Chapter 158: Side Story - Bunker (16) ♥
Does the hymen actually exist? It was something I hadn't known much about until now, but it existed as something that was a membrane, yet not quite a membrane.
How should I put it? Calling it a "membrane" felt like a bit of an overstatement.
It was more like a string draped across the opening. It was pure white, but so drenched in arousal fluid that it wouldn't have been strange for it to snap at any moment.
I tore through it, piercing her with my cock as I pushed inside.
"Ngh, ah, h-hiii...!"
Kang Yu-min’s grating voice—the one that usually annoyed the hell out of me—melted into a sweet, honeyed tone, transforming into a moan that was a pleasure to hear.
"Ngh, ah, Yu-jin... ah..."
Even the way she called my name was sweet. I felt an intense surge of pleasure rush up the back of my neck.
Her pussy was incredibly tight. It wasn't like I had experience with sex, but even a novice like me could tell that Kang Yu-min’s pussy was delivering an overwhelming amount of pleasure.
It felt like I would ejaculate the moment I let my guard down even an inch.
Since it was my first time, I couldn't let that happen. Thinking it would be a waste to finish so soon, I desperately grit my teeth.
"Hey, Kang Yu-min... your legs..."
"Ngh, mmm, nngh...?"
"Spread your legs wider..."
"Haa, ngh, yes, do it..."
Normally, I would have frowned at her coquettish tone, but strangely, I couldn't.
Instead, I couldn't take my eyes or ears off her melting expression and that voice.
"My legs... hold my legs..."
"So demanding."
"You... ah, it feels so good..."
I couldn't ignore her in this state. I grabbed Kang Yu-min’s thighs and pulled them apart, and she endured the weight of my cock while her ankles trembled uncontrollably.
My cock buried itself deep inside, and I felt something firm being crushed by my glans. As I let out a ragged breath and began to drool unconsciously, Kang Yu-min looked up at me with a dazed expression.
"Ah, seriously... I feel like I'm going to cum already..."
Our eyes met. At my honest slip of the tongue, Kang Yu-min gave a faint, silly smile.
"Does it... feel good?"
"Incredibly..."
"Me too... ngh, haa."
As my cock throbbed inside her, Kang Yu-min moaned and opened her mouth, sticking out her tongue.
She looked so lewd and disheveled, swallowing the saliva that dripped from my mouth. It was a sight that would provoke desire in any man. I grit my teeth and slowly pulled my hips back.
At that, Kang Yu-min threw her head back and let out a moan. The sound, which almost sounded like crying, mingled with the wet, squelching sound of her leaking juices.
Every bit of it was unbearably stimulating.
The sense of conquest from breaking my own sister’s virginity made me pause for a moment, despite the pleasure coursing through my waist.
The tightness was so intense that I felt like I would lose control and thrust wildly if I didn't hold back.
A pussy that was filled to the brim by my cock, gripping it in its exact shape.
It was hard to believe this was my sister’s pussy.
Kang Yu-min’s pussy felt amazing. Her vaginal opening wrapped around the base of my cock as if it never wanted to let go, dripping with fluid.
Through that sensation, I could tell our sexual compatibility was perfect.
Even though we were siblings. Even though we were in a relationship where we shouldn't be having sex, let alone discovering how well we fit together.
Our chemistry was so good that just being buried inside each other felt like it would bring us to climax. It was unbelievable.
Even though I was wearing a condom and could have just let go, my pride and the desire to keep thrusting into this incredible pussy made me fight to hold back my ejaculation.
"Kang Yu-min..."
Panting, her tongue out as she breathed heavily, Kang Yu-min looked at me. Seeing her tongue, I reflexively lowered my head and met it with mine.
"Mmph...?!"
The sound she made in her confusion was cute. Even though it wasn't an emotion I should be feeling for Kang Yu-min, I felt it with both my heart and my cock. I kissed her, feeling her give up her tongue without resistance.
It was my first kiss.
Even my first kiss was with a family member—my own sister.
Giving my first sex and my first kiss to my sister, I felt an intense sense of depravity.
It was something that would never have been permitted if the world were still sane. And yet, even if the world were normal, it was something so addictive that I wouldn't have been able to stop once I had a taste.
And right now, this was our own private deviation that no one could judge.
As I sucked in a breath, Kang Yu-min wrapped her trembling hands around the back of my neck.
We kissed with our eyes wide and dazed. As our lips rubbed together and our tongues intertwined, her pussy twitched.
Her internal movements were sharp, as if her uterus were aching, and her vaginal opening continued to squeeze me so hard it felt like it would snap my cock off.
Feeling myself being molded into a shape and size that felt like it was made specifically for me, I slowly began to move my hips.
Tasting Kang Yu-min’s moans through her mouth, drinking in her saliva that still carried a faint hint of cola.
We rolled around on the bed, our bodies overlapping and drenched in sweat, making the new bedding look like a waste.
If I knew it would feel this good, I should have done it sooner.
No, no matter what, she's family. This isn't right.
As my eyes trembled with these two conflicting thoughts, Kang Yu-min met my gaze, closed her eyes tightly, and pressed her lips against mine.
Connected above and below, I felt her plump breasts pressed against my chest.
I felt her slender, yet toned body convulsing beneath me, acting spoiled in her pleasure.
I gradually increased the speed of my hips.
My movements were clumsy. Kang Yu-min was also awkward at receiving me; her thighs, which I was holding, were trembling so much she couldn't even support herself.
But I was too caught up in the pleasure to care, busy huffing as I thrust my cock deep into her pussy over and over again.
Until our fluids overflowed and mixed, and the lubricant on the condom was stained with her juices, giving off a lewd scent.
I had to stop every time I felt like I was going to ejaculate, and with each pause, I felt the pleasure swelling until I reached a point where I could no longer endure it.
Even when I tried to pull my lips away, Kang Yu-min clung to me.
Even when I managed to pull back, she would press her lips against mine again and again.
It was only after a long while that I managed to speak.
"I... I'm about to... cum."
Even as I spoke, Kang Yu-min hurriedly pressed her lips to mine, licking my saliva with the tip of her tongue. As her tongue slid over my lips, a shiver of pleasure ran down my spine.
"I said I'm going to cum, Kang Yu-min."
"Then do it."
"But..."
"You have a condom on."
My body twitched. It would certainly be fine since I had a condom, but to have a creampie against her cervix at the end of incestuous sex...
It felt like I was doing something truly unforgivable. Especially since it was incest.
We had agreed to call it "masturbation," but that didn't change the reality of what was happening.
I hesitated, but Kang Yu-min did not.
With a face that had completely melted—a face that could only be described as a female in heat—she met my eyes and pressed her forehead against mine.
"Fill me up... deep inside."
At those carefully chosen words, I could no longer hold back. As I grit my teeth, Kang Yu-min gave a silly grin, closed her eyes again, and kissed me.
I moved my body. Sliding my hands from her thighs to her ankles, I lifted her hips high and slammed back down.
With a sound somewhere between a thud and a splash, our fluids mixed, creating a lewd watery sound and the sound of flesh hitting flesh. Kang Yu-min filled my mouth with her moans as her waist trembled.
As her chest heaved in a desperate search for air, I gradually quickened my pace.
By instinct, I corrected my clumsy thrusting.
Becoming more like a beast—faster and rougher.
Naturally, our lips parted. Kang Yu-min stuck out her tongue as if desperate for a kiss, then threw her head back.
Her long, drawn-out cries were like those of an animal. Screams of pleasure she couldn't contain because it felt too good. I didn't stop, moving even faster toward my climax.
Her inner flesh, already a pale pink, became flushed and red. Her overflowing juices soaked the sheets and left a strange sensation on my thighs.
"In... ngh, inside...!"
Responding to the words Kang Yu-min barely managed to squeeze out, I drove my hips down hard, hammering against her cervix.
And then.
"I'm cumming...!"
I began to spray a volume of semen toward her uterus that would have surely resulted in pregnancy if not for the condom.
Though blocked by the useless wall of the condom, the sheer will, volume, and intensity of the ejaculation made it feel as if it would pierce right through.
It was an embarrassingly large amount of semen for something produced through incest.
I had already come a lot in her mouth earlier, and she had drained me for "dessert" this morning, too.
Feeling as if every last drop of my soul was being sucked out, I curled my toes as I ejaculated into my lewd sister’s pussy.
When I finally finished, I wasn't met with post-nut clarity, but rather a deep sense of fulfillment.
At the end of an ejaculation that felt like a total liberation, I slowly lowered Kang Yu-min’s ankles onto the bed and pulled my cock out.
"...Ah."
As I pulled out, the full condom sagged and fell with a soft thud. It landed, spilling semen as it settled. Kang Yu-min, her body drenched in sweat, dazed, traced the spilled semen with her fingertip.
"...You pervert."
It wasn't exactly something she should be saying while licking her younger brother's semen off her stomach.
Unable to even offer a rebuttal, I silently kissed her.
A lewd, lover-like kiss that no siblings, no matter how close, should ever share.
"It's been a long time since I felt this good."
Even though everything was over, we didn't get up; we just lay there on the bed.
We didn't pull up the covers. There was semen and arousal fluid everywhere, so we couldn't exactly do that.
I just lay there quietly, staring blankly as Kang Yu-min snuggled into the crook of my arm.
She was clinging to me like a lover, not a sister.
I kept the thought to myself, though, because I didn't mind lounging like this right after sex either.
"I think this was a first for me."
"Really?"
"Male masturbation isn't usually that pleasurable."
It was the truth. Unless one was doing something very specific, male masturbation was generally simple and the pleasure was relatively thin.
The pleasure was concentrated in the moment of ejaculation, so in terms of the pure quality of the act, women had the upper hand.
I was still drained from the intense pleasure I had experienced for the first time.
"You must have liked it that much? Your sister’s pussy."
"Yeah. We're compatible."
Perhaps that was why Kang Yu-min also seemed quite satisfied.
Even at the words I said to make her embarrassed.
"You're right. We really are compatible. I've never used a dildo or anything, but I don't think a dildo would feel this good."
She actually answered quite seriously.
Doesn't this girl have any shame? I wondered.
But then again, we had already had sex and I'd come inside her (even with a condom), so maybe there was nothing left to be ashamed of.
So, I answered nonchalantly.
"Is that so?"
"Yeah. It was warm, full, just right... it hit all my sensitive spots at once... I thought I was going to faint at first. It felt too good."
The compliments that followed were only things that made me feel embarrassed. I subtly turned my head away, and Kang Yu-min smirked at me.
I gave a grumpy reply.
"Stop exaggerating."
"I'm not exaggerating. Anyway, from now on, this is mine. Got it?"
Kang Yu-min laughed as if she found my reaction cute, grabbing my cock and displaying her possessiveness.
And as the only "sane" person in this bunker, I couldn't let myself lose. Not to be outdone, I reached out and squeezed her pussy. Kang Yu-min flushed and flinched at my touch, but she stayed still.
"Fine, fine. Then your pussy is mine too, okay?"
"...Of course. No more masturbating with your hand from now on. I'll only allow you to masturbate using your sister’s pussy."
Kang Yu-min smiled happily at the possessiveness I showed. Her face, which would usually have annoyed me, looked beautiful, so I grumbled pointlessly.
"What do you mean, 'allow'..."
Kang Yu-min gave a silly giggle at my words. I looked at her and then kissed her.
It was a kiss far too intimate and full of love to be between two people who were just using each other as masturbation tools.
