Jeon Jungkook || FWB

The clock on the kitchen wall read 2:47 AM.

{User} stumbled through the front door of her parents' house, the faint thrum of bass still vibrating in her chest from the club. Her dress—a sinful little thing in black satin—hugged every curve, the neckline plunging dangerously low and the hem barely grazing her upper thighs. Her heels dangled from her fingers as she padded barefoot through the dimly lit foyer, a giddy smile playing on her lips as she scrolled through her phone.

Her parents were out of the city for the weekend, which meant she had the house to herself—or so she thought.

She pushed open the kitchen door, the cool marble floor sending a shiver up her bare legs. Humming softly, she reached for a glass from the cabinet, filling it with water from the pitcher. Her thumb swiped across her screen, reading the latest string of messages from James. The smile on her face widened, a soft, breathy laugh escaping her lips as she typed back a quick reply.

"You're so bad... maybe I liked it."

She brought the glass to her lips, taking a sip—

And promptly choked.

The water sprayed from her mouth as she coughed violently, her eyes going wide. There, lounging on the leather couch in the corner of the kitchen like he owned the place, sat Jeon Jeongguk. His arms were crossed over his chest, his jaw tight, and his dark eyes fixed on her with an unreadable intensity.

"Uh... you're here?" she managed, her voice cracking as she wiped her chin with the back of her hand.

He rose from the couch slowly, deliberately. Each step he took toward her felt weighted, his presence filling the space until the kitchen seemed too small.

"Why were you not here?" His voice was low, deceptively calm. But she knew him better than anyone. That calm was a storm waiting to break.

She swallowed hard, her pulse quickening. "I went to the club. With some friends."

He was in front of her now, close enough that she could smell the familiar scent of his cologne. His hand shot out, quick as a snake, and snatched the phone from her grasp before she could react.

"Hey—!"

He held it up, his eyes scanning the screen. The messages from James glowed back at him.

James: "Wish you were still here. I'd have you bent over the bar."

James: "That dress made me wanna tear it off you."

James: "Send me a pic when you get home. Want to see what I'm missing."

Her reply: "You're so bad... maybe I liked it."

His jaw clenched, the muscle in his cheek twitching. His knuckles whitened around the phone.

"What the fuck is this?" His voice came out as a dangerous whisper.

"Jeongguk, give me back my phone—" She reached for it, but he pulled it away, his eyes never leaving the screen.

"James?" He let out a humorless laugh, finally lowering the phone to meet her gaze. "Who the fuck is James?"

"No one. Just some guy I met tonight." She tried to sound nonchalant, but her voice wavered. "It's not a big deal."

"Not a big deal?" He threw the phone across the room, where it bounced off the couch and landed on the floor with a soft thud. "He's talking about bending you over a bar, and it's not a big deal?"

"You don't get to do that!" She shoved at his chest, but he didn't budge. "You don't get to act jealous! We're not together—"

Before she could finish, his hands were on her. He hoisted her up effortlessly, her legs instinctively wrapping around his waist as he pinned her against the cool wall. The impact knocked the breath from her lungs, and she gasped, her fingers gripping his shoulders for balance.

His face was inches from hers, his breath hot against her lips. "Not together?" he repeated, his voice rough. "Then explain why I'm the only one who's ever had you like this."

Her cheeks flushed, a mix of anger and something else pooling in her belly. "That doesn't mean anything."

"Bullshit." His lips brushed against her jaw, trailing down to her neck. "I've been inside you more times than I can count. Felt you come undone beneath me. Heard you scream my name." He pressed a kiss to the sensitive spot below her ear. "And you're telling me that means nothing?"

She bit her lip, trying to suppress the shiver that ran through her. "It's just sex. We agreed—"

He pulled back, his eyes dark and intense. "I don't give a shit what we agreed." His hand slid up her thigh, pushing the hem of her dress higher. "You came home dressed like this, smiling at another man's texts, and you expect me to just let it go?"

"You have no right—" Her protest died in her throat as his fingers found the damp heat between her legs, pressing against the thin fabric of her panties.

"No right?" He chuckled darkly, his thumb circling her clit through the soaked material. "I have every right. You're mine. You've always been mine."

Her breath hitched, her body betraying her as she arched into his touch. "Jeongguk..."

"Say it," he demanded, his voice a low growl. "Tell me you're mine."

She shook her head, her nails digging into his shoulders. "I won't—"

He pulled her panties to the side, slipping one finger inside her without warning. She cried out, her head falling back against the wall as he pumped in and out slowly, deliberately.

"Say it," he repeated, adding a second finger. "Or I'll make sure you can't walk tomorrow."

Her walls clenched around his fingers, her breathing ragged. "I'm..." She swallowed, her pride warring with the ache building inside her. "I'm yours."

A satisfied smirk curved his lips. "That's my girl."

He withdrew his fingers and unzipped his jeans, freeing his hardened length. He lined himself up at her entrance, the tip teasing her wet folds before he slammed into her in one swift thrust.

She screamed his name, her back arching off the wall as he filled her completely. The stretch burned in the most delicious way, and she clawed at his back, desperate for more.

He didn't give her time to adjust. He set a brutal pace, each thrust hitting deeper than the last. The wall rattled behind her, the sound of skin slapping against skin echoing through the empty kitchen.

"Look at me," he demanded, his hand gripping her chin and forcing her gaze to his. "I want you to remember who makes you feel like this."

Her eyes were glazed with pleasure, her mouth open in a silent scream as he hit that spot inside her that made stars burst behind her eyes.

"J-Jeongguk—"

"Yes," he growled, his pace quickening. "Say my name. Let everyone know who you belong to."

She could feel the pressure building, coiling tight in her belly. Her nails raked down his back, leaving angry red lines in their wake.

"I'm close," she whimpered.

"Come for me," he commanded, his voice ragged. "Come on my cock, baby."

That was all it took. She shattered around him, her walls clenching and pulsing as waves of pleasure crashed through her. He followed moments later, spilling into her with a guttural groan, his forehead pressing against hers as they both rode out the aftershocks.

He stayed buried inside her, their heavy breathing the only sound in the room. Slowly, he pulled out, and she whimpered at the loss.

He set her down gently, her legs trembling beneath her. She leaned against the wall for support, her chest heaving.

"That wasn't fair," she finally whispered.

He tucked himself back into his jeans and stepped closer, tilting her chin up to meet his eyes. "Life isn't fair." He pressed a soft kiss to her lips, a stark contrast to the roughness moments before. "Now tell me about James."

"There's nothing to tell," she muttered, avoiding his gaze. "He's just some guy."

"Good." His thumb brushed across her bottom lip. "Because if I ever see him near you again, I'll break his hands."

She rolled her eyes, but a small smile tugged at her lips. "Possessive much?"

"Only when it comes to you." He grabbed her hand and led her toward the stairs. "Now come on. I'm not done with you yet."

Jeon Jungkook—son of one of Korea's most prominent businessmen. From the moment of his birth, he had everything. Every toy imaginable, maids attending to his every need around the clock, and parents who showered him with love. It was a picture-perfect childhood, until Jungkook began to feel a gnawing loneliness. There were no other children around, as his parents had agreed to have only him.

His parents had very close family friends—the Kim family. Mr. Kim was as close to Jungkook's father as Mrs. Kim was to his mother. Everything was harmonious, until the Kims announced their pregnancy.

Soon, Jungkook found himself with someone younger—Kim {user}. From her very first breath, Jungkook was drawn to her. He would visit the Kim household just to play with her, and the two grew up side by side.

Their families were overjoyed that their heirs were so close. Whenever someone teased {user} at school, Jungkook protected her as if she were his own sister. But that "sister" label would eventually become irrelevant to the future of their relationship.

The first kiss they ever shared was an innocent, childish act—on Christmas, when Jungkook was seven and {user} was barely four. Their families captured the moment on video, a sweet childhood memory they'd revisit for years to come.

They went through school together, stayed inseparable. They were like each other's shadows. {User} protected Jungkook when he got into fights with fifth graders, and Jungkook shielded her from harmless insects. It was always a fifty-fifty give-and-take—until the year {user} turned sixteen.

From then on, whenever a guy asked her out, Jungkook would confront him, fists clenched. He followed her around like a lost puppy, never straying too far. She had been his everything from the moment she first opened her eyes in this world.

Everything changed one night when, at eighteen, {user} snuck out with Jungkook to a club. It was her first time drinking. She refused at first, but Jungkook assured her no one would suspect a thing. She broke the rule—underage drinking. But what happened after that night altered the course of their relationship forever. They became physical.

The next morning, she cried in his arms, overwhelmed and afraid. But he soothed her, whispering promises that he would never leave her. That was, until he supposedly found a girlfriend—though in reality, Jungkook had no intention of dating anyone else anytime soon.

It became their little secret, hidden from both families. Soon, she came of age, and their encounters grew more intense. Almost every other night, she found herself beneath him, her nails raking down his back as she whimpered his name. They both grew accustomed to this arrangement, and their families remained blissfully unaware.

They always dismissed what they had, roasting each other with the claim that the sex meant nothing to either of them. And for a while, they believed it—until someone asked one of them out.

Will they ever confess the feelings they've buried so deep? Or will they continue to deny the truth until one of them can no longer hold it in?
