Lying on the bed was Kocho Shinobu, dressed in thin pajamas.
The blanket was pulled back, and at Akira's voice, she slowly raised her head. Her purple eyes, reflecting the moonlight, glistened as if wet.
"...You're late, Akira-san."
"Why are you here? More importantly, why aren't you sleeping?"
Akira asked in confusion, but instead of answering, Shinobu slowly lowered the blanket.
Her defenseless appearance revealed her cleavage starkly. The lines of her collarbone and shoulders, and the curves of her breasts—which, while still retaining a girlish quality, were large for her age—were exposed unabashedly.
"Were you... good with my sister?"
Shinobu's voice was calm, but it held an undeniable heat and jealousy.
"Shinobu, that's..."
"Don't even think of lying. I came here knowing everything."
Shinobu got up from her spot and sat on the edge of the bed. Then, a strangely sweet and dizzying scent wafted into Akira's nose.
"...This smell?"
"Did you notice?"
Shinobu smiled seductively and traced her neck and collarbone with her finger.
"It's Wisteria poison."
"What?!"
Akira tried to step back in alarm.
Wisteria, and the poison made from it, is a deadly venom for demons. But strangely, instead of paralysis or pain, a hot heat was rising from his lower abdomen.
His heart pounded as if it would burst, his reason grew hazy. His legs felt weak, as if he would collapse.
"Don't worry. It's not a lethal poison."
Shinobu whispered in a languid voice.
"I specially modified the composition to work on a demon like you, Akira-san, who's an exception. I removed the toxicity... and left only the components that stimulate nerves to amplify excitement and pleasure. It's a kind of demon-specific aphrodisiac, you could say."
She had applied the drug in advance to her neck, cleavage, and inner thighs. The aphrodisiac components were entering his respiratory system, melting his brain.
"Shinobu... you...!"
"You can say it's underhanded, but I have no choice. You only dote on Mitsuri-san and my sister... and treat me like a child. If I don't do this, you won't hold me, will you, Akira-san?"
Akira's eyes gradually lost focus. The drug was starting to take effect. His resistance was weakened from the fatigue after his time with Kanae.
While Akira staggered, Shinobu pulled him onto the bed. Akira, having lost even the strength to resist, fell onto the bed.
"Stay still. I'll have my way with you tonight."
Shinobu nimbly climbed on top of Akira's hips. She knelt on his pelvis and looked down at him.
Her face was shadowed in backlight, but her purple eyes glimmered with desire.
Slurp~
She loosened her pajamas. The pajamas slid down to her waist, fully revealing her pale upper body.
On her white skin gleaming in the moonlight, the aphrodisiac she had applied shone with a glossy luster.
"Look closely, Akira-san. I am... a woman no less than my sister."
Shinobu leaned forward and pressed her breasts against Akira's face. Her elastic breasts, similar in fullness to Kanae's, touched his lips.
"This smell, hard to resist, isn't it? If you want... you can lick it."
Akira instinctively opened his mouth. In his brain-numbed state, the sweet scent before him was an irresistible temptation.
He stuck out his tongue and licked the aphrodisiac applied to Shinobu's collarbone and cleavage.
"Hnggh...!"
A moan escaped Shinobu's mouth. Each time Akira's rough tongue brushed her skin, she too trembled in pleasure.
Even though she had made the drug, its effects were on her as well.
Although it works on demons, since it contains aphrodisiac components, it had a faint effect on Shinobu as well, albeit weaker than on Akira.
"Haa... haa... more... more...♡"
After receiving enough caresses, Shinobu prepared to move on to the main event.
She lifted her hips slightly, then grabbed Akira's hardened member with one hand.
"Kuhuhu. It's gotten huge. My drug, it must be effective, huh?"
With trembling hands, she aligned the tip of the club-like member with her wet entrance. Her inner thighs trembled with tension.
"Akira-san... please come in...♡"
Thud thud.
"Ahyuk...!"
As Shinobu applied her weight and slowly lowered herself, a sound of tight inner walls being forcibly spread was heard.
At the pain of her first experience, Shinobu's brow furrowed and tears welled in her eyes. But she didn't stop.
"Hng... uu...!"
She tightly gripped Akira's shoulders, enduring the pain, and lowered her hips all the way down.
When she finally succeeded in swallowing him to the root, she took a rough breath.
"Haa... haa...♡ Now, you're mine♡"
After catching her breath for a moment, Shinobu slowly began to move her waist. The expression that had been pained gradually turned hazy with pleasure.
"Hng...♡! Akira-san...! Ugh♡!"
Squelch. Squelch.
Explicit friction sounds filled the room. Shinobu placed her hands on Akira's stomach and began moving up and down vigorously.
Akira, intoxicated by the aphrodisiac, also thrust his hips up in time with her movements.
"Aah! Ah! There...♡! Hng♡!"
Shinobu's small body shook in response to Akira's violent movements.
Her sweat-drenched hair stuck to her face, and saliva dripped from her mouth. Her usual elegant and cool demeanor was gone, leaving only the instinct of a female craving a male.
"Aah♡ Akira-san...! Ugh♡! It's good...! More, drink more of me... my poison...♡"
Her breasts swayed with each movement, her skin wet with sweat and the aphrodisiac, and her eyes hazy with pleasure.
Akira was so captivated by her beauty that he lost himself gazing at her.
"Don't think about my sister... hng♡! Right now... look only at me...♡!"
Shinobu cupped Akira's cheeks and forced him to look into her eyes.
"How is it inside me? Does it tighten more than my sister's? Is it... hotter♡?"
She constantly wanted confirmation. Instead of answering, Akira tightly held her hips and thrust into her roughly like a beast.
"Kyaaah♡!!"
At the intense stimulation, Shinobu threw her head back and screamed. Her body arched like a bow, as if a butterfly were flapping its wings.
All night long, the butterfly danced on the flower. The poison she had made, Akira's technique, and Shinobu's innate vitality deeply plunged the two into a swamp of pleasure, and in that swamp, Shinobu finally became Akira's complete woman.
After several hours of the deed ended.
"Shinobu. How did you make that aphrodisiac? Even if you mixed it well, you'd have to test it, right?"
"I did it with Mukago and Ubume-san."
"Oof."
The two who had become test subjects for the aphrodisiac were somewhat pitiful. Especially since Mukago was, along with Kanao, the only girl in this house he hadn't touched.
He had brought her purely because she was cute and her voice was to his liking, feeling no lust at all.
Moreover, since their relationship was still awkward like a squad leader and a difficult soldier, there was no sign of that happening.
"Hey, Akira-san."
"What, Shinobu."
"Um, well. Did I seem too much like a loose woman? Was I... a bit ugly?"
"If a woman like you is ugly, then every woman in this world would be ugly."
Shinobu's reaction reminded him of when he was assaulted by Kiyohime and had his first experience. Memories came back, and since he grew up under them, Shinobu's resemblance to them felt endearing.
"Hehe. So, I'm your woman now, right? Well, not legally, but practically one of your wives, right?"
"I'm a man who takes responsibility. With Ubume and Tsubaki, even if they're not lovers, I promised to take care of them for life."
"I'm a wife, right? Me."
"You are. Why, are you anxious?"
"Just, I was worried I might end up just a mistress. I was anxious."
Shinobu was anxious that it might end as just an enjoyment relationship, like the examples of Ubume and Tsubaki. She was still young, it seemed. Akira patted Shinobu's head and hugged her.
"Don't worry. I'll take responsibility for you. Your position is different from theirs, right?"
"That's a relief. I'm reassured that Akira-san will take responsibility."
"...Shall we do it once more?"
"Huh? Ah, my hips still hurt..."
"If you don't want to, I won't. I don't force things."
At Akira's words, Shinobu grabbed his wrist and brought it between her thighs.
"I, I didn't say I didn't want to."
Thus, they spent another hour or so of hot time, and that morning.
"Eh!? You two also became Akira-san's wives!?"
The Kocho sisters didn't hide it and immediately told everyone the fact.
"I expected it, but well done? Shinobu."
"Ah, you knew, sister."
Kanae had seen Shinobu going somewhere in the middle of the night and thought she was going for a night visit. Being sisters, their thoughts were probably similar.
She was just happy that Akira accepted her without refusal. And the most surprised was Mitsuri upon hearing the news.
What the two were worried about was, of course, Mitsuri's reaction.
Even though they were rivals, she was too pure and good a person, so they were worried she might get hurt, but.
"Wow~! Then, with Kanae-nee and Shinobu-chan, we're really family now! I'm super happy!"
Mitsuri was a more naive girl than imagined. Rather, Mitsuri hugged the two and said she was happy.
At her reaction, the butterfly sisters were flustered with an expression of not expecting it again. But they accepted it as all's well that ends well.
And the Servants who heard the story also seemed to approve, since it was the Kocho sisters and not some other woman. Rather than showing rejection like with Mitsuri, they had known them for a long time and raised them, so they acknowledged it.
On the other hand, what they were concerned about was Kanao.
Although only two years younger than Shinobu, she was still the youngest in the house, unaware of worldly affairs. Born into abuse from her parents, sold as a slave, she lived an unfortunate life.
Just when she seemed to find happiness in a peaceful home, in such a situation, the butterfly sisters she looked up to like sisters became the lover of her adoptive father Akira. They were watching her reaction a bit, but.
With a mindset of not caring about such things, Nobbu cracked a joke while chewing on senbei.
"Must be nice having more moms, Kanao."
At her joke, everyone looked at Nobbu in shock, and the Kocho sisters couldn't look at Kanao as if feeling guilty, but.
"Yes, I think it's good."
"Huh?"
At Kanao's following response, Nobbu, who made the comment, was the most flustered.
"Th-that, isn't it shocking or something? Your dad added more women? And he touched girls not much older than you?"
"...I don't really know what's wrong with it. But, if everyone lives harmoniously like this. Isn't it good?"
"Kanao, ugh! I'm sorry for being a bad adult!"
Kanao, purely saying that if everyone is happy, it's good. At her pure light, Nobbu apologized to Kanao instead. Of course, Okita dragged Nobbu away to beat her up for making an inappropriate joke in the first place.
For Kanao, who had always lived only in unfortunate and broken homes, as long as everyone in this household lived harmoniously. That alone was good.
Thus, a few days later. During that time, with the Kocho sisters added and new women increasing, the existing women craved Akira's body even more.
Thanks to that, even with care, Akira became thin as if losing weight and lost energy.
Anyway, the moving preparations were finished. Tamamo burned a talisman and chanted a spell.
"Then, I'll erase the traces."
Whoosh~
The mansion in Ginza wavered like a mirage and instantly disappeared.
Only overgrown weeds remained as if nothing had ever been there. No matter how much the Demon Slayer Corps searched this place, they wouldn't find a single speck of dust.
Akira and his party packed their luggage and boarded the carriage. Their new destination was Asakusa, Tokyo's largest bustling district.
Inside the rattling carriage. Kanae and Shinobu were sitting tightly pressed against Akira's sides.
Mitsuri watched that enviously from across and ate her lunch box.
"Shinobu, you look good?"
When Kanae asked with a meaningful smile, Shinobu hugged Akira's arm tightly and answered coyly.
On her neck, faint red marks left by Akira last night remained.
"I wonder. Sister... your skin seems to have improved, doesn't it?"
At the sisters' subtle boasting, Akira sweated coldly and looked out the window. With his karma growing, he wondered if he might die from exhaustion despite being a demon.
As the carriage approached near Senso-ji, a tremendous crowd was seen. Nakamise Street was packed with worshippers and merchants, with no room to step.
"Wow~! There are so many people! Delicious smells!"
Mitsuri pressed her face against the window and shouted.
The carriage passed through the bustling district and turned into a slightly quiet but conveniently located residential area. The carriage stopped in front of an ordinary-looking two-story wooden house.
"We've arrived, Master."
Where Tamamo pointed with her fan. Akira's pre-viewed, and Tamamo-renovated new hideout.
"From the outside, it looks ordinary, but inside, space expansion spells are cast, so it should be wider than the previous mansion. And with powerful barriers set up, our presence is completely blocked."
"Well done, Tamamo."
The party who entered inside marveled. Unlike from the outside, the interior was as wide as a playground, with the latest Western furniture and Japanese tatami rooms in harmony.
"Hoh, quite cozy. Where's the liquor storage?"
Shuten Douji first ran off to find the liquor storage.
"The kitchen is wide too, thank goodness, chirp!"
Benienma checked the kitchen with satisfaction.
Hokusai (Oei) dashed off to see her studio first, and everyone headed to their respective rooms.
Akira opened the window of his room on the second floor. In the distance, the red five-story pagoda of Senso-ji and its brilliant lights were visible. The noise of the crowd faintly reached him.
'Asakusa... this is our new stage.'
It's darkest under the lampstand. This densely populated area was the optimal place to hide demons and the center of information.
Now, what remained was to find Tamayo hiding somewhere here. And to grasp the动向 of the Demon Slayer Corps, who would start moving after receiving Uzui Tengen's report.
