The Thread That Snaps
"And most of all, I want to make my devoted fan happy — Dohyun oppa. So, starting right now, I'm going to offer my virginity to him."
On the screen, Silbi's voice gave way to the Silbi standing right in front of me, and as she lifted her skirt, a woman's sex was laid bare before my eyes without a shred of concealment.
A mound kept smooth and hairless, and beneath it, the parted slit.
The most hidden, most precious part of a woman's body.
And… the hole that could bear a child.
If I poured semen into it, a life would without question take root inside Silbi. The moment I pictured that weight, a brake slammed down on the impulse to bury myself inside her that very second.
"Don't worry, oppa. If you want, I won't have a child yet. I told you, didn't I? Controlling the human body's reactions is no trouble at all for me."
Having read the worry written across my face, Silbi soothed it away in a gentle voice.
"So don't think about any of that. Just think about becoming happy, oppa. Anything small, anything annoying, anything you'd have to take responsibility for — I'll handle all of it. All you have to do is use my body and feel pleasure."
Silbi smiled brightly and stretched both arms out toward me, as if asking to be held.
The seductive whisper — you don't have to take responsibility — clung sweetly to the rim of my ear.
"Or is it that you don't want your first time to be with this human woman's body? In that case…"
Her fingers spread the lips open, showing me the pink flesh within.
"…how am I, oppa? The virgin pussy of your own little sister, Yoon Ji-a? The body of the girl who spent her whole life denying you, who made you a thing to be compared against — Ji-a's flesh?"
Back in Ji-a's form, the demon spread the hole invitingly with her fingers, baring the pink flesh inside.
The moment I saw the most intimate part of the sister I had resented and, in some corner of myself, longed for — that tangle of love and hate — my pupils began to tremble.
Something rose up in me, impossible to name as arousal or rage or both at once, and my blood came to a boil.
I wanted to snap the lily blooming so proudly and shamelessly in that beautiful field of flowers.
I wanted to make my little sister… to make Yoon Ji-a cling to my feet, wailing, begging me for mercy.
"Haaah…"
The heat that burst from my lips carried excitement and a tremor in equal measure.
Watching me, the demon let out a delighted laugh.
"Ravage her. Tear her apart. Let everything you swallowed down explode. Bring the thing called Yoon Ji-a to her knees before you. Crush the one who looked down on you from so far above. Wield violence. Rape her. Defile her. Fill her outside and inside until every inch of her is yours. Make her remember you and you alone. Stuff this hole to overflowing with your cum. Just like you always wanted — paint over Ji-a's existence, all that flawlessness and cleanliness and purity, with yourself. Forever. So all she ever remembers is you."
Kikik.
A low chuckle spilled out of her.
I looked at the demon, beaming as if nothing in the world had ever been so funny, and spoke.
"Stop it… you. Didn't you say you didn't want to watch me suffer?"
"That's right. I don't want to see you suffer. That must never happen. But…"
At my trembling question the demon made a sullen face for an instant — then looked back at me and lifted a smile that seemed genuinely pleased.
"How am I supposed to read that face as suffering when you're grinning like that? You're happier right now than you have ever been. And I want to make that happiness come true."
At the demon's words I dragged both hands down my face.
Only then did I realize I was smiling — my features twisted into something unrecognizable.
"If you truly want me to stop, I'll stop. So let me ask you again, oppa. Ji-a's body… are you really okay not violating it like this? Are you… really okay?"
The demon asked carefully, Ji-a's face tilted up toward me, her eyes glistening with tears.
Trickle…
In stark contrast to the cautious gaze fixed on me, arousal was already streaming down from the hole between her legs.
Body and mind were both desperate to detonate the years of feeling I had piled up, ready to ignite at a touch — and yet one thing still snagged in my chest, keeping me from moving my fevered body.
The demon stared hard into my conflicted eyes… then her expression shifted to the bashful face of an innocent maiden.
"The truth is… oppa, I like you."
"…What?"
"Please, oppa…"
Grab.
Startled by words I never expected, I felt Ji-a's hands close around my wrists, and she spoke in a voice worn thin with sorrow.
"I don't want to give my first time to any other man… I want to give it to you, oppa. My first. My first everything. I want to remember my first time as you. So please… I'm begging you like this."
She pulled, and I was drawn into the cradle of her hips. Ji-a wrapped both arms around me and pressed her lips to my ear, whispering slowly, quietly.
"Rape me."
A decadent whisper.
The body heat wrapped around me — human warmth, proof that this was real, that I was fully alive inside this moment.
Ji-a's long black hair spilled down and teased across my skin; her fragrance washed over me again, sweet and pleasant. The scent of a woman.
Drip.
All of it fused into one, and in my head I heard a single taut thread go twang — stretched to its limit, fraying, and then snapping.
Thud.
I threw my little sister down onto the floor.
Her eyes went wide at the suddenness of it — and then a faint smile bloomed on her face, and she softly stroked the cheek of the man looming over her, his gaze burning with excitement.
"How handsome. How lovely. My love… my very own oppa."
Her cheeks flushed, a smile of pure rapture on her face.
If my little sister had still been alive… would she have ever made that face for me?
Did Ji-a… did she truly love me, once?
Softly.
I felt her fingers close around me as I rose up hard from below.
A hand considerate of a man doing this for the first time — it guided me to her entrance.
"Put it in, oppa. Take my first time."
At my sister's whisper, every thought I'd been clinging to guttered out like a candle.
Nothing remained but raw, primal instinct.
Squelch♥
"Kuh—!!"
The instant my cock sank into that tight channel, the first thing that reached me was a delicious, searing heat.
The walls welcomed me as though celebrating my arrival, clinging to me in a slick coat of arousal.
The sensation of her sheath molding itself to the shape of me.
Warmth.
A woman's sex cradling mine from every side.
It felt good. Overwhelmingly good. My hips shuddered of their own accord under the intense pleasure, and my mind floated off somewhere high above the clouds.
"It's finally happening… the joining of bodies with the one I love… my first experience with you. Our first copulation. Ahh… I think I could become addicted to this…!"
A voice that couldn't have been my sister's or the demon's murmured in rapture — but my floating head failed to grasp a word of it.
Starving for more, I tried to drive myself deeper — and felt something soft block the tip with a little bump.
Instinct told me what it was: her hymen. A moment's hesitation took root.
To stain, with the shape of me, something a woman had guarded her entire life — the thing she would remember until the day she died.
Squeeze.
"Oppa."
My sister wound her arms and legs around my frozen body and called to me.
"You're hesitating after coming all this way? Weren't you the one who wanted to break me?"
For the first time, my sister smirked as she said it.
I knew it wasn't sincere — that she was baiting the hesitant man inside her — and I fell for it anyway. There was no other way.
Thrust.
"Kuh!"
"Haaaaaaahh―――!!"
I drove in with every ounce of feeling I carried, and my sister's cry swallowed my groan and rang through the whole house.
The sticky smear of something on my tip let me push past what had stopped me, grinding up along her snug, unaccustomed walls.
The faint metallic scent of blood at the tip of my nose only stoked the fire higher.
The thrill of conquest — of conquering a woman, a being I had worshipped and hated with everything I had.
Fwuuut―!!
"Ah… th-that's… it, feels, go, good♥ I, it, ah?"
Just as I settled into a rhythm, my sister's body suddenly began convulsing like she was having a fit.
Eyes and body both careening out of control under something she couldn't contain. A flood of hot arousal burst from inside her, drenching my lower belly.
[Ah, th, uh… c, control… a w-woman's b-body's pleasure, control the sens— nghk!]
Even my sister's body was flickering in and out like static interference, and I stood there panicking, utterly at a loss.
But within seconds she had recovered her composure, smoothing her expression, her trembling body settling back to stillness just as quickly.
"I-I'm sorry! I ruined the mood, didn't I? The pleasure just hit me all at once and I couldn't control my body. I'm sorry, I'm truly sorry. Don't worry — I've got my senses completely under control now. So…"
The demon, groveling through tears of apology over the derailment, abruptly went silent.
Following my gaze, she rolled her eyes sideways to find what I was staring at — and realized I was watching the tears streaking down her own face. She grinned.
"It hurts, oppa…! I-it hurts… st, stop it… it hurts… I don't want this!"
"What— where did that come from…"
When the demon's face abruptly twisted into her sister's and the tears began to fall, I froze.
"Ow! Stop it, oppa… please…!"
"What? Ow! Wh-what is it? All of a sudden— d-don't move!"
Confused by the sudden reversal, I felt her palms slam against me, shoving at the body still joined with hers as she thrashed beneath me.
I caught her wrists on reflex to stop her, and her voice climbed.
"Nooooo――!! Don't!! Get away from me!"
"No! W-wait, just—! Quiet! Shut up, just—!!"
She fought harder the more I tried to calm her, until finally I couldn't take it and shouted without meaning to.
The moment I did, my sister beneath me flinched hard — then cowered like a frightened animal, turned her face away, and hid from my eyes.
A glance.
In that sliver of a second I saw my sister's eyes flick up, reading my expression in a heartbeat — and the corner of her mouth twisted upward, a satisfied smile surfacing and vanishing before I could be sure I'd seen it.
"Hyiiik! I trusted you… hic… I-I trusted you, oppa…!"
Looking down at my sister sobbing beneath a cascade of tears, I felt the thing that had gone soft inside her begin to swell all over again.
