Please Save My Sister's Pussy
"Please save my sister's pussy. Yeah?"
[Yoon Seojun's POV]
2 p.m. I had a free period on my schedule. Seo-ah said she was heading home. In the living room, I stared anxiously at the clock. She should be here any minute now.
From the Academy by car, it was a 20-minute drive. Exactly 16 minutes had passed since her call.
That's when it happened.
*Beep. Beeeep!*

The door lock went berserk, blaring like mad. "Sis!" I bolted to the entrance.
*Clack! Slam!!*
The door flew open as if it might shatter. "Hah... hah...!" Harsh, ragged breaths. Yoon Seo-ah staggered into the entryway. Sweat-soaked silver hair clung to her face. The front of her sweater was hideously torn and ragged.
*Slam!* No sooner had she shut the door than—
"Aaaah—!" A gut-wrenching scream erupted.
Her hands clawed frantically at her collar. *Riiip—!*
"Gotta get it off, quick...! Uwaaaah!" She shrieked in a frenzy, shredding the remnants of her sweater. "Pants... sob... why won't they come off..." Sobbing in terror, she yanked them down roughly. The fabric scraping her skin. It hit her brain like horrifying ecstasy. Her body twisted, hips bucking grotesquely with each spasm.
*Swoosh.* Her slacks slid down her ankles.
Was that the final straw? "Ah." A dazed sigh. Her head snapped back. Eyes rolled white. Drool dripped from her mouth. Her whole body went rigid, convulsing.

"Aaaaaaaah!!!!" *Squiiiirt—!* A fountain gushed out with her deathly wail.
"Sis...!" *Thud.* She collapsed to the floor. Stark naked. Had the sweat and fluids washed them off? No silicone patches in sight. Her juices bubbled and poured. *Squelch. Splorch.* Her lower half gnashed at the air. Hips bucked back and forth against her will. She crawled toward me across the floor. Her pale legs scraped red. *Slick. Squelch.* A trail of slime stretched behind her like a snail's path.
"Seojun... Seojun-ah...!" She clung to my leg, rubbing her flushed face against my pants, pleading. Her wine-red eyes, tilted up, unfocused and wild. Like a bitch in heat possessed by her cock-lust.
"A-alright. Calm down first, sis. Yeah?" I forced a nonchalant tone. If I showed panic, she'd freak out more. The first time, seeing me flustered sent her into full meltdown—bawling like a kid and pissing all over the living room floor. That poised, brilliant sister of mine, terrified by pleasure that bad. Unimaginable agony, no doubt.
I knelt swiftly between her splayed legs. *Spread.* She flung her thighs wide like she'd been waiting. Her pussy swollen to bursting. Her thin hymen quivered delicately. But the flesh around it churned out juices nonstop, like a well-worn whore's.
As always, I gathered my fingers. Thumb pressing her clit, index and middle teasing her entrance. *Squelch. Schlick, squelch.* Wet friction sounds. I lowered my lips, licking up around her clit. My daily ritual to pull Seo-ah from ecstasy's hell.
"Ngh... ah! There... hng! Aaah...!" Her hips bucked. She gripped my hair like she meant to rip it out. Ow... It hurt, but I didn't flinch. "Seojun-ah, sob, there too—suck harder."
Calming my terrified sister came first. How long did I work my hands and mouth? She should be cresting by now. But...
"Huh...?" Her body suddenly stiffened. Breath caught, hurtling toward climax but stalling.
"Hngk, u, uuugh...!" No orgasm. Just endless shivers. Something's wrong... I frowned, doubling down. Roughly parting her folds, sucking hard on the inner walls with my tongue. *Schlick, slurp! Splorch!*
"A-ah! Ahh! Hng...! Haaah!" She pounded my shoulders. Eyes rolled back white. Beastly foam at her lips. Not a lack of pleasure—there was too much. Shock-level overload. But it wouldn't break.
The cause? I learned later. That fucking magic tool had "evolved." The Mirror of Truth, twisting her buried love into heat. Now even fingers or tongue couldn't quench it. She needed the "real thing." My cock. Specifically, her little brother's. To tear her hymen, pound her womb, flood her with cum until it sloshed.
I didn't know yet. "No...!" She shoved my head away in frenzy. "Not that...! A-aaaah! I'm going insane...! I'll lose my mind like this...!" She screamed, breathless.
"A... aaaaaah!!!" Mouth gaping at nothing, terrified of some invisible horror. She clawed her skin until blood welled.
"Sis! Calm down!" Even I lost it, raising my voice. Fatal mistake—it snapped her reason.
*Plop.* Panting like a beast, she climbed atop me. *Grab.* Trembling hands seized my waistband. "S-sis?" *Rip!* Pants yanked down. Her hand dove straight into my underwear.
I loathed my arousal for her, but the thrill was undeniable. Already half-hard, she gripped it tight. "Fingers and mouth aren't enough anymore..." Tear- and drool-soaked breath hit my ear. "I'm dying here... stick your cock in me. Please."
Crude demand from my one-and-only family, the sister I'd leaned on all these years. I wanted to thrust in right then. But worry overrode lust. I had to ease her pain, her terror. But...
"...Sis." A memory flashed. The funeral home. Day our parents died together in the crash. The silver-haired half-elf holding child-me tight, swallowing sobs. Seojun-ah. My little brother. It'll be okay. Trust your sis. I'll take care of everything. Her quiet vow amid stifled tears.
Years later. Payday. She took me to an fancy steakhouse we could never afford, beaming. No blood shared, but family. My sister.
"Hold on." I pulled her hand away. She tumbled under the sofa. Wine-red eyes glared up, brimming with resentment. Even I felt tears rising. "Sis..." Still, I had to say it. "This isn't right."
I fixed my pants, gritting my teeth. "We can't cross that line. I'll find another way...!"
"...What?" Silence. Her shoulders quivered. Silver strands parted, eyes flashing. Sis...! A gaze never turned on me before. Despair. Hatred.
"You fucking bastard!!" A scream that tore my eardrums. Baring teeth. "After all I did raising you! I sacrificed my youth for you...!" *Slam!* Fist to floor, veins bulging. "I'm dying in agony here! My pussy's ripping apart! And you can't even do this?! You call yourself a brother?! Human?!"
First time seeing her true rage. But her naked body humped the air in heat. Each curse sprayed her juices like a fountain. "Ugh... ah...!" Rage fleeting. Womb-burning pain. Pleasure hammered her brain mercilessly. *Thud.* "Hngk, ugh...!" She crawled on knees, flattening at my feet. "Hic... kkh."
Wet lips kissed my instep. Tears and snot soaked my skin.

"Sis is sorry. Sis is all wrong, Seojun-ah..." Pitiful, broken plea. "Do whatever you want with sis. I'll do anything you say... I'm really gonna go mad..." Hands groveled, kissing nonstop. "Please save my sister's pussy. Yeah?" Desperate, dying voice. "Please fuck your cock into sis's pussy. Please..." Taboo-shattering beg.
Ranting madly, she suddenly bashed her forehead on the floor. *Thud!* "Aaaah!" *Thud!* "Ahng...!" Self-harm to chase the pleasure away. But her body turned even impacts to ecstasy. Each hit—*Splurt—!* Milky fluid gushed wildly.
I clenched my teeth. No one but me can do this. I had to save her. Morals be damned. Save her first. Resolved. Stood from the sofa. Shoved pants and underwear down. My rigid shaft sprang free. Convincing myself it was just for her. Though... I was excited too. "...Don't regret this." Gazed at her bloodied, pale face. Swallowing tears. "You asked for it." Shoving blame on her. Sorry, sis. Short apology in my heart.
"Please! Fuck off with that and just ram it in—!!" Desperate wail back.
Hands under her armpits. Hoisted her up, tossed onto the sofa. *Plop.* Spread thighs, knees to chest, pinned tight. Wide-open pussy. Foaming red mucosa. Intact hymen. Fine. If we're doing it, end it quick. Aligned my tip to her entrance.

"Agh, a-ah, q-quick! Seojun-ah! Please now...!!" She bucked wildly, grinding her slick hole on my shaft.
I thrust my weight in. Pierced her sealed virginity in one go. *Crunch—!* No foreplay invasion. My brutal length shredded her tight walls. Slammed deep into solid resistance. Her cervix.
"...!!" *Creak.* Her back arched like a bow. Joints screamed dangerously. Demonic spasm hurled her hips skyward. Shoulders dug into the sofa. Toes curled to breaking.
Unbearable foreign fullness and pain, first time ever. And... peak pleasure shattering layers of pent-up heat. Both slammed her brain at once.
"Oaaaaaaah—!!!" Butchered beast's howl. "Sis?! You okay?!" Panic halted me. Needless. She'd gone mad another way.
Just penetration, halted. Her womb hallucinated endless matings. Orgasms nonstop. *Shudder-shudder-shudder!* "Ah...! Ugh!" Eyes rolled white. Jaw clacked. Foam dribbled. Tear-soaked eyes. But lips twisted in grotesque bliss.

"Haaaaah! Hngk... hrgh...!" *Thud. Splorch.* Virgin blood from ruptured hymen mixed with white foam, staining the sofa. "C-come in... aaah! Nngh! Come iiiin...!" Trembling arms yanked my neck close. "Seojun's... little bro's... in my womb...! Aaaaaah...!!"
I didn't move. Still, she came repeatedly, squirting. Grip like it'd snap my shaft. Walls pulsed like mouths, chewing me relentlessly.
"C-cum... " Slurred tongue. "M-move... pwease..." Rolled-back eyes, drooling mess. Writhing tongue. Face twisted disgustingly. Beautiful sister's gone. Just fuckmeat that was once sis.
Taboo thrill. Pity. And conquest I hated admitting. All tangled, frying my brain electric.
"Got it." Gripped hips harder. "I'll give you what you want." Then pistoned my waist furiously. *Thwack! Splack! Squelch!!*
"Kyaaaaah—!! Good, so goooood—!!" My harsh grunts. Lewd slaps. Her agonized screams echoed without end.
