W/C: 2.5k+

In the time you’d been together, he had yet to smell your blood, it was hard enough to be placed in the situation when he always made sure you weren’t injured whenever he was around, and as such a high-ranking demon, he lacked the privilege to spend as much time with you as wanted, so the timings hadn’t lined properly for him to be present during your period either, but when they finally did without you being aware of your unique type of blood, to say the least, neither of you were ready.

Muzan Kibutsuji

Takes full advantage of the situation.

Has to take a step back to steady himself the first time he smells you.

Is initially worried you’re injured at first.

Plays his cards right and shows initial concern despite your body doing a normal biological function.

Is more physically affectionate to get you to lower your guard even more.

Gets you to admit out loud that you’re in physical pain.

Suggests helping you ease the pain.

Had never buried his face between your legs before.

Was actually kind of sexist about it and would’ve felt inferior if he placed your legs on either side of his head, because why would the demon king do that?

Still tried to refuse but smelling your marechi blood didn’t help.

Having a monthly supply of marechi blood sounded tempting enough.

So he suggests easing your pain.

Surprises you by finally spreading your legs after laying between them.

Keeps you around him for the entirety of the week.

Takes you wherever he needs to go to keep you close.

But never near any demons.

If necessary, he has Kokushibo watch over you.

Doesn’t necessarily refuse to not have you in his presence.

But refuses to leave you alone and unguarded for other demons to try and eat you.

Knows that Kokushibo won’t even consider so much as laying a finger at you.

Still refuses to get on his knees for you.

You always have to lay down for him.

Forbids you from wearing anything under your kimono to have easier access.

Instantly smells whenever your blood’s about to stain the expensive fabric of your kimono.

Licks you clean every time he smells you starting to bleed.

Which is multiple times throughout the day.

As soon as you express being relieved from the pain, he uses it as an excuse.

Prefers you thinking he genuinely and solely wants to care for his favorite human rather than admitting that he needs to feed like any living creature.

Because he refuses to so much as get on his knees for you, he obviously even more so refuses to have you sit on his face.

Not even hover.

If you ever suggest it, he’ll give you the meanest side eye and refuse to speak to you for days.

Still will not eat you out outside of your period.

The moans entering Muzan’s ears easily sounded different than usual, similar to the first time he had you take his heavy cock in your lower area, where he was currently lapping at you for the first time with half lidded eyes in a relaxed expression while laying on his stomach for you, hands on either of your thighs which obediently remained spread open for him with ease due to how the rest of your body had fallen limp upon the first lick.

He had his doubts at first, but he had to admit, it’s awfully convenient to have a marechi lover who was so willing to hike up the expensive kimono and spread open the legs beneath it to allow him to feed rather than having to go through the trouble of going out of his way for people to eat. A louder moan fills the room as he dips his tongue inside your sensitive opening after having licked clean your labia.

A shaky hand reaches for his hair in attempt to pull him closer only to be pushed away rather gently by the man at your thighs. Normally, he would’ve slapped away the hand because despite actually bearing affection for you, how dare you try to command him in any way, however, he supposes the meal you’re offering him is enough for him to turn a blind eye to your insolence… once.

Kokushibo

Very concerned for your health when he finds out.

Initially thinks you’re injured upon smelling your blood for the first time.

Takes a second (one too long in his opinion) to regain his composure after the scent of your blood makes him feel dizzy.

The opposite of Muzan.

Has eaten you out before.

And doesn’t mind doing it.

Genuinely suggests relieving your pain for your benefit.

Takes great pride in taking care of you.

Hardly even thinks of you as a source of food with how much he prioritizes easing your pain.

But does acknowledge that you’re keeping him well fed.

Another one that keeps you with him every time you’re on your period (they all do).

Doesn’t think much about if he likes or not getting on his knees for you.

But knows your height differences would make it a bit uncomfortable.

And prefers you lay down for your own comfort.

Will also eat you out whenever he smells blood on the way.

Enjoys doing so but does it mainly for your safety as to not attract any demons.

Doesn’t just drink your blood but also plays with your clit to actively give you orgasms to counter your cramps.

Gently rubs your lower stomach to further help with your cramps.

Or grazes it very lightly with his fingertips to give you goosebumps if he’s in a teasing mood.

Slows the pace after each orgasm as to not overstimulate you before picking it up again.

Overall treats you like a porcelain doll.

Would give you a break if you asked.

Even if you’re still bleeding

So long as you’re always close to him so he can keep you safe.

Soft gentle tugs to your clit force heavy breaths out through your nose, the occasional pinch making you clench around the soft pink tongue moving along your insides with your back tensing and arching off the futon briefly before a hand gently pushes down your stomach to press you back against the fabric beneath you in attempt to get you to relax, the tongue carefully moving back and forth as to not overwhelm your sensitive insides.

His eyes peek open when he feels your legs starting to tremble on either side of his face, the hand over your lower stomach carefully rubbing over the skin doing little to soothe you, his first pair of eyes looking at you due to your different than usual movements, unable to read any expression from your head being thrown back. “Are you alri-” He’s interrupted by your body falling limp against him and the unmistakable noise of you hitting your orgasm.

He’s quick to react and have his fingers gently rub at your clit, slowly licking over your leaking opening, his reasoning settling on your different reactions being from your current sensitive state. His eyes fall back shut again without his own hands failing to continue their ministrations, set on taking care of you and making sure you’re carefully brought back down from your own high as to not overstimulate you while you let him eat his fill.

Douma

Doesn’t even occur to him that you might be injured.

Knows that he would’ve been notified if you’d been injured.

Also takes full advantage of the situation.

Absolutely delighted to find out you’re a marechi.

He’s been surrounded by plenty women before and has eaten enough to know what a period is obviously.

As well as eaten marechi women before.

But has never stumbled upon a marechi woman on her period.

Is baffled that it never occurred to him to keep a marechi woman by his side for a monthly supply.

Immediately asks to feed off of you rather than asking to help with your cramps.

Used to have you on him 97% of times, now it’s 100%.

Eats you out wherever, whenever and however.

Very vocal about it.

Constant praises on your taste.

Gets actually hungry while tasting you.

But remembers that you’re a fragile human who he genuinely enjoys having around and therefore would rather not hurt you.

So he treats you as an appetizer instead.

And proceeds to eat one of the other women around after you’ve stopped bleeding.

Keeps you on him under every circumstance.

Even if Muzan calls him over.

Promises to do as Muzan says and be on his best behavior which he actually fulfills much to Muzan’s surprise.

If you were to actually be apart from him, he would ask in all seriousness for you to save your blood for him for later in a jar.

Another one who would forbid you from wearing anything under your kimono.

Probably forbids you from doing so even when you aren’t on your period.

Doesn’t even warn you when he smells you starting to bleed and immediately goes under your kimono.

If there’s anyone nearby when you start bleeding, immediately orders them to leave.

For your sake.

If it were up to him, he’d bury his face between your legs right then and there.

Messy eater.

Will definitely take you on his beanbag.

Will treat your period (as well as your fucking sessions) like some type of bingo or a list that needs to have locations where he’s taken you crossed off.

You feel yourself sink further into the large pillow beneath you with your legs kept hiked to your chest, loud continuous moans coming from the blonde between said legs, the incessant noises coming from him having won long ago against your own. A slight shift of your body moves your untied kimono further open with it finally slipping off your breasts and exposing your nipples to the cold air, the elegant fabric bunching around your torso between the folds of the pillow.

“Ohh, you taste just heavenly my darling.” Douma smiles after lifting his head from your bloodied messy folds, letting you take in the sight of his chin drenched in your blood, fluids starting to trickle down to his neck followed by his tongue swiping across it. “Now sit pretty for me and let me eat…” He coaxes in a low tone while slowly lowering himself, continuing to delve his tongue into your opening.

While a knot started to form in the pit of your stomach, the hollow filling in the pit of Douma’s own stomach started to grow, tempting him with having more than just a taste of your blood, but he couldn’t, he’d never forgive himself. He shuts down his thoughts and instead licks you with more vigor, his mind wandering to other women who he’d much rather eat before you, maybe the one who’d been just slightly less polite than usual when attending you, maybe she’d be able to satiate his hunger for a while.

Akaza

Is terrified when he smells your blood for the first time.

Especially when he notices what type of blood it is.

Immediately assumes the worst.

Thanks whatever higher power there is when he sees you’re fine.

Gets headaches from trying to keep himself in control.

And still refuses to leave you alone.

Absolutely would never under any circumstances let Douma get remotely near you regardless of whatever situation you’re in.

Would never suggest eating you out to relieve the pain because he doesn’t want you to think he’s using you for food

But wouldn’t blatantly tell you no if you asked.

Would need a lot of convincing to say yes.

Would be really worried because what if he accidentally hurts you.

Is also worried that what if he genuinely gets hungry while trying to make you feel better.

Would be very hesitant due to his rule against eating women.

But tries to convince himself it’s alright because he’s not actually eating you.

Because he secretly is very curious and tempted to try it out.

Finally says yes when your cramps get unbearable.

Absolutely loses it upon his first taste.

Would already eat you out regularly for his own pleasure.

But would do it with dignity composure.

Now gets overly pussy drunk.

Doesn’t stop even after you’re clean.

Just continues while waiting for the next wave of blood.

Eats you out like a starved animal when you’re on your period.

Another messy eater.

Doesn’t leave your side for your safety.

And your mutual pleasure.

Would enjoy you sitting on his face.

But fails to notice how he refuses to let you leave your seat once you’ve sat.

Despite eating you out mostly for his own pleasure, doesn’t forget yours and uses his fingers to give you as many orgasms as he can as a thanks for keeping him fed.

Has no shame in licking his fingers clean in front of you.

Makes sure to still give you plenty of head regularly after your period so you don’t feel like he just sees you as food.

Would wonder in the back of his head if your blood alone can make him strong enough to surpass the other upper ranks.

Would be damned if Douma found out what he’s doing.

“Are you su-” “Yes.” Akaza’s quick to respond, trying to hold himself back from yanking you down, instead, gently guiding you lower to take a seat on his face. It’d been a few cycles since he finally started eating you out during your period and in that time, he’d grown addicted, though that would be an understatement. And though he still much enjoyed spending his days face buried between your legs even outside your cycle, during was something far preferable.

In the last few times he’d helped you through your difficult time of the month, he started feeling as though it wasn’t enough, no, rather he wanted more, and so he suggested something new, something you’d never know if he’d thought about himself, seen somewhere or heard of. Once you feel your lower area come into contact with him a sigh escapes you with his tongue starting to move along you, pressing over your clit, licking between your folds, circling your opening and licking clean every crevice.

He continues to suffocate himself in the intoxicating smell of your blood and decides it still isn’t enough, not with you hovering. A yelp leaves your mouth at the sudden yank of your legs being pulled upward folded against each other by a pair of strong hands with you falling completely sat on Akaza’s face, a muffled moan heard from under you pulling your gaze toward him, taking in the expression of his eyes rolled to the back of his head while his tongue invaded your insides, refusing to stop tasting you.

Hi! If youre still doing requests, i have kind of an odd ask , but maybe some of the upper moons' reactions to meeting Muzan's wife (reader). I also really like whipped!Muzan so maybe the other demons' reactions to seeing the demon king doting on his wife. Thank you very much :)

Hi Anon! (^○^.) I actually love this request, so thank you for sliding it into my askbox ♥

Honestly I love a powerful man - especially a powerful villain - who's just absolutely in love with their wife (♥ω♥.) and would do anything for them, it just brings me joy.

Anyway! I'm rambling abit, but here is your request! I hope I've done it justice (^ω^.) Please enjoy!

Come again to request whenever you want cause I'm always open.

Muzan Kibutsuji being whipped for his wife + Upper Moons Reactions - Headcannons:

You know those types of men that are just unmovable pillars of stone - who look like they were carved from the finest marble by the hands of angels - who are always impeccably dressed with a voice of icy poison and just command your attention?

Who turn to the softest love-struck mush when with their wife

yeah, that's Muzan Kibutsuji with his wife (aka. you)

The finest meals, clothes and jewelry are yours with a click of his fingers - all done to make you happy, to see you smile

Anything that you mention briefly - doesn't matter if it''s a book or a holiday - its yours by the end of the day

Just one smile and a fluttering of your eyelashes has muzan on his knees - a singular pout of your lips has his mind running wild

You just have to breathe and Muzan's heart squeezes, breath stuttering in his chest as he looks at you in adoration

You could ask for the world and he'd give it too you on a platter

Muzan worships you

Each touch from you is a blessing to his skin

Each kiss sealed into him

Each word of love that falls from your lips make him drunk to hear, each sentence thick with a love that leaves hearts in his eyes and his heart thumping wildly

He wants to wear you like a brand - each mark you leave on him (bite marks and all) are worn with pride - and you (and only you) get to touch and mark his skin in such sensual ways

Under his wedding ring, his finger holds your bite mark, something that he begs you to do each day - with love-struck tears pricking his eyes - and it always makes him feel like he's properly yours

"My Love," He purrs with a voice a think velvet "My wonderful wife, my moon and stars, I love you for ever and always" and he kisses you so softly

Sometimes you have to stop this man from wearing matching clothes with you - "But Beloved,"he whimpers with a face liked a kicked puppy "I want us to match" - because he will absolutely wear a matching couples outfit

Other days he just likes sharing the same colour palette

When you worship him by placing soft kisses to his skin - his wrists, knuckles and faces - Muzan feels like he's on cloud nine

Upper Moons Reactions:

When the upper moons first met you, it was by accident - pure accident -they'd been summoned and it just so happened that it was when muzan was just in the midst of kissing you and bathing you with compliments

Kokushibou doesn't even blink and just stands in position like a trained guard, this sight has been something he's accidentally stumbled upon a couple of times before and honestly it makes him miss his wife

Because this isn't the first time he's met you but rather the fifth, the first actually time he met you, you were incredibly respectful of him and actually treat him nicely - you became tea drinking buddies - so he quickly came to like you

Douma/Doma genuinely shrieks - like an honest to god scream - before quickly going to make fun (not a good idea) about how loving Muzan is and, "Why don't you treat us this way Muzan-sama~ You're breaking my heart~"

Akaza looks away from such an intimate scene with respect since it felt wrong to look upon his lord loving his wife - although his heart does ache for some reason when looking at such a perfect loving scene

Hantengu starts sobbing while apologizing anxiously - actually very jealous at how loving the scene is, he wants a wife and to dote on someone

Gyokko simply proclaims it as artful and simply leaves it as such

Daki Blushes a deep crimson - it makes her want a husband to dote on her so much

While Gyutaro simply sighs before looking away - much like kokushibou and akaza in respect - with jealous crawling up his ribs at such love, he wants somebody to dote on and love him so romantically

The rain droplets over the roof. A storm was occurring; you sat beside Muzan in his sickly form. Dipping down a small towel in cold water and putting it on his forehead as you sat near him.

You were his fiancé to be soon married by him, but it couldn't be due to the state of his body. Your eyes couldn't help but produce tears from your eye, dripping down to your lap, as you stared at his miserable form. Feeling a cold hand brushing your cheek, "I hate it when you cry" Muzan muttered, you held his hand to your cheek as you tried to smile, but your lips faltered.

"I-i know," you whispered, looking at him, tears threatening to fall out, as you breathed in. "Just why do they have to be so cruel" your lips trembled, "Just why" you cried.

You took Muzan's hand off your cheek and gently placed it near the sides of his body. You looked at his him again, he was soon passed out, before you looked at the door opening up to one of the doctors assigned to Muzan.

"Good afternoon, Mrs. L/N," he said to you slightly bowing down to you, as you got up dusting off your kimono, you tilted your head at him and walked out of the room. Stepping down on the tatami floor, going outside, as the feeling of the cold dropping rain on your skin, staining your kimono, as you stepped backward underneath the roof.

Sitting down on the leveled floor, you back leaned on the pillar as you stared at the abyss of the sky. Your eyes soon closed as you slipped into slumber.

Before heard a loud thud on the ground, fully waking you as you ran almost tripping on the wet floor, as you quickly opened the door to Muzan's room, looking at him covered in blood standing for what you thought was the first time, his hand holding a butcher knife to the doctor head, that laid there collecting a pool of blood.

"M-muzan, what did you do" you whispered, covering your mouth in horror.

His mouth was still stained with a bright blue pigment on his lips, as he stood his ground without any help or distance at all. His pupil was formed like a cat and the color of crimson.

You stood there in silence before he dashed straight out you covering your mouth, as your eyes only stare at him with fear. You didn't know who he was anymore.

He looked at you straight through the eyes, your heavy breathing, making your heart pump faster. You looked at his nail that grew sharper than any sword you have seen before.

He soon took his hands off your mouth, cupping your cheeks, while tears threatened to slip out of your eyes, as you stared at him. Someone that once your lover, turns into a deranged animal right in front of you. You opened your mouth to say his name but were soon entrapped into a kiss with him.

Your pupils shake, from the sudden intimacy. Before closing your eyes leaning into the kiss.

Before he withdrew from our lips, staring into your own, as you looked at him bewildered by his appearance, "My precious, Y/N" He brushes your cheek, and his fingers brushed your lips.

"I'm no longer someone weak, not anymore" he whispered to you.

"M-muzan....you just murdered someone" You took his hand away from your face, as you backed away from his figure.

"Y/N, he was just a lowly doctor, who could do nothing but to bickered and give me nonsense creations of his medicine" he exclaimed, extending his hand to you.

You backed away more when he took a step away, your body melting with fear. "You're not someone who I used to love, your monster" you screamed out before dashing towards the door, before you could, muzan was right there.

His body leaning towards you, "Y/N, don't be like that" he spat, as he soon got annoyed by how you were acting.

"Get away from me" you lashed out.

You were too slow for a man not to catch up with you with his newfound abilities. He grabbed you, hid nails digging into you, as you winced in pain. "There is nothing to be afraid of," he said, trying to comfort you but you flinched away from his touch.

His eyebrows twitched, as he soon threw you down to the floor, and you yelped in pain.

You crawled away from him before getting pulled, his shadow creeping into yours. He kneels towards you. Before he looked at your figure on the ground as pieces of your kimono were off of your body, exposing your undergarments, "Muzan, please" you cried.

"Be gentle" you said.

His nails cut the thin pieces of fabric off your body, leaving your body bare. His eyes are hungrily staring at your naked body.

"Muzan, please promise me...if we do this, you'll stay with me " you begged, your lips trembling, you clasped his hand with your yours.

"From the beginning and end, my dear" he answered you with a kiss. He gently pried your legs open, his body between yours.

You closed your eyes, feeling his member sinking into your wall. As you registered the pain. You winced. His pace picked up, as he trusted you.

Every time he dragged himself out of you, plunging himself into you, you moaned in pain. Covering your hands to your eyes. His tempo frantic plunging into you, your body jolting from the tempo.

The pain simmering into pleasure, as he slides into you. As he held it down to your waist gripping it, his nail digging into drawing out blood.

"Shit" he groaned, as his animalistic thrust goes into you, pounding right into you. Your arms holding onto him, as he bit your collarbone, littering your body with love bites, the taste of blood going into his senses.

As his animalistic urges grew.

He dragged himself in and out of you repeatedly his pelvis brushed onto your own, and you moaned out. You felt a warm feeling growing in you, as you felt the core snap. A blow of heat washing through your body.

Your juices coating his dick, his thrust going in faster into you. Your breast jolts in the temp, bouncing with him.

The simple pleasure of making you hooked, feeling himself plunging himself into you. The room makes your body feel hot. You cocked your head away, releasing your arm from the grip.

His pace soon slowed down, and as his thrusts gets sloppier. His nail in denying further into your skin. Soon pouring himself into you, coating your walls white.

He groaned, his body leaning forward. Bruising your hip even more. You looked at his form through the tears on your thick lashes.

You're heavily breathing being heard, as you covered your sweating face.

Before he pulled out of your tired figure, you stare at him with sleepy eyes, "You did well, Y/N" he said, brushing the excess hair off of your forehead.
