The Sister Who Broke
My younger sister was crying. The sister who had lived her whole life wearing nothing but an angel's smile. The sister who, from the time we were children, I had never once seen angry or irritated or in tears — always so grown-up. The sister who, in any situation, stayed calm and walked the right path, blazing brilliantly. As that noble, flawless being crumbled before me and showed me tears for the very first time, my blood boiled again, and that heat swelled without limit.
"Do you... trust me?"
A smile surfaced. Her voice carried fury and a chilling coldness, and yet, contradictorily, her lips were full of smiles.
"Eek! O-Oppa...?"
Watching my sister look up at me with an expression soaked in fear, my sadism shot skyward. The submissive posture of a being who had once been superior to me — a distant presence I had never dared to covet — made a sense of dominance swell inside me. The fact that a demon was performing a role was nothing more than a passing thought. This being had my sister's exact body, voice, and personality. Was there any reason to think deeply about it?
My hands moved slowly toward my sister's throat. The motion — impossible to call a first — came out with terrible naturalness. My sister watched the shadow fall across her own face with trembling eyes, and when she tried to resist, I swiftly seized her neck with both hands and squeezed.
"Kkh—!"
A last-gasp sound burst from her twisted throat. Strangled, she thrashed inside my arms in the pure instinct to survive. She fought back, but feeling how feeble her strength was, I realized with sudden clarity that my sister was nothing more than a mere woman.
She made choked, guttural sounds as her breath failed her, her face slowly flushing red. Her tongue slipped past her lips, and drool leaked out between them. As every muscle in her body tensed, the channel gripping me contracted reflexively, tightening hotter and hotter around me.
Watching that noble face collapse into ruin, I understood at last that my sister too was just an organism assembled from blood and flesh, bone and muscle. No different from any other human — a creature with a hunk of meat for a body that dies when strangled, dies when stabbed or shot. The moment I thought that, my sister's existence seemed pathetically cheap. And at the same time, the thought that I could do anything I wished with the being who had always outshone me sent a feeling of omnipotence spreading upward, and a tingling pleasure surged.
In a word: It was the best I had felt since the day I was born into this world.
"Sa- Save me, kk—!"
Her face turning a deathly blue, her body shuddering, her eyes rolling back as she slipped gradually toward unconsciousness — and I snapped awake in shock. My consciousness, which had become someone else entirely, returned with lightning speed.
"Ah!"
"Kkhh!! Kkhooaak—!!"
I— what did I...? The instant I released my hands, my sister coughed violently, again and again, pure reflex. Looking down at her, I realized that I had nearly killed a human being. A wave of dread washed over me. I felt like I had become... not myself. It was as if... I had been possessed by some demon.
Through my trembling fingers, my eyes met my coughing sister's. Her face was clearly wracked with agony, but strangely, the awareness in her gaze — the way it searched my own complexion — seemed oddly lucid.
"Are you oka—"
"I'm- I'm shorry, oppah! Oppa, I'm sorry!! P-please, shpare me!! I'll do anything! Anything you want, oppa, I'll do it...!! Pleathe... tho pleathe—"
Before I could even ask, my sister preempted me, tears pouring down as she babbled in a shaking voice. She looked at me with the same expression of terror and dread as before, but the meaning was different now. At first it had been rage and defiance; now she was groveling, crouched low, watching my every mood as she pleaded.
"I'll do anything... oppa, please spare me... I'll... do everything... you tell me to...!"
My sister, begging so abjectly, rubbing her hands together to the point of humiliation. Watching her — so desperate to survive this instant that she seemed to have already forgotten what I had done moments ago — my guilt snuffed out in a heartbeat. For this broken thing that had been my sister, it felt like anything I did would count as absolution.
Heh... In that moment, a low chuckle drifted from somewhere, brushing past my ears like tinnitus. My sister — obscenely scattering every possible fluid from her face, tears and snot and all — no longer looked pretty to me. Her beauty remained, but her essence seemed stained now, and she no longer blinded me. Soiling something once soiled is no difficult task. Dropping a bead of ink onto a blank white page breaks your heart; splashing more ink on after that is easy.
"Laugh."
"He... hehe..."
I commanded it with contempt and derision, and my sister forced the corners of her mouth upward into an unnatural smile. It was a thoroughly cringing, repulsive little laugh. So the great miss herself knows how to smile like this...
"Pathetic bitch..."
Heh heh... No guilt remained. It astonished me that I had ever held such feelings for a creature so ugly and so filthy.
Slish... When I pulled myself out of my sister's body, a viscous slick of fluids stretched from her in tangled threads, clinging to my length before dripping away.
"Ah..."
A short, wistful sigh escaped her — and when I looked, my sister was staring at me with a terror-stricken face.
"O- Oppa...?"
"Open those legs and take it. If you don't want to die."
"Y- yes!"
I lay back and gave the order coldly, and my ever-quick sister scrambled up and straddled me, spreading her legs wide like a crab, lining her hole up against my length as it stood rigid. My sister, splaying herself in a whore's lewd open-legged pose, looked utterly cheap.
Squeak♥
Mmm... My sister, lowering her hips and taking me back inside, was still as pleasant and snug as before. It was the first woman I'd ever known, but even a total novice like me could tell my sister's depths were something exquisite.
"Oppa? How's my body? Do you like it?"
My sister asked, watching my face while flashing a servile little smile.
"Yeah, fucking love it. Whoever made this body really knew what they were doing. Your face, and your pussy too."
Reaching up where I lay, I toyed with her beautiful breasts like a plaything. A chest I had once only ever dared to imagine touching — and now I was mauling it without a second thought. Another wave of delicious pleasure surged through me.
"Hehe... good, that'sh a relief. Then... you'll spare me? You'll let me live? You won't... hate me...?"
My sister kept giggling nervously, her eyes flicking constantly to my face.
"We'll see."
"Yeth... hehe! I'll work hard... I'll make you feel good, oppa!"
Squeak... My sister rode on top of me, bucking her hips. Pleasure came flooding in with every movement, like a rising tide. She was awkward at first, but just as she had been first in sports and first in her studies, she swiftly mastered the craft of sex.
Squeak, squeak♥
"How's this, oppa? Feels good? Should I move my hips more?"
Perhaps gaining confidence, her movements grew faster and faster. The intervals between the wet, slapping sounds of flesh meeting flesh narrowed too. Honestly, it felt so good I wanted to come right that second.
"It's okay, oppa! Do whatever you want! You can come inside me! No — please come inside me! I want you to cum in my pussy, oppa! Please, oppa! I'll take all the responsibility, so please, please cum inside me!!"
As if reading my mind, my sister raised her voice. As the moment of climax drew near, my sister wore a contradictory expression — smiling through her tears. Delighting in pleasure even as sorrow showed on her face, the demon and my sister overlapped in her features all at once. At that depraved spectacle, the climax I had held back and held back surged up from below.
Spurt—!
I couldn't hold it any longer, and I finally released the hot liquid. This time not into a mouth, but into a woman's channel, where semen could serve its true purpose. I could feel the erupting fluid seeping deep into her quivering depths. Her channel clamped down on me to its very limit, trying desperately to milk out even more. It gulped down my semen greedily, hungrily, as if to consume it. The heat swelled, and to take my seed as deep as possible, her fluids gushed out without pause, slicking the way.
"Nngh..." Floating as if in the sky, my consciousness and vision going hazy — and through that blur, I saw my sister cupping both her cheeks in her hands, lost in rapture.
"Semen. Dohyun's semen... ahh... the seed that makes a baby... it's mine, this is mine alone. It's beyond precious. The most valuable thing in the world... I'll treasure it forever." My sister gently stroked her lower belly as if a baby were already growing there, a smile full of maternal love spreading across her face.
"Give me more... your semen. It's not enough, still not enough. Pour more of your love inside me."
Through my dazed, lingering haze of climax, I watched some being wearing my sister's face cup my cheeks in her hands and speak to me, burning with heat.
"Pleasure? I'll give you more. What kind of pleasure do you want? Or do you want something else? As long as I can have what's yours, I'll do anything. I can give you this world. If only I can have your love, there is nothing I won't do!"
My sister — no, the demon — pressed her face close and looked down at me, whispering.
"Give me more. Your love. It's still not enough."
I couldn't answer. My languid body had no will left to move my mouth.
"I see... you're very tired right now. A shame, but it can't be helped. Human flesh is so fragile." The demon spoke with regret and stroked my hair.
"Don't worry... we have endless time, you and I."
Smooch. A hot sensation touched my forehead, and was gone. All the while, my consciousness was racing toward its end.
"Look forward to it. I'll wrap you in so much more pleasure. There's still so much left for you to enjoy, isn't there? In exchange, all you have to do is give me your love. ...My love. Even the way you sleep is adorable."
Sliide. Through my drooping eyelids, I saw the demon gazing at me, her face flushed red. I didn't know what the demon's "more pleasures" or "things to enjoy" would be, but nothing about them felt like they would be normal. And yet I no longer seemed capable of refusing. Because I had learned now that the pleasure and happiness the demon gave me were sweet beyond all resistance.
