Chapter Ten

Dinner was an awkward affair. Shirou wasn't sure what he had done wrong, in fact he thought the salmon he had made had come out rather well. But for some reason, there was a tense silence hanging between the three of them.

Rin and Sakura were sitting on opposite ends of the table, and Rin was refusing to look either him or Sakura in the eyes. Sakura on the other hand looked almost boastful, in fact more than a little smug if he was being honest with himself. Ever since she had serviced him with her breasts she had been walking around like she owned the place.

Shirou took his final bite with a sigh, and then respectfully placed down his chopsticks. "Alright. I want to make a plan for tomorrow."

He'd been hoping for immediate enthusiasm, but was disappointed. Rin shot him a wary look, while Sakura still seemed to have her head up in the clouds.

He frowned. "Sakura, if you're still sure you're feeling better I think we should start going on patrol tomorrow. The longer this war lasts, the more danger people are in. I shouldn't have any trouble convincing Fuji-Nee to let me stay home again tomorrow, so we can spend the morning with training and head out when it turns dark. Do you think you would be up to that?"

"Absolutely, Master!" Sakura shouted, her expression turning determined. "Just give me the order."

It was a troubling answer in it's own right. Obedience was good, but he hated the idea that she might be hiding her own injury to please him. "Rin, how about you?"

"...Yes, Master." Rin said. Her tone was dark, lacking any of the enthusiasm she had once given him. Her stare was turning even harsher. "Master, I have a request."

"A request?" He parroted back. Something about this just didn't seem like her. "What is it?"

Rin took a long deep breath. "I want... I saw what you were doing with Sakura." He started, but saw Sakura puff up her chest in pride for some reason. "In the future, I want you to restrict all such... activities, to me."

"Huh?" He asked, hardly believing the words that were coming out of Rin's mouth.

If he was surprised, Sakura was shaken to her core. She slammed a hand down on the table and screamed a response. "That's not fair, Nee-san!"

"Fair!?" Rin shouted in response. "I'm doing this for your sake! You shouldn't have to –"

"It's a Servant's duty to serve her Master!" Sakura shouted.

Rin banged her own hand onto the table in turn, and Shirou had to grab at his bowls to keep them from shaking too hard. Rin's face was entirely flushed red, but she powered on despite how clearly uncomfortable she was. "And the only one who should have to go through with that is me! I made Shirou into my Master by choice. You only did it unconsciously so that we could save your life. There's no reason for you to have to be degraded like I am!"

Sakura pouted, and Shirou wondered if the two of them even remembered that he was there. "Don't be so selfish, Nee-san!" Nee-san?

"Selfish!?" Rin demanded. "I'm just saying, there's no need for you to have to suffer like that."

Sakura's eyes narrowed. "You're just trying to hog Master all to yourself. I won't allow it!"

"Are you trying to imply that I'm enjoying this situation!?" Rin yelled. She jumped to her feet, shaking the table yet again.

"That's right!" Sakura responded. Responding to Rin's enthusiasm with matching zeal, she too leaped to her feet which sent all of the bowls Shirou wasn't currently gripping on to clattering all over the place.

"Hey, stop it!" Shirou called out. Both of his Servants froze in mid sentence, snapping their attention towards him while he regretfully picked up the pieces. Like he'd thought, they seemed to have forgotten that he was there.

Neither of them seemed to want to back down, but Sakura broke first. "Sorry, Master." She said, bowing her head to him.

"...Sorry, Master." Rin followed up a few seconds later, sounding far less genuinely apologetic than Sakura had.

"Geez, you two." Shirou said, shaking his head. He really didn't know what had gotten over them. "There's a lot of things I want to ask but to start, Sakura, why were you calling Rin Nee-san?"

In the silence that followed, Shirou could have heard a pin drop from anywhere in the house. Sakura and Rin didn't just stop talking, they completely stopped moving and breathing as well. He raised an eyebrow, waiting for an answer, but the two Servants just stood there in mutually agreed upon silence.

"...Master, I'm sorry but I can't tell you about that." Rin said. She crossed her arms, doing her best to look defiant.

Shirou looked over to Sakura. He expected her to break, but she was just staring at the wall without making a move.

He sighed and stood up. "Alright, alright. Both of you get over here and bend over the table."

"Yes, Master." Sakura muttered under her breath as she nearly silently began to follow his order.

Rin however turned energetic again and started waving her arms around. "Wait, wait, Master! I told you to leave Sakura out of that sort of thing! I'll take whatever punishment you want to deal out!"

Sakura pouted again, as she bent over the table beside Shirou. "Don't be selfish, Tohsaka-Senpai."

"Just what about that is selfish!?"

"Rin." Shirou said. "You're both withholding information from your Master, so it wouldn't make sense for only one of you to punish. Now hurry up, or else I won't let you wear clothes for the rest of the day."

Rin flinched back, her cheeks blushing red as she lost the ability to look him in the eyes. He saw the fight in her eyes diminish quickly, and soon she was bent over the table alongside Sakura.

Seeing both of the servants bent over like that, fully clothed but still presenting themselves to him in a way, made Shirou start feeling excited. He knew he shouldn't, this was punishment not part of a reward, but seeing the two of them like that would get any man's blood pumping. Their body types were very dissimilar, but the two were equally attractive in their own ways. Sakura had the larger breasts despite being younger, but Rin had an athletic figure and an attitude that made him want to ravish her uncontrollably.

Shirou shook his head to clear his thoughts. It was irresponsible of him as a Master to let his lusts get in the way of something like this. "Both of you, lift up your skirts."

The two of them responded in perfect sync, with equally muted voices. "Yes, Master." They said. Shirou was soon greeted with another even better sight, as the two young women exposed themselves at his command. Sakura's panties, projected by Rin, were a conservative pair of plain white panties. Rin's were smaller however, a cute pink that exposed much more of her backside.

Not that either pair mattered for long. Shirou hooked a finger through each of them and pulled down, exposing the private areas of each of his Servants. The two women gasped softly as they were fully exposed, and he noted with no surprise that both of them were rapidly growing rather wet.

Shirou raised a hand and without warning brought it down in a sharp spank across Rin's ass. "Ow!" She cried out in pain, squirming beneath him. He followed that up with another quick slap onto Sakura, whose response resembled more of a moan than a cry of pain.

"You're each going to get ten strokes for lying. Rin, you get five more for hesitating." Shirou explained. Even as he spoke he didn't stop spanking them, drawing out cries of mixed pain and pleasure.

"H-Hey!" Rin protested. "I l-listened!"

"I can't have you waiting to follow orders like that. It could be dangerous." Shirou said, shaking his head at her. "So – I need to train that out of you."

Rin whimpered, and he saw one of her hands begin to drift between her legs. Shirou dragged it away. He was fine with her also enjoying this, that couldn't be avoided, but if she was just getting off on it then there would be no improvement.

Again and again his hand flashed downwards, striking at each of his Servant's without order. He kept a careful count, but didn't limit himself to switching back and forth in a way that would be easy to predict. Instead he moved at random, hitting Sakura on each cheek once and then Rin once, and then Sakura once before three times on Rin, and so on as disordered as he could make them.

His hand began to sting as well. He could have reinforced it to prevent any pain, but that felt like cheating to him. If he was going to be hurting his Servants, it was only fair that he knew exactly how much they were receiving. Besides, he couldn't deny that it was pleasant indeed to feel his hand clash against the bare flesh of their backsides. The riding crop had been fun, but this was a different type of enjoyment.

By the time the fifteen and ten spankings had been delivered, both women were panting. Rin more than Sakura of course, given how there were five more red marks across her butt, but both of them were breathing heavily. The wetness between their legs had only increased with each part of the beating.

Shirou nodded, pleased at the sight. "Okay, those were for lying. Now this is going to continue until someone tells me the truth. Sakura, why did you call her Nee-san?"

His hand rose up, but he never needed to bring it down.

"She's my sister!" Rin called out. Her face was buried against the table. "She was my sister." She said again a second later.

Sakura gasped, looking over at her... sister? How could that be? "Nee-san?" She asked, with a surprisingly gentle voice.

"Sister?" Shirou asked. It was the simple answer to his question. Why had she called her sister? Because they were sisters. But it was still hard to believe. Sakura was related to Shinji, she'd never even spoken to Sakura before. That he knew of. "How?"

"Magecraft families can only have one heir." Rin said. She didn't look over at Sakura, although her sister was staring at her with wide eyes. "That's an ironclad rule. For my father who had both me and Sakura, that meant only one of us could inherent his position and the other would only be a rival or a spare. So he decided to send Sakura away, and when we were children she became a Matou. From that day on, he said I was forbidden to see her as a sister."

Shirou thought of Fuji-Nee, and how he would handle it if someone told her he could never see her again. "How cruel." He said.

"It's the way of Magi. That's all." Rin said. Her voice sounded muffled, with her face still buried against the table.

"Master, can I leave now?" Sakura asked. Shirou looked over at her, unable to hold back a rising sense of lust as he saw her chest rise and fall while her exposed backside was presented to him.

"Hmm? One second." He said, and she obediently fell back into place. Shirou put his hands together. "All right. I don't know what came about before, or what's gone on between the two of you since then. But right now, I'm giving you a new order. For as long as you are both my Servants, you are to act as sisters, got it?"

The two of them started, gasping at his order. They looked at one another, feeling the weight of their history as they shared in the moment.

Shirou gave them both an extra spanking each. "Hey. You two know what to say when given an order, don't you?"

"Y-yes, Master!" Rin called out.

"Yes, Master. Thank you, Master." Sakura said. "Can I go now?"

Shirou nodded. "Alright. You can get some rest, if you need it."

"Thank you, Master." Sakura repeated. She pulled herself up, gathering up her panties and letting her skirt fall back downwards while watching Rin with a clouded expression. As she was leaving, she stopped at the door. "Nee-san? I won't be sneaking a peak like you did, so have whatever fun with Master that you want."

"Sakura!?" Rin yelled, her eyes going wide. "What was that supposed to mean!?"

Sakura didn't respond, leaving the two of them alone while she wondered off.

Shirou leaned over Rin, pressing her light body against the table below him. She moaned, not seeming to realize she was making the sound, as he pressed a kiss to her cheek. "You did good, Rin. Thank you for telling me. I'm proud of you."

She could only whimper in response.

His hand drifted downwards, slipping between her spread legs. The spanking had left her soaking wet and ready, and he could see the need in her eyes.

She gasped and moaned. "Master... Master...?"

"Yes?"

"Master... you don't have to just use your hand. This time. If you want." Rin said.

Shirou smiled, and began undoing the button of his pants. Watching the two gorgeous sisters grow progressively more aroused because of his punishment had been driving him crazy, and when he pulled down the band of his underwear his erection practically sprung out. He was burning hot with desire, and Rin had a passion to match him.

He wasted no time in lining up his length against the wet spot between Rin's legs. "Master, please." She begged, urging him onwards. Shirou grunted and thrust forward, spearing her with his length. The feeling of being surrounded by her was unlike anything he had ever known before, in a uniquely pleasant way. Rin was tight and wet, and her body contracted around him as she gasped and moaned.

"Good girl." He whispered, and Rin suddenly pulsed tighter around him. He leaned closer to her, pressing his weight against hers and his hips began to pump in and out of her formerly virgin body. Her hymen must have been pierced earlier, because although he knew she had no experiences beforehand there was no blood or resistance to his constant skewering of her body.

"Master!" Rin cried out, her face twisting into an expression of absolute ecstacy. "Master! It feels so good, Master!"

"You're doing so well, Rin. Doesn't it feel good to take your Master's cock like this?" Shirou asked. Rin nodded frantically beneath him. "You're doing such a good job Rin. This is what you were made for, isn't it?"

"I- I was made to take your cock, Master!" Rin cried. Shouting the words made her cheeks flare up again, but she didn't stop moaning and begging for more.

Shirou's hand spanked her hard once again, noting with pleasure that she tightened around him when she did so. His cock felt like it was being pushed to it's limits, trying to continually push in and out of her at such a speed that it was a miracle he hadn't finished yet. But Rin only wanted more and more, the athletic woman silently and sometimes openly begging him to fuck her faster and harder.

"You're such a good girl, Rin." Shirou said, he found that continuing to speak made her more pliable and easy to drive to the heights of pleasure. "Good girl, good girl. Master is so proud of you. You'll take my cock whenever I want, right Rin?"

"Yes Master! My body – my body belongs to you Master!" Rin cried out. He felt her tighten even more, her legs almost seeming to go limp as something that had been building for a long time now threatened to spill out. "Master! I'm cumming, Master!"

"Rin!" Shirou shouted in response. As her body shuddered and she moaned beneath him, he took the chance to stop holding back what he had been holding in for far too long. His cock pulsed as he released stream after stream of his warm semen inside of Rin's body, filling her completely with his seed. She didn't protest even the slightest bit, accepting it all with a smile.

When he was spent, and she had come down from the high of the orgasm, he picked her up and delicately settled her in his lap. She clung tightly to his neck, still grinning like a madwoman.

"You did so good, Rin. Your Master is so proud of you. You did a good job for Master, Rin."

She gulped in, and he saw something shift deep inside of her. "...Thank you, Master. Like I said, my body's yours so... use me whenever you want, okay?"

Shirou just chuckled, enjoying the warmth of her body against his. "Don't worry Rin. You'll have to hold me back."

Shirou did not see Sakura again until that night. He had settled into his room, fully intent on giving the sisters the chance to rest and catch their breaths until morning, when he heard a knock on the door. "Come in!" He called out.

Sakura opened the door, as naked as the day she was born. Shirou sputtered, so lost in the sight of her beautiful womanly curves that he couldn't speak for a second. "Master?" Sakura asked, not making a move towards him.

"Sakura?" He responded, realizing how dazed and stupid he sounded. "Come here."

His lame response still made her smile. Sakura strode over towards him, and then knelt at the end of his bed. "Master... there's something I have to tell you. About me."

He leaned down, taking his head in her hands and stroking her hair. "You can tell me anything Sakura. I promise."

"I- " She looked down, but didn't lean away from his touch. "I'm so sorry, Master. I wish – I wish I could be fully yours. The way Nee-San is. But I was already sullied a long time ago."

Shirou tugged on her hair harder than he had intended to, making her jump in shock. "Hey. Don't say stuff like that. What are you talking about?"

Sakura gulped, looking up at him with such guilt in her eyes that he wanted to wrap her up in a hug that would never end. "It's a long story. It started like this, Master..."

For a long time, Shirou stroked her hair and listened as she talked all through the night.
