18+, MDNI, Shinazugawa Sanemi is a filthy monster

Full of hot air. Annoying piece of shit, waste of time--

You and Sanemi approached the safehouse, scraped and bloody and pissed off. You felt every scrap of annoyance as an electric frisson over your skin, made irritatingly worse every time he brushed against you.

You stuck a palm out, trying to shove him further away from you, and only succeeded in shoving yourself further from him, so bizarrely immovable was he. His face, already stormy, snarled.

"What's your fucking problem?"

"Stay out of my space Shinazugawa--"

"--you're the one fucking staggering--"

"--yeah, well, it's hard carrying the whole team--"

Sanemi laughed, mirthless. Now bracketed by arching wisteria, in a tunnel to the door, he hammered his fist on dark wood, turning his back to you.

"Yeah, alright kid, the circus called--"

"What the fuck are you talking about, Shinazugawa--"

"--yeah, yeah, they want their clown back--"

The pair of you were too busy bickering, sniping and biting, to thank the elderly woman who let you in. She rubbed a single wizened hand down her face.

As you stormed away to the baths, the old woman caught Sanemi, saying something to him that made him spit feathers, apoplectic and vengeful. You didn't care to listen, and instead shut the sliding door, sunk yourself into the awaiting hot bath, and stuck your head briefly underwater to scream.

Somewhat calmed, but still brittle and fractious, you encased your body in a fine white robe, leaving your clothes aside to be de-bloodied by the house staff. Stepping out, you were greeted by the old woman who had welcomed you inside.

"Come along, dear. It's a good thing you two are married, I only had one room--"

You frowned, uncertain, and about to open your mouth to argue back before being unceremoniously shoved into a room, the woman a little too eager to escape from you before you could throw vitriol at her.

You turned on the spot, flustered, in a handsome traditional room. A large, squashy bedroll lay upon the floor...and Sanemi sat upon it, looking pugnacious and nonchalant.

"...get out of my fucking room, Shina--"

"Shut the fuck up. It's our room for the night."

You faltered, short-circuiting and drawing your robe closer to yourself, feeling so naked. Sanemi continued, stripping his uniform top off, throwing it aside. You felt yourself flush hot from head to toes, despite yourself, at his chest and back, all hewn stone and sculpture. He still didn't look at you as he continued.

"They only had one room. They were about to turn us away, so I convinced them we're married. You're welcome."

You fizzlecracked with rage, burning with mortification.

"You? Married to you?"

Sanemi bristled, offended. "What the fuck's that supposed to mean--"

"Oooo I'm your little wifey now am I? Lucky little Sanemi, so fortunate to have such a lovely wife protecting him in battle--"

"--you are such a pain in the ass--"

"--I'll be your dutiful wife, shall I? Here, let me take your clothes, dear one, I shall wash them--"

Sanemi stood slowly now, his shoulders hunched beneath something dark, approaching you like a tiger on the hunt. You continued your relentless mockery, furious at having to share a room with him, as if you could hide how badly you dreamed of him at night, when you weren't tearing each other to shreds--

"--cook meals for you, rub your shoulders and listen to all your woes. Such a perfect little wife--"

You felt yourself shoved back to the wall, squeaking as Sanemi's sweat and blood filled your nose. One strong hand clamped over your mouth, a forearm planted above your head. He panted, seething under your constant barrage of abuse.

His voice was so low, you could barely hear but for the tickle of his breath on your neck, and you shivered to feel him lock you in place, planting a knee between your legs.

"Yeah. That's it. You'll be my little wife. And I'll be your doting husband...if you don't want to sleep in the fucking forest for the night."

You trembled, raising your hands to press weakly at his chest, certain you couldn't hide it now, the longing behind the mockery--

Sanemi didn't move, a shudder running through him as your palms grazed against his nipples. His voice continued, gravelly under the strain of your plush body, caged against his.

"I'll listen to you tell me about your day...and I'll be interested, too. I'll actually listen."

You felt a blush smatter across your breasts, barely contained by your robe and not unnoticed by Sanemi as he continued.

"I'll tell you I missed you...and you'll take the piss out of me like always, but it's just because you missed me too and can't find the words to say it."

Your breaths came hot and fast, tear-filled eyes glimmering up at him as he deconstructed you, foreplay through playing house.

"And I'll pull you close...much closer than this...more like this--" Sanemi pressed his whole body flush to yours, and you groaned. Sanemi caught it in his palm, feeling his cock harden against his thigh at you, trapped like a little rabbit beneath him.

"And I'll kiss you...until you're squirming, and begging me for more. And I'm a devoted husband, so I'll undo your robe...and slip my hands inside to squeeze you so hard, you bruise, until you're all wet and peachy for me..."

Your head swam, feeling yourself wetten as if by some Pavlovian magic. You clamped your thighs around Sanemi's knee, his eyes dark to feel the heat of your empty core against him.

"...and I'll get you ready with my fingers...'cos I'm big, y'know? And you're great at taking me...but I like to feel your cunt shaking around my hand, while I fuck you with it."

Your fingernails pressed crescents into his pecs, now, supple and pliable against the wall as he fucked the fight out of you with his words, all this time just tearing each other to shreds just to avoid telling him and now what for if it never worked all along were you always so fucking obvious--

"And then...I'll use some of that soaking little pussy cream to cover my cock, jack it off it a few times to get it ready for you, but I'll lick the rest off 'cos I know you like that--"

You moaned into Sanemi's palm, squirming hard enough to free one breast, and Sanemi cursed under his breath, his voice rough and wavering as he drank down your trembling curves.

"...and 'cos I'm your husband...I'll fuck into you all at once. And I'll fuck you, and fuck you, until you're yelling out my name, but it won't be Shinazugawa anymore 'cos that's your name, too, wife, it'll be Sanemi instead...or something like that, anyway, 'cos I'll be honest, you'll be too fucked out to talk properly when my cock's splitting you in half. Finally. A way to shut that fucking potty mouth of yours."

Your hands trailed up his chest, beginning to wrap around his neck, involuntarily rubbing your clit over his knee with a shaking moan, throbbing with the promise--

Sanemi released you, stepping away abruptly, leaving you cold and gasping and wet against the wall.

"As your husband, anyway. Not that I am. So shut the fuck up...and go to bed."

You sunk to the floor, stunned and speechless, unable to form a single comeback. You gasped up at Sanemi, his back to you as he undid his hakama. His head, all ruffled white spikes, came up once more with an ah! of realisation, and he shot his final, critical hit.

"...and I'd cum inside you. Obviously. Doting husbands like you all round and pretty and full of their seed, right?"

Saving Genya from his big brother only to make out with Sanemi

Pairing: Sanemi x fem!reader

Word Count: 2,9k

Synopsis: It was never an easy job, being the only one who's able to calm the wind hashira down. There was never more than respect and understanding between both of you. Until you bodly decided to stand up for Genya, until Sanemi finally reveals his true feelings...

Warnings: We're talking about Sanemi so language at violence lol, aggressive making out

I love love love Sanemi and I desperately hope you do as well hehe, enjoy and leave a comment/like/reblog <3

There he stands with his hot temper filling the air and his ruthless beatings torturing the poor souls in front of you. Hashira training never sounded like fun to you, especially when you consider who you’d have to deal with.

Sanemi Shinazugawa, especially.

“Get back up, brat. We’re not finished yet.”

You watch from afar as he hits the poor red-haired poor over and over again. Without any mercy, without the slightest hint of regret. And still, you can’t help but ponder about the way his arms flex and show every vein that decorates his skin. How he moves so effortlessly that your eyes are almost unable to follow. No, it’s not a secret that apart from being a madman, Sanemi Shinazugawa is hot as hell.

And your crush since you joined the demon slayer corps.

“Don’t you think that’s enough for today? The poor boy isn’t even able to stand up straight anymore”, you interfere when he’s about to hit him once again.

"Oh, I'm sorry, I didn't realize you were the expert on disciplining. How about me fetching you a chair so you can supervise more comfortably?”

All pairs of eyes are set on you while you step towards the scene in death silence. Apart from everyone else, you aren’t here to train under Sanemi. No, you are a very capable demon slayer yourself, so good that you even managed to beat Mitsuri from time to time. You definetely don’t need Sanemi to train.

In fact, you are here because you’re the only one who is able to tame him apart from Kagaya-sama himself.

"Well, if you ask me so nicely, a chair actually doesn’t sound bad for the next time. Meanwhile, how about we wrap this up? Enough's enough."

Sanemi’s venomous eyes meet yours, tempting you to lose your cool. Within the past few months, you’ve learned how to act around him and that his actions don’t reflect his true feelings at all. Deep within, he is the most caring and compassionate person you’ve ever met, so tender that you’d simply melt away in his touch. He never failed to protect you even if not needed, always made sure you are save before looking out for himself. Damn, he even left his desert for you to eat.

But on the other hand, he’s very good at hiding that side of him.

“Fine. Call it quits for today then. But we two will have a talk later”, he finally mutters before turning around and disappearing without any trace.

Your heart skips a few beats before you’re able to think straight again. Oh, how much you adore him. Just the sheer thought of meeting him alone sends shivers down your spine even though nothing ever happened between you two. After all, you’re only here to look out for him, right?

“Thank you for standing up for me. Now you’ll get in trouble for helping me out”, the red-haired boy lying in front of your feet speaks out while dragging himself up.

“Oh, don’t worry about me, I can handle him. Are you alright?”

In the matter of seconds, your eyes scan his body for serious injuries. Nothing, as you expected. Even though his training methods seem rough, he’d never allow himself to truly lay hands on another corps member. Not even him, Kamado Tanjiro. The boy who has what Sanemi always dreamed of.

“Yes, thanks to you. We really need a break after training day and night. Sorry, may I ask you for your name?

“My name is (y/n). Nice to finally meet you in person, Kamado Tanjiro.”

His eyes widen in an instant when you tell him your name. Even though you’re not a hashira, it seems like a lot of corps member know you. A decently skilled swordswoman, a trained doctor who made sure that no one ever died as long as you were around.

“The angel”, he breathes out.

“What an honor to meet you in person!”

In an instant, he gets on his knees and places his head on his flat palms. A pose of deep respect, so intimate that your cheeks heat up in an instant.

“Please, lift yourself off the ground. I don’t deserve your praise-“

“You deserve so much more than that!”, Tanjiro interrupts in an instant.

“Leave her alone. Can’t you see that you’re making her uncomfortable?”, another voice mutters from behind.

A very familiar voice you haven’t heard in quite some time, that makes your heart jump up and down in joy.

“Genya!”, you cry out.

You waste no time. In an instant, you lunge yourself at the now much taller boy and wrap your arms around him so tightly that he cannot escape. Oh, you really missed him. Even though Sanemi states over and over how much he hates his little brother, you always had a weak spot for him. Maybe because you’re able to see his soft side as well or because of the cute way he blushes when you look at him.

“Genya, are you alright? Your face is so red-“

“SHUT UP”, he barks at Tanjiro while you giggle to yourself.

“Why didn’t you send me a crow like I told you to? I was beyond worried about you. But oh I’m so proud. Did you really help to kill an upper moon demon and supported your friends?”

“Well I-“

“Yes he did! He was a big help for all of us!”, Tanjuro interferes immediately.

“(y/n), didn’t I tell you we need to talk?”, someone suddenly barks from the inside.

All color drains from Genya’s face immediately as he turns around with you.

There he stands with his arms crossed in front of his muscular chest, eyes almost piercing through you while the vein on his forehead threatens to pop any minute.

Your heart sinks in an instant. No, don’t let him control you like that, not when you know that he’s just…jealous?

“I needed to talk to Genya first”, you clarify.

“(y/n), please don’t-“

“Oh, is that so? Why would you even look at that trash?”

Thick anger rushes through your veins like the flood. If there’s one thing you hate about Sanemi’s attitude, it’s the way he talks about his little brother.

“I’m looking at you as well, don’t I?”

He flinches ever so slightly, his furrowed eyes now piercing through you like a thousand knives.

“Get inside. Right now.”

“Get some rest you two”, you quickly shout over your shoulder before you disappear into the house with a furious Sanemi by your side.

He slams the door shut behind you so rapidly that it rains plaster.

“What was that, huh?”, he speaks out with threatening low voice.

“I asked your little brother about his mission.”

He cages you between the wall with no way to escape, dangerous eyes locked with yours.

“I told you to stay away from him.”

“And I told you that I don’t care.”

“Why don’t you leave, then?”

“Because I’m the only one who’s able to tame you down”, you bite back.

He huffs in sheer annoyance while pushing himself off the wall. Why does he have to look so vulnerable and strong at the same time, so scary but also mesmerizing?

“You won’t force me to talk to him”, he finally speaks out.

“I want him to leave the corps and get as far away from me as possible.”

“Away from you or away from the danger?”

“I don’t care about him.”

“So you don’t care about me as well?”

Thick silence hangs between both of you while you stare at each other. To this day he never revealed how he truly feels about you. Does he hate you, respect you, love you? You might never know. But your influence on him speaks for itself.

“Go to sleep. We’ll get up early tomorrow.”

Without another word, he leaves you standing in a new wave of ponderings and emotions.

-a few hours later-

Your eyes dart open for no reason. Aimlessly, your orbs roam around the dark room, ears searching for a single sound.

Voices. Shouting. Blows.

Blows?

“Big brother?”

Your heart drops to the floor. That’s Genya. Why does the floor start to vibrate now?

Out of instinct, you yank out of your room, follow a wave of destruction until you finally get what’s going on.

There they stand. Genya with fright written all over his face and Sanemi with orbs so empty you’re almost able to see through them.

Your guts turn uncomfortably as he speeds forward so fast that your eyes are almost unable to follow. Fuck, is he about to pierce through Genya’s eyes?

You waste no time. In the matter of milliseconds, you drag Genya to the ground and therefore safe him from Sanemi’s merciless attack.

“Sanemi.”

You breathe out his name like a prayer.

“Get out of line, (y/n).”

“I can’t allow you to hurt him!”, you cry out, hands still holding onto Genya’s trembling body for dear life.

“You leave me no choice, then.”

It happens faster than you’re able to think. He dashes forward while grabbing the handle of his sword tightly, his eyes and blade darted towards you.

But you don’t even think about leaving Genya. No, you stand your ground in front of him, glossy orbs watching as his blade crashes down straight towards your face.

Until it stops.

“I said move”, he hisses through gritted teeth.

“And I said I won’t. Leave Genya alone.”

“Are you really putting up a fight with me, (y/n)? Here, right in front of everyone else?”

You couldn’t care less about the stinging fact that the others are watching you drowned in fear. This goes too far without any doubt.

“You don’t have to do this, Sanemi. Not when we both know you love your little brother dearly”, you breathe out.

“Come on Genya, let’s leave”, Tanjiro’s voice mutters behind you, causing a wave of relief to wash over you.

“I don’t love anyone. Not him, not you, I don’t give a shit about anyone around here”, Sanemi barks back at you with nothing but hatred spilling from his mouth.

Genya doesn’t deserve those words reaching his ear. But apart from that, you can’t escape the sting that fills your heart with agony.

Him, not loving anyone? Of course you never really expected the wind hashira to actually like you back. Of course even him respecting you is more than you could have ever asked for. But somehow you still hoped. Each and every night, you imagined what if would feel like to lay in his arms while listening to his steady heartbeat. Every free second, you pondered about how his lips must feel pressed against yours, how it feels to fall asleep and wake up next to him.

And now he tells you that you mean nothing to him.

You swallow hard, desperately trying to avoid his gaze at any cause. No, you can’t afford to lose yourself right here when everyone is watching.

Out of instinct, you straighten your shoulders and cross your arms in front of your chest.

“If that’s the case, I’m leaving. Good night, wind hashira.”

You don’t care about waiting for an answer. All you want to do right now is going back into your room, going back into safety where he’s not around. How stupid to even consider that Sanemi Shinazugawa could feel anything apart from a little respect for you. You, nothing but an ordinary slayer, still too weak to be called a real hashira. You, apparently nothing but a fool.

Hot tears start to swell up your eyes and cause your vision to get foggy. You never allowed yourself to cry over something so minor. What did you expect, a gut-wrenching love story? With the wind hashira?

“Why did you turn your back on me?”

You flinch so hard that you almost trip over your futon.

“What are you doing here?”, you cry out.

Fuck, this is him, without any doubt. What on earth is Sanemi doing in your room? Just now, when you’re looking like a mess.

“Are you crying?”

“Even if I do, why would you care?”

When your gaze drifts towards his, you feel like drowning and taking your first breath at the same time. He looks so distressed that your heart wrenches all over again. Like a lost puppy, he draws closer until he cages you against the wall. His eyes seem to stare right through your soul, make it hard to produce a single logical thought.

“Why would you even think that, idiot?”

His hand yanks your chin up, forces you to stare at him even more intensely.

“Because you said so yourself”, you bite back.

“You shouldn’t have interrupted me in the middle of teaching Genya a lesson.”

“Teaching him a lesson? You’re breaking that poor boy’s heart-“

“Breaking him? I’m saving him, goddamn!”, he blurts out so suddenly that you shake.

“Saving him? What are you t-“

“Poking his eyes out isn’t that big of a deal, he’d definitely survive. But his career at the demon slayer corps would have been over and out, he would have been saved”, he mumbles frantically.

“That would have meant he’s save, that would have meant he doesn’t die in this shit-“

“Sanemi”, your hands grab his face gently, try to get him out of his constant mumbling.

“He’ll die just like our mother did.”

“Sanemi.”

“I can’t fucking protect you all. Not when you’re around as well, not when you’re not listening just like he does-“

“Sanemi.”

When your eyes meet his, he looks like a troubled child scared of thunder. His glossy orbs stare at you desperately, make your heart ache all over again. All that rambling, giving Genya his coldest shoulder…to protect him?

“You’re just as reckless as him. Not looking out for yourself. What am I supposed to do without both of you around? What if I lose you two as well?”

“You won’t lose anyone, I’m good enough to-“

“How can you know?”, he screams into your face, his voice vibrating through every cell of your body like thunder.

“How can you promise you won’t die? One wrong move and you’re gonna bite the dust. Or you’re at the wrong place at the wrong time like Rengoku-“

It might be the stupidest thing you’ve ever done in your entire life, so reckless that you’ll lose Sanemi completely.

But you don’t care.

Before he’s able to talk about the grief within the past any further, you crash your lips against his while holding onto his face for dear life.

Over and over, again and again until your mind finally shuts up, until it’s only you and Sanemi and his puffy lips against yours.

He wraps his arms around you so tightly that you allow your knees to give in, bodies resting against each other so desperately that you feel like dreaming. Countless nights you pondered about the way his frame feels pressed against yours, what the wind hashira might taste like.

Oh, the reality is so much better, so good that you have to convince yourself you’re not dreaming.

“You’re driving me insane. Since the first time I saw you training with Obanai, since you beamed at me with that sickening gorgeous smile. I can’t escape you. I can’t fucking lose you”, he hisses against your mouth before entangling his tongue with yours all over again.

Sparks fly, stars take up your sight completely as you threaten to choke on all the affection and love that hits you with full force.

“Why didn’t you tell me?”, you breathe out.

“And risking you’ll never talk to me again? You have to be out of your mind.”

“I’m out of my mind because of you. Because you make me feel all those strange things”, you puff out.

Faster than you’re able to react, he pulls his face away from yours enough to almost drown inside your glossy orbs. For a moment, all the does is staring at you as you desperately gasp for air with your chest rising and falling rapidly. This really happened. Did you really make out with the wind hashira after he tried to murder his little brother, after all the fighting and rambling of today?

“You’re my weakness, (y/n)”, he finally blurts out.

“And I hate that power you have over me. Especially that everyone else knows it.”

You tilt your head to the side. Oh, that’s so true. After all, this is the reason why you were sent here. You are here to make sure he doesn’t go too rough on his students, that his hot temper is kept at least a little cool.

Well, given the heat that radiates from him at this very moment, the last part definitely didn’t go as planned.

“They know about my feeling for you as well.”

His eyes widen while he stares you up and down in sheer disbelief.

“Stop fucking with me”, he grumbles.

“You were too blind to realize that I loved you for so long while I didn’t even think about the opportunity that you might like me back”, you admit with your cheeks turning as hot as the sun.

“You fool.”

He yanks your chin towards his face, a small smile decorating his usual so irritated face.

“I’ll definitely never let you go again now.”

His lips crash into yours and leave your mind blank all over again.

“But I’ll still kick your ass for talking to me so disrespectfully and interfering with Genya.”
