The Demon King's Doll...

The air in the Infinity Castle was always still, smelling of aged wood and the faint, metallic tang of something ancient. For you, this place was a beautiful, terrifying maze—a playground built of shadows where the laws of gravity were merely suggestions.

You clutched the hem of your pale pink kimono, your breath coming in small, soft puffs. You were small, a gentle soul caught in a world of monsters, and today, you were feeling particularly playful—or perhaps just desperate to see a crack in the cold porcelain mask of the man who owned this realm.

"You can't catch me, Muzan-sama!" you chirped, your voice high and sweet, echoing through the shifting corridors.

Behind you, the rhythmic thud of his dress shoes on the polished wood was slow and deliberate. Muzan didn't run. He didn't need to. He walked with the predatory grace of a king who knew that time was entirely on his side.

"You are making a great deal of noise for someone so small," he said, his voice a deep, silken vibration that made your skin prickle with a mix of fear and adoration.

You squealed softly and took off, your white tabi socks sliding slightly on the floor. You rounded a corner, your eyes wide and bright, expecting to find a long hallway to lose yourself in. But just as your foot hit the threshold, a haunting, singular note of a biwa rang out.

Twanng.

The world tilted. The wall you were heading toward dissolved into a ceiling, and the floor slid away. You stumbled, disoriented, only to find yourself running straight toward the very man you were fleeing. Muzan stood just a few yards away, his crimson eyes glowing with a dark, amused embers.

"Oh!" You gasped, skidding to a stop, your heart hammering against your ribs like a trapped bird. You spun on your heel, your childish instincts taking over, and dashed in the opposite direction. "Nakime-san, that’s cheating!"

From her hidden perch, the Upper Moon remained silent, but the castle groaned in response. Every time you thought you had found an exit, every time you reached a dead end and prepared to hide in a corner, the biwa would strike again. Rooms flipped. Shōji doors slid open to reveal pits of endless darkness or upside-down staircases.

No matter which way you turned, the castle conspired to deliver you back to him.

You were getting tired, your legs feeling heavy under the weight of your silk layers. You were soft and unaccustomed to such exertion, your quiet nature usually keeping you tucked away in the library or the gardens. Your vision blurred slightly with exhaustion, and as you attempted to make one final, desperate turn away from the approaching shadow of the Demon King, your foot caught on the long, decorative hem of your kimono.

"Ah—!"

The floor beneath you vanished just as you began to tip forward. You braced for a hard impact, your eyes squeezing shut in terror. But Nakime was precise. With one final, resonating note, the room shifted a full ninety degrees.

Instead of hitting the floor, you fell into something firm, cold, and impossibly strong.

The scent of expensive cologne and old power enveloped you. You opened one eye, then the other, to find yourself cradled against Muzan’s chest. His arms were locked securely around your waist and shoulders, holding you as if you were a fragile glass doll he had no intention of breaking.

"Have you finished your exercise?" he asked, peering down at you. His gaze was intense, enough to make a lesser being wither, but for you, there was a trace of terrifying tenderness.

"I... I almost had you," you whispered, your voice trembling. You were scared of him, yes—everyone was—but you were also drawn to him like a moth to a funeral pyre. You reached out, your small, gentle hand resting timidly against his lapel.

Muzan tilted his head, watching the way your chest heaved with exertion. You were so quiet, so innocent, a flicker of light in his eternal darkness. It pleased him to see you breathless because of him.

"You had nowhere to go," he murmured, leaning down until his cold breath brushed your ear. "Every inch of this fortress obeys me. Just as you do."

He didn't wait for an answer. He tilted your chin up with a pale finger, forcing you to meet that crimson stare. Then, he leaned in, pressing his lips to yours. The kiss wasn't soft; it was possessive and demanding, tasting of power and ancient hunger. You let out a tiny, muffled whimper, your fingers curling into his suit jacket as you melted against him.

When he pulled back, he didn't let go. He simply tucked your head under his chin, his hand stroking your hair with a gentleness that was perhaps his greatest cruelty.

"Stay still now," he commanded softly. "I have you."

Kibutsuji Muzan: Reincarnation

You're back..

Genre: Romance // Muzan x oiran!reader

⚠️: prostitute!reader, suggestive, kidnapping, not fully consensual

A/N: My first non-bsd fanfic !! I'm super happy about it, I read about an oiran and the differences in social classes at 12AM, it was like reviewing for my history class again. It was a lot of late-night reading so if there's misinformation please inform me immediately !!

INSPO: pinejayy

It was a well-lit and busy night, as it always was in the entertainment district. Little did everybody know the demon king—Kibutsuji Muzan was in their midst, walking along the streets, blending in with the loud crowd.

A procession was about to start, all eyes would be on the oiran—dragging her geta on the ground as she walked. The oiran on this particular night was none other than, you. Your scent was immediately picked up by Muzan. It was the same scent he had grown to love, from the person he had lost to time.

His interest was piqued the moment he picked up your scent. His gaze traveled far, trying to find the source of the scent. His gaze then landed on you, he watched you as you walked with such grace, you were as beautiful as the day he lost you.

Muzan lost you through the inevitable disease called time. You weren't willing to become a demon—instead, you promised him that you would find eachother in each lifetime and it will all end the same, with you in his arms.

You were given the name 'Minori' by the oiran who took you in as a child, starving in the unforgiving world of class and power. As an oiran you were known to be quite finicky. Although an oiran did have the right to choose who they would lay with, you were known for having not slept with anyone ever since you rose to your rank. Many men tried wooing you with their "looks" and "charm" but in the end you deem none of the worthy.

You were intelligent, beautiful, and skilled in various languages and arts. You were also a dear friend of Koinatsu, one of the most revered oiran in the Yoshiwara District. Muzan had heard about Minori before, from mundane gossip to papers of advertisement. He just didn't expect it to actually be you.

After seeing you walk, he spoke to Daki. He had released an order to his demons that you weren't allowed to be killed—instead, you had to be protected. Anyone who had protested against Muzan's order was immediately killed, without another word from their lifeless lips.

You had just gone back from the procession, you were quietly fixing up in your room, filling it with your presence. It was neither sweet nor destructive, it was just you. You were sitting in front of the mirror, fixing your hair until you saw a man appear behind you—you immediately stood up and looked back in fear.

Suddenly the room went dark, you couldn't see a thing. You then felt an eerie presence behind you—it was Muzan. He gently grabbed you from behind, by the waist and pulled you closer to him. "You're back.." he whispered in your ear.

It was strange, the man's touch was cold and his breath wasn't even slightly warm. Your body tensed up, "b- back..?." you nervously asked "Y/N.. I thought I'd never see you again.." he mumbled softly while one hand was secured on your waist, preventing further problems and the other hand lifting your chin to one side, granting him access to your neck.

'Y/N? Who was he talking about? I don't even know anyone named Y/N, maybe this was a new thing with men, maybe roleplay is quite popular nowadays, is this just a drunkard that wandered in my room?!' were the thoughts that ran into your head. You were too afraid to move, you didn't know what wrath would be brought down on you if you disobey.

Chomp he bit your neck, his fangs sunk into your neck, blood trickled down your skin, staining your carefully crafted kimono. You felt a sharp pain in your neck, you felt the blood trickling down your skin as well. He removed his teeth from your skin, letting the blood flow down.

Tears rolled down your cheeks as he stopped biting you, he turned you to him and wiped your tears away with his thumbs, a soft smile could be seen on his face. "Oh Y/N.. you used to love my bites.." he spoke with a sweet tone. You reached up for his hands "Who are you.. please stop.." You muttered, your fear was clear, you were trembling slightly as you held the back of his hands tightly. This made him angry, his grasp on you tightened and the soft smile on his face was replaced by an angry scowl.

He wasn't letting you go this time. You were going to live with him forever, he couldn't abide by your wishes. He needed you by his side, he wasn't going to play by the rules set by time and destiny.

You whimpered softly as he tightened his grip. His hands travelled back to your waist, pulling you in. You haven't fully grasped the events of the night. It was all too much.. how could he bite you like that? Who was Y/N? You looked at him through your tear-filled eyes and held onto his chest. "P- please.." you mumbled.

Muzan wasn't going to listen to reason, he let you have some of his blood to ensure that you'd stay with him forever. You were now a demon at his mercy. Although you didn't suffer the same curse the other demons did. Muzan wanted to hear you say his name, after not hearing it for centuries, he needed to hear it now.

You grasped his arms tightly as you felt yourself transform from a human to a demon. You felt your fangs and your desire for blood growing. You were still clearly competent but your body grew weaker due to the high concentration of his blood. Muzan picked you up, making sure you wouldn't be able to escape. "It doesn't matter if you don't remember me, in time you'll learn to love me again." He spoke with a cold tone. He then disappeared into the night sky with you in his arms.

Muzan Kibutsuji Yandere Headcanons

Warnings: Sadism, kidnapping, yandere themes

➼ You're in deep shit if he goes yandere for you.

➼ Of course, at first he's just fascinated by you. Your beauty is compelling to him, but even more compelling to him is the fact that someone as beautiful as you decided to become a demon slayer and annihilate demons. Slowly, his fascination with you becomes an obsession as he sends even more demons to find you after the last demons he sent failed to. 

➼ Once he finds you, his first plan is to cage you in the Infinity Castle. He's probably going to let you stay as a human for some time as he likes how powerful he is compared to you. Once he does find you, he's going to order Nakime to get more information from you (by stalking you) along with the location of the corps.

➼ He's felt immense potential in you since the first moment he saw you. You looked sort of familiar like he'd seen you before. It would be a mistake for him to let you let go from his claws.

➼ Surprisingly, he doesn't hate the fact that you're a demon slayer. It's actually amusing to him to see someone like you hunt down demons. But he does hate the fact that you show so much compassion for humans. In his eyes, they're pathetic beings who don't deserve you.

➼ He's a mix between a possessive and a sadistic yandere. Red flag? EVERYTHING. He's probably going to enjoy mentally torturing you by trapping you within the Infinity Castle. Whenever demons are in a fight with you, he carefully monitors them and might even give them instructions to hurt you as he's fascinated by you and is curious how you'd react. He loves observing you, that's for sure.

➼ Oh, he's never going to let you go once he's gotten a hold of you. He's going to study and solve you like a mathematics equation.

🍓◌𓆩☽❀☾𓆪◌

Summary: You just want your husband to show you love and affection

Warning: Smut, Breeding kink, Overstimulation, Oral sex M!Receiving, Shower sex, sub!Muzan Dom!reader, slight orgasm denial, your deranged A/N: I don't usually post nsfw nor do I take nsfw request, then why did I make this? simple, I just really like Muzan. Also I'm still taking non f!reader request, I just made this because I want to. This is my first nsfw post so that’s why it’s ass

You have been married to Muzan for approximately a year now. Despite his sickness, cold demeanor, and occasional outbursts of yelling, you held onto the hope that your marriage would take a turn for the better.

You craved a family with Muzan, hoped to have living prof of your love with a child. However, intimacy between you is scarce having only being intimate on one occasion, your wedding night. You've grown increasingly frustrated with the fact of love in your relationship. Despite your attempts to reignite the spark and deepen your connection, every effort was met with resistance from Muzan, who has even refrained from simple acts of affection like embracing you.

Now you are desperate, his health has been declining and you've still have yet to bare his child. At this point You aren't even concerned if he loves you, you just want him, his body and his child. Tonight you would take matters into your own hands.

＊✿❀❀✿＊

Your movements are filled with a mix of urgency and longing as you hurriedly remove your clothing. You've waited far too long and now, finally, your deepest wishes are on the verge of becoming reality.

You quickly step into the bath, and you see Muzan sitting there, waiting for you. Soap bottle's were places neatly on the ledge beside him. "Y/n what are you waiting for? come in" Startled by being snapped out of your thoughts, your cheeks heat up in embarrassment and you hurriedly make your way towards him.

The water feels unbearably warm, intensifying your nervousness. As you reach for the bottles of soap, your hands tremble, causing you to stumble. Muzan's gaze grows increasingly irritated, and in a fit of frustration, he abruptly grasps your arms. His eyes bore into yours, their coldness piercing your soul. The sound of your name escaping his lips sends a jolt of mixed emotions through your heart. "Just pick it up, Y/n," he says curtly, his voice devoid of warmth. You find yourself whispering an apology, though you doubt he even hears it.

You squirt some soap onto your hands. Gently you grab muzans hair and brush your fingers through his hair, making sure to get the soap all in his hair. Picking up a bowl you pour water on him, making sure you get out all of the soap. One last time you run your fingers through his hair seeing if there is any soap left, there wasn’t any.

Muzan rises from the water and takes a seat on the bath ledge, he looks like a god. However, beneath his stunning exterior, you are reminded of his unpleasant nature, to say the least. You reach for another bottle of soap you assist Muzan in cleaning his skin. Gently and attentively, you apply the soap, rubbing it onto his skin with care. Your hands gaze over his thin arms, moving down to his chest and then lower down to his crotch.

You slowly sit into the way the water, you grab his shaft. A jolt of surprise evident on his face and his cock twitches in your palm. "What are you doing, Y/n?!" Muzan's gaze locks onto you, his eyes widening in astonishment. Your current actions seem to deviate from your usual character, leaving him perplexed. "I'm cleaning you up," you assert confidently, your voice clear and resolute. Your statement carries a sense of purpose and determination, leaving no room for doubt in your intentions. Lowering down to his shaft you lovingly kiss the head, a free hand moves to play with his balls. This causes him to cover his mouth and whimpers -he’s sensitive- you look up at him, Tears begin to well up in Muzan's eyes, on the brink of spilling over.

Again you kiss the head of his cock, immediately after you give a couple generous licks to his pretty pink tip. His cock becomes hard on your tongue, which makes the pool in-between your legs grow. Generously your free hand plays with his heavy balls. Your mouth is skillfully working on pleasuring him while he's near tear filled and struggling to keep his composure, he's failing miserably.

Putting his tip fully into your mouth you slowly lower your self down to his base, he moans as he feels his shaft hit the back of your throat. Tears of pure joy and endearment develop in your eyes, you're thrilled that he's enjoying this.

He places a hand on the back of your neck, encouraging you to continue. straight away you bob your head up and down, you try not to gag on his cock has it hits the back of your throat. Muzan wraps his legs and arms around your head, he's struggling under the sheer pleasure that your lovingly providing him. "Oh-oh God!" he chokes out a sob, in response you fasten or pace. A ring of drool and pre-cum form around your puckered lips, this giving you the sign that he will be cumming soon.

“F-fuck…I’m close!” He was about to release into your mouth but you pull away before he can. His pretty pink cock twitches from the lack of release. Muzan gazes fixates on you while tears fall down his flushed cheeks. The look in his eyes is a look of complete and utter betrayal. Usually such a look was stir up concern in you but this time, his tears are from the deep yearning of wanting a release. “Don’t worry my love, you’ll get to cum soon” you smile ever so softly at him, soon he’ll fill you with his love

You arise from your original sitting position and wipe away the pre-cum from your chin. You seat yourself onto his lap cautious of the amount of weight you put on him. Gripping his cock you line it up to your neglected soaking hole. Straining longly into his eyes all you say is “soon baby, soon”. Finally you lower yourself down onto his perfect member. You both let out a moan how much louder than yours. Your walls squeezes trying to already squeeze him of all of his worth. Your mind is a fog all you can think about is his cock filling your womb up to the brim, telling you how much he’s gonna love seeing you full with his seed.

You slam your lips onto his, shoving your tongue into his mouth while wrapping your arms around his neck. Surprisingly Muzan responds by kissing back, he's a lousy kisser but just the fact that he is returning affection to you makes you melt into him.

He places a hand on your ass and squeezes it, the other deciding to rest on your hip. It's not long before you start to lift your hips, trying to start a rhythm. Soon you find the perfect rhythm your moves are now bold as you start quacking up speed. Muzan throws his back it's just all too overwhelming for him. He struggles to keep his body up as he already feels himself weakening from the pleasure. You feel completely enveloped in his love as you hear him moan and beg for you.

"Aah-Y/n please!" he yells while fat hot tears pour down his puffy cheeks, you hips stop moving abruptly and you lift yourself off of him. A lovely string of pearls connect your dripping pussy to his shaft, your walls try to clutch on his cock but only clutches onto hair. "Please what? use your words my love" your voice is filled with a mixture of longing and determination. You yearn for Muzan to say those words you've been craving for far too long. You'll continue to deny him just how he knowingly denied you until you hear him say it. "p-please..." he has long pause as he struggles to catch his breath "please...let me fuck a baby into you..".

That's all he had to say in order for you to promptly snap your hips back down and riding him like your life depended on it. You didn't even bother to try and hit your sweet spots, just knowing that soon he'll release into you was already sending jolts of unimaginable pleasure to your core. Muzan then suddenly grips your hips with all of his strength and bucks his hips up into you causing you let out a loud moan, he had hit your sweet spot. "fuck! I'm cumming!" Is all that he said before you and him both came. Keeping his promise he spilled hot sticky ropes of cum into your womb.

Tears stream down your cheeks as the realization sinks in—you are on the verge of having the family you have always yearned for. The journey may have been long and challenging, but now it is finally coming to fruition. Determined not to burden your husband with your emotions, you swiftly wipe away the tears that cascade down your face. You want to ensure that he does not worry, focusing instead on the joyous prospect that lies ahead.

Muzan, utterly exhausted, lays down on the floor. The shadows of unconsciousness gradually creeps up on him as he's on the edge of passing out. He's shaken up by the sudden action of you starting to ride him again "I'm sorry, I know its not exactly sexy to do the same position again but it's the only one we can do with your current state!" You gaze down at him, your eyes filled with an intense and unhealthy devotion that borders on obsession. A deranged expression manifests on your face, reflecting the depths of your distorted love for him.

Muzan is completely worn out and drained, so it doesn't take much for him to already be a blubbering mess under you. "goddamn you woman! are you trying to drain me?!" all you do is giggle in response. Muzan's eyes widen with the dawning realization that this will not be the last round, he just continues to lay down and take it.

placing his hand on your tummy as you continue to ride him all you say is "let's shoot for twins"
