His eyes gleam with the soft glow of the light over your head. Behind him are massive windows that show the cityscape of modern-day Tokyo, the twinkling neon lights like stars you could touch. You’d always dreamed of coming into this building, but never had you thought you’d be sitting here – across from the biggest name in Japan and quite frankly, the world. 

It made your whole body buzz with child-like excitement. As an interviewer, you had to scrape by on nothing until the right opportunities presented themselves. When your boss specifically asked for you to hold the in-house interview, you knew this was your big break.

“So, Mr.Kibutsuji, the paparazzi have difficulty finding you.” He smirks, leaning back against the large couch he sat on across from you – only a table separating you from the mysterious man. 

He peers off to the side, studying a magnificent piece of artwork on his wall. “It’s because I don’t want them to.” He blinks the crimson of his eyes back on your sweet face. His answer is matter-of-fact and if he went on like this, the interview would surely be a bust. 

You laugh politely, looking down at your approved list of questions. The thumping in your chest tells you that this isn’t a good idea, but you set it firmly down on the table in front of you, grinning up at the worldwide star. “Is that so? Mind if I ask you some questions off the record?” You scoot to the edge of your seat, watching as the ravenette perks up at your question. 

It intrigued him. He asked for an inexperienced rookie to simply ask him the questions on the sheet and not pry into his carefully secluded life. Yet, here you were, the questionnaire already on the table with a perky smile on your lips. Muzan feels the corner of his mouth quirk into a grin. He blows out a breath, gesturing in a circular motion freely with one of his hands still strung across the back of the couch. “You’re going to no matter what, so why not give you what you want?” He hums, distracted by the way your knees part ever so slightly to position yourself more comfortably on his furniture. A jolt of electricity pulses through him, shocking him into meeting your intense gaze. 

Muzan Kibutsuji had spent a millennium disregarding the way women made him feel. Never had one interested him enough to break focus on his goals. Sex was something to break the silence of failure, not anything to spend his time on. But you… you were a carefully crafted complexity of sexual frustration. 

He runs his tongue along the inside of his mouth, suddenly parched for a taste of anything. The ringing of your laughter snaps him out of his daze momentarily. “Yes well, I’m known to be pushy when I want something.” 

Me too, Muzan thought. You open your mouth as if you’re about to start, but then you pause, screwing your lips shut. “Before we start, do you mind if we get something to drink? I’m dry as a mouse over here.” You mess with your fingers nervously wondering if that was the correct thing to ask. 

Muzan lifts a brow. “I was unaware mice got dry.” Nevertheless, he lifts himself off the couch. “But that is acceptable. If you’ll follow me to the kitchen?” He walks around the side of the table, offering you a hand. You gulp, tentatively putting your hand in his. 

He guides you to the kitchen island, pulling out a seat for you. You thank him with a nod of your head, gratefully climbing onto the stool. Setting down the tape recorder on the counter, you glance around the silver and white area. The kitchen is just as dim as the living room, the lack of light only making the slight brush of Muzan’s arm against your back send shivers down your spine. “I’ve always wanted to come into this building,” you blurt before cursing lightly under your breath. “Well, er, I mean to say… thank you. I’m grateful for this experience.” You ramble to cover up the embarrassing fact that you basically just admitted you’re poor. Muzan chuckles lowly, the sound rumbling around your head as he sets two wine glasses on the marble countertop. 

“Château Lafite 1869?” He lifts an expensive-looking bottle in the air. You catch a glimpse of the label, a detailed depiction of some sort of mansion with trees around it. He pours the red liquid into the cups, the noise filling the silence. When he’s done he picks both glasses up by the stem of their neck, setting one down in front of you. The aroma is divine. “My turn for a question.” Muzan leans against the lip of the island, staring into the pool of wine in his glass. He swirls it around, glancing up at you. “Just how thankful are you?” He questions.

You smile, bringing the glass to your lips and letting a bit of the wine fill your mouth. Muzan watches you with swept attention. The flavor is complex but you catch a hint of spiciness hit the back of your throat. You set the wine glass down, trying to think of a response. “You’ve done it all wrong,” Muzan’s brows are furrowed as he stalks toward you. He grabs hold of the glass, dipping his finger into it. Your eyes widen when he drags the pad of his finger along your lips. Subconsciously you part your lips, breathing shakily as you daringly dart your tongue out. 

His eyes light up like an inferno, capturing your chin his nostrils flare. “So thankful I’d do anything.” You sputter out against the hard grasp he has on your chin. He rolls his lips under his teeth, huffing out a laugh. 

His free hand grabs your ass, spinning you around on the stool so you’re straddling him. “Is that so darlin’?” He flings your head to the side, the motion making you fall against the back of the counter. “You figure you don’t have what it takes to succeed so you’ll suck my cock, is that it?” He mummers, dragging the back of his hand down your exposed neck. 

Your body heats as you narrow your eyes. “No, that not-” You shut your mouth when his gaze locks onto yours. 

His hands find their way to your thighs, pressing them apart and savoring how your skirt rids up the plush skin. “Oh come on, you even wore a skirt. You knew what you were doing. Off the record? Please, that’s so they won’t hear you screaming my name back at the office,” He squeezes the skin of your thigh, causing you to hiss out in pain. “But I can fix that.” He smirks, running his fingers over the bruised skin. 

You pant heavily as you watch him devour you with his gaze. “We,” You gasp as he somehow rips your shirt to shreds. You regard the fabric of the once nice shirt that covered your torso now falling to the floor – parts of it still clinging to your body. 

The man in front of you runs a hand through his hair, grinning at the sight before him. “That’s more like it,” He hums, plucking the clasp on your back apart, letting your bra slide down your shoulders. “By all means, if you were about to mention the interview, continue asking me questions.” He pushes further between your thighs, flicking your nipple. You groan, the sensitive bud growing stiff. Muzan scoffs. “Though I doubt you’ll be able to.” 

He gathers liquid on two of his fingers, shoving them into your mouth. You squeak at the rough plunge, but your tongue sucks around the earthy tones of the wine. “Hmm, I think I’d rather like the look of you on my counter. Up you go.” You’re being lifted suddenly onto the island. Your skirt is around your hips, the cold of the counter on your ass making you squirm around. “Spread your legs.” He instructs, inspecting how you shyly part your legs, revealing your naked pussy. He scoffs again, tilting his head with a smug expression. 

You turn your cheek against the counter, flushing with embarrassment. “Don’t laugh,” You whine, pouting as the heat of his hand traverses up your leg. 

Muzan’s fingers graze the area of your inner thigh with lecherous intent. “Don’t be embarrassed, I don’t blame you for wanting to fuck me.” Your eyes flutter shut as he draws circles around your mound, playing with your emotions like they were an appetizer. “Besides, I’m going to fuck you real good,” His fingers slide into your pussy, exploring the new area. You groan, squeezing your eyes shut at the sensation. “Hmph, already so wet. You sure did come hot and slick.” He muses, using his thumb to press into your swollen clit. 

A hand clamps over your mouth as you writhe against his ministrations. “Fuck, sir-” Muzan shoves his fingers deeper, aggressively reaching for your throat. His massive hand wraps around the span of your throat, squeezing your windpipes. 

“Call me that again,” He commands, the fire in his eyes now dark and blown out. You huff out tiny breaths, nodding your head. He removes his hand slowly dragging it down your navel, before gripping the side of your thigh. His fingers curl deeper inside of you and your eyes widen. 

A panted moan falls from your lips as he continues. “Just like that, yes, please sir,” He smirks, pushing down on your clit. A yelp echoes around the kitchen at the sudden pressure. 

Muzan lavishes in the way your throat has a red ring around it, marks from him spotting your body in a gorgeous display of possession. “Such a good girl for me,” He growls, slipping his fingers into his mouth to taste your arousal. You watch him with the swell of desire wrapping its claws into your core. “What a wonderful pairing with the Rothschild.” He mutters, grabbing one of the glasses and swigging the liquid into his mouth. 

A devious grin paints his face as he lowers the glass, meeting your gaze. He tips the glass against your stomach, letting the dark red wine trickle tributaries down your greedy cunt. “Don’t worry, I’ll clean you up.” Muzan’s mouth is hungrily lapping at your folds, delighted noises streaming from him as he savors the taste. “Intoxicating,” He huffs, swirling his tongue around your clit before sucking hard on the sensitive area. 

Your throat is sore from the way whimpering moans string together shakily. Your stomach is pulsing with a sensation unlike anything you’ve ever experienced. If he didn’t stop, you felt like you might explode. “M-Muzan,” You begin, huffing out his name. He hums against your folds but doesn’t stop. “Ah, ah,” You start to shake against him, the ravenette pumping his fingers inside of you while licking your clit savagely. “F-ck, m’gonna, hngh haaa ahhh,” 

Muzan’s mouth curls deliciously as your back arches off the counter. Then, with a few bucks of your hips, wetness sprays from your pussy. You shiver as the squirting continues, your body twitching with untouched pleasure. Breathing seems impossible as Muzan licks his lips. “What a wonderful show, but unfortunately we’re still not done.” He pulls you down the counter, lining the apex of your thighs against the bulge in his pants. 

Your eyes widen, he can’t be serious. You were barely conscious after whatever just happened. Did he expect you to go all night? What was this man made of? He frees his cock, the tip slapping against your sensitive cunt. You squeeze your eyes shut. How is it that big? It didn’t feel that big when it was pressed against your thigh. Holy shit. Was he going to put that thing in you? “You’re gonna take all of it,” he begins, pushing the head against your slick. You blink open your eyes, pushing yourself up on your elbows to observe his length disappear inside. A strained hiss slips past your lips, Muzan rolling his hips into yours. “Fuck, your pussy should do all our interviews from now on, damn,” He groans, digging the nails of his fingers into your flesh. “You’re gobbling me up,” He meets your gaze, a growing rhythm snapping his cock into you. You throw your head back, moaning his name like it was a prayer. He felt like he’d been doing this a lot longer than any person you’d ever been with. 

Muzan pushes his thick length further, humming in satisfaction as your walls flutter around him. You couldn’t think, all rational thought was flung out of his huge windows the moment he pulled out that bottle of wine. “Ngh, f’so good, mmmngah,” 

He finds it delightful the way your pussy grabs his cock like it wants more. You had a magnificently fucked out face, your eyes rolled back in your head as your mouth hung open. With each compression of your chest, a hoarse whine pushes back out. Frankly, it was music to his ears. So he grabs the recorder you’d set down earlier, pressing the little red button. He grins as the timer starts ticking again. “Such a good slut for me,” He muses, slapping his balls against your ass as he pounds your pretty pussy. “Your cunt is lovin’ this,” He thrusts deeper and deeper until all you can manage is mewling little noises. 

As you grow closer to your second climax, you rest your back on the counter, enjoying the way the cool stone feels against your sweaty back. “Come on darlin’, is that all you got? This why you wanted me off the record? To fuck you silent?” He chuckles, glancing at the recorder next to your trembling thighs. “What a sneaky vixen, is this how you treat all your clients mmm? Offering your pretty pussy with fluttering doe eyes?” He groans, nearing his own wash of pleasure. “Well, on the record, you belong to me now. Got it? You’re my whore whenever I want.” 

His thrusts grow rapid, burrowing his cock inside of you like his life depended on it. With this life of failure, he’d finally found something worth trying to succeed for. Muzan could feel the old vigor seeping into his veins. He pulls out, pumping his cock until a strangled moan escapes his lips, cum landing on your breasts. He’s a panting mess as he takes in what he’s done to you. A puddle of Rothschild and your arousal soaks the wood of the floor. He picks up the tape recorder, bringing it to his lips. “You hear that, Hashira scum? I made your bitch scream my name.”
