After Reaching the Happy Ending, I Was Locked up by the Extremely Possessive Heroines I Had Conquered - Chapter 19.4: Interlude - The Tragedy on the Second Day of Captive Life

Chapter 19.4: Interlude – The Tragedy on the Second Day of Captive Life

Toa was followed by Satori’s turn.

The next day, Satori appeared, clutching that infamous imprisonment guidebook, a special-grade cursed object.

“Thank you, Aunt.”

She expressed her gratitude and approached with delighted eyes.

It was a good thing to convey thanks to a family member, but somehow, it gave me an ominous feeling that would not go away.

What ordeal would I face this time? I was on maximum alert when she said,

“I’ll untie your hands.”

Surprisingly, she removed the restraints from my arms. That meant both my hands and mouth were free now, which was almost complete freedom compared to the day before.

Huh? Maybe she was not so bad after all?

But my relief was short-lived.

“Imprisonment involves both the carrot and the stick. Training is important, but rewards are just as crucial. And the reward is a girl’s socks.”

“That’s just Uncle’s fetish, isn’t it!”

Aunt’s guidebook was based on her experiences when she had imprisoned Uncle.

In other words, the rewards described in the guidebook were nothing other than Uncle’s sexual preferences.

“But the book says, ‘Effective on all men.'”

“Don’t keep that kind of misleading information around!”

Both Uncle and Aunt were out of their minds. Seriously, that was why the three great families were like this.

Unfortunately, however, Satori was one of the three great families too. She looked embarrassed but also wore an expression of excitement somewhere in her features.

“It’s worth trying.”

“It’s not!”

But I had no right to refuse, and Satori gently placed the book by the bedside before looking down at her own feet.

Her gaze fell below the hem of her skirt—to her white socks.

“Hey, no way! No, anything but that…”

Satori’s face turned bright red as she fidgeted, grabbed the hem of her skirt, and lifted it slowly. Then she began to remove her socks.

She raised one foot, pointed her toes, and the fabric slid off smoothly.

“…”

That sight was so alluring, so strangely vivid, that my head felt like it was about to boil over.

It was just her taking off her socks, so why did it make my heart race like this?

“D-Don’t look!”

“You’re showing it off, aren’t you?”

“I’m not showing it off!”

Once she finished removing her socks, Satori’s cheeks flushed even redder, and she looked at me with moist eyes.

Then she thrust them toward me forcefully…

“They’re fresh off my feet from just now… Sorry, they’re new.”

“You don’t need to apologize!”

“But the book says it’s more effective after prolonged wear.”

“That’s because it’s Uncle’s fetish!”

“…Here.”

Satori thrust them at me without argument. She was bold in her action, yet her face was beet red, and she turned her head away obviously. Her behavior and attitude did not match at all.

She was forcing herself too much, even if the guidebook said so.

“Th-Thanks.”

Saying thanks seemed less awkward than taking them in silence, but it earned me a fierce glare.

“…Pervert.”

“It’s Satori’s uncle who’s the pervert!”

“Akira’s a pervert too.”

“Don’t lump me in with Uncle!”

The three great families were the only ones at fault. Please, just leave ordinary folks like me out of it.

“…Pervert.”

Satori muttered once more and averted her eyes in embarrassment.

Now, what was I supposed to do with the socks I had received?

If it were just me alone, it might be one thing, but with the person who had taken them off right in front of me, anything I did would dig my own grave.

If there were any experts out there, I desperately wanted them to teach me the correct move in this situation.

Unfortunately, though, there were no professional shogi players in this cabin who could read a hundred moves ahead. I had to break the situation with my own power.

“Can I wash them?”

“…You’re the worst.”

“So should I just smell them? Huh? That’s what you want, right?”

When I asked, Satori nodded shyly with a small jerk of her head. The book must have said so.

“…”

I felt tormented by the urge to clutch my head, but I turned my gaze back to the socks in my palm.

In addition to the soft fabric’s texture, their faint warmth meant that Satori had worn them until just moments ago.

I glanced at her alluring bare foot and swallowed hard.

They were straight off her feet, still carrying the warmth of her body. Once I became aware of that fact, my head started to spin.

“G-Go on, hurry… Smell them.”

Satori muttered while obviously flustered. She was boiling like a boiled dumpling, and the embarrassment was mutual, no doubt.

I looked back and forth between her foot and the socks once more, thinking.

If I smelled this scent, there would be no turning back.

The title of pervert who smelled a girl’s socks would surely be bestowed upon me.

But having them right in front of me like this, I felt like I could understand a pervert’s feelings just a little, if only a tiny bit.

My curiosity was inevitably aroused.

“…!”

I steeled myself and brought the socks gently to my nose.

In that instant, a faint clean scent like soap drifted over, along with a subtle warmth that lingered like Satori’s body heat and just a hint of a stuffy aroma.

My heart pounded wildly.

Whether it smelled good or bad did not matter much.

What mattered was that I was smelling a girl’s socks right now, and the girl herself was watching me do it. That fact, combined with the overwhelming sense of taboo I could not suppress, made my head feel like it was going mad.

“…Uuu…”

I heard Satori groan.

Her face grew even redder, and she gripped the hem of her skirt tightly with both hands. Her posture screamed that she could not contain her embarrassment, with tears welling at the corners of her eyes.

With eyes like that peeking at me intermittently, I would surely writhe in agony if I let my guard down.

“H-How is it…? Did it make your heart race?”

Satori asked in a trembling voice.

“…Yeah. This is dangerous.”

“Do you want to do it every day?”

“Every day would be bad for my heart.”

“Y-Yeah. This really is bad for the heart.”

We looked at each other and nodded. It was something that shaved away at both of us.

This kind of thing was fine once in a while. If we did it every day, we would truly become perverts.

After going through that hellish yet heavenly time, Mahiru’s shift arrived.

I was filled with anxiety about what ordeal would come next when

“Hm?”

Mahiru arrived empty-handed. It seemed she did not have that guidebook with her.

“Huh? What about the book?”

“It seemed bad for your education, big brother, so I sealed it away.”

“For my education?”

“Yes. That was completely adult play. At least, it’s not something high schoolers like us should do. We’re not adults—we’re babies.”

“That book was definitely too adult… but that doesn’t mean we’re babies, does it?”

“No. We’re babies.”

I did not quite understand what she meant, but if Mahiru said so, it must have been true.

“By the way, what do you mean by sealed it away?”

“I gave it back to Satori’s uncle.”

“I see.”

It had returned to its original owner. Then Satori could not complain.

“Still, I’m impressed you did not get swayed by that book.”

“Yes. I have my own way. I have no intention of going along with others.”

Going her own path—truly, that was Mahiru. She suddenly seemed cool to me.

“I won’t use duct tape or make you smell socks. A little sister’s role is to act with her big brother’s best interests in mind!”

“You’re still the best little sister, Mahiru.”

“Big brother!”

Mahiru leaped toward me, her eyes sparkling.

It was the moment I truly felt grateful all over again that Mahiru was my little sister.

However, I did not know it at the time.

I never imagined I would suffer the greatest humiliation of my life by having my little sister put a diaper on me…

In the end, no matter the world, those who create are far more terrifying than those who merely imitate.

Fools and geniuses are separated by a single sheet of paper—no, little sisters and yanderes are separated by a single sheet of paper.
