[Corruption]

“You’re keeping pace, Kairi.”

The words of Master Aqua, the woman that had been through hell before returning to the Realm of Light, echoed through the pink-haired girl’s ear as she dematerialized her keyblade. All while a smile made its way onto her face.

“It’s all thanks to your training, Master Aqua. If not for you, I’d still be the same weak girl that couldn’t save her friends.” Kairi said, bowing respectfully before her senior and teacher. This was her way of catching up, to train with the one Master that had been through it all.

Aqua nodded and smiled back. “It’s important that you cherish them, so that you keep them in your heart.” She said, putting her hand on the girl’s shoulder. “But it’s also important that you remember that they’re still people. They may do things that you think are… wrong, to put it as bluntly as I can muster. But as long as you trust in them, and talk to them about it, everything will work out.”

“I’ll remember that, Master Aqua.” The younger girl said, smiling a little. “Did you do the same for your friends?” She asked, curious about the older woman’s life and past. After all, while they had fought alongside one another in the final Keyblade War, they weren’t close at all. She still wished to learn so much more about her and all the others.

The Master nervously laughed. “Do as I say, not as I do.” She said, letting it be laid out as simple as that. “Now, to finish off our session for the day, I’d like you to spar against me. I’ll refrain from using too much magic, all you need to do is force the Keyblade out of my hand.”

“I got it!” Kairi cried out as she manifested her Keyblade, brandishing it… Only for her eyes to widen as her heart started to thrash against her chest in pain, her blade nearly dropping to the ground in the process.

Aqua quickly started turning around. She knew that Princesses of the Heart, especially ones that became Keyblade Wielders, were particularly sensitive to large quantities of Darkness. But this..? They had defeated Xehanort, and the Heartless shouldn’t be as dangerous as a result. So what was causing her this pain?

The two Keyblade Wielders would realize what was causing the girl so much pain, as a portal of Darkness opened right in front of them, leading straight into the Realm of Darkness. And from within, a single figure stepped out…

At a glance, it looked more like a Nobody than a Heartless, given the creature’s more humanoid shape. But the shattered looking Emblem on its chest made it clear that it leaned closer to Darkness than Nothingness. And yet, that wasn’t the thing that stood out most about it.

No, it was the extremely feminine shape to its figure that ended up standing out much more. It was like an exaggerated version of Aqua herself, to the point where it seemed to have elongated hair-like tendrils reaching down towards its hips. Combine that with the fact that it seemed to have a bosom bigger than the Master herself, and an utter lack of anything close to ‘clothes’, and it seemed like some sort of exhibitionist more so than a Heartless.

“That… that thing is…” Kairi panted, slowly grabbing her Keyblade as she brought herself into a combat stance. She didn’t want to look weak, not in front of the woman that was teaching her to fight better. “It’s just Darkness, from head to toe.”

Her blue-haired Master manifested her own Keyblade. “Not just that. It seems like the Realm of Darkness took a liking to my body, for the little while it had control of me.” She said, as a flame lit at the tip of her keyblade. She wasn’t about to let that thing, that mockery of her life, stand against her and live.

The Heartless seemed to giggle as it slowly brought its hand across its face, forming a mirror-like Mask with the shattered Emblem embedded within. As if you saw yourself with the Darkness’ influence laid on top of your reflection, should you look into it…

In fact, that’s exactly what Kairi saw as she looked at the mask. She could see herself, taking on a form not unlike the Heartless in front of her. All of her good, stripped away and replaced with a blackened form that could only harm others and devour the worlds…

She could feel her legs trembling. She could feel her heart pounding. She could feel something drooling, but she wouldn’t be deterred. She’d fight!

“Go away!” She cried out as she leapt straight towards the Heartless, who didn’t even react to her attack as it was coming straight at it. It just ‘stared’ at her, letting that mirror peer straight into her…

Aqua was quick on the uptake, as she tried to reach out towards the reckless Princess of Heart. But she was too late, the second that the Keyblade made contact with that mask, a dark light filled the world around them as it started to crack.

From the cracks on that mask, the emblem slipped out. Every single little shard of the shattered emblem firing off towards the pink-haired girl, slipping onto her face and causing her more pain in the process as she fell to the ground.

“Kairi!” The Master shouted, gritting her teeth as she fired off a Firaga spell straight at the Heartless’ body. Since it didn’t make contact with the dangerous area, it managed to just turn the feminine Heartless to cinders, leaving her to deal with what just happened to her student.

Aqua turned her attention towards Kairi, only to flinch as she noticed that the girl’s face had been utterly ruined by the additions of those shattered marks covering her cheeks, her eyes and everything else. It was like she was being worn by the emblem, messing with her features in the process.

It wasn’t just wearing her in the cosmetic sense either. With her heart still pounding in pain, she wanted it to just go away… And it did, as she started to giggle…

Slowly but surely, the Princess of Heart’s body started to turn the same pitch black as a Pureblood Heartless. The same sort of color that the Heartless that just burned to pieces had.

Why should she worry about something as silly as fighting for her friends, when she had so much to devour? Why should she worry about other people when she could just be herself? She never bothered asking those questions, but the Heartless Emblem was more than happy to force them through her head.

And when she didn’t have an answer, it imprinted one upon her. She shouldn’t be worrying. She should be eating. Eating until every world had been turned into part of the Darkness. Whether it was the world itself, or its inhabitants… She’d eat them all…

Kairi slowly stood up as her Keyblade disappeared, her body having taken on the exact same looks as the Heartless. Even her clothes had been torn apart, leaving them as little more than shreds on the ground as she looked straight towards the blue-haired Master. All while her face turned into the same sort of Mirror as the one that had converted her.

Aqua pointed her Keyblade straight at her pupil. She knew that there was still good inside her heart, because the Heartless wouldn’t be able to just convert her like that. It wouldn’t be able to turn her heart into nothing more than a puppet for the Darkness. She just had to strike and get it out.

Unfortunately, the converted Princess of Heart was faster than she expected. Before she managed to swing her Keyblade or even launch a single spell, the mirror-masked Heartless dashed towards her, pinning her to the ground as she was forced to look at her own reflection with the shattered Emblem layered on top.

She tried to struggle. She tried to break free. All that she could do was stare straight ahead, while the pseudo-naked Heartless wrapped her legs around her thigh, forcing the two together…

“W-What are you…” Aqua muttered as she felt a knee grinding its way into her hole. The pleasure that pierced through her was unlike anything she had ever experienced before. It felt like she was forced atop of the highest clouds, her heart smashing against her chest from the sensation…

The more she looked into that mirror-like mask, the more the Heartless that had been Kairi started to play with her. Tearing away her clothes to get to her breasts, fondling them to bring more of that pleasure into her. Squeezing them, playing with them, all while she forced her knee deeper into the drooling hole below.

It felt too good. Was this what she felt after the Emblem sank into her? Was this why she had fallen and turned into a Heartless, this powerful pleasure..? It if was, she totally understood. She wouldn’t be able to resist. She couldn’t resist at this very moment…

Aqua let out moan after moan as she was stripped further and further until not a single garment covered her body. The only thing that remained atop of her, was the Heartless trying to force the pleasure out of her. The same Heartless that no doubt wanted to stain her heart in the same fashion that it had stained her pupil’s.

Slowly but surely, Darkness started to drip from the blackened and mirror-masked Heartless’ body, each of the droplets sinking into the Master’s form. She could feel it trying to worm its way through her, trying to pull at her heart.

And it was working. Because every time she tried to stop it, she felt another grope or another shove from the knee, leading her resistance to be melted away by pleasure. In fact, the Heartless didn’t even need to be rough at this point. Her body was already picking up on the way it was training her to respond. Any grope would force a moan, and stop her thoughts from flowing together into something coherent.

The Darkness continued to traverse up Aqua’s body until it had converted all of her beautiful bright skin into nothing but the deepest and darkest blacks, leaving her just as colorless as the Heartless atop of her. It was less like she was naked, and more like she was covered in a massive layer of living paint. That’s what it felt like, and it only made her assets more sensitive.

She could hear a voice. A faint, but compelling voice. One that told her to devour. One that told her to reproduce. One that told her to proliferate. So many statements from the same voice, none of them coherent. And yet she understood all of them, as if they were integral commands that she had understood for such a long time.

As she accepted the voice into her heart, she could feel herself slipping away. She could feel her kindness, her very self, sealing away inside all of that Darkness. And on top of it, a new form would emerge. A Heartless, wearing her like she was nothing more than a core to power it.

Her capture and her imprisonment were both solidified as the mirror mask formed on her face, the Emblem still embedded within. Anybody that looked into the Mirror of Desire would find themselves falling, turned into a horny host for the Darkness to wear. Both of them had fallen victim, just like the one that had served as the host to the one that converted Kairi…

But before the two would go convert their fellow Keyblade Wielders, they had something else to indulge themselves in. Because as Heartless, they had needs and wants themselves. Whether it was to devour Worlds and Hearts…

Or to ‘devour’ one another, as they pussies started to grind up against each other. Pitiful moans echoed from their ‘lips’, as the two Mirrors of Desire enjoyed themselves.

The Worlds would fall. Fall to pleasure. And be devoured, by the Mirrors that brought out their inner lust...
