Chapter 1: The Devil's Return
The Seoul night pressed against the glass walls of the briefing room, a glittering tapestry of neon and steel that made the city look like a circuit board humming with secrets. Inside, the air was thick with the scent of burned coffee and something else—anticipation, maybe, or the particular tension that gathers when two people who despise each other are about to be forced into the same room.
Jin Yi-soo had been here for twenty minutes already.
He'd made himself comfortable, which was, he supposed, the entire point. The chair was ergonomic and expensive, the kind that adjusted in twelve different directions, and he'd adjusted all twelve until he'd found the perfect recline. His loafers—hand-stitched Italian leather, dark brown, worth more than most people's monthly rent—were propped on the desk with the casual arrogance of a man who had never once in his life been told no.
The desk itself was immaculate. A single monitor, a pen holder with exactly three black pens arranged at precise angles, a stack of case files so neat they looked like they'd been measured. He'd straightened one of them when he'd first sat down, just to watch the perfect lines break. Then he'd straightened it back, because even he had limits.
His phone buzzed. A message from Min-ji, or maybe it was Soo-ah. He'd forgotten which one he'd given his number to last night, and the thought didn't bother him as much as it probably should have.
He was thirty-four years old, wealthy beyond measure, and bored beyond reason. The police academy had been a lark, a way to annoy his father and avoid the family business. The detective work had been a joke, a series of cases he'd solved through connections and charm rather than actual effort. And now here he was, three years in, with a reputation as the laziest detective in the Seoul Metropolitan Police Agency, and he'd just been informed that his new team leader was someone he knew very, very well.
The door hissed open.
Joo Hye-ra walked in like she owned the building, which was funny, because she owned nothing. She'd grown up in a one-room apartment in Gangseo-gu, raised by a mother who worked two jobs and a father who'd disappeared before she could walk. Everything she had, she'd clawed for. Everything she was, she'd built with her own two hands.
It was, Yi-soo thought, one of the things he respected most about her.
It was also, he was certain, one of the things she hated most about him.
She was dressed in the same dark suit she always wore, the one that fit her lean, athletic frame like a second skin. Her hair was pulled back in a ponytail so tight it looked painful, and her eyes—those piercing, furious eyes—were fixed on him with the kind of intensity that made lesser men flinch.
Yi-soo didn't flinch. He smiled.
"Well, well," he drawled, letting his voice carry across the room like smoke. "If it isn't my favorite nightmare."
Her jaw tightened. She didn't dignify that with a response. Instead, she walked to the desk—his desk, technically, though she didn't seem to care—and placed a manila folder onto the pristine surface. It landed with a soft thump that somehow felt like a gunshot.
"You're in my chair," she said.
"I'm aware." He made a show of adjusting his position, crossing his ankles more comfortably. "It's a very good chair. You have excellent taste."
"I don't have taste." Her voice was flat, colorless. "I have a budget." She reached past him to tap the monitor, and he caught a whiff of something clean and sharp—soap, maybe, or that particular scent of determination that seemed to cling to her like perfume. "The budget also includes you being upright and alert, Detective. Not lounging like you're on a beach in Bali."
"Bali is beautiful this time of year." He didn't move. "You should go. Clear your head. You look tense."
Something flickered in her eyes. It was there and gone so fast he almost missed it, but he didn't. He was good at reading people, even when they didn't want to be read. Especially when they didn't want to be read.
"I look tense," she repeated, her voice dropping low, "because I just spent forty minutes in a meeting with the Commissioner, convincing him that I could work with you without throwing you out a window." She leaned forward, placing both hands on the desk. Her face was inches from his, and he could see the faint lines of exhaustion at the corners of her eyes. "Do you know how much I had to promise to make that happen?"
"I assume your firstborn child and a signed confession to a crime you didn't commit."
"Close." She straightened, and for a moment—just a moment—she looked almost tired. Then the mask slid back into place, hard and impenetrable. "I told him I'd handle you. That I'd make you into a real detective or die trying."
"Those seem like the only two options with you."
"They are." She reached for the folder, flipped it open with a flick of her wrist. A photograph slid out onto the desk. "And right now, you're going to help me with a case."
Yi-soo didn't look at the photo. He was too busy watching her face, searching for the cracks in her composure. He'd known her for six years now—six years since she'd stood at the front of a police academy classroom, twenty-eight years old and already terrifying, and made him run laps until he'd vomited into a gutter. She'd been his devil instructor, his tormentor, the only person in his life who had ever made him feel genuinely incompetent.
He'd hated her for it. He'd also, in some twisted way he never acknowledged, respected her for it.
"Let me guess," he said, finally letting his gaze drift down. The photograph showed a man in his forties, handsome in a sharp, angular way. He was standing in front of a canvas, paintbrush in hand, a faint smile playing on his lips. "He's a serial killer with a god complex and a penchant for leaving calling cards?"
Hye-ra's eyebrow twitched. "Close. He's an artist. A successful one. He exhibits in three countries, sells pieces for six figures, and has never once been accused of anything more serious than a parking violation."
"So he's a successful artist with a god complex and a penchant for leaving calling cards."
"You're not wrong." She flipped to another page in the folder. "Three women have gone missing in the last eight months. All of them were involved with the art scene in some way. A gallery assistant. A curator. A patron." She tapped the photo. "All of them were last seen at exhibitions featuring his work."
Yi-soo uncrossed his ankles, letting his feet drop to the floor with a soft thud. He leaned forward, suddenly more interested than he wanted to be. "And you think he's your guy?"
"I don't think." Her voice was ice. "I know. I've been building this case for six months, and I've got nothing that would hold up in court. Nothing that would convince a prosecutor to even look at him." She paused, and something shifted in her expression—a crack in the armor, a flash of something vulnerable. "I need someone who can get close to him. Someone who..." She trailed off, and he watched her struggle with the words. "Someone who can play his game."
The room fell silent. The only sound was the distant hum of the city outside, muffled by the glass like a heartbeat heard through a wall.
Yi-soo leaned back in the chair, a slow grin spreading across his face. "Let me get this straight. You—Joo Hye-ra, my personal devil, the woman who made me do push-ups in the rain until I passed out—you're asking me for help?"
"I'm not asking." She slammed the folder shut with a crack that made him blink. "I'm telling you. This artist is a killer, and you're going to help me catch him—or I'll make your life a living hell, just like old times."
He raised an eyebrow. "You can't make my life a living hell. I'm already wealthy, handsome, and immune to your particular brand of torture."
"Really?" She smiled, and it was the coldest thing he'd ever seen. "Then you won't mind me telling Commissioner Park about that little incident at the Blue House party last year. The one involving the diplomat's wife and the unlocked supply closet?"
Yi-soo's smile faltered. Just slightly. Just enough for her to notice.
"You wouldn't," he said.
"Try me." She crossed her arms, and for the first time since she'd walked in, she looked almost relaxed. Almost satisfied. "I've got six months of evidence that Yoo Seong-won is a killer. I've got nothing that could convict him, but I've got more than enough to make him nervous. And I've got you—the only person I know who can charm his way into any room, any bed, any secret." She paused, letting the words hang in the air between them. "You're going to get close to him. You're going to find his weakness. And then we're going to take him down together."
Yi-soo stared at her for a long moment. The city hummed outside, indifferent. The stale coffee smell lingered in the air, a testament to all the sleepless nights that had come before this one.
Then he laughed.
It was a sharp, surprised sound, ripped from somewhere deep in his chest. He couldn't help it. The absurdity of the situation was too much—her standing there in her cheap suit with her expensive fury, demanding that he become something he'd never bothered to be.
"You're serious," he said, the laughter still catching in his throat. "You're actually serious."
"Deadly." She didn't smile. "And I'm not asking permission. I'm giving you a choice. Help me, and I'll make sure you walk away from this looking like a hero. Refuse, and I'll bury you so deep in paperwork that your grandchildren will be filing reports."
He considered her for a moment. Then he looked down at the folder, at the man's face staring up at him with that faint, knowing smile. Yoo Seong-won. A killer who painted pretty pictures and charmed his way through the upper echelons of Seoul's art world.
It was, Yi-soo thought, almost like looking in a mirror.
"Fine," he said, and the word tasted strange on his tongue. "I'll help you."
Hye-ra's eyes narrowed, suspicion flickering in their depths. "Just like that?"
"Just like that." He stood up, smoothing the creases in his suit jacket. "You're right. I can charm my way into anything. And frankly, I'm bored. If your artist is as dangerous as you say he is, then this might actually be interesting." He smiled at her, a flash of teeth. "Besides, I owe you. You made me throw up in the gutter in front of half my class. This seems like a fair trade."
Her mouth quirked—almost a smile, though she'd probably deny it if he asked. "I'll consider us even when he's in handcuffs."
"Deal." He extended his hand, and after a moment's hesitation, she took it. Her grip was firm, calloused, nothing like the soft, manicured hands of the women he usually spent his time with. It was, he realized, the hand of someone who had fought for everything she had and wasn't about to stop now.
He liked it. He hated that he liked it.
"Get out of my chair," she said, pulling her hand back. "We're briefing the team in an hour. I'll send you the files."
"I look forward to it." He grabbed his phone from the desk, sliding it into his pocket. He was halfway to the door when her voice stopped him.
"Yi-soo."
He turned. She was standing behind the desk now, her hands flat on the surface, her dark eyes fixed on him with an intensity that made something in his chest tighten.
"Don't mess this up," she said quietly. "I don't trust you. I've never trusted you. But I'm putting my career on the line for this, and if you disappoint me—" She paused, and the weight of what she wasn't saying filled the room like smoke. "If you disappoint me, you'll wish you'd never been born."
She watched him carefully, her fingers drumming once on the desk like a metronome ticking down to zero. "I don't care how good you think you are. I don't care about your family name, your connections, or your designer fucking shoes. You screw this up, and I will ruin you."
Yi-soo exhaled slowly, letting the threat wash over him. It wasn’t the first time someone had promised to destroy him, and it wouldn’t be the last. But coming from her, the words carried weight—not because she could back them up, but because he knew, deep in the marrow of his bones, that she *would*.
The thought sent a shiver down his spine, the kind that had nothing to do with fear and everything to do with something far more dangerous.
Anticipation.
He smirked, just to fuck with her. “Noted,” he said smoothly. “But if we’re going down that road, Hye-ra, you should know—ruining me might be harder than you think.”
She didn’t rise to the bait. Instead, she gave him a single, slow nod, her lips pressed into a thin line that could’ve been misinterpreted as approval—or at least grudging respect. It vanished a second later, replaced by the usual frost. “Get out,” she said again, sharper this time.
“Before I change my mind about the whole team briefing.”
Jin Yi-soo smirked, enjoying the way her nostrils flared at the sight of his smugness. He sauntered toward the door, his designer loafers clicking against the polished floor.
“See you at the briefing, *devil*.” The nickname rolled off his tongue like a curse—or maybe a prayer—and it earned him a sharp inhale from Hye-ra before he disappeared down the hallway.
The walk back to his office was a blur of phone calls and empty flattery from colleagues who wanted to kiss his ass—or other parts of him.
Yi-soo nodded politely, muttered the right words, and let his mind drift elsewhere. The entire time, though, he could *feel* the weight of her glare burning into his back like a brand.
By the time he reached his own glass-walled office—smaller than hers, less intimidating, more *his*— he was already loosening his tie. Not because he was tired. Not because he was stressed.
Because he was *hard*.
He dropped into his chair, spun it toward the floor-to-ceiling window, and stared out at the city skyline. The lights were too bright, too artificial, too far away.
Yi-soo’s reflection in the glass was just another ghost in the neon haze, indistinguishable from the thousands of other suits floating through Seoul’s corridors of power. But Hye-ra’s office was directly across from his, its glass walls a transparent barrier that made privacy impossible. He could see her through the reflection, could watch the way she moved—efficient, precise, like a blade unsheathed. She was pacing now, phone pressed to her ear, her jaw tight as she listened to whoever was on the other end.
Yi-soo adjusted his tie, just slightly, loosening the knot enough to breathe. Then he reached down. He unbuckled his belt first, the leather whispering against his skin, then the button of his trousers gave way with a soft *pop*. His fingers trailed lower, tracing the outline of his cock through the fabric of his briefs.
He stroked himself—slow, deliberate, watching her through the glass like a voyeur in his own damn building. She still hadn’t noticed him, too caught up in whatever conversation was sapping the color from her face, her free hand gripping the edge of the desk like she was holding onto something fragile.
The sight was… distracting. Intoxicating. Hye-ra had always been a woman who carried herself like she owned the world, even when she was drowning in debt or sleep-deprived. But now? Now she looked like she was one bad call away from snapping, and for some reason that made his pulse spike.
He adjusted himself free from his boxers, his palm wrapping around the thick, heavy weight of his cock, the skin already flushed and sensitive from the teasing. He groaned low under his breath, biting back a curse.
His cock throbbed in his hand, the head already slick with pre-cum, the veins pulsing beneath his touch. He imagined Hye-ra’s face as she listened to whatever bullshit was being fed to her over the phone, her lips pressed into a thin line, her eyes narrowed in frustration. The thought of her being so vulnerable, so *exposed* to whatever was making her blood boil, made his grip tighten.
He was hard as fucking steel, and he didn’t give a damn who saw.
His cock jerked in his hand, the tip already glistening with pre-cum, the veins throbbing with need.
He leaned back in his chair, watching her through the glass as he stroked himself. Her voice was sharp, commanding, but there was an edge to it—something raw and desperate. She was good at hiding it, but he knew her well enough to see the cracks.
The way her fingers tightened around the phone, the way her shoulders tensed like she was bracing for a blow. He could almost hear the words she wasn’t saying—*I’m not weak, I’m not weak, I’m not weak*—but the way her voice cracked, just once, told him the truth. She was exhausted. She was furious. And she was *so* close to snapping.
Yi-soo’s fingers slid wet over his cock, the slick sound of his palm gliding against his shaft making his breath catch. He was hard as fucking steel, the veins throbbing beneath his touch, and he didn’t give a damn who saw. He didn’t give a damn if she heard him, either.
The thought of her watching him—even if she didn’t know it—made his cock twitch in his hand, the tip already slick with pre-cum. He leaned forward, his breath hitching as he imagined her face when she realized what he was doing.
The phone call ended abruptly. Hye-ra hung up, her fingers still trembling around the receiver. She didn’t even notice Yi-soo’s reflection in the glass, her attention locked on the file in front of her. She slammed it shut with a sharp *thud*, her chest rising and falling rapidly.
Yi-soo’s cock pulsed in his hand, the veins throbbing with need.
He could feel his balls tightening, the heavy weight of his erection pressing against his palm. His other hand fisted in his hair, pulling just enough to make his head loll back against the chair. He groaned, the sound raw and needy, his breath coming in sharp, uneven gasps.
He was hard as fucking steel, and he didn’t care if she saw him. Didn’t care if she knew what she was doing to him. The thought of her—so cold, so controlled—being reduced to this, to *this* kind of vulnerability, was almost enough to make him come right then and there.
His cock pulsed in his hand, the veins throbbing with need, and he groaned low, his breath coming in sharp, uneven gasps. He stroked himself harder, his fingers slick with pre-cum, the sound of his palm sliding against his shaft filling the room.
His cum splashed his desk mirror.
The glass fogged instantly, the white streaks of his release smearing across the surface like a secret confession. Yi-soo’s breath hitched, his body tensing as he watched the evidence of his own need spread, the heat of it still visible even through the condensation. He groaned again, his hips jerking forward as his cock pulsed in his hand, the tip throbbing with the pressure of his orgasm building.
He could see it in the way her shoulders were hunched, the way her fingers dug into the edge of her desk like she was trying to anchor herself to something solid. She was *fucking furious*, and he knew exactly how that felt.
His cock jerked in his hand, the head throbbing with need. He leaned forward, his breath hitching as he imagined her face when she finally looked up and realized what he was doing. The thought of her seeing him like this—exposed, desperate—made his balls tighten, the heavy weight of his erection pressing against his palm.
He groaned low, the sound raw and needy, his breath coming in sharp, uneven gasps.
His cock pulsed in his hand, the veins throbbing with need, and he groaned again, his hips jerking forward as his cock swelled even thicker beneath his grip. The tip was already flushed, swollen, leaking pre-cum in thick, glistening drops that slicked his palm.
He rubbed his thumb over the slit, smearing the moisture in slow circles, watching as the head darkened, the vein beneath it pulsing erratically. His breath came in sharp, uneven gasps, his chest heaving—not from exertion, but from the sheer, filthy thrill of knowing she was right across from him, unaware, unknowing, and yet *so close* to witnessing what he was doing to himself.
He shifted in his chair, spreading his thighs wider, letting the fabric of his trousers pool around his knees. His cock jutted up from his lap like a weapon, thick and veined, the skin stretched taut over the shaft, the head weeping.
He wrapped his fist around the base, squeezing just hard enough to make the blood pool deeper, the color darkening to a deep, angry red. A bead of pre-cum welled at the slit and he smeared it over the head of his cock using the pad of his thumb, collecting the slick fluid before dragging it down in slow, teasing strokes that made his hips jerk involuntarily.
“Fuck,” he hissed under his breath, biting down on his lower lip.
He could feel the weight of his balls, heavy and full, drawing up tight against his body. His thighs trembled with the effort of restraint. He didn’t want to come yet—not this fast, not like this.
The glass between them was a mockery, a tease. He wanted her to see him. He wanted her to *know*.
With a growl, he released himself long enough to shove his chair back from the desk. It rolled on silent casters until he could kick the door closed with the heel of his loafer. The lock clicked. The city lights outside pulsed like a heartbeat. He stripped off his jacket, then his tie with a single, practiced tug that sent the silk slithering to the floor. Shirt buttons popped when he yanked it open—two of them pinged off the window so hard they left tiny starbursts in the glass.
The fabric gaped open, exposing the hard planes of his chest and the dark trail of hair that disappeared beneath his belt. He didn’t bother unbuttoning the trousers; he just shoved them and his boxers down in one brutal motion, kicking them off so they pooled around his ankles. His cock sprang free, thick and flushed, the head already weeping, the skin pulled taut over veins that pulsed visibly with every heartbeat. He fisted himself again, the grip bruising, the motion rough and needy.
He heard her gasp.
It was so faint he almost missed it through the glass, but he *felt* it—like a hot brand pressed against his skin.
Yi-soo froze mid-stroke, cock still fisted in his hand, his breath catching in his throat as he turned his head just enough to glance through the reflection.
The reflection showed her exactly as before, head bent over the file, unaware, and the relief of it hit him harder than the fright. She hadn't heard him. The gasp had been his own, bounced back off the glass. He was alone with this, alone with her, and that was somehow filthier.
He turned his chair a fraction, angling himself so he could watch her without craning his neck. His hand resumed its rhythm, slower now, savoring it. His cock was a slab of wet heat in his fist, the foreskin bunched under the swollen head, pre-cum dripping in a thin thread onto his bare stomach.
Through the glass, Hye-ra pulled her ponytail loose.
He almost came right there.
Her hair fell around her shoulders, dark and heavy, the first time he'd ever seen it down. She dug her fingers into her scalp and massaged, head tipping back, throat exposed in the harsh office light. Six years of that tight, punishing bun, and now it was just hair, soft and loose, and he wanted to wrap it around his fist and fuck her mouth with it.
"Jesus Christ," he whispered.
His hips lifted off the chair. He fucked into his own hand, short desperate strokes, the chair creaking under him. His balls slapped wet against his thigh with every thrust, drawn up tight, aching. Sweat slid down his open chest and pooled in the hollow of his throat.
On the other side of the glass, she stood. She stretched, arms over her head, and her jacket rode up, showing a strip of bare skin above her waistband. Then she shrugged out of the jacket entirely and draped it over her chair. The white blouse underneath was thin. He could see the shadow of her bra through it, the neat cups, the lean line of her back.
She had no idea. She was proofreading her own doom two meters of glass away from a man jerking his raw cock to the sight of her.
That did it. That was the thought that broke him: her cold, flawless control, her ice and her fury and her cheap suit, all of it oblivious, all of it his, in the filthiest way, and she would never know unless he told her.
His orgasm hit like a punch. His whole body seized, heels digging into the floor, thighs shaking. The first spurt painted his knuckles white, thick and hot, and the second caught him under the chin, a rope of cum striping his jaw and throat. He kept stroking through it, milking himself, gasping, cum pulsing out over his fist and stomach in wave after wave until it dripped down his shaft and gathered in his pubic hair. His knees knocked together. His vision went white at the edges.
"Fuck, fuck, fuck." Each word punched out of him on a ragged breath. His hand was a slick mess, his cock still twitching, oversensitive, the head slick and furious red. He gave it one last slow stroke and shuddered hard enough to rattle the chair.
Through the glass, Hye-ra sat back down. She picked up her phone, dialed, waited, hung up. Utterly normal. Utterly unaware. She gathered her files into a neat stack, checked her watch, and began fixing her hair, gathering it back with practiced fingers into that punishing ponytail.
Yi-soo laughed, low and cracked, cum cooling on his chest.
He cleaned up with a handful of tissues from his desk, wiping his throat, his stomach, his spent cock, which gave a tired, interested twitch at his own touch and then settled. His reflection in the glass was wrecked: flushed, shirt hanging open, hair mussed where his own fist had pulled it. He looked like a man who'd just done something genuinely stupid.
It was the best he'd felt in months.
He was buttoning his trousers when his phone buzzed. A message from Hye-ra, because of course she'd found his number through official channels within an hour.
Briefing moved up. Forty minutes. Conference room B. Don't be late, and don't be drunk.
He typed back with one hand, the other still doing up his belt.
Never late. Never drunk. Occasionally filthy, but you love it.
The reply came in eight seconds.
Meet me in Conference Room B in thirty minutes. We're going over the case files before the team sees them. And delete whatever you just sent me, I don't open links from you.
He hadn't sent a link. He stared at the screen. She'd read the first line and assumed. That was fine. That was better than fine, actually, because it meant she already flinched at his name on her phone, and a woman who flinched was a woman thinking about him.
Yi-soo washed his face in his private bathroom, cold water, hands braced on the sink. The mirror told him nothing he didn't know. He looked like a devil. He combed his hair back, retied a fresh tie, and shrugged into his jacket with the unhurried precision of a man dressing for war.
Thirty minutes later he pushed open the door of Conference Room B, and there she was, exactly as he'd left her: ponytail restored, jacket on, armor sealed. The case files were spread across the table in perfect parallel rows. She didn't look up.
"Sit," she said.
He sat, close enough that his knee brushed hers under the table. She didn't move it away. She didn't look up either, but her pen stopped moving for exactly one second, and he counted that second like a jackpot.
"Yoo Seong-won has an opening on Thursday," she said. "A private preview at his gallery in Cheongdam. Invitation only. Two hundred guests, all money, all champagne, all alibis."
"Let me guess. I'm invited."
"Your name is on the list as of this morning. Don't ask how." She slid a glossy card across the table to him. Heavy stock, gold foil, the man's initials pressed into the corner like a brand. "You get close. You get him talking. You find out what happened to those three women."
"And if he's as smart as you think he is?"
She finally looked at him, and her eyes were sharp enough to draw blood. "Then don't get caught."
"Detective," he said, picking up the invitation and turning it in his fingers, "getting caught is the only part I'm good at."
Something crossed her face, quick and unreadable. She reached across the table and tapped the invitation out of his hand, flat onto the files, and her fingers lingered on it a beat longer than they needed to.
"Thursday," she said. "Try to be useful for once in your gilded life."
He smiled, tasting the ghost of his own secret still on his lips. "For you, devil? I might even try."
She didn't answer him right away. Instead her fingers came back to the invitation, and this time they didn't just tap it. They traced it. Slowly, along the gold foil edge, down the embossed initials, the pad of her index finger following the letter Y like she was reading braille.
Yi-soo watched her do it and forgot how to breathe.
"You've handled this before," he said. "The case. Him. Six months alone with a folder nobody believed."
"I don't need you to psychoanalyze me."
"No." He leaned forward, elbows on the table, close enough to smell the coffee on her breath and the soap underneath it. "You need someone to touch you, and you're terrified it might be me."
Her finger stopped on the card. The room hummed with the ventilation and nothing else.
"That's not what this is," she said, but her voice had lost half its ice.
"Then move your hand."
She didn't move her hand. He covered it with his, his palm flat over her knuckles, pinning her fingers to the gold foil. Her skin was warm. Calloused. She could have pulled away in half a second and they both knew it.
She didn't pull away.
"Yi-soo." His name in her mouth sounded like a warning shot.
"Say it again."
"Absolutely not."
"Too late." He turned her wrist over, gently, and ran his thumb along the inside of it, where the pulse was. It was hammering. Fast, deep, traitorous. "Your heart rate is about a hundred and ten, Team Leader. You want to arrest me for that too?"
"You're fired if anyone sees this."
"There's no camera in B. I checked my first week, for exactly this kind of contingency." He stood, never letting go of her wrist, and walked his free hand up the table until he was leaning over her, his tie hanging down between them like a noose waiting to be used. "Last chance to tell me to stop."
Her jaw worked. Her eyes, those eyes that had stripped six years off his ego, went from his mouth to his eyes and back.
"Lock the door," she said.
He was on it in four strides. The bolt slid home with a sound like a starting gun.
When he turned around she was up out of the chair, jacket already off, dropping it over the backrest, and she came at him instead of waiting. That was the part that nearly finished him: she grabbed his tie and hauled him in and kissed him like she was going to beat a confession out of him. Her mouth was hot and furious, teeth catching his bottom lip, and he groaned into it, hands flying to her waist, then her ass, dragging her against the hard length of him already straining at his fly.
She felt it and broke the kiss, breathing hard, her forehead against his.
"You're disgusting," she said. "I can feel you through your suit."
"I've been disgusting for about an hour, actually."
"I don't want to know." She said it while unbuttoning her blouse, so it didn't count for much.
The blouse hit the floor. Underneath, a plain white bra, no lace, no nonsense, the cups fitting her small firm breasts exactly. He reached for the clasp and she smacked his hand away and did it herself, watching him the whole time, and when the straps slid down her arms and the bra dropped, he made a sound that embarrassed them both.
Her nipples were dark and already hard. He bent and took one into his mouth without asking, and her hand cracked into the back of his head, holding him there, fingers twisting into his hair.
"Fuck." The word came out of her in a low hiss. He sucked, tongued the peak, felt it stiffen further against his tongue, and her hips pushed forward against nothing, searching. He ground his erection against her hip and she pulled his hair harder.
He worked his mouth down her sternum, over the ridges of her stomach, and dropped to his knees on the conference room floor. Her hands went to his shoulders for balance. He unhooked her trousers, dragged them and her plain cotton underwear down her lean thighs in one motion, and she stepped out of them, one shoe at a time, leaving her standing half-naked over him under the fluorescent light, ponytail slightly wrecked, and he had never seen anything so dangerous in his life.
"Tell me if I stop," he said, and put his mouth on her.
She was already wet, slick and hot against his tongue, and the first slow drag of it punched a sound out of her that she immediately tried to swallow. He refused to let her. He gripped her ass with both hands, spread her, and licked her properly, flattening his tongue against her clit and circling, then pointed and relentless, then sucking it into his mouth until her thighs started shaking.
"Yi-soo." His name again, wrecked this time, no warning in it at all. "Don't stop. Don't you dare stop."
He didn't. He fucked her with his tongue, two fingers joining it, curling up into her against the rough patch that made her gasp and grip the table edge, papers sliding everywhere. He could hear how wet she was, obscene and loud in the quiet room. Her hips started moving, riding his face, using him, and that was the filthiest thing he'd ever been party to: Joo Hye-ra, his devil, grinding on his mouth with her head thrown back and her ponytail coming loose again.
She came on his tongue with a short, strangled cry, clamping around his fingers, her whole body going rigid and then loose. He licked her through it until she pushed his forehead away, oversensitive, breathing like she'd run the academy course he'd failed six years ago.
"Get up," she said. "Get up and take your clothes off."
He was naked in under a minute, tie last, and she caught the tie before it hit the floor. She looped it once around his wrist and pulled him toward the table.
"Sit on the edge," she ordered. "Hands behind you."
"Hye-ra."
"You wanted me to ruin you. Sit."
He sat. She wrapped the tie around his wrists, a loose knot he could break in a second and both of them knew he wouldn't, and then she went down on her knees in front of him and took his cock into her mouth without ceremony.
The heat of it made his vision spark. She was ruthless at this too, no teasing, just her tongue and her throat and her hand working the base, taking him deep enough that he felt the tight squeeze of it and groaned loud enough to echo off the glass.
"Jesus, fuck, Hye-ra, I'm not going to last if you do that."
She pulled off, a thread of spit connecting her lip to the head of him. "Good. I don't have all night." She stood, braced one knee on the table beside his hip, and lined him up against her, slick and swollen and still twitching from her orgasm, and sank down onto him in one slow, brutal inch at a time while he watched with his mouth hanging open.
"Oh my God." His voice cracked. "You feel incredible."
"Shut up." She bottomed out, both of them gasping, and grabbed the back of the chair behind his head for leverage. "Shut up and let me work."
She rode him hard, hips snapping, the table creaking under them, case files for a suspected murderer scattering onto the floor around their feet. The gold-foiled invitation slid off the edge and landed face-up near her abandoned trousers, Y.S. glinting under the light, and neither of them looked at it once.
She picked up the pace. Her knees dug into the edge of the chair on either side of his hips, and she braced one hand flat on his chest, using him, riding him in hard fast strokes that made the chair squeak against the tile. His cock slid out of her until just the head caught at her entrance, then she slammed back down, taking him to the root, and the wet slap of it filled the room.
"Fuck, Hye-ra, your pussy is so tight." The words fell out of him, ragged and filthy, and he didn't try to take them back.
"Shut up." But her voice was wrecked, breathless, and her nails raked down his chest, leaving red lines across his stomach. "Don't talk. Just sit there and take it."
He took it. He watched her the whole time, watched her small breasts bounce with every downstroke, watched the flush spread from her throat down between them, watched her mouth hang open as she fucked herself on his cock like it was the last thing she'd ever allow herself. Her ponytail had given up completely, dark hair sticking to the sweat on her neck, and he wanted to tell her, wanted to say you look ruined, you look like you've been thoroughly fucked, but she'd told him to shut up and he was, for once in his life, obeying.
His arms strained against the tie, not to escape but to touch her. The knot held. The helplessness was doing something vicious to him, his balls drawing up tight, the pressure coiling low in his gut.
"Hye-ra." A warning, this time. "I'm close."
"Not yet." She ground down on him, circling her hips, his cock buried so deep inside her he could feel her cervix kiss the head, and she gasped. "Not until I say."
"You're going to kill me."
"I've been trying for six years." She grabbed the back of the chair with both hands and went faster, ruthless, her thighs trembling with the effort, the sound of her wetness around him obscene. "You don't get to come until I do. That's the deal."
"That's extortion."
"That's teamwork." Her voice broke on the last syllable. Her rhythm stuttered, hips jerking, and he felt it start, the flutter deep inside her, the squeeze of her walls clamping around his shaft. Her head tipped back. "Yi-soo, I'm..."
She came hard, crying out, no attempt to swallow it this time, her whole body shuddering as she ground down on him and rode it out. Her pussy pulsed around his cock in wave after wave, and the feel of it dragged him right to the edge, his spine arching off the chair, the tie cutting into his wrists.
"Please," he gasped, and hated how it sounded. Loved how it sounded.
"Come," she said, breathless, still shuddering. "Now. Inside."
He didn't need telling twice. His orgasm hit him like a wall, his cock surging deep inside her, pulsing, spilling thick ropes of cum into her with every heartbeat. She felt it and pushed down harder, milking him with her own contractions, her hand flying between her legs to circle her clit as his release flooded her, drawing out both of them until he was groaning and oversensitive and she was limp against his chest, both of them dripping sweat.
They stayed like that. His softening cock still seated inside her, her cheek pressed to his damp collarbone, their breathing slowly climbing down from the edge. Somewhere in the tangle of limbs the tie had slipped off one wrist. Neither of them mentioned it.
"That didn't happen," she said into his skin.
"It absolutely happened."
"It happened once. Past tense. It will never happen again." She pushed herself upright, and his cum leaked out of her as she did, a slow trickle down her inner thigh that they both watched without comment. She reached for her blouse.
Three sharp knocks hit the door.
They both froze.
"Team Leader Joo?" A voice, young, muffled through the wood. A junior detective, one of hers. "You in there? The Commissioner's office called, they need the Seong-won briefing materials before the team meeting."
Silence. Hye-ra stood motionless in her bra and nothing else, one trouser leg still hanging off her foot, staring at the door like she could incinerate it. Yi-soo, still naked with cum drying on his stomach and his cock shining with her, put a hand over his own mouth to keep from laughing.
"Team Leader?"
"One moment," she said. Her voice came out almost normal. Almost. She mouthed one word at Yi-soo with murderous precision: clothes.
He moved. He gathered his trousers off the floor in a crouch, hopping into them, and scooped his shirt up off the floor while she wrenched her bra on and dragged her blouse over her head, buttoning at speed, missing one. She kicked her underwear under the table, stepped into her trousers, and swept a handful of scattered case files off the floor with her foot in one motion.
Yi-soo looked down. The gold-foiled invitation lay face-up by the door. In plain view.
He flipped it over with his toe as Hye-ra unbolted the lock and pulled the door open wearing the exact same armor she'd worn all evening, ponytail only slightly suspect.
The junior detective's eyes went from her, to Yi-soo standing by the window with his jacket over one arm, to the faint fog on the glass. His expression did something complicated.
"Detective Jin," he said. "I didn't know you were in here."
"We weren't," Hye-ra said. "He was leaving."
"I was leaving," Yi-soo agreed, strolling toward the door. He paused at the kid's shoulder, adjusted his own collar, and smiled. "Briefing materials. Good luck with those."
The junior looked at Hye-ra. She looked at a point six inches above his head.
"Send them to my office in ten minutes," she said. "And close the door on your way out, Detective Jin."
He went. Halfway down the corridor he heard the lock slide home behind him, and he was still grinning about it when his phone buzzed. One message.
That was the last time.
He typed back with his thumbs, still walking.
Sure, devil. See you Thursday. Wear your hair down.
