The Mysterious Man
Jin-seok's goshiwon room was less a human dwelling and more like a beast's den or a massive trash bin congealed from rotting desires. The mountain of instant ramen cups piled everywhere reeked of sour food waste, and the narrow, unventilated space was thick with stale cigarette smoke soaked into the wallpaper as yellowish grease stains. The only sign of life in this windowless hole came from the pale, eerie glow spilling from the monitor on his desk.
He was an unknown writer scraping by day to day, serializing third-rate erotic web novels under the pen name Ma Gangdu instead of his real name, Jin-seok.
"Look at these shitty views... Readers these days are so damn picky. I wrote it this explicit, they should at least unzip their pants, right? All talk, no action."
Jin-seok flicked away the dandruff from scratching his side and glared at the monitor. That day, he'd gone to the Amusement Park for the most vulgar, primal reason. His material for the next story had run dry, so he'd planned to sneak some voyeur shots of blissfully smiling couples and defile their innocent lives with his perverted imagination. Hiding a cheap secondhand camera in the pocket of his baggy windbreaker, he'd prowled the crowds like a hyena—until he spotted a gleaming latest-model smartphone on the asphalt, like fate itself had dropped it.
It wasn't just dumb luck. It was a devil's gift hurled to him from the abyss.
Back in his goshiwon, Jin-seok plugged the hot-found phone—stolen goods, basically—into the charger with trembling hands. The black screen flickered to life, but what appeared wasn't a normal wallpaper. It was a bizarre app with a red shutter icon, and beyond its glass wall, Siyeon trapped and screaming in agony.
"What the hell is this? Some new voice phishing scam? Or some cutting-edge interactive game?"
At first, Jin-seok thought it was just an ultra-realistic AI character built from photorealistic graphics. But curiosity led him to tap the [Character Sheet] tab at the bottom, unleashing a endless scroll of stats too detailed for human logic.
The woman inside the screen flinched at his gaze alone, scrambling backward into the corner. Beyond the glass wall: tears pooling in her eyes, her slender shoulders trembling in terror, the red blood at her fingertips from desperately pounding the barrier. Every texture was chillingly vivid. Jin-seok brought the phone close and sniffed it. Amid the faint plastic scent, he could've sworn he caught a strangely sweet whiff of flesh.
"Please, save me! Is anyone there? Please, let me out! Jihun! Oppa! Can you hear me? Please..."
The scream bursting from the speaker was pure, unfiltered human voice—no synthetic edge. It carried desperate longing for her husband and instinctive revulsion toward this stranger. Jin-seok swallowed dryly. His twisted desires began to stir. He spotted the translucent box at the app's bottom: [Author's Note: Setting Modification]. Forbidden fantasies poured onto the keyboard.
Siyeon's surroundings heat to 40°C instantly. Dress lining turns to rough burlap sack. Stimulation increases sexual arousal proportionally.
The moment he hit Confirm, Siyeon's pale skin flushed beet-red, like she'd been doused in scalding steam.
"Ahh... So hot, too hot...! Haa, haa... Can't... breathe...! Oppa... I'm burning up..."
Siyeon clawed at her slender neck, gasping raggedly. To make matters worse, her soft floral dress morphed into a burlap sack bristling with thousands of sharp thorns. Every twitch scraped the rough fibers mercilessly against her sensitive white skin.
"It hurts, it hurts! Why is this happening?! Please stop it! Anyone, please... Ngh!"
Each drag of the coarse fabric over her swollen breasts and crotch brought agony—and a strange physiological response. "Nnghaaa❤️... My body... what's wrong... Wh-what did you... do to meee❤️"
"No matter how many times I watch, it's fucking amazing lololol. This is fun."
Jin-seok's eyes gleamed with madness. This wasn't just a game. This smartphone, this grotesque app—it was a God's Pen, a living manuscript that manifested every typed delusion onto real flesh.
And in that sealed prison, the world's most noble beauty begged for her life and dignity at the mercy of his fingertips alone. Jin-seok grinned, yellowed teeth flashing through his scruffy beard. He swiped roughly through the phone's gallery, full of Jihun and Siyeon's loving wedding photos. Siyeon's radiant smile, nestled in Jihun's arms, the happiest woman alive. A thick glob of Jin-seok's yellowish spit splattered across Jihun's beaming face.
"You're just ink on my manuscript now. I'll rip apart that precious chastity of yours, piece by piece, right in front of the man you love most. That bastard won't even get to watch you break."
"No!! Nghhh...❤️ My oppa... he'll find me for sure. He won't let a creep like you get away with this, I swear—just wait a littleee❤️"
"Oh yeah? Even better if he does lol. I'll etch every moment of your body and mind getting remade right into his eyes."
"Now, where should I start playing with you lololol."
All those lowbrow, sadistic lines he'd hammered out in his corner, fueled by nothing but imagination and pitiful views, now cascaded through his mind like a waterfall. Jin-seok no longer needed to prowl outside with a camera. This palm-sized smartphone held the world's perfect subject—a living doll to absorb every filthy desire.
He toyed with Siyeon until she collapsed in exhaustion, testing the system's limits. And then,
Jin-seok sat before the cold monitor, logging into his familiar site. He posted a new series announcement. His clicking finger trembled with ecstasy. His erect cock strained against his worn sweatpants.
Ultra-Realistic Hardcore NTR Masterpiece Begins Serialization!
Author's Note: This heroine is special. She's real. She reacts to what I write, breaks to how I set her. Stay tuned.
Jin-seok propped the phone under the desk lamp's harsh glare. The intense light blinded Siyeon inside. She shielded her eyes and sobbed, but his fingers were already slinking toward her dress hem—and the grimy keyboard.
"Alright, series title: 'Housewife Trapped in a Smartphone'. Episode 1: 'Chastity's Flower, Wet from a Stranger's Touch'. Like it, Siyeon? Your body will react to every letter I type from now on❤️"
"Nooo... stop... please... you psycho!"
Siyeon's desperate screams seeped through the goshiwon's thin walls, but the only listener was her tormentor. She wailed her husband's name, but it drowned in Jin-seok's heavy breathing and the clacking keys.
Jin-seok checked her Character Sheet again. Mental strength had dipped slightly. Pleasure-pain system messages glowed faintly.
Target's chastity ideology beginning to crack faintly.
'Burlap Sack' setting friction and heat increase love juice secretion by 150%.
"Hehe, already soaking like this? Imagine when I turn you into a full bitch—how much sloppier will you get? Can't wait."
"Schlurp... squelch❤️"
"Nnghaaa... your filthy hands...!!❤️"
"lololol so cute, adorable... Yeah, gotta change you slow for max fun. Won't be long before you're a drooling mess anyway, so enjoy it lol."
Jin-seok's finger slowly traced Siyeon's crotch on the screen. She curled up at the eerie sensation, goosebumps rising—but her body was already eroding, slow and sure, under its master's delusions. Hell hadn't even turned the first page.
