Noah appeared in the seventh squad dormitory's living room. Himari, Shushu, Kyouka Nei were all present, pying a game of monopoly.
"I'm back." smiled Noah.
"Onii-chan." smiled Nei gently.
"Welcome back, Noah. Take Himari and go to this training trip of yours." replied Kyouka.
"I'm still waiting for that massage, Noah." said Shushu, making Noah pause.
"Damn, sorry, I keep deying. How about Saturday after Himari's duel? To make up for the time you waited, I'll make it an extra-long and luxurious one." As an apology, Noah would give her a full body massage, from the top of her scalp to the tip of her toes, excepted for the front parts.
"That's a deal!" grinned Shushu.
"Can I get one, too? Asked Nei, hopeful.
"Sure, after Shushu." In Nei case, he would limit things to twenty minutes or so on her shoulders and back, without activating hands of Nirvana.
Himari took a backpack she had prepared in advance.
"I'm ready." she said to Noah.
Noah took her hand and turned to the others.
"We will still be ready to act if anything happens, so do not hesitate to contact us. See you ter, everyone."
"Yes, we'll call you if we need your help. Good luck with your training." nodded Kyouka.
Noah nodded to them and teleported with Himari.
…
"Where are we?" asked Himari as she looked around. She could see that Noah had brought her inside a rge home. She could see a rge pool in the garden beyond the windows, and the furniture spoke of understated wealth.
"This is my home. Your home, eventually. There's a dozen people living there usually, but they should all be at school or doing something outside."
"It looks, nice." said Himari as she studied the room with renewed interest.
"I can show you around some other time." smiled Noah. "For now, we have limited time until the duel, so we should get started right away. Follow me, Himari."
Noah opened a door leading to descending stairs.
Himari followed him to the lowest of the two basement floors.
"This floor is divided into eight rge rooms, and two smaller ones that are obviously meant to be bathrooms, since there's a water supply and a shower stall. I'm in the process of furbishing them. The eight rooms were empty until recently, but I have started turning two of them into a bedroom, and a training room. We're going to use those."
Himari nodded, and inhaled sharply as Noah opened the door for the 'training room' and she saw what was inside. She recognized some of the furniture. A sybian. A Stain-Andrew Cross, padded with leather. A bondage bench. A cage. There were more, but she didn't know how they were named. Three of the walls contained a rge selection of leather or metal restraints, or impact tools such as floggers and paddles.
Noah entered inside and opened one of the cabinets, giving her a glimpse of the many leather or tex outfits stored inside.
Himari's breathing accelerated as she approached slowly, her eyes darting around the room. The amount of toys and restraints hanging from the walls completely dwarfed her own collection of toys.
"Himari, let's first speak about the rules."
That bought her attention.
"From this instant onward, you will refer to me as Master, or I will punish you."
"Yes, Master." said Himari, blushing.
"Good girl. You will not cum without permission. You will answer any question I ask you as honestly as you can, no matter how embarrassed the answer will make you feel."
"Yes, Master."
"Finally, you will follow my instructions to the best of your abilities." said Noah as he started undressing her. Himari stared at him as he did, lifting her legs when needed to help him.
Once he was done, Noah hugged her and gave her a slow, gentle kiss. Himari was blushing furiously as she let his tongue explore her mouth.
Noah broke the kiss and stepped back, admiring her body with a smile.
"Who do you belong to, Himari?"
"…You, Master."
"That is correct. But while your body is beautiful, I think we can improve it even further."
Noah created a leather harness for Himari, of the same type that is had used, with great results, on Asuna, Tomo and the others back then.
As he fastened the leather straps on Himari, he started to expin.
"This harness, my cute sve, has a magic property. It will stimute the growth of your breasts, while improving their shape and firmness."
"You're going to make my breasts bigger." asked Himari, her eyes widening.
"Yes. It's a slow process, adding only about one centimeter per week in bust size, from previous tests, and that is when it is worn constantly. For now, sve, I am going to have you wear it when you go to bed."
"H-How big do you intend for them to be?" She asked with trepidation.
"What is your current bust size?"
"…83D"
"…I think about 95E or F would be great. Definitely bigger, but not to the point of interfering with battle or being ridiculous… How does that make you feel, Himari? Do you like the perspective of your body being remodeled to be a perfect sex sve for your Master?"
"…I don't really know, Master." said Himari, her blush increasing further.
Noah's lie detection ability triggered, but he let it slide as he fastened the st strap.
The bck leather harness now framed her breasts, drawing attention to them, as it was intended to. But Noah wasn't nearly done with accessorizing his soon to be sve.
From the closest cabinet, he took a pair of long shoulder-length bck tex gloves and bck tex stockings.
Himari cooperated silently as he put them on her, rubbed the wrinkles out, and used a small hand towel sprayed with silicon lubricant to shine the tex, making it highly glossy.
When he was done, Noah took Himari's hand and led her to the next room, the one who had been set up as a bedroom. A rge mirror stood in one corner, and Noah pced Himari in front of it. She stared at her reflection, her mind seemingly going bnk.
"What do you see, Himari?"
"I see, myself?" she answered, unsure of what answer Noah wanted her to provide.
"That's is correct, Himari." Said Noah softly, hugging her from behind.
"You are a proud member of the Anti-demon corps, a skilled warrior, and a kind, hard-working girl, Himari. Someone I am very happy to have a retionship with. But the girl in the mirror, the horny sve girl that is eager for her Master to use her, that is also you.
Himari slowly nodded, not looking away from her obscene appearance in the mirror.
Noah was making Himari stare at herself for a reason. She already was a natural submissive, so it wouldn't take much for him to convince her to accept being his sve, but her pride was the biggest obstacle to it, and pride came from one's subconscious self-image.
What Noah wanted was to change that self-image, to tweak how Himari saw herself and integrate to it some of the elements currently sent back to her by the mirror. The image of herself, horny and wearing an obscene outfit, in the arms of her Master. All to make her more comfortable with her own desires of submission.
But one more thing was missing.
Noah closed his eyes and created another item. A bck leather colr, four centimeters wide. It had D-rings in the front and back, as well as sensitivity increasing and self-repairing magic enhancements, but also a few words engraved on the inside.
"Noah's beloved sve, Himari."
Himari inspired sharply as she saw the colr, and the words engraved inside.
"Lift your hairs, Himari." breathed Noah in her ears.
With slightly shaking hands, Himari did so, staring at him through the mirror.
Slowly, Noah lifted the colr to her neck and fastened it snuggly, making certain it didn't interfere with her breathing.
"You belong to me, Himari. Now and forever." said Noah softly.
"Yes, Master." said Himari, her tone quite different from when he had asked her earlier.
She stared again at herself in the mirror, looking entranced as she tentatively touched the colr.
"Himari, you will wear this colr a lot, from now on. Only when you shower or bath, when you fulfill your duties as a member of the Anti-Demon corps, or when you are outside, will you leave it in your room."
Himari nodded, and Noah turned her around, kissing her. After a few seconds, she returned the kiss, her tongue trying to encircle his own.
When she started getting out of breath, Noah broke the kiss, smiled, and took her in his arms, carrying her to the bed.
For their 'first' time, if Noah discounted the previous fingerings and blowjob, Noah intended to do retively normal, gentle sex. From now on, and until the weekend, he intended for Himari to have at least fourteen hours of sex and training every day, so they would have plenty of opportunities to spice things up with bondage or toys from the training room ter.
…
Himari was cuddling against Noah, luxuriating in his embrace. She felt at peace and treasured like she never had been before.
She had just offered her virginity to her Master, but the pain had quickly faded away, and the pleasure she had felt was well worth it. With one gloved hand, she touched again the colr around her neck, confirming its presence. She almost wanted to remove it to read again the words on the inside, and at the same time, she didn't want it to ever leave her neck.
She was his beloved. One of them, at least. The thought caused her heart to flutter, again.
In her family, strength was everything. Children started training right after their sixth's birthday, and were shown little affection even by their parents, unless they proved to be superiors to their siblings or nieces and nephews. She didn't even remember her mother ever telling her that she loved her.
Compared to that, what she had just experienced with Noah felt… warm. The affection in his eyes and gestures as he gave her pleasure was unmistakable, and for the first time in a long time, Himari felt loved.
Wearing his colr, staying by her Master's side… That was where she belonged, she decided. Even if it meant sharing her Master with others.
Himari shifted her position, trying to press more of her body against him, and his arms around her hugged her tighter.
"I am very happy, Master. Thank you." muttered Himari, closing her eyes in contentment. She felt him kiss her forehead.
"And I am also very happy right now, Himari, my cute sve. We have gone a long way, since our first meeting. Do you remember tsking at me for being a man?"
They both smiled at each other at the memory.
"You have offered me your heart, and I will make sure you never come to regret it… Did you know? Your training is already over. I just received a mental notification. You have accepted me as your Master, from the bottom of your heart. All that is left now is for you to sign the sve contract, and you will gain access to most of my powers."
Himari felt both incredible happiness, but also a bit of disappointment. It must have shown on her face because he ughed softly.
"However, I do not intend to end your training just yet. We have this rare opportunity where we can spend some time, just the two of us. Not the whole week like we had pnned, since it would be wrong to let Kyouka, Shushu and Nei shoulder the burden of manning the squad's dormitory longer than we have to, but I think two days would not be pushing it. And there are still plenty of things for you to learn, Himari."
Noah gently rubbed her scalp, and Himari smiled.
"Please teach me well, Master. I want to be the perfect sve for you, so that you will never leave me."
"There's no chance of that, because I am a greedy, possessive vilin. I will never let go of you… Now that you have recovered, how about we start round two?"
A blindfold appeared in his hands.
Himari smiled as she let him fasten the blindfold around her eyes. She thought that if her Master was a vilin, surely the world could use a few more vilins like him.
