Chapter 12

The following chapter contains an AI image that is not as accurate as I would like it to be, but it comes pretty close. It's not an actual depiction of what they look like, just think of it as a visual aid.

Shirou slept in late the next morning, not waking up until around 7AM. He'd been kept up far longer than usual last night by Sakura, both in the sense that she had been telling him her tragic story for a long time, and in the sense that she had well... needed a lot of 'comforting' afterwards.

Technically the two 'events' had happened on different days due to Sakura talking until long after midnight, but still. In all ways that mattered Shirou had slept with both sisters on the same day. It still felt like his mind might just melt if he thought about it too much. It was what he wanted, and the proper role of a Master and Servant, so he couldn't consider what he had done with them to be a mistake. No, what worried him was that it was almost too good. Could any man survive engaging in such pleasure every day?

He was already almost too distracted to even think about the war. When he thought about the way that Rin's body had been pinned beneath him, or the way that Sakura's impressive chest had been squished against his during the act... well, it made it hard to focus on other things.

"No, I can't stop." He said out loud.

Although he had made both decisions under diress, Shirou was proud to be the Master of both Rin and Sakura. He couldn't be someone that held them down. As a Master it was his duty to train them both properly, and if he stopped having them share his bed that would be the same as slacking off and sending them into combat without weapons.

He wasn't sure why, but for some reason Shirou felt like Rin would have throttled him if he had shared that thought out loud.

"Master?" A quiet voice murmered. Sakura's warm body shifted as she slowly came back to consciousness. Her delicate hands rubbed at her eyes, and he couldn't look away from her knowing that underneath the blanket she rested on was her naked body.

His voice must have woken her up. "Sorry, I didn't mean to wake you. I'm going to go and get breakfast. Get some rest, Sakura."

He pulled away at the blanket, intending to crawl out of the futon, but a hand on his arm stopped him. "Wait, Master."

"Sakura?"

Before he even knew what was happening, Sakura had climbed on top of him. Her long purple hair ran down her sides, and he got his first really good look at her. Yesterday it had been too dark to really see, but now that the light illuminated her Sakura was so beautiful that it took his breath away. Her skin was pure and fair, and her curves were soft and alluring. Although it felt cliche, he couldn't deny how his eyes were drawn to her breasts, which were so much larger than he had thought they would be.

"Master." Her breath was warm, and her tone was needy. There wasn't even a hint of the fear and discomfort she had shown him last night. "What kind of Servant would I be if I let you get out of bed with this thing still troubling you..." Her hand gripped his hard cock, which had been erect ever since he had woken up.

Well, indulging in this sort of thing was also the role of the Master.

When he gave his consent, Sakura's eyes lit up. "Okay. Here I come, Master!"

With a soft grip on his cock, Sakura slowly lowered herself down onto Shirou. The spot between her legs was already soaking wet, and she seemed to have no desire for foreplay. With only her Master's pleasure in mind, Sakura pushed him back so that he was fully laid on the bed and assumed a cowgirl position.

"Master!" She cried out, as her hips pressed him further and further inside of herself.

Shirou groaned, already loosing himself to the pleasure. Sakura's insides were warm and inviting, and her body was so damn tight. Every time her inner walls rubbed against him it felt like he might lose his own mind.

"Ah, Ah! I'm so happy, Master!" Sakura called out. "I'm so happy that I'm yours!"

"Yeah, I'll take care of you forever, Sakura." Shirou said.

As if his words had spurred her on, Sakura began to thrust her hips up and down at an even faster rate. Her body rose and fell in a steady, constantly shifting motion. Shirou didn't have to even do a thing, he just laid there while Sakura used her skills to drive both of them to the heights of pleasure.

And although she was doing all of the work, Sakura was clearly enjoying this just as much as he was if not more. Her moans were constant, and her voice was thick with need. Her eyes never once shifted away from his, like she had to convince herself that it was really him beneath her. Really him inside of her.

He fit into her body like he was meant to be there. No, it was more like she just naturally accepted him. Her walls contracted around him as she pumped her hips up and down, like her entire self was devoted to drawing out his seed.

And well – it worked.

"Sakura! It's coming!"

"Yes! Fill me, Master! Fill me up!" Sakura cried, not stopping the rolling of her hips for even a second. Shirou grunted as he reached an orgasm, and his semen spilled out to coat Sakura's insides. She moaned in absolute bliss, and his orgasm triggered her own, causing her to scream "MASTER!" at the top of her lungs.

She collapsed, right on top of him. Shirou held her against himself gratefully, happy to feel her skin against his. For a long time, the two of them just lay there sharing in the joy of each other's bodies.

And for one of the only times in Emiya Household history, breakfast was eaten late.

"So, how's this, Master?"

"Hmm. Good. Good job, Rin."

"Hmmph. I still think you're taking this Servant thing a little too literally." Rin said. Although her words were sharp, her cheeks were bright pink from his praise.

"Sorry, but you two are just too beautiful. As a man, I can't resist." Shirou said, feeling that honesty was the best policy.

That got both of the sisters blushing, as if they weren't already all very intimate with each other's bodies.

Before training today, Shirou had pressed Rin to make maid outfits for both herself and Sakura. She had accepted this time without nearly as much protesting as last time, probably because this outfit covered a lot more skin that the previous one had. But Shirou knew that it had a charm all of it's own. The outfits had longer skirts than he had in mind, but the necklines were low enough to display generous amounts of cleavage. He had to remember to reward Rin for a job well done later on.

Together, the three of them entered the dojo. "So, Sakura. I think it makes most sense to start with seeing what you can do." After all, the only times they had seen her fight, it had been with her mind warped by curses. That may have been holding her back.

"There's one thing I want to verify, Sakura. Where's your mount?" Rin asked.

"Hmm?" Shirou asked.

"My mount..." Sakura said, with her eyes downcast.

Noticing Shirou's confusion, Rin got into her standard tutoring pose and started to explain. "All classes have their own special abilities, right? What makes Rider class servants unique is that they have a mount to bring along with them. And those daggers Sakura was holding certainly weren't her Noble Phantasm, so I'm wondering if her mount is."

"My Noble Phantasm? Ah, it's hard to explain so much at once, Nee-san." Sakura said. A look of guilt crossed her face that made Shirou and Rin both equally confused.

"Sakura? Is there something you don't want to tell us?" Shirou asked.

"No, no! Of course not, Master!" Sakura yelled out, waving her arms around. "It's just, um. A little awkward..."

"Oho?" Rin said, with a wicked smile. "To think a perfect Servant like you would be holding back from your Master like this. Don't tell me you're aiming for a spanking?"

Sakura's face went bright red, and Shirou wasn't sure if she was more embarrassed or angry. "I- I'm not a brat like you, Nee-san! I don't want to make Master mad!"

Rin's delighted expression broke. "Hey. Just what are you implying, Sakura?"

"Isn't that obvious?" Sakura asked. Although she was trying to act high and mighty, it was obvious that she was emotionally very out of her depth. "You're the kind of Servant that acts up because you wants Master to punish you. Well, you have an unexpectedly soft side that likes being praised, but at your core you want to push back against Master and have him overpower you. All I want is to serve. I'm a good girl, right Master!?"

"Yeah, of course you are, Sakura." Shirou said.

"Don't give me that kind of characterization!" Rin yelled, making Shirou flinch away from her. "I-I-I- I have never had that kind of thought in my life! W-well, I can't deny that sometimes I get excited when I'm being punished, but that's not something I would ever pursue on my own!"

"Nee-san can't be honest with herself, huh?" Sakura asked.

Shirou put his arms up between his two Servants, stopping them in their tracks. "Hold on, hold on. We're getting off track. Sakura, do you have some kind of mount?" Sakura and Rin both flinched like he was about to punish them for acting out, but he couldn't do that. He was the one who had ordered them to act like sisters. It would be beyond hypocritical of him to punish them for obeying.

Besides, it would be lonely if this house was never loud like that...

"My mount." Sakura said, with her shoulders dripping. "Well, it's not that I don't have one. It's just that the conditions for bringing it out are..."

Her expression turned even darker.

"They might be difficult."

"What do you mean?" Rin asked. She was all business again now. "Start at the beginning."

"I- I have two Noble Phantasms." Sakura said. She looked guilty even talking about it, and afraid about how he would react. "One of them is a kind of bounded field that – consumes people."

"Consumes people?" Shirou asked. In his mind's eye, he saw a brief glimpse of the Fire. His expression hardened for a second until he saw the shame in Sakura's eyes and he made himself smile. "Don't worry, Sakura. Whatever it is, I won't judge you for it."

"...Thank you, Master." Sakura said. "It's a Noble Phantasm that consumes the lives of others to provide me with magical energy. I do have a mount. I think that aside from the dragons, it's the strongest mount in the world. However, to call him out would require more magical energy than I currently have. And since I'm not getting any from you, Master. I would need to..."

"Hold it. You don't have to say it." Shirou said. He put his hands on Sakura's shoulders. "I swear to you, Sakura. I'll never make you use that thing."

"Master..." Sakura said, looking up at him with a wide and grateful smile. "Thank you."

"Hmmph." Rin pouted for some reason. "So, your other Noble Phantasm lets you summon your mount with your accumulated magical energy?"

Sakura jumped, having seemingly forgotten that Rin was still in the room. "No, not exactly. Bringing Pegasus here is more like a technique. My other Noble Phantasm is what lets me control him." A set of items appeared in her hands, a golden bridle and a whip. "Unfortunately, they can't do anything without Pegasus."

"Pegasus?" Shirou asked. Even he knew that famous mount, the flying horse of a Greek hero. "Does that mean the Servant inside of you is Perseues?"

"No. I am, I contain... the Heroic Spirit Medusa." Sakura said.

"Medusa!?" Rin yelled. "Shouldn't we be turning to stone just from looking at you!"

"I think the real Medusa would do that, but for me that's just a skill I can choose to activate or not. Um, it's useful but it can't really differentiate friend from foe and it takes a lot of magical energy to use." Sakura said, consoling her sister.

Shirou nodded, filing that information away. He didn't really care about what Heroic Spirits they had summoned, aside from how it might influence their strategy. All that mattered to him was that they were Rin and Sakura. His Servants. "Right. Then, next up, let's get to sparring."

X X X

They learned a few things about one another over the next few hours.

First, Sakura couldn't use any of the Noble Phantasms that Rin had created. Whatever part of the Master-Servant bond that allowed him to use her weapons, it didn't exist between the two sisters.

Second, now that Sakura was no longer being held back by her mental restraints, her attributes and raw power far exceeded those of Rin. Rin could still fight through clever tactics, and her diverse range of Noble Phantasms, but in terms of sheer combat power Sakura was far faster and stronger. Shirou thought it was only natural that an Archer couldn't match a Rider in a fight from close distance, but Rin still took it rather badly.

Third, Rin could project Sakura's chained daggers, but they weren't as useful as actual Noble Phantasms.

And fourth and finally, his dojo was nowhere near sturdy enough to act as a testing ground for Servants. If this continued for much longer, it would destroy the entire house.

"Okay, let's call it a break there." Shirou said, waving to both of them. Sakura and Rin nodded at one another, both dismissing their weapons. Rin's maid outfits still covered them both, but there had been more than a few moments where particularly powerful blows had robbed one or the other of their clothing. Rin's projected outfits were not suited for real fighting. "You two did great. Let's go eat."

"Thank you, Master." The two of them said in unison.

"Nee-san?" Sakura asked, and Shirou was happy the ice between them seemed to have broken so easily. "Why do you keep defaulting to those two blades. You can make any Noble Phantasm you want, right?"

"Hmm? I don't know." Rin admitted. "I just feel like they're suited for me. Or for the Heroic Spirit inside of me at least. They feel... natural."

Shirou nodded enthusiastically. They were truly beautiful.

"Master?" Sakura asked.

"Huh? Oh, sorry." Shirou said. He hadn't meant to say that out loud. "It's just... I agree with Rin. Those two swords might not be the strongest, but they were... they were made just for the sake of making something beautiful. When I look at them, I can't help but get jealous. I'd love to have weapons like that of my own."

Rin puffed up her chest in pride. Sakura looked scandalized. "M-master!? You want my weapons too, right!?"

Shirou titled his head, confused but happy when the two sisters started to argue.

He let them go, happy for the distraction that would allow him to make lunch without argument. After they ate, he would have the two of them give him some combat training. And after that...

It was time to pay Sakura's grandfather a visit. Right now, with the power of Servants inside of them and Sakura free from his clutches, they were better posed to take him now than they might ever be again.

Shirou had done his best to keep a straight face, but he remembered what Sakura had told him about what that monster had done to her. It was going to be time for that man to learn what happened to those who hurt his Servants.

His ideals as a Hero of Justice, and his ideals as a Master were in perfect sync. It was time for Matou Zouken to die.

And of course, just because Zouken is dead doesn't mean our trio know that he is.
