don't ask-

I'm a little nervous about posting my work here for the first time, but I hope you enjoy it! This is a short essay about my character and my friend's character in the Demon Slayer setting, so don't be surprised by the weird names. Both are adults! Enjoy reading~

Warnings: nsfw, modified clitoris, some roughness, girl dominance, anal sex, mention of oral sex. Minors do not read further! Miyamoto feels like he's just suffocating from the frantic pace, like his thighs or head are about to give out on him, while his groin is so wet from the huge amount of lube dripping down it, making the futon underneath them wet.

Under him… And her. *****

"Vales-chan, are you okay?" the Gyomei student asks with slight concern, visiting his friend in the room reserved for her at the Corps headquarters, where the half-demon was currently resting, but did not come out to train.

But Giyu-san wanted to practice the technique with her again…

"I'm okay…" the girl quietly responds, shaking her head while scratching her pointed ears with her claws, like an animal, not wanting to leave the blanket.

Miyamoto frowns sadly, worried by such an answer and behavior.

Have demonic fits in her behavior overtaken her now? "I can help if you tell me what's bothering you, - he assures with a soft smile, to which she turns her "flattened" pupils to his figure."

"…" *****

Vales growls and chokes on saliva, mercilessly moving on the flesh of the former nichirin bladesmith, drool dripping from her bared fangs and flowing from her lips, while she again and again rises and falls on Miya's hot cock, pressing the man's hips into her poor futon, holding him under her without effort.

His eyelashes flutter, his mouth and lips are wet with her juices, because she literally fucked his lips and tongue with her hips, not letting him breathe until he thoroughly licks her pussy, making her see stars.

Miyamoto is lost in how many orgasms they both experienced, he lost count.

He simply prayed to all the gods and training from Lord Gyomei and Rengoku, still breathing under the onslaught of the half-demon.

He doesn't even know if she's so hungry herself or if it's her nature from her father… ***** "Miyamoto-kun, I have a problem…"

She doesn't hold back her animalistic, wild moans and growls of delight and pleasure, her long tongue sticks out of her mouth, also opening a small fanged mouth at the end, testifying to her pleasure.

Her demonic essence is now expressed especially brightly, reflecting on her body, her hips are completely blue and have changed into her beautiful paws, behind such a juicy ass, not hidden now by the pants of her fighter uniform, her tail with a membrane is visible, with which she hits his legs, while she tortures his hips and penis with her pace, while her pussy seems to be trying to devour the poor blacksmith, milking him dry.

Without feeling the power of authority that a Hashira or a male demon would have, she takes full control, fucking Miyamoto until he loses his pulse, leaving bites and scratches on his body, growling and snarling, a real fiend of the night. ***** "What can I do for you, Vales-Chan?" *****

The growl in her throat grows even after the orgasm that they both just experienced again, her modified clitoris, now large and similar to some kind of sea creature, still leaking and pulsating, until she does not take her eyes off Miya. "On your knees." *****

The poor man just cries and whines, feeling the demoness holding his hair, leaning on top of him, pulling his poor disheveled tail, growling and literally screaming with pleasure, while her hips are madly pounding into him, while she is ripping him from behind with her… Cock.

Gods, she can use it as a cock, and she does not spare it, taking everything she can.

His ass is red from the slaps of her hips, the stripes of her claws on his skin are stinging, making him whine, he does not know how much more he can take.

It seems like she's going to fuck him to death- *****

"You're so sweet, Miyamoto, I could eat you whole~ You helped me so much, I'll have enough for the morning~" a hoarse but gentle voice coos in his ear as he lies on the futon torn by claws, feeling himself leaking after her, while Urokodaki's student licks her lips, then gently kisses his temple, making him sigh in embarrassment."

"Good boy~"

Dealing With A Marechi S/O On Her Period.

Main Masterlist

KNY Masterlist

Muzan Kibutsuji, Kokushibo, Douma, Akaza x Fem! Reader.

Warnings: Blood, smut, sexual themes, oral sex; female receiving, oral sex during period, face sitting, mentions about fingering, drinking blood, eating human flesh.

Summary: Headcanons on the upper three and Muzan helping a marechi s/o through her period while keeping their stomachs full.

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.
