you and ni-ki exchanged filthy words to each other at the same time, your voices were sharp and loud enough to turn your other coworkers heads. and even though they had long grown accustomed to your rivalry, they always still look at the two of you in shock.
it's like the office practically lived in fear whenever the two of you were around,
and it got to a point where the HR was already forced to intervene.
you both found yourselves sitting across from a visibly exhausted HR rep after a particularly heated argument during a department-wide meeting.
"l/n, nishimura... this is really out of control." they said while rubbing their temples. "you're sabotaging projects, disrupting meetings, and making the workplace hostile."
"tell her that. she started it." ni-ki pointed out.
you rolled your eyes.
"effective immediately, you're being reassigned to different departments."
and it should've ended there but somehow, despite being on separate teams, you both still found ways to make each other's lives miserable. you found loopholes and more ways to sabotage each other without making it obvious.
ni-ki took every ounce of restraint not to strangle you, and you might've run him over in the parking lot already if it weren't for security cameras around the building.
that late night, the office was already empty. you thought everyone had clocked out except for you.
you were also ready to leave, your bag is already over your shoulder but something was missing.
the important file, you knew you had just printed it.
"looking for this?"
it was the first time you saw ni-ki again. he's standing across the room, holding the folder between his fingers with a serious expression.
your stomach dropped. no fucking way.
"you're so fucking dead," he shook his head. "say goodbye to your career."
"gi-give me that!"
he held it high, stepping back when you tried to take it.
you almost had it but he made it more out of reach.
the folder has the confidential criteria of the next manager promotion, he knew you're a bad person but he didn't know that you'll just fucking cheat.
"yes, i'll give this back," he scoffed and nodded. "right to our manager."
your desperation turned to rage, that paper would literally ruin you. your eyes landed on a thick book sitting on a nearby desk, and you could've just explained and asked nicely to give it back but hell no, so you grabbed the hard thick book and threatened to swing.
ni-ki panicked, he looked around for a weapon of his own and in a split-second decision, he grabbed a cup off the desk and threw it at you...
very cold water splashed all over you and your clothes.
your jaw dropped. "you-"
"i- i didn't-"
then your foot slipped on the wet floor, ni-ki reacted fast, catching your head before you could crash to the ground but the momentum sent him stumbling too.
you groaned, his hands braced against the floor to keep himself from completely crushing you and next thing you knew, you were on the floor, your back against the cold tiles, and ni-ki was right on top of you, with his face buried on your tits.
he slowly moved, his eyes locked onto the view in front of him... your soaked blouse sticking to your skin, making your black bra and cleavage very much visible.
ni-ki cleared his throat before turning his head away from you. he was about to grab the scattered papers but you were quicker, you grabbed onto his collar, pulling him before he could escape.
"let go!"
"not a chance."
he struggled, trying to push you off but you were holding onto him so hard that the buttons of his shirt ripped, exposing his toned chest and abs.
you smirked slightly when you noticed ni-ki stopped pushing you away and his breaths became heavier.
he's still a guy after all.
your fingers roamed around his exposed chest, teasing him just to test something, to see if you could turn the tables,
you could feel his muscles tensed under your touch and ni-ki closed his eyes when you leaned close to give him a soft kiss on the lips.
the sound your lips made as they parted was too sexy so he leaned in to kiss you just to hear it again.
the kiss deepened, it became hurried, hard, aggressive, and messy.
like all his hate had nowhere else to go except right here.
ni-ki groaned against your lips, hands gripping on your waist.
you fingers slid down his chest, feeling the warmth of his skin more beneath the open shirt again and before you knew it, you were helping him remove his shirt off completely, tossing it aside like it meant nothing.
"this is unbelievable." he thought, while his fingers worked hastily, unbuttoning each one from your blouse with urgency, making your heart race even more.
"you're impatient." you whispered, breathless.
"just wanna get this over with." he said before his lips crashed into yours to shut your annoying voice.
you wrapped your arms around his shoulders as he easily lifted you, his other hand sliding down your back to remove your bra.
ni-ki watched the way your boobs bounce and spread free right in front of his eyes.
he lay you down on a nearby couch, removing your skirt and stockings so he can have you naked completely.
you arched on his touch but ni-ki grabbed your wrist and pulled you on top of him with no effort.
and even though you won't openly admit or say it, you knew everyone found your coworker is attractive but damn, he's this big too?
so now it made it harder to stop all this and it's been so long too since you had sex, you already forgot how it felt.
you watched ni-ki slicked himself with his own spit, barely easing what was about to come because just as you suspected, the stretch really hurts.
maybe it just the tip but it was already too much. your nails dug into his shoulders, desperate for something to hold onto.
ni-ki started moaning, his entire body tensing as he felt the way your walls squeezed around him. it's so tight, so impossibly hot too like you were already milking him for everything he had and his cock's not even fully inside yet.
"fuck," he groaned, "you're sucking me in."
yes, ni-ki hates you and even though he wanted you to suffer for everything you did to him, he would never be cruel when it came to sex. his own self-control was also hanging by a thread, yet he still moved carefully, pushing in slow and deep, letting you feel every inch of him.
your head tipped back, moaning too as you adjusted to his size, tightening more around him involuntarily.
ni-ki smiled, probably the first time he did. "there you go," he thought, watching your reaction as he rolled his hips up to meet yours, slow while keeping your legs in it's place.
you couldn't even think now already, the way he filled you up, the way his body pressed against yours, it was overwhelming. your nails raked down his back as he picked up the pace, going deeper, and deeper that you just might pass out.
and when the pain faded into pleasure, your body moved on its own, you rolled your hips until you found a good rhythm, lifting yourself slightly before sinking back down, to take his dick even deeper inside you.
ni-ki threw his head back, eyes squeezed shut as you rode him with no mercy, your warm, soaked walls dragging over his cock at a pace that was too much. it felt like he had no control anymore, he could barely think.
"y/n, slow down-" his voice broke, desperate and strained but you ignored him, rolling your hips even more fast because then maybe you'll get to see him snap.
his whole body was trembling beneath you, muscles tensed as his breath came out in sharp, ragged gasps. he already came once, and it had already been so deep inside you but you just wouldn't stop.
"you wanted to fuck me, right?" you taunted, your thighs were shaking from how much pleasure was coursing through your overstimulated body. "then just take it."
ni-ki buckled up into you too, he's so close again, teetering on the edge, but he refused to give in to your words.
"you- you're one to talk," he rasped, "when you're so fucking soaked."
and he was right, you could feel how drenched you were, could hear how messy and filthy it sounded every time your hips met his.
the pleasure became too much again, unbearable ache building deep inside you it felt like you're going to pee anytime soon, you pulled his hair for support as your rhythm started slowing down.
ni-ki noticed even through his dazed, wrecked state before smirking again. "gonna fall apart on me?"
his hands held your hips down, forcing his cock so deep inside you that your vision blurred, a sob tore from your throat as the pressure snapped, crashing through your body so intense that you couldn't even moan.
your lips parted, body trembling uncontrollably as you came hard on his lap.
you didn't know how but somehow now, he had you on your hands and knees, chest pressing against your back as he drove into you, relentless, unforgiving.
"n-no, fuck!" you sobbed, your arms nearly giving out as he buried himself inside you again and again, ni-ki's lips trailing over your shoulder, hot and ragged.
and your pussy clenched around him again, he started losing it.
his fingers tangled in your hair, pulling it to where your back can press against his chest, his other hand gripping on your throat.
he cupped your tits, you could feel his cock twitch inside you, the thrusts of his hips turned frantic as he chased his own release.
...now the office fell silent but the reality of what just happened started creeping in slowly between the two of you.
you reached for your discarded clothes, your limbs were feeling heavy as you clumsily pulled your skirt back on. ni-ki, still catching his breath, sat up to and started buttoning his ruined shirt though half the buttons were missing, making it completely useless.
then, he held something up between his fingers.
"can i keep these?"
your head turned towards him, eyes widening when you realized he was holding your panties.
you snatched it from his grip. "are you fucking sick in the head?" you hissed, slipping them back on as quickly as possible.
he just laughed and shook his head.
maybe he's sick, after all, he just slept with the worst person he ever knew.
next day you and ni-ki sat across from each other in the office, both unusually quiet. no bickering, no scheming, everything was just... gone.
your coworkers noticed but ignored it, just enjoying while it's happening.
ni-ki exchanged awkward glances with you before quickly looking away.
your lips were still tingling from last night. you swore that your body still felt him, and every time you move in your chair, the memories just keeps on flooding back to your head. "stop... please... oh, my god."
he wasn't doing any better too, he can't stop smiling and running a hand through his hair, his knee were bouncing under the desk every time his eyes landed on you.
then he caught you alone.
you were at the copy room, trying to focus on literally anything else when suddenly, you felt him.
ni-ki pressed up behind you, my dick misses you, is what he wanted to say. "what the fuck are you doing here?"
you blushed, your fingers were curling into the edge of the machine. "p- printing, what else?" you stuttered.
"y/n..." his hands found your waist, squeezing lightly. "you don't miss it?"
you swallowed hard before turning around to face him, "keep dreaming."
liar.
the asshole ni-ki you know would never say these things and if he did, the old you would've punch his mouth and punching it once once so you'd make sure it'll bleed.
so what happened?
"remember, i still got the files."
you hushed him, "give that shit back," you whispered.
he hummed, tilting his head. "it's at my house. you can come get it."
"just bring it here!"
"like i said," he dragged the word out, stepping closer, "come get it."
you still found yourself standing outside his apartment later that night even though knew it was probably a trap.
ni-ki opened the door, leaning against it with that same smug expression like he knew you'd be here... he's wearing nothing but a loose bathrobe.
you looked down. is he naked underneath? he's this pervert? then you quickly shook your head, forcing yourself to look back up. "where is it?"
he sighed, stepping aside to let you in. "hmm, i put it somewhere over there," he murmured.
you shoved him away before he could try anything, making him chuckle.
so you started searching, bending down to check under his sofa and through the mess on his coffee table.
ni-ki stood behind you, watching. no, he was checking you out.
his tongue slipped to wet his lips, looking at your ass and if he stared any longer, he knew his dick will get hard.
you stood and stomped your foot. "just give it back!"
ni-ki sighed and fixed his hair. "okay, fine!" he said, "i already shredded it. you don't have to worry."
"how do i know you're not lying?"
he didn't answer right away. instead, he leaned back against the armrest of the sofa, legs spreading slightly as he pulled you closer between them.
"because... you fucked me so good, i destroyed every single thing i have that could ruin you."
you swallowed hard, chest rising and falling hard as you look into his eyes then you looked down, and... oh.
his cock twitched beneath the thin fabric of his robe, already straining against it, making his arousal painfully obvious.
the air grew heavier as you both watched him get harder, completely shameless.
your lips parted slightly, heat creeping up your neck, but then you shot him a glare. "can you put some damn clothes on?"
ni-ki smirked, playing with the belt of his robe. "but you came all the way here…" he said. looking at you with his needy eyes.
he didn't finish his words, you just reached forward, curling your fingers around the soft fabric, and dragged it off his shoulders, inch by inch.
your eyes followed every reveal, his sharp collarbones, the defined lines of his shoulders, the smooth, lean muscle of his chest.
his eyes were locked onto your lips, red, and swollen from the night before. that's his doing and it looked so good.
his fingers traced along your jaw, his other hand gripping your waist as he captured your lips in a slow, deep kiss. his body was already hot beneath your touch, tense, waiting for you to take control and do him however you wanted.
you knelt between his spread legs, dragging your hand over his thighs, watching the way his muscles flexed under your touch.
you wrapped your fingers around his cock first, stroking him slow, letting your palm glide smoothly over him. his cock twitched in response with a shaky breath slipping past his lips.
you leaned in and pressed a slow, wet kiss to his tip. ni-ki's grip in your hair tightened but not pulling, just holding, like he needed something to ground him.
and when your lips wrapped around him, he lost all of his sense of control. you took him deeply that your cheeks were hollowing while letting your tongue glide over every inch of his dick.
you pushed even lower, forcing him down your throat, stretching yourself around him until your throat clenched, gagging as you choked when he hit the back of your mouth,
"more, more... more..." ni-ki bit his lip.
and you let yourself struggle, deep throathing his cock that spit started pooling at the corners of your lips, dripping down your chin, and all over your hands.
you heard him swore in Japanese under his breath so you can't help but chuckle, vibration sent another set of pleasure through him before you pulled away, letting his cock slip from your lips with a pop, thin strand of spit still connecting your mouth to his tip.
ni-ki's hips bucked, desperate for your mouth again but you just smirked, dragging your tongue along the side of his cock, slow and teasing, before wrapping your lips around him again... only to pull away the second he's about to cum.
"y/n- stop... that." he warned but you ignored it. instead, you just wrapped your hands around him, stroking him slow and lazy.
"you were close, right?"
"you think you're funny?" he panted.
you started sucking his dick passionately again, enough to make him think you were finally giving in but only to pull away again at the last second, lips barely brushing his tip, making him fucking ache.
his voice cracked, "you're so fucking evil-"
"you sound so desperate right now." you teased, dragging a single finger along his length, feeling how hot and hard he was in your grasp.
"you're not gonna make me cum?" ni-ki asked before pining your hands above your head, he had you completely spread out beneath him,
he's too far gone to even remember why he hated you in the first place.
and he went on you so hard that night, you couldn't even move the next day. you would fall the second you tried to stand, and the soreness between your thighs made you collapse back with a frustrated whimper.
a deep chuckle rumbled beside you, raspy from hours of groaning, moaning, and going crazy.
you glared at him weakly, when you tried again and failed, ni-ki carried you in his arms. you yelped, clinging to his shoulders as he carried you towards the bathroom.
he really did a number on you.
"think we can handle another round here?"
now he had your check pressed up against the cool, fogged-up glass of the shower. ni-ki's hands were everywhere, His large palms gripped the soft flesh of your tits, squeezing, pulling, and rolling your nipples between his finger, making your body arch back into him.
you just hoped that it wouldn't leave bruising prints on your skin.
you breathed hard, fogging up the mirror more, while your fingers kept slipping against the wet tile. ni-ki groaned against your shoulder, your fingers slipping against the tile for balance, wet slap echoing through the steam-filled bathroom.
"i could fuck you for days..." he declared, his teeth grazing your shoulder before he buried his face in the crook of your neck. His fingers dug into your hips, pressing you harder against the glass.
the water kept shifting from icy cold to blistering hot, and it's so hard to breath, like you were both drowning.
next morning, your body ached in ways you didn't think were possible, ni-ki groaned into the pillow beside you, his arm draped over your waist, refusing to move.
your phone buzzed on the nightstand, probably an alarm or a message about work. you glanced at the time, then at ni-ki, who peeked at you with a smile.
"we're not going in, are we?" he asked, still sleepy.
you sighed, already knowing the answer. "nope, i can't."
he grinned and rolled over, grabbing his phone to call in sick.
"i gotta go home."
he hummed, nuzzling against your neck. "mm. or you could just stay here with me."
his hand slid over your thigh.
"i'm so sleepy," you mumbled, voice muffled against the pillow.
ni-ki's fingers were already trailing down your side so you hissed.
"what?" he murmured against your shoulder, pressing a warm kiss there. "i'm just holding you."
"you're not."
sighed, eyes fluttering shut. "i need sleep."
...but he can fuck you back to sleep.
ni-ki hummed, pretending to think. he rolled on top of you, pinning you beneath his weight.
"just five minutes." he agreed, lips brushing your ear. "if not, i'm waking you up my way."
later, just as you were drifting into actual sleep, something heavy landed on the bed, startling you both awake.
your eyes snapped open, only to be met with a pair of little eyes glaring at you.
a dog.
a small, fluffy thing that was currently growling at you like you had personally offended it.
"what the?" he muttered, scrambling back. "oh, bisco..."
"your dog?"
"that's my child."
you blinked at him. "i didn't know you we-"
"yes," he replied, reaching to ruffle the dog's fur. "i'm a single father."
you squinted at him, then at the dog, who was still very much growling at you.
"oh, come on," you huffed, sitting up. "what's your problem?"
the dog barked in response, stepping protectively over ni-ki's chest. "bisco thought you were hurting me last night."
"excuse me?"
the dog growled again, and you shot ni-ki a glare. "are you gonna stop it?"
ni-ki reached out and pulled you against him, ignoring the dog's outrage.
"bisco," he called out, "you'll get used to her."
bisco did not look convinced. "i think it can sense your evil attitude," he teased, rubbing the dog's ears.
ni-ki looked completely at ease... messy hair, lips still a little swollen from earlier, and worst of all, smiling.
like actually smiling.
you swallowed hard, your face heating up.
was this really the same guy who had spent months making your life a living hell? the same guy who stole your reports, sabotaged your presentations, and threw every possible insult your way?
the same guy you swore you'd never tolerate, let alone you expect to wake up next to?
it really doesn't feel real.
you sat there feeling like your whole world just tilted sideways and yet, here he was, laughing softly as bisco licked his face, as if he wasn't the biggest opp you have.
ni-ki looked at you, "what?"
you scoffed, grabbing the blanket and pulling it over your head. "nothing..."
ni-ki only chuckled, moving closer, "tsk, don't tell me..."
and you kicked him under the blanket, smiling like an idiot.
