The Dangers of a Witch's Staff

Ichasennin

Summary:

That night, at the Church, Shirou is too late and now he has to live in a world in which Caster won. But there's more surprises in store than he thought and just because he lost doesn't mean he's done fighting.

Notes:

This time as spinoff of UBW in which the counter attack against Caster doesn't go according to plan. Turns out that the Witch had one more ace up her sleeve.

Or between her legs.

For the records, this is an AU with no Kuzuki. Shirou is the only male involved.

Enjoy.

The Dangers of a Witch's Staff

Chapter 01

The front of the Kotomine Church looked like a warzone. The clash of the Red Archer and Blue Lancer resulted in mutual annihilation, and an eerie silence had fallen upon the place.

Inside the Church, however, groans of pain echoed through its halls.

"Saber… why?" Shirou asked.

Dressed in pure white, Saber stood silently with her invisible sword poised to protect Caster.

"I'm… I'm sorry, Shirou I… I cannot let you harm her."

Behind her, Caster smiled wickedly. Rin had collapsed at her feet, struck in the back of the head by the pommel of Saber's sword. She was still breathing, but she was out cold.

Shirou managed to get up and Projected another set of Married Blades. The fight was hopeless however. They had figured they could take the masterless Caster together, having counted on Saber resisting the command to attack them like she did before.

They had no such luck.

"Shirou, please. Stay down," she begged.

It was then that Caster said something unexpected.

"Don't kill him, Saber," she commanded. "I might have a use for him."

In a moment of desperation, Shirou threw the black falchion at Caster, but Saber intercepted it and swatted it down. Then, before he could do anything else, she decked him across the face and knocked him out as well.

He tried to fight against unconsciousness, but his battered body couldn't take any more abuse, and finally he passed out.

[br]

"Emiya-kun. Emiya-kun," someone called out from the darkness. "Shirou, wake up."

"Urgh..."

Shirou cracked his eyes open and checked his surroundings. He was chained to a wall in what he assumed was the Church's cellar. Rin was in a similar position to his right. Besides that, there was just a heavy looking door to his left and a huge mirror leaning against the wall opposite to them.

"Tohsaka… are you alright?" he asked.

"My head hurts, but I can manage. The biggest problem is that my Magic Circuits have been sealed. I can't do Magecraft anymore," she was trying to stay calm, but Shirou could hear a note of panic in her voice.

Tohsaka was a Magus at her core, and her craft was the one thing she could always rely upon in a crisis. She had probably never been so defenseless as far as she could recall.

"We… need to get out of here," Shirou replied.

"There's nothing we can do right now," she replied. " Don't try to use your Circuits either. You'll be ripped apart from the inside out. We need to wait for a chance. But even if we do get out…"

There was nothing they could do. Their Hail Mary attempt at turning the tables had failed. Even if they broke out, they were powerless to change the outcome of the War.

But Emiya Shirou wasn't the kind of person that gave up just because something was seemingly impossible.

"What happened with Saber?" he asked.

"Caster must have managed to break through her Magic Resistance," Rin explained. "She can't fight back anymore."

"There has to be something we can do," he said.

"There is not," Caster said, opening the door to the cell and stepping inside. As usual, the only visible part of her features was the lower half of her face. Her wicked lips were stretched in a victorious smile.

"Lancer and Archer have killed each other. Berserker and Rider are dead. Saber and Assassin are under my control, and that means I have won the Grail War. There is only that abnormal Servant left, but I already have a plan to deal with him."

"Why didn't you kill us then?" Tohsaka asked.

"What would I gain from that? You are no more of a threat than a kitten without claws. Besides, as long as I keep you alive, Saber will be more cooperative. Not that she can deny me anything."

"You'll pay for this," Shirou promised.

Caster smirked and grabbed his chin, forcing his head up.

"Perhaps I will, but not to you, boya. I gave you the chance to walk away and you blew it. You came for me, and now it is you who must pay the price for your folly. And you should know one thing," she leaned forward and whispered in his ear. "I charge outrageous interest."

She put a hand on his chest and pulled.

"AAGH!" he screamed.

"Emiya-kun!"

He thrashed in his bindings as something was ripped out from inside of him. It almost fought back, but eventually it had to give in. There was a flash of gold and blue light as something materialized in Caster's hand. It was a beautiful scabbard.

"Just as I thought," Caster smiled.

"What… what is… that…" he asked through ragged breaths.

"This is Avalon. The scabbard of the holy sword Excalibur. Saber's Noble Phantasm. This is the catalyst you used to summon her, though from your words just now I assume you didn't even know that much."

"But then… then Saber's true identity is…"

"Yes, the King of Knights. And with this her power will be complete. Thank you for delivering her and this to me, boya. You have been most useful. In fact, you have single handedly made my victory possible. I couldn't have done it without you," she mocked.

"Damn you…" he growled.

"Oh, so fierce. If only your bite could match your bark," she said, caressing his chin with a finger. "But unlike you, I know how to be grateful. Since you have been so helpful, I will show you something nice in return."

Caster waved her hand, and the mirror on the wall changed. It no longer showed a reflection, but another room entirely. There was a throne-like chair in it, and at its feet sat the white-clad Saber, looking like a defeated maiden.

"Saber!" Rin called out.

"Spare yourself the effort. She can't see or hear you."

"Leave her alone," Shirou demanded.

"You are in no position to give me orders, boy. The only thing you can do is watch. Both of you."

Caster left the cell and closed the door behind her. Moments later she appeared in the other room.

"Look at what I found," she said to Saber.

"A...Avalon… Where?"

"Inside of your former Master. Here, you can have it," she handed it over and Saber accepted it gingerly.

Saber cradled Avalon into her arms like it was a newborn baby, though at the same time she looked ashamed to be holding it.

"Why are you giving this to me?" she asked. "I could use it against you."

"You could, but you won't. Your friends are under my power, and if you misbehave it will be them who pays the price. Besides, you don't want to hurt me anymore, do you?" she asked, lifting Saber's chin.

Saber didn't answer, merely averting her gaze.

Shirou felt his chest constrain at the sight of Saber's silent submission. He knew then that her spirit was truly broken. She would not raise her blade against Caster again. What did the Witch do to make the proud knight act this way?

"That's what I thought. And since you have been such a good girl, I shall give you an appropriate reward. You do want your reward, don't you?"

Saber licked her lips.

"Yes."

"Saber…" Rin whispered. They couldn't believe what they were hearing.

And it was about to get much worse.

With a flick of Caster's hand, most of Saber's clothes vanished. Only the garter belt and stockings remained, which meant the only part of Saber's body that wasn't completely bare was instead accentuated.

But the biggest surprise was when Caster did the same with herself, keeping only her hooded cloak. However, it was not her nakedness that had Shirou's and Rin's eyes nearly pop out of their skulls.

It was the massive shaft sticking out from between Caster's legs.

"What the-?"

It was a grotesque thing, in stark contrast with the Witch's otherwise slender body. The fact that it lacked testicles was easily overlooked given that it was at least thirteen inches long and as thick as a grown man's arm. It wouldn't have looked out of place on Berserker's body.

"You know what to do," the Witch ordered, laying her phallus on Saber's face.

"Ah….Ahhh…."

With a dazed expression on her face, but without hesitation, Saber grabbed it with both hands and started stroking it while she licked the tip with her tongue.

The two captive Magi could only stare in flabbergasted silence, while the once pristine Saber lavished Caster's monstrous appendage with affection that bordered on worship.

She took the tip into her mouth and sucked on it, sliding one of her hands between her own legs while the other continued to stroke the massive shaft. This wasn't forced at all. Saber was pleasing herself as she blew Caster.

"You have become such a naughty girl in no time at all, Saber. You must have been very repressed. It took such little effort to make you my plaything. I didn't even have to use a Command Seal."

Saber said nothing as her mouth was full, but her face flushed red in shame. Nonetheless, she took more of Caster's cock into her mouth, bobbing her head back and forth and stroking steadily, while her fingers played with the folds of her womanhood.

Caster then put a hand on Saber's head, and forced her shaft into her throat.

"Grrk!" Saber groaned as her neck visibly expanded to accommodate the intruding mass of engorged flesh.

"Maybe if your previous Master had treated you right, you wouldn't have fallen so easily. But then again I don't think he meets the requirements to begin with, does he?"

"Emiya-kun, don't listen to her," said Tohsaka.

But Shirou could neither close his ears nor look away. The only thing he could do was clench his teeth and ball his fists.

Saber pulled her head back and released Caster's cock. A string of saliva still connected her lips to the shaft

"Please…. you have already beaten us. You don't have to humiliate them."

"How cute. Even though you betrayed him, you still wish to protect the honor of your former Master. Do you still harbor some resistance, my dear Saber? Perhaps I should get rid of them once and for all."

"No. Please don't do that."

"But how can I know that you are truly loyal to me, then?" Caster asked.

"You… you already know."

"Perhaps I do, but I have still never actually heard you say it. Maybe you are just letting me think whatever I want. If you want me to believe you, my sweet Saber, you need to show me. "

Saber hung her head and obediently got up. She walked to the wall from which Shirou and Rin were observing her, not knowing that she was being watched. She leaned forward and put both hands on the wall, like she was pushing against the other side of the mirror, before spreading her legs.

Caster chuckled.

"Well, I certainly don't mind this offering," she said, caressing Saber's butt. "To think it's only been two days since I had to chain you to this very spot. Do you remember how defiant you were?"

Saber gritted her teeth and said nothing.

"See, that's precisely the problem," Caster frowned. "You are still putting up a brave front. You are still making it seem like I'm forcing you to do this. But that's not the case, is it? I want the truth, Saber. From your own lips."

With tightly shut eyes and an expression of disgust for herself, Saber forced out the words.

"I… I want this. I… I submit to you with all my heart. I, Artoria Pendragon, swear my undying allegiance to you, and offer my body to do with whatever you wish. You are my one and only Master."

"Fu fu fu... That's very good. It's nice to finally know where you stand. Now, since you have been so honest and loyal I will give you what you deserve. What you want."

Caster lined her cock up to the entrance of Saber's ass, and pushed.

"Kh... hnnn."

Saber momentarily grit her teeth as if to suppress her own reaction, but her expression quickly changed into one of shameful pleasure.

"Hmm… such a tight little ass. So firm and soft. I'll never get tired of it," Caster remarked, thrusting in and out of Saber's anal orifice.

"Ohhh…." Saber moaned.

"What would your former friends think if they knew this is the reason why you betrayed them?"

"Please… don't…. don't tell them," the knight begged between moans.

"Which part shouldn't I tell? That you didn't lose to any Magecraft, but to the might of my big girl-cock? Or the part about you being a virgin anal slut who can achieve multiple orgasms purely through her ass?"

"Yes… Yesss!" Saber replied, but it was hard to say whether she was agreeing or just getting lost in pleasure.

"No, no, Saber. That just won't do," Caster scolded, grabbing Saber's hair and pulling her head back as the Witch continued to thrust into her ass. "You've got to state clearly what you don't want me to say."

"Ahhh…. don't tell them… don't tell them I'm… I'm an anal slut. Don't tell them… that I lost to your cock."

"Alright, I promise I won't speak a word of it," Caster laughed. "But on the condition that you tell me exactly why you like my cock so much."

She said this while increasing the speed at which she was pounding Saber's ass.

"Ohh… it's so big and… so hard. It's...It's reaching all the way to my stomach. It… feels so good… inside of me… So good inside my ass. I couldn't… I couldn't possibly win against it. Nobody can win against your cock."

"Maybe… or maybe you are just that much of a slut, Saber. Maybe it was all you were ever meant to be. My little cock-slave. Is that who you are, Saber? A slave to my cock?"

"Hnnng…. Yes! Yes! I was defeated by your cock and became its slave. I'm disgraced."

Saber's face was full of shame, but she spoke so enthusiastically. She knew that she was in the wrong, but she had fully accepted her new role. There was no deception. Saber had truly submitted to Caster.

"Saber. How could you…" Rin whispered.

"Don't buy it, Tohsaka. It's an illusion. Caster's trying to manipulate us," Shirou objected. "There's no way Saber would do something like that."

"R...Right," Tohsaka agreed, but it was obvious that she wasn't clinging to that hope.

Caster had no reason to deceive them. Anything she wanted from them she could get. They had no defenses against a mage from the Age of Gods. She could literally twist their minds however she wished.

She didn't need illusions to convince them of anything. She could just make it happen. She was doing all this exclusively for her own amusement.

Someone as practically minded as Tohsaka Rin couldn't buy a convenient lie like Shirou would. And if someone as strong minded as Saber had been beaten and broken, what could they possibly do? Nothing on top of nothing. Especially without Magecraft.

Shirou couldn't know, but it was that moment when Rin had started to accept her own defeat as well. But her pride wouldn't let her admit it so easily, even to herself. But even if Shirou could read the emotions on her face, his eyes were still drawn to the scene displayed in the mirror.

Caster had lifted Saber's body off the ground, holding her legs up in a spread-eagle position as she fucked her, and thus giving the Magi a perfect view of her monstrous shaft going in and out of Saber's ass. They could also clearly see Saber's belly distending slightly with each thrust, proving that she had not been exaggerating when she claimed she could feel Caster's cock all the way up to her stomach.

And Saber was squealing, cupping her own face like a shocked maiden.

"Yes, you are mine, Saber." Caster grinned. "And I'll provide you plenty of ways to prove your commitment. But for the time being your only task is to receive my seed."

"Hnng! Yes! Your hot semen. Give it all to me. AHHN!"

Saber threw her head back when Caster made one final thrust. Her exposed womanhood shot love juices all over the mirror, as if to prove the reality of Saber's climax. What could be seen of Caster's cock was throbbing visibly, and a moment later thick, white cum dripped out from where their bodies were joined. Saber herself was twitching and breathing heavily.

She would have been tremendously beautiful if the situation wasn't so incredibly horrible.

"You have been excellent, Saber," Caster said, sliding out from the other Servant and lowering her to the floor, where she laid face down with her ass up. Her body was still twitching in the aftershock of her climax, and her gaped asshole was quivering even as Caster's cum continued to spill out of it. "I will acquiesce to your wishes and not say a word of what transpired to your former friends. And if you keep being so obedient, I might even let you talk with them."

"Tha… Thank you for… for your leniency."

"Hmm, I wouldn't want to make my favorite slave cry, would I?" the Witch smiled, her cock still hard. "Now, when you are done there, you can come find me in my quarters. As much as we'd both enjoy it if I just kept fucking your ass forever, there are plans we need to discuss."

"Yes… my... Master," Saber replied.

There were tears flowing down her face. Saber herself was disgusted at what she had done, what she had become.

Shirou was clenching his teeth so hard that a drop of blood fell from the corner of his lips.

"Tohsaka, you said that Caster sealed our Magic Circuits?"

"Eh…? Yes, she did. Why, what are you thinking?"

"No, nothing," he replied. He would have asked, but there was no way of knowing if Caster was listening in on them.

It was their last thread of hope, and as much as he wanted to use it now and rush to Saber's side he had to wait for the right moment. If he failed then it really would all be lost.

After a few minutes, Saber picked herself up and wobbled after Caster, disappearing from their vision. The mirror kept displaying the other room, but there was nothing for them to see anymore aside from a puddle and subsequent trail of cum that had dripped out from Saber's asshole. A reminder of what had occured.

"Emiya-kun, what are you planning?"

"I'm not planning anything right now," he replied, which was true.

He only had one trump card, but no idea when to use it.

"Don't do anything stupid," Rin warned.

Shirou didn't answer. Anything he would do from this moment onward could only be called stupid. The opposition consisted of three Servants, one of whom he would never hurt. Even a single one of them was more than he could take. His only advantage was that they didn't know he wasn't completely defenseless yet.

But whether that would be enough to turn the tide, remained to be seen.

The Dangers of a Witch's Staff

Chapter 02

Eventually Caster allowed Rin and Shirou to be released from their chains. They were left alone inside the room with the mirror and the door was wide open. However, they couldn't get out as a Boundary Field kept them contained.

They had all the strict necessities required to live, even a full bathroom adjacent to their cell as well as two beds had appeared out of nowhere at one point.

But that was it. They hadn't seen or heard from Caster and Saber in… well, they didn't know how long. It was difficult to gauge the passing of time underground. Judging by the number of the meals delivered by Caster's skeleton soldiers though, it should have been about three days. But that was going with the assumption that they were fed at regular intervals, which they had no way of knowing for certain.

Rin and Shirou didn't talk much. In fact, they didn't exchange so much as a word during the last day. After a while, they ran out of topics to discuss, and they couldn't even make any kind of plan to break out. Even if they had a one in a million chance to make it, they couldn't talk about it for fear of the very real possibility that Caster was listening.

The persistent silence made the passing of time even slower.

Eventually, however, a visitor came to see them.

"Shirou. Rin."

"Saber," Shirou said, getting up to greet her.

She was dressed in the same white garment from the last time they saw her and she carried two bowls of soup.

"How are you feeling?" she asked.

"We are fine. We aren't hurt anywhere," Shirou replied, taking the bowls from her hands. "Right, Tohsaka?"

Rin didn't answer. She sat on her bed with her knees brought up to her chest. She wasn't even looking at Saber at that moment.

"Tohsaka?"

"It's fine," said Saber. "Indifference is the least a traitor like me should expect."

"It's not your fault, Saber. It's mine, if I were a better Master than you wouldn't-"

"Stop it," Saber objected. "I have unquestionably betrayed you for my own selfish reasons. From the depths of my heart I chose Caster over you. That is all there is to it. If you truly wish to be merciful, then please despise me. Your kindness is only painful to me right now."

"Saber…"

It was then that Rin scoffed.

"From the depths of your heart?" she asked. "Since when has your heart resided in your butt?"

"Eh?"

"Tohsaka! Enough!"

"No way. I'm not like you, Emiya. I call things for what they are. Besides, it's what she called herself in the first place. What was it again, Saber? Caster's cock-slut?"

Saber's already fair skin turned even paler and a distraught expression twisted her features.

"That woman…. she promised she wouldn't say a thing."

"Oh, she didn't tell us a single thing," Rin replied. She pointed at the mirror, that was against the wall opposite to them and behind Saber. The same mirror that still showed the room in which her admission had taken place, and the dried puddle of Caster's cum that had spilled out from her asshole.

When Saber realized what she was looking at, she understood what had happened.

"Your secret was already exposed before she made the promise," Tohsaka goaded. "That's what you get for being a shameless skank."

"Tohsaka! That's enough!"

"Yes, that is indeed enough."

Caster's figure materialized into the room out of a cloud of dark smoke.

"I'm the only person who can bully Saber, little girl. You better not forget about it."

"Tch! Like you didn't show us that stuff precisely because you wanted us to bully her for you," Tohsaka retorted.

"Ah, yes that's exactly the case. Yet despite knowing that you were playing right into my hand, you still hurt Saber for your own satisfaction. You had the choice not to, but you did it anyway. You are not so much better than her after all; going against your principles and hurting those you care for to satisfy your own desires. So similar, yet you are so quick to judge."

"I'm nothing like her!" Tohsaka protested, getting up on her feet.

"Oh, why don't we put that statement to the test then?"

Caster moved forward and grabbed Rin by the neck, easily lifting her off the floor.

"Tohsaka!"

Shirou moved to intervene but he was suddenly pushed to the ground by Saber, who pinned his arms behind his back.

"Saber! Let me go!"

"I can't do that, Shirou. I would rather not have to harm you. Please, stop."

Shirou's body shook. He couldn't get Saber off him no matter how much he struggled and a moment later Caster vanished the same way she appeared, taking Tohsaka with her.

Only then did Saber release him.

Saber stepped back and retreated to the doorway.

"What is she going to do with Tohsaka?"

"Whatever she wants," Saber replied.

"Saber… are you really on Caster's side after all?"

"Yes," the Servant admitted, looking down at her feet. "The relationship you and I shared is already a thing of the past."

Something twisted in Shirou's chest, but he could see the resolve in Saber's eyes. She meant those words even though they pained her. He clenched his teeth and balled his fists but there was nothing he could do. No words he could say would change what had already happened.

"I care about you, Shirou, but she's everything to me now. Do not think of me as your friend any longer. If you can't bring yourself to forget what once was, then I implore you to despise me. You will hurt us both if you don't."

She stepped out and closed the door behind her, leaving Shirou in the cell with only his own powerlessness for company.

[br]

Deep within the dark depths of the church, the cries of a young woman echoed. In the flickering light of candles, flashes of pale skin could be seen moving, squirming.

Slowly, the cries turned into moans and the squirming into a slow, sensual dance.

No one witnessed any of this, except for the two participants. The dance went on and on, for what seemed like an eternity. When it finished, only the sound of long, ragged breaths and dripping fluids remained.

[br]

Once more, time turned into an indiscernible blur. How long had it been since Rin had been taken away?

Two hours? Four? Shirou couldn't be sure. He paced the room until his legs started to hurt and that meant he had been at it for a very long time.

Could he have intervened back then? Not while Saber was behind him. It would have ended up precisely like it had. He had precisely one shot and had to make it worth it. He had no confidence that he could break out of the Bondarary Field without raising the alarm.

And of course he wouldn't escape without Rin even if he could either.

And with nothing but time on his hands, his mind kept replaying what had happened to Saber, wondering if Tohsaka was going through the same thing or if Caster was doing something even more devious.

His hands were bleeding from how much he had dug his nails into the palms.

Normally he would have tried anything to rescue Rin, even if it killed him, but he knew that if he failed no one would be able to save her. He was put in the difficult position of having to care for his own life, because that was the best chance to save Rin.

But it was eating him from the inside out.

Then at some point, the door opened and Tohsaka stumbled inside, held up by Saber.

"Tohsaka!"

He rushed to her and Saber gently passed her to him, but Rin gently pushed him away and stood on her own.

"I'm fine," she said. She looked like she had been through hell.

"What did Caster-"

"I don't want to talk about it," she replied.

She stumbled to her bed, where she curled upon herself.

Shirou turned to Saber, who stared back with the barest hint of sadness on her features. She shook her head.

"I don't know any more than you do. My Master only ordered me to escort her back here. As for transpired between them, I wouldn't begin to speculate. She's nothing if not creative."

That didn't reassure Shiou in the slightest, and yet what was he supposed to do? He wouldn't force Rin to speak of what happened. He wasn't even sure he wanted to know in the first place. It wasn't like he could undo it.

What was he even good for, if he couldn't help in the smallest of ways?

"Shirou," said Saber before closing the door. "I want you to understand that none of this is your fault. Don't blame yourself. There is nothing you could have done that would have made a difference."

Your actions are irrelevant, and all your efforts amount to nothing was what she was telling him.

Saber's words were spoken out of kindness, but they only tore a bigger wound in his heart. He wasn't looking for disculpation but for a purpose, and she just stripped him of it retroactively.

It was worse than any injury she could visit on his body, and she didn't even realize what she had done.

Saber closed the door and left. Even though Rin was back, Shirou felt more lonely and powerless than ever before.

[br]

For the rest of the day, Rin didn't so much as utter a word to him. Saber came by to bring them their meals again, and they consumed them in silence. Again, he had no idea how much time had passed, but at some point he fell asleep.

When he woke up, the first thing he noticed was that Rin's bed was empty. He immediately sat up but then he heard the sound of running water coming from the bathroom and he relaxed immediately.

He wanted to see how she was faring so he laid back down and waited for her to come out but he wound up dozing off again. When he realized it and reawakened, she was already back in her bed. At least it seemed to be the case, because she was completely under the covers. He couldn't even see her head.

He got up and went to check on her.

"I'm fine, Emiya. Leave me alone," she said before he could even nudge her.

He took back his hand. It wasn't going to get any better this way and even though he wouldn't admit it, he was starting to get desperate to do something . Inaction had never suited him and the frustration was starting to get to him.

He needed to do something as soon as possible. If he waited any longer, things would only get worse. He would act at the first possible chance, no matter the consequences to himself.

After that, the passing of time became a real sludge.

Still without any way to tell the time, Shirou estimated at least one week had passed since they were first captured. During this period, the only thing of note that changed was that Rin spent a lot of time in the bathroom whenever Shirou slept.

He kept himself in shape by exercising as much as he could, and then the occasion he was waiting for finally came.

That day (or was it night?) the door to their cell opened and Caster walked in, alone.

The two captives immediately got to their feet and Shirou immediately put himself between Caster and Rin.

"Ara? What is this, boy?" asked the Witch. "Are you still looking for trouble?"

"What is this about?" he asked. "It's not like you to come for a social visit."

The witch's mouth, which was the only visible part of her face under the hood, quirked into a mocking smile.

"Are you really sure about that? Anyway, I believe it would only be thoughtful to come and thank you both."

"...What for?" he asked suspiciously.

A hand emerged from the darkness of her cloak, holding up a golden cup. Now that it was no longer hidden Shirou could feel the power radiate from it.

"Is that…?"

"The Holy Grail, yes. There have been more nuisances than I had expected, and cleaning it up from the impurities it had inside of it wasn't a simple task, but now it's done. The Grail War is over and I have won."

"Where is Saber?" he asked. "Is she hurt?"

Caster looked surprised. "Are you still concerned about her after what she did to you? I'm not sure if your behavior is more endearing or idiotic. Nevertheless, she is perfectly fine. She has behaved admirably during this conflict and thus I decided to reward her. She's now busy enjoying my gift."

"What have you done to her?" he asked.

"Emiya-kun, calm down," Rin said, putting a hand on his back for comfort.

"Nothing that she doesn't like, boy. As you very well know, she's very happy with the life I have given her. But if you really want to know how she's doing, let me show you."

She turned halfway to the mirror on the wall that was still showing the other empty room. The moment her eyes were off him, he acted.

"Trace on!"

His Circuits were sealed, but Caster didn't know that he had only started to use them recently. For the previous ten years he always made a new Circuit out of his nerves, and those were not sealed because they didn't exist until he made them.

The white curved sword, Bakuya, appeared in his hand. Caster was in the middle of the spell to control the mirror's image and that gave him the split second opening he needed. At this range it was more than enough.

One blow. All he needed was a single blow to turn the tables.

He could already see the trajectory of the blade, headed for the Witch's neck. She turned but it was too late for her to stop him.

And then his vision blurred. His sense of balance was disrupted and he crashed to the floor. A spell from Caster hit him a moment later and he was immobilized as he laid on his side.

His vision stabilized and what he saw chilled him. It was Rin with her elbow thrust out. She had hit him in the back of the head.

"Ah…" she said, seemingly realizing only then what she had done. "I… I'm sorry. Emiya-kun. I'm sorry."

"Toh...sa...ka…"

"You wretched worm !" Caster raged and Shirou's body was wracked by bolts of lightning.

"GAAAAHHH!" he screamed. His mouth was the only part of his body that could move. He couldn't even trash around while his body was hit by this magic storm.

"I show you mercy. I gave you a chance to live, and you have spit on my generosity time and time again!"

"Stop it! Please, stop it!!" shouted Rin, throwing herself on top of him and getting hit by a few spells as well.

Surprisingly, that got Caster to stop.

"What… have you… done to… Tohsaka?" he asked between gasps.

Caster seemed taken aback.

"You… At a time like this, when I'm this close to turning you into pig food, you are worried about someone else?"

"What… did you…"

"Hpmh! The same thing I have done with Saber, of course. Why do you think she would have defended me otherwise?"

"Re...lease… them…"

"Release them?" she asked, surprised. "Do you believe they are under a spell? Hm. How amusing. You are a fool denying reality. No wonder you are fighting back still. I had no interest in you and I intended to let you go now that the war is over. But since you are so utterly disagreeable perhaps I should instead give you a first hand taste of said reality."

"Wh...at?" he asked.

" Sleep now ."

He was hit by another spell and darkness claimed him.

[br]

"Hn…"

Shirou slowly returned to his senses to the feeling of something cold and hard around his neck and limbs. As his consciousness returned, he realized that he was suspended in mid air by chains wrapped around his body.

"What…?"

"You are awake at last," said Caster from behind him.

His bindings made it impossible for him to turn, and having her at his back filled him with dread.

He struggled against the chains, but it would take far more than what little strength he could muster to break free. If he made a Nerve Circuit again perhaps he could, but Caster would react before he could do that and he knew it.

"What do you plan on doing?" he asked.

"I want to make a deal with you," she said. "Or a bet, if you prefer to think of it that way."

Shirou was immediately wary. Making a deal with a witch was barely one step removed from doing so with a devil. However, he had a severe lack of options at that moment. Of course, she was just playing with him and he knew it.

"What kind of deal?" he asked.

"You see, Saber and Rin have been literally begging me non-stop not to kill you as I honestly should. They really care about you, you know."

"Kh!"

Shirou was furious. The image of the two girls prostrating themselves before Caster to beg for mercy on his part made him loathe himself even further.

"I understand you think I am a monster, but I'm not without compassion. Their earnest groveling moved my heart a bit. Thus I decided to give you a chance."

He gritted his teeth.

"Get on with it."

"Don't be so hasty, boy. First of all, you need to understand that no matter whether you take my deal or not, I will let you walk free at the end of this, should you choose such."

"What? Why would you do something like that? "

"I had Rin explain to me in great detail what you did, and the extent of your abilities. I can safely say that even your talent to replicate Noble Phantasms is no threat to me now that I have the Grail and Saber. Your best chance at killing me was your recent assassination attempt. And I have since put a few fail-safes on you, just in case you try your luck again."

"Even so, why let me go?"

"Well, the long and short version is, because it's more fun this way ."

"...What is this deal of yours?" he asked.

"Oh, it is fairly simple," she chuckled. "I will do to you the same thing I did to Rin and Saber. By the end of it, if you still decide to leave, I will offer Rin and Saber their freedom as well."

"I don't believe you."

"Oh? When did I ever lie to you, boy?" she asked. "I have always been honest about my intentions and I have always kept my word when I gave it. I may be a Witch but I am a Heroic Spirit as well."

Shirou had no way to refute that. His distrust of her came from their wildly different morals, but it was true that she had always held up her end of a bargain from what he'd seen.

"I'll even sweeten the deal for you," she said. She put her arms around him from behind and cupped his face as she whispered in his ear. "If you are willing to make an additional bet that you won't climax before I do, and win, I will even give you the Grail. Then you can use it to reverse what I did to Rin and Saber. It will be like nothing ever happened."

"!!!"

The past couldn't be undone. It simply went against common sense. But the Grail was literally a wish granting device that made the impossible possible. If he could trust Caster to keep her word, then he had a chance of fixing everything. Rin and Saber would be saved.

"On the other hand, if you accept this additional wager and lose, I will put a curse on you."

"I accept. All of it," he said instantly.

"...You didn't even think about it for a moment," she said, clearly shocked. "You don't even have a clue as to what the curse could be."

It didn't matter. In the first place, he was the only person that stood to lose something from this agreement. Of course, he didn't think for a moment that Caster would cheat. If she wanted so badly to win, she didn't have to make a bet with him in the first place. He was already completely at her mercy.

The reason why she proposed this deal was because she believed she wouldn't lose. This entire affair was only for her own amusement.

And yet… he had to take it. Even if the deck was completely stacked against him, it was still a chance. His chance to fix everything. To save everyone.

"Are you really sure you want to go through with this? I won't have any complaints or take-backs from you later on. If you agree to this now but end up changing your mind in the middle of it, I won't stop even if you beg me to."

"What's with the sudden concern?" he asked. "Afraid you'll lose?"

"Fuhuhu," she laughed. "If you really do manage to hold out until the end, I wouldn't mind losing."

She pulled away and the chains that bound him vanished, dropping him to his knees. Before he could get up, Caster put a hand on his shoulders and kept him there as she walked around him.

"Now then… shall we begin?"

Like before, her clothes vanished except for her cloak that still concealed her features. With the constraints of her dress gone her enormous dick, already erect, fell and impacted on Shirou's face.

He recoiled immediately.

"Ah ah!" she chided. "We have already made a deal, boy. Whichever one of us climaxes first loses. If you pass on the opportunity to work it with your mouth, you'll give up the advantage. Are you going to still hold onto your pride, or are you going to swallow it and my cock? And don't forget that when I move from this spot that it will be to plow your tight, virgin hole. Do you want me to do so completely dry?"

Shirou honestly would rather that she fucked his ass dry than willingly suck her off, but it wasn't just his body at stake here. As much as he hated this, as much as he found it humiliating, he had to do it.

"Rin and Saber had to as well, didn't they?"

"Fuhuhu, they certainly did."

"Fine then," he replied.

It was his fault that they had to go through such humiliation. If he wasn't so useless, they wouldn't have had to suffer such a fate.

He suppressed the disgust and grabbed her appendage. He forced himself not to think of how it felt in his hand. He killed his emotions the same way he did in preparation of making a Nerve Circuit, and committed himself to the distasteful act.

"As a man, you should know better than Rin and Saber how to handle it, right?" Caster asked with a gleeful smile.

He didn't answer. He didn't even let it show on his face how much he would have liked to cut off her dick right there and then. He suppressed it all and started stroking it.

It wasn't like doing it to himself. The angle was completely different for one thing, but going with the assumption that the sensitive areas were the same, he put his focus on the crown, circling it with his thumb.

"Ahh… as expected, you are an expert hand at this. You might prove to be more of a challenge than Rin, at least."

"I don't need to hear you speak," he said.

"Such bile. Do you think I forced them, hmm? I offered them a similar deal to ours and they both lost. In particular, Rin threw herself at the challenge several times. But perhaps you didn't know that."

"What are you talking about?" he asked, glaring at her.

"I paid a few little social visits as you put it to your cell in the past few days. Every time Rin locked herself in the bathroom, she invited me to join her. Each time, she challenged me saying this would be the time she would win. Rin sincerely seemed to believe that she could prevail against me if she just… got more practice. And to be fair she did last longer each time. But truth be told, I'm pretty sure she just wanted me to plow her again but couldn't bring herself to admit it. That girl is not very honest about her feelings, is she? Although her true heart got revealed when it mattered most, so I don't think I can complain."

"Shut up," he said.

"Aw, you poor boy. It can't be easy knowing that the girl you like fell in love with the cock of the enemy and betrayed you for it."

"Shut up," he said again. He didn't want to hear her lies.

Except… she never lied to him. So she wasn't lying even now and he knew it. He had to believe she was being a hundred percent truthful, because if she wasn't then what he was doing now would be even more pointless.

Shirou's heart shattered into a million pieces. He liked Rin. Heck, he could say he loved her even. He had made his feelings for her pretty clear, and she had still betrayed him to Caster.

Just like Saber had done before her.

Any man with a shred of pride and self respect wouldn't have subjected himself to what he was doing now for two women who already betrayed him. But Emiya Shirou had no such things, so even though his heart was broken he would still do it for them.

"You know, you can still back down," said Caster. "You can pick the first option and just leave. Saber and Rin will stay with me, of course, but deep down you already know, they have chosen me over you. Are you so certain that you won't do the same by the end of this?"

"Like I said, shut up ," he repeated.

"Resolute. I like that. But if you are going to just repeat the same words over and over again, I have a better use for your mouth."

She took her cock out of his hand and placed it against his lips.

"Lick it," she commanded.

'...I have to do this.'

Although his disgust had only gotten worse, Shirou had already chosen this course of action and wouldn't back down now. If he got the Grail he could change everything back to normal, and that was worth any cost to himself.

'As long as I win, everything will be washed away.'

He opened his mouth and his tongue came out, making contact with the skin of her hard member. He forced himself not to retch and instead run his tongue over it.

"Oh, this is pretty nice," she said. "I'm not usually into boys, but I must admit that you've got to have a dick to truly know how to please one. Still, it's pretty clear you've never received fellatio yourself. Unsurprising, since Rin told me you two didn't go past holding hands. Have you even kissed a girl yet? Fufufu. Don't tell me that you gave your first kiss to my cock?"

Shirou glared at her while he kept running his tongue up the length of her shaft.

"Ahaha! Oh gods. You did! What a pathetic excuse for a man. No wonder Rin and Saber betrayed you so easily."

' Damn this Witch. Damn her to hell,' he thought.

It wasn't easy to find a way to hurt Shirou's pride, seeing he had so little of it. But Caster managed to find it and trample upon it with trivial ease. She made him feel even more small and insignificant than he already did.

There was a sting behind his eyes, as if he was about to cry. He suppressed it. He wouldn't give her the satisfaction of knowing she had hurt him.

In response she just put a hand on top of his head, almost as if petting him. "Good boy, you are starting to learn your place. If you beg me, I might consider keeping you, provided that you also do a good enough job of satisfying me."

Shirou ignored her. He did what he had to do. There was too much at stake for him to let her play with his mind any further. This was her game. Humiliating him was precisely what she wanted and he wouldn't give her the satisfaction. Instead he focused on working her shaft more.

He grabbed it with one hand and started licking it fervently. One would think he was being passionate, but that would be a mistake. He was simply attacking an opponent using the weapons he had available with no regard for his own dignity.

"Ohhh…! What's gotten into you? Even Saber didn't show me this much devotion until after she surrendered to me. Ahhh… I see now. You are secretly a little masochist faggot. That explains why you would persevere for years making Nerve Circuits. You crave physical and emotional pain."

Shirou didn't reply, of course.

She could believe what she wanted. Protesting would only make her twist the knife deeper into the wound.

"You might actually be the most difficult of the three to deal with," she admitted. "Neither Rin nor Saber put in this much effort their first time. They thought they could hold out and outlast me just by gritting their teeth and putting up a brave front. I had to teach them the kind of pleasure my cock could give them before they really got into it. They weren't born cock-craving sluts like you."

At this point, Shirou's emotions had become so twisted that nothing she said had any effect on him any longer. He just did what he had to do. Until Caster stopped him, that is.

Before he could ask what she wanted, she pushed the tip of her cock between his lips.

"As much as we've both enjoyed you lavishing my cock with your tongue, it's time we moved things along. Now suck it, boy. Suck my cock like the little bitch you are."

Shirou was already past the point where he would express open defiance. In this insane battle, fighting back had become making Caster cum as fast as possible, and he would take any opening she gave him without hesitation.

He didn't even glare at her this time. Instead he closed his eyes and opened his mouth as wide as he could before pushing his head forward, accepting the head of her cock into his mouth. He obediently began blowing her, bobbing his head up and down on the upper part of her shaft.

"Hahaha! Ohhh. Look at you. No wonder you didn't even get to first base with Rin. A loser like you never had a chance with a woman like her. You've actually spent your whole life waiting for someone like me, haven't you? You're attracted to women, but you really want someone with a nice big cock to put you in your place. I guess that means I'm everything you've ever wanted."

She grabbed both sides of his head and pushed her member deeper into his mouth.

"Oh, yes! That's a good look for you, boy, on your knees with a fat cock between your lips."

She rocked her hips back and forth, pushing and pulling her member in and out of his mouth.

Shirou could only accept this abuse, even though his jaw was nearly dislocated from how stretched it was.

"Oh, you're such a good boy. Not even a peep of displeasure from you. I can't believe this is your first time giving a blowjob. Be honest with me, you have been sucking cocks for a while now, haven't you? I'm told that the life of a student is very stressful in this era. I'm sure that some of your schoolmates have been very happy to use your mouth as a means of relief."

Shirou couldn't answer in any way. Her cock was stretching his mouth so much that he couldn't even shake his head a little, much less deny it vocally.

"How many boys did you blow in the restrooms and locker rooms, hmm? Did you lose count? For you to have a mouth like this, there had to have been a long line whenever you offered your services. Did you ever have to skip classes to suck them all?" she continued, but she started to speed up how fast she was moving her hips. "How silly, I'm sure you did. Once a faggot gets ahold of a nice cock, there's no way they would let it go, right? Just like you are doing right now."

Shirou's lips were firmly wrapped around her shaft as he was applying a fair amount of suction to her, and she'd managed to fit a third of her length into his mouth.

"It's fine to admit it. It's not like I could possibly think any less of you," she said. "You are either an experienced cocksucker or a natural one. It doesn't make much of a difference in the end. Hmm… I would love to feed you my semen right now, but that would be my loss."

She pulled out of his mouth and Shirou could finally breathe properly for the first time in a while. His face was flushed from the abuse and there was a thick string of saliva still connetting his lips to Caster's cock.

"Ahh… I know I said I'm not really into boys, but I underestimated how cute you could be under the right circumstances."

"I don't… care…" he replied defiantly. "Just get on… with it."

"Fuhuhu… I truly want to see if you'll be of the same spirit once I'm done with you," she said. "Or if you'll prostrate yourself before me like Rin and Saber have and beg to serve my cock for life."

She snapped her fingers, and the chains that had disappeared returned, wrapping around Shirou and lifting him off the ground. He didn't offer any resistance.

Caster walked around him again and groped his butt.

"Hmm… so firm. You have been diligently training your muscles for years, haven't you? Honing and sculpting your body so that it could serve you well in times of need. And now… now all that effort is going to make you into a very tight cock-sleeve for me."

She tapped his belt, and the bottom half of his clothes disappeared, leaving him naked from the waist down. She pushed herself against him, embracing him from behind. Her huge erection pressed menacingly against his back. She rubbed her shaft up and down against the crack of his ass.

"I'm going to reshape your tight little asshole to fit my cock like a custom-made glove," she promised as she caressed his face, before pushing her fingers inside his mouth.

"Mgh?"

She grabbed his tongue and rubbed it between her digits, coating them with his saliva. Then she pulled out and pulled back, reaching for his ass with her wet fingers.

"Be grateful, I'm going to loosen you up a little bit," she told him, before gently sliding two of her fingers inside his butthole.

Shirou gritted his teeth at the intruding presence. It was the first time anything had been put in there, and it was both uncomfortable and humiliating.

Caster slowly fingered his ass until she could fit four of her digits inside him, and as she did so his body grew accustomed to the sensation. Worse than that, each time she slid her fingers inside she rubbed against something that sent sparks up his spine. Against his will, his dick rapidly started to harden.

"Ahh, what is this I see here? I barely started to tease you and you are already like this?"

"Shut… up…" he groaned, but his voice was cracking.

"Fufufu…. It's alright. You aren't at fault. You were born with a tiny dick that gets erect with the slightest anal stimulation. It's just the way you are. You know, I could make you cum with just my fingers right now. Make you shoot your useless seed all over the floor where it belongs. I know you'd like that, you little masochist faggot, but I'm not done with you yet."

She withdrew her fingers, but that didn't give him any relief. He knew that something much worse was about to happen.

He felt the tip of Caster's thing press against his sphincter. She might have loosened and lubed him up a fair bit, but the size of that thing was just so massive . She pressed harder against him, and Shirou could only grit his teeth as his butthole was forcibly stretched open while her gargantuan appendage entered him. At last, she stopped, and he gasped for breath.

"Struggling already?" she asked. "It's only the tip, you know?"

"Wha-kk!"

She pushed onward, slightly faster than before and he could feel every inch of her meat slide into his body, stretching him in every direction.

"Kh-ah…!"

The pressure was intolerable and if he hadn't been chained so firmly, he would have fought to get himself off it. But in his current situation he could only suffer as she thrust her cock upward inside of him.

At last…. At last he felt her hips touch his buttocks and he knew he had made it.

He was packed so tight, so full , that he could feel Caster's heartbeat inside of his stomach. He couldn't even draw a full breath as his diaphragm couldn't expand more than a little bit.

Caster put both arms around his torso holding him close to her chest. Her breasts were pressing against the back of his shirt. It might have appeared to be a comforting gesture, but he could feel her smirk pressing against his ear.

He knew the reason for her smile. She was a person who reveled in betrayal, so she was greatly amused with the knowledge that Shirou's own body had betrayed him.

That's right, even though -no, because his asshole was being violated, his own cock was standing hard at attention.

"Do you understand now?" she whispered in his ear. "It's just like Saber said: Nobody can win against my cock. This is the reason she and Rin betrayed you. They abandoned everything they stood for and pledged themselves to me so they would be able to experience this over and over again. And judging by how much your body is already enjoying this, so will you."

He turned his head ever so slightly, even though any movement he made was uncomfortable.

"Is… running your mouth… the only thing… you are good at?" he asked.

From the corner of his eye, he could see her smile stretch even more.

"You be the judge of that."

She drew her hips back and her cock followed along. Shirou had just been starting to adapt to its presence inside him, and the sudden extraction made him feel like his body was almost deflating. Only for it to inflate again when she pushed it back inside.

"Agh!" he groaned. "Aghh!"

She continued to move her hips, and with each repetition Shirou's body became progressively more accustomed to the violation.

To be perfectly clear, that was not a good thing . The more his body adapted to the suffering, the more it accepted it, the more Shirou became aware of the other sensation being forced upon him. The pressure and friction against that spot that made his manhood's betrayal of his wishes only become more prominent.

"What's wrong? You haven't made a sound in quite a while. Could it be that even your voice would betray your true feelings?" she asked mockingly without ever ceasing her thrusts.

"Nah," he replied, his voice steady and stone cold. "I just figured that there's no reason to play your mind games."

For a brief moment, he saw a flash of genuine surprise flicker across her face, and her hips stilled for a moment.

Caster thought she understood Shirou, but she was wrong. There was more to the act of making Nerve Circuits than an insane pain tolerance. It required an iron will and a stalwart master of the self. In truth, his mental fortitude might have been even higher than Saber's.

However, by the same token, Shirou didn't understand Caster either. If she wanted him to submit, a single spell would have had him kneeling at her feet obediently and unquestioningly. What she wanted was to break him. To make him admit his own defeat. And if he shattered that easily, what would even be the point of that?

"Well said," she replied. "Then let us play the game of pleasure and endurance, shall we?"

She started to move her hips again, this time in a smoother and faster fashion with no break between pulling and pushing. Shirou kept his mouth shut. The truth was that Caster's words had hit close to home.

He couldn't trust his voice. Previously it took all of his focus to talk back as he did. Now that the pain had become just intense discomfort, it was much more difficult to deal with the pleasure it was causing.

He hated it. He hated that this vile act which went against his sexuality felt good in any way. It wasn't surprising that feeling pleasure from this violation caused the heart of the victim to become muddled and for them to call into question their own worth.

Unlike him, Tohsaka and Saber were prideful people. It might have been impossible for them to reconcile their hearts with the betrayal of their bodies and it broke them. Their strength had been their weakness, but Shirou wasn't like them.

Even if she attacked his pride as a man, shattered it to pieces and walked all over it, he would never submit to her.

Those were his thoughts anyway. After a little while, it became difficult to think straight. The stimulation of that mysterious spot had started to send tremors across his member and precum was leaking from the tip.

Although Shirou was a teenager, he didn't spend too much time playing with himself. Sometimes it was necessary as it was a distraction, but as someone who had a deep-rooted self-loathing, he didn't indulge in pleasuring himself more than needed. To put it bluntly, he had always just rubbed one out as quickly as he could and then went on with his day. He didn't even have any pornographic material except for the magazines that Shinji had hidden at his place.

The point was that he never tried to figure out how long he could last. He was already in uncharted territory, and he could only bite the inside of his mouth to mitigate the feeling coursing through his lower regions.

On the upside, Caster's voice had also changed, and her breathing was underscored by faint sighs of pleasure. At the very least, this confrontation wasn't entirely one sided but he had no idea how they really squared against one another. Furthermore, she was the one setting the pace. He was in no position to fight back.

Not that he'd know how even if he could.

"Ahh… your ass is far better than I thought it would be, boy. You lack Saber's beauty or Rin's elegance, but your ass and mouth might actually be on par with them. Hmm… I can't take it anymore. I'm going all out."

Before he could start to wonder what all out meant, she pushed his head forward and with the assistance of the chains he was forced to bend at a ninety degree angle, while Caster firmly gripped his hips.

"Take this, you little slut," she moaned before starting to hammer away at his asshole with her cock.

Shirou's vision swan. Partly because of the sudden shift inside of him, but mostly because the pleasure had more than doubled. He caught himself in time to lock down on the pressure that jumped up inside his scrotum.

If previously Caster's cock was only brushing against that spot , now it was straight up hitting it with each thrust. With every impact against his ass, Shirou felt himself rapidly approaching the edge of his climax. He clenched his teeth and shook his head, trying to clear his mind, but it just felt so damn good.

"Ah. Ahhh…"

His eyes widened. That voice, just now. Those moans…

They came from his mouth.

"Ahaha! Finally! What a cute voice you have been hiding there, boy. I knew you'd like this. Now more! Moan for me more while I fuck your ass!"

She picked up the pace even further and the pressure inside of Shirou's balls went over the edge.

"Khnn ohhh!"

He would have tried to suppress his voice but every little bit of his concentration was used to hold back the explosion that was about to go off between his legs. He had already climaxed and was just holding back the real ejaculation through sheer force of will.

Caster's movement had also become frantic. The pillar of meat inside of Shirou's ass was throbbing not unlike his own much smaller one was doing, and he could feel Caster's own much hotter precum spilling out of her cock, making its movements inside him slicker. She too was on the edge of her climax.

At the very least in terms of endurance, they were evenly matched.

Unfortunately, even if they had somehow wound up head-to-head a step from the finishing line, one was a novice trying to keep up while being forced to endure everything and the other was a veteran setting the pace.

Just as he thought that he might make it, Caster put an arm under each of his legs and lifted him up, locking her hands behind his head. Then she started ramming her cock up into him from below while also forcing his body down to meet her hips, her meat reaching deeper and hitting harder than ever. With each thrust his fully rigid cock bounced up and down, causing strands of precum to be flung all over the place uncontrollably.

"Cum! Cum you little faggot! Cum for me!"

He tried. Oh, he tried more desperately than anything else not to do just that. He tried even though every fiber of his being was begging him to just let go. He tried his absolute hardest and he failed.

"Guh..uhhh. Kahhh!"

The dam broke, and the ejaculation that he had been holding back rushed out all at once. Held up in a shameful position, with a cock much bigger than his own fully sheathed inside his ass, Emiya Shirou shot his load without restraint.

Only then did he see them. He didn't know whether the Witch had waited to dispel the illusion that hid them until just now, or if it was meant to go down the moment the duel was over.

Tohsaka and Saber were there, staring at him.

They were standing mere feet from him, looking at him with matching expressions on their faces that he couldn't name. But they were looks that reinforced the way he already felt.

Worthless.

At that time, in that position, being looked at in such a way by the two people he respected the most, his mental fortitude was completely obliterated. And then, mere seconds after he had utterly and completely lost, Caster slammed her cock into his ass one last time and released her own, much more massive load inside of him.

The heat that coursed through his body, the pressure against the back of his dick and in his guts, the feeling of defeat in his heart. It was too much, and even though he was still cumming, another orgasm hit him, even more intense than the previous one.

"Kyaahh!" he moaned, eyes getting crossed.

Even though Caster was holding perfectly still as she unloaded her seed inside of him, Shirou's dick bounced up and down from the sheer force of his own ejaculation. It was as if it was cheering its own defeat and the humiliation of its owner, for that was how good it felt.

"Emiya-kun… no way."

Hearing Rin calling his name like that, the sheer disappointment in her voice when he was at the height of by far the greatest carnal pleasure he had ever experienced smashed his heart to pieces.

He had failed her, failed Saber and failed his own pride as a male. And throughout it all, through all the anguish and shame, he couldn't stop cumming to the giant cock in his ass, still painting his insides white with its own load.

Like a little, masochist faggot.

He was too far gone, far too crushed by pleasure and humiliation to even put his hands forward when the chains released him and Caster slid out of him, dropping him to the ground like a sack of bones.

He was still squirting his useless sperm as he laid face down with his ass up, while Caster's much thicker seed dribbled out of his ass in copious amounts. He was still far too out of it to notice the slight burning sensation taking place on his left buttock as the stylized drawing of a sword appeared on his skin in a deep, purple color.

He didn't know how long he laid there, cumming, but he was brought back to his senses when Saber and Rin's feet both touched the ground close to his head as they passed him by to make their way toward Caster.

Only then did he manage to right himself and turn around, only to see Caster sitting on a throne that hadn't been there before, with her legs spread and her cock still standing tall as a pillar. Rin and Saber stood in front of her with their backs turned on him.

"Toh… sa…ka… I'm…"

"That's enough, Emiya-kun," she said without turning. "You have done enough already."

Those might have been her words, but the tone of her voice told a different tale.

You are useless.

Even if she didn't say it, even if she didn't mean it at all… No, even if she denied it in earnest, those were Shirou's own thoughts.

Saber on the other hand didn't say a single thing. She was already past acknowledging his existence altogether. Perhaps it was already a mercy that she tolerated his presence at all after he had tried to kill the person she had pledged her body and heart to.

Without any instruction on Caster's part, Saber and Rin both kneeled in front of her cock and started worshiping it with their mouths, running their tongues all over its length. Shirou could barely see their expressions but they were certainly ones of utter adoration.

"I do believe that our duel is concluded," Caster said smugly. "So what will it be, boy? Do you still wish for your pathetically boring freedom , or are you willing to pledge yourself to me as my cock-sleeve? If you wish to stay, then crawl your way between them and put your mouth to work for me."

In spite of his crushing loss and the destruction of his fighting spirit, Shirou's reply came swiftly and without a trace of doubt.

" Never ."

Saber and Rin both stopped momentarily and briefly glanced at him with wide eyes. Even Caster appeared surprised.

"...Oh. Very well then. In that case, there is no more reason for you to remain here, boy. Begone. "

She snapped her fingers and a deep layer of darkness fell upon him, drowning his body and mind. The last image to be engraved in his brain was that of Rin and Saber intertwining their tongues around the tip of Caster's cock.

And then he knew no more.

The Dangers of a Witch's Staff

Chapter 03

"Aah!"

Shirou woke up with a start, drenched in sweat and gasping for breath. The sun was shining through the rice-paper doors to his room and the birds were chirping quietly just outside.

"Wh-What?"

He looked around, but everything was perfectly normal. Nothing was out of place or amiss. He was in his home. However, the last thing he remembered didn't match the current situation. He immediately got out of his futon and opened the door to the patio and the courtyard. even though he was just wearing a shirt and boxer briefs.

It was his house, precisely as he had left it. It was almost as if the events of the previous days were nothing more than a dream, but he knew them not to have been such. He still felt the echoes of what Caster had done to him.

He checked the house and found nothing amiss. Except that there was no trace of Tohsaka or Saber anywhere, even though they had both been staying at his place for quite some time. It was as if their passage had been erased completely.

He had no recollection of how he got there. Did Caster bring him there? No, it was more likely that she hypnotized him to come back on his own. She had completely dismissed him after defeating him on every front.

He felt humiliated from what she had done to him, but it all paled when compared to the memory of failing Saber and Tohsaka.

"You have done enough already."

He couldn't forget how dispassionate she sounded when Tohsaka said those words. He couldn't ignore how he felt when he realized they had seen him lose to Caster in such a fashion.

But none of that mattered. He was still alive and he could still fight. Caster had made a mistake letting him live.

He wanted nothing more but to march back to the church and face her again, but he had no idea how to beat her. Could he even use Magecraft anymore? Would Caster have unsealed his Circuits? The only way he had of finding out would be to try, but if he killed himself in the process he would waste whatever little opportunity he still had.

As much as he wanted to go out there and fight that Witch face to face, he had an obligation to swallow this impulse and come up with a plan. He clenched and unclenched his fist several times in a row, while he took slow and deep breaths.

It took a few minutes, but he did manage to calm himself a bit.

Tohsaka and Saber shouldn't be in any danger, or rather they had already suffered damage. Could he undo it? With the Grail he could. But could he steal the Grail from Caster? And more specifically, from Caster who had the Grail and Saber on her side?

He knew the chances of victory were non-existent. They were already slim when he had Tohsaka working with him. and now it was likely that she would fight against him like Saber had. Even so, there had to be a way. He couldn't resign himself to what had happened; he had to make it right even if it was the only thing he did with his life.

It would take the Grail to fix all this. Nothing short of that would do. And that meant taking it from Caster or getting his hands on another one. Kirei had said that there had been over seven hundred objects that met the description of "Holy Grail". It shouldn't be impossible to track down another one.

That was marginally less fanciful than beating Caster, Saber and Tohsaka on his own, but it was an extremely long term plan, and he couldn't bear the thought of leaving them in their current circumstances for a second longer than necessary. But to properly come up with a plan, the first thing he needed to do was assess the situation.

Feeling his stomach grumble, he decided to take care of his basic needs first. He made himself a hearty but simple breakfast and then he took a quick bath. He refused to acknowledge the trauma that Caster had inflicted on his body and mind, therefore he didn't check himself in the mirror for anything out of place.

Had he done so, he would have perhaps noticed a sword shaped mark, not unlike his old Command Seal, engraved on his left buttock. He got dressed and then marched out of the house, heading toward the Kotomine Church. It was late morning by the time he got there.

According to his calendar, it had been over two weeks since he came here last time with Lancer and Tohsaka to challenge Caster. It looked like nothing ever happened, but that was par for the course with Magecraft, let alone someone of Caster's skill and power. He didn't feel anything abnormal around the building, but he wasn't even sure he could still detect the supernatural the way he used to.

After checking the surroundings for a while, he gathered his courage and went to the door, pushing it open and walking right inside. The only thing that met him was the music of the pipe organ that was being played by a white haired figure.

She didn't pay him any attention and just continued playing. Not knowing her identity, Shirou decided it would be wise to wait until she reached the end of her tune. Only then did she pull away from the instrument and turn to face him.

"Emiya Shirou, I've been told to expect you."

Shirou immediately took a step back. Even though she was basically on the opposite end of the large room, he had no idea who this person was or why she knew his name.

"You don't need to fear me. I am not your enemy," she said.

"Who are you, then? How do you know my name?"

The nun approached slowly until she was standing a few steps away from him.

"My name is Caren Ortensia. I'm the new overseer sent from the Church to replace my predecessor after his untimely demise."

"Kotomine… is dead?" he asked.

"Indeed. It would appear that he broke his oath of neutrality and became a Master, taking part in the war."

"Wait, what? …Lancer! He was Lancer's Master."

"That would seem to be the case," she concurred. "Anyway, that's beside the point. You didn't come here to seek the counsel of the late Father Kotomine. Rather you have come looking for a Witch. She has already left this place."

He felt a chill go down his spine

"Where did she go?" he asked.

The thought hadn't crossed his mind before, but Caster would no longer be bound to Fuyuki. She could have departed for any place in the world and he'd have no way of finding her.

"To her stronghold atop the mountain, I would presume. She didn't exactly say."

He let out a sigh of relief.

"Did she tell you I'd be coming?"

"No, that was the Second Owner. She also left a message for you."

"What did she say?" he asked with his heart hammering in his chest.

"It's over. Stop struggling."

"Tha…that's it? There must be more than that."

"I'm afraid there isn't, and by your reaction it appears that you do not intend to heed her advice."

"Damn right I'm not going to."

"You understand that the Holy Grail War is concluded, right? And that Caster has won."

"You don't understand. I couldn't care less about any of that. I need to make things right."

"I won't pretend that I know what you are talking about, Emiya Shirou, but it's clear to me that you want to take Caster on as your opponent. Is that right?"

"What is it to you?" he asked.

"Whatever you wish to do, you need to understand that the Church will not get involved in any way."

"What do you mean? Isn't the Church supposed to control this land with the Second Owner? Are you saying you'll let me and Caster both run amok with no repercussions?"

"Yes, that's exactly what I mean, though more so for Caster than yourself. To be more specific, both the Church and the Clock Tower no longer have any authority here. Caster has declared this land as her domain."

"What? And everyone agreed to it?" he bellowed.

"No one sees any reason to challenge her claim. Trying to eliminate a Mage from the Age of Gods in possession of the Holy Grail who also commands a remarkably powerful Saber class Servant would require an extreme expenditure of lives and resources, and it has been ultimately decided it's not worth it."

"I can't believe this. They would just give up the entire city to her?"

"Ah. It seems there has been a misunderstanding. When I said this land, I didn't mean the city of Fuyuki."

"Then, what-"

"I meant the entirety of Japan."

Shirou's heart dropped down to his stomach. Caster managed to make the two most powerful mystical organizations in the world give up an entire country?

"How could they allow that?" he asked.

"You think it's too much to grant her?"

"You don't think it is?"

Caren shook her head.

"In truth she could have asked for far more. In the first place, the Clock Tower doesn't care too much about this region of the world. To them it's all just a backwater and its people little more than savages. As a Mage from the lost era, Caster is already held in higher esteem than all the people of this country put together."

"And the Church?"

"Even a third rate Mage with the Grail would have been regarded as dangerous as a Sorcerer. A woman of her caliber would require us to throw all of our forces and resources at her to have the slightest chance of winning, and even if we did win it would be a pyrrhic victory that would leave us crippled. The Church would thus be helpless to take any action against its actual rivals and enemies, so you can imagine why engaging in such a conflict with Caster is undesirable for us. As long as she's content with calling herself the Queen of this land and doesn't try to subvert the natural order too much , it's been deemed better to let her be."

"Even if that is the case, there's no way that the Church would accept giving her this much without getting something in return. What did she give in exchange for your superiors' cooperation?"

Caren shrugged.

"All they asked in exchange for the recognition of her authority is that she let one observer stay in Fuyuki since this city shares what seems to be the location of her main stronghold, and that she take care of any and every Dead Apostle that set foot on these isles. Not that any would be so foolish as to do so now, but it frees up our forces to hunt them down across the rest of the world."

Shirou leaned on one of the pews and sat down slowly.

It was worse than he thought. The two strongest organizations in the world had already sided with Caster. He couldn't turn to them for help, and he didn't possess the influence to sway them. He was stacked against even bigger odds than before.

"I'm sorry, but I couldn't let you leave without having full awareness of what you'd be going up against."

He waved off her concern.

"It's nothing you have to apologize for. I would have found out anyway sooner or later, and this saved me a lot of time."

Caren nodded tersely.

"Does that mean that even knowing this, you still intend to oppose her?"

"Nothing's changed. It's what I have to do. The odds in my favor were zero from the start."

"I see that you are a foolish man, Emiya Shirou," she sighed but then smiled faintly. "But I don't dislike that."

He nodded and got up, slowly making his way out of the church, but stopped before exiting.

"Thank you, Caren Ortensia."

"Think nothing of it. I am merely doing my duty helping another lost lamb, as is the Lord's will. I wish you the best of luck in your endeavors," she told him as the door closed behind him.

He headed home on foot. He needed some time to think. By the time he finally got there it was already almost noon. And he still hadn't found a single answer for the myriad of questions that he had.

He decided to clear his mind a bit and started cooking lunch. Working in the kitchen always put him at ease and this time was no different. Not that he wasn't still concerned, but it gave his mind a slight reprieve from this stressful situation.

He still knew how to cook perfectly well. He didn't need to ask himself how to do any of the required actions. It might have been stupid but it served to restore a bit of self-confidence within himself.

However, what he failed to realize until it was too late was that he had made enough food for three people out of habit. When he noticed, he grimaced. He was about to throw it all away in disgust when he heard the door open.

His heart leapt in his throat. He rushed out of the kitchen and ran to the entrance.

"Toh-"

"Ohayo, Shirou!" Taiga greeted, cheerfully. "What's for lunch?"

"Ah… Fuji-nee. It's you."

"Hm? Who else would it be? Were you expecting anyone?"

Shirou hesitated. Didn't she remember Tohsaka and Saber…?

'Her memories have been erased,' ' he realized.

Caster could probably do that and more without even moving from the temple.

"Shirou, what's wrong?" she asked.

"It's nothing," he replied, shaking his head.

"You look awfully pale. Are you sick?" she asked.

"I am feeling a bit under the weather," he admitted.

It was much worse than that, but admitting that much would probably get Taiga off his case after a little fussing.

Taiga put a hand on his forehead. Her hand was very hot to the touch.

"You are… your skin is very cold, Shirou," she said.

Shirou looked up at her and noticed that her eyes were shiny. Her face was also a bit red.

"It's you who's burning," he said, putting his own hand on her forehead. "Have you got a fever?"

Taiga pulled back, licking her lips several times as if they had been very dry.

"You know… now that you mention it I feel a bit light headed. It's probably just hunger though."

"Well, you got here just in time. The food is ready."

"Alright! I'm famished."

They went to the living room. Taiga sat at the table while Shirou took out the plates and served lunch. He turned on the television to fill the silence that would have inevitably lingered. He wasn't exactly in the mood to hold a conversation after all.

He sat at the table next to Taiga and they ate while watching the news. Nothing remarkable was said by the anchor. No strange incidents, no weird deaths, no serial killers. The Grail war was over and Fuyuki had gone back to the way it used to be.

Except that it was now ruled in secret by an omnipotent Witch, as was the rest of Japan.

Was this the curse that Caster mentioned putting on him? Could it be that he was unable to leave her territory? Was he bound to forever live in her domain, always under her power, unable to oppose her in any way? It would certainly be right up her alley, there was no doubt of that.

Had he not been so taken by his own thoughts, he might have noticed that Taiga wasn't eating as much as she normally did. He might have seen the glances he was getting from her, or the way she bit her lip and then furtively looked away every minute.

Instead he saw none of that, and after finishing his own meal he started putting the plates in the sink and began washing them.

"Thanks for the meal," said Taiga, getting up hastily while Shirou had his back turned. "I-I just recalled that I forgot something important back at school. I need to go back now."

"Eh? Sure," he said, barely glancing at her from behind his shoulders. "Are you sure you are feeling well?"

"Absolutely! Never felt better. Ahaha! G-gotta go now. Byeee!"

She quickly left the room. If Taiga didn't act weird nine times out of ten, he might have doubted her statement, but this being her he didn't even question it. Besides, he had more pressing things to think about.

He spent a few hours sitting on his patio, thinking over his options. Not that he had many. How was he supposed to fight someone who even the Clock Tower and the Holy Church didn't want to challenge? How many chances did he have, when even the most powerful organizations in the world had little?

None. Zero. The only thing he could get out of trying would be his own death.

And yet, even knowing that, he could not let go. He was the person who willingly pursued an unachievable dream from the start. This was just more of the same. It made no difference that he couldn't do it. He would do it anyway.

Having made up his mind, he got up and left the house. This time, his destination was Ryuudou Temple.

What would he do once he got there? He literally had no clue, but he had to see the situation with his own eyes. He wasn't told to stay away so he wasn't worried he'd be killed just for showing his face around. He was no threat to Caster and everyone knew it. She had let him live out of mockery, and that wouldn't change so easily.

He took the bus across the city, feeling apprehensive about what he might find there. With Caster's powers, she could have easily turned the place into a luxurious palace filled with marble and gold. When he got to the base of the mountain and started to climb the long, stone staircase he almost expected to be met by heavily armed and armored guards demanding to know what business he had in the Queen's palace.

None of that happened and he got to the top unchallenged. However, there was someone waiting for him at the gate.

"I knew you would come."

She stood with the sun at her back, wearing a white winter dress with gold patterns. With the light framing her golden hair, she looked absolutely radiant.

"Saber."

He wanted to approach her, but her body language was not welcoming. She was standing firmly in the middle of the gate, blocking his access. The message was loud and clear.

For a moment neither one of them spoke.

"I -"

"What do you think you can achieve by coming here?" she asked, cutting him off.

"What?"

"I know just how idealistic and stubborn you can be. Yet even you should understand that there is nothing more that you can do. Rather, there is nothing more that should be done. You can't change what's already happened."

"That's… quite hypocritical coming from you," he replied.

Saber tipped her head.

"So, you knew. Indeed. I am not someone who can cast judgment on others, least of all the person I betrayed. Nevertheless, you know that I'm speaking the truth. What do you seek here, Shirou?"

Indeed what did he want? What strategic advantage could he get from coming to the temple at this junction? There was none and the truth was much simpler.

"I wanted to see you and Tohsaka. I wanted to know how you were doing. Know that you were both okay."

Saber looked away.

"After what you have gone through, you should be thinking about yourself, not us."

"How are you, Saber? Is there… is there something I can do for you?"

"I would appreciate it if you stopped worrying about me," she replied tersely. "I'm fine, Shirou. I've never been better."

"What about Tohsaka? Can I see her?"

"Rin is no longer here, Shirou."

"What do you mean? Where is she?" he asked in alarm.

"I would suppose she went back to her place."

"Are you telling me that Caster let her go?"

"Why wouldn't she? Rin has already proven her loyalty to our Master. There is no reason why she shouldn't have her freedom whenever her service is not required."

"Yet you are still here."

Saber sighed, and her shoulders dropped.

"The truth should have been self-evident, but I should have known that you would have rejected even the painfully obvious,'' she said, looking down. "I will no longer sugar-coat my words around you."

"What do you mean?" he asked, brows furrowing.

Saber looked up and in Shirou's eyes. Her gaze was hard and unwavering.

"I am still here because this is where I belong, Shirou. It's where I want to be. I chose Caster over you in every way. It is a decision that I made knowingly and willingly, and while I didn't intend to cause you any misery, it is not a choice I regret making. In fact, it's a choice I would make over and over again, even knowing how it would affect you."

Shirou felt the air being driven from his lungs almost as if Saber had physically punched him in the guts with all of her strength as a Servant. It was one thing to think she succumbed to Caster's vile methods, and another to hear her say that it was a choice she would make again despite knowing the consequences.

He was speechless. He couldn't utter even a single word in response.

"If you finally understand, go back home and never come back. Leave your old life and all of us behind you and find what happiness you can while living a normal existence. Caster has shown you great mercy, you would do well not to waste it. If you keep on struggling, you and only you will suffer as you reap the consequences of your futility."

Shirou gritted his teeth and clenched his fists. He suppressed the stinging sensation behind his eyes.

"You have made your choice, Saber," he replied. "And I have made mine."

He turned around and made to leave.

"Shirou," she called out and he looked at her from behind his shoulder.

"This should go without saying, but Rin has made the same choice as I did. Don't bother anyone with your delusions any longer. Our relationships are already a thing of the past."

"Tch!"

He scoffed and walked down the stairs. He couldn't put in words the bitter feeling in his chest, but it was like someone had ripped his heart out of his ribcage and stomped all over it until only paste was left.

'It doesn't matter. Once I have the Grail, everything will go back to normal. To how it should be.'

Far from being dissuaded, Shirou found his resolve strengthened. Pain never deterred him from doing anything, and in fact it served to give him even greater focus. He wasn't the kind of man that could be scared away by threats of harm or death. As long as he believed that he was on the correct course of action, he would keep moving forward no matter the obstacles in his path.

He took a taxi back to the residential area, straight to Tohsaka's place.

He got out of the taxi and waited for it to leave before he rang the doorbell. There was no response. He rang again and again, with no avail. He didn't think that Saber would have lied over something like this, especially considering that Rin had left a message for him with the church overseer.

She just didn't want to see him. She didn't even want to talk to him.

Well, it wasn't like he needed to hear from her the same things he already heard from Saber.

"TOHSAKA!" he shouted. "I'M NEVER GIVING UP!"

There was movement from one of the curtains on the second floor, but he didn't see anyone. Trusting that his message had been received he turned around and headed back home, on foot once more.

One way or another, the fight was on.

The Dangers of a Witch's Staff

Chapter 04

By the time Shirou got home it was already getting dark. The house was silent and all the lights were off. It felt every little bit as cold and empty as he felt inside. The situation was hopeless, and the only thing that kept him from giving up was his absolute stubbornness.

What recourse did he have when he was so hopelessly outmatched? No matter how much he thought about it, he couldn't find a single way out of this mess. But he was also the kind of person that would throw himself against a wall endlessly if he had to, even if it would only shatter his body.

He was unable to stop trying.

…He still had something that he could try, even though it might wind up killing him. He had to try to do Magecraft. He had no idea if Caster had unsealed his Circuits. He couldn't see any reason why she would, and also no reason why she wouldn't. He wasn't someone who could threaten her, after all.

Worst came to worst, he would die. Either way he couldn't just pass on it if it presented some sort of chance, and if they were sealed by someone of Caster's caliber no one alive would be able to undo it. That was the sad truth of the situation. His very first move would put his life on the line.

It couldn't be any other way. To be a Magus is to walk with death. If he let fear of dying to Magecraft rule his actions, he already was no longer a mage.

With that in mind, he went to the toolshed that had served as his Workshop for many years.

He made sure to lock the door behind him. If the attempt went horribly wrong, at least Taiga wouldn't stumble upon his mangled corpse. Eventually, if he died, she would come looking for him and finding him nowhere she would have to get someone to break into the shed.

He hoped that whatever poor fellow found his remains would keep Taiga from seeing them too. It was the best he could do with what he had available.

He sat seiza on the ground for a few minutes, taking deep breaths to center himself, emptying his mind of all foreign thoughts and emotions. Then he pictured the hammer of a gun pointed at his head being cocked back and then he pulled the trigger.

"Trace On."

The hammer went down and the metaphysical gun fired a bullet in his head, activating the Circuits inside his soul. He felt the familiar searing heat course through him. It was an uncomfortable feeling as ever, but his head didn't immediately explode so that was good.

He was two seconds into this process that he started to believe Caster had laid no trap for him.

He felt the heat increase becoming almost unbearable, but before he could close his Circuits it all flowed down his body, to a particular spot at the base of his spine, where it hit him like a sledgehammer.

"GHAAAA!"

His back arched reflexively as his prostate received the brunt of his magical energy. It was impossible to resist that level of stimulation. His body acted according to its functions reinforced by the onslaught of Mana, and violently released all of his seed at the same time.

Squirt! Squirt! Squirt! Squirt! Squirt! Squirt! Squirt!

His body just wouldn't stop ejaculating. It was so sudden and violent that his dick couldn't even get hard. And more importantly he was shooting far more semen than he knew his body normally held. He was young and healthy, but he just didn't have all that juice inside of him.

"Khhh!"

It was inhumanly hard to simply stay conscious through the ordeal of a seemingly never ending climax. He had no idea how much time passed while he tried to keep his mind from shattering under the pleasure, but it felt like years.

Eventually, the effect subsided; his body gave in and he slumped to the ground in a wet splat. His clothes were soaked with his semen and it had seeped through onto the ground under him.

For several minutes he could do nothing but lay in a pool of his own fluids breathing heavily and barely clinging to consciousness.

He should have known better than to think any trap of hers would have been something straightforwardly lethal. After all, if she wanted him dead she'd already had every opportunity to kill him. Instead she repaid defiance with humiliation time and time again. She even broke Saber and Rin that way. Why would she act any differently with him?

He clenched his fist in rage. If she thought this would stop him, she was dead wrong. Caster didn't understand that no amount of punishment or humiliation wrought upon him would deter him in the slightest.

However, if this was what would happen every time he used his Circuits, it was going to be a huge problem. It was kind of difficult to do Magecraft even during a regular orgasm, much less one that lasted for minutes.

After a little bit, he picked himself up from the ground and removed his clothes. Then he made a beeline for the bathroom to clean himself up. The experiment had taken more time than he had imagined and Taiga would soon come over for dinner. He had to clean and compose himself so he could get started on that.

[br]

About twenty minutes later Shirou was done cleaning up. He would take care of the mess inside the shed later. In the meantime he realized that in his hurry he didn't bother getting clean clothes. So he put a towel around his waist and got out of the bathroom.

"Oh!"

He found himself face to face with Taiga. He hadn't heard her come in, so he was surprised when he found her right outside of the bathroom door. For a moment they stared at each other wide eyed.

"Oh… hi Fuji-nee," he said. "Sorry, I forgot to take my clothes with me before taking a bath. I'll go get dressed and get started on dinner right away."

Taiga didn't reply immediately. Her eyes were looking at him from head to toe and back again. Her face was an intense shade of red and her breathing was labored.

"Taiga, are you feeling alright?" he asked worriedly.

"I… I'm…"

Even though he was half naked, Shirou immediately forgot about that and quickly put a hand over her forehead.

"You are burning up. Do you have a fever? Come lay down," he said.

Without hesitation he strong-armed her to his room, where his futon was already laid out from the morning.

"Shirou… I'm… I don't need… I'm fine."

"Nonsense. You are going to lay down and rest," he insisted. "And then I'm going to make you a chicken broth that you'll drink without complaints. Here, change into this."

He handed her a clean set of pajamas.

"Shirou… I don't…" she objected weakly.

"I'll strip you myself if I have to," he warned.

"A… alright," she conceded.

Shirou nodded, grabbed a set of clean clothes for himself and left the room to Taiga so that she could get changed. He momentarily put aside his quest to defeat Caster and focused entirely on the person needing help in front of him.

He got dressed, went to the kitchen and immediately started working on dinner. His hands moved expertly across the counter and in a matter of minutes he whipped together a meal perfect for a sick person.

He put everything on a tray and walked back to his room like a man on a mission.

"Taiga, dinner is rea-"

He opened the door and froze on the spot. Two pairs of eyes were locked together like deers in the headlights. Taiga hadn't changed into her pajamas yet. In fact she had yet to remove any of her clothes aside from her pants being around her knees. It appeared that she'd lost track of time doing something else .

She sat on the ground, holding Shirou's used boxers from last night to her face, while her other hand had slipped between her legs. That image alone would have been enough to petrify them both in regular circumstances, yet somehow that wasn't the worst of it. Far from it.

What shook Shirou to his core was the long, thick, veiny thing between her legs that she was stroking furiously and tightly with her slender, feminine fingers.

He was too stunned to speak, but the same couldn't be said about Taiga.

"Shi… Shirou… I… I… hnn! "

It was impossible to say what brought her over the edge. If he had just arrived upon her precisely at the last moment, or if it was something about his presence that tipped her over. What mattered was that right there and then she shot several ropes of cum all over his futon and the pajamas he'd offered her. It wasn't a small amount either. She could have easily filled a mug with that much fluid.

Still, he couldn't move or talk, or even just breathe. Part of his consciousness registered that he had dropped the tray and that the food he had prepared had spilled all over the floor.

"I'm sorry… I'm sorry," Taiga said apologetically, still holding his boxers to her face and still stroking her huge cock. "I didn't mean to make a mess. I just couldn't hold myself back any longer. Please forgive me."

Wait… that was what she was hung up about, and not the completely extraneous appendage sticking out from between her legs, or the fact that she was jerking off to his used underwear?

'She doesn't know.'

To her mind there was nothing wrong with her body or feelings. She was still openly stroking herself even though he was right there, looking at her.

"I love you so much, Shirou. I want you so much. I know I'm much older than you and your guardian, but I want to be with you sooo much. Please…"

"T-Taiga…"

"Please… will you let me fuck you?"

"Eh?"

"I need it so badly, Shirou. I've tried masturbating but it's just not enough. My cock is aching to slide inside your tight asshole and fill it up with my cum. I need to bend you over and fuck you in your ass. Just once… m-maybe twice? A-And maybe after… you could suck my cock? …T-To clean it. And also get a proper taste of my cum."

He took a step back. Taiga was making no overt moves, still sitting on the ground stroking herself while she stared at him pleadingly and lustfully.

It was too much. He could no longer stay there. He didn't know what would happen if he did and he could not hurt Taiga no matter what she did.

He fled. Without a single word he ran off. He didn't even close the door after himself as he left the house.

But he wasn't just running away. He was not scared. He was pissed as hell. There was only one person who could be responsible for this situation and she had messed with the one person she should never have. His rationale flew right out the window. It no longer mattered that he was running to his death. He had to go there. He had to make her pay for her crime and god have mercy on anyone who got in his way.

His feet carried him all the way there. He paid no mind to his burning lungs and muscles. Time ceased to have any meaning right until he stood once more in front of the temple's gate and its guardian stood in his way.

"What have you come here for?" Saber asked.

"Get out of my way," he said. "I'm here to kill Caster."

"Have you completely lost your mind?" she asked. "You wouldn't stand a chance against her even if I let you go through, which will only happen over my dead body."

"Suit yourself;" he said. "Trace On!"

The Circuits opened and Mana flooded his body. Just like before, it all rushed down that part of his anatomy.

He didn't feel anything. His rage had already surpassed any kind of earthly pleasure. The Married Blades manifested in his hands as easily as breathing.

"She shouldn't have touched Taiga," he said. "If you try to stop me I'll kill you and everyone else who stands between me and her. I don't care who it is. I won't let anyone get in my way."

Saber looked completely shocked. Just a few hours earlier, he had come looking for her, full of worry for her safety. Now he was threatening to kill her and was absolutely serious about it. He didn't look the least bit hesitant about it either.

She shouldn't have been surprised, though. The reason why things had ever gone this way in the first place was because Caster had previously taken Taiga hostage and bartered her safety in exchange for Saber.

"I see," she simply said. "It cannot be any other way."

Excalibur appeared in her hands, already fully unsheathed. Although there was something akin to a sorrowful look on her face, her loyalty to Caster was unshakable. She knew that Shirou would not stop unless she killed him, not after Taiga's wellbeing had come into question. There were just some things a man couldn't let stand.

He took a step toward her and she prepared to strike him down. A single swing would be enough. They both knew it.

"Hold it, Saber!"

Caster's voice rang out from everywhere at the same time.

"Master?"

"Let the boy through. I will listen to his complaints."

Even Shirou was surprised enough that he temporarily snapped out of his rage.

"But, Master… he will certainly try to kill you!"

"He doesn't have the ability to do so. There is no need for you to worry. Take him to me."

"As you wish," she replied.

Saber turned and Excalibur dematerialized. Then she started to walk in the direction of the temple. There was no need to tell Shirou to follow her. He did so of his own volition, Married Blades still held tight in a white-knuckle grip.

She led him into a building and the moment they both walked through the doors, they slammed shut and the room was dropped into pitch black darkness.

"Show yourself, Caster," Shirou called out, unafraid.

"My, my, you really still have yet to learn any-"

The moment her figure appeared, Shirou threw one of his blades at her, but it went right through her as if she was immaterial.

"-manners. Really, did you think for a second it would be that easy?"

Excalibur was once more in Saber's hands and she had turned back to him, blade raised.

"None of that, dear. Though I do appreciate the concern. Like I said, he's unable to harm me."

"You might as well not bother if you are only going to show me illusions," said Shirou.

"I'm no illusion, boy. I'm fully here in the flesh. I have merely ascended to a higher state of existence since we last saw each other. Meager things like Noble Phantasms can no longer scratch me, let alone your Projected copies. Only a wielder of True Magic would have any hope of matching me, and you are the farthest thing from that, short of being just a regular human."

"...Undo what you did to Taiga, now ," he demanded.

"Sure thing," she replied, snapping her fingers. "It's done."

Shirou looked momentarily surprised.

"You are lying," he said.

"Still with the baseless accusations, I see. I did not lie, boy, although it is true that I deceived you. I didn't undo anything because I didn't do anything. If you want to speak with the person responsible for your surrogate sister's situation, you should go look in a mirror."

"What kind of crap are you saying? I didn't do anything to her."

"Of course you did. Did you already forget our wager? I told you that in the event you lost to me, I would place a curse on you. This is merely the result of your inability to back up your claims, and now you must face the consequences."

"She had nothing to do with that!" he shouted. "I never agreed to let you harm her!"

"It seems I must reiterate that I didn't do a single thing to her, much less harm her."

"Well if not you, then who?" he asked.

"I already said it once: you did. Don't you understand? You agreed to let me put a curse on you without even asking what it would do, and this is the result. Do not blame me for accepting the terms before I even had a chance to explain them. From now on, all the women in your proximity who hold feelings of affection for you will grow a dick, a large one at that, and will feel a strong urge to have sex with you whenever they see you. But unless they know about the curse itself, they won't even realize anything's out of the ordinary, nor will anyone else who might witness the results. They are perfectly fine for all intents and purposes. You are the person responsible for this situation, and the only person who actually suffers from it. Yes, for the rest of your life the only women who'll love you will be certain to have a dick much bigger than your own and feel the urge to use your body to satisfy their lust. I advise that you get used to it, sooner rather than later."

"Undo it!" he said.

"Oh, why would I do that?" she asked.

"Because it's wrong! You had no right to mess with Taiga like this!"

"Still trying to put the blame on me, I see. If you had just admitted defeat when it was time, none of this would have happened. I would have let you walk out and go back to an ordinary life. You may not have understood what you were getting yourself into, but that doesn't change the fact that you agreed to the terms I presented. This is the consequence of trying to play the hero when you don't have the requirements."

Shirou gritted his teeth. Although he didn't buy anything she said, it was true that if he had just yielded, things wouldn't have devolved to this point. The curse was sick and cruel, but it wouldn't exist if he hadn't challenged Caster to a contest he'd fully known would be all but impossible for him to win. The guilt tore at him.

"If I use Rule Breaker…"

"Ah, yes. That old trinket. That would certainly break the curse although it wouldn't revert the changes already made to other people. It would at least stop it from affecting anyone else though, so why don't you go ahead and do it now? What's keeping you? Project my dagger and stab yourself right in the butt if you think that'll help."

Shirou frowned. Why didn't he think about that before? Because he was too enraged? No, that wasn't it.

"You didn't think I'd make it so easy, did you? Rule Breaker is an Anti-Magecraft Noble Phantasm. A bane to all Mages, even myself. It's not enough to threaten me now that I have the Grail, but it would have been a nuisance leaving you with it. I had already completely erased any knowledge of it from your mind before you awoke and we had our fun little wager."

"Kh! You have really thought of everything, haven't you?"

"For the most part, yes. But I must admit, possessing unlimited power is a little bit boring when no one else even comes close, so I will play with you a bit longer; especially since you are so adamant about getting in my face. To that end, I'll make another deal with you."

"What kind of deal?" he asked warily.

"I won't reverse the curse, but I will teach you how to do so yourself. Of course it will take you several decades at the least to learn enough Magecraft from me to get to such a point. In all likelihood you will never manage it during your lifetime given your current level of skill, or lack thereof."

"...Are you saying you are going to teach me Magecraft? You ?"

"I believe I made myself quite clear. Are you perhaps hard of hearing, or just that slow?"

"What's the catch?" he asked, knowing it was too good to be true.

"It's quite simple really. Any time you come up here to receive lessons from me, you'll have to pay a toll to the person watching the gate."

Naturally, there was just one person fitting the description. Shirou's eyes turned to Saber.

"Master?" she asked.

"Consider this a boon, dear Saber. I know you have been struggling to keep my gift in check on your lonesome. This is your opportunity to finally enjoy it as it was meant to be."

"What are you talking about?" Shirou asked.

"Show the boy, Saber. Let him know what he must submit to if he wants to get what he seeks."

"Master… I would rather not-"

"That was an order, Saber," she said sternly.

"...Yes, Master," Saber agreed demurely.

She turned to Shirou before grabbing the hem of her skirt and lifting it high enough to reveal her crotch, and more importantly, the eleven inches long pillar of throbbing flesh sticking out of her white panties. It was hard and covered in angry veins, leaking arousal from the tip.

"Not you too, Saber," Shirou groaned while Caster made Saber's dress and panties disappear with a wave of her hand, leaving her in just shoes and a garter belt with stockings.

"Don't get so full of yourself, boy. This is not the result of the curse; lest you forget Saber still has her Magic Resistance. This is a gift I gave her as a reward for her loyal service to me, which she has been enjoying extensively in her free time whenever she is alone. I was actually just about to inform you of this when you so rudely tried to assassinate me, but that is neither here nor there. In any event, she has been enjoying this gift of mine quite a lot. Isn't that right, Saber?"

"Yes, Master," Saber replied, red in the face.

"No need to be embarrassed, Saber. I myself know all too well the joys of having a massive cock, but my own pleasure can wait. I did not give such a large cock to you so that you might only play with yourself in your room alone. You are still too much of a knight to use it on someone else and I will certainly not let you use it on me. Hierarchy must be maintained, after all. From now on, whenever the boy comes here looking for my guidance, he must serve your cock until you are sated in full. Such is my offer. He must either take it or leave it, here and now. So what shall it be, boy? Will you accept the hole you've dug for yourself and let your precious sister-figure stew in her situation, or will you degrade yourself yet again and become our dear Saber's onahole for the foreseeable future? Decide right this moment; either leave and never return, or serve her cock until it is utterly flaccid."

Shirou glared at Caster. He wanted nothing more than to carve her heart out, but it was evident that such a task was impossible for him no matter how hard or often he slammed his head against that brick wall. Even if he did kill her, there was no guarantee that it would do anything to help Taiga. No, what he needed was still the Grail, the plan hadn't changed. The stakes had just gotten so much higher, and while this was yet another soul crushing humiliation he would do what he had to.

He opened this hand, dismissing his remaining sword which disappeared before it could hit the ground.

"I accept," he said.

"Oho!"

"Shirou?" Saber gasped in a high pitched voice, briefly looking like the damsel she very much wasn't anymore.

"I told you, I won't let anyone get in my way, not even myself. Have your way with me however you want to," he said, crossing his arms over his chest.

"I… I don't… I mean…"

In stark contrast to Taiga, Saber didn't exactly seem too eager about having sex with Shirou. Although the frantic throbbing of her cock showed that it was more out of embarrassment than anything, and the desire was very much there.

"Hm, this just won't do. But if Saber doesn't want to participate, I guess the deal is off the table. If your tight little holes don't drain every bit of cum from her cock then I'm afraid this won't go anywhere," Caster said amusedly.

"I understand, I'll do it myself," said Shirou resolutely, stepping toward Saber.

"Eh?" Saber and Caster said at the same time.

"Let's not waste any time."

He had left the house without even putting on a jacket. Heck he didn't even put on shoes. He immediately took off his shirt.

"Shirou, you…"

"You think I care? I let that Witch do the same thing to me for you and Rin. I would do this a thousand times over for Taiga."

His voice didn't waver in the slightest. Was he happy with this? No, he hated it, but in his twisted mentality he preferred this happened to himself over any other person getting hurt, let alone someone he loved. His body had already been defiled once. What did it matter how many other times it would happen again? Not at all.

He reached out and without hesitation he grabbed Saber's new meat sword.

"Ah!" she yelped, but made no attempt whatsoever at pulling back.

Shirou started to stroke her, even though he was having a difficult time managing her massive size, especially from that angle. His experience in handling a dick was from the perspective of being closer to the base, not the tip.

Then he just had to change that, didn't he?

He reversed his grip on her shaft and at the same time moved behind her, wrapping both arms around her and grabbing her appendage with both hands.

"Eh? Ah? Hnn!"

From this position, he had a better angle he was more familiar with and thus a bit more experience. Less than the average teen male, probably, but surely still more than Saber did.

There was a sick irony in the knowledge that he would have never had the courage to hold her this way so readily back when they were on the same side. Only now that they were on opposite ends of this diatribe did he have no hesitation in embracing her intimately.

It was all wrong, and he had to go through with it anyway.

He couldn't even hate her, not really. It was him who gave her away to Caster in exchange for Taiga's safety. If anything he betrayed her first. There was more truth to Caster's words than he wished to admit. Perhaps he was just as guilty of this outcome as she was, if not more.

He could easily make a list of all the times he went wrong.

He should have been humbler and not have taken Caster's bet.

He should have been better and not have let Caster take Taiga hostage.

He should have been wiser and left Saber to another Master, that first night at the church.

He should have just dropped dead with everyone else on that fateful night ten years before.

In the end everything came back to him. He was guilty from the very start. He chose to be part of the Grail War because he wanted to be a hero, and in the end he'd proven unworthy. Therefore this was his burden to bear no matter how twisted and humiliating it felt. Caster was equally to blame, certainly. Unlike him she was forced into the Grail War, but her actions were similarly her own.

She would pay her due, in time. Now though… now it was his turn.

He moved his hands up and down Saber's shaft with the fluidity of someone who had done it too many times to count. He might not have done it regularly, but there were thousands of days in the life of a teenager. There had been plenty of occasions to learn the ropes, even with only sporadic exercise. Even by doing it sporadically, he still had done it at least a hundred times. He knew what he was doing.

"Hmm… ahhh!" Saber moaned, knees slightly buckling.

"Fufufu! As expected from a boy whose dick has only ever known the touch of his own hand. Your wrist technique is quite polished," Caster teased. "But I was very precise with my words, boy. You must use your holes to uphold your half of the deal. I will not accept anything else."

"Tch. I understand, already," he scoffed.

He let go of Saber's cock, putting both his hands on her shoulders and forcing her to turn around, seeing that she'd been keeping her eyes closed through all of this, but that didn't matter to him. Then, without a single word he dropped to his knees, eyes level with her shaft. He had been through this before so he already knew what had to be done. He opened his mouth and let his tongue out, pressing the tip of Saber's manhood against it. The salty taste of her oozing precum filled his mouth.

"Ahh… Shirou…"

He paid no mind to her moans, focusing instead of licking the length of her massive dong and coating it with saliva as much as he could.

"Oh, your tongue work is still as rough as the last time, but you are also just as passionate as ever," Caster commented. "You really are a born cocksucker."

Just like when he did this to her, Shirou didn't deign to give the Witch a response. Anything he said she would twist against him and he wasn't keen on giving her that pleasure. Instead he put the tip of Saber's cock into his mouth and started sucking on it the same way he had done with Caster's previously.

"Ohhh!" Saber moaned, as she placed both her hands on his head and pushed her cock into his throat, and all Shirou could do was accept it.

"Grrrk!!"

That was the only sound that could escape his throat as it was packed full of hard meat.

"See Saber? No hesitation at all. He just started sucking on it without needing to be told, and now he's letting you stuff his throat without complaint. He's never been with a girl before even though he likes them, but this is already the second dick he's sucking. That we know of, at least. Personally I think he's doing this a bit too eagerly not to have sucked at least a few cocks in the past."

That comment seemed to be a tipping point for Saber, because she started to move her hips back and forth. At first it looked as if she was trying to hold herself back, but with each thrust she got more and more into it.

"So warm… so warm, and wet and tight!" she groaned. "I had no idea having my cock sucked would feel so good!"

"Do you finally see what you were missing out on, my dear? It's such a shame to have a cock and not use it as it's meant to be used, let alone ones as massive as ours. It's simply disgraceful for a man who doesn't even have the excuse of being homosexual to have sucked more cocks than the number of women he's laid with. Don't you agree, Saber?"

"Yes! Yes! It's so good. What kind of man wouldn't want to stick his cock into a tight warm hole when it feels this good?"

"A worthless man who would rather worship cock than use his own. Then again I suppose that's just one more thing that separates men from boys. Especially a boy who's a cock-loving faggot like your former Master here. Don't you think that's a perfect definition for little Shirou?"

While he ignored her taunts, Shirou continued to work Saber's shaft, taking more and more of its length into his mouth. It was only when Caster directly asked Saber that last question that she finally opened her eyes and looked down at her former Master to see him gobbling her cock.

"...Yes, he really is worthless as a man," she replied lustfully as she plowed his face and throat. "He couldn't help me, he couldn't help Rin and in the end he caused grief to Taiga as well. Maybe this is the only thing he's good for. Worshiping cocks so much bigger than his own."

It hurt, and not just physically. Coming from Saber it hurt a million times worse than anything Caster ever did or said.

"Go ahead and enjoy yourself, Saber. He might not be willing to admit it yet, but I'm certain he loves pleasing your cock just as much as you love receiving it, if not more. You already saw for yourself how much the boy enjoys getting his ass plowed, so definitely don't be afraid to hold back there. But remember, he can't receive guidance from me until you are done with him. So be sure to take full advantage of this opportunity, and use his holes to your heart's content. Teach him his rightful place in the world."

"Ahh… yes! I'll make him understand, Master," she promised as he held his head tighter and increased the pace of her thrusts. "Thank you so much for letting me do this. I'll make him admit that he's a cock-loving faggot who should not be playing hero. I'll make him realize that being a cocksleeve is all he'll ever amount to."

Caster clapped her hands a few times.

"That's the spirit, Saber. When you are done with him, send him my way. Provided that he still wants to learn Magecraft and not just get his holes pounded by me. Actually, send him my way in that case too," she grinned, before vanishing within the darkness from whence she came.

Saber saw this as her cue to truly enjoy herself.

"Ahh! Ohh! Hmm!"

All sorts of moans came from her throat the moment Caster vanished. It seemed that she had been embarrassed to really show how much fun she was having around her Master, perhaps out of fear of being judged. She didn't have such problems around Shirou.

Not anymore, at least.

He was no longer someone she cared to leave with a good image of herself. She just used him at her own pace, barely giving him a window of time to breathe and not suffocate, but even with that he was barely hanging onto consciousness.

"Ahhh… I'm almost there, Shirou. Just a little while longer and I'll- HMMM!"

Her cock was halfway out when her climax hit her, and her cum shot out in thick, hot ropes right at the entrance of his throat, burning its way down into his stomach. He nearly gagged, but Saber slammed the entirety of her cock inside of his mouth until his nose was pressed against her smooth abdomen.

"Mrgh!!"

She forced him to stay in place while she deposited the rest of her cum inside him.

'At this rate… I'm going to… pass out.'

Either sensing his precarious state, or maybe having just finished shooting her load, Saber pulled her cock out of him, allowing him to breathe once more.

He gasped for air and started coughing immediately after.

"Cough! Cough! Saber… Cough… you…"

"Do forgive me, Shirou. I admit I got carried away with my task," she said, sounding just barely remorseful. "But even so you took it without much trouble. My Master was right about your nature. You were born for this. For taking cocks. Big ones. Hmm… I wonder if having Avalon inside of you for so many years has turned you into a natural sheath? Such a powerful artifact must have had a great influence on you. It would help to explain why you have such a natural disposition for having long and hard things shoved into you and they end up being a perfect fit."

"What… cough… the hell are you… cough… rambling about?"

"Oh? I see there is still a lot of work to be done. Stubborness is truly the one thing you have in too great abundance. I shall endeavor to stomp it out of you so you can accept your true purpose. Drop your trousers, Shirou, now. I want to try out your other hole. I want to find out for myself which end feels better to have wrapped around my cock."

Shirou hardened his heart as he heard the command. This was both his choice and his punishment, and only the first of what he knew would be many such occurrences with Saber alone. He couldn't let it affect him and there was no point struggling against something he'd already resigned himself to. He got back to his feet and undid his belt, allowing his trousers and boxers to drop and expose his bottom half before he stepped out of them, leaving him completely naked.

His dick was obviously flaccid, and the humiliation he experienced had made it shrink even more than normal, as if it was hiding itself. Saber paid it no attention whatsoever, as she had no interest in that part of his anatomy.

"Turn around and get on all fours," she ordered, gently stroking her still hard cock expectantly.

Without looking her in the eyes, Shirou did as he'd been instructed and dropped onto his hands and knees. A moment later he felt Saber's hands grab his naked buttocks, caressing his rear muscles as if she was inspecting a horse. He felt her push his cheeks aside, revealing his defenseless asshole. Immediately after he felt something wet drip on his skin and turned his head to see that Saber had stuck out her tongue and was drooling saliva onto his crack.

Then she slid one finger inside his now well-lubricated butthole.

"Kh!" he groaned.

"This is a technique that my Master used on me, to help prepare my body," she said after closing her mouth. "I would encourage you to learn it yourself, but someone like you will never need to use it. Simply be grateful that even now you are receiving her undeserved grace."

She moved her finger in and out, just enough to get him used to what would come next. Unfortunately, the rage that had previously shielded him from the response of his anatomy had since subsided to manageable levels, and no longer afforded him any protection from the pleasures of his prostate.

Having that weak spot stimulated, his previously flaccid cock started to stir and grow erect. He wished he could control and suppress the physical feelings caused by having his asshole invaded like that, but he didn't have that kind of ability. He was once again forced to enjoy the humiliation against his wishes.

He had seen first hand how such a thing could mess with someone's head. Prideful as they were, both Saber and Rin had to have strongly denied that it affected them until they no longer could, and it broke them, leaving only Caster and the pleasure she gave them as the center of their world.

"Oh? Just this much is enough to arouse you?" Saber asked, having noticed the change. "It seems your body already knows its purpose and it's much more honest than you are."

Once again her words cut deep. Shirou wasn't prideful yet Saber was still someone he treasured, even though the betrayal ran deep in both directions. Also, he had learned a few things from Rin's and Saber's mistakes. He had chosen this route of his own volition, sacrificing his pride as a man, perhaps the only kind of pride he had left. There was no point then in lying to himself about the pleasure he experienced from this. It didn't change who he was or what he had to do. He would embrace every ounce of pleasure and humiliation wrought onto him until he reached his goal.

But he would never give Caster the satisfaction of letting her know that. He would keep dismissing her attitude as nonsense to his dying breath.

"You… certainly… have gotten talkative… Saber," he groaned out. "Which one… of us… are you trying… to convince exactly?"

The taunt was a shot in the dark. He had no way of knowing with certainty if Saber was already over what she did in the service of Caster, but part of him felt that she was trying to justify her own behavior by bringing him down to the same level as herself and below.

It seemed that he had struck a nerve, because Saber's hand stilled, and there was a long moment of silence following his accusation.

"…Still defiant, I see. I shouldn't be surprised. Words never held much meaning with you. I shall let the facts speak for themselves."

Having said that, she pulled out her finger. A second later he felt something much bigger pressing against his back entrance. He knew what was coming.

Saber pushed her cock into the opening of his ass, stretching him out bit by bit until the crown finally managed to pop inside.

"Hm!" Saber groaned, while he managed to not make a sound.

Slowly she pushed more of her length inside of him, causing him to feel his organs shift to accommodate its passage. With each inch of flesh pushing into his body, Saber's breath became more labored

It was uncomfortably big, but Shirou had endured worse than this from Caster already. The discomfort was the least of his problems, though. It was the intense rubbing and pressure against his prostate that gave him the most trouble by far.

Why the hell did the male body have to be built like that?

At last Saber managed to bury the entirety of her length into his backside, and held it there while breathing almost frantically. Evidently, she'd been stunned by the sensation she was receiving through Caster's gift being sheathed inside his ass.

Shirou could feel her heartbeat resonate through his body from there, and his own heart seemed to fall in sync with it. Her excitement was palpable and it was spreading through him against his wishes.

His cock had now reached its peak erection at a mere six inches and was shamelessly dripping his arousal onto the ground, throbbing in rhythm with their shared heartbeats. His own breathing was getting more labored just as he was starting to wonder why Saber wasn't doing anything.

"Ahh… Ahh… Amazing … Your ass is amazing, Shirou. It's so much better than your throat. I… I have to…"

She pulled back and started to move her hips back and forth, but in a few thrust she was already going as fast as she could.

"God! Oh, God! Shirou!!! It feels so good . Can you feel it too?"

As much as he hated it, he very much could. But no matter how good it felt he gritted his teeth and said nothing. Even as each thrust against his prostate made his mind almost go blank from the rapturous sensation, he kept his expression apathetic. But while he could make his face appear indifferent, his unattended cock was an entirely different story as it twitched madly, bouncing each time she slammed her shaft deep into his rectum and sending thin strings of precum flying with every impact. To make matters worse, the way his ass was hungrily gripping Saber's length every time she drew back painted an equally damning picture that she was sure to take notice of, and he had to put conscious effort into keeping his hips still.

"Your ass was made for taking huge cocks, Shirou. I should have realized this when I saw you lose to my Master's. But we'll have plenty of opportunities to make up for lost time, and we'll both enjoy every second of it. Fuck … I will need to properly show my gratitude to my Master for arranging this later, somehow. And I have to thank you as well for agreeing to this, Shirou. To think, I can fuck you however I like for as long as I want anytime you want to see my Master. Promise me you'll come here every day, Shirou; in return I promise to use you thoroughly every time you do so. You'll enjoy that, because you like serving big cocks like mine. I can tell you like this especially from the way your ass grips my cock trying to keep it inside you! Admit it! You love it when I use every inch of my big fat cock to fuck you deep in your ass!"

Saber's words painted a harrowing image for what their future interactions would look like, but Shirou refused to shy away from it; he'd known what he was resigning himself to. And as much as he hated it, he felt his ass tighten upon hearing Saber's promise of doing this to him whenever he came to learn from Caster and the undeniable pleasure it would bring them both. Before long he felt the pressure become too much for him to bear as his first climax of the night crashed into him.

Squirt! Squirt!

Watery cum shot out from the tip of his cock, splattering on the ground beneath him. He managed not to make a sound, but it was a close thing. And the strain on his concentration was made all the worse as Saber kept on fucking him balls deep in his ass through his entire orgasm and after.

"Ahh… cumming already? It hasn't even been a minute. Seems your body is eager and willing to admit what your mind is not. Then again I know an anal slut when I see one, being one myself for my Master. But you, Shirou… you might actually surpass me in that field already, even though this is only your second time getting your ass fucked. Hmm. I shouldn't be surprised. Huge cocks are clearly your weakness. You could never have resisted the pleasure this brings you for too long, isn't that right?"

"It's… not… true," he replied through gritted teeth. Getting in even a word amidst Saber's thrusts was difficult enough, and holding back his moans as well made it that much worse.

Even though he had just shot his load, the pleasure didn't stop and in fact his dick seemed to throb even harder as Saber continued to fuck his ass. Unlike when he masturbated, his cock wasn't suffering from overstimulation. It was aching to be touched, he just refused to do it.

"Hmm… then you must be… ahh… a premature ejaculator, is that it?"

Shirou, of course, didn't reply. Not only could he not trust his voice to not crack, he also knew anything he said was only going to give her more ammunition against him. Saber took his silence as a challenge though. She was also getting more used to having a cock and how to use it, adjusting the angle at which she was thrusting it into him and causing even more friction against his weak spot.

"Which is it, Shirou?" she asked. "Do you love big fat girl-cocks that much, or are you a quickshooter? Ahh… it's both, isn't it? I bet it's both. Hnn! A useless man with a useless dick. You could never amount to anything more than this."

Saber's humiliating words cut so deep he almost felt like crying, but at the same time the more she fucked him, the more his body was quivering in ever increasing pleasure. His arms gave out and he had to lean his head on the ground, leaving him with his ass pointed up almost as if he was prostrating himself.

"Hn… hahaha!" she laughed. "Can you see yourself now? Can you see how weak and pathetic you are? Unable to do anything but lie there and be fucked? Can you see that you are a useless faggot?"

Shirou was in no condition to mount even a passing defense of his masculinity. He was biting his lip, while his eyes were getting unfocused and were starting to cross over, and all he could feel was Saber's massive cock being rammed in and out of his ass endlessly along with the impacts of her hips. And even if he could open his mouth and not let out a moan that betrayed how good this felt, could he convincingly deny even a word of what she was saying in his current position, with a thin puddle of his own cum beneath him and another one soon to follow? Could he refute her, when it was taking everything he had not to believe those words as well?

His cock was now constantly leaking and he felt another climax fast approaching.

"Hmm… I am going to cum, Shirou. I'm going to stuff your ass with my seed the way it's meant to be. Hrrm! "

With a final thrust, Saber fully sheathed her cock, releasing her load deep into Shirou's ass, triggering his own climax.

"Ahhn!" Saber moaned aloud.

"..."

Shirou was silent, but his cock spasmed and bounced up and down, shooting cum on the floor underneath him and even on his chest while he felt his gut being filled up with her seed.

'Why does it have to feel so good?'

Pain he could take with his head held high, but pleasure was an entirely different beast. Even the humiliation of Saber's words couldn't take away from the incredible feeling of his prostate being pounded into oblivion that he could only experience from getting fucked in the ass by a cock bigger than he could ever dream of having. None of the times he'd masturbated could even begin to compare. If anything, it made things worse as it cemented the reality that he'd received infinitely greater satisfaction from getting his ass fucked than he ever got from touching his cock, and that made him question himself all the more.

At last, Saber finally stopped to catch her breath, or maybe just savor the afterglow of her orgasm. Either way she kept her cock buried inside him and was kneading his ass with both hands, almost as if praising it for the wonderful experience it just gave her.

"Are you… ready to admit it now?" she asked.

If this was something he was doing only for himself, he might very well have fallen like Rin and Saber had. It would have been so easy in his current state of mind to just say whatever Saber wanted to hear and enjoy what would come next, be it from her or Caster or anyone else. To stop fighting and give them what they wanted so long as it meant he could experience more of this .

But there was no one in the world better than Emiya Shirou at denying himself. Absolutely no one. Therefore, he forced his head up to look over his shoulder back at Saber as he finally met her eyes.

"Are you… done already? I've got places to be."

Saber had a stunned expression on her face, as if she couldn't believe what she was hearing.

"Do you really want to be that difficult? Very well. I can go on much longer. You would do well to brace yourself, Shirou. You heard what my Master said: you will not leave this room so long as I still have even a drop of cum left in my cock to fill your holes with."

True to her words, he could feel that her cock had remained as hard as it had been at the start of all this. That being the case, Shirou could do nothing but do as she suggested as she grabbed his hips and began furiously rutting his ass once again. It was evidently going to be a very long night.

He hated that even a single part of him was looking forward to it.
