Chapter 45: Date (5)
Chapter 45: Date (5)
It wasn't my first kiss.
It wasn't as if I’d never kissed anyone in my life, and lately, the frequency had been increasing quite a bit.
So, normally, it shouldn't have been a big deal. Or rather, I should say I was desperately hoping it wouldn't be.
But I couldn't for a moment forget the fact that I was kissing my younger sister.
After all, Yu-ri was right there in front of me.
I could feel her body heat. The warmth radiating through our touching skin was scorching.
I felt her breath against my overlapping lips, carrying that same feverish heat.
I felt her hand, which was gripping my forearm and sleeve tightly, trembling ever so slightly.
It wasn't a tremble born of fear that I might reject her. If anything, I could feel that she didn't care about that at all.
She was a sister who held herself back despite her clear desire to ravenously devour my lips, simply because she sensed my hesitation.
Yet, paradoxically, I was becoming aroused by her kiss.
Heat surged through my entire body, and blood rushed to my core. My breath hitched of its own accord, and I stiffened my body, trying to resist the violent desire swelling in a specific part of me.
Even so, Yu-ri didn't stop. She must have noticed the tension in me, yet she didn't hesitate. With our lips pressed together, she continued to brush hers against mine.
The sensation...
It was beyond anything I could have imagined.
Even setting aside the fact that I had never even tried to imagine such a thing, it was overwhelming.
It was a sweet kiss that shattered every "what if" and dragged out a desire I had harbored in my heart but never voiced—a desire I hadn't even known existed.
A giggle escaped her between our mingling lips.
That laugh sent a shiver racing down my spine.
Goosebumps broke out over my skin. It seeped into my brain more intensely than a breath whispered in my ear.
The hot sensation, broken up with every syllable. It felt as if each one was carving into my mind.
I couldn't help but shudder. But Yu-ri didn't stop, even at that.
Even though it was a kiss performed for a simple objective, she lingered as if she were reluctant to let go. As she continued, I found myself unable to move a muscle.
Only after what felt like an eternity did she pull her lips away.
I felt a faint trace of saliva. Just barely, beyond the warmth spread across my lips.
That soft texture—more than the heat itself, the fact that it was my sister's saliva made me freeze.
Though it was just one kiss, both of us were breathing heavily. In the silence of the karaoke room, we were in a state that siblings left alone in a private space should never be in.
"...Yu-ri. I..."
"Shh."
Yu-ri’s index finger pressed against my lips. I stopped talking, and as if by some law of inertia, I forgot everything I was about to say.
That we were family.
Asking what she meant by calling herself a bad girl.
Asking why she did this—all those reasonable, brotherly questions.
It felt as if they were all draining out of my brain. Yu-ri was panting, her eyes half-lidded as she looked at me.
I could see her flushed cheeks, her burning ears, and the rise and fall of her chest.
I was likely the same. My brain already compromised, I was feeling pleasure and excitement before any sense of depravity while kissing my sister.
I was even feeling my heart flutter just by looking at her face.
It was understandable, in a way. She was beautiful.
She was different from Kang Yu-min, who didn't bother with her appearance, or myself.
There was a fresh, vibrant charm to her face.
Clear eyes, soft skin—skin that was flushed even beneath the fine peach fuzz.
With light makeup that highlighted her charms while looking natural, the seductiveness dwelling in her cute features elevated both her loveliness and her allure.
It was a "gap moe" in the truest sense. And she was a clever girl who knew that fact well and used it to her advantage.
Yu-ri let out a low chuckle, removed her finger from my lips, and gently pulled the smartphone from my hand to look at it.
[Kiss your younger sister, Kang Yu-ri. 3/10]

"Hmm, even if we do it for a long time, it only counts as one. That’s a relief."
A relief? I didn't have the composure to ask what she meant.
Before I could even think to ask, she wrapped her arms around my neck.
Before I knew it, our eyes met, and the tips of our noses brushed. And in her eyes...
A powerful lust was swirling—one I never thought I would see in Yu-ri.
"Oppa."
"...Yeah?"
"I love you."
My heart dropped, yet it began to pound violently.
It felt as if my thumping heart was about to burst out of my chest.
The shock was so great it felt like my breath had stopped, and I had to just stand there and take it.
My memories clashed with the reality before my eyes.
Yu-ri, laughing innocently while holding my hand. A little child, a local kindergartner.
'Oppa, I love you!'
A clear laugh. That pure, stainless smile.
It was a smile I always wanted to protect. Even as time passed and she became an elementary schooler, that fact didn't change.
'I like Oppa the best.'
Yu-ri, grinning as she played with a game console on my lap. Her missing baby teeth blended with her bright smile.
She was a lovely younger sister. I thought she would stay that way forever.
'Huh? The person I like most? It’s Oppa, obviously.'
The sister who would answer nonchalantly and wink. A cute girl who knew her own charm and used it actively.
I would play along with her aegyo and act like a doting brother, and she would laugh and call me a dork.
But sometimes, she would wear an expression I couldn't quite read.
Time passed, and she reached high school. She became even more proactive with her affection.
'Oppa!'
She would hug my arm, claiming we’d met by chance outside.
'Oppa~'
She would naturally use my lap as a pillow while I sat on the sofa, acting cute.
'Oppa...'
The Yu-ri who spoke with tears in her eyes on the day I left for the military, as if the sky were falling.
Recalling the things I had forgotten for so long, I realized that high-school Yu-ri had hidden her feelings remarkably well.
I finally understood the meaning behind those unreadable expressions she’d made since middle school.
Only then did a sense of guilt fill the void. Yet, the heat within me did not fade.
My heart raced wildly as I looked at my sister, who wore a mischievous smile. My sister, who was about to become an adult, with her graduation ceremony just around the corner.
A sense of depravity bloomed. The sister I had ruined with my own hands was right in front of me.
She was a sister I hadn't even realized I was ruining. A sister who had been throwing her emotions at me constantly, without pause.
Yu-ri spoke not as a sister, but as a woman.
"I love you."
"Yu-ri..."
"I love you more than anyone in the world."
It sounded like a sweet confession, but in reality, it wasn't.
[Kiss your younger sister, Kang Yu-ri. 4/10]
[5/10]
Yu-ri’s breath tickled my skin, and a shower of kisses peppered my cheeks, my eyelids, and my nose.
I was out of breath. She kissed me repeatedly as if to seduce me, yet she pointedly avoided my lips.
Blood naturally rushed to my lower half. Sensing this, Yu-ri gave a small shudder and smiled brightly.
[6/10]
Cupping both my cheeks, Yu-ri kissed my chin. Her lips brushed over the rough stubble, moving along the contours of my face to graze my neck.
[7/10]
Mwah.
Our cheeks pressed together, and her lips touched my earlobe. It was hot. It felt like my ear was melting. My body flinched at the deliberate sound she made. As a heavy breath escaped my mouth, she held my cheeks and smiled faintly.
A glimmer of reason remained.
Was this okay?
Shouldn't I stop this?
But despite those thoughts, my body couldn't reject her, and Yu-ri didn't stop either.
Perhaps she was doing this because she knew I wouldn't push her away.
[8/10]
The sound of another kiss rang out. Her face, so close her lips almost brushed mine playfully, moved to kiss my cheek, and she let out a low giggle.
It was a pure smile, as if she truly couldn't help how much she enjoyed doing this to me. Seeing that smile, I felt my heart beat even more frantically.
"Oppa, does it feel good?"
"...I..."
"I like it. Can I do more? Hmm?"
Acting cute, she grabbed my forearm and brought her lips close, as if teasing me. Feeling a throbbing sensation in my temples, I squeezed my eyes shut as I watched her lips slowly approach.
It was coming. A shock that would surely demolish the last of my reason.
But what fell upon me was...
"Mwah."
The sound she made with her mouth, followed by a light kiss.
A kiss that landed on my lips and then pulled away. Amidst the emotional shock that felt like it was shaking my entire being, I exhaled sharply without realizing it.
When I opened my eyes, she was close.
With her arms around my neck, perched on top of me, she was looking at me with eyes saturated with deep affection.
It was a look one should never show a family member. Eyes that had melted as if she were deeply in love—eyes that were thick, wet, and dripping with honeyed desire.
It felt as if the very last shred of my reason was evaporating.
"Nine times."
I was reflected in her eyes. I was panting, wearing an expression that was not at all what a brother should look like after being kissed by his sister.
I looked like a man who had been kissed by a woman.
With an expression just as melted as hers, I tried to catch my breath.
"Ten."
Her lips approached, brushing, almost touching. As they grazed mine, a beep-beep-beep sound echoed.
In a sensation that felt like the faint heat within me was spreading through my entire body, I froze, locked in her gaze.
Yu-ri was still clinging to my neck, grinning.
Silence fell. In the space filled only by our frantic breathing...
I couldn't resist any longer.
My body moved on its own.
Our lips overlapped. I pressed my lips against her warm ones, wrapped my arm around her trembling waist, and tilted my head to deepen the kiss.
Her lips parted, and I pushed my tongue into the opening.
I reached out. My tongue tangled with hers—a greeting that was both strangely familiar and infinitely awkward.
Her tongue tasted like a sweet drink. I pulled her tongue deep into mine, holding her firmly so she couldn't escape as she let out small moans.
I swept over the root of her tongue, traced her teeth, and as I felt her labored breath being transmitted through my mouth, our tongues entwined.
Before I knew it, I was lying on the karaoke sofa with her.
A thread of saliva connecting her mouth to mine glistened in the light from the karaoke TV.
As I looked down in a daze at her profile illuminated by the dim TV light, she smiled.
With her clothes and hair disheveled, breathing heavily, the way her eyes curved into a thin, seductive smile was utterly captivating.
I pressed my lips against Yu-ri’s once again.
