rating: explicit
word count: 3,5k
warnings: academic rivals. LOTS of dialogue and bickering. dubious science because i skipped it in school, had to do some basic chemistry revision to write this pornographic catastrophe, so please pat me on the back. rough sex? rough⊠foreplay, thatâs for sure. dirty talk, if you can call bickering that. penetration. reader tries to slap viktor, spits in his mouth and he cums in his pants. normally, i only write vanilla stuff, so i have no idea how it turned out THIS kinky (at least for me okay). not proofread (yet). nsfw under the cut:

âHow do you take your coffee?â
His voice betrays the feeble intention of civility, fusing that polite inquiry into a hissâa phonetic torture you didnât even know could occur before. So much for killing you with kindness. Outstaging quips by desecrating courtesies.Â
âI donât care,â you mutter on autopilot. Canât let him in on any personal preferences, no matter how insignificant. âJust donât put arsenic in it.âÂ
Viktor scoffs. Puts the kettle away and peers at you over his shoulder, all wretchedly complacent.Â
âSo the rest of the periodic table is welcome, I presume?âÂ
Viktor. The local Nikola Tesla knock-off. Never a moment of peace with him; and the fierce taste of competition grows coppery in your mouth whenever heâs in your sightâthe most handsome trigger of your cheek-biting reflex.
His name is an insult on your lips and you want to taste it. Chew it, crush it with your teeth and spit right out, preferably aiming for those poignant eyes seeking you in every classroomâso eager to light up with objection the second your opinion differs from his.Â
Always the first prick to disparage your input. A never-resting generator of all the meticulous ways to denounce your projects.Â
âIf I may.âÂ
Sickeningly polite, too. With that lithe finger pointing in the airâ so irritatingly comical. He may not, but there isnât a chance heâll shut up, now, is there?
And so heâd clear his throat, straightening his tie in that ridiculously solemn fashion. As if stepping on a pedestal to deliver a life-changing speechânot some shallow nitpicking regarding your circuit breakers. All eyes on him while his kept staring only into your soul. Special treatment, if you will.Â
You will not.
âUsing magnetic frames is careless,â heâd state. With his hand imposingly pointing to the blueprint on your slide. âCopper coils may oxidize. Not to mention the overheating. I would use thermoplastics. Theyâre significantly more efficient. And heat-resistant.â
Oh please. Like someone here gives a shit about what youâd use.Â
But you canât say that. Not in a room full of professors. And, judging from the countless nods of approval, the shits were, in fact, being given.Â
âToo risky,â you oppose. âThermoplastics often degrade at high temperatures. Electric insulation is not worth the damage of releasing hydrocarbons. I assumed that youâd be aware of that, Viktor. But I suppose that was an omission on my part.âÂ
More nods of approval, now in your favour. Here it goes againâthe ever-lasting spectacle of hatred. Elegant, when entertaining the audience. Anything but discreet, in private. A perpetually drawn game of chess. By repetition, not agreement. Both of you refuse to retreat until checkmate.Â
Oh yes, the sentiment was mutual. You and Viktor were notorious for tearing at each other's throats. The things youâd sacrifice to make that more than a mere metaphor, though. To pull him by that neat tie to sweet asphyxiation and hear him rasp for mercy with eyes full of pathetic condemnation. And he dreamed of that, too. His cane was itching to give you a smackâto paint your behind a plum so deep youâll have troubles sitting without wincing. When it came to making metaphors literal, heâd pick being the pain in your ass.
However, your mentors couldnât care less about the rivalry. The Collegiate Inventors Competition was coming up. And who could possibly make better candidates than two greatest minds of the engineering department, with academic excellence so accurately neck and neck that both of your names now occupy the honorary first place in every ranking table?Â
Thatâs how you ended up with your sentenceâthree weeks of after-hours cooperation in the lab with the incorrigible bastard himself, a quarter of which youâve already wasted on pointless bickering. Well, not without achieving some common grounds. The choice of prototype landed on one of your personal ambitionsâa wearable exoskeleton for post-surgery rehabilitation, with plenty of robotics involved. Endorsed by Viktor, for once. The greater good must have swallowed even his dispute. Off to a nice start, if someone were to ask you.
However, the first issues struck early: on the very stage of development. Viktor volunteered for modelling: meaning, the framework would be custom, to accommodate his spine specifically. An object lesson for everyone involved, it would seemâbut only in an ideal world. Which, considering what you had at hand (acrimony, bitterness, an entire picky bit of gall), was filtered out by default.
Now, five gruesome days and whoâs-even-counting-anymore restarts later, youâre nowhere near close to at least a draft, yet borderline keen on murdering each other. And youâre certain the latter is approaching. He did just contemplate putting arsenic in your cup, after all.Â
Viktor stirs the coffee. Watches his reflection smudge in the dark, whirly water, shooting you an askance glance from beneath thick brows when you start stirring yoursâthe spoon clanking a tad too loud, as if you were doing it on purpose. Which, you undoubtedly were.Â
âStop that,â he groans, almost leaping out of his chair. His heavy, disturbed gaze meets your cheeky simper. âYou donât have to stir it so thoroughly. Itâs not like you take it with sugar anyway.â
âOf course.â You shrug. âI donât drink slop.â
âOh, I figured. Thereâs nothing sweet about you, so why would your coffee be any different?â
âThereâs plenty of sweetness about me. I simply donât squander it on entitled pricks.âÂ
That finally grounds him. And youâre giddy for the way his sturdy hand grips the cup so hard that it almost shatters into his palm, knuckles growing pale enough to match the porcelain. More so when you take a loud, languid sip, feigning innocence. Fully wallowing in his darling, defeated speechlessness.Â
âExcuse you,â he mutters. âEntitled?!âÂ
âSo you agree with the âprickâ part?âÂ
âYes, and I take great pride in it. You may mark me flustered.âÂ
âDonât forget to bust in your pants.â
Viktor sneers: chapped lip twitching, scowl growing defensive. Lanky legs untangle as he rises to his feet, towering above you in an angry lean on his caneâlong frame transforming into your personal, scrawny menace, pissed exhale sharp and nasal above your head. And you admit to looking small beneath himâall hunched shoulders, weak smile finally tumbling lopsided.Â
âDonât you dare call me entitled,â he demandsâand means it. Itâs palpable in the way he twists the handle of his cane, the squeaky sound violently scratching your brain. âI sweated blood to achieve my privileges in this establishment.â
You huff, rolling your eyes. âSo did I, and yet you keep ordering me around as if Iâm some braindead apprentice. Weâre counterparts, Viktor. Youâre supposed to be mindful of my perspective.â
âI never see you being mindful of mine,â he counters.
And, well. You canât argue with that.Â
Your coffee break continued in avoidant silence, but the ambience simply reeked of hostilityâstifling enough to make you leave the lab feet first. The deadlineâs chokehold besieging your neck wasnât of any help, eitherâyou had to submit the draft for approval by Sunday. And, so far, you havenât even agreed on the design plan.Â
You shoot Viktor a reluctant glance. Pensive, he sat slouched over his parchment, emitting pure peril. Like his shoulder blades might stab you if you attempt a single tap, belligerently peeking through the thin shirt. You tucked your lip under your teeth, chewing hard, tongue running over every small, neurotic wound inside your mouth. Fruitless negotiations held a special spot amongst your least favourite endeavours, but this conundrum called for a desperate measure.
âViktor.â You winced at how chocked up it came out. He noticed that, tooâbecause of course he didâturning in his chair to nod at you, ever so shit-eatingly. Lancing eyes scrutinised their way up to your face. What an affront.Â
âYes?â Always chiding in that condescending tone of his. Hissy âsâ echoed in the lab, gnawing at your nerves.Â
âWe have to submit something by the end of this week. Letâs at least decide on the blueprint.âÂ
âFine.â He shrugged, returning to his sketch. âWeâre going with mine.âÂ
âNo!â You snapped. âWeâre coming up with a new one. Together.âÂ
Viktor hummed in mock consideration. The strand of hair heâs been twirling unraveled, claiming more attention than you deemed him worthy of. Sighing, he lazily reached for your graph, frowning as his eyes started skimming over the scribbles. You made your way to the desk, claiming a spot behind his shoulder. That required a tacit truce.Â
âYou really want to wield⊠hydraulic actuators?â He winced, looking up at you. Had your breath hitching at that respectful attempt, the effort prominent in the very way he uttered those wordsâas if struggling to filter out swear ones.Â
âYes,â you mustered. âFor high power.âÂ
âBut theyâre so heavy.â Â
âWell, what would you use?âÂ
He chuckledârich and malicious. Flipped the page and finally averted those curious eyes, arching a bushy brow.Â
âI thought no one gave a⊠crap about what Iâd use.âÂ
Oh, well. It felt nice while it lasted.Â
âHow did you evenââ
âYou ought to be more discreet with your vitriol,â he retorted. âIâll let you know that Iâm a decent lip-reader.âÂ
âThen donât stare at my mouth next time. What would you use, Viktor?âÂ
Now that left you both startled. His fingers stilled above the diagram, flexing in disbelief, hollow cheeks hued a puzzled rouge as you almost chomped your tongue off, showing an embarrassed curse back into the depth of your throat.Â
âAhem. Electric motors,â he chanted, pretending to overlook the slip-up. And for once, you were grateful for his tact.Â
âI see. Well, er⊠put that down, please.âÂ
He instantly complied, fetching a pen. Left you to reflect on your misery to the rhythmic sound of his scrawling, pressing a sweaty palm to his forehead.Â
âRight.â He sighed. âWhat about the power supply?â
âRechargeable batteries?â You suggested weakly. âLithium-ion.â
âVery well. Frame?â
âSomething durable. Titanium?âÂ
âAbsolutely not,â he scoffed, pushing the notes away. âWhy must you always insist on using the heaviest equipment?â
âI donât know, corrosion resistance?â You muttered back, hovering over him. âBiocompatibility?â
âThatâs perfectly manageable with carbon fiber!â
âSo it shatters after the tiniest bump? Bravo, Viktor, how ingenious.âÂ
He lurches forwardârigid breath quivering over yours. Close enough to crush that thick skull with your foreheadâif only you ventured, that is. But, alas, youâre not as brave just yet. Some brief eye-stabbing is about all youâre good for.Â
âFine,â he agrees, pulling away. âWeâll use aluminium alloys. Corrosion resistant and easy to machine. No one wins. Does that suffice?âÂ
âYes. Now will you finally let me take your measurements for the sketch?â
He doesnât answerâat least not verbally. Merely stands up and nods to the measuring tape, face still heavily contorted with displeasure. But you donât oblige just yet. How can you, when Viktorâs fingers suddenly reach for his collar, fumbling with the button? Andâoh noânow theyâre sliding lower, reiterating once, twice, thrice, until his chest (flushed, but that might just be wishful thinking) is fully peeking out, teasing the smooth scrap of ivory skin.Â
âWhat⊠are you doing?â You mumble, utterly startled.Â
ââŠUndressing?â He says matter-of-factly, looking up at you so askance as if youâd just asked him if the sky is blue. One more ministration and the shirt is neatly folded next to the parchmentâwaiting for you to be through with the measurements to be slid back on his bony shoulders.Â
âThat, I can tell,â you mumble. âWhy did you undress?â
Viktorâs gaze daggers into you again. âDonât tell me you were actually intending to measure me clothed? Can you not comprehend precision?â
âPrecision?â
âThe prototype is expected to cling to me. I donât see how thatâs achievable with my shirt onâ I assumed that was rather obvious.â
âShut the fuck up.âÂ
âAh, sweet civility. I even started worrying that other entitled pricks mustâve depleted your decorum, but it seems like you saved some up for me after all. Iâm flattered, reallyââÂ
You donât even register when it happens.
Next thing you see is Viktor seizing your wristâsternly yanking your slap off his face before it gets the chance to land there in a flared handprint. Nothing but pure rage and pricklinessâright where his short nails are lancing your skin, engraving an ugly bracelet youâll wear for hours.
Well, maybe there is something else. Something inexplicable, and tremendousâdeep in the way your eyes keep drifting southâwhere his pants sling low on defined hips, and the pretty trail of dark hair runs from navel to waistbandâno doubt circling exactly what you manage to make out in the convex slope of his crotch. And you want to slap him for that, tooâsonorous, and frenetic. Going in again with full force, but his force always turns out to be fullerâand in an instance he firmly twists your arm, pinning it behind your backâpale face barely five inches away from your flushed one.Â
What happens next is beyond any explanations. Later, heâll blame it on inertiaâthat stupid urge to maintain the speed, to stay in motion with your messy antics until some external force stops himâa simple need to claim you before the inevitable collision.
But thereâs no inertia in escalation. In the way his free hand grabs you by the nape and clashes agape mouths together, teeth bumping hard enough to make you consider booking a dentist appointment later. Not a sign of inertia when you grab him, eitherâa little clumsy through the sharp pain in your twisted armâbold fingers raking his scalp in a vengeful tug on his hair.Â
And itâs more than a kiss. If anything, it looks like youâre trying to eat himâtongue out and thrusting into his throat so fiercely that he gags on it, almost tearing up. Now you know what sheer desperation sounds like, and itâs grunting against your mouth, suddenly pitching to a pathetic moan when you grab a handful of chestnut hair and pull so hard that his eyes roll back, lean frame shaking under your violent approach. You use that startled momentum to try and pry your arm free, but he still keeps it in place.Â
âYouâre hurting me!â You hiss, attacking his neckâthe very one you always shamefully admitted to finding the sexiest any man can possess, and your teeth roughly pinch at his voice box, coaxing another whine.Â
âGood.â He groans with spite. âI hope I am.âÂ
And yet, he releases your aching arm, trading it for a calculated squeeze of your waist. But the audacity overshadows his little mercy. You instantly use the unrestrained privileges to force a finger into his mouthâastounded at the way he instantly opens up, almost mockingly pliant. More so when you spit on his tongue, sparing no shameâas if trying to rile him up beyond recognition. Grinning, when your saliva dribbles down his chin.Â
âAh.â He huffs, instantly licking up the remnants. âThank you. Ever so disrespectful.â
âYou havenât earned my respect,â you lie, nudging him towards the chair. Not even bothering to wait until he lands, impatient hands already messing with his beltâso treacherously earnest as you shake, unfastening the buckle, and the bastard chuckles at that, looking down at your eager work.Â
âThatâs a new low, then,â murmurs coyly, helping you into his lap, heavy head leisurely thrown back. âSleeping with someone you donât respect.âÂ
âFuck you.âÂ
âOh yes. Youâre about to.âÂ
You glare at him from under heavy lids, but the anger refuses to lingerânot when he stares back full of indignant awe, so clearly basking in your attention. With his cock half-springing out of undone pants, shamelessly twitching against your palm. And not a single breath was hitched to conceal his excitement.Â
âMust you always be so insufferable?â You reproach, pushing his hair backâtoo domestic for your own liking, and yet it doesnât feel unfitting. Especially when he leans into your hand, welcoming your touch on his sweaty foreheadâlike he wanted you to feel it fever up with want.
âNo.â He shakes his head. âBut if it can grant me this, Iâll triple the effort.âÂ
âWhat happened to new lows? You donât have a fraction of respect for me, either.â
âYouâre right.â He shrugs. âFractions could never encapsulate my tribute to you.â
And his hand slipped under your skirt, shakily crawling homeâprecisely where youâd never confess to needing him a mere minute ago. But the sentiment did a decent job at diluting your rancour. There came no protest when he introduced two long fingers into your underwear, openly gasping at the evident dampness. And you allowed him that with no regrets. Moreover, you helpfully sank yourself knuckle deep, wincing at the brief burn, arms wrapping around his neck as he sweetly looked up, seeking your permission. Which was instantly found in the pretty moan you spilled into his mouth, slick tongues back at their futile attempts to strangle each other.Â
However, your patience was running thin. As much as you wanted to indulge in proper foreplay, whatever masochistic dance he exposed you to had you in agony ever since it startedâand it was getting unbearable to ignore the ache, no matter how bad Viktor craved to postpone the main course.Â
Your thighs clenched hard as you crouched above him, fingers wrapping around the hilt to awkwardly line the tip up with your cuntâthe slick sound of it slowly sliding down suddenly igniting some tender bashfulness. Like you didnât just spit in his mouth with a vile smirk. Like he never had to confine you from slapping him in the face.Â
That stretch felt different from the one after his fingers. Significantly richer, it made you whineâa pitiful sound reverberating against his skin as you held on tighter and allowed him to bottom out, savouring every little crevice inside you. Raw, yet neither of you seemed to careâthat concern was pushed alongside your underwear, then forgotten altogether when your walls clenched him, offering tight bliss.Â
âMove,â you demanded, grabbing him by the chin. Viktor rasped something back, but you didnât catch itâalready too busy tongue-fucking his pretty neck, turning your teeth into sharp tools ready to stain it mauve with bites.Â
And he complied again. One hand trembled on your hip while the other crawled between your legsâfirst missing your clit in the chaotic pace of thrusts, then finding it again as it grazed his fingertips. So cheeky when he dared to pinch it, avenging every pull on his hair. Though, he couldnât gloat in your wince. Not when it clearly was one of the pleasured kind.Â
But you didnât feel like letting him regain composure. You already missed his husky groansâached to test what else fucking you could make him mutter. Fogy gaze found his face again, softening at the sightâall wet forehead full of concentrated creases and thin lips bitten to bloodless paleness.Â
You took over. Let him lean back and rest as you roughly rode him into the chairâand for that he gave you a grateful moan, the insistent thumb toying with your clit never stopping even for an instant. Good with his hands, and he knew itâproudly grinned when you struggled to keep going, taut legs treacherously giving up astride him.Â
That didnât please you in the slightest. You wanted him to be close, too: slid a hand up his chest and angrily tugged at one nippleâchortling when his mouth dropped in a stunned gasp. Bewildered, but he didnât mind itâamber eyes squeezed shut when his head lolled, and you finally got his lovely moans backâraspier than before, ravenous enough to make your head spin.Â
You could already feel it, pulsing somewhere deep within. Blurry vision couldnât make him out anymore, the lab smudging into a mess of weird shapesâyou were about to cum, hard, and Viktor threatened to follow suit any secondâhis thumb failing to hold steady, and yet the pressure was still there, courtlesly helping you chase that sweet relief. Such a gentleman.Â
âClose,â you chanted. âSo, so close.âÂ
âI know,â he answered, choking on a groan. âMe too.âÂ
And you melted, almost crushing him with your weight. Quivering in a spasm so intense that it had him struggling to keep moving, and yet he was mindful of the riskâused the last fractions of his brain capacity to gently nudge you off his cock and pump it fast and hectic. Cumming in one endlessly thick rope, with a moan so vocal that it reached you even through the layers of foggy, ear-buzzing aftermath. Had you shuddering when you clung off his shoulder, glassy eyes wide with trembling astonishment. You stared at him through the approaching wave of disbelief.Â
No signs of regret so far, or maybe it was simply still formingâfor now, you silently admired not a snarky bastard, but a pretty, fucked out boy beneath you.Â
âOh, would you look at that.â Viktor chuckled, sheepishly looking down. âI didnât forget.â
âWhat?â You mumbled in confusion, following his gaze.
And when it finally caught your attentionâsticky and relentlessly staining his pantsâyou slammed a hand over your mouth, muffling the hysterical laughter.Â
âAnd here I thought I finally fucked your remarkable memory out.â
âOh, by no means. As, eh⊠intense as that was, that misery of mine is not going anywhere. However,â he trailed off, his hand skittishly moving towards yours, âsex clearly proved beneficial for our⊠dynamic.â
You smile, sliding your palm into his warm grasp.Â
âCan it ensure us enough civility to win the competition?â
And Viktor scoffs, coyly looking you in the eye.Â
âWhy should we limit it to just that?âÂ
