cw: nsfw, blow-job, piano witnessing oral sex i'm so sorry

summary: being neighbours mean being mindful of the noise you make - though, you'd been set on being a nuisance through violin solos, bringing Viktor to your doorstep to plead for silence. You decide to apologise.

tags: modern au, physics professor viktor, gn!reader, neighbours, nsfw, sexual tension, suggestive physics & music talk, blow job, fat set up beforehand, not betad

a/n never written comedy nor smut but at some point a girl's gotta try (why are both almost equally difficult) - but here ya go (plops down this mess). also, i'm more familiar w music than physics, i 3rd page googled the latter so there's def smth not quite right. if u know physics, no u dont.

and ty to an anon ask for pointing out a mistake in the pronouns. i intend one shots to be gn but i write back and forth from an f!oc fic, resulting in she/her ending up in one shots and they/them on the other :')) entirely on me for not catching those before posting though - but thank you for notifying me, i appreciate you!!

Viktor had repeated it ad nauseam—keep the overtures to a minimum.

His days are a gruelling marathon of lectures and lab work, stretching from the crack of dawn at 6 AM to the academy's closing bell at 10 PM. This self-imposed siege isn't mandated by the university—no, they frown upon such academic masochism.

Rather, it’s Viktor's desperate attempt to squeeze productivity from the fleeting moments of silence. The irony? The moment he shuffles home, key turning in the lock, his apartment transforms into an impromptu concert hall.

Attempting to grade papers? Constructing intricate lesson plans on quantum mechanics? Preparing for the department's annual "Explain Your Research to a Five-Year-Old" challenge? Hah. Another pipe dream of this beleaguered professor.

No, instead, he’s treated to a violin solo that would make Paganini nod approvingly in his grave, some overture to madness waiting to ambush Viktor the instant he dares to sit down and tackle his workload. And the cherry on top? The virtuoso had chosen the room directly behind his study as their personal rehearsal space.

Tonight, Viktor's reaching his breaking point.

One more pluck of that violin string, and he might just snap (hopefully with more panache than his freshman physics students' failed bridge-building projects).

He's hunched over his laptop, a harsh '02:24' glowing on his wall—a neon reminder of how little he's accomplished in far too many hours. And there it is again, that infernal violin leaping across frets, notes ping-ponging between octaves with reckless abandon.

This time, it feels personal. A taunt aimed squarely at his last shred of sanity.

Viktor's fingers rake through his dishevelled hair, tugging in sheer frustration. His other hand thunders against the wall—once, twice, thrice. Stop. Stop. Stop.

For a blissful moment, the last note wavers, then fades.

Silence descends. Relief washes over him.

But his reprieve is short-lived. The melody resumes with a vengeance—louder, closer, more petulant and frenetic. It's as if the laws of acoustics themselves have conspired against him.

God, if you’re there…

Viktor can feel his grip on rationality slipping. Perhaps it's time to conduct an experiment on the effects of sleep deprivation on a physicist's patience. For science.

Your paths had crossed in the hallways, a silent slide of avoidance. You’d exchanged fleeting glances, loaded with unspoken frustration, before hurrying on your separate ways.

Viktor had made the pilgrimage to your door three times, his voice dripping with forced politeness as he implored (bordering begging, not his finest moment) you to relocate your impromptu concerts or, at the very least, reschedule your sonic assaults to more reasonable hours.

You’d exchanged names, plastered on smiles that never reached their eyes—and yet, your solos persist.

In moments of weakness, Viktor's traitorous mind can't help but wonder what camaraderie you might have shared in an alternate universe where you weren’t the bane of his existence.

He finds himself muttering a desperate prayer to the gods of acoustics: "Grant me the strength not to bash my head against this wall." He pauses, another side of his brain kicking in. "Although, the resulting concussion might make for an interesting case study."

A groan escapes him as his forehead meets the desk with a dull thump. (Might you want percussions, he could supply his head banging against his desk)

His mind, addled by sleep deprivation and the constant assault, contemplates the unthinkable—actually standing up for himself. God forbid.

He envisions marching to your door, pride in tatters, ready to beg, plead, perhaps even grovel for a moment's peace.

The image of his students receiving paper feedback that reads like the ravings of a madman flashes before his eyes. No. Nope. This cannot stand. Something must be done.

Then another image invades his mind: your door opens and there you are face to face once again.

He grudgingly admits you’re… aesthetically agreeable. He supposes. Mathematically pleasing. Something about proportion, bone structure, genes, something, something, and—no, there is an undeniable artistry in your relentless dedication. Which he respects.

Even through the wall, he can discern the masterful control of your bow, a testament to hours of practice that simultaneously impresses and infuriates him.

If he could be granted such hours to achieve his own goals, he'd surely rule the world (or at least figure out how to soundproof his apartment).

There'd been one night—one treacherous, sleep-deprived night—when his exhausted mind careened off the rails of rationality into dangerously uncharted territory.

He envisioned himself barging into your apartment, a perfect storm of righteous fury and academic gravity. In this fever dream, he demanded silence with an authority cobbled together from an unlikely triumvirate: his stern Professor alter-ego (complete with imaginary tweed jacket), the ego-inflating gravitas of his hard-earned Ph.D., and the bizarrely suave confidence that only exists in the realm of 3 AM delusions.

But in this warped fantasy, instead of blessed quiet, he encountered something far, far worse—a scenario that defied even the uncertainty principle in its improbability.

Sharp gasps cut through the air. Delicate moans rolling against the nape of his neck that it sent shivers down his spine. And then—oh, sweet laws of thermodynamics—his name. His name in repetition, wearing the throes of... No. Stop. Abort mission.

Viktor's eyes snap open. Heavy breaths. His heart rate approaches escape velocity, threatening to launch his ribcage into orbit.

He shakes his head violently as if the motion could dislodge the inappropriate thoughts from his brain.

"Fuck off," he mutters to the empty room, to his unfaithful imagination, to the persistent violin notes that seem to mock his predicament. Fuck it all. And fuck you. Well… No—(he means yes (no)).

A few times since your initial encounter, Viktor had been subjected to a different kind of midnight sound through the walls. These weren't the familiar strains of a violin, but rather... a more primal composition. Something more akin to pleasure than anything Stradivarius could have conceived. 

The truth was, these… vocalisations had rearranged his synapses, had opened up an entirely new neural pathway in his brain, one he had staunchly refused to acknowledge before. It was a new theorem of attra—intrigue he wasn't quite ready to solve.

Each breath, groan muffled, was a data point on his imaginary graph. To study the patterns, the crescendos, the duration. The other man in him... well, that was a variable he dared not allow to factor into the equation.

He found himself both dreading and anticipating these unintentional (at least he surmised so) performances. He'd catch himself straining to hear, then immediately feel a rush of guilt and self-loathing.

He reaches for his coffee mug, grimacing as he swallows the cold, bitter dregs. Clearly, this is what happens when a brilliant mind is deprived of its required REM cycles. Yes, that's it. Just the cruel tricks of an overworked, under-rested brain. Exactly.

His mind kicks into overdrive, frantically scribbling a mental grant proposal: "The Effects of Sleep Deprivation on Auditory Hallucinations and Improbable Fantasies: A Case Study." Purely for academic purposes, of course. (his mind lingers on improbable)

It's not like he's terrified these forbidden thoughts might return, more vivid and enticing than a perfectly aligned experiment. And it's certainly not because he's afraid he might enjoy—no, no, no. He minds. He minds with the intensity of a supernova. 100%. No, make that 100.1%, just to be safe. Exactly. Precisely. Quantum-mechanically determined.

Now, if only he could convince his subconscious of that irrefutable fact…

His eyes dart to the wall—that infuriating barrier of plaster and wood—separating him from the object of his des... deliberation. No, that's not right. The source of his frustration. Yes, frustration. A frustration so profound it could light up a small city.

He groans, burying his face in his hands.

The things sleep deprivation does to a man. It's enough to make even a rational physicist question the very fabric of reality.

But admiration be fucking damned—his frustration reigns supreme.

Viktor straightens up, a manic glint in his eye. Perhaps it's time for a little experiment in human behaviour. After all, every action has an equal and opposite reaction, right? Let's see how you’d like a taste of your own medicine—played back at 3 AM through a wall of subwoofers tuned to the resonant frequency of your floorboards.

No, no—Viktor, don't stoop. Just knock on their door.

A grin spreads across your face when a comically polite knock interrupts your crescendo. Ah, the sweet sound of success—or is it the dulcet tones of a professor’s patience snapping?

Oh, he's ever so gentle, even when he's one decibel away from a meltdown. You can practically hear his teeth grinding in perfect harmony with your last note.

You settle your violin and bow on the couch like a general laying down arms after a victorious battle. One palm reaches to massage your jaw, soothing the tender spot where your instrument has been resting. Who knew revenge could leave such visible marks?

Note to self: next time, consider a less physically demanding form of payback. Maybe take up the theremin? Start haunting him.

Though you're getting the creeping suspicion he doesn't know what he did—and it's entirely plausible that you just look like a nocturnal nuisance with perfect pitch and an impressive bruise. But hey, what's a little psychological warfare between neighbours?

Besides, it's fun crossing him in the halls, eyes following each other like two notes slowly coming in accordance, like a particularly flirtatious harmony. You're both knowing, sharing a secret thing. Well, as secret as a loud violin solo at 2 AM.

You reach the front door and turn the lock, swinging it open with a dramatic flair.

Leaning on the frame, you plaster on a grin that could outshine the brightest spotlight—and is sure to make the dear professor's blood pressure skyrocket. "Viktor," you greet, your voice a perfect pizzicato of feigned innocence.

As expected, he's the very picture of academic despair: dark under-eyes that could rival a raccoon's, hair ruffled in a way that screams ‘Sleep? What sleep?' (who knew sleep deprivation could be so becoming?), and a brow so furrowed it could host its own mountain range.

Huh. Interesting. Seems like the composed professor facade has taken an unexpected intermission.

You force yourself to keep your eyes on Viktor's face, resisting the urge to conduct a full-body visual scan. Tonight, you're oppositions. Stubborn ostinato. O-ppo-si-tions.

Oppositions don't ogle each other's physiques or linger on sartorial choices. That would be absurd, a complete discord in your carefully orchestrated revenge. Which is why you don’t see that he’s wearing a thin tank top, and why your eyes don’t hopscotch across the vague outlines of his chest.

Viktor grumbles your name with a frown, his accent turning the syllables into something between a growl and a plea. It's music to your ears, really—a different kind of melody, but no less satisfying than your midnight sonatas.

You wonder what else he could do with that voice. No—you don’t wonder. O-ppo-si-tions don’t wonder.

Rather, you flatten your lips, desperately trying to hold back a laugh that threatens to escape.

"Please," he breathes, the word carrying the weight of a thousand sleepless nights.

You cock a brow. "Please?"

He glares, his eyes boring into you with the intensity of a conductor silencing a wayward orchestra. Not finding me funny, you note mentally.

Well, tough crowd. But then again, you didn't take up the violin for the standing ovations, did you?

"How can I help you, Professor?" You smile sweetly, crossing your legs. "You're looking positively... nocturnal," Your eyes dance over his dishevelled appearance, drinking in every delicious detail.

You know that he knows that you know what you're doing. It's a duet of mutual awareness—simple, really—and satisfying.

He squeezes his amber eyes shut, his mouth a taut line of frustration. You half expect his hair to stand on end. Orchestra on their heels after a baton’s click-click-click.

That little mole above his mouth twitches, and you imagine it as a staccato note. There's a twin on his right cheek. You wonder, idly, if they'd dance a jig if you played just the right jaunty tune.

"Why," he begins, his voice a crescendo of exhaustion, "Are you doing this? I can't keep my head in tune with you behind that wall, turning my brain into jelly with your... your..." he gestures wildly at your apartment, as if trying to conduct your imaginary orchestra into silence.

"Oh? And what's wrong with exploring some alternative fingerings now and then?"

His eyes lock onto yours, widening slightly. He blinks, frozen—a maestro who's just realised he's forgotten his baton.

Ah. Are there actual discordant thoughts lurking in that brilliant mind of his?

What's a little push? You lean forward. "Care to demonstrate these unconventional techniques of yours?"

A gulp rides down Viktor's throat. A nervous glissando. A viola quivering. His eyes suddenly find your front door fascinating. "Look, I just want to be able to do my work, finish what needs to be finished, and get some actual sleep. Aren't you tired of this too?"

Your mouth pitches downwards in mock contemplation. "Mm... I get plenty of sleep in the day. Unemployment generally gives you a lot of time. Besides, payback is payback. This is simply the retribu—"

"Payback?" His face contorts into a mask of confusion that would make Picasso proud. Ah. So the maestro doesn't know his own composition. Tsk.

You straighten yourself, arms still crossed sternly. "You—" you sigh, brows pulling together.

"What," he huffs, clearly lost. His mouth slightly gapes open, eyes glancing to the side as if somehow the answer will appear.

lLast month. Seven PM. You're home with what I assume were your students," you gesture at his door. "Don't know what you were doing, none of my business. However, it does become my business when they stay over until four," you hold up four fingers at his face like a metronome gone mad, and he backs away. “In. The. Morning. You try sleeping with rowdy, hormonal young-adults screeching about the universe and quantum-this, quantum-that,"

He brings his hand up and rubs at his neck, looking everywhere but you.

"And I, not having slept in god knows how long at that point, had an audition for an orchestra later that morning," at this point his expression is completely soured, realising where this is leading. "And guess who bombed that and missed a potential orchestral debut?" you point at yourself with both thumbs, "First chair of the Insomniacs Anonymous Symphony,"

He brings his thumb and pointer to the bridge of his nose, worrying at his bottom lip.

You can recall a few times you’d burrowed your teeth in such a manner. Recitals. A particularly tricky passage in a Paganini caprice. On your couch with hand at the crux of your thighs rubbing gently to some fantasy. Nothing specific.

You stare for a moment, mentally composing a scream for the cosmos. How dare he look like a dishevelled maestro when you're trying to channel your inner fury? Not the time, brain. Not. The. Time. File that image away for later...

“I..." he begins, but the words seem to have gone on strike, leaving his mouth hanging open. Forgotten fermata.

A furrow grows on your brow, deep enough to nest a whole string section. His guilt-ridden silence gives you ample time to become distracted. Truly not the fucking time. But your eyes—oh, what rebellious instruments.

But fret not (hah), as you don’t discern much of his arms—not lean, nor precise. Not those fingers either, no. They’re not that long. You didn’t even notice. And not the slow rise and fall of his chest, rhythmic as a metronome in a world where time has suddenly become very, very interesting.

He says your name—it’s a baton raising in the air—and it wrangles your attention. “I truly... I apologise. I do admit... that night was foolish. I'd lost control of my class. I'd invited a few over since they wanted a discussion on quantum entanglement,"

Yeah, I know entanglements. What.

Your brain performs an emergency shutdown and reboot. “Uh-huh," you manage, trying to sound like you absolutely know what that means and aren't at all imagining him demonstrating the finer points of entanglement. Because you aren’t. O-ppo-si-tions.

You shake your head, imagining your thoughts like shaking a tambourine. Focus. Revenge. Missed opportunity. Right. But why does righteous indignation have to be so hard when he's standing there looking like Einstein's hotter, sleep-deprived cousin?

“And the discussion just… I wasn’t careful with the time,” he leans forward, mouth downwards in apology. His fingers tap on his cane, mouth sucking on one side of his bottom lip.

He looks miserable. And worse, genuine. Two things that never sit right with you when they happen at the same time. A string just slightly off tune that it settles as unease in your stomach. It gives you the itch to fine-tune it, put it back how it should be.

You give Viktor a resolute nod, blinking away. “I accept your apology,” you say shortly, gaze lounging on the hallway and making sure they don’t linger on his misery.

But he searches for you eyes first, and by obligation you look back. “And have you, has there been any opportunities after then?” he asks, leaning forward, brows tilted in genuine, apologetic curiosity (your heart decides it’s now a great time to perform an accelerando. 95 bpm, if you’re counting). “Auditions and… orchestral… things? Sorry, I’m not too knowledgeable on these,”

What’s good: he’s genuinely apologetic, which may herald the end of your musical tyranny.

You lean your head backwards, aware of the distance (What’s not good: he seems unaware of the distance he’d taken up). “Uh, no. Well,” you shrug, shoulders bobbing in reminder. “Not since then. But there’s one next week. Piltover Grande Hall,”

His brows raise, seemingly in recognition. “Oh? Highly-esteemed,”

“I know. I’ll probably need a good sleep before then,” you grin, watching his face go from confusion, to apologetic, to relief in mere seconds.

“I also… I assigned some heavy research work last week to my class, which’ll be submitted tomorrow, so I’ll be grading those next week,” he added, now fully leaning on your door frame as if his upper body were trying to slink inside slowly. “We’ll both need much rest before then,”

Your eyes meet his. Face fully facing face. “Mhm,”

Prelude: “An observation of observation of observation”. String section, sweet, curious, and swelling with playful remarks. Interrupted by staccato heartbeats, conflicted by seductive cello whines.

You don’t move. Not an increment. You stay as still as your body allows, suspended in time. So does he. His eyes flicker between your left and right, expressing nothing but obvious observation of you. Your stomach breeds a butterfly when you catch his gaze dropping briefly to your mouth before flicking back to your eyes.

Interesting.

100 bpm.

No. I, “Where The Gaze Lands Will Determine The Night’s Fate”. A languid 4/4. A lone marimba begins—blithe. The chirp of a güiro.

“And what do you propose?” you tilt your head up. Are you challenging him? Depends, you suppose. Depends if he tilts his face down.

But he stays in position. Instead, brings a hand out, palm open. “A truce,” his breath brushes against your chin. Hot. Temperaturally. Temperamentally.

Does he know what he’s doing to you? There are desperate sax whines in your head. Supposedly they sound similar to the human voice.

You take his hand and shake firmly. But you don’t let go. “What are the terms?”

A soft huff of a laugh escapes him, eyes slightly narrowing. “But you’ve already agreed,” his fingers tighten slightly around your hand. Warm. Long.

“Confident in the final piece,” you assert, letting your eyes drape with leisure between his eyes and to the bone of his cheek, the mole, the mouth. And you hope he notices.

The sax is breathy. It’s now a smoky jazz riff, painting dimly lit rooms, whisperings of sweet-nothings, a daring foot hiking up another’s thigh.

Your travelling eyes seem to catch his breath.

No. II: “Where Silence Is Relative”. Strutting 2/4, beginning with a sultry glide of an accordion. A conversation between the cellos and violins.

“Does that mean you’ll rest your little concertos?” his head tilts. “Giving me peace, finally?”

You play up a pout. “Shame, I thought you were a fan,”

“As I am of quantum tunnelling through a brick wall,” he responds, the brief questioning curve of his brow indicating this was not a good thing.

“Surely my playing isn’t that bad?” a smirk.

“Not the quality, no,” he gives a small shake. His thumb softly brushes your hand. “It’s the quantity. And the timing,”

You soften your fingers, letting the tips of them brush at his wrist. “I was trying to be helpful. Heard scientists appreciated background music while working,”

A glint of something playful in his eyes. “We do. Just not at 3AM when we’re trying to grade important papers,”

“Grading?” you quirk your brow and smile. At this point, it’s far from grating to him—he’s even looking at it. “I thought silence was overrated in the pursuit of knowledge,”

“Silence is relative when you’re next door,” he gives back. His hand is now shameless, inching your closer and closer to your wrist.

You wet your lips and hum. “Relative, right. Like, whose is that—like Einstein’s?”

“Like the relative pitch of a jackhammer compared to your violin,” his expression flattens sardonically, still maintaining that disarming smile.

“I’m touched,” you lean your head on the door frame. “You think I’m as powerful?”

“Enough to redefine my understanding of ‘noise cancellation’,” he retorts, eyes rolling. What a pretty expression that is. You wonder how else you can evoke that same reaction in other contexts.

“If you ever want a demonstration…”

He laughs. “I think I’ll stick to my textbooks. Much quieter,”

You feign a mask of disappointment, gaze sharpening and hooking his eyes in for your next few words. “Pity. I was hoping to show you how good I am with my fingers,”

His mouth parts. Surprise? Temptation? But he’s hooked in and it’s all you care for. “I… uh,” he blinks, hand still around your wrist. “That’s…”

His face fills with a slight impassive contemplation, thoughts seeming to run amuck in his head as he looks down at your growing, teasing smile.

“You’ve been hearing me practise, no?” you smirk. And you can tell he knows that you know that he knows what you mean. “The violin’s not an easy instrument. Unless you’re thinking of something e—”

He diminishes the space between you with his lips on yours.

No. III, “A Swing in A#”. 113 bpm. A confident, gritty trumpet reels you in.

The door shuts and is immediately faced by Viktor’s back. His neck bends to accommodate the difference in height, his free hand at the back of your neck to press you closer to himself. Your hands find purchase around his shirt, curling around the fabric, pulling and pulling—but as he’s leaning, only his hips jut forward. Good enough.

Your mouths move in tandem. He’s occupied with your bottom lip in a sort of desperation that speaks of practise—or at least imagined practise.

You nudge upwards, hip bone meeting his in soft collision, which coaxes a filthy, back-of-the-throat grunt from him. You smile. And as you feel his other hand snake around your waist, you hear the metallic thnk of his cane against the floor.

You jerk away to look down at it. Briefly, you assess its importance and his dependence on it. “Your leg,” you breathe, breath barely allowing your real voice to pierce through.

He’s nuzzling at the side of your face, gaping mouth at your cheek as he catches some air. “I’ll manage,”

When you turn to him, your heart jumps at the sight of him. Dishevelment caused by your hands, a slight flush from arousal, eyes rounded and trained on your mouth. You don’t look but can’t help noticing the hardness pressed against your lower belly.

“It doesn’t hurt?” you ask.

He shakes his head and finally draws his eyes back to yours. “A… discomfort. But not pain,” he dips in for a kiss, hand sliding up to tilt your jaw towards him.

A smirk becomes of you. “Mm… about the, uh… retribution. I do admit, I took it too far,”

His eyes widen in mock surprise. “Did you? All those unproductive nights, I truly didn’t notice,”

You roll your eyes at his quip. “But I was thinking of how to properly apologise,”

He quirks a brow, thumb tracing at the border of your lip and chin. “And how will you show your remorse?”

“Ah, well, I’m just like you,” a soft laugh escapes you, and you lean towards him to hide the slight embarrassment rushing to blush your cheeks. “Thinking all about… entanglements,”

“Do, please, demonstrate your version,” his accent noticeably makes ‘demonstrate’ even sharper and more pronounced.

“Only if you talk about yours,”

With a swift kiss, you silence him, lips capturing his words. Your hands grip his body, gently guiding him away from the door. Viktor's eyes, intense and unwavering, remain locked on you as you lead him a few feet to the side to the upright piano.

In one smooth motion, your foot hooks around the piano bench, sliding it out. Your hands, warm and certain, travel up to Viktor's shoulders, guiding him down onto the seat with a gentle and firm pressure. His gaze never falters.

For a breathless moment, you tower over him, drinking in the sight of him. He's even more deliciously undone—hair tousled, shirt askew, lips slightly parted.

The room seems to shrink, the world narrowing to just the two of you. You're minutely aware of every shallow breath, every subtle shift of his body, each time the muscles in his neck form a 'v'.

Something all-consuming takes root in your core, to hear his voice wearing your name—not just spoken, but gasped, moaned, worshipped.

“So?” you prompt. “Begin,”

No. IV, “Viktor’s Recitative”. An accented voice searching for focus. Punctuated by gasps.

“It’s, ehm, quantum entanglement. Imagine two dancers, perfectly in sync no matter how far apart they are. When particles become entangled, they share a quantum state. If you measu—”

With your leg you push his knees apart.

“Uh, if you measure one, you instantly know about the other. As if… as if connected by an invisible thread of… mm, cosmic intimacy,”

You kneel slowly, gaze locked onto his as he searches for his next words. “Rather romantic,” you add.

He swallows. And you take it as a suggestion.

“I think so, too. Two particles, forever intertwined,” his eyes fall to your hand as you palmed one knee, your head resting on his other leg. “Fates… linked across the, the vast…ness of space and t—time,” he jerks forward as your hand pressed a little too near his centre.

The sound makes your breath hitch. More. Your cheek’s brushing against the cotton of his pants, your other hand cradling around his calf. The hand on his knee roams further upwards, thumb applying more pressure on the ins of his thigh.

“Regardless of distance, still they influence each other in ways we can’t f—” he breaks off with a whine as your palm grazes the growing swell beneath his pants. It takes every ounce of self-control not to grasp him fully, to feel the entirety of him at once. “Fully…” his eyes follow where you press harder, your mouth curving into a smile. “Comprehend,” the word falls with more breath.

He leans back against the piano, elbows weighing down keys and sending a jarring, discordant chord alongside his sighs.

You straighten, bringing your other hand to the knot of his waistband. Your finger hooks onto it, thumb caressing the single button. Your gaze travels upward, admiring the sight of him leaning back, his shirt riding up to reveal a tantalising glimpse of hair trailing downward.

His breathing slows, becoming deep and measured as your finger grazes the skin of his stomach, the fine hairs tickling knuckles. For a moment, you imagine yourself above him, watching him squirm as his eyes fixate on the point where your bodies would join. Another day.

With a deft movement, you pop the button free. Leaning in, you catch your lower lip between your teeth as your hands gently guide him from the confines of his boxers.

His form arches slightly to one side, living sculpture of desire. Delicate ridges trace his length, and at the apex, his glans gleams like a ripe cherry. Tempting fruit begging to be tasted.

Deep, methodical breaths, you remind yourself. Deep and methodical. And oh so deep. You wrench your thoughts from this enticing path, lifting gaze to meet his. Your eyes seek permission, finding his half-lidded stare heavy with want.

Your palm, warm and inviting, glides along his length with exquisite slowness. The motion elicits a shudder that ripples through his hips, a breath catching in his throat like a trapped butterfly. His head falls back, unveiling the elegant lines of his neck.

Emboldened, you repeat the caress, this time allowing your grip to ascend until it reaches the pinnacle. There, with deliberate tenderness, you gather the pre-cum with a slight swipe. The touch brings a cluster of stuttered gasps and half-formed words. His body, as if magnetised, curls towards you, hands grasping the edges of the bench, white-knuckled, anchoring himself.

Your name escapes his lips in a plaintive groan, lust renewing his voice with a gravelly quality.

Responding to his unspoken plea, you stretch upward, capturing his mouth with yours. A reward. A prelude. Your lips, soft yet insistent, trail a path down to his chin, then along the sharp line of his jaw. He tilts his head back, an offering, granting you unimpeded access to the column of his neck. You accept the invitation eagerly, pressing a kiss to his bobbing Adam's apple, and leaving a trail of lilac.

Your hand torments him with a slow ride down, grip tightening incrementally with each kiss. But there's a yearning for more, craving something more substantial. Not that this isn't intoxicating—the pulsing in your core is evidence enough.

The moment a more desperate whine unfurls from his lips, a ribbon of pure need, drawing you in. It's the tipping point. As if thanking him for the sinful sound, your lips abandon the canvas of his neck, attention now wholly focused on his full, flushed hardness.

You level with the sight of his arousal, standing eager, tip glistening. Your breath ghosts over his sensitive skin, eliciting a shudder that courses through his entire body. You hear the complaint of squeezed leather beneath his grip.

“Show me how you like it,” you breathe, letting the little puffs of air tickle at his reddened shaft.

Seemingly overwhelmed, he remains answerless, eyes resting on your blushed mouth. “You’re beautiful,” he murmurs, as if reciting an undeniable truth, akin to the blue of the sky or the firmness of his length. His thumb traces the contours of your mouth with gossamer lightness. “Indulge as you please,”

At that, you smile, gently guiding his hand away and pressing a kiss tender on his knuckles. And with a final, heated glance up at his face—flushed with want, eyes dark with need—you lower your head, lips parting.

With a delicate grace, you envelop him, your lips forming a perfect crescent around his crown. Slowly, deliberately, you welcome him into the warmth of your mouth, one hand gliding to his base with tender precision. The other, seeking purchase, finds his chest, gently urging him backward to grant you greater freedom of movement.

He yields without resistance, acquiescence punctuated by a cascade of desperate, breathy whimpers as he reclines against the piano. The instrument protests beneath his bones, dissonant notes plunking out objections at the sin unfolding before it.

You savour him—heady salt and warmth. His velvet glides across your palette, your lips tightening in counterpoint. Your tongue laps and flattens against him in a rhythm that plucks a brief grunt from him. Curiosity compelling you, you lift your gaze to meet his. In that fleeting moment, his eyebrows arch—whether at the feeling or the sight, you prefer the idea of the latter—a wordless expression of awe at the vision before him.

This silent exchange ignites a fervour in you. You increase your tempo, sound of saliva blending seamlessly with his escalating pants. His voice, once controlled, now tumbles in a torrent of incoherent, keening pleas. His fingers now tangle gently in your hair, curling and uncurling in unconscious rhythm. When you dare to take him deeper, his grip tightens ever so slightly.

A deep groan reverberates from the depths of your throat, setting off a cascade of reactions that ripple through both your bodies. The raw sound triggers an involuntary response in him; his hips stutter and twitch forward with barely restrained urgency, cock brushing dangerously far back in your throat.

This sudden intrusion causes your body to react instinctively. Your grip on him tightens, fingers digging into the soft flesh of his thighs, pliant tongue pressing fully against him, cheeks hollowing with increased suction.

The sensation brings tears pricking at the corners of your eyes, threatening to spill over. Yet, you hold them back, your focus entirely consumed by the incoherent, mangled words tumbling from Viktor's lips. His loss of composure only serves to fuel you, ushering more strangled moans from you.

With a deliberate leisure, you pull him out of your mouth, slight, wet ‘pop' punctuating the action. A grin plays across your lips as you lick them slowly, savouring his taste and the way his eyes track the movement of your tongue.

Leaning back in with renewed purpose, you flatten your tongue against the sensitive underside of his length. You drag it upwards, feeling every ridge and vein. As you reach the tip, you linger at the frenulum, that exquisitely sensitive spot just beneath the head. Your tongue dances there, teasing and tantalising, while your hand presses firmly against his abdomen, pushing him back slightly, maintaining control.

This calculated move elicits a pleased hum from him, a sound that vibrates through his body and into yours. Encouraged by his response, you repeat the movement, each pass of your tongue a perfect mirror of the last, building a rhythm that teeters on the edge between pleasure and sweet torment.

You revel—the choked desperation emanating from the back of his throat, the frantic rise and fall of his chest—tempestuous sea. His jaw, slack, burns into your imagination, conjuring tantalising visions of how it might feel nestled between your trembling thighs. Pure masterpiece before you.

A thought dances through your mind: how differently might he approach his little entanglements if it were you sprawled across his desk instead of the mundane paperwork? The notion trails a delicious shiver down you.

The tip of your tongue traces feather-light around his sensitive crown. Slowly, teasingly, you envelop his tip between your lips. Tongue, emboldened, finds its way back to the frenulum and lingers there. Your hands continue to glide in smooth, quickened motions, descending and rising fluidly. His breaths grow increasingly laboured as you continue, his hips jutting and twitching. You apply gentle pressure, guiding him downward.

With a filthy cry that escapes him, you feel the hot release at the roof of your mouth. Encouraging him further, you draw him deeper, welcoming the spill into your throat with a rough hum. His voice breaks as he calls out your name between ragged gasps. It sounds almost like prayer.

Further sinful whines fall out of him as you continue to swallow and lap him from inside.

As you feel his tension finally easing, you slowly withdraw, your tongue tracing the pearlescent spill. His sharp, staccato breaths punctuate the silence, and he brings his hand to your chin, lifting your attention to him.

You smile, swallowing, though proving futile, his release unrelentingly coating the back of your throat.

“Will I get to demonstrate?” he breathes, voice hoarse.

He smirks. The fucker.

You shake your head. “Not tonight. Tonight’s my repentance,”
