NIGHT OF THE WITCH

[Chapter 2]

Several days later

That afternoon, after school, Shirou was making his way to the temple, just like he had been ever since his first meeting with Caster. A lot of stuff had transpired since then. The most striking was the so-called Holy Grail War. A conflict between seven spirits like Caster, summoned from the legends of heroes across time by an equal number of mages to command them.

This war happened every sixty years, but for unknown reasons only seven had passed since the last, and the fire that orphaned Shirou was most likely a result of that. Needless to say, that revelation angered him to no end. He didn't want a repeat of that incident. He was going to be the hero and prevent it from happening.

The second thing was that he was doing Magecraft wrong. After watching him once, Caster explained that instead of using his actual Circuits he was making a new one each time. She taught him how to do it right and now things like Reinforcement, Projection and Structural Analysis were almost trivially easy. Unfortunately, Caster couldn't teach him anything else that was of practical use. Their styles of Magecraft were fundamentally different.

But she taught him a lot about theory. In particular about the underlying mechanism of the Grail War. Shirou wasn't technically Caster's Master. He didn't have the Command Seals that marked him as one who had been chosen by the Grail. He couldn't order her to do anything.

Normally that wouldn't bother him, but strange things were happening around the city. People were fainting and were hospitalized. The most frail died. There wasn't any specific cause listed, but people were whispering about it. Shirou was a trash-tier Magus on all accounts, but that sounded very much like the result of mana depletion.

On a city-wide scale, it had to be the work of a powerful Magus. Now, Servants were divided into seven classes according to their ability. Saber, Archer, Lancer, Rider, Berserker, Assassin and Caster. As the moniker implied, Caster was a Magus. Likely the most powerful Magus in the world at present.

Shirou didn't forget the first impression he had of her. That of a witch. He had little doubt that the mysterious deaths were her doing. He trusted his guts. However, he had no way of asking her for confirmation. She had made things quite clear when he told her he wanted to take part in the War. He wasn't even an ant to the Servants, and even the other Masters would make short work of him. If he asked questions she didn't like, she could easily warp his mind and make him compliant.

Shirou and Caster had intercourse every single night. She was as passionate in bed as she was detached outside of it. She saw him as nothing more than a boytoy and an anchor, as well as a Mana Battery. In her opinion he couldn't harm her in any way. And she was right on the money… until this day.

That morning a very distinctive sign appeared on his hand. A set of Command Seal as Caster described it. In the end, the Grail had chosen him as a Master. He immediately put her lessons to good use and closed the circuits to his arm, making the seal fade from sight.

She didn't come looking for him, so he was confident she hadn't realized yet. He had to act before she did. He thought long and hard about how and when to use it. When she explained the workings of a Tantric Ritual, after their first night together, she said something about magical defenses being at their lowest during a climax. If he used a Command Seal on her at that moment, it would take hold much better than normal. At least he hoped it would, otherwise he was screwed.

A normal person would have thought twice about crossing a Servant, but Shirou cared more for others than himself, so he was more than willing to take a chance.

He got to the temple fairly early. The monks and Issei greeted him as usual. No one ever mentioned the new person living on the premises. It was like she didn't exist, even though she moved about in physical form however she pleased. They were all under her spell. Shirou considered himself lucky not to have suffered the same fate.

He felt it was because she actually liked him. It made him feel a bit bad about what he was going to do, but she left him no choice. One person's hero is another person's calamity.

He went about his business at the temple as usual, and when night came he called Taiga to let her know he would not be back for dinner yet again. She didn't raise any objection because she was happy he was socializing more, but it was obvious that she didn't like having to eat at her own place instead of at his.

After dinner, he went to "his room". Caster's Workshop.

"Hello Shirou," she greeted, her back turned to him while she busied herself with a cauldron of some sort, just like a bonafide witch. "How was your day?"

"School, homework, chores," the usual stuff.

She turned around and she had a smile on her face. If she had any idea of what was going to happen, she didn't show it.

"Hey, what's wrong?" she asked, seeing his expression. "You look troubled."

Oh, no. She was onto him. He needed to deflect.

"I heard that some people have wound up at the hospital. Unknown causes. Some died. It's the work of a Servant, isn't it?" he asked. He knew he couldn't lie to save his life. He needed to skirt the truth and not reveal his suspicions.

"Is that right?" she said with a slightly surprised expression. "Hmm. Yes it could very well be the case. Thanks for telling me this. I will look into it. Maybe I can track it back to the person responsible and deal with them."

Oh, she lied so smoothly that Shirou almost bought it. But they have been together almost two weeks now. He could tell that her response wasn't spontaneous but cold and calculating. She was brushing him off, and he needed to make her believe he had bought it, but he couldn't hide how he felt. He needed a believable excuse.

He looked down and away.

"I just wish I could do something myself," he said. Which was perfectly true, but not what he was thinking about.

She put a compassionate hand on his shoulder. "You are already doing plenty enough, Shirou," she said. "You are supporting me, and I promise you I will bring this war to an end as quickly as possible. Now, let me make you forget all about those awful things."

She leaned close and kissed him. He kissed her back. Soon enough their clothes were getting thrown off as they found their way to Caster's bed. She had somehow procured herself a king size bed, which was much better than any futon.

As usual, her clothes vanished with a thought and Shirou lay down between her legs, kissing his way up her thighs, back and forth, while she caressed his hair. Then, when he felt he had teased her enough he went for her womanhood. His lips found her folds and he gave her a long, wet lick.

"Hmm!" she moaned, grabbing his head. "Dear, you have gotten so good at this."

He had been doing this every night for two weeks now. Of course he had gotten good at it. But Caster seemed to be particularly impressed at his skill. He needed to make her climax as hard and as frequently as he possibly could.

He put all of his attention into eating her out, sucking her clitoris while he fingered her. The full treatment. Sure enough, Caster was quickly climaxing, squirting around his finger and on his face.

Even though this was a critical situation, and any minor slip up could result in him being killed or brainwashed, Shirou felt himself get harder. Which was great because failure to perform was not an option here. He freed himself of the constraints of his pants and pulled out his cock.

He saw the lust in Caster's eyes, when he dropped it on her stomach with a loud pap of skin on skin. She grabbed it with both hands giving it a few strokes and making it become even harder. She was biting her lip expectantly, eager for the pleasure it would bring her.

At that moment, Shirou did feel a little bit of pride. It was a very weird feeling for him. Or maybe not. He only found enjoyment in helping others, making them smile. And this feeling overlapped nicely with the desire to please a woman. Especially one as drop-dead gorgeous as Caster.

He pulled his cock away from her hands and rubbed it against her folds, wet and hot as they were. He put her legs over his shoulders and then slowly entered her innermost place. He saw his cock split her open by inch, and her face morphed in delight as he filled her to the brim with his flesh.

"Mhhaaa…. Gods, Shirou. You are the best," she sighed.

"A woman like you deserves only the best," he grunted, as he grabbed her hips. Then he pulled back and pushed back in. Slowly at first, but with increasing speed each thrust.

"Ohhh! Shirou! You are sooo good to me," she purred, running her fingers over his chiseled chest.

Shirou was emboldened by her words and kept increasing the speed of his thrusts. Each time he drove his cock to the very depths of her womanhood. He could notice a bit of bulge form on her abdomen when it was fully sheathed and she had the strongest reactions precisely at that moment. He had found her weak spot and he would bully it mercilessly, even if it meant being a little rough.

Instead of just merely thrusting he started ramming into her. He let loose all inhibitions and really, truly fucked her.

"Ahhh! Ohhh! Shirou… what's… what's gotten into you?"

"I can tell… I can tell you like it," he said.

"I do! Oh, gods! I do! Hmmm!"

Shirou kept giving it to her as hard as he could. Then with no warning he pulled out.

"Ahhh?! Why?" she lamented

"Turn around," he said.

Medea grinned and rolled over, getting on all fours and presenting her back to him.

"You have become so naughty, Shirou," she said, wiggling her ass enticingly.

"How could I not, with you as my lover?" he said, grabbing her hips and lining his cock to her folds again. He slid inside effortlessly. Her tight cunt accepted him immediately and soon he was already reaching the same intensity as before.

"Oh, yes. Just like that. I'm almost there…"

'Good,' Shirou thought and doubled his efforts. The time for action was about to arrive.

[br]

For whatever reason, Shirou was being extra passionate today. Medea didn't have any reason to complain though. She liked when a man took charge and wasn't just a fop full of nice sounding words (all references to real people were entirely intentional).

Really, Shirou was perfect for her. The right mix of cute, strong, malleable and dominant. She would have to watch out that he didn't get too cocky, but that wasn't an immediate problem.

At least, that's what she thought. Pierced by Shirou's cock, she felt her climax build up inside and she let it burst without hesitation.

"Nhhhaaa!" she moaned, arching her back.

Normally, at this point, Shirou would let her catch his breath, even if he still had to cum. Not this time, though. This time he kept pounding at her through her orgasm. "Ohhaaa! Shi- Shirou?"

"You are so hot, Caster!" he grunted. "I can't stop moving my hips."

"Hmmm! Waiiit! Ohhh!"

Being fucked through her orgasm made the sensation all the more intense. Her arms were trembling and she could no longer support her weight. She hugged the pillow, burying her face into its softness while her ass was sticking up and all the while Shirou kept pounding her.

'Oh gods. This is so good,' she thought to herself. In the past few days Shirou's prowess as a lover kept improving, but today was like he had flipped a switch of some sort and was being super assertive. She didn't hate it though. Far from it. She was squirting juice all around his shaft every time he thrust into her.

Soon, she felt the next climax come up much stronger than the one before. She was on the verge of release when Shirou grabbed her hair and pulled her head up.

"Ohh? Shirooou?"

She looked at him from behind her shoulder, shocked at the sudden rise in roughness. Her eyes widened as she saw him hold up his fist and the Command Seal etched onto its back.

Whatever reaction she was about to have was denied as she climaxed again.

"AHhhhn!" she moaned gutturally.

She was cognizant enough to understand that in that precise moment, she was one hundred percent vulnerable.

"Caster!" Shirou said, voiced deepened by the effects of the Command Seal. "I command you to never act against my wishes!"

He shot his load into her as he said those words. Such a broad order wouldn't hold much water in ordinary circumstances, but the power of the Seal traveled through their point of juncture using Shirou's semen as a vector. A Command Seal was powerful enough to force a Servant to bend reality to follow through with the order given. Reinforced by a tantric ritual and directed strictly at controlling the Servant's behavior, it was hundreds of times more effective than normal.

It went past all of her defenses, magical or otherwise, and seared itself directly at the core of her being: her Spirit Origin. She felt it crash into her mind and soul, irreversibly binding her. It was no longer an order enforced by the outside. Medea of Colchis couldn't act against Emiya Shirou's wishes any longer.

And to make matters worse, Shirou was still fucking her brains out. She couldn't even muster a negative feeling for the circumstances as she was being drowned in pleasure.

She had only enough presence of mind to formulate one thought.

'I lost. I lost to this boy and his cock. I'm completely defeated. Ohhhh!'

However, succumbing to a man had never felt so good. That pleasure was turning into something she wouldn't be able to give up. Whatever she would think about it later, she had already totally submitted to her one and only Master.

[br]

Shirou kept fucking Caster for another fifteen minutes, making her climax about a dozen times and ejaculating two more times into her for good measure. Only when he was sufficiently convinced he had gotten through her, did he gently set her down on the bed and slide his cock out of her.

Caster didn't move. She was laying motionless with the exception of the occasional twitch that caused his semen to squirt out of her pussy.

Shirou turned her over on her back and saw that her eyes were crossed over and had nearly rolled into the back of her head. Her mouth was stretched into a strange, almost insane smile with a bit of drool dripping from the side of her mouth. She looked somewhere between very happy and completely crazy.

Shirou was sincerely hoping he hadn't hurt her and that his strategy had worked out. If not, once she recovered he was most likely going to die. Well, there was nothing else to do but wait and see.

[br]

It took several hours for Medea to slip into proper unconsciousness and then sleep. When she started to wake up again, her body was still going through the aftermath of the intense pleasure. She felt so cozy that she didn't immediately recall how she came to be in such a way.

Only after a few minutes of staring at the ceiling did she start to piece her memories together.

She slowly pulled herself to a seating position and looked around. Shirou wasn't in bed next to her, but he was sitting cross-legged on the floor with his eyes closed. He opened them the moment he felt her gaze on him.

"Good morning," he said.

"Good morning…" she replied, licking her lips. "My Master."

He shook his head.

"Stop. I don't want your subservience," he said, getting to his feet.

"No? Then why did you use a Command Seal on me?" she asked, challengingly. She was actually surprised that she was allowed to talk back in any capacity.

"Because you lied to me. You are the one who has been draining Mana across the city. Don't pretend otherwise."

Her eyes widened. She didn't think he would have figured it out on his own. Everything made sense now. She looked away, ashamed.

"Yes…" she admitted. Not that she had much choice. "It was me."

"You knew I would have objected. And you did it anyway. Then you lied to my face when I brought it up."

She didn't reply and he made a frustrated noise.

"Alright, I will make this clear. You will never lie to me from now on. Not even by omission. Especially if you know it's something I wouldn't approve of. You will not do anything that would harm anyone, except in self defense against an immediate danger. You won't hide a thing from me. Is that clear?"

"It is," she agreed. If she used Rule Breaker on herself, she could get free of his control. However she knew perfectly well that would go against his wishes, and the command was entrenched so deeply into her that she couldn't even muster the will to rebel.

That didn't mean she was happy about it. Once again, she was someone else's puppet.

"Now, I want to know everything about you," he said. "Tell me your story."

And so she did tell him of her life of treachery and betrayal, both suffered and done to others, as well as her wish for a new life. The murder of her orginal Master, a complete piece of trash, and her meeting with Shirou along with all that followed.

"So, you didn't want to hurt those people?" he asked.

"It was an unintended side effect. I gain nothing from killing the people of the city. If they die they can no longer provide me with Mana. But I did not care if some passed in the process of tuning the system. It was an acceptable sacrifice."

That was right, she didn't care about them at all. She didn't hang her head in shame because she was remorseful, but because being compelled to be truthful made her feel vulnerable. Deceit and manipulation were her primary weapons, more so than Magecraft. And now she was stripped of them.

"What a damn mess," he sighed. "Do you have any idea which other Heroic Spirits we are going to face?"

"We?" she blinked. "...Do you mean that you still wish to help me?"

"Of course I want to help you. That never changed. And at least your real goal wasn't that far from what you told me. You just want to survive and live on. It's the method I object to."

"You don't care that I lied to you?" she asked. "Don't you hate me?"

"No, damn it. What good would it do to hate you? I just wish…. I just wish you had been honest with me and we could have found another way together. Do you hate me, for what I've done to you?"

She shook her head.

"I betrayed you; manipulated you. I was prepared to alter your mind to keep you compliant should you have raised a fuss. You saw through all of it and brought me to heel. That was the natural consequence of my own course of action. My mistake was not foreseeing the possibility that the Grail would choose you as a Master after you had already contracted a Servant."

"Why didn't you do that from the start? You clearly have the people here at the temple completely under your spell. Why not extend that to me?"

She hesitated for a brief moment, but the compulsion immediately forced her to speak.

"Because I wanted you to like me of your own volition, not because I made you," she replied and immediately put both hands over her mouth, looking away with her face red in embarrassment.

Shirou's face was also quite red.

"Uh… well. I guess that boat has sailed now. After what I did to you, there's no way you can still like me, right?"

She gritted her teeth as hard as she could from saying what she really thought and felt. Unfortunately, she truly couldn't oppose the Command Seal. It was far too powerful, and the truth slipped unbidden from her lips.

"No. If anything, I like you even more now. You showed me that you are a real man and that you don't have any problem taking charge of a situation. The way you used what I taught you to attack me at my weakest proves that you can be clever and sneaky when the situation calls for it. I respect that. But what made me really fall in love with you was the way you mercilessly bullied me into submission with your cock. It was both wonderful and cruel. Please kill me now."

The more her mouth ran, the redder her face became. By the time she was finally able to stop talking Shirou wouldn't have been surprised if smoke came out of her ears. He was much in the same state.

"Oh… uh… that's nice… I guess," he said. "I still like you too, that hasn't changed. I was just upset with you."

Medea was staring into her lap without saying a word. She was trying very hard not to think of anything lest she dug herself a deeper grave with her honesty.

"Look, uhm… you don't have to answer this question if you don't want to, but what do you expect our relationship to be like, going forward? What do you want it to be?"

With his express permission she felt the pressure in her mind lessen somewhat.

"I don't know," she admitted, still not looking at him. "I... I liked being made to submit to you. It felt really good. I would like to… to try more of that. Would you be willing to try?"

"Uhm, yeah. I… I didn't like forcing you back there, but if you liked it, I would like to give it a shot, yeah. You are so beautiful, I don't think I could refuse you most things."

This time, Medea's face flushed in a gentler way and her heartbeat settled into an excited yet tranquil speed.

"So… you'll be my Master in every sense of the way," she said.

"I… Uhm. Yes, I guess I will. But… only as long as you want me to. I won't force you to do any of that."

She nodded.

"I know. If you had such intentions you would have used the Seal to enforce my absolute obedience, instead of simply demanding not to be double crossed. You are kind even in cruelty. I suppose I like that part of you most."

He scratched his nose and looked away.

"Would you like to move in with me?" he asked.

"Eh? What? Move in with you?"

"Yes. You are my woman, aren't you? Then we might as well live together from now on."

"But… the temple is a lot safer. With the exception of the stairs, Servants can't get through."

"But that means that they'll expect to find you here, but they won't. Rather than fortifying, wouldn't hiding work better, while using the Boundary Field at the temple as a decoy?

"I guess, I could create a convincing clone of myself, or something, while I live at your place. If I'm not allowed to draw energy from the leyline, then most of the advantage of being here is lost. You do understand that in doing so you are going to drastically reduce our chances at victory?"

"Can't you just draw less power? Way below what would hurt anyone?"

"I suppose... It's ineffective but it can be done. Still, it's not as good a position as we might have. I'm a Mage, Shirou. Unlike other Heroic Spirits, my fighting power is strictly proportional to how much Mana I have at my disposal."

"What if you didn't have to fight?" he asked.

"What do you mean?"

Shirou held up his fist. "Since I got this, doesn't it mean I'm eligible to summon a Servant?"

Medea's eyes widened in realization.

"We need to prepare the ritual right away," she said, getting up to her feet. Sure enough losing full access to the leyline sucked, but the possibility of starting with another Servant at their disposal was much better.

Shirou got up and followed after her. This was just the beginning of their twisted relationship.
