There are only minor hints of Monoyoshi/Gotou.
3.
Every sword belonging to Sen and Rinko sat in the Ashina Citadel's great hall. The sages sat atop the dais.
Currently, Sen was reading off a piece of paper, listing the accomplishments her household achieved this year.
Rinko originally pitched the idea to celebrate their second year as saniwas together in her citadel. She wore a pink kimono and had touched up her hair and face for the occasion. Her clothes and hair pieces had flower motifs to fit the spring season. Sen, however, wore her usual sage attire. Rinko bit her tongue to prevent yawning.
For entertainment, her eyes wandered over Sen's swords. It was an unspoken rule that saniwa shouldn't sleep with swords from a different citadel. They should never have to grapple with their loyalty, which belonged solely to their master. Rinko, nonetheless, indulged by looking at them. She glossed over the tantous and wakizashis and settled on the uchigatanas. Mutsunokami was listening attentively.
She first saw him a week after Sen and Rinko manifested their first swords. Sen brought Mutsunokami, Sayo, and Gokotai to Rinko's home to meet Kashuu, Aizen, and Imanotsurugi. Mutsunokami had everything that Sen ogled. When they apprenticed and lived in the same shrine, Rinko had went to Sen's room to borrow a book. When she opened the item, clippings of well-muscled men fluttered down like leaves in autumn. Rinko had a good long laugh that night. She had finally found evidence of Sen's lust.
Sen and Mutsunokami were going to fuck eventually, Rinko knew. Gossip confirmed it, as far as she was concerned. Sen finally had a man she could trust with all her confidence and most personal thoughts. And yet, during the feast last night, Sen was eating her meal in peace while Hirano poured her tea. Rinko, on the other hand, leaned against Shokudaikiri and rubbed his thigh. Some of Sen's swords side-eyed Rinko. Her tantous knew better than to ask any questions, but some huddled together, whispering about Rinko. Sen's swords would know that displaying affection was normal, if she stopped being a covert pervert.
Rinko gazed over the other uchigatanas, until she met a pair of red eyes staring back at her.
Sengo winked at her. Rinko raised an eyebrow. Did he know what she was thinking?
1.
Sengo stood facing the shoji of his master's study. He knocked on the wood.
"Who is it?" his master's voice came from inside.
Tonbokiri, after Sengo manifested, had mentioned that their master was a woman; that would make for great entertainment.
"This is Sengo Muramasa. I'm the so called demon blade."
"Please, come in."
He slid open the shoji. She was more lovely than he had imagined. She had long black hair and fair skin. She wore the modest white and red saniwa garb. He wondered what wonderful things she hid under her clothes. Beauty was wasted if it was never seen.
"I am Ueda Sen," she smiled and nodded. "As the head of this citadel, I welcome you."
Sen, he chuckled and knelt, facing her. "We share the same character in our names."
"Yes, my mother had given that to me...," her eyes glimmered with a touch of nostalgia. "If there is anything you want or need to know, please ask me or anyone else."
"I have two questions," Sengo crawled closer to her.
Her expression changed to confusion. She was so innocent; Sengo would have to teach her the benefits of being wicked. His face was inches away from hers.
He tugged at the collar of his attire, revealing skin. She stared at his exposed chest.
"What are you thinking about, Master? Shall I undress?" having this form would let him explore the full pleasures of the human body. This woman, his master, would be the first he would share these sensations with.
Sen said nothing. Perhaps she needed some coaxing. Who knew what hesitations or fears she absorbed about sex. She had to learn to let go of those silly morals. He raised a hand towards her face, ready to touch her chin.
"...Muramasa."
"Yes?" he stilled his hand.
"You must return to your rooms. You will be participating in chores tomorrow," her face showed no fear or disdain. She had faced much more fearsome monsters than him.
His lips twitched. Sengo pressed his hand against the tatami mat. So, she was uninterested, but he would enchant her soon.
"As you wish, Master," Sengo shifted away from her and bowed.
4.
Swords and saniwas were out in the gardens this morning to view the sakura blooms. Gotou, Sen's attendant, held her hand and led her about, pointing at one tree and then another.
Rinko sat with Monoyoshi under one of the trees. Sen had inherited the Awataguchi clan, fortunately. Rinko could never handle tending to so much children in her home.
"Master," Monoyoshi leaned towards her. "Someone is approaching us."
Sengo was walking towards them. Rinko knew what he wanted from her. She would give him the chance to get to know her.
"Leave me for now," she said. "Spread your luck amongst everyone."
Monoyoshi excused himself and left her. He went off to speak to Sen and Gotou.
"Ashina-sama," Sengo stood a few feet away from her. He was grinning, but Rinko didn't return any pleasantries.
"Hello," Rinko said. "How are you adjusting to your new form?"
"It's a wondrous experience," he swayed his hips. Sengo's habits were well known about the town. Rather than talk about sex, she would see how he addressed personal subjects.
"I have heard that you Muramasa blades have driven your wielders mad. Something about your smith polluting his works."
"Hm, if you wish to believe in a myth, then you can," his smile invited her eyes to wander. His top garment hugged around him, showing his bulging chest. His arms were bare for everyone to see. "Shall I undress and let you judge me?"
He tugged the side of his hakama. Sakura petals rained down on them. Rinko had no hesitations about bedding Sengo, but he didn't belong to her.
"You can die trying to strip here," Sen would dismantle Muramasa if she was angered enough. In truth, death was better; it implied that you had lived. You could leave something behind in this world. Dismantling would make your whole body disappear. "I want to fully examine your beauty, but will that upset your master?"
"Should it matter? These unspoken rules you humans follow restrain yourselves from living a full life."
The life of a lawless demon was an envious thing. He did as he liked and had no worry about reputation or upholding family honour. Had Sengo been born human originally, he would understand the perils of walking about this land.
"That is very true, Muramasa. I know what we can do to rectify this complicated existence."
5.
"This is a good place," Rinko opened the shoji. The room was furnished in a Western style, with chairs, a couch, and a study table. She stepped into the room and stood a top a chair. "It was made in case we received foreign guests, but it has been barely used and is down an empty hallway."
"What have you done in here?" Sengo closed the shoji and walked to her. They were inches away from touching. He wanted to know how bad she was. She had a little smile on her face.
"Kogitsunemaru and I roleplayed. I was an unsatisfied imperial wife who was spirited away to an unknown place. He was a fox god who mated with me all day and night until I was carrying his cubs in me."
"My, what a wanton woman you are," her story was already making him hard. He nuzzled his face against her chest, feeling small breasts. He smelled orange perfume on her. Were her swords conditioned to be aroused when they smelled that scent? "You're utterly fearless."
"We Ashinas are descended from a goddess," she ran her hands through his pink hair. "I have divine blood. Demons do not worry me; they should fear me."
"They are whatever you make of them," he kissed her exposed neck. "They only have power if you believe in them. What do you think about cursed swords?"
Rinko kissed his cheek and then his lips. He opened his mouth, so the tip of their tongues could touch. The were only teasing each other. The main event was yet to come.
"I want to know if you can fuck as well as a blessed one."
"I'll let you decide," it was good fortune to have found this lady so in tune with him. If Sen was uninterested in him, then so be it.
He wrapped his arms around Rinko's waist and carried her.
Rinko giggled as he set her down on the table. Her hands felt his hard arm muscles. She wanted to pour honey on him and see his skin glisten. Seeing him lick the substance off of him would make for a good show. Next time, food would be involved. Sengo never objected to any sexual act.
Sengo tugged at the back of her obi. Rinko raised an eyebrow. He knew how to undress a lady? He must have learned how to do it from past encounters with people, but who were they? Sen rarely dressed up.
"You may undo my sash. Now, tell me," her palms pressed against his chest. Her finger circled his nipple. "Whom have you made love to?"
A single laugh escaped his lips.
"As many who are willing," he smiled and untied her obi.
"Is your master one of them?"
Sengo paused. Perhaps it hurt his pride to be asked or maybe he was planning to deny any relations with Sen. Rinko already knew the answer, though she just wanted to know if Sen had done anything risky.
"Sorry," she withdrew her hands. "I should not have -"
"No, it's fine," he pulled her sash off. Sen had a criteria for lovers that he couldn't meet. "She can bed whomever she pleases."
"She is very careful," Rinko lie against the table surface. "But that is enough about her. We are all about each other now."
Sengo parted her kimono. The cool air made her shiver.
"I shall warm you up," he pressed a palm against her bra. He massaged her breasts in circles, pressing on the places women liked.
Rinko arched her back as he made his ministrations. Her pleasure washed over her body as he squeezed her. She wrapped her legs around his waist and pulled him close to her.
"What's the matter?" he smiled wickedly. His hands gripped her hips and he grinded his erection against her.
This snake will not get the better of me, she thought. She was the heir of a powerful clan; a mere sword couldn't undo her. "I was with Nikkari and Kikkou once. They took turns pleasuring me with their mouths to decide who was the better performer."
"Who was the victor?" he ran his thumb up and down her clothed nub.
"I-it was a draw; they both made me come twice."
He slipped her panties off. Hopefully, he would outdo Kikkou and Nikkari. Perhaps all three of them could have Rinko at the same time.
"A woman's body is an enviable thing."
When Rinko and Sen apprenticed together, they occasionally bathed in an onsen. Sen got taller, her curves formed, and her breasts grew out. Rinko, two years Sen's junior, hoped she would mature soon, but she grew only a little bit and was near flat chested. She supposed that the gods punished her for being too confident about everything else in her life. Regardless, Rinko's lack of physical endowments forced her to be brave against imposing people.
Sengo lowered himself and kissed the hair between her legs. He licked downwards until his lips pressed against her entrance.
Rinko pressed her thighs against his head. She felt his tongue slip inside of her. Rinko grabbed his hair and pressed him against her nether regions. He was only permitted into this room to satisfy her and she damn well reminded him of that fact. She felt him grinning against her skin.
Sengo sucked up her wetness. His tongue slithered inside of her, finding all the right places. His thumb circled her nub, increasing Rinko's pleasure. Her body already tensed up and her breathing quickened.
Fucking a sage was something else compared to being with another human. There was this overwhelming need to serve the saniwas well and forever, until one's spirit was spent. No sword could resist loving his master the moment he met her. What would it be like to have the sages at the same time?
Rinko gripped his hair then. She cried out and clenched around his tongue. Her liquids poured into his mouth and he lapped up every drop. She tasted tangy, like so many others.
He listened to her catch her breath as he licked the wetness seeping out of her. A minute later, her thighs went limp and he was released. So, this was how powerful women could be undone. Sengo would remember where he touched her to bring her to ecstasy for next time.
Rinko was exhausted, but she kept her eyes on him.
"We're only half way to the end, Ashina-sama," Sengo untied his hakama. He took his erection out for her viewing.
Oh, he was big. While Sengo stroked himself, his member enlarged and the veins thickened. This excited Sengo the most; seeing his partner captivated by his performance, being the centre of attention. He only wanted to have sex more and more. Why did humans hesitate so much when it came to carnal desires?
"What do you want me to do?" he pressed the side of his cock against her thigh. He rubbed his tip up and down along her skin, smearing his precum on her.
Rinko knew they would meet each other in secret again; a room could be rented or he could sneak into her citadel. Right now, she could request anything from him.
"Come on me," she pointed at her belly. "I want to see how much I can milk out of you."
"As you wish," Sengo quickened his pace. He grunted as his cock pulsed within his grasp. He would show her what he was made of. Then, he climaxed and came over her. His seed splattered out and streamed down her skin. Rinko gasped as she felt his semen spread about her in streaks. There was much more seed than expected.
Sengo leaned forward and pressed his hands on the table. She watched the demon pant. His sweaty, heaving chest was a wonderful view. He still had that lustful look in his half-lidded eyes. They had plenty of hours left to fool around. He was going to clean off the mess he made.
Sengo, in my eyes, is the type of person that challenges what is considered acceptable in society. He will do as he likes, unafraid of conforming to norms.
