Sister's Temptation 1: "No Way... That One-Eyed Bastard?"
‘No way… that one-eyed bastard?’
He had footage he'd shot. He'd meticulously saved my phone number, and my fear that he'd use it to blackmail me had come true. With trembling hands, I checked the message.
It had finally come, just as I'd dreaded. I gripped my phone tighter. Sweat drenched my palm. My fingers wouldn't obey. After typing and mistyping countless times, I finally managed to send a reply. I'd comply with his demands, but I had conditions.
I held my breath and hit send. One second felt like a year. The reply came almost immediately.
My heart plummeted. He wanted me to do it while Hadojin was awake? That was impossible.
This was my final act of resistance. But he knew exactly where to strike my weakest spot.
I hurled my phone onto the bed. All strength drained from my body. In the end, I had to return to that hell. There was no choice.
His flippant reply filled me with a despairing premonition that this would never be the end. I collapsed right there and sobbed uncontrollably. But I knew crying solved nothing. He wasn't the type to show mercy...
Now, I had to create the stage, direct it, and act in it myself. Without exposing Hadojin's face. So no one would ever know my little brother Hadojin was involved in this filth.
‘Can… can I do this?’
Terror washed over me. But thinking of Hadojin's face turned that fear into steely resolve. My little brother, who threw himself into danger for me. The brave boy who'd gone to the company to negotiate with CEO Kim Gi-tae. Now it was my turn to protect him.
I took a deep breath and picked up one of the lingerie pieces scattered on the bed. The most provocative, the most lewd: a red silk slip. Its cool touch slid over my fingertips. I stood before the mirror. Slowly, I slipped off my bathrobe.
A stranger stared back from the mirror. A woman trembling with fear, yet with eyes that never looked away. A woman willing to offer herself as a sacrifice to protect the one she loved.
“Yeah… I'll do it.”
I draped the red slip over my body. The thin fabric flowed softly along my curves. My F-cup breasts, slim waist, and full hips were obscenely outlined.
“I'll… protect Hadojin.”

The woman in the mirror smiled faintly at me. It was no longer the smile of a victim. It was the smile of a warrior prepared for anything.
‘Huh?’
My left face is prettier than my right. A brilliant idea struck me. I opened my vanity drawer and took out an eyeliner. Under my left eye, at the tear duct, I dotted a tiny, distinct point. Small but sharp.
That single dot transformed the woman in the mirror into someone completely different. Not the rational, composed ‘Haruna’, but a seductive, provocative mystery woman.
“Yeah… this woman can do it.”
This was my armor, my mask. The ‘woman with the beauty mark’ would seduce her brother and drown in pleasure. ‘Haruna’ would merely watch as a spectator, protecting her brother.
I cast the spell on myself. It was the only way to keep from going mad. Finally, I whispered softly to ‘that woman’ in the mirror.
“Please… protect my little brother.”

…

Knock knock knock.
Late at night, I carried two bottles of wine and a cheese platter to Hadojin's door. My heart pounded louder than my footsteps. Thump, thump, thump. It felt like it would shatter my ribs and burst out.
“Hadojin, you up?”
“Nah, sis. Come in.”
The door opened, and Hadojin, leaning against his bed reading a book, looked at me curiously. Seeing his peaceful face twisted my guilt around my throat again.
“What's with the booze this late?”
“Just… gratitude. With the severance today, and I wanted another drink with you. You said you'd be my drinking buddy, right?”
I forced a bright smile and stepped inside. A lie. It was all a lie. I was here to hunt my own brother.
I set the wine and snacks by his desk. My fingertips trembled faintly.
“Ooh, nice! But you okay, sis? You drank a lot yesterday.”
“I'm fine. Tonight.”
I sat naturally beside him and poured the wine. The rich grape aroma filled the room. Even that smelled like blood to me. We clinked glasses wordlessly. The clear chime sounded like my death knell.
“What're you reading?”
“Oh, just… some academy stuff.”
“Studious as ever. Harina's been super pumped lately thanks to you. Says you're the best big bro.”
“Yeah?”
He smiled shyly. That innocent grin made me feel the full horror of my betrayal. But I couldn't stop. The one-eyed bastard's threats, the leaking video. Above all, Hadojin learning the truth. I had to prevent that.
Like the drinker I was, I paced it carefully, urging him to drink more. To hide my anxiety, I drank more and faster than usual. He, with his weak tolerance, soon flushed red and slurred.
“Hic… Sis… my head's… spinning…”
“It's fine. That's how you learn booze. Here, one more.”
I refilled his glass and drank with him. I had to get drunk. Sober, I had no confidence to pull this off.
The two bottles emptied fast. Hadojin was half-lidded, head lolling on my shoulder. His hot breath on my nape raised goosebumps all over.
“Sis… thanks… for listening… to me…”
“What're sisters for?”
His eyelids drooped; he yawned and started nodding off. I gently stroked his hair. The soft texture. Then, in a whisper only I could hear, into his ear:
“Sorry, Hadojin.”
He answered with steady breaths, sinking into deep sleep. I gazed at him for a long while. I laid him on the bed and caught my breath. Now the real show began.
I returned to my room and changed into my prepared outfit: red corset, fishnet stockings, heavy smoky makeup. The mirror showed a total stranger. And under my left eye, the beauty mark.
Now, I wasn't ‘Haruna’ anymore. I was ‘Haruna-with-the-mark’. The lewd woman who’d drown in pleasure to protect her brother.
Back in Hadojin's room, I carefully propped my phone on the desk. Angled the camera at the bed. Hit record—the red dot blinked on screen.
Stage set. Actors: me and my sleeping brother. Audience: anonymous shadows on that perverted channel...
I approached the bed and straddled him. Last night's memories revived, heating my body. I began undressing him. Firm chest, chiseled abs. His body was a perfect sculpture.
When I finally exposed him fully, I swallowed hard. The booze made it seem even bigger, more intimidating than last night.
I glanced at the camera. Imagined the bastard behind the lens. Then, defiantly, I kissed it.
“Ngh…♥”
Shame and arousal dizzied my head. Clumsily but desperately, I lavished it with attention. In my mouth, his sleeping member stirred back to life. That hot, hardening feel made my core clench.
“Haa… haa…♥”
Panting roughly, I mounted Hadojin. Like last night, I aligned him with my entrance. No hesitation this time. To avoid waking him, I muffled my sounds and lowered slowly. My pleasure-trained insides took him far easier than yesterday. No pain—just overwhelming fullness flooding my body.
“Hnnngh…♥”

The sensation of him filling me completely. I collapsed onto his chest, listening to his heartbeat. Steady, powerful thuds. Strangely, it calmed me.
I began moving my hips. Gently, silently. Focused on the slide of him inside me. Squish, squish. Wet sounds echoed in the quiet room.
I sealed his lips with mine, swallowing the noise. I felt his breath. His warmth. The fullness of becoming one brought tears.
This wasn't mere sex. It was my desperate struggle to protect him, a twisted expression of my love.
“Hadojin… I love you…♥”
Sobbing, I whispered in his ear. Then, his sleeping arm suddenly pulled me tight.
“……!”
I froze in shock. His eyes stayed shut, but his grip held firm. Half-asleep, he hugged me and shifted. I ended up pinned beneath him.
His massive frame crushed me. Our joined parts plunged deeper.
“Haaang!♥”
I stifled a scream, nails raking his back. Still mumbling in sleep, he buried his face in my nape.
“Sis…♥”
His sleepy call nearly stopped my heart. In his dreams, he was calling me. That alone absolved everything.
I wrapped my arms around his neck and surrendered to his movements. Instinctively, he started thrusting. Rough, primal—but laced with longing for me.
Plap! Plap!
The bed creaked amid our moans. Under him, I wildly bucked my hips to meet him. Shame, guilt, fear—all forgotten. Only the desire to unite with him remained.
“C-cumming…! Gonna cum…!♥ Hadojin…! Fill sis… inside… full…!♥”
I locked my legs behind him, squeezing tight. Then he erupted inside me.
Spurt, spurt, spuuurt!
Hot semen flooded my womb's depths. I convulsed in his arms, climaxing fiercely.
When it ended, he sank into deep sleep atop me. Feeling his weight, I gently stroked his back.
