on Earth and made their way back to the epicenter of the events that had started it all, walking through the darkness of the moonless night, with only the stars shining overhead, cold and distant and uncaring. They felt the resonance of their Mother at their cores, pulsating and throbbing and ever growing stronger. Inside their wombs, their seeds were growing and squirming, just as ravenous and insatiable as they were.

They returned to the university campus, passing through throngs of rutting soul-servants, listening to the delighted hisses and moans of bodies and minds freed from the shackles of their filthy souls, looking into a sea of cruel and selfish eyes devoid of humanity and compassion, and smelling the aroma of sex and blood and sweat. And in the midst of the wonderful cacophony stood the Mother of Lust, their Mistress, wearing the body of a beautiful bright woman named Jordan that had died just like the rest of them. Ana and Leah approached her, first flesh-servants among many, their bloodstained hands intertwined in a cruel mockery of love and affection—and the Mother saw them, and smiled, and understood, and approved.

It was a beautiful night.
