[Goth TF, Filth, Corruption]

"Ahahaha! Finally! Took long enough to get in here, but I'm in!"

A loud and powerful laugh echoed through the world as a dark-skinned lass touched down on a world that she had coveted for a long time. Or, well, touching down would imply that she was an invader from outer space. It would be more appropriate to say that she had managed to slip inside, especially thanks to her ethereal nature.

She was Blair. One of the Creator's dear friends, and one that had been barred from entering the world of the Natura Couleur. Mostly because of her interests, and how quickly they could make everything spiral out of control. Considering the last few worlds that Blair managed to slip into, the Creator was well in her right to avoid letting this happen to one of her most precious worlds.

And yet here she was. Right inside the world that she had been specifically told not to invade. The birds were chirping, the sun was shining down, and the heroes in this world were ready to strike against any kind of evil that was going to manifest. It was the perfect kind of place for her to ruin.

But as much as Blair wanted to just cut loose, she didn't want to be too obvious. If she was, then she would end up... Well, the Creator would end up finding out about her antics, and then she wouldn't just get double banned, but she'd get used as a seat while that tired writer spent another ten hours writing a storm. Even for a pervert like Blair, this was not something that she was equipped to handle.

Which was why she had to try and figure out an alternative solution. If she couldn't be the one to transform the Natura, then she would have to appoint a proxy. Now, who could she use... Who could she use...

Blair's eyes lit up as she grinned, all while casually dropping straight down to the ground. She knew who to approach, the very same girl being not too far away from her current position. All she needed to skip around a little, and then...

"Hm? Who are you?" A redheaded girl, currently wearing a gentle blue dress that concealed her true nature, looked towards the dark-skinned girl that was practically barrelling towards her. Who was she, exactly? And why did she remind her of Tenebris when she looked at her? She didn't seem to have those dark traits that were characteristic of her minions or her victims, so why...

Blair grinned. She didn't need to say a thing. All she needed was to step close enough to plant a kiss right on that cute girl's face, so she was stunned for a time...

And then she shoved her right down onto the grass below, before slamming her ass straight onto that face. The mild fumes would serve to break her for a few moments, which would be more than enough for what she needed.

Now, to prepare for the girl's teammates to make their way here...

---

"So this is where Shiro went? I mean, I'da guessed it the moment the big castle appeared, but can't hurt to be sure."

"I'm sure. Seriously, Akane, there's no way it could be anywhere but here."

"It really is big, you know? How'd it appear from under our nose like this?"

"So what if it appeared all of a sudden? Back me up with your heals, Kohana, I'll smash it to bits!"

"Be cautious, everyone. We don't know what enemy we're fighting against. Stay close and make sure that they won't catch us off guard..."

The Natura Couleur had arrived not long after their ally had been incapacitated. And, frankly, none of them were prepared to see a giant gothic castle having practically sprouted from the ground. Even their greatest ally and the one that supplied them with power, Eclipse, did not understand how a castle like this could manage to sprout from within Equilibre. Which meant that they just had to fight to the best of their ability...

Natura Rouge, Araya Akane. Natura Vert, Kido Mana. Natura Blanc, Shirai Kohana. Natura Noir, Sakurai Kiko. Natura Bleu, Eguchi Aoi. All of them were united against their single enemy. All to save their former predecessor and current ally. Natura Arc, Shima Shiro.

Which was why all of them were sufficiently unnerved as soon as they broke their way into the castle's throne room, because that was where they both found the culprit... And the girl herself, who was currently laying on the ground, seemingly passed out from the kind of treatment that she had endured.

"Shiro! Wake up!" Rouge cried out as her body started to get covered in flames. All while she cracked her knuckles. "You, over there! You did this to her, didn't you?!" She shouted, pointing towards the dark-skinned individual currently sitting on a really spiky throne in the far back...

Blair, having taken up a seat on the throne, nodded a little as she stretched. "Mmmmmhm. That I did. You know, she's a great seat. Kinda makes me wish I didn't stop using her, but I had to. Otherwise she wouldn't make a great enemy for you all." The black bitch on the throne laughed, all while snapping her fingers. "Get up, Blairtura Arc!"

Shiro trembled as she heard that command, causing her to cough and gasp. She didn't want to get up. She didn't want to fight against her friends. But what choice did she have? The gas that has been pouring into her system was practically puppeteering. She didn't want... She... She..:!

*BRAAAAAAAAAAAAAAAAAAAAAAAP*

All of the other Natura watched as their ally was forced to fart like her life depended on it, the noxious fumes flowing out of her rear as it quickly sank back into her body. Transforming her outfit into a crude mockery of her transformed uniform. A black-shaded leather top and an incredibly small set of shorts that were both on the verge of snapping off, which complimented her brand new shade of dark skin and her dark-ginger afro that made her look almost like a copy of Blair in her own way...

"Okay, that's just way too gross." Vert muttered as she drew her daggers. "Everyone, stay out of her range! If her farts were able to turn her into that kind of bitch, then we don't want to even come close to getting touched!"

Listening to their tactician, the Natura Couleur all spread out and kept their distance, with Rouge and Bleu taking charge of the offense thanks to their extra firepower. Flames and raindrops spread around them, as each of them lashed out and started to attack.

"ROUGE CROSS!" "WHIRLBLEU!"

On one side of Blairtura Arc, a beam of pure heat was being shot at her. On the other, a horizontal whirlpool that not only shot out at her, but also started to pull her in. The opposing elements were strong, and if they managed to clash against her body, there was no telling what it would do to her...

"Get away... Get away before it happens to you too!" And with what little control Arc had over her body, she tried her best to stop them. All while a gassy barrier started to form around her, courtesy of the lingering smell from her ass. All while her body reached towards her ass and pulled out two matchingly filthy blades...

Vert's eyes widened. "BLANC! BARRIERS, NOW-"

"Blair Blast!" *BRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAAAAAAAAAAPPPPPPP*

Arc slashed against the two encroaching attacks, before the order could be given to prevent any damage from reaching the two Naturas. And these blades made of filth not only immediately exploded, but they converted the attacks into more filth. The fiery fumes of an extra large burst of gas, as well as the swirling fumes of a fart that just wouldn't go away. Both quickly flew back towards their respective Natura, to try and defeat them with their own techniques.

Rouge's eyes widened, but she was quickly knocked out of the way of the blast thanks to a timely save from Noir, who had put all of her strength into her legs to allow her to carry out that save. Which meant that one of them was out of range, but the other...

"S-Sorry, Bleu!"

Blanc had been ever slightly too slow, and instead of blocking out the smell... She had trapped Bleu inside of her barrier together with the smell. Forcing the blue-clad heroine to fall onto her knees as she was being suffocated by the intense fumes. They were... They...

Bleu's eyes widened and slowly grew nice and dim. The fumes were too much. Not just for her, but for anybody that would dare try to fight back against them. She knew this. She always knew this. And yet she tried to act like she could fight back against them. How absolutely foolish of her. She should just give in... She should just accept that the farts were better than her, and that they were her whole world...

The barrier cracked as the fumes fully absorbed into Bleu, as her entire color scheme turned black and gothic. The farts hadn't just overwhelmed her with filth, but they had corrupted her very soul. She didn't see a point in trying to fight against them. If anything, she should spread them and let their despair claim her friends. "Fartura Bleu... Now come, everyone... Come and smell them with me..."

Vert grit her teeth. Alright, so not only was the bitch in the back able to completely convert Shiro into a copy of her, given most of the traits that were shared between them, but their farts were able to erode the will that kept them all going. Great, just great. "New plan! Everyone, I'm giving you a copy of me! Make sure that they get inside you and give you proper air circulation! Don't let even an inch of that gas flow into yo-"

Before Vert finished giving orders, or even making the copies that were supposed to save them... Arc had already slammed straight into her, ass first. All while Arc let out a soft giggle that made her sound just like the bitch on the throne...

"I told you to get away... And y'dummies didn't even bother. So now I'm not gonna hold back!" Arc grinned, as the look in her eyes now completely replicated the look in Blair's eyes. They were practically the same, as Arc allowed her inner bitch to take control. "C'mon, Vert. You stupid bitch, why didn't you just listen?!"

Vert couldn't respond. Not with an ass currently stuffed in her face. Nor could she help the others, as all of that ass was making it harder to think. They really needed her help too, as Bleu was... Bleu was...

The green-haired heroine's eyes rolled into the back of her head as she smelled more and more of that foul scent. It was overwhelming. It was too much. She didn't want to give in to it. But what was she supposed to do? What could she possibly do? All she could do was just lie there and let it soa-

*BRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP*

Her fate was sealed as Arc let out another intense fart. This one sank straight into Vert as it turned most of the color on her body black. Only her skin tone remained nice and pale, to emphasize how much of her will was left. She was completely and utterly subservient to those despair-inducing farts that were going to make the world a better place... Ah... Why was she ever trying to think, when those farts should be doing all the thinking for her..?

"Vert! Damnit!" Noir cried out, only to get shoved out of the way by Rouge as the red-haired heroine narrowly burned away a torrent of filthy fart-water that was heading straight for them. "We have to do something, Rouge! Blanc!" She tried to take up the mantle of somebody that could lead them, but all she had was her muscles and her feelings towards her friends.

Rouge nodded, before taking a deep breath. "Blanc, I'm giving you everything! Make sure that you get one of them healed!" She shouted, as she transformed herself into one big flame, all while the dark-skinned white-haired girl came running towards them while covered in a barrier.

Blanc grabbed ahold of Rouge's flaming form and pushed it up against her, letting her healing power go into overdrive as she healed herself to the point where the flame became part of her. Turning her colors partly red as they fused together, at least for the time being...

With two Naturas turned into Farturas, and another turned into Blairtura, things were looking grim. But as long as they could fight, they wouldn't back down. Not while their friends had been corrupted like this..!

Blair was rubbing her hands together. Heh, it felt so good to corrupt them all. And they were all perfect. Sure, the goths weren't nearly as black as she liked them, but their asses were beyond beautiful. God, she could just stuff her face right in between and huff the fumes for hours...

That thought transferred to her converted minions, as each of them grabbed their asses and grinned in tandem. If one of them could heal and absorb things, then what would happen if she tried to heal away their stink?

Blanc noticed what was happening, and quickly stepped in front of Noir. "As soon as my barrier falls, Noir! Go punch the living daylights out of that girl on the throne! Please!" She cried out, all while letting her barrier grow thicker. She wasn't going to let her dear friend get broken by all this gas. Not when she could still help her!

*BRAAAAAAP* *BRAAAAAAAAAAAP* *BRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP*

Three intense farts flowed out of the three minionized Natura's asses, each worse than the last. Each almost flying straight towards the barrier, the intensity of the smell smacking straight against the barrier. Even her healing power wouldn't be strong enough to hold up against it. But she did what she could. She healed it as much as she possibly could, all while letting out powerful cries...

The power of Rouge was making her heals even more powerful. But at the very same time, it was making it harder and harder to think. Not because she was being degraded, but because the sheer intensity of her own power was overwhelming. Especially since you could visibly see parts of her body burning the more she used her power. And since she was burning, she had to heal herself more...

Which served to be her downfall. The farts that were slamming against her barrier just needed the slightest crack to slip in and get healed into her body. And once it was part of her, the farts could merge with the flame inside of her, quickly turning it just as filthy as the farts that were trying to aggress on her... Right up until...

*BRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP*

Blanc's eyes widened as she suddenly farted, to the point where she couldn't stop it from wrapping around her and sinking into her. How was she supposed to fight back against such a sudden spew of fumes? Much less one so farm, so comforting, so... so...

The barrier fell, revealing not only Fartura Blanc who was still in the process of looking as gothic as possible... But also Fartura Rouge, who took form after slipping right out of that ass. Taking form as all the gas solidified, causing the gothic corrupted heroine to lick her lips in delight...

"No way... Akane, Aoi, Shiro, Mana... KOHANA!" Noir cried out, the dark power inside her causing her veins to grow extra black with all the strength pouring through her. She was going to knock them all out, knock them back to their senses! Even if they farted in her face, she would break them back to their original selves!

At least, that's what she would've done. Right before all of the farts that had slipped out of Blanc, the ones that hadn't been used to convert her into a Fartura, coalesced into a barrier around Noir. There was no way that she was going to break out of that one either, a simple punch just sent the farts through her body. Something that she unfortunately tried, causing the poor heroine to cry out in a displeased sense of pain.

Blair laughed and clapped, as all five of her converted Natura kneeled before her as soon as they heard her clapping. "See? A few farts, and they're completely submissive. Well, they had to fart out all sense of morality, but it's not like that really matters. Morals are for chumps. And you'll know that too, Noir. Especially once you're in my arms. C'mere, I'll give you a taste of what's really good!"

Noir's barrier was pulled towards Blair, and it broke apart as soon as it touched her. And though Noir tried to take the opportunity to slam her fist into her for what she had done, even though she wanted to make sure that she paid everything back in spades...

All that happened was Blair hugging her right before the punch made impact, squeezing the cute black-haired heroine tight. All to trigger one loud and powerful *BRRRAAAAAAAAAAAAAAAAAAAAAAAAAAAPPPPPPP* echoing forth from the heroine's cheeks, as she slowly but surely shrunk in the dark-skinned bitch's arms...

Noir couldn't move. Noir couldn't do a thing. All she could do was feel the sensation leaving her. She could feel everything pouring out through her ass, and she... she loved it. She loved farting everything out. She loved losing her size. She loved it all, especially as she felt something pushing out from her crotch too. She... She..!

He came. With his brand new evil cock. All while he laughed, as he was reduced to the size of a young boy, that now happily cuddled the black-skinned bitch that had pressed all of that shitty femininity and all of that crappy good-hearted shit out of him. He was now Natura Noir, Blair's evil lil' husband, happy to gas up the place and conquer it alongside her. Ehehehehe...

Thus, the world of the Natura Couleur was irreversibly changed. From a world protected by heroes, to a world that fell to their stench thanks to the shitty boy that now led them, as well as his loving and filthy bitch of a bride...

And once the Creator found out about what she had done, Blair would have to explain why she shouldn't be used as a seat for the next few months.
