"Do you have any plans for tomorrow?"
On the day he returned from an expedition, stripping off his soil-stained haori, Giyuu was asked this by Shinobu, who wore her usual gentle smile.
It was a mundane conversation that didn't feel out of place at all. However, for the two of them, it served as a secret signal announcing the start of a hidden night.
"None."
With that short reply, she came to his bed soundlessly that night.
Since when had they fallen into such a strange and distorted relationship? Even if he tried to trace the beginning, fragments of memories blurred by heat got in the way, and he couldn't remember clearly.
When he welcomed her into his sleeping quarters, it wasn't long before a soft weight rested on his chest.
".....Fufu."
Slender fingertips touched the nape of his neck. Burying her face against his chest, her soft hair danced against his skin. As he narrowed his eyes at the tickling sensation, he felt her presence, acting like a child and acting spoiled in a way one could never imagine from her usual dignified demeanor.
'I wonder if this person is truly Tomioka-san. Having become honest with his desires, he's quite cute compared to his usual self.'
Every time her hair swayed, the scent characteristic of a man and a faint smell of sweat hit her nostrils. As if cherishing it, Shinobu gently wrapped her slender arms around his face at her chest.
"Hey, Tomioka-san. Why don't you usually get along with me? Doing this.... It shows you.... really love me, doesn't it?"
She tried throwing out the question in a voice tinged with a bit of sadness, but the only response was the sound of rustling clothes.
Instead of giving an answer, Giyuu persistently dropped kisses from her white neckline to her exposed, ample chest. His lips, maintaining silence, were more passionate than words as they feasted on her skin.
No matter how roughly or lewdly she was treated, this woman wouldn't ever break her iron mask for a while. Suppressing the urge to strip away that composure, he simply layered his caresses as if enduring patiently. He wanted to see that refined face warp with pleasure soon. However, he also knew she wouldn't crumble so easily.
"Shinobu."
He tried whispering her name into her ear.
When he did, he felt her laugh softly and airily, as if it tickled.
At this moment, the two of them were incredibly calm. Even though their upper garments were greatly disheveled and their skin was pressed together, there wasn't even a sign of their cheeks flushing. Though the act had already begun, the two of them carried a quiet, detached air, as if it were someone else's business.
"Tomioka-san, do you like my chest that much?"
".....I think any man would."
"Is that so? Fufu, does that mean all the men in the world are perverts? How lewd."
"That's why you should be careful. No matter how strong you are, if your poison and sword are taken away, you're no match for a man in terms of strength. If you let your guard down, you never know when or where you might be attacked."
"How unpleasant. Don't you look down on me a bit too much?"
With a giggle, Shinobu reached out without hesitation and firmly gripped Giyuu's vitals.
"Ngh...!"
Giyuu’s face warped with a heat that resembled agony.
Even though he had gone through the trouble of warning her, this woman....
"I really love that kind of face on you, Tomioka-san."
"Even though you.... usually hate it... ngh."
'Ah.... you really are lovely, Tomioka-san.'
Shinobu raised the corners of her mouth mysteriously, then gradually loosened her grip, wrapping her hand around him as if to cherish and stroke him. Giyuu, too, didn't stop the movement of his hand as he fumbled with Shinobu's chest.
For now, just for now, they would become slaves to this sweet pleasure.
By now, negative emotions like "hate" had been pushed to the far depths of their brains. No, rather, their minds were now being filled with an indescribable affection.
Without knowing who initiated it, they brought their faces close and overlapped their lips.
After a few small, pecking kisses, they deeply entwined their tongues. He felt the heat transmitted from their pressed skin gradually pushing up their respective body temperatures, and their breathing grew heavy.
"It’s gotten a bit hot, hasn't it...?"
Shinobu whispered slowly in a dream-like voice.
"I suppose being stroked by, you, Tomioka-san has improved my circulation quite a bit."
She laughed without losing her composure, but her eyes were already moist and unfocused. Her hands, tracing his cheeks and back, seemed to plead silently for something hot soon.
"....Is it time?"
Giyuu quietly reached out his hand and slid his fingers toward her most secret place, which was already overflowing with nectar.
"Ah...!"
Instantly covering her mouth with both hands, Shinobu let out a pained voice. Her soft thighs wrapped around his right hand as if not to let it escape.
"...Don't close your legs."
Commanding her in a low voice, he grabbed her slender legs with his left hand and forced them open to the left and right.
As he applied his right hand to the wet spot and moved his fingers slowly, he stared intently at her. Perhaps unable to bear the shame, a weak, pleading voice came back: "Please.... stop...."
He wondered if this was her weak point. While feeling certain, he slid one finger smoothly inside.
Along with the sensation of pushing through the hot mucous membrane, a small cry of pleasure arose.
First, he slowly loosened the inside that tried to close tightly with his middle finger, followed by his index finger, going deep. Shinobu gripped the sheets tightly with her fingertips and continued to cry out as her body writhed against the irresistible pleasure.
"Ah... ah... Tomioka-san... already... ngh."
Before she knew it, her eyes were filled with tears. Her white, slender legs bounced and trembled from the waves of pleasure.
"Please.... do it...already.... Tomioka-san...."
At this moment, unlike her usual self, she didn't tell lies or nonsense. With melted eyes, she looked straight at Giyuu and whispered her desires exactly as they were.
'....I'm weak against those eyes.'
Slowly withdrawing his fingers, he pinned her body down as if to cover her.
Her expression was now colored with a look of intense longing and ecstasy.
"....Don't conceive."
"What a joke..."
That was something left to heaven.
He placed his member against the trembling entrance and pushed against it to confirm its hot shape.
He made Shinobu's legs, which were about to close, spread wide again. Perhaps ashamed, she tried to cover her face with her hands again. Giyuu thought that if her left hand opened, he would peel it away.
Slowly, as if descending a staircase one step at a time, he inserted himself inside.
Along with that, from Shinobu's lips, intermittent voices like "ah.... aah..." began to leak.
It felt a bit tight, but he pushed even further. He let himself drown within that abyss soaked with nectar.
He reached the very depth.
Since Shinobu wore a pained expression and was desperately trying to catch her breath, he stopped moving for a moment and stroked her head to soothe her.
"Tomioka... sa... n."
She weakly extended her arms and hugged Giyuu's head tightly as if to embrace it. In response, Giyuu also pulled her fragile back close.
"....Does it hurt?"
When he asked secretly in her ear, Shinobu gave a short nod saying "It's fine" and returned a kiss. For a while, they simply repeated kisses in silence. Just overlapping lips, just pecking gently, and then entwining tongues greedily. As if confirming and tasting each other's existence.
These lips, which usually spat out thorny words like poison, were now the opposite, soft and faintly warm.
Soon, he began to move his hips slowly.
According to a steady rhythm, she cried "ah, ah" in small intervals yet again. In conjunction with that movement, her ample chest also swayed as if dancing.
Even though she was such a hateful woman, right now, she was unbearably precious. While looking at Shinobu's white limbs, Giyuu was immersed in an indescribable deep emotion.
'....I wish time would stop like this.'
Even such an uncharacteristic wish crossed his mind.
Every time he thrust his hips, her alluring voice echoed through the silence of the night.
"Ah.... Tomi.... oka.... sa... it feels.... good.... ngh."
It seemed that even this woman had no choice but to become honest once it reached this point.
Her hand, which had been around his neck, moved to his cheek, and his face was wrapped in both of her hands.
Their gazes met head-on.
".....Don't look."
"Fufu.... It's rare, so I'll look."
With a happy, somewhat radiant expression, Shinobu continued to let him thrust deep while she stroked his cheek.
Next, he turned Shinobu over and thrust deeply from behind.
Perhaps this position stimulated her even deeper. Her breathing was clearly more labored than before, and her cries were higher and more intense. Her back, arched like a bow, was illuminated by the moonlight shining through the window, appearing translucently white.
Giyuu himself was almost drowning in the waves of approaching, intense pleasure.
His heartbeat throbbed at an almost eerie rate, and he became desperate to spit out all the heat accumulated within him right away.
But.....
....Just a little more. He wanted to savor this sensation for just a little longer.
'I don't know when the next time we can do something like this will be. Perhaps we may never meet again. That's how severe the coming battles will be.'
'Both I and Tomioka-san could die at any moment. ....Well, this person doesn't seem like he would die easily. But in the unlikely event he were to die, losing him would be somewhat of a waste.'
'Losing this woman would be a waste. I thought I neither particularly liked nor hated her, but our compatibility in overlapping our bodies like this is surprisingly good. Even in battle, being able to entrust my back to her is reliable.'
'She also has a cuteness that makes me want to accidentally stab her while she's letting her guard down around me. Until now, the people I've met either praised me to the heavens or were afraid and kept their distance. A person like her is rare. It would be a bit of a waste to lose her.'
Contrary to her expression, her words were sometimes like a sharp blade, but that was just how the woman was. She wasn't forcing herself to act tough. It was a natural strength she was born with.
Once again, they faced each other and held each other firmly.
Shinobu's legs were shaking slightly, and it seemed she didn't even have the strength left to brace herself.
A single bead of sweat trickled down from Giyuu's forehead.
It was already the limit.
"Shinobu.... I'm coming out."
"Ah... ngh.... ye.... s.... ngh."
In a raspy, wordless voice, Shinobu certainly replied.
They gripped each other's joined hands as if they might break.
"....!!! "
"....Ngh!!! "
The two of them climbed to the peak of climax simultaneously. Giyuu's body stiffened, and he spat out a hot mass into her depths.
From the joined parts, they felt each other's life throbbing and pulsing.
After spitting everything out and slowly withdrawing himself from her, Giyuu rolled over to the side as if exhausted.
'....Not bad.'
Thinking that, both of them drew close to each other and closed their heavy eyelids.
Sleeping side by side like this until the morning sun rose had become their secret rule.
