Chapter 31: Younger Sibling (5)
Chapter 31: Younger Sibling (5)
Regardless of how I felt, I was ultimately inside a game. Every emotional shift I experienced here wasn't real.
I managed to regain my composure by repeating that to myself. It was a peace that wouldn't last long, however.
The reason for that was actually quite simple to discern.
"Hmm? You don't like it?"
The presence of my younger sister, clinging to my side, was making sure of that.
In the past, I wouldn't have reacted this strongly. But after playing this game for nearly two months—and spending about a month of that time with Kang Yu-min in a state no different from being lovers—things had changed.
Right now, I was perceiving my own flesh and blood, the younger sister I had spent my entire life with, as a woman.
My brain was definitely broken. A sigh threatened to escape, but I couldn't let it show. If she found out her own brother saw her as a woman, she’d only be disgusted.
And the thought of Yuri distancing herself from me because I was "creepy"... just imagining it made me dizzy. I struggled to maintain my composure while trying to act as natural as possible.
"No, it’s pretty. Really... but isn't it a bit indecent?"
"Is it? Does it look sexy to you, Oppa?"
Yuri chuckled, fluttering the coat she had draped over herself. I swallowed hard at the sight of the coat, which left the interior clearly visible. She didn't hear that, did she?
"Honestly, yeah. Just look at how much skin is showing."
Perhaps my nonchalant response was unexpected. Yuri twitched an eyebrow and let out a soft "Hmph."
Was she dissatisfied? Had she hoped I would be more flustered?
But I wasn't the same person I used to be. The current me was...
Wait, no, isn't the current me actually worse?
Yuri didn't let me go when she saw me momentarily panic.
"Chee, I wanted to see you get flustered, Oppa."
Grumbling, Yuri flopped down with a splash, resting her head on my lap.
The spa was divided into two levels, so to speak.
There was the area where Yuri and I were currently sitting, designed for enjoying the bath while seated.
And then there was the section with water deep enough to submerge the entire body, almost like a swimming pool.
In that sense, the part where I sat was the shallow side.
When Yuri used my lap as a pillow, it was shallow enough that even if I panicked, she wouldn't fall into the water.
"I mean... what's the point of seeing me flustered?"
"Hmm? You don't know?"
"I don't."
Thinking back, I feel like I heard similar things quite often during our school days.
What was so great about me being flustered? It was incomprehensible to me, but Yuri answered my question simply.
"You're cute when you're flustered, Oppa."
"Calling your brother cute. Is it really okay to call a grown man older than you 'cute'?"
"But it's true. All my friends say you're cute, too."
"...Why, exactly?"
I could not understand high school girls. What was I to them that they’d say such things?
"There's a reason for everything."
Yuri didn't give me the answer. Instead, as if telling me to figure it out myself, she stretched her arm out while still lying on my lap and tapped my cheek.
"Meow, meow."
"...You're a grown girl, what are you doing?"
"Am I not cute? This is your cute little sister acting adorable, you know?"
"...You are cute."
Aside from her scandalous attire, Yuri was Yuri, same as always.
A girl who knew exactly how much she was loved and knew how to use it to her advantage.
She was the type to act cute, throw tantrums, and affectionately cling to me, our eldest sister, and even Kang Yu-min when necessary.
One might expect her to feel some shame, but even her displays of aegyo felt natural. Perhaps it was because she was the youngest.
I reached out to stroke Yuri's head but stopped my hand.
We were in a spa. Instead of the usual pleasant feeling of stroking her hair, it would just be wet and damp.
"What? Aren't you going to pet me?"
Yuri looked up with disappointed eyes. After a moment's hesitation, I lowered my hand and touched her cheek instead.
Even though it was wet, the cheek I caressed left a vividly pleasant sensation.
As expected of a high school girl's skin, I suppose. The supple, firm texture felt incredibly good.
"Mmm, why are you touching me so much...?"
"As expected of a high school girl's cheek."
"What are you even saying... You're really weird sometimes, Oppa..."
"Squish, squish."
Yuri beamed at me, and I continued to touch her cheek. In that moment, the sense of depravity and the impulses that had filled my head began to slowly fade away.

My heart rate was entering the safety zone. That was because I was starting to see Yuri as my younger sister again, not as a woman.
Yes, this is how it should be. I stroked Yuri's cheek, thinking that perhaps she was being considerate of me.
"...Your heart rate went down, Oppa?"
I snapped out of it at the sound of her chillingly calm voice.
A shiver ran down my spine. I blinked, my eyes wide with confusion.
"Uh, how did you..."
"It showed me."
Wait, it shows her that? While flustered, I recalled the true purpose of this game.
It was a game that desperately wanted me to commit incest with my family. So, it wasn't strange for it to show such things to my sister.
Wait, was it?
What would change by showing her that? I wondered, but...
"Am I really cute? Why do you get so calm when you're stuck this close to a cute girl?"
Yuri sat up with a pout. Her water-soaked body glistened under the light.
I saw the alluring lines of her body, the kind that made my slow-beating heart want to race wildly. I struggled to keep myself under control.
"...I guess the clothes are pretty?"
Right now, I had to remember the fact that my heart rate was visible to my sister.
"No, it's just... because you're my sister? It's not strange to feel comfortable around you."
If there was one saving grace, it was that Yuri possessed some level of common sense.
Actually, Yuri had a bit of a "princess complex."
Perhaps it was because she knew she was pretty, was used to being adored, and knew that everyone liked her.
It felt like she had a compulsion to be seen that way. It was the same now.
Even though we were family, she had an obsession with looking pretty to me. In that sense, even if she couldn't refute my words, she seemed displeased.
At least the fact that she couldn't refute them was a relief.
"But do your clothes make your heart flutter?"
Yuri grinned. I laughed awkwardly, wondering how I should respond.
I couldn't shake the thought that no matter what I said, I would sound like some crazy person committing incest.
Which was technically true, and I actually had committed it, but...
I didn't answer and tried to brush it off.
Unfortunately, it seemed Yuri found a way to use even that silence.
"Then, does it flutter more if I do this?"
Yuri took my hand. I could have pulled away if I used force, but as I hesitated, not wanting to be rough with my sister, my hand was drawn closer to her chest.
Wait, this is... hold on. This is dangerous.
Just as I thought about pulling my hand away, it stopped over her coat.
Giggling, my sister peered into my face.
"Oppa, your face is turning red. What were you thinking?"
"Wait, you... family members shouldn't do this..."
"Hmm? I'm just letting you touch my clothes. Are you thinking something weird, Oppa? About Yuri?"
I reflexively swallowed. I could feel my heart pounding wildly. Even as I felt my heart rate climbing steeply, her interlaced fingers led mine past the transparent coat.
A vivid water trail was left behind. Yuri teased me with a mischievous smile.
Strangely, it wasn't an unpleasant mockery. Was it because the one doing it was Yuri?
Right, it was just me having weird thoughts; Yuri probably didn't have any such intentions.
At least, that was what I tried to tell myself.
"How is it?"
"Even if you ask me how it is..."
"The clothes, I mean. Are they pretty?"
"Uh, yeah, they're pretty. Pretty, but..."
"If they're pretty, do you want to look closer?"
My sister grinned. I couldn't understand what she was hoping to achieve by doing this.
In truth, it had always been like this. Even though I thought I was the closest to my sister, there were many times when I couldn't fathom what was going on in her head.
She was cute, pretty, polite, and full of aegyo.
But on the other hand, it was difficult to know what thoughts she harbored deep inside. It was the same now.
I didn't know what she wanted from me.
"Is... is your allowance not enough? Is that why...?"
"...Huh?"
Her face turned toward me, grinning. She was close. Before I knew it, my sister was sitting on my lap.
For a moment, I felt the blood rush to my lower body. The rough acts I had engaged in with Kang Yu-min just yesterday flashed through my mind.
I found myself swallowing hard. Oh, come to think of it.
Did I clear away the condoms? I thought I put them in the trash.
The faint memory didn't last long. Yuri's hand led mine and placed it back on her cheek.
Her skin was elastic and supple, as if it were sucking my fingers in.
My hand slid over that skin. As Yuri pressed down with her thumb, my own thumb bent, and the folded digit pressed against her lips.
I couldn't help but be startled. A subtle excitement that raced from my fingers through my entire body was concentrating heavily in my lower half.
I had to pull my hips away. So she wouldn't find out, so I wouldn't cross the final line.
With that desperate thought, I tried to pull back, but Yuri pressed closer again. My body froze, and as I felt Yuri's stomach touching me, I went completely rigid.
"Oppa, you're cute."
Yuri pressed my thumb firmly against her lips and gave it a light kiss.
A searing heat raced through my finger. Those lips.
They were supple lips that reflexively made me want to kiss them or imagine what lay beyond.
As I let out a ragged breath despite myself, Yuri smiled brightly and stepped back slightly.
"I think that's enough... How do I look?"
Yuri spread her arms and spun around as if showing off.
I felt my gaze drawn to her instinctively, unable to look away.
The elegant curves, the fullness of her thighs leading into long legs.
Her buttocks, slightly visible even from the front. The prominent line of her hips and breasts that were so full they seemed to overflow a single hand.
Taking it all in, I parted my lips.
"Am I pretty?"
"...Yeah, you're pretty."
In the end, I had no choice but to admit it.
Only then did Yuri give a refreshed smile and stride out of the bath.
"I'll wash up and head out first! Take your time!"
The mischievous curve of her eyes was seductive. I squeezed my eyes shut, feeling a simultaneous sense of self-loathing and arousal at the fact that I had thought of my sister that way.

Despite everything, the clearly visible quest window seemed to mock me.
Amidst my lamentations, I prayed that there would be no more quests to follow.
Fortunately, the game seemed to have no intention of teasing me further.
From that point until we turned the game off, no more quests appeared.
