The Twisted Save Zone

"The great me has arrived~! Yahoo, Orabang, I'm here!!"

Bursting through the door, Seo Harin struck a triumphant pose, hoisting a bag of chicken high overhead.

"Cooped up in ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠your room coding nonstop, you've turned into a total wreck~ But fear not! Your kind and loving little sister has personally delivered chicken to your doorstep!"

Harin dashed over to Hayun, who was seated at his desk, and plopped down right against him. It had been days since her brother locked himself away in game development, and she'd come craving both his attention and the chance to be the very first to try the game he'd made.

Hayun gave her clinging head a light thump and eyed her with weary disdain.

"Okay, okay, get off. The chicken smell is killing my focus. And by the way—you graduated high school last year, so why do you insist on squeezing yourself into that uniform every single time you come to my place?"

At that, Harin beamed as if she'd been waiting for exactly that question, scooting her chair right up beside him.

Her voluminous silver-white twintails swayed teasingly at the edge of Hayun's vision. Harin lifted one thigh slightly and drew the hem of her very short pleated skirt upward with a delicate tug, deliberately angling herself so that the line of her underwear peeked out from beneath it, then leaned her upper body deep into Hayun's space.

The buttons of her thin white shirt were stretched to their limit, straining desperately against the sheer mass of her swelling chest, while her black tie lay buried in the deep valley of her cleavage. Harin narrowed her playful purple eyes upward and pressed her index finger lightly against her red lips, letting out a coquettish little whine.

...She's got the kind of face and body that could get called a beauty anywhere on earth, and of course she had to be my sister. We share blood—there's never going to be anything between us—so why does she keep doing this to me?

Swallowing his bitterness and resignation, Hayun quietly averted his gaze. Oblivious to what was going through his mind, Harin pressed on in a whining, wheedling tone.

"Aww~ Orabang, you're asking because you don't know? A little sister's schoolgirl look is always the supreme dignity reward! If I dress up like this for you, won't our shut-in coder oppa's poor starved eyes get a feast and his development motivation shoot right back up? Am I right or am I right?"

Then, making the excuse that her skirt was too tight and stuffy, Harin did something outrageously bold—she slid her underwear slowly down beneath her skirt. Peeled off down to her ankles, the panties were plucked free and quietly set on the floor beside the chair, after which she smoothed her skirt back down with a mischievous expression. Hayun's gaze dropped to the underwear on the floor. When he saw that the crotch was faintly, damply wet, he flung his eyes into empty space, barely containing his flustered panic. Turning his head away and pretending not to have seen, he tossed out a single remark.

"You... are you actually out of your mind? Even if this is home, who takes their clothes off and just leaves them lying around like that? You've completely lost it."

"Hehe, don't know~! What can I do, it's stuffy? It's just Oppa anyway, so who cares~"

Harin stuck out her tongue and giggled, then hopped up onto the chair, completely forgetting to pick her panties back up off the floor.

"Oppa, this is finally the first playtest, right? I thought I was going to die of boredom these past three days! You should feel honored—the world's cutest Tester No. 1 is graciously going to play your game for you!"

Hayun forced his gaze away, trying hard to ignore the damp panties left abandoned on ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the floor beside his chair. But beneath the short school skirt, bare thighs untouched by any underwear and their smooth curves flashed across his field of vision. The intimate crease of Harin's now panty-less body, glimpsed at the very edge beneath her skirt, kept dragging his eyes back against his will. Struggling to steady his pounding heart, Hayun forced out flatly:

"Fine. I was just about to run the first test anyway. Grab the mouse."

"Okay! Keep your eyes glued to me and watch closely, Hayun oppa! Just don't freeze up when you fall for my flawless control, got it? Hehe, here I go~!"

It was the exact moment Harin—her lower half still completely bare—seized the mouse and pressed the game's start button.

The unfinished adult special-mode script collided with the Save Zone computation code, and the monitor screen froze solid. A heartbeat later, space itself warped and swallowed both their consciousnesses whole.

"...Ugh!"

Hayun's eyes snapped open to a vicious wave of nausea. But his line of sight sat far lower than it should have, and his entire body's center of gravity had collapsed into something alien.

"Ugh... Harin, are you okay...?"

The moment he opened his mouth, what came out was not a man's rough voice. It was a thin, fragile, delicately cracked woman's voice.

"Huh...? Why does my voice sound like this?"

Panicking, Hayun hastily brought his hands up before his eyes.

They were not the hands of a man—callus-hardened, thick-boned. The fingers were long and pale, each joint slender and delicate.

The moment he tried to push himself up, a bothersome weight and a heavy pressure settled in around his chest. He hastily dropped his gaze downward.

Beyond the dark-toned, suggestive dress, two masses of breasts—swollen so grotesquely enormous they blocked out his entire lower field of vision—pressed down heavily against his chest. Along the boldly plunging neckline and shoulders, asymmetric tan lines remained, unmistakably the shadow of some previous outfit. Against the exposed skin of the darkly sun-tanned dress, the porcelain-pale flesh standing out in stark contrast made the already gigantic breasts look all the more surreal and obscene.

Hayun stared down at his own chest in disbelief, then reached out with trembling, slender hands and rested them gently on top of his breasts. The overwhelming volume—more than a whole palm could hope to cup—along with the impossibly soft, pillowy flesh that yielded around his fingertips, transmitted itself vividly through his skin.

"Wh-what is this...?"

When he clenched his fingers and pressed down hard, the dense breast flesh squished and deformed, spilling out between his fingers—its softness and texture rocking Hayun's brain to its core. When he lowered his head further, he found a flawless, smooth white leg fully exposed through the long slit of the dress that ran up past his thigh.

A chill ran down his spine the moment he realized: his body was the body of an adult NPC, built for ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the sole purpose of filling someone's desire.

"This can't be real...?"

Hayun's hands began to shake. He thrust one hastily beneath the torn slit of the dress.

It was gone.

The part of him that had existed, unquestioned, for his entire life as a man had vanished without a trace. Instead, what greeted his fingertips was the sensation of a delicate slit—a fine cleft he could just barely part. Where his cock should have been, the entrance of a pale-pink virgin pussy that had never once taken a man clung to his touch, impossibly narrow and maddeningly tight.

"Where did it go...? Where is mine?! This is insane, this is insane!!"

As if to deny his identity as a man, Hayun cried out while rubbing and groping at his untouched, never-before-used virgin pussy—not a single drop of arousal pooling there yet. His dignity as a male shattered in an instant, and a cold-wave terror wrapped itself around his entire body. This was the result of the system forcibly overwriting unused NPC dummy data onto Hayun's soul as he was transferred into the game he himself had created, Arcresia.

But before he could even begin to process the despair of losing his original body, a far greater terror crashed down upon him.

"Haah... haah... Oppa... pussy... Oppa's... pussy..."

Above the head of Seo Harin, who was pinning Hayun down from above, a red system message was displayed.

Harin's unfocused eyes, corrupted by the patch, had lost all reason and gone berserk—and yet she seemed to know exactly who was lying before her. Swallowing her saliva, she stared intently at the pussy that Hayun's body had become—its pale-pink lips trembling shut so delicately, its narrow hymen holding on so pitifully—and her gaze brimmed over with nothing but the primal, instinctive hunger to impale and devour her brother's pussy.

Beneath Harin's flushed lower garments, a grotesque bodily transformation utterly unlike her usual self began to reveal itself. Above Harin's own pussy, a thick, elongated cock had sprung free—bluish veins throbbing and writhing in a way that turned the stomach.

"H-Harin...? Don't come closer... please, don't!!"

Acting on instinct, Hayun cringed backward, trying to scramble away.

But the instant he pushed himself back across the ground with his hips, retreating in a panic on his fragile, delicate woman's legs, he pressed his palm down too hard against the coarse dirt and gravel scattered across the floor.

"Agh...!"

Sharp grains of gravel raked roughly across the soft, white skin of his palm, gouging out tender bits of flesh.

Along with a vicious sting, bright red blood began to spread across the surface of his palm. A pain exquisitely sharp and cruelly unfair—something he had never felt in his days as a man—burrowed stinging from the tips of Hayun's fingers up into his skull. While he faltered from the pain, he raised both hands to shove the approaching Harin away, gripping roughly at her broad shoulders and chest, but between the searing ache of his shredded palms and the frail strength of his woman's arms, he couldn't budge his maddened sister's weight even a little.

Harin's strong hand snatched Hayun's wrist and pinned it to the ground. Hayun twisted his body with all his might, but the moment he felt Harin's rigid cock rubbing against the entrance of his own never-once-penetrated, virgin pussy, his mind went blindingly white.

"I-I'm sorry... Oppa...! Hnngh, ugh, haah, I'm so sorry...! But... I can't hold back...!"

Even as Harin burst into wracking sobs, her face smeared with tears and snot, her hips drove forward more violently than they ever had before. Harin's cock bored into her brother's pussy without mercy, as if to rip it apart, and Hayun's delicate body bounced off the ground.

"Aaagh! Not there, please!! Stop, I said stop!! Have you lost your mind?! To your own brother!!"

Within the twisted reality of his own creation, Harin's massive cock took aim at the entrance of Hayun's untouched pussy and bore down.

Schlooock—! With a wet, squelching sound, the massive glans pried its way forcibly into the slickened folds and, still rigid and hard, tore straight through Hayun's pale-pink virgin entrance in one thrust, driving all the way to the deep entrance of the womb.

"AAAAAHHH——! Harin, I'm dying, please stop... hnggh, uuuugh! It hurts, no, I'm tearing—please pull out, PULL OUT!! HYYYYAAAHH, Harin, please, save me, really, don't do this...!"

The narrow vaginal walls—walls that had never once given permission—were mercilessly ripped and stretched in every direction, and at the thick sensation of the cock forcing its way to the mouth of her womb in a single stroke, Hayun flailed his whole body wildly, spilling tears and snot. Even through the searing burn of it, this newborn NPC body of this world had flared up to an unnatural, extreme sensitivity.

Every time Harin's cock buried itself completely to the hilt and pounded against the cervix—thud, thud, thud, thud—a convulsive current of unbearable pleasure shot through Hayun's entire body alongside the agony that pierced his brain.

"Aahhnn, uuuugh! Ah, ahhn...! No, stop... it's tearing, my pussy's tearing apart...!"

Unable to endure the stimulation, hot, sticky nectar burst out from Hayun's crotch again and again, spraying in every direction—schluuuush—

A violent squirting seizure wracked her, as if every drop of moisture in her body were being ejaculated through her pussy, and the massive flood that erupted soaked Harin's white body, her enormous breasts, and even her face without mercy.

Her exquisitely sensitized pussy, wound tight toward climax, kept spattering nectar in every direction without pause, soaking the ground; and Hayun, overwhelmed by the flood of sensation, thrashed with her eyes rolled back, utterly lost.

Please... let it end, please, let it end soon and just kill me instead...!

She wept, desperately wishing for nothing but for this nightmare to end—yet cruelly, her body could not overcome the pleasure, trembling as the walls clamped down tighter than ever.

"Haaaahn! Agh, why is Oppa's pussy so hot and tight... I'm losing my mind, I think I'm actually going crazy...!"

The moment Hayun's pussy clamped down with such intensity, so lewdly tight, Harin lost herself to pleasure, her eyes rolling back as she panted raggedly.

"Hngh, no...! I'll fuck you faster, deeper...!"

Smack, schlap—! Thwack, thwack—! Harin, driven mad by the feel of the narrow, scorching tunnel clenching around her without mercy, multiplied the speed and force of her thrusts several times over, pounding Hayun's womb—thud, thud, crunch, crunch—hammering into it like a woman possessed.

The lewd, splattering sound of nectar and bright-red virgin blood mixing and slapping together rang out through the forest, and thick, hot, cloudy semen gushed from the base of Harin's cock, pouring in waves into the raw, churning depths of Hayun's tunnel.

The excessive volume of semen could not be contained; it overflowed from the seams of her pussy in a steady stream, soaking Hayun's thighs and buttocks white, while the sticky, pearly fluid and nectar splashed upward together, dyeing Hayun's vision and cheeks—and Harin's belly and thighs—completely white.

When the storm of it had passed and the runaway surge of mana subsided, the red glow slowly drained from Harin's eyes. Lucid again, Harin reached out a hand, apologizing through her guilt—but Hayun coldly rejected her touch.

"...Don't touch me. Keep your hands off."

A heavy silence settled between them, and before the pain had even begun to fade, a massive tremor shook the entire forest—and out of the darkness, the enormous boss monster, the Ogre, came crashing in.

"Eeek...! KYAAAAAH—!"

The crushing presence of the boss monster appearing out of nowhere—and the cruelty of her brother's harsh words still ringing in her heart—left Harin paralyzed with terror; she trembled violently, warm urine soaking out from beneath her skirt.

Hayun, his vision smeared with semen so he could only dimly grasp the situation, lifted his head in horror—and in that instant, the Ogre's colossal club fell carelessly down upon Harin, who stood frozen in panic, unable to do anything at all.

KUUUUNG—!

When Hayun turned around, what met his eyes was Harin—her bones and organs burst apart, dying in unspeakable agony. Fresh blood spattered across the damp soil. Vomiting, consumed by terrible fear and revulsion and the crushing despair of having caused his sister's death, Hayun fled into the forest.

For three days, Hayun could barely walk. Every time he closed his eyes, Harin's gruesome final moments played before him. And then he came face to face with the forest's apex predator, the Harpy Queen—and its blade-sharp wings severed his head from his neck.

Death is easier... this hell is finally over...

Fwooom—!

Time and space rotated in reverse.

"HYYYYAH—?!"

When he opened his eyes, he was greeted by the damp scent of the forest and an alien weight pressing down on his chest. Hayun's eyes wavered. It was a familiar place. And the Harin before him was familiar too.

"Haah... haah... Oppa... pussy... Oppa's... pussy..."

Hayun's breath caught. He had returned. Harin—who had been dead mere moments ago—was lunging at him again, still stained with that same nameless madness, intent on violating him.

"N-no... don't come... Harin, please...!"

Hayun struggled desperately to push her away with his trembling woman's hands. But even after the regression, his frail NPC body was no different. Her iron grip seized his wrists, and once more his limbs were pinned mercilessly to the ground.

"Oppa... I'm sorry... haah, I'm sorry...! But... I can't hold back...!"

"Stop it! I said stop!! You crazy bitch, let go! Let GO, I'm your brother!!"

Hayun tried desperately to scream the truth—but every time the horrible facts tried to burst out of his throat, some unknown constraint of the system crushed them down, muffling them into something strangely shapeless.

The harder he tried to force out the words I remember everything from before the regression, the more his tongue tangled and his breath choked off; between his lips there escaped nothing but miserable screams and whimpering, resentful babble. A cruel shackle sealed Hayun's mouth shut—wanting to speak the truth, yet utterly unable to.

And in the meantime, Harin's grotesquely swollen, throbbing cock pried its way without mercy into Hayun's narrow, defenseless pussy.

Schlooock—! With a wet, squelching sound, the massive glans pried its way forcibly into the slickened folds and, just as before, tore through the narrow vaginal walls this life had never once offered to anyone—ripping them open without mercy and skewering her straight to the entrance of the womb in a single stroke.

"KYAAAAAAH! Harin, I'm dying, ugh, please stop... HYYYAAAHH!!!"

The hymen was ruptured once more. At the tearing, flesh-rending agony, Hayun flailed his whole body wildly, spilling tears and snot. Even through the vicious burn, this newborn NPC body flared up to an unnatural, extreme sensitivity.

Every time Harin's massive cock pressed down against the cervix—thud, thud, crunch, crunch—and bored mercilessly into the depths of her tunnel, a current of pleasure that pierced Hayun's brain shot through her entire body.

Even amid the unbearable pain, her sensitized body surrendered completely, convulsing into one squirting spasm after another—schluuush—spraying nectar in every direction, the juices drenching Harin's chest and face entirely. And Harin, who had faltered for just a moment, lost herself completely.

Amid the violent pounding of her hips, Harin growled like a beast and seized Hayun's enormous breasts without mercy in her delicate, white, and yet so terrifying hands.

"Agh——! Ah, please don't squeeze so hard there...! My chest's going to burst, it hurts...! I said it hurts, you crazy girl, it hurts so much I could die!!"

It was the touch of a frail, girlish hand—yet the hands crushing down on Hayun now felt more cruel and more terrifying than the claws of any monster. As Harin bore down on and roughly gripped the breasts of such overwhelming volume that her fingers couldn't even close around them, a dull agony of tender ducts and soft skin being crushed flat, along with a burning heat that felt like tearing, lanced through Hayun's upper body.

Damn it... these are a woman's hands, just my little sister's delicate little hands... and it fucking hurts! My breasts feel like they're going to tear apart! This crazy girl is seriously dangerous!

Along with an extremity of pain he could never have imagined in his days as a man, the wretched realization struck him like a blow to the brain: he had fallen into being a woman several times more fragile and helpless than the little sister trampling his body beneath her.

Hayun screamed through his tears and snot; the tears streaming down his cheeks spread hotly, then quickly dried stiff in the cold air, leaving rigid white trails of dried tears across his face.

It hurts... it hurts... it hurts so much...!

Like a bitch endlessly crushed beneath the little sister violating her, her frail body quivered and thrashed without reprieve. But Harin paid no heed, gripping the breasts even harder, kneading and shaking them as if to grind them flat.

Hayun howled in pain, his whole body writhing. Yet cruelly, his body surrendered wholesale to the pleasure, clenching around Harin's cock ever more lewdly—and the tighter it gripped, the more completely Harin lost her mind.

Squelch— squelch— shlop— shlop— The lewd sound of sticky fluids churning and spilling out where the two bodies joined rang out shamelessly through the forest. Matching the storm of hips slamming hard enough to crush the ceiling of her womb, Hayun burst into repeated squirting spasms, spraying hot nectar in fountains in every direction.

"Oppa, Oppa...! Why is Oppa's pussy so damn tight, I'm seriously losing my mind! It's okay if I cum inside, right? I—I think I'm gonna cum inside you...!"

"No, please! Are you insane?! Don't cum inside, I said DON'T!! Stop, pull out, PULL OUT!! KYAAAAAH——!"

Harin, as if gone completely mad, crushed the womb—thud, thud, crunch, crunch—and drove her hips even faster and harder, ramming into her without pause. Then, panting, she looked down at Hayun with glistening eyes and abruptly spoke.

"Oppa... it's okay if I kiss you, right? Mm, that's permission...?"

Giving him no chance to refuse, Harin bent down and crashed over him, roughly crushing Hayun's lips beneath her own. With a tongue that stole his breath away, she ransacked the inside of his mouth, mercilessly robbing him of his first kiss.

Shlop— shlop— slurp— slurp—! Their lips tangled together with a wet, obscene smacking—and at last, from the tip of Harin's cock, pushed past its limit, boiling-hot pearly semen came surging out—bbrrrrt, bap, brrt, bap—!—with rough, thunderous force, slamming into the depths of Hayun's narrow tunnel and striking squarely against the firmly closed mouth of her womb, pouring in wave after wave.

The hot semen that Harin's burning cock pumped out as it drummed against the walls of her womb filled up the front of Hayun's delicate womb as if to grind it flat. Under the weight and crushing pressure of the pearly fluid damming up against her cervix, Hayun's eyes rolled back and her breath stopped in a shock like her heart seizing.

Under the aftermath of terrible pleasure and rape, Hayun's legs went utterly limp and collapsed downward; the inner muscles of her thighs—forced apart and stretched far beyond their limit—ached dully and visibly quivered.

The semen her womb had no room left to contain pushed stubbornly up against the walls and spilled in streams down the inner walls of her tunnel; with every violent slam, the sticky seed pooling inside and the nectar gushing out mingled and surged back out through the seams of her pussy in sudden, wrenching floods. The overflowing pearly fluid soaked Hayun's limp thighs and buttocks white and sticky through, and splashing in every direction with a wanton, swaying sound, it dyed her vision and her cheeks—and Harin's belly and thighs—completely white.

"Oppa... I'm sorry..."

Hayun did not answer.

Harin reached out a hand, cautiously.

In that instant, Hayun's body flinched.

Harin's hand stopped dead.

"......"

"Don't touch me."

Hayun's voice had sunk low.

"Keep your hands off me."

Harin slowly lowered her hand.

"...Okay."

Once again, a heavy silence settled over the two of them. Hayun hung his head.

His mind was still a tangled mess.

Anger, shame, terror—nothing would settle down. Not one of them.

The only thing that clung to him, stubborn and unshakable, was the fact that what had happened to him was real.

Within the raw, swollen junction of their bodies, Harin's cock slowly caught its breath, its volume gradually shrinking.

"Haaah..."

The moment the heavy, plastered-together sexes slid apart, the white semen packed inside her came gushing out in clumps through the gaping, loosened lips of her pussy, streaming down in a thick ribbon.

From the slackened, gaping entrance that could no longer close, the pearly fluid splattered to the ground with a slick, gurgling sound, and a raw, flesh-torn numbness—and an aching emptiness—swept through every inch of Hayun's body.
