[Brainwashing, Brain Drain, Mutual Loss]

"Soon enough... Soon enough, they'll all be mine. My precious toys, swallowed by my love and converted into such loyal souls..."

Madame Rouge, formerly known as Kurohime of the Jigoku, was a devious Demon that took her time carrying out her schemes. Rushing towards her destination would just be sloppy. For now, she patiently dismantled her opposition. Turning those disgusting cybernetically-enhanced 'Tengoku-Nin' into much more appropriate forms. All thanks to the youngest member falling for her charms and willingly becoming a tool for her to use and abuse...

Yes... Little Ao, stuck in the machine that allowed her to control the cybernetics of any Tengoku-Nin that got hooked up to her. She would have to reward her for her service in the near future. Perhaps even let her transcend humanity and become her kin... But only after all of those foolish girls had been converted completely. Only then could she afford to get rid of the asset that let her have one over them...

Still, there was one thing that was eating away at the back of her mind. The Tengoku-Nin weren't the only ones that were out for her head. There were many more dangers lurking around every corner. Other heroic figures that wanted to make sure that she paid the price for what she had done, and her former allies also wanted a piece of her pie. Honestly, it grew to be rather exhausting, knowing that she couldn't draw a single breath without getting into more trouble...

"Mistress Rouge, like, I found a cutie!"

Not to mention, she had to deal with the occasional intruder. Intruders that were thankfully caught by her toys, so she wouldn't have to directly interact with them unless they were a threat...

Madame Rouge turned towards the doors leading into her personal quarters, watching as her dear Ruby dragged in a mysterious figure. One that she didn't exactly recognize, despite the extensive amount of cybernetic modifications that had been performed on her body. By all accounts, she looked like one of the higher ups within the Tengoku-Nin, yet at the same time she felt so... Inexperienced. Which would probably explain why her maid had been able to capture her.

"That's right! I am a cutie! That's why you should let me go, so I can deal with your Mistress! She's been encroaching on my turf for far too long!" The girl being pulled along cried out, as she struggled against Ruby's powerful grip. So eager to announce herself as an enemy, while being at the mercy of one of the Madame's minions...

Madame Rouge chuckled slightly as she put her hand on her cheek. "Cutie might be stretching it, Ruby. You seem to have dragged some trash into my quarters. You know what I do to maids that actively cause problems, yes?" She used such a sweet tone, while at the same time using such antagonizing words...

Words that went right over Ruby's ditzy head as she just giggled and lifted the girl up, patting her on the head. "But, like, she wanted to try and hack me! And she got all sparky, so I thought you'd like her!" Such concern from a ditzy girl that had once been such a dangerous enemy... Ah, she had been reprogrammed to be so useful, despite being so useless at the same time... How adorable.

"I am not trash! And I didn't get sparky, your firewall was just more extensive than I had planned for!" The technologically enhanced dummy said as she wrestled herself free from the maid's grip, dusting herself off as her pride practically poured off her figure. "I am Techmistress! And you've been strongarming yourself onto my turf, Demon Lady!" She declared, pointing straight at Madame Rouge in such an overtly dramatic fashion...

Madame Rouge chuckled. Ah, yes. She had heard about Techmistress. More so about the endeavors of her ally, which allowed the foolish little girl to amass quite a lot of power and influence despite being dumber than a box of rocks. "I have a name, dear. But if you wish to stop me from gaining more control over the region, I know what you can do."

Techmistress blinked for a second, before grinning and laughing. "I see, I see! You're much more reasonable than I expected, Demon Lady! Now, what must I do to make you go away? You're interrupting my fun with Caretaker!" She didn't even think about how this could be a trap. Why would she ever think of something like that?

Madame Rouge snapped her fingers, and the floor underneath Techmistress opened up. Causing her to fall straight into a very cushy chair. A chair that was connected to a much greater piece of machinery, which seemed to house somebody. Not that anybody but Madame Rouge could actually identify who was inside it... Well, Ruby kind-of could, but her mind was too flimsy to properly understand that it contained one of her former kin.

"You just sit tight in that chair, and we'll have a nice, long discussion about how things are going to be from now on. Is that okay with you, Techmistress?" Madame Rouge's words were beyond condescending, while also dripping with sarcasm. Not that she expected either of the two girls to really pick up on what she was saying.

Techmistress smiled as she heard those words, and nodded rapidly as she leaned back in the nice chair. "Very well, very well! Perhaps we can even form an alliance, then it wouldn't be strong arming onto my territory! In fact, I think Caretaker would like you! You're very nice and smart, Demon Lady, and Caretaker always did say that she wanted somebody to match her intellect, so she could-"

She didn't finish prattling on and on about her partner. All thanks to a set of wires that quickly started to connect to her body. Sinking into the exposed mechanical parts of Techmistress' body, really integrating into her system and making sure that she was being properly contained on the chair...

Being hooked up to the device felt a lot nicer than Techmistress was probably prepared for. Not that she was ever prepared for any of the treatments that she was put through. Whether that treatment came from Caretaker, who carefully wiped her mind of every single procedure so she wouldn't even think about how horribly she was being treated, or now from this nice demon lady...

"There. She might not be a Tengoku-Nin, Ao, but you're free to convert her just the same. She'll make a great maid, once you've finished her off." Madame Rouge said, snapping her fingers once again. A snap that reached all the way into the containment unit that served as part of the machine...

"Maid? What-"

Techmistress tried to cry out in protest, but it was already far too late for her. She had been hooked up to the machine, so she really should've seen this kind of betrayal coming. Especially as she started to feel all sorts of shocks pouring through her, causing her to cry out again and again, over and over...

The cries were potent and filled with pure arousal, with her body unable to move an inch on its own thanks to how she had been hooked up. No matter how much her body wanted to move, no matter how much she might be wanting to escape, there was nothing she could do when faced with this potent shock therapy...

"Oooo, she's squirming and squirting, Mistress!" Ruby giggled as she watched the captured villainess' seat get nice and wet from all the juices that were pouring out from her hole. It was a very pretty sight, one that made her drool a little. Not just from up above, as the thirst that had been programmed into her mind caused her to leak down below as well. All while she kept on watching with eager eyes, happy to just watch and watch...

Madame Rouge giggled as she watched as well. She knew that Techmistress seemed like an easy target for her manipulation, given the way that she behaved. But this? This was on a completely different level. It amused her greatly, to see her so quickly fall prey to what the machine was able to do. If this kept up, her identity would be erased before long. And after that, it was up to her to pick an appropriate one... Perhaps she could use a pet, considering how little actual capacity for thought was available to the villain.

Techmistress certainly tried to fight back against what she was going through. But her attempts to struggle, her attempts to fight back and be able to do anything... They just fell flat, because of all the intense pleasure.

Her delusions of grandeur, vanishing before her very eyes. Draining into her tits and down between her thighs, as she felt the warm shocks pour through her bosom to distract her even more than they already had been...

Her memories, her wishes, her will, all turning into nothing more than sticky cum pouring out from her pussy. All while she started smoking a little, due to how badly she was falling victim to what was happening to her...

By the time her face was nothing more than a stupid grin, the machine started to power down. And Techmistress was left lying there, her eyes completely empty. There was not a single thought left inside her head. Not that she ever really had any thoughts in there. The thoughts inside her head were a formality granted to her by her Caretaker...

"My. I really did expect more from you. Not much more than this, but every single thing inside your head has melted out through the gap between your thighs..." Madame Rouge muttered, as she just closed her eyes and shook her head. "Nevertheless, we still need to fill that empty head with something. And..."

Her gaze turned towards Ruby, who was still watching... And idly fingering herself. As always. What a naughty yet absolutely ditzy girl. But that was why she loved her. Why she adored one of her favorite toys.

"Ruby, dear. Hold still for a second, will you?"

Ruby listened to her Mistress' words, and stood perfectly still. All while hearing the sound of her fingers snapping. All while she felt the machine plug into her crotch for a second, causing her to gasp...

And as it pulled away, her uniform's skirt had been tented. All thanks to the wonderful shaft that had grown in the place of her pussy. One of the benefits of being mostly mechanical was that her parts could easily be switched out with a few jolts, leaving the loyal maid with a wonderfully thick shaft...

"Oh my! Can I use it, Mistress? Like, I wanna fuck the cutie!" And already, the hormonal benefits of having a cock like that rushed straight into Ruby's head. She was so, so eager to just cut loose...

A single smile from Madame Rouge was more than enough for her to know that she could. Prompting the redheaded maid to giggle with glee as she mounted the thoroughly drained Techmistress...

And slam her cock straight into her vulnerably wet pussy, the moans of one drained slut and one ditzy futa to echo out as the two partook in one of the simplest acts in history. Pure, lust-filled intercourse...

Madame Rouge smiled as she watched the two go at it, as she quietly turned back towards the windows that overlooked the city. Gleefully amused by this turn of events. Not only had she dealt with a potential rival, as weak as she really was, but she had also given her maid a new toy for the time being. Once Ruby was done with her, she'd have to upload a brand new personality into her... Perhaps Topaz would be the right fit for her?

As the devilish dame thought to herself about where she would go from here, she neglected to notice the sound of something metallic overhead. Ignoring the fact that somebody seemed to be sneaking into her home. Especially as it came to a stop, right over her head. Where she could be most vulnerable...

Not even as she heard the sound of a grate falling did she pay any mind. She merely stood there. Watching the city, as a mechanical woman landed behind her. A woman with little actual emotion on her face, even as she radiated hatred in the form of intense heat...

"Goodness. I heard you were overprotective, to the point of potentially ruining your own charge. And here you are, trying to cook me before you even give me a chance to gloat." Madame Rouge said, as she gazed over her shoulder. Gazing straight into Caretaker's eyes, smiling from ear to ear. As if she knew that she would come out on top.

Caretaker 'smiled' in turn, as she firmly wrapped her arms around the demon. "I do not give chances to those that harm my dear, you know." Her tone was mechanical, yet you could almost taste a hint of genuine care in her voice. Not that it was easy to tell, considering her nature. "Struggle all you want from this point forward. Your brain will cook even faster in response to your struggles."

A chuckle left Madame Rouge's lips. She was a Demon. The great Kurohime. Though she had cast away her name to try and infiltrate this world that much easier, that did not stop her from having much greater resistance to attacks like these... Attacks that were to melt her brain would have to really... th-thoroughly...

The sound of bubbling echoed through her ears, as Madame Rouge's expression started to waver and a bit of drool started to run down her chin. She was trying her hardest to keep herself together, but it was clear that she wasn't doing a very good job at it. Prompting her to gasp and struggle more and more...

Which just made the sound intensify, and the happy feelings that came from having her brain cooked slowly pour through her. She could feel her thoughts melting into a soup of pure pleasure, especially as she managed to turn around and face Caretaker...

Caretaker was still staring with that plain expression. But the heat that poured from her body was definitely intensifying. Partly due to the rage she felt at having her dear Techmistress abused by somebody that didn't have permission to play with her... And partly out of amusement at the Demon falling prey to something so simple as this.

"What's the matter, 'Madame Rouge'?" You could almost taste the condescension in her voice, even if she was a mechanical being. "The look in your eyes made it seem as if you believed you could endure this. So why are you starting to drool like a common slut?"

Madame Rouge let out a moan, not unlike the slutty moans that were coming from the machine where Techmistress was still being fucked by Ruby. She... She needed to regain control of the situation somehow. Before she ended up even more brainless than those two. Before she ended up cumming everything out...

Her thoughts were beyond scrambled. They were completely and utterly melted. What options remained? What could she still do to maintain her grip on the situation? Several ideas poured through her mind as she tried to think, but only one option came to mind. One devilish and absolutely dangerous option...

The struggling Demon wrapped her arms around Caretaker... And kissed her. Right on her plain metallic lips.

Almost immediately, the heat inside her was transferred back into Caretaker... No, not just transferred. Amplified. She was returning the cooking with a gleeful look on her face, as her eyes rapidly turned into hearts from how intense all the heat inside her had become...

"H-Heat... r-rising..." For once, Caretaker was losing control of the situation. Her inner circuits were being melted, just like Madame Rouge's brain was turning into nothing more than juices pouring out of her pussy...

The worst part was that she couldn't struggle. Not just because of the heat that would intensify further and accelerate her melting, but because the parts of her chipset that controlled her motors had already malfunctioned. Forcing her to stay here, with her arms wrapped around the demon that was trying to make her melt...

"Ehe... EHehehhehe..." Madame Rouge giggled as her eyes turned pinker and pinker, to show just how far her mind had fallen. "Ruby was waaaay wrong... You're the real cutie..." The proud demon was this close to being completely gone, but not gone enough to the point where she couldn't taunt the mechanical caretaker...

Caretaker, sparking and on the verge of a complete shutdown of personality as her formerly expressionless face started to curve into a slutty grin, giggled a bit as well. Before kissing Madame Rouge back and moving her hands down onto her hips instead of hugging her close...

As soon as their lips met, and their minds melted from all the heat running through them, a powerful climax managed to pierce its way through both of them. Both Demon and Robot let out gleeful gasps and screams, as they collapsed onto their knees. Still grabbing onto each other for support, and out of even greater lust that kept on pouring through them despite how they had managed to get rid of their minds by cumming...

And their scream was matched by Ruby, who ended up cumming straight into Techmistress' vulnerable pussy. And yet even after that, she ended up pulling out and giggling a little, because she didn't feel like she was done. Prompting her to turn towards her Mistress for more guidance...

Only for Ruby's cock to tremble as she gazed upon the two sluts locked in a hug, causing her to giggle way more. Well, if Mistress was going to let her fuck her and fuck another nice looking lady...

Well, who was she to turn down this fun turn of events? Like, maybe she could be the boss now, since everyone was so brainless?

Ehe... Ehehehehe...
