[Brainwashing, Brain Drain]

Darkness permeated the deepest depths of a certain Warlock's abode. This was where she conducted the contracts that allowed her to control the demons at her command, and she had returned here each and every time she had managed to thoroughly drain her servants of everything they were worth. Making the chamber go deeper, yet deeper, with every successive visit. She wanted to establish a greater connection to the demonic realm, that way she could gain even greater servants.

Her name was Elba. Many refused to let her name leave their lips for fear of angering her, as she had eyes and ears everywhere. Those that knew better would refer to her as the Great Demonologist, whose power over demonkind allowed her to turn them into her own power. It was why her servants never lasted long, and why her skin had taken on a blue tint from how much power she had absorbed.

Of course with all that pride came a deep desire to show it all off. Elba's robes covered her entire body, and yet they were so dangerously see through that it was almost impossible to truly call her clothed. The only solid articles that covered her body were the chains that served to decorate her body like accessories. Though they were meant for much more than that, as they kept her power in check. For every chain that curled around her body, another limiter was placed on her body. Absorbing this much power from demons had left her with a severe case of power incontinence... And she didn't want to blow up yet another country out of sheer recklessness.

But even despite all the power in her fingertips, despite the way she could feel her long raven-colored locks of hair trembling as power poured through them... She wanted more. She wanted so much more. And that was why she would summon a powerful demon that could eclipse her own strength. With nothing but her blood as an offering, and the magic that was filling every inch of it... She would bring forth a devious soul that would follow her every word, her every command. After she had put that soul in their place as one of her servants. And once they started to stagger... Their power would be hers.

"Come forth." Elba said, her voice booming throughout the dark chamber as she flinched ever slightly from carving a small wound into her wrist. "Feast upon this sacrifice, and join me in the mortal realm, demon of great power..!" Her voice grew stronger and louder as the room started shaking, all while a deep pink circle started to glow underneath her...

The raven-haired warlock took a few steps back as she watched the circle illuminate the entire room, bringing light upon her blue-hued skin as well. She could feel the power brimming from the circle. It was the exact kind of power that she desired. She had consumed the powers of demons that represented every sin except for this one. Pride, Gluttony, Envy, Greed, Wrath and Sloth had all been tamed and made into her power... Now only Lust remained, and this demon would be the greatest one of all.

"My my..." A voice echoed as a shadowed silhouette slowly started to emerge from the center of the pink circle, the light slowly sinking into her darkened form. "A mortal dares call upon me? The great Mael? I thought your kind would've learned not to play with fire, after the last time I regressed your civilization with my schemes..." The voice chuckled, all while her true figure remained utterly obscured thanks to the powers at her disposal.

Despite this, Elba stood her ground and glared into darkness that encompassed the demon. "You'd be wise to realize what you're up against, Mael." She smirked, crossing her arms as her own power started to surround her. A myriad of colors, illuminating the room after the pink light had been absorbed by the demon. "You stand before the Great Demonologist, Elba. And you will obey my command. Especially after you've been soaked in the power of that circle!"

Yes. This was how she managed to bind demons to her will. The circles that served as the gate between worlds were booby trapped. You would be branded by her mark upon passing through, and then you would find yourself utterly unable to do anything except obey her every word. Because that was what she wanted. She wanted to see the most powerful demons squirm under her command, no matter what she told them.

Unfortunately, she had underestimated one of the greatest demons, as Mael finally disspelled the darkness that covered her by simply unfurling her wings. Through such a simple act, she managed to break the power of the circle... Because the darkness had been a protective shell. After it had absorbed the circle's power, she didn't need it. She just tossed it aside like she would toss aside a meal that she had drained dry...

The Great Mael was a succubus beyond compare. Clad in what could best be described as an armored bikini, demonic scales covered up her most intimate parts. While she was more than happy to show off plenty of her skin while protecting that which was most important to her, one of the parts of her outfit that stood out the most was the massive shoulderpads. These were a status symbol in her part of the demonic realm. And of course as one of the strongest demons in her realm, hers were the biggest and most ornate. Despite the obvious spikes.

But the part about Mael that stood out wasn't her erotic choice of clothing. No, it was the pink aura that eminated around her. Thanks to the circle's specifications, even if the power had been absorbed by the cloak of darkness that she wore just moments ago, it still allowed her to use as much of her power as possible. And the aura that manifested around her, taking the form of female wisps that stroked every little part of her red-hued body... It was meant for ultimate and absolute seduction. Nobody in her presence would be able to endure her for long.

"A Demonologist? In my realm, that's what we call the worst kind of human. The kind that should serve as nothing more than a breeder for our kind." Mael laughed, all while stretching one of her hands out to tempt the woman in front of her. "And judging by the way you've matured over the years... I think you'd do nicely once you're spitroast between two of the demons you've tried to control.

Mael's aura started to stretch out and around her arm as the wispy hands reached for the warlock. They wanted to give her a taste of what it meant to serve her. They wanted to show her that she had done something terribly wrong. Because she had called upon the greatest succubus in the entire demonic realm...

Elba scoffed as that pink aura was getting closer and closer. "Really now? Then you're sadly mistaken, 'oh great one'. You'll be licking my heel to show you much you want to apologize for insulting me, once I've claimed your mind as my own!" She shouted as the multi-colored aura, her own demonic powers melded together into one big stream of energy, shot straight at the demoness. Weaving around those despicable hands to reach the succubus' head, and making direct contact before she could have a chance to stop her.

Mael licked her lips as that light came right at her. Because the light was exactly what her aura needed to get as close as it could. The hands tugged themselves along the stream until they reached their destination, that alluring and sexy warlock who deserved to be nothing more than an obedient pet to her betters. One who couldn't do anything except for listen to the orders she had been given, and then carry them out to perfection. Not unlike one of the machines that the humans were so proud of last time she visited this mortal realm...

Their duel over who got to dominate who had now begun. Whether it was going to be Elba draining every thought from the mind of the disobedient succubus so she'd have an easier time claiming the rest of her power in the near future, or Mael making the warlock submit to the powers of her lust, utterly enthralled by her ethereal hands constantly stimulating her... It was a race against time for both of them.

Mael was the first to show signs of giving in, as she could visibly see her willpower being drained through the multi-colored stream. Maybe she really had been underestimating that warlock, if she was able to... able to... D-Do that kind of stuff. Not that she was going to end up a big empty headed bimbo with nothing between her ears. No, she was going to be the one doing that to her!

Elba let out a powerful moan as she felt those ethereal hands caressing her body. Playing with her most intimate spots. Her breasts and her pussy were ripe and ready to be toyed with. And she couldn't do a thing to fight against them. Because if she tried something like that... She'd be losing control over the stream that let her drain the succubus. If she let up on her offense, she wouldn't be able to put up a defense that would be great enough to save her. She just had to drain her faster!

Little by little, the dark room was being further and further illuminated as the powers that were trying to dominate one another grew brighter and brighter. The brain-slurping stream of pure sin from the warlock was getting deeper and deeper into the succubus' head, leaving her to slowly but surely grow stiff as if she was nothing more than a doll without a brain. And at the same time, the hands were jamming themselves into every single possible hole on the warlock, making her concentration dwindle with every passing moment as it felt so unfathomably good to be pleasured in such a fashion...

Elba trembled as she very nearly fell onto her knees. All because of the pink mist moving in through her ears. The ethereal hands made from the succubus' aura were playing with her thoughts. Kneading her brain. She couldn't do anything to stop them now. She'd be forced into an eternal pleasure loop before long... B-Because of Mistress' wonderful touch... hhaaaaahhh...

Mael didn't move an inch as her eyes rolled into the back of her head. It felt so good to have all of those hard thinkies drained from her brain. Now she didn't need to think. She just needed to stand there and look pretty for her mistress. She just needed to be an obedient brainless doll that did nothing except obey. That was her role. That was what she was meant to be. Nothing but an obedient slave that didn't think for herself...

The colorful stream came to an end as the thoughts had been completely drained from Mael's brain. But Elba was in no condition to take advantage of them. All that she could do was fall onto her knees and smile as she slowly but surely shuffled towards the succubus that served as her Mistress.

"A-Anything, Mistress... G-Give me a command to do anything you'd want..." The hopelessly enthralled warlock, whose eyes and skin had now taken on a pink tint to represent how much she had been dominated by that lustful aura, just watched the unmoving slave with expectant eyes. She wasn't going to do anything without an order. Only silently enjoy the way that the aura stimulated her. She wasn't allowed to cum, but she could enjoy the endless edging experience. Because that was what she was given by her Mistress. She had to savour it.

Thus, both one of the greatest warlocks, and one of the greatest succubi, became forever locked thanks to the end result of their power struggle. And if somebody were to find them like this... It'd be easy to use the two mindless slaves as toys.
