Chapter 46: Date (6)
Chapter 46: Date (6)
It was evening by the time we left the karaoke room.
The sun had set, and the sky was already stained with the dark hues of twilight.
My sister and I stepped outside, our appearances somewhat disheveled.
Of course, I say disheveled, but we had tidied ourselves up to some extent. It made sense, considering what we’d actually done hadn't been enough to leave us looking truly a mess.
The part-timer didn't even spare us a glance as we left, so I figured we were fine on that front.
The problem was the emotional side of things.
My younger sister and I locked eyes.
Normally, such a glance would lead to casual conversation, but we both remained silent, warily gauging each other's reactions.
Yuri stayed quiet to see how I would act, and I stayed quiet because I was busy processing her behavior, the feelings she harbored for me, and—furthermore—the things I had done to her.
It was an awkward silence. Even though we were well away from the karaoke room, the stillness persisted, with only the sound of the wind filling the gap between us.
The usual jokes and small talk failed to surface. We just stood there blankly at the crosswalk, waiting for the light to change.
It was understandable. Everything I had just experienced made it impossible for such words to come out.
I stole a glance at Yuri. My own sister was standing there with an expression that looked strangely relieved.
Yuri met my gaze but didn't bother to speak. Instead, she quietly placed her index finger against her lips.
‘Shh.’
Watching her lips curve into that smile, I felt my heart still racing wildly.
I felt like I was going crazy. To feel my heart flutter and pound just by looking at my sister’s lips... I knew I had been broken for a long time, but now I realized there was truly no turning back.
Not that there ever really was. I looked ahead, feeling a sigh threatening to escape. The light was still red.
The things I’d experienced, the things I’d done with my sister, came back to me vividly.
In that karaoke room, we had kissed well over ten times.
With the blood rushing there, a certain part of my body had become prominently erect, and that part of me had pressed against her without reservation.
Pressing firmly, as we slickly exchanged body fluids.
We had been in contact for so long that parts of her stockings were even stained with those fluids.
There was no room for doubt. If she had asked, the best I could have done was tell the truth.
Entangling myself with Eldest Noona and Kang Yu-min was already a path destined for catastrophe, and now Yuri had been added to the mix.
And it wasn't just a simple addition. The fact that this wasn't a path chosen simply by losing to lust and desire weighed heavily on my chest.
‘Oppa, I love you.’
My sister’s confession—whispering that she was a bad girl—still drifted around my ears like a phantom.
Even amidst our repeated kisses, she had whispered her love for me over and over again.
It was incomprehensible.
What on earth had I done to make her fall for me?
On the other hand, it also provided the answer to many questions.
I used to wonder why a girl as kind and pretty as Yuri had remained single all this time, never having been in a relationship.
The reason was now crystal clear. Clear enough that even a clueless bastard like me could see it.
My sister loved me.
She had loved me for so long that I couldn't even guess when it started.
Though I had no idea why.
I couldn't dismiss her feelings as a passing whim or a misunderstanding. If they were, Yuri would have been the first to realize it.
Rather, I was certain that the feelings my sister held for me were a vivid, genuine sincerity. A sigh escaped me involuntarily.
How did it come to this?
My thoughts spiraled. Was it because I was too kind to her? Or was it some action I don't even remember?
No matter how much I retraced my steps, nothing came to mind. I found myself still standing there even after the light had changed.
“Oppa.”
I didn't snap out of it until I felt a sudden tug on my sleeve.
Only then did I regain my senses, look at the signal, and start walking.
“What are you thinking about so hard?”
Yuri spoke to me as if nothing had happened, and I hesitated for a moment at her words.
Was she trying to act like it never happened?
The hope that she was made me open my mouth first.
“Just... nothing.”
“Was kissing me that good?”
But I was wrong. My body gave a slight tremor. I felt the warmth of her hand as she suddenly took mine, and I stammered.
“I liked it. Kissing you a lot, a whole, whole lot.”
Yuri looked back at me with a smirk. She even matched her pace to mine, walking beside me and naturally linking her arm with mine.
With her arm linked and our fingers intertwined, she leaned her head on my shoulder, looking incredibly happy.
“Your lips were warm and felt so good, Oppa. You were so turned on because of me, and that made me excited too.”
“I…”
“When you grabbed my wrists so tight I couldn't pull away, my heart fluttered. It’s still pounding.”
Yuri lifted her wrist to show me. When I swallowed hard, she giggled.
“I hope you do it again later~”
She was right. Succumbing to the excitement and the sense of depravity filling my head, I had gripped her wrists tight so she couldn't escape, repeatedly pressing my lips to hers and entangling our tongues.
The moans and ragged breaths that filled my mouth had been nothing short of sweet. Even now, I found my eyes drifting toward her lips instinctively.
It was almost beyond desire; it was like a basic need. Like feeling hungry when your stomach is empty or feeling drowsy when you're tired.
Because it had built up, I wanted to vent it on my sister. Just as I was realizing that my brain had completely rotted away, she asked:
“So, Oppa.”
“…Yeah.”
“Can you feel the 10x Stamina?”
I didn't know. It wasn't like I’d done anything that required that much energy, so I didn't feel particularly drained.
We had only shared some intense deep kissing in a karaoke room; it would be weirder if that actually exhausted me.
Just as I was thinking it would be hard to tell unless I did something more serious, Yuri spoke.
“I wonder how far the '10x' goes?”
“…Well, I don't know. It wasn't written in detail.”
Even if I pulled out my smartphone and turned on the screen now, no specific explanation would appear.
Exactly what level "10x" meant, or if it was based on my current physical condition.
And exactly what the scope of "stamina" included.
It was clear I’d have to find out for myself, but one thing was certain.
This game was precisely giving me what I needed, and it wanted me to engage in intense incest.
In that sense, I could narrow down a few areas where this stamina would definitely apply.
One example would be my virility.
I was just about to suppress that thought, as it wasn't something I could tell my sister.
“Are you going to find out with the Unnies?”
My body flinched. It was a good thing we had already finished crossing the street, or it could have been dangerous.
I felt a cold sweat breaking out. I felt a certain sticky presence emanating from her through her tight grip on my arm.
A desperate excuse formed in my mind and tumbled out of my mouth.
“I... I should probably exercise with Kang Yu-min. Or…”
“Hmm? No, not that.”
“Th-en?”
“Didn't you get it so you could use it with the Unnies?”
Despite her avoiding explicit language, the meaning was crystal clear. My pupils trembling, I slowly turned to look at my sister.
My heart hammered against my ribs. My breathing grew heavy, and I could feel my face flushing.
Despite that, my brain kept recalling everything I had experienced.
Kang Yu-min, panting as she collapsed on top of me.
Eldest Noona, tangled in the same bed as me, dripping with sweat and letting out lewd moans.
And Yuri’s image seemed to overlap with them. I had to squeeze my eyes shut.
“Oppa, it’s dangerous to walk with your eyes closed.”
“…Right, yeah.”
As long as I was walking with this smirking girl, it probably wasn't actually dangerous, but I opened my eyes and thought.
There was no need to ask. Yuri vaguely knew what had been going on.
But how?
I thought I had hidden it well.
I couldn't say the frequency was low, but with the help of Eldest Noona or Kang Yu-min, I was usually quick and thorough about cleaning up.
It wasn't like a typical affair where you might get caught; there was no need to be excessively meticulous.
We didn't use condoms, so there were no used ones to be found. There was no risk of being caught just because we showered together—it was common for the whole family's hair to be in the drain.
The rooms were sufficiently soundproofed, and since we were the only ones using the entire building, the spaces were separated.
That meant there was no chance of being caught in the act. Even though Yuri often came up to the third floor where my room and Kang Yu-min’s were.
It wasn't like we wouldn't notice her entering the passcode and coming in.
That’s why I had been extra careful, and I thought I hadn't given her any reason to be suspicious.
How on earth?
My eyes drifted toward Yuri, and she tilted her head curiously while clinging to my side.
It was as if she was waiting for me to ask her directly.
But I couldn't bring myself to ask her.
How did you know? Why are you asking that?
I couldn't ask. I didn't even know why.
“Coward.”
Ignoring her sweet, seductive whisper, I headed home with her.
Yuri walked silently beside me, looking pleased as she even hummed a little tune.
I knew why she was in a good mood, but I wondered if this was really okay.
As I was worrying, I was snapped back to reality by Yuri’s cheerful voice.
“Oppa, my birthday is coming up soon.”
“…Yeah, it is.”
“I want to go on a date with just the two of us that day, too.”
I gulped. My Adam's apple bobbed, and Yuri’s narrowed eyes turned toward me.
“Is that a no?”
She wasn't acting cute like usual, nor was she looking up at me with pitiful eyes.
Instead, she looked at me with a sultry, heavy-lidded gaze. As our eyes met, a shiver ran down my spine.
“There’s a gift I want to receive.”
“What kind of... gift?”
“It’s a secret.”
I couldn't even tell her to let me know in advance so I could prepare it.
Because I had a vague feeling that the gift Yuri wanted was something I could give her right then and there.
“Do you hate the idea?”
Tilting her head, she pulled away slightly to face me. She leaned forward a bit, her side-swept hair swaying with her tilted head.
I realized once again that I was already completely broken, and I could no longer refuse her.
“No, I don't hate it.”
Only then did Yuri give a bright smile. Her sultry eyes were silently reflecting my image.
“I’ll be looking forward to it.”
Yuri went into the house first, and I stood there for a long time, savoring the sense of depravity she had left behind.
