NIGHT OF THE WITCH

[Chapter 3]

Three days had passed since Shirou subverted Caster, but it might as well have been a year with all that happened.

He wound up summoning a Saber class Servant, who turned out to be the King of Knights in her flesh and blood, unlike the other Heroic Spirits who had already passed. Unfortunately, the relationship between the two Servants wasn't the most cordial. Not only were they rivals in the quest for the Grail, but their characters were diametrically opposite.

A knight and a witch could never get along. Shiro understood that. Caster suggested that Shirou break Saber the same way he had done with her. Naturally Shirou would have none of that. For starters, the knight didn't have any interest in him that way to begin with, and he wouldn't force her or anyone else into something like that against their will.

Fortunately, they had at least managed to come to an accord. Caster didn't actually need the Grail to grant her wish. Her desire was merely to live a second life past the War, and she could get that on her own if she survived. Saber could have the Grail in exchange for her cooperation, to which she reluctantly agreed.

It was clear that Saber didn't trust Caster, but she wasn't really in a position to bargain and was unlikely to find a better deal elsewhere. They had the same Master and he had the final word on things by virtue of him having the Command Seals.

The most amusing part was that Saber knew for certain that Shirou wasn't under the influence of a spell. Had he been, he wouldn't have advocated in Saber's favor against Caster. That was all the proof she needed to know he was acting of his own free will.

Naturally, she wanted to know what Caster meant about breaking Saber the way he had done with the witch. She was most insistent and wouldn't let go of the matter until he explained.

The look of outrage on her face when he explained was quite amusing. Naturally, she didn't believe it at first, but she was convinced the following night when she snooped on them going at it.

The next morning, Saber confronted Caster about her behavior toward Shirou but the latter didn't even try to justify her actions. Witches weren't champions of moral fortitude, after all.

Saber didn't put any blame on Shirou, of course. And she couldn't even dissuade him from partaking in such an unhealthy relationship since it was the foundation of his control over Caster.

But as a result she didn't exactly hold him in high esteem, and their relationship had been strained a bit.

Things remained tense between them until the next night when Berserker came knocking with his Master, one Illyasviel Von Einzbern.

Saber was incredibly strong, and even more so with the support of Caster. They also had the advantage of being in Caster's territory at the temple. But their opponent was the mighty Herakles, perhaps the most renowned hero in all of human mythology. Saber managed to kill him once, but he immediately came back to life and was immune to her attacks from that point on. Caster's Magecraft successfully killed him another couple of times, but eventually he became immune to that as well. He slowly whittled away at Saber and nearly managed to kill her.

She was saved when Shirou pushed her away and got bisected by Berserker in her place.

For whatever reason, that shocked Illyasviel into retreating. He only learned of this the following day, though, when he woke up without a scratch. Apparently, his body had healed spontaneously for reasons unknown.

For the first time, Caster and Saber put aside their many differences and chewed him out for his reckless behavior for the better part of the morning. Caster straight up cried and made him swear never to do something like that again.

He didn't make that promise. His goal was to become a hero and he couldn't do that by letting others die in front of his eyes. Neither Servant was happy with it, but Saber warmed up to him a little bit afterwards.

Another thing he learned, however, was that Illya had called him by name. His identity as a Master was known, therefore it was necessary that he have an escort at all times and that meant that Saber and Caster had to move in with him.

The problem with that was that it would be very difficult getting Taiga to greenlight two women moving into his place.

Therefore, the afternoon after the fight with Berserker, as he came back from school escorted by Saber in casual clothes, Shirou mentally prepared himself to bullshit his way through his sister.

[br]

"This is as far as I'll go," said Saber.

"What do you mean?" he asked. "I thought you were supposed to move in with me?"

Saber shook her head.

"Caster does not wish to give up the temple, and she's correct not to. We both agree that it's too valuable as a place of strategic importance. Therefore anytime one of us is with you, the other will remain there. Besides, it's better if our enemies can't be certain where you are located. She has already fortified the Boundary Field around this place. No one will be able to see inside and even a Servant won't be able to get through immediately. You'll be safe here."

"I'm not worried about that, but I get your point. Still, if Berserker shows up again, you should retreat."

Saber made a displeased face at the notion, but she knew her odds against the half-god.

"I don't think they will be back anytime soon," she replied. "But I will keep your advice in mind."

Shirou nodded. He understood that Saber had her pride, but she also wouldn't risk her life in a fight she couldn't win.

After he was safely past the threshold of the Boundary Field, she went back to the temple. When he arrived home he could feel Caster's presence already inside his house. Leaving the temple unprotected for a little while during the day wasn't that much of an issue. Servants couldn't operate freely during the day and no modern day Mage could hope to subvert Caster's Boundary Fields.

"Welcome home, Shirou;" said Caster as soon as he opened the door.

She was wearing casual clothes, totally different from her usual robes. It made her look less ethereal and much more like a creature of flesh and blood, albeit a breathtakingly beautiful one. The additional layer of makeup she had put on made this effect even more prominent.

Shirou's heart leapt in his chest. Seeing her like this, in his home really made him feel like she was his woman.

"What's wrong?" she asked amusedly, as his mouth hung open like a fish. "Did a cat eat your tongue?"

"Ah! No… it's just… you look so pretty I forgot how to speak for a moment."

She smiled knowingly but she still blushed and looked down at her feet.

"Hm. It sounds to me like you can smooth talk just fine," she replied.

He scratches his head sheepishly.

"Did you have a look around the place?" he asked, changing the subject.

"Of course. I took the liberty of making some modifications to your room. I'm sure you don't mind. Japanese sleeping arrangements aren't precisely to my standard."

"Yeah, sure. It's not a problem," he agreed.

If one heard them talk, they would never imagine that he was the one in charge in their relationship. Shirou had no particular wish to boss her around. Except sexually, of course. He would have to admit he had grown quite fond of being on top, especially since he knew beyond any shadow of a doubt that she loved being on the bottom.

However, they had more or less an equitable relationship the rest of the time.

"Taiga will be here soon," he said. "Did you think of a way to make her accept your presence?"

"Well, it would be as simple as putting a spell on her, but I wasn't sure how you'd take that. So I came up with a different solution. Here, have this."

Shirou took the object from her hand. It was a small pendant with a tiny gem inside of which he could see some kind of intricate pattern

"What's this?"

"A Mystic Code I made. I decided that since you are inept at Magecraft, this would help you."

"I figured that, but what does it do?" he insisted.

"It manifests a perpetual hypnotic field centered on you. As long as you wear it, the people around you will take anything you do as perfectly normal; even if you were to use Magecraft in public, they won't think much about it and soon forget it. They will believe anything you tell them even if it's completely absurd. And if you were to give them an order they would carry it out unquestioningly unless it's something they find completely repugnant and are particularly strong willed."

"What the heck?" he blurted out. "You can make stuff like this?"

"It's fairly trivial," she admitted. "Well, I suppose that for a Mage of this age it would require a lifetime of research and sacrifice to make something even remotely like this in a portable form."

"I can't even begin to imagine the potential for abuse with something like this. I hope you made it so that only I can use it. I don't want to think what would happen if I lost it or it was stolen."

She nodded.

"Keep in mind, it won't be as effective on another Mage, especially if they are already hostile. And it goes without saying that Servants are nearly if not outright immune to it. At the very least, it might help you to go unnoticed if their attention isn't focused specifically on you in battle. Well, it's completely useless against Saber but the other Servants shouldn't boast the same level of Magic Resistance."

Shirou put on the pendant and he felt something like an electric current cover his body. It lasted only a moment and then he felt completely normal.

It wasn't a moment too soon, because he heard the gate open and the entrance door followed right after.

"Hello, Shirou!" Taiga bellowed. "Ah? Who is this person?"

"This is-"

"I'm Shirou's wife," Medea said before Shirou could answer.

"What? Shirou, what is this strange woman talking about?"

"Ahh…" he looked panicked between Medea and Taiga. "That's… that's right. This is Caster and she's my wife."

She blinked and looked at him like he had grown another head.

"Shirou! How could you get married without telling your big sister!" she protested, stomping her foot.

"Wait… is that what you are upset about?" he asked.

He knew what the pendant was supposed to do, but seeing it in action without even a moment of pause on part of the person being influenced by the Mystic Code was jarring.

Then again, this was Taiga. Common sense need not apply.

"Sorry about that. There was just no time," said Medea cheerfully. "It was love at first sight, you see."

Taiga crossed her arms, skeptically. The pendant normalized anything that Shirou did, but that didn't extend to Medea. Taiga had no reason to trust her and while she didn't see anything abnormal with Shirou getting married at his age, she still had reservations about Caster. If he wanted Taiga to buy the story, he would have to corroborate Caster's words.

Besides, it wasn't too far from the truth.

"That's true. I was captivated by her the moment I saw her," he said, looking at Caster. She noticed his gaze and the sincerity of his words and blushed meekly. "There was no way I could let her go. I had to make her mine."

"Something I was more than happy with," Caster smiled.

"Oh," said Taiga. "Well, that's all well and good then."

"It is?" he asked. He had expected acceptance, not outright approval.

"Of course. A man should be decisive in all aspects."

Medea nodded in agreement and Shirou's head spun at how surreal it all was.

"Anyway, Shirou, when is dinner going to be ready?" Taiga asked

"Uhh… it's going to take a little while. Why don't you take a seat in the living room and relax while I cook?"

"Alright, but I want snacks in the meantime," she said, walking past him.

"I'll help you cook, Shirou," said Caster with a smile. "It's the least a good wife can do."

[br]

In spite of the addition of his recently acquired wife, dinner was a surprisingly simple affair. Taiga did most of the conversing which was just fine. She didn't inquire too hard into the details of how Shirou met Caster and when the alleged wedding had taken place. She had already accepted their story to such a degree that she wasn't even curious about it.

"It's almost scary how she is just… taking everything at face value," Shirou whispered to Caster while Taiga was distracted watching the news on TV.

"This much is nothing," she replied. "She won't find anything you do abnormal in the least. Do you want to try it out?"

"I… guess. What do you have in mind?"

"Give me your hand," she said and he complied.

She took it and placed it on her breast with a sigh.

"Hnn…" she moaned.

Shirou's eyes immediately went to Taiga who briefly glanced at them before going back to look at the news.

"See?" said Caster. "Nothing you do will make her think it's wrong. In fact, as long as you clearly accept it, she's not going to react to anything I do to you either.

She put a hand on his crotch and started rubbing it.

Again he looked at Taiga, but she didn't pay them any attention. Not even when Caster unzipped his trousers and pulled out his cock.

"What do you think you are doing?" he asked under his breath.

"Nothing you don't want," she replied smugly.

Indeed, while Shirou had a strong moral compass and wouldn't allow for innocent people to be hurt, he wasn't nearly as inflexible when it came to naughty things. She had breached through those paper thin defenses on the very first night and the mark she had left on his young, impressionable mind made it very difficult for him to reject her advances.

While Shirou was unquestionably the one on top, their relationship wasn't entirely one sided. Caster had plenty of wiggle room to push his boundaries.

She stroked his cock to full erection. His massive shaft, too big for even a full grown man, stood so tall that it reached far above the edge of the table in full sight of Taiga, who turned to look at it with wide eyes.

"Ahh… isn't she supposed to not notice?" he asked Caster.

"No, she just doesn't find anything wrong with it. But just because it's not out of place, it doesn't mean it's not interesting."

"This is so wrong," he said.

"You don't believe that," she teased before sucking on his earlobe.

She was right. If he was really against it, the Command Seal would have stopped her, and even Taiga would have protested.

Shirou didn't say anything, but he started breathing heavily while she jerked him off.

"You have such a magnificent cock," she purred in his ear. "It's so big and manly."

"R-Really?" he stuttered.

"Absolutely. It makes me wet just by touching it with my hands. Taiga, don't you think Shirou's cock is great?"

"Ah?" Taiga jumped at being called on the spot. The hypnotic field made her accept what happened as not wrong, but it didn't provide her with a framework to respond to something she had no experience with. Her face was flushed red, and her eyes were glued onto Shirou's member.

"I… I guess?" she replied. "It's my first time seeing a real one. I was… under the impression that they were much smaller than that."

"Oh, they are. Shirou's is almost twice as big as the average man's. And it's going to grow even bigger as he matures further. It just goes to show how exceptional he truly is."

"But it's so big. I mean… does it even fit… you know… inside?"

"Hmm… it was a bit uncomfortable at the start, but once he was done reshaping my pussy to accommodate its size it felt really great."

"Is… is that so?" Taiga asked, fidgeting. Her face was an intense shade of red, and her chest was heaving more than normal.

"What… are you doing?" Shirou asked.

"Just having a conversation with my sister-in-law," Caster replied.

Just like before, Shirou might feel embarrassed but wasn't truly opposed to what was happening. His discomfort didn't exceed the pleasure he was feeling, and his cock was throbbing madly in her grasp.

"It looks like Shirou doesn't know how to take a compliment," she said to Taiga.

"He's always been like that," Taiga said with a nod. "Like I told you many times, Shirou, when someone gives you a compliment you are supposed to say thank you."

"She's right, Shirou. When someone praises you, you should be grateful and proud. How about we practice a little bit, hmm? Taiga… why don't you tell him what you think of his cock?"

"Ah… uhm… I… You have… a really nice cock Shirou. It's… it's very big and strong."

"Khh…" he groaned.

His face was on fire but his cock had hardened to a heretofore unknown degree. While the scars of his past trauma made him question the worth of his continued existence and deprived him of any sense of personal accomplishment or pride, at his core he was still a human being.

He was still a man.

Like any other male, he wasn't immune to the approval of the opposite gender.

"Looks like that wasn't enough, Taiga. Try to make it more than just perfunctory. Put your heart in it."

"There's… no need… I… Khh… get it."

It was obvious that his heart wasn't in those words.

Taiga's eyes were almost spinning in their sockets and couldn't make sense of why she was feeling so embarrassed. There was nothing wrong with the entire situation but she was uncomfortable doing something she had never done. However, it was for Shirou's own good.

She took a deep breath, and looked Shirou squarely in the eyes.

"Shirou… you have a great cock. Caster is very lucky to be your wife. You will make her very happy with it."

The hypnotic field might have removed her common sense, but it didn't alter her mind in any other way. Taiga wasn't one to lie or give praise needlessly. Those were her own thoughts spoken sincerely.

Between that, and Medea jerking him off, Shirou couldn't hold back any more.

"Th… Thank you. Argh!"

He climaxed, but before he could make a mess of things, Medea grabbed her empty glass from the table and directed his load into it. Shirou's ejaculation was so intense that he managed to fill it entirely. A drop of it even slipped out and made its way down the outer part. It never managed to fall, as Medea brought it to her mouth and licked it off, before placing the edge on her lips and slowly swallowed it down.

Both Shirou and Taiga were wide eyed as they watched it unfold. If possible, Shirou's dick became even harder.

"That's so lewd, Caster!" Taiga exclaimed, extremely red faced.

"Hm? Why would it be lewd? Am I supposed to let my husband's seed go to waste?"

"Ah… Well… I guess not… but still!"

"No, I understand. As you said, you've never seen a real cock before, therefore your sexual experience is zero. Anything beyond holding hands would seem lewd to you. I assure you, drinking your partner's semen is perfectly normal."

"Is it really?" Taiga asked.

"Trust me. You are merely speaking out of inexperience but that can be easily rectified. Shirou and I can show you how two lovers act with each other. Would you like to see that?

"We… well, if it doesn't bother you," she replied.

If Shirou's eyes could bulge any more, they would have popped right out of his skull. He couldn't believe what he was hearing. Taiga wanted to see him fuck Medea. Of course the inhibition of morality had been removed, but he never dreamed that his surrogate sister could harbor such curiosity at all.

Then again, he never considered Taiga to be a woman at all. He knew she was a strange person, but to him she had always just been Fuji-nee.

"Shirou, you don't mind fucking me right here in front of her, do you?" Medea asked.

Had she asked that question no more than ten minutes before, he would have replied no way in hell.

But in that small frame of time, she had worked up his arousal to the point that ejaculating just once wasn't enough to restore his common sense.

She wanted it, he wanted it, and Taiga wanted to watch. Who was he to say no?

However, he didn't reply verbally. Instead, he got on his feet with his cock still out, grabbed Caster's head and forced her to bend over the table.

"Ah! So forceful!" she cried.

"You are the one who said she likes being bullied into submission," he told her. "Are you taking those words back now?"

Before she could answer that question, he pulled up her skirt and revealed her ass. She hadn't been wearing anything underneath. Her round butt and her wet pussy were fully exposed.

"Does it look like I regret it?" she asked, wiggling her bare butt at him.

Shirou was flabbergasted.

"You were planning this from the start, weren't you?"

"Hmm? So what if I was? What are you going to do about it exactly? Are you going to punish me like you did that night?"

And there was the crux of the matter. They had been intimate daily since the night he bound her with a Command Seal. However, he never took her as forcefully as that time. It wasn't Shirou's character to bully others, even if they wanted him to.

So she had to work him up to it by pushing the limits of what he found acceptable.

And here they were, now. He wasn't quite angry but his emotions were in turmoil and his arousal was at its peak.

"That's right, I'm going to punish you."

Smack!

His hand flew and met the pale skin of her buttocks.

"Kya!" she squealed.

A Servant's body couldn't receive damage from a mundane attack, but that didn't mean they couldn't experience physical pain. The impact from Shirou's hand set her skin on fire. It was swiftly followed by another slap and then another.

"Hmm!"

Medea bit her lip, moaning through the pain.

Since when did she have the disposition of a masochist? She had been thinking about it since that night. Did she grow accustomed to the abuse in her youth from the man who took everything from her? Or maybe she was just like that from the start and she has been merely a suitable pawn in more than one way.

But in all likelihood it was much simpler than that. She was just a naughty woman who liked perverted things.

That was the answer she embraced because it was the easiest to accept. It was nothing more than cowardly escapism, but so what? She wasn't a proper hero. She was a Witch, not a paragon of any kind of virtue. She did only what she wanted with no regards to anyone else.

With each slap she received, her pussy got wetter and wetter.

She was panting loudly now, her face mere inches away from Taiga's, whose mouth was similarly hanging open in shock.

Really, if he continued to slap her, Caster would have wound up leaning against the other woman, but before that happened Shirou grabbed her by the hair and forced her back, just as he lined his cock to the entrance of her pussy.

He slid the tip inside her folds and held it there without going further, just rocking his hips around.

"Ahhh… come on…" she gasped.

"No way," he replied through gritted teeth. "This is supposed to be a punishment. You don't get what you want."

"P…Please… I need it."

"First, you have to apologize," he insisted.

"Fuhh… I'm sorry, so please…"

"Do you even know what you are apologizing about?" he asked, pulling back a little bit.

"Ahh… for… for misleading you… I'm sorry- Ekk!"

Shirou smacked her ass again.

"Wrong. Do you really think I'm upset by this?"

"Auhh… for… for getting Taiga involved in it? Ekk!"

"Wrong again. It doesn't look like she's bothered by any of it, right Fuji-nee?"

Taiga shook her head weakly. She was wide eyed and red faced, but she wasn't looking away.

What else was it then? What else was she supposed to apologize for? Why was he bullying her like this?

"Ah…"

He was bullying her because she wanted to be bullied. Everything came as the result of her own desire, therefore the thing she ought to apologize for was that.

"I'm sorry! I'm sorry for being such a lewd and indecent woman. I'm sooOHHH!"

He slammed his cock deep inside of her in a single motion, stretching her pussy wide with its impossible girth and hitting the entrance of her womb with the tip.

Her body shook around his cock and her eyes went crossed. It was more than just the physical sensation of his tyrannical cock claiming dominance over her body.

"I forgive you," he groaned in her ear.

The words he spoke were even better than a declaration of love. She had once again betrayed him, because that was her nature. And yet he forgave her.

She had been craving that absolution just as much as she did true affection. Perhaps even more. Maybe that was what she really sought after Jason abandoned her. Not revenge, but forgiveness.

This was the day when she found a new way to live. Now that she had met this long sought-after person, he could punish and forgive her in a perpetual cycle.

"Ohh… Master. My Master. Take this body of mine and use it to your heart's content. Let me be your plaything for life."

"Is that… really what you want?" he asked.

The Command Seal meant she couldn't outright deceive him, but that didn't mean she couldn't be swept by emotions and make a bad decision.

But Medea turned to look at him from behind her shoulder.

"Yes. I don't want anything more than that."

Her eyes were clouded with lust but they were also flooded with a level of happiness that reminded Shirou of Kiritsugu when he saved him from the burning city.

He wouldn't mistake that for anything else. If this was what Caster's happiness looked like, he would do everything he could to grant it to her.

Because that was what heroes did.

Perhaps, if his own thoughts weren't clouded by his own lust and desire, he would have felt that it was wrong for her to live that way, especially with him. But his judgment was impaired and he came to the conclusion that he simply had to fulfill her wish to the best of his ability.

But it wasn't as straightforward a task as it appeared. She didn't just want someone to have their way with her whenever they were in the mood, but someone to torment and bully her every single day. She had chosen him because he had shown that he could be harsh and forceful with her.

So that's what he had to be.

"Swear it then, on your true name. Let me hear it with your own voice," he growled in his ear.

Medea's pussy clenched when she heard his demand. There were no Command Seals involved this time, and it was no mere game either. He was telling her, in no uncertain terms, to put her money where her mouth was.

Did she truly want that?

'Yes. Gods, yes. I want this with all my heart.'

All that was left then was to follow through with it.

She reached out along her stomach, pushing against the point where she felt her abdomen bulge out from the intruding mass of Shirou's dick.

"I… I Medea of Colchis hereby swear that from now henceforth, I will be Emiya Shirou's faithful slave. I will devote myself to be his exclusive plaything, his personal fuck-toy, his custom cock-sleeve and his filthy cumdump."

A faint glow shone where her fingers touched her lower abdomen, and Shirou felt some kind of heat spread through her loins.

"Let this seal be the proof of my oath. Let my status be known to anyone who sees it."

The light intensified, and a mark shaped like a stylized uterus with a heart shape in place of the womb appeared on her skin.

This was more than just an oath. This was a self-imposed geas with an hypnotic effect not unlike the pendant she gave him. Even Shirou felt its absolute certainty that Medea belonged to him. His budding affection for her didn't diminish, but the effect of the spell changed the way he saw her. in his eyes, she was now all of those things she had just listed.

In one smooth motion she had stripped him of any hesitation about using her as a sexual object. Even the knowledge that it was the effect of a spell didn't do anything to alter his emotions.

"Oh my God!" Gasped Taiga. "So this is the kind of person you are!"

"Yes, that's who she is," Shirou agreed, feeling his cock twitch. "So there is nothing else to do but treat her accordingly, right, Fuji-nee?"

Under the effect of two distinct hypnotic fields working in conjunction Taiga's common sense was completely blown off its hinges.

"I would be very disappointed with you if you didn't," she replied. "You better put that huge cock of yours to good use and fuck her the way she is meant to be fucked."

"Oh I will," he promised. "Just sit there and watch how it's done."

Without taking his cock out of her, Shirou spun her around so that she was laying with her back on the table. He grabbed the collar of her shirt and pulled, ripping it open and letting her breasts bounce free. Of course she hadn't been wearing a bra either.

He slammed his cock deep into her a couple of times, before she could wrap her legs around his back.

"Yes! Yes! Fuck me, Shirou! Fuck me hard! Ahhnn!"

With her legs preventing him from pulling back too much, Shirou frantically thrusted his pelvis within the space he had available. Each thrust made her stomach bulge a little bit and the mark on her stomach seemed to throb every time he hit her cervix.

He rammed his dick into her like a machine gun, making her howl like a wild animal. All the while Taiga watched with an enraptured expression.

"I'm going to cum," he warned her.

"Ahhh! W-Wait! The moment your seed hits my womb, the mark will become permanent. If you cum inside of me now, I'll be your fuck-pet for the rest of my days with no way out."

He realized then that the spell wasn't affecting only him, but Caster as well. She had basically hypnotized herself into this role.

So why was she asking him to stop now? Well, because she was a witch, of course. She was transferring all the responsibility of finalizing the deal on him, even though it was her who had twisted his mind.

But then again, everything came from his decision to save her even though he knew from the start that she was a bad deal. He kept her from being as evil as she wanted but in exchange he could no longer be as good as he would have been.

To redeem a piece of her soul he had to lose part of his own. The law of equivalent exchange bound even the greatest of Magi.

There was no turning back. The trade had already been made. This ritual was only a formality. The question she was truly asking was another.

'Will you take responsibility?'

She didn't know that he was a person bound to his actions even before she met him. Thus her unspoken question had only one possible answer.

He slammed his cock one final time inside of her and with a grunt he released the biggest load of his young life into her innermost place.

Medea's eyes widened, feeling the heat of his seed flood her womb. The seal on her abdomen became burned into her skin.

Shirou's first Command Seal had already traced a path to her Spirit Origin that was still open because the order was still in effect. This new spell followed after it and joined it.

The two separate imperatives found extreme synergy in each other and reinforced one another way beyond anything even Caster could imagine.

Her Spirit Origin started to shift. The change to her character was no longer a compulsion held by the power of the Command Seal, but a true alteration of her very soul.

She climaxed, harder than she ever had, and in the throes of her orgasm she felt the change take place in her brain.

Servants might have been made of spiritual particles but the function of their organs was the same as regular humans. In that moment, several of her synapses burned away and new ones took their place. Her priorities shifted and so did her needs and wants.

It was an irreversible change that even Rule Breaker couldn't undo.

She was no longer the Witch of Betrayal after all. She had become Emiya Shirou's Witch of Lewdness. To be used by him was her purpose. His pleasure was her only wish.

She had changed herself in a way worse than the Gods of Olympus had ever done to her, and in a completely permanent manner on top of it. There was no regret though, simply because she couldn't experience it anymore over this matter.

The only thing that made it perfectly fine, was that it had been her choice. As stupid as it sounded, she had done it because she wanted it.

Her loyalty to her Master had become unquestionable. She would never even dream of defying him for real, and she would rather die than betray him. But why would someone who had already been made into someone else's lovesick puppet in the past turn herself back into one of her own volition?

The unfortunate answer was because, as tragic as that was, that time of her life was the happiest she had ever been. The pain that turned her into a loathsome Witch didn't come from the heinous crimes she had committed while brainwashed.

It was the result of that veil being taken off her once her role was complete.

The reason why she capitulated to Shirou's forceful handling of her deception was because, deep in her heart, she secretly wanted to go back to being a person who existed solely for the convenience of another.

Nobody could take that away from her now. Not even the Gods.

So while Shirou's cum drowned her womb, reshaping her soul, mind and heart, the only emotion she felt through her own brain shattering orgasm was a feeling of completeness and supreme happiness.

"Masteeeer! I love youuuuu!" she howled as her eyes rolled in the back of her head.

At that moment, Shirou leaned forward and kissed her, sneaking his tongue into her mouth.

She wrapped her arms around him and pulled him further into the kiss, losing herself to this new feeling of being completely owned by someone else.

As their tongues danced together, Shirou's ejaculation came to an end, but true to his youth his cock was still hard as rock inside of her body.

He broke off the kiss and looked at her with both affection and lust, which was more than her first husband gave her through their entire sham of a marriage.

For the next several hours, Shirou ravaged her body on the living room table, in every conceivable position, all under the aroused gaze of Taiga.

Afterwards, completely exhausted and satisfied, he laid upon Medea's equally limp body. Both were breathing heavily and couldn't so much as raise a finger.

"I think… I think I have learned a lot today," Taiga said.

"Yeah… well… don't think too hard about it," he told her. "In fact, don't think about it at all."

She nodded.

"That's probably for the best. Well, I think I should go now. I'll see you tomorrow for breakfast, Shirou."

She got up and walked out like nothing had happened. And yet, so many things had changed drastically.

However, he could deal with it later. At that moment, the only thing he wanted was to sleep.

He closed his eyes and fell into a deep slumber atop his Servant.

His wife.

His slave.

His Witch.
