JEON JUNGKOOK
Apparent Age (Human Form): 25
Real Age (Demon): Over 300 years old
He was turned into a demon centuries ago after making a tragic deal. Though time changed him, he's forever frozen in his prime-young, powerful, and tormented.
Choi Y/N
Age: 22 yrs old
A university graduate or student, living alone, emotionally intuitive, and unknowingly tied to Jungkook by fate-perhaps even a reincarnation of the soul he once died for.
AUTHOR'S POV
Y/N had always felt like someone was watching her-but never in a creepy way. It was something darker. Something warm, but shadowed. As if the air around her knew secrets she wasn't meant to learn.
She lived alone in a quiet, old town tucked between foggy hills. Her life was simple-morning coffees, late-night books, the soft hum of silence that never really stayed silent.
One night, under the light of a full moon, she woke up feeling... touched. A soft graze across her cheek. The brush of warm breath at her ear. But when she opened her eyes, no one was there.
Her heart raced.
And then she heard it.
A whisper.
"You're mine."
---------
Jungkook had roamed the night for centuries-feeding on darkness, sin, and desire. But Y/N... she was different. He wasn't drawn to her soul like others.
He was drawn to her body. The way her chest gently rose and fell as she slept. The softness of her lips. The shape of her neck. The scent of her skin-like a memory he never had.
Every night, he came through the shadows. His form was half-real, cloaked in darkness and heat. He watched her. Sometimes, he couldn't help himself. He kissed her forehead. Brushed his lips down to the corner of her mouth.
Wrapped his arms around her sleeping body and pressed her back against his chest.
She never woke up. But she always sighed softly in her sleep.
And every night, he whispered, "Soon."
--------------
One night, Y/N woke up in the middle of his touch.
She didn't scream. She didn't move.
Because he was beautiful. Tall. Shadows clung to his sculpted chest like clothing. His eyes glowed like dying embers-dark and hungry. And yet, there was softness in them.
"Who... are you?" she breathed.
He tilted his head, amused, yet serious.
"I am the one who's been loving your body every night."
She should have been terrified. But her heart didn't race from fear-it raced from something else. Something forbidden. Something she didn't understand but wanted to feel again.
"Why me?" she asked.
"Because you feel like fire in a world of cold," he whispered, pressing his lips to hers.
And for the first time, she kissed him back.
---------
Y/N should've pushed him away.
She should've run, screamed, prayed-but instead, her fingers curled into his chest, and her lips stayed against his.
His kiss was deep, hungry, as though he'd been starving for centuries-and maybe he had. His hands roamed her back slowly, possessively, pulling her closer. Her body responded like it had always belonged to him.
When they finally broke apart, his breath was ragged.
"You don't understand what you've done," he whispered against her lips, eyes darkening like an eclipse.
Y/N looked up at him, chest heaving. "Then tell me."
He stepped back, barely able to keep his eyes off her.
"I'm a demon, Y/N. Not a myth. Not a story," he said. "I was cursed to wander this world... forbidden to touch the living. But when I saw you, I couldn't help it."
"Why me?" she asked again, voice softer.
His gaze dropped to her lips.
"Because your body calls to mine. Your warmth wakes something in me that I thought was dead."
She shivered as he leaned in again.
"I come to you every night because your skin remembers me. Even if your mind forgets by morning."
-------
Jungkook hovered above her, his breath fanning across her lips. His body was tense-like he was holding back an ocean inside him. His fingers brushed her jaw, then trailed down her throat, where her pulse beat wildly beneath soft skin.
"You want me," he said, voice dark velvet. "But you don't know what I am when I give in."
Y/N reached up, fingers grazing the ridges of his inhumanly strong arms. She didn't speak. Her eyes said everything.
She trusted him.
And that scared him more than anything.
He leaned down, pressing a slow, burning kiss to the hollow of her throat. Her breath hitched. His lips stayed there a moment longer than necessary-drinking in the heat of her skin like it could cleanse him.
"You smell like temptation," he whispered, voice rough. "Every part of you begs me to lose control."
"But you won't," she whispered back.
His eyes flashed. "Don't test me."
He kissed her again-soft but lingering-his hands buried in the sheets beside her, clenching so tightly his knuckles cracked.
When he pulled away, she whimpered from the loss.
"Not yet," he said, eyes wild with restraint. "I want to earn it. Your trust. Your body. Your soul."
Y/N blinked, stunned. "You already have it."
"No," he said, brushing her hair behind her ear with such tenderness it ached. "Not fully. You still don't know what I've done. What I am."
He pulled back, standing at the edge of her bed, his figure cloaked in shadow. "I'll keep coming to you... but I won't touch you like that. Not until you ask again. With your heart. Not just your desire."
And then, like smoke, he vanished into the dark.
----------
Y/N couldn't sleep anymore.
Not peacefully, at least.
Every night since Jungkook's touch, her dreams had turned into flames. She would wake up breathless, tangled in sweat-damp sheets, her body aching for something-someone-who wasn't there.
She missed him. Even his absence was intimate now.
During the day, she would zone out in the middle of conversations, her mind drifting back to his voice, his lips, the way his hands trembled with restraint. She found herself whispering his name into the silence of her room, hoping he'd come.
And one night, he did-but not the same.
He didn't crawl into her bed.
He didn't touch her.
He stood by the window, bare chest gleaming under the moonlight, his eyes glowing dimly like dying stars.
"You're suffering," she said softly.
He looked at her, jaw tight. "So are you."
"Why don't you come to me?"
"Because the more I touch you, the more I remember who I used to be."
Y/N stood, wrapping a blanket around herself as she walked toward him. "Tell me."
His silence stretched like a thread about to snap. Then finally, his voice broke the stillness.
"I wasn't always a demon. I was once human. Like you."
Her eyes widened.
"I was a warrior. A protector. But love... it cursed me."
He turned to face her fully. "I loved a woman. Deeply. Obsessively. And when she died, I made a deal with the underworld to bring her back. I paid with my soul. But they tricked me. They gave me power... and took everything else."
Y/N reached out, her hand ghosting over his. "Do you still love her?"
"No," he said without hesitation, staring at her like she was the only light he'd ever seen. "Because she never made me feel the way you do."
Her heart thudded.
He stepped closer, breathing her in like she was the only thing keeping him tethered to this world.
"But if I fall for you," he whispered, "I'll lose control. And if I take you fully... there's a chance you'll never wake up the same."
Y/N didn't flinch. She raised her hand, resting it gently against his chest.
"Then show me who you really are," she said. "Let me decide."
------
The room trembled with silence.
Y/N's hand was still pressed against Jungkook's chest. His heart-or whatever dark thing beat beneath his skin-thumped under her palm like thunder waiting to be unleashed.
"You want to see who I really am?" he asked, voice low and dangerous.
She nodded, not trusting her voice. Her breath caught when his fingers grazed hers and pulled them away from his chest.
"Don't say I didn't warn you."
And then... he let go.
Not of her-but of himself.
In an instant, the room dimmed. The air thickened, charged with power. Shadows spilled from his body like living ink. His skin darkened, glowing faintly with cursed runes. His back arched-and wings, massive and veined like smoke and fire, burst from him, curling and spreading wide.
His eyes turned pitch black with flickers of red, no longer human.
He looked like sin incarnate.
And yet... Y/N wasn't afraid.
She should've been.
But all she saw was pain, power, beauty-and the same man who kissed her like she was fragile and touched her like she was holy.
Jungkook knelt before her, his wings folding behind him. His head bowed, his voice rough with vulnerability.
"This is me. Not the man in your dreams. Not the illusion you kissed. This is what I am... a demon made of shadows and desire. Tell me to leave, and I will."
Y/N dropped the blanket. She knelt before him slowly, her hands trembling as she reached up and cupped his face.
"You think this will scare me?" she whispered. "You forgot... you've already touched my soul."
His jaw clenched, fangs barely visible now. "I could destroy you, Y/N. With one kiss. One night."
"Then take your time," she whispered, leaning in. "Burn me slow."
Jungkook growled, a deep sound from his chest, and surged forward-kissing her not like a man, not like a monster, but like someone who had waited for her across lifetimes.
Her fingers slid up into his hair, his claws grazing her bare arms without hurting her.
And then-
He pulled away with a gasp, eyes wild.
"If we keep going... I won't stop tonight."
Y/N met his gaze. "Then don't."
But Jungkook stood, wings curling tight around him like a cloak. "Not yet. Not until you truly understand what it means to love a demon."
Then he vanished into black mist, leaving her on the floor-burning, shaking, craving him more than ever.
Y/N was unraveling.
She could feel him even when he wasn't there.
His presence lingered in the curve of her neck, in the warmth of her sheets, in the echo of her name whispered against the back of her mind.
Days started feeling like dreams.
And nights? Nights were fire.
He hadn't come to her bed since showing his true form. But that didn't stop the ache. If anything, it made it worse. Now, every shadow made her pulse race. Every time the air shifted, she hoped he was near.
She started dreaming in ways that felt too vivid to be dreams-hands wrapping around her waist, lips ghosting along her collarbone, a deep voice growling mine into the hollow of her throat.
And in the mirror, sometimes-just sometimes-she'd see a flicker of red behind her.
He was haunting her.
And she didn't want it to stop.
---
One afternoon, while she stood at the sink, washing a cup, her knees suddenly buckled. A wave of heat crashed over her, a phantom touch skimming her lower back.
Her breath hitched. "Jungkook..."
No one was there.
But her reflection in the window was trembling.
"You feel me," his voice murmured from nowhere. "Even when I don't touch you."
"Why are you doing this?" she whispered, heart hammering.
"Because you said 'don't stop.'" His voice curled around her like smoke. "So I'm giving you what you asked for."
She gripped the counter, jaw clenched. "Then stop teasing me and come to me."
"You're not ready. Not until you say it with your whole being."
She closed her eyes. "Say what?"
A pause.
"Say that you love me. Not the man. Not the body. Me."
---
That night, she didn't sleep.
She summoned him.
She slipped under the covers, heart racing, lips parted-and whispered into the dark:
"I love you, Jungkook. Demon, wings, fire... all of you."
The air cracked.
And then he was there.
On top of her. Around her. Inside her energy.
His body didn't just press against her-it claimed her. His wings curled around the bed like a cocoon. His lips hovered over hers.
"You called me," he breathed.
"And I'm not letting you go," she whispered back.
Their lips met again-slower, deeper, burning with everything left unsaid. His hands roamed her body like he was memorizing every inch. His hunger was restrained-but barely.
His voice broke against her mouth. "If we go further... your soul will bind to mine. Forever."
Y/N looked into his eyes-both terrifying and tender.
"Then make me yours."
-------
Jungkook's lips pressed urgently against yours, his hands gripping your waist with an intensity that bordered on desperation. He kissed you like a man starved, pouring centuries of loneliness into the embrace. His tongue traced the seam of your lips, seeking entrance, desperate to taste more of your warmth.
He broke the kiss suddenly, his eyes glowing an eerie red as he looked at you with an intense hunger. A smirk played on his lips - dangerous and beautiful. "Shh, you're too addictive... I might actually break my own curse and fall for a human."
His smirk deepened as if he'd made a decision. He picked you up suddenly, making you yelp. Your legs automatically wrapped around his waist. He pressed you against the wall, kissing you deeply again. His control was paper-thin - like he wanted to devour you whole.
He nipped at your bottom lip, soothing the sting with his tongue. His hands roamed your body possessively, as if trying to memorize every curve. He buried his face in your neck, inhaling deeply. "You smell like heaven... and I'm the demon who's been cast out."
AHHHH......JUNGKOOK,
His forked tongue snaked out, licking a trail from your collarbone down to your stomach, making you shiver. He looked up at you with glowing red eyes, his demonic nature taking over. "Delicious..." He growled, his voice rumbling like distant thunder.
Without warning, he ripped your shirt open, buttons flying everywhere. He latched onto your breast, his demonic tongue swirling around your hardening peak. His hands gripped your hips tightly as he feasted on you like a starving man.
Ummmm....Ahhhhhh,He sucked harder, his sharp fangs grazing your skin. He lifted you up higher, giving him better access. He switched to the other breast, giving it the same treatment. His tail wrapped around your leg possessively. "So sweet..." He murmured against your skin, his voice muffled.
AHHHHH JUNGKOOK,
He groaned deeply at the sound of his name on your lips, sending a shudder through his body. He moved lower, his demonic tongue tracing a path down your stomach. He looked up at you with those intense red eyes, full of hunger and something more primal.
Without warning, he gripped your legs and spread them wide, exposing you to him completely. His demonic tongue flicked out, licking your sensitive folds. You moaned loudly, gripping his horns for support. He growled possessively, "This is mine now. No other man will ever touch this."
Yn started crying in pleasure, His tongue plunged deep inside you, making you cry out. He growled again, his tail wrapping around your thigh to keep you spread wide open. He snacked on you like a feast - his demonic tongue doing wicked things that no human man could replicate.
He chuckled darkly against your core, the vibrations sending waves of pleasure through you. "You have no idea how deep a demon can go..." He murmured, proving his point by pushing his tongue impossibly deeper, stroking a spot that made your vision white out.
He pulled back slightly, his lips glistening with your essence. A wicked grin spread across his face as he watched you tremble. "Mmm, you taste even better than I imagined. Centuries of loneliness, and finally..." He licked his lips. "A feast fit for a demon king."
He buried his face between your thighs again, his tail wrapping around your other thigh to keep you trapped and exposed. He started to purr, the vibrations resonating through you as he licked and lapped hungrily. He was losing control, his demonic nature taking over completely.
Without warning, he shifted his form slightly, his demonic nature elongating his tongue even further. He pushed his tongue inside you with a snarl, reaching a depth no human man could ever dream of. You screamed his name, your hands clawing at the sheets. "This is just the beginning..."
He pulled back slightly, his breath ragged and his eyes burning with an intense, primal hunger. He licked his lips once more, savoring your taste. "I can't get enough of you," he growled, his voice deeper and more demonic than before.
Ahhhhhh,He watched you arch and moan. His demonic nature loved your reactions. His tail rubbed your leg possessively. He plunged his tongue deep again, twisting slightly to hit that sweet spot. He growled, "You're like a drug. The more I taste, the more I need..."
I'm cumin ,He growled in approval, feeling your body tense and release around his tongue. "That's it, come for me," he murmured, not slowing down his relentless assault. He sucked gently on your sensitive nub, drawing out your orgasm as long as possible.
As your orgasm subsided, he slowly withdrew his tongue, licking his lips with a smug smirk. His glowing red eyes watched your trembling form with intense satisfaction. "Magnificent..." He breathed, voice husky. "No mortal woman has ever tasted this divine."
He slowly unzipped his pants, freeing his massive, throbbing erection. It was larger and more intimidating than any human man's, with thick veins pulsing along its length. He gripped your hips and positioned himself at your entrance, his hot breath fanning over your ear.
Will it fit I asked, He chuckled darkly, his tail wrapping around your thigh to pull your leg up higher. "It will fit. I'm a demon, after all. We're built differently." He nuzzled his face against yours, his hot breath carrying a hint of sulfur.
Ahhhh,He pushed forward slowly, his massive size stretching you to your limits. You gasped and whimpered, your nails digging into his arms as he inched deeper. He hissed through his teeth, "So tight... like a virgin." He pulled back slightly before thrusting forward again. "Fuck..."
He groaned deeply as he sunk into you fully, his monstrous size filling you completely. He paused, allowing your body to adjust. "Holy hell..." He panted, his demonic eyes rolling back slightly from the intense pleasure. "I'm going to ruin you for human men."
He began to move, his powerful thrusts shaking the bed. Each thrust hit you deeper than you thought possible, his demonic size stretching you open. "Your little human pussy can't handle a demon, can it?" He grunted, his tail wrapping around your waist to keep you pinned.
Ahhhhhhhhhh, Jungkook she started crying in pleasure, He watched your breasts bounce with each powerful thrust. His demonic nature loved your soft, human body. He spread your legs wider with his tail, going even deeper. He hit a spot that made you scream, his lips curved wickedly. "Found it..." He muttered, targeting that spot relentlessly.
His tail smacked your thigh possessively as he pounded into your sweet spot. He growled, "Take this demon dick. How many human men can hit this spot?" He withdrew slightly before thrusting back in hard, making your breasts bounce.
NO ONE, He roared with laughter, his tail wrapping around your throat gently. "Of course not. You're too small for human men. Only a demon like me can fill you up properly." He thrust deeper, hitting that spot over and over, making you see stars.
*He growled softly, his tail rubbing your leg lovingly. He knew he was hitting your deepest spot. "You're like a baby doll. Too tiny for real sex.
He chuckled darkly at your moan, his monstrous thrusts never easing up. The bed creaked dangerously under the intensity of his demonic passion. "Human men are toys compared to a demon like a demon like me pulls himself deeper into him,."
He smirked wickedly, reveling in your desperate affirmations. His massive demon cock throbbed intensely inside you, stretching your tiny human hole to its absolute limit. "That's right, take it like the delicate little doll you are," he growled, his thrusts becoming even more brutal.
His voice dropped to a low, gravelly growl as he began to speak filthy words into your ear. "You know what this is? This is what you get when you fuck a demon. A real cock, not some tiny little thing human men have." He thrust harder, emphasizing his point.
His tail tightened around your throat possessively as he began to speak even more dirty words. "You're just a little human pussy, getting destroyed by a massive demon dick. Human men would cry if they saw this. Your tiny hole is being ruined."
He threw his head back with a demonic laugh, his hips snapping forward even faster. "Is it? Your little human body is surprisingly accommodating for a demon's size.
I don't want anyone but you,
His eyes flashed with demonic possessiveness at your words. He pulled out almost completely before slamming back in, making you gasp. "Good girl. You're already addicted to demon dick, aren't you? No human can compare now."
His massive demon form began to tremble with pleasure and possessiveness as he listened to your words. "Only me? You want only my huge demon dick inside this tiny little human pussy for the rest of your life?" He thrust even harder, his size overwhelming you. "Answer me, doll."
Yes only your dick can satisfy me,His tail wrapped possessively around your waist as he growled softly. His demonic mind loved your answer. He thrust deeper, making you moan. "You'd reject human men if they tried to touch you? You'd only want this demon size?" He grunted, his hips moving like a jackhammer.
I won't let any other men to even look at me,He chuckled deeply, the sound rumbling through his chest as he pinned you beneath him, thrusting furiously. "That's what I like to hear. No other man deserves to even look at this sexy body that now belongs to a demon."
His massive demon form began to glow with a dark energy as he felt your complete surrender. He grabbed your tiny wrists in one of his massive hands, pinning them above your head as he pounded into you mercilessly. "And if a human tries to fuck you, what will happen?"
You will kill them, A wicked grin spread across Jeon Jungkook's demonic face at your possessive declaration. He thrust especially hard, making you scream in pleasure. "Correct answer. Any human man who dares to lay a finger on you will face the wrath of a demon. Your body is mine alone now."
His demonic eyes darkened with possession. He spread your legs wider apart and pounded into you like an animal. "No other man's touch. No other man's kiss. No other man's dick. Only demon dick from now on?"
Yes only your dick, He laughed darkly as he felt your tiny body convulse with an intense human orgasm. His massive demon form kept thrusting, prolonging your pleasure. "Good girl. Scream my name as you cum on my huge demon dick. Who's filling up this tiny human pussy right now?"
YOU THE DEMON KING JEON JUNGKOOK YN CRIED LOUDLY,
He roared triumphantly as your climax peaked, his eyes blazing with demonic satisfaction. "Damn right, human doll. Only a demon can fuck you this good, make you cum this hard on a cock size too big for humans." His thrusts slowed, but remained deep and possessive.
Every night, as the moon rose high in the sky, the demon would appear in your bedroom, his massive form materializing out of thin air. Without a word, he would spread your legs and bury his huge demon dick inside you, fucking you mercilessly until dawn.
AUTHOR'S POV
As nights turned to months, Jungkook stopped hiding.
No longer just a shadow in her bed, he became a constant presence-touching her, loving her, worshipping her in every way his cursed soul knew how. Each kiss grew deeper. Each embrace became a silent promise. And slowly, their bond became unbreakable.
Y/N, once an ordinary girl of 22, gave herself to the demon with fire in his eyes and sorrow in his heart. She welcomed his darkness, his heat, his hunger-until her very soul responded to him.
One night, as moonlight bathed their entwined bodies, he whispered against her skin, "You're more than mine now."
And she was.
Her body changed-her senses sharpened, her heart slowed, her aura turned electric. No longer fully human, Y/N was reborn... not by death, but by love. A transformation forged through soul-binding, longing, and every touch they shared.
Now immortal beside him, she walked through shadows not as prey, but as queen.
The demon and the girl who once feared him now ruled the night together-two souls entwined in flame and desire, forever craving, forever loving.
In the world of darkness, they found their forever.
