This chapter is very focused on the BDSM side of this story. Almost exclusively in fact. The next story will have some more important plot development but... well, I just wanted to write this stuff.

Chapter 15

There were many things that Sakura was afraid of, all with very good reason, but every day she got to wake up in the Emiya household, and that was enough to keep her calm and happy. Any day it might be upset. Her Grandfather could return from wherever he was in hiding. That Caster could kill her Master like she had tried last night. Or another Servant could do the same to her or Rin. Anything could happen. Even if this was a brief and fading dream though, it was better than anything she had ever known before. So she would savour it.

She had always woken up early. Well, for the last couple of years at least she had. Ever since she had started coming to the Emiya estate in the mornings, and found a life outside of her daily hell. She'd pushed herself to wake up as early as possible, in order to maximize her time here.

Besides, when she got up early she was the one who got to cook breakfast.

The pan sizzled, and Sakura smiled in appreciation as the eggs spread out without breaking. There had been a time when she could never crack an egg without the yolk shattering. She was doing a western style breakfast today, mainly because it had been a long time since anyone had been out shopping and they were running low on the ingredients for Japanese style breakfast. But they had plenty of bread.

The sounds and smells of the cooking lulled her into a sense of joy and ease, so she almost didn't notice when her Master slipped into the kitchen and promptly began to stare at her.

Sakura giggled. She was wearing an apron – and nothing else. Her sister had gotten to do it, hadn't she? It was only fair. "Good morning, Master." She told him, with a smile.

The sheer joy in his eyes as he stared at her made her heart want to flutter. Her Master was an attractive man, with bright red hair and a handsome face. He worked out, and his muscles were both well defined and absolutely joyous to touch. But she didn't love him just because of that. He was also cute. He got embarrassed easily, and was adorably stubborn. When he wanted something, when he focused on it, he sought after it with utter relentlessness that no normal man could uphold for long.

And now he was looking at her like she was his prized possession, and Sakura thanked every god she could that she got to belong to him.

"Master?" She repeated. He hadn't said anything, but he did step forward after hearing her question and wrap his arms around her from behind. She gasped a little.

"Good morning, Sakura."

His hands slipped under her apron and began to massage her breasts. Sakura moaned in bliss. Her body had started reacting to his presence as soon as he'd touched her, and she couldn't be happier to have proof that he really wanted to do this with her. This was the first time he'd been the one to initiate.

She barely had the frame of mind to remember to turn off the stove top as he led her into the kitchen. Without even saying a word, he got her to lay on her back on the kitchen table and she heard his zipper come undone just before his pants hit the floor behind her.

Her whole body was warm. She could not have been more willing, and more ready for him if she actively tried. There was an aching need inside of her, and she would have given him anything in return for quenching it.

Sakura screamed in joy as he took her.

Something smelled a little strange as Rin ate breakfast that morning. She'd been half-dragged out of bed by her Master, and aside from Sakura's frizzled hair and naked-apron everything seemed perfectly normal. But something just smelled... weird. Something about the table?

She remembered what had happened only a few nights ago, and she had to hide her blush. She was sitting in the same spot where she had lost her virginity. Had the smell lasted that long? Desperate to hide her embarrassment, she pretended she hadn't noticed anything.

"Here, Nee-san, let me handle the dishes." Sakura said. She was in a good mood this morning, for some reason. Rin was personally still a little too worried about what the two enemy servants to relax like that, but she was glad that her sister had managed to find some manner of stress relief. Whatever it was.

"Thanks, Sakura." Rin said, handing over her plate.

Breakfast had been good. Great, in fact. Rin had missed having Western style breakfasts since coming here. The food had been too good for her to complain about, but she had been developing a crazing. Both her sister and her Master were excellent cooks, and Rin was already hard at work trying to imagine a dinner that would allow her to defeat them both.

Perhaps if she... no maybe if... ooh, that could work.

"Rin, what's with the look on your face?" Her Master asked her. He was almost pouting while looking at her, and she wondered just how devious her expression had been.

"What do you mean, Master? Am I not allowed to smile?" Rin asked, hiding her expression behind a hand to emphasize it.

Her Master sighed, shaking his head at her.

Rin's smile widened. She was at a turning point now. She could very easily drop this here, and it would never be brought up again. But her instincts were screaming at her. Telling her that all she had to do was push just a little and the results would be terribly fun.

"Isn't it a little shameful for a Master to distrust his Servants to that extent?" Rin asked, pressing on even as her Master started to frown. That serious look on his face was unbearably cute. Just a little more. "Well? Don't you have a response? It's even more shameful how easily I can push you around, Master."

He snapped. Rin saw the shift in his expression the moment it happened and knew that what was about to come was entirely her own fault. And something about that was satisfying on a deep level.

His frown deepened, and he shifted over towards her without warning. "Rin, don't I still owe you a spanking?"

He grabbed her arms, throwing her over his lap. Something about being manhandled this easily was so fun for reasons Rin could not explain. Her Master's hand held her arms pinned in place behind her back, and although the strength of a Servant would have allowed her to escape easily, she made no attempt to. She was lying on her stomach over his lap, as he sat on the floor, so she had room to kick her legs helpessly but not much else.

"Hey! What are you doing!?" She called out, although she knew perfectly well and was quite looking forward to it. Shame made her cheeks blush bright red, because she knew it was unbecoming of a Tohsaka to be enjoying this, but she could not help the way she felt.

Her Master's strong hands easily flipped up her skirt and pulled down the small red thong she had projected to wear that morning. "Rin. This is for arguing with your Master in a combat situation about pointless nonsense."

Pointless nonsense? Did he not understand just how many jewels she could afford with those stolen books? "I – "

Her chance to respond was cut off when his open palm slapped against her bottom, making her squeal. The pain was intense, in all the right ways. His hand remained on her skin after the sharp contact, soothing the red spot. Her thighs started to rub together unconsciously, but she went right back to kicking when she felt his hand slipped away.

The second spanking hit her on the other cheek, and Rin barely held in her instinctual moan. It was so good. It wasn't that it didn't hurt, but that something about being treated like this made her feel so warm and safe inside despite the blatant contradiction.

Again and again her Master's hand fell downwards to strike her ass and thighs, leaving little red imprints with every blow. It didn't take long before Rin lost her composure, and her ability to pretend that she wasn't enjoying this. Why lie? He could see how wet she was.

Her restrained hands longed to creep down between her legs, but they were held fast. She was close to humping his leg, and the only reason she did not was because she couldn't figure out how to do so in this position. "Master..." She whined, wishing her voice could have sounded less pathetic.

He might as well have been a stone for all the reaction she got. He delivered another quick and sharp spank, making Rin moan as an already damaged spot grew even warmer. Her skin was so flush all over, she felt like she was overheating. And there was such a need between her legs, she couldn't take it anymore.

"Master please. I need... to cum." She said. She grew even redder as the words left her lips, but she couldn't hold them back.

"Good girls get to cum." Her Master responded. Truthfully his voice was wavering, less strict and heartless than it should have sounded, but Rin was too drunk on the pain and rough treatment to really register that. "Have you been good, Rin?"

"Maaassstter." She whined, burying her face into the ground. It sounded stupid, but although she wanted to be punished she also wanted to be praised. She needed that just as much as she needed a warm rod between her legs. She needed to convince him that she was good. She could do that. "Master, I – ow! I wore this thong for you, Master. My body is yours so – ah! So please use it, Master!"

Yes, that was right. Her body belonged to him. There was no shame in being used, if she couldn't help it.

"Hmmm. That's a good start, Rin." He said. Even Rin knew that he was accepting her too easily, basically just looking for an excuse to do so, but she didn't care. He released the arms he had pinning her in place and put his hand mercifully between her legs. Rin's eyes threatened to roll back into her head as he put his palm flat against her wet mound.

"Master!" She screamed, as he gently, gently, teased at her clitoris.

It was too much. She couldn't have held it in even if she tried.

Still being actively spanked, Rin came all over his lap, burying her face into the floor as waves of pleasure washed over her. When it was over, she found her hair being stroked as her Master warmly eased life back into her sore and thoroughly satisfied body.

It would hurt to sit down for the rest of the day. She could have avoided all of it by just not teasing him. But somehow, she didn't consider that a mistake.

Sakura put the last of the dishes away, listening with an impressed ear as her sister screamed and wailed during her orgasm. She could never get that loud. She hadn't even managed to wake Rin up when she had been getting fucked into a puddle only a short time ago. Some part of her, a part that she was failing to silence, seethed with jealousy as she watched her sister greedily accept her punishment.

Master had been so gentle with her. He was always gentle. The only time she had ever been spanked was alongside her sister. Sakura still had fond memories of the way his hand had turned her skin red, but there had been no repeats of the event. Meanwhile Rin seemed to get spanked every day.

It wasn't fair.

She knew why it was happening of course. Rin acted out and Sakura behaved. It was only natural that Rin would get punished more. But it still felt unfair.

She was still stewing in those thoughts even after her Master had finished giving Rin aftercare to nurse her back to health, and the three of them had once again gathered around the table to discuss matters. Rin's posture was a little awkward, she was clearly trying to pretend her ass wasn't sore, but she still was quick to take over the conversation.

"So, can I have some time before we begin our strategy meeting, Master? I have an idea, but I need to do a few experiments first before I know if it's feasible or not." Rin said. "Unless either of you have any ideas?"

Sakura shook her head, looking to her Master for support, but he was also frowning and looking discontent. "No, I can't think of anything. Aside from defeating them individually."

"We would need some way of finding them to make that happen, Master." Rin said.

Master sighed. "I know." He slapped his hand against his thigh, as if trying to shake away his own negative thoughts. "Okay, let's take today to rest in that case. Rin, I want you to make outfits for yourself and Sakura, got it?"

"Yes, Master. I expected nothing less." Rin said, and this time there wasn't even a trace of defiance in her response. She must have still been too overjoyed from her orgasm to be her usual tsundere self.

Sakura perked up. The maid outfit of yesterday had been fun, and she was glad the experience would be repeated. The clothing itself wasn't super important to her, but she loved the feeling of knowing that she was desired by her Master, and that he was lusting after her.

The costumes her Master selected for today were playboy bunny outfits, which was not what she had expected but not unwelcome. She and Rin openly changed in front of him, Sakura very happy about how his eyes traced over her body, while Rin did her best to hide the sight of the handprints left all over her ass. The clothing itself was essentially a one-piece leotard which left a lot of cleavage displayed, and had a puffy tail accessory over her butt. In addition to that she was given a pair of bunny ears on a headband, and a leather collar which she happily wrapped around her throat. It had a very comforting feeling, the collar, she enjoyed how much it highlighted that she belonged to her Master.

Master nodded in appreciation, openly ogling the two of them as they dressed themselves. "Hmm... there's one thing missing."

And for the first time in her life, Sakura was given a pair of high-heeled shoes to wear. She had to admit her Master was right, they really were necessary to complete the outfit, but that didn't mean she was comfortable with them. Even to stand, she needed to balance with one hand on the wall. Still she did her best to smile. She wanted to be a good girl, and good girls did what their Master said even if it was a little bit difficult.

"Master, can I borrow you for a minute?" Rin asked. Her face was red despite her best efforts to hide it, but Sakura thought the outfit fit her very well. Although obviously she didn't have much of a chest to show off, like Sakura did. Heh.

"Yeah, of course." Master said, letting Rin lead him away.

With the dishes done, Sakura had no more chores that she needed to get started on right away, so she decided that if she was going to be wearing these heels for the rest of the day she might as well get some practice in now. Slowly, using the walls of the building to stay upright, she wandered into the dojo. The largely empty space was the best place she could think of to practice.

Sakura had heard women complain before that high heels began to hurt after a while, but in her Servant's body she didn't share those concerns. She could have spent the day hoping around on one toe without hurting anything. No, her issue was balance. How exactly did those fancy ladies she saw on television manage to walk so smoothly with these things on?

There was nothing else to do but practice, since above all else she wanted to please her Master. Sakura kept one hand on the dojo wall, as she slowly made her way around the room in a loop.

She was so into the practice that she didn't even notice when her Master walked into the room. She bumped into him, and soon lost all balance. "Ah!" She cried out as she tumbled to the floor.

A short fall wouldn't have hurt a Servant, but her Master was still quick to catch her in his strong arms. Sakura swooned, momentarily too happy to be ashamed by her misstep as she felt his muscular arms surrounded her and lift her back to his feet.

Holding onto one of his hands to balance herself, Sakura felt her face go bright red. "Sorry, Master!" She cried out, bowing her head to him.

He just laughed, as kind as ever. "It's okay, it's okay. I should have realized you would need practice before putting those on without help."

On any other day, his benevolent nature would have brought a smile to her face or made her feel at peace. But there was still jealousy warring within her heart. Although she wanted to pretend otherwise, she was still thinking about this morning, watching her sister get so roughly spanked beside the kitchen table. Rin had gotten that just for talking back. Meanwhile Sakura could crash into his like this and got nothing but a few words.

Her agony must have been showing itself on her face, because her Master looked concerned. "Sakura, is anything wrong?"

"Master..." She gulped. It felt wrong to talk about this, but she told herself that it was her duty to answer him to the best of her abilities. "You don't have to treat me so delicately all the time. Like Nee-san, I um, I also... I know I deserve to be punished from time to time."

"You do?" He asked. The genuinely puzzled look on his face made her want to kiss him. "But I... honestly can only think of one time when you ever disobeyed me. Rin usually pushes me, doesn't she?"

"I... I..." Sakura cringed. Despite herself she couldn't come out and say it. "I want to be a good girl, Master. But I still... still need... discipline."

"But you haven't done anything wrong." He said, before frowning at her. Then a light seemed to ignite within him. "Ah. But... I think you need some training, Sakura."

Her heart started to beat faster. Did he mean what she thought he meant? "Master?"

He steeled himself, straightening his spine as he looked deep into her eyes. Sakura felt herself starting to melt already. He held out a hand expectantly. "Sakura. Give me Bellerophon."

She gasped, thrown off guard by the order. But she was nothing if not loyal to her Master. Sakura called forth the golden bridle, useless without it's mount, and handed it over along with the whip.

Her Master pulled the straps of the bridle apart and threw the contraption over Sakura's confused body. She felt her breath begin to quicken as the cords began to bite into her skin, constricting her from her chest up at all angles. Her Master grabbed her arms, twisting them around her back before they too were bound.

Sakura was a Servant. There was no normal rope or binding that could hold her in place, but this was a Noble Phantasm. It surrounded her on all ends, stealing away her freedom and leaving her completely at the mercy of her Master.

Sakura barely had time to moan before the bit went into her mouth, taking away her ability to talk beyond a mumble. She was little more than an animal now. The heat between her legs grew even warmer, and if she could manage to rub her thighs together she would have been doing so long ago.

Her Master stepped around her, using one hand to hold onto her reins while the other held the whip she had given him ready. "Okay, Sakura. Take a deep breath."

It was hard with the bit in her mouth and the near constant urge to moan that she was fighting down, but Sakura did as she was told. She always would.

"Good girl. Master is proud of you." He stroked her hair, and Sakura leaned into his touch. "While you're like this you're going to tap your foot once for yes and twice for no. Understood?"

It was a struggle, but Sakura managed to lift her right foot and tap it down again before she fell over. Without using her arms to hold herself up this was all suddenly a lot harder than it had been a moment ago. As a reward her Master squeezed one of her breasts gently, sending a jolt of pleasure through her body.

"Good girl." He repeated. He took an expectant step back. "Now, take a step."

Sakura obeyed. She was clumsy of course, and barely managed to stay upright even after only taking a single step forward. She barely even had time to steady herself before she felt a sharp pain spread across her ass, and she moaned in time with the loud crack of the whip. Sakura could not explain why she enjoyed pain so much. Only, it made her feel warm inside and it was a perfect reminder that she was owned.

Sakura Matou was the property of Shirou Emiya. Even disregarding the grail war, she wanted that more than anything.

"Try again." Her Master commanded.

Sakura wasn't sure if the noise she made in response was a whimper or a moan, but either way she was so turned on that it was hard to think. She took another step, this time almost collapsing to her knees. Her Master was there to catch her, pulling her upright and then striking her twice with the whip. Each stroke left a searing pain on her flesh that made her want to throw herself into his arms.

But she couldn't do that. Sakura wanted to please him. She wanted to succeed.

Sakura steadied herself and took another step. It was better than the last one, but still nowhere near steady. Her moan when the whip again struck her skin made her fear that the entire neighbourhood might have heard. She stepped again. And again. And again. Each time the whip descended, while her Master's steady hand kept her from falling to the ground. Each time it left an imprint on her skin, Sakura got a very compelling reason not to make that mistake again.

By the time she had got to the other end of the dojo, she was finally taking perfectly balanced steps.

"Good girl, Sakura. You did so well." Master said. He swept her up into his arms, suffusing her with warmth. The pride in his voice made her feel like melting against him. "Good girl."

His hands drifted downwards, between her legs. Every part of her backside and much of her thighs hurt, and the pain continued to ache even as his fingers pressed against her lower lips. The hurt only made the pleasure all the sweeter.

It didn't take long for him to drive her to an orgasm.

He held her as she shook. "Thank you, Sakura. You did so well. We'll take a break now, okay?"

But Sakura, even having come down from the high of her orgasm, didn't want a break. She whined and whimpered until her took the bit out of her mouth, and then gulped down her saliva to start begging. "Please, Master, can I have some cum? Please? Please, Master?"

He blinked, shocked, but he soon started to smile. He held her steady as she lowered herself to her knees, and dutifully took out his cock. Sakura inhaled deeply, taking in the scent of the hard rod as her mouth salivated. She wanted this. She wanted his harsh words and his praise and his cum all over her.

Sakura wrapped her mouth around him and savoured the taste as she started to thank him for all of his hard work.

X X X

Rin swung Kanshou back and forth, watching as it was drawn towards it's twin blade in her other hand.

The sword was fake. There was no way of denying that, it was nothing like a projection. The world should be actively trying to erase it right now, but it wasn't. The same was true of the erotic clothing she was wearing. The maid outfits she had made for herself and Sakura yesterday were still around as well, with no sign of disappearing.

It was a good thing, but it frustrated her because she didn't understand it. There was something about her Noble Phantasm that was still a mystery to her. That shouldn't have been possible for a Servant with a Master, but for some reason it was.

She sighed. She was no closer to figuring this out.

As far as Rin knew, she couldn't produce any weapon strong enough to blow through Berserker's ice shield. That was an A-ranked Noble Phantasm, which was the highest attack strength she could reach with a Broken Phantasm. To get through it they would need something ranked A+.

Something like... Sakura's Noble Phantasm. Which she didn't have the magical energy to use.

That didn't mean there was no way to make it happen. Just that Rin needed to work out how it was going to be done.

Silently, Rin made her way over to the dojo. Her Master and her sister were inside, and she needed to talk to them about –

She swung the door open, and balked in surprise as she saw Sakura on her knees, eagerly sucking Master off. Sakura was constrained by her own Noble Phantasm, with her arms bound behind her back, and her body was marked all over with long red welts that looked like tiny scars. And she was eagerly, over-enthusiastically, forcing their Master's cock down her throat as deeply as she could.

Rin hesitated. The sensible part of her mind was telling her to run away, right now, before she got sucked into this. But her own backside was still red and stinging, and she hadn't been able to forget how easily she had been forced to orgasm earlier in the day. Despite having reached that high once, her body still craved mistreatment.

Maybe if she was really really quiet, this time Sakura wouldn't notice her.

Rin's hand found it's way between her legs, probing against her own inner walls as she hid her moans as best as she could.

They would have a strategy talk soon. They'd all earned a little fun, hadn't they?

So there was always going to be a Shirou "punishing" Sakura scene at this point in the story, but somebody over on QQ pointed out that Sakura's Noble Phantasm was the perfect opportunity and well... I couldn't resist.

I genuinely debated with myself for about 15 minutes regarding if either Shirou or Sakura should know the term "pet play" or not. I like to think that they're just stumbling through this BDSM thing, not actually knowhing what's safe or not, so I decided to have them just do something similar without strictly understanding why they both thought it was so hot.
