[Corruption, Bondage, Mind Break, Latex]



"Ah, Jeanne. On time as always. I'm glad to see that you're still following orders."



The soft smile on the young man, Fujimaru Ritsuka, contrasted the darkness of the room around him. This was a quirk that his Servants had grown quite familiar with ever since he summoned them into his service. He preferred to slink around in the dark whenever possible, even when he was doing his best to save the world from the temporal anomalies that they were suffering from. And despite how much that might worry an ordinary human, they quickly grew used to it because he didn't really show any signs of malicious intent.



"I wouldn't want to disappoint you, Master." One of his most important Servants, Jeanne D'Arc, put her hand against her chest as she bowed slightly. She had served by his side ever since they delved into France to save the world from her fake Alter self, and thus she had started to see all of his habits as just something that made him who he was. Even if she still didn't quite like the dark rooms littered around Chaldea due to his habits. "Though, if I may ask... You wanted me to hurry here. What did you need me for?"



Ritsuka smiled from ear to ear, his smile seeming almost unnatural with how wide it was, before he snapped his finger to shine a single light down on something behind him. Something large and thick, painted grey with intricate runic inscriptions. But despite how much it had been prepared, it was easy to tell what it actually was.



It was a large wooden cross. Not unlike the one that Christ had been crucified upon. Just looking at it was enough to send shivers down Jeanne's spine. What would her Master need a cross for, much less one as decorated as this one?



"Well, it's just a little something I've been wanting to try out. Ever since Chaldea hired me, I really haven't had the time to practice my hobby. So I thought that you might be able to help me out, Jeanne. You wouldn't say no, right?" Ritsuka chimed, holding up his hand as one of the segments of his Command Seal started to fade away.



Before Jeanne had the chance to raise her voice and tell him to stop what he was doing, her body fell limp and her consciousness left the building, the blonde Ruler quietly collapsing onto the ground as if all of her muscles had just locked up and failed to carry her weight...



Ritsuka chuckled as he looked at the beautiful blonde laying on his floor. "You really are beautiful when you're incapacitated, Jeanne..." The young man sighed sweetly as he carefully undressed her, removing every little article of clothing covering her body. She didn't need all of that when she was bound to the cross. She needed something that would make the experience all the more unforgettable.



He had of course prepared everything important beforehand. Coercing Da Vinci to help him materialize the necessary tools and crafting what he wanted to the exact specifications. She'd be next in line for what he had planned, but he needed to make sure that Jeanne enjoyed herself first and foremost. After all, she had been helping so much. It was only fair.



The Master grabbed the first and most important garment off one of his desks, a long and tight looking black latex catsuit. Slowly but surely, he forced the young lady to slip into it. Pulling her feet and legs into the catsuit as he made sure that it fit as tightly as it should. Which was of course a bit too tight for somebody like her. But that was what he had asked for. It wouldn't be nearly as fun if she felt comfortable while she was wearing it.



As he managed to fit her legs into it, he couldn't help but lick his lips a little as the latex dug into her pussy. He could see how it perfectly outlined those lower lips, and he could only imagine the kind of cries that she would make if she tried to get it off. To have that tight black fabric digging into her, paralyzing her with pleasure. It was something that he loved to listen to...



Ritsuka managed to fit her into the rest of the suit with about as much difficulty as the legs, though he took particular note of how difficult it was to pull the last bit of the suit over her chest. Ah, to have breasts that big. The tightness would make them a tiny bit smaller from how much it pressed up against her... But that would just add to that delight he'd hear from her lips, now wouldn't it?



Before he made sure that the catsuit had been fully attached, he added one more thing to complete the base look she'd adopt. Namely a long pair of latex boots that not only would stick nicely to her completely compressed legs, but it would also make it incredibly difficult for her to walk. Not just because of the obnoxiously large heels she'd have to balance on, but due to how they were even tighter than the latex was... And that she now had to fit into them with the latex covering her. Something that would bring more music to his ears in due time.



After that, he secured the catsuit to the point where everything but her head had been covered. Then it was time to add one more thing before he'd hoist her onto the cross. A corset. Because it wasn't just enough for her to be tightly pressed down by the suit itself. She couldn't go without pain for even a moment, otherwise his enjoyment would drastically sour.



He wrapped the corset around her torso and made sure that it had been properly adjusted to put as much pressure on her body as possible, before tugging and tying every little piece of string as tightly as possible so that it was on the verge of snapping off yet remained as tight as it possibly could. The finest point of balance between breaking free and total agony. That little chance to break free that she wouldn't reach would only serve to break her quicker once she started struggling.



Finally, Ritsuka lifted his unconscious Servant into the air and pressed her up against the cross. Using his hands to guide her arms into the proper stretched out position, he activated the inscriptions on the cross, causing it to form several tight looking restraints that would pin her against the cross... But it wouldn't exactly support her weight. She would be forced to deal with gravity working its magic on her body, serving as yet another piece of pressure that she would endure. Another source of pain to make the pleasure pouring through her all the more enticing...



Taking a few steps back, he had to admire his handiwork. He had managed to squeeze somebody as noblehearted, somebody as pure as Jeanne D'Arc, the Saint of Orleans... Into nothing more than a dehumanizing latex catsuit and strapped her to the cross as if she had once again betrayed her beliefs and her faith. There was just something incredibly arousing about that sight, but he needed something more than that. And so he listened carefully.



"H-haah... H-Hurts..."



Even though she was still unconscious, the pain was starting to spread through her. Then again considering how many parts of her body were now being pressured due to either the clothes she wore or the predicament she was stuck in, it would be amazing if she wasn't experiencing any pain. But no. Here came the slightly pleasure-filled cries of being stuck within something as agonizing as pure latex...



"H-hurts..!" Jeanne cried out as her eyes shot open, the pain being too much for her to endure. And in that moment, when she finally regained consciousness... All of that pain intensified by a few notches, since she was fully aware of what was happening to her. "A-AAAAHH!" She screamed from the depths of her heart, whether it was due to the way that the latex dug into her limbs and her most private areas, the way that her lungs were being compromised by the tightness of the corset, or the fact that her arms were trying to tear themselves away from her body thanks to being crucified.



Ritsuka giggled as he listened to his Servant's wonderful cries of pain. Ahhh. Yes, this was exactly what he wanted to hear. There was just something wonderful about hearing a woman like her crying out, to see her in delightful desperation. He almost lamented the fact that he couldn't capture their female enemies, especially the Alter version of the Saint, and use them for whatever he wanted. But seeing her go through the same kind of treatment that he had planned for her was more than good enough for him.



Jeanne struggled against her binds. But she found that she could barely do anything. Primarily because her body just wouldn't respond. The bloodflow to her body had been incapacitated to such a fine degree that yes, she wouldn't die due to atrophy or anything of the sort... But the flow would be inadequate. She couldn't move. All that she could do was breathe, and even that was painful due to the corset. And to make matters worse, if she tried to breathe... Then the suit would dig into her privates or her breasts, pressing down on her intimate areas.



"W-Why... M-Master..?" She whimpered, her body seizing up as her eyes nearly rolled into the back of her head as she struggled to get a little bit of air down into her lungs. "C-Can't... B-Breathe... H-Hurts..." She muttered, trying to conserve as much of that air as her vision started to blur just looking down at the young man that she had trusted with her life. What had she done to deserve all this? Was he... Had he played her and everyone else for fools, wanting nothing more than to unravel human history for his own entertainment? What was his end goal in all of this? She truly did not understand.



Ritsuka trembled a bit as he heard that wonderful lack of air leaving the girl's lips. He wanted more. Much more in that vein. "I told you. I wanted to practice my hobby. And a beautiful girl like you has always been perfect for it." He explained, stepping ever closer as he started to let one of his fingers carefully and slowly dance along her latex-trapped body...



That little bit of pressure was enough to send sparks of pain pouring through the girl, forcing her to scream despite the lack of air in her lungs. And she'd have to sharply inhale to try and get a little bit of air back in, only serving to make her feel more pain and scream once more, the endless cycle taking effect the longer he slid that finger along her body.



"So cute." Ritsuka giggled as he listened to the wonderful cries she let loose. All while his finger idly circled her stomach for a few seconds, drawing out it all. Every single little bit of pain, every single moment of despair settling into her soul. But there was something below that he still wanted to check out. So he carefully let his fingers take the trek towards her crotch, tapdancing along her crotch until...



Jeanne's eyes widened in the midst of her painful onslaught. Because she felt a sensation that was even worse than the pain. She was wet. Not just a little bit wet. She was thoroughly soaked down below. How was that possible? She wasn't... She wasn't into that kind of stuff. And yet the evidence was right there. The puddle slowly forming at the base of the cross thanks to the juices pouring down her thighs... She was terribly, impossibly aroused. And she couldn't do anything to argue against it. Because it would just make her make an even bigger mess...



Ritsuka laughed as he carefully licked his fingers clean, those tainted juices tasting sinfully sweet compared to anything he had ever tasted before. He would love to savour the taste, but then he'd have to let her endure this for longer without getting any further. And he was a busy young man. He had much to still plan for.



"You're very good at this, Jeanne. I'm very glad." He said as he idly walked towards a closet in the back of his room. A closet that eminated a foul stench. A foul aura. The very source of darkness that had been coating the room before she entered, that now started to consume the light that was shining down on the crucified girl and coating her in a nice red light. "Which is why I have to give you one little present. One that will make you all the more beautiful. All the more alluring to somebody like me."



Jeanne couldn't see what he was talking about. Because she couldn't turn around while she was stuck on the cross. All that she could do was feel the sensation of pure evil crawl over her. Sending more spikes of pain through her system, her body growing more and more used to it all. Which just served to make her slowly but surely addicted to the pleasure that came with it. She hated it. But expressing her hate would lead to more pain...



But once she laid her eyes on the source of that evil, she couldn't stop herself from sharply inhaling and flinching. She couldn't believe her eyes as she saw the mask in her Master's hands. That black, red-striped mask that emphasized her eyes. What... What was this mask? Why did it feel so evil? And why was it calling out to her? She wasn't... She wasn't meant for it. She was a holy maiden. In fact, if she wore it... The sheer amount of evil energy inside it could probably break her to the point where her Saint Graph would be irrevocably changed. What would happen to the version of her back in the throne if she was forced to wear this mask? What would... What would it force her to do, should she fall to it..?



"M-Master. Please. I-If you... If you still have good in your heart..." Jeanne did her best to fight back against the pain. Just this once. To try and appeal to the man that she knew her Master as. "You... You'll put that mask down and destroy it. It will destroy me if you put it on my face..." She tried. She had the tightest feeling in her chest. Knowing that it could possibly fail. But she had to try and appeal to him.



Ritsuka just smiled in the face of her begging. "Good? Jeanne, there's no such thing as Good." He said with his smile twisting even further than it already had, before he pressed the mask against her face and watched as it practically glued itself stuck using its evil energies. It was a perfect match for somebody like her, and he couldn't wait for it to show results.



Already, the evil energies poured through the latex. Pouring through her body, amplifying the pain that she was already feeling. While worming into her head, poking and prodding at her independent thoughts and her dependence on the one above. And all she could do was silently scream inside her mind, because the mask was shaped in such a way that her mouth was forced open as if it was forced to suck on a ball gag.



Drool poured out of the holes in the mouth of the mask, as Jeanne's pleasure intensified the more she was being subjected to this pain. All while the evil mask whispered into her ears. Slowly but surely putting a pick to her belief in god. In her belief in herself. In her belief in the good in man.



Because it was that very same belief that had landed her in this situation. Because she trusted another person, because she laid herself bare in front of her Master... She was now crucified upon the cross for her faith. In fact, it was her utter faith in the goodness of the human heart that had landed her in this latex prison. It was that vain attempt to think that people wouldn't betray her like they had in life... It was what had led her to this fate.



Her expression at this point was completely sealed away. But Ritsuka could tell that she was suffering. She was trembling even more than before. And there was a little something pouring out from her mask that wasn't as salty as her saliva. It was her tears. Oh, how utterly delightful.



It was time to reward her for accepting her role in all of this. He reached for a a few toys, most importantly something that he could wrap around her, and giggled. A set of egg vibrators would do much to her, especially these that blended into her suit with how dark they were.



With a little bit of magic, it was easy to attach them. Sticking them right up against her most intimate areas, that had started to push out against the suit. Her nipples, her clit, all of them were surrounded by vibrators on all sides. And once they started vibrating, they wouldn't stop until they ran out of power.



Jeanne drooled more and more as she was assaulted by that pleasure. The pleasure was intensifying in tune with the curse and the evil inside the mask. It was horrible. It was awful that she was growing more and more accustomed to it. And it was awful that it kept prodding at her. Telling her that this was what she was always meant for. Just like how in life they kept abusing her.



It wasn't what she was meant for. She was... She was a holy woman. But her faith had been leading her down this path further and further. The voice inside the mask was right. It was telling nothing but the truth. So why did she still resist? Because of some vain hope? The same vain hope that had led her here in the first place? She knew better than to trust in the same awful hope, as it would just lead her here again...



Jeanne... Slowly came to accept the mask's words. The mask was right. And the way that it made itself apparent was by making her eyes shine against the mask. Two bright red irises piercing through the black, as the evil seeped deeper and deeper into her. It wouldn't be long before she'd be just as twisted as the mask itself.



But at the same time, Ritsuka knew that if he interrupted ever too early... Then the final product wouldn't be nearly as fun. He had to give her time to truly stew in her own failures. So even though he was having fun slowly pressing his hands against her hips or squeezing into her breasts as she was being stimulated by the vibrating eggs...



He had to leave her be. This was the most crucial step. The part where he had to abstrain, so she ended up taking on the perfect form. And though he could hear the subtlest of cries coming out of her mask, it was not enough to draw him back in.



Jeanne would be left alone for a long time... Maybe until he completely forgot about her. Just so that she could be truly corroded by the evil mask...



---



It had been a good... Oh goodness, how long had it been? A month? It had definitely been a long time since he last visited his room, which he had sealed off with a bit of magic and used his Command Seals to ensure that none of his other Servants would dare venture inside and ruin his plans before they came to fruition. But the time has come. The seeds that he had planted should be ripe for the harvest.



The door opened, and the evil miasma started to sweep out into the halls of Chaldea. He would have to deal with that and make sure that it was all kept hidden. Otherwise the others would act as spoilsports. But he could worry about that later. For now, the prize was waiting for him.



Once the tiniest ray of light managed to pierce through the darkness, he saw the Ruler still pinned against the cross. Even though so much time had passed, she was still being an obedient girl who refused to get out of her designated spot. How adorable. If he was that kind of Master, he would've given her a gold star.



But there was one little detail that seemed different compared to when he had let her be. And that was the design that had leaked off the mask and onto the rest of her latex prison. Lines that now emphasized where she was most sensitive. Certain spots that were best to touch. Whether it was her still-vibrating nipples or clit, her hips, her buttocks... Every little spot that a girl like her might feel an excess amount of pleasure from was marked by the red lines running along her body.



And on her face... The mask was gone. It had probably returned to the closet, if he had to guess. But the pattern remained. Her face had turned completely black, just like the latex she wore. And she smiled from ear to ear, grinning as her red irises shined against the black of her eyes. She was delighted to see her Master. the man that had betrayed her.



Ritsuka held up his hand, and his Command Seals burned away for the day as she was let free, and her body rushed full of energy. "How do you feel, Jeanne?" He asked, as he stepped so close to her that she could've probably inflicted mortal harm upon him if she felt like it. The evil inside her heart would no doubt push her to do it, considering what he had done to her.



All she did to answer him was wrap her arms around him, trembling from how tight it still was, before pressing her lips against his. She then pulled back and leaned across his shoulder, whispering a few dangerous words into his ear, showing how much she had been corroded and putting a pin in the fate of every other Servant she had worked with.



"Help me, Master. Help me betray them all, and show them what they deserve for leaving me all alone."
