hey, i'm Kai! i enjoy writing about Hakuji/Akaza x Koyuki, which is mostly nsfw content of them.
WARNING
in broader terms, there will be cannibalism (as some of my fics are set in the world of demon slayer), gore, sexual violence, and psychological effects/damage. check my rules for a more detailed list of what I will and will not write.
I dont usually like venting on my accounts. it seems unnecessary and I feel like im doing it for attention unlike others who are doing it to genuinely say how they feel.
however, today has been outright awful. I woke up to my mother screaming throughout the house. this kicked some sort of panic mode within me and I'm not necessarily great under pressure. I fumbled and my mistakes caused my mother to scream at me even more so. I wont go into great detail of what she was screaming about, but it was concerning my little brother—who is disabled and in need of our help.
after she stopped screaming, she continued to go on this tangent of how "back in her day" she would get punched for being so slow. she says I practically have no brain cells, that I have no critical thinking skills, and I'm, essentially in one word, retarded.
I usually try to keep a cool face with my mom because I know how she gets when she's angry. my older brother and I both know so we both just do what she says and try to get everything out of the way to avoid talking to her faster. that's just how it's always been for as long as i can remember.
yet, today I've cried about 3 times and my thoughts have been nothing but about this morning. I've already asked my older brother if I can go sleep at his gf's apartment this weekend because I just can't stand being around her. everytime I try to build any self-worth, she manages to tear me down within a few words under 5 mins, destroying any remains of my self-esteem. I love my mom for what she's done, but I do not like her as a person.
it's naive but I want my four years of college to go by quickly and im successful, and I get to leave my home to build a new one with my boyfriend.
Involves: Cunnilingus, Non-con, Minimal bondage, face-fucking, overstimulation, Twins AU(no incest), Mentions of size kink, Mentions of praise kink, Obsessed Hakuji, and poor Koyuki

Koyuki forgot how they began and how she ended up in this position.
To be fair, it was hard to remember anything when her clit was swollen and red, her skin flushed, and Hakuji's head between her legs.
She tugs on Hakuji's hair with her rope-bounded hands, "Haku... please..ahh.. that's enou-enough."
At the end of the bed was Hakuji, and his only response was a shake of his head as his tongue continued to flick her clit, causing her to jerk and her legs to shake. He was in complete bliss just like this: his tongue ravishing her pussy as he stuffs his nose into her nub with his eyes closed. The sounds of him slurping the juice out of her every chance he got mortified her very being.
She hoped in that attempting to bury her tear-stained face into their sheets, they would eventually stop their torment and give her body the respite it needs.
Usually, Hakuji was so gentle with his touches; he treated her like she was crafted out of glass. A pretty thing that would fall into pieces the moment it was even grazed. With this kind of thinking came his praises of how good she was taking his fat cock, of how he would massage her tits to comfort her whenever he stretched her out, and how he would ensure she never went past her limit. Now, his large, calloused hands that engulfed her own are bruising her thighs as he holds her apart. His unrelenting tongue against her pussy had created cracks in her glass skin, close to shattering her mind. She wasn't escaping him, and it wasn't like she could either way with the ropes around her wrists.
The ropes were Akaza's idea. Tonight, he seems sweeter with her than usual as he would always fuck her until she couldn't breathe. His brute nature—starving to fight any other man that could challenge him—naturally carried into their bed too as he would dig his incisors into Koyuki's flesh each time he decided to cum inside her. Not only that, he was infuriatingly indecisive when it came to her; Akaza could never choose whether he wanted to edge her until the sun rises or he would force her to cum until the sun sets. In the end, she would cry for Hakuji's hand to help Koyuki escape from his own twin's needy clutches. He watched his lover become undone from his own blood, and her body would tremor in her puddle of humiliation.
Speaking of the devil, Akaza at the right side of their shared bed, grasps her cheeks with his thick fingers and turns her teary eyes towards him. He wipes her tears with his thumb as he gives a roguish smile, "What's wrong?"
With sniffles and an abundant amount of tears, Koyuki begs, "Make...Uugh..make him stop, 'kaza! I..can't. I can't do it.."
For a moment, Akaza brushes her soft bangs—sticking to her forehead from sweat—to the side as Koyuki pleads for his mercy. He then snatches her chin to make her eyes face Hakuji's blues, "Princess, I don’t think I could even if I wanted to. Look at him."
Hakuji, obsessed with milking everything he could out of her. His eyes half-lidded as he stared her down, pinning Koyuki further into the bed with fear, he wasn't going to stop. He wanted to see every expression he could coerce out of her as he circled her clit with his tongue, as he grazed her most sensitive spot with his teeth, as his mouth engulfed her pussy, and dipped his tongue as far as he could, collecting every drop. All she could do was let him as frail frame, instinctively, writhed and shriveled underneath them.
Akaza mindlessly pinched at Koyuki's nipples as he began to unzip and remove his pants. His girthy cock, veins and all, and the red tip already leaking precum, sprung out. He sits himself to the right of Koyuki's head, where her face would be level with his hard cock. He rubs the tip of it against her plush lips, smearing the precum against her mouth. Koyuki could only beg again to wait and attempt to tug Hakuji off with her bound hands
He only pats her head and smiles, "Koyuki, don't be selfish. It would be rude if you didn’t let Hakuji have his fun, and it would be even ruder if you tried to refuse me too."
Tears began to pour out of her soft pink irises, the snowflakes in her eyes only tempting Akaza to tease her more, but he was too impatient for any of it.
"Now," he presses her cheeks to pucker her lips, snickering at how her face resembled a cute chickling as a result, "open up, please."
The tip of Akaza's cock breaches past her cum covered lips, it's heaviness weighing against her tongue. As he pushes himself deeper into the warmth of her mouth, she gags when the tip of him presses against the back of her throat, kissing her uvula.
"Take it easy. I know how much you struggle taking me."
Soon enough, his cock glides down the end of her throat to where her nose presses against his black pubes (Akaza dyes his hair pink). Koyuki shuts her eyes as tears continue spilling out of them, only feeling soft pats from Akaza's calloused hands on her head, with her rigid body slowly relaxing from the contact as her lips adjusted to being stretched taut.
Breathing properly was a struggle already with Hakuji using his mouth and tongue as a human vacuum. Now, Koyuki can only concentrate on breathing through her nostrils without gagging. The pace of Akaza's thrusts against her face quickened with time; meanwhile, Hakuji continued to bury the lower half of his face with a few "breaks". The breaks lasted for less than a minute and the minimal distance from his starved tongue to her glistening cunt was an inch. As he took breathers, she could sense his hot breath blow into her clit, sending goosebumps under her skin and up her body. His time training at her father's dojo gave him an immense amount of stamina, earning him the ability to go for so long without air.
Her brain dissolved into a fuzzy mess as her pussy continues being tortured from Hakuji's pink muscle. Each time Hakuji let go of her clit for a second, her pussy would tingle as it felt the mix of cold air and his breath. And each time her walls squeezed around his lingua, it pushes him to devour more of what she can't contain. Whatever she couldn't hold back anymore, he'll take all of it and ingest what he could. He would do it until his skin became pruney from drinking her essence; until his teeth rotted from Koyuki's sweetness; until his brain reformed itself to only remember her taste.
Slurping, gagging, groaning and the wet sounds of sex filled the room. Akaza's hips were controlled as he was careful enough to not smash his pubes against Koyuki's face, but still reckless enough to have her gag with each push down her gullet. Overwhelmed couldn't describe how she felt. It couldn't describe the ecstasy of Hakuji's tongue against her sensitive bud as he finger fucked her to completion again. It couldn't describe the pain of having her hair being pulled towards Akaza's cock by his own hand. Every touch, sound, and sensation set her skin on fire and her nerves frayed.
Eventually, she felt herself melting into their damp bedsheets they all shared. Her senses blur together as each brother takes their time with drawing out every last moan, jerk, and the roll of her eyes from Koyuki.
At last, she felt Hakuji finally pull away and she couldn't feel more relieved, yet her eyes still tears up at Akaza's cock stuffing itself down past her uvula.
Akaza, sweaty and pissed, his cock leaving the blanket of warmth that was Koyuki's mouth with a loud pop, "O-ohh..so you're..fuck.. finally done? Is it my goddamn turn now?"
A tiny smile shimmering with relief climbed up her face. Koyuki heard her own heaves of her chest as her agape mouth collected what oxygen it can. Shivering from the cold air completing hitting her pussy this time without Hakuji's head shielding it. Her shoulders loosen in tensity; her brows stops furrowing; her body on fire as she pants from fatigue plaguing her; and her hair stuck to her skin from the layer of sweat.
Koyuki rests her eyes with a growing smile, allowing her body the rest it craves, ‘Sleep..I need to sleep-’
CLINK.
Her head snaps to the sound of metal. Disoriented from the number of orgasms ripped from her body, time had went by slow. As she processed the man before her, to Koyuki's horror, Hakuji was taking off his belt and pants.
In a panic, she began to thrash and push her feet lightly against Hakuji's abdomen as an attempt to push him back. The bottom half of his face was drenched and shined from just her cum and his spit. His eyes possessed and entranced on her sopping cunt. He looked like debauchery. Looking at him made Koyuki's stomach churn and her mortification and shame rose tenfold to where her cheeks burned greater.
His voice was ragged and his pale blues were bewitched, Hakuji grunted, "Not yet."
Swiftly, Hakuji seized each of Koyuki's ankles with one hand and split her apart once more. Terrified, Koyuki began to wail and squirm as she was held open for Hakuji's fat cock, the spit and cum made it easier for him to slide in, but the burn of just his tip still has her choking on her own sobs. Her fleshy walls that were overprepped adapted to his girth and began tugging Hakuji closer, displaying the completely opposite of what it's owner truly desired. Her delicate wrists burned against the ropes as she dug her nails into her palms.
Koyuki who is panting, sweaty, and in a frenzy, she pleads but it falls on deaf's ears, "Please! Haku! Ha-Haku..Haah! Stop it!"
She twisted her dizzy eyes toward Akaza's yellows, full of lust and delight at seeing her desparate for his assistance—knowing full well he'll do nothing but watch, taking on Hakuji's usual role in the bedroom—, "'kaza, make him stop! I don't want to do this...I don't!"
Koyuki, lightheaded, felt how he filled her in as Hakuji bottoms out inside her. His tip never failing to kiss her cervix. The spot that always made her eyes roll back, that caused her vision to become white, and had her drooling. Koyuki's cunt pulses around him as she cums just from Hakuji burying himself in her. His groans and sighs of relief were audible as he tilted his head back from the pleasure of having her tight pussy clench around him. Her cervix suckling his very tip, seducing him to go any deeper if possible. His hands, the same ones that would caress her every night, digs into her hips—his grip will leave bruises for days—to keep her trapped as he slowly thrusts himself. Watching with such intensity of how his cock disappears into her pussy then come out covered in her juices. The slosh of Hakuji's spit, her cum, and his precum seeps onto the bed and echoes throughout the bedroom when his hips slap against her bottom.
She heard Akaza beside her click his tongue before grasping her nape to push her closer to his cock, "Didn't we agree that it'd be rude to stop Hakuji? Now, Princess, open your pretty mouth for me. I didn't get to cum yet.”
I would like to ask a question, Im not sure if you would reply. But isnt Koyuki a minor for suggestive content? Or maybe shes aged up?
hello!
koyuki, in the original works, was 16 years of age when she married hakuji, an 18 year old boy. when I write with fics in the KNY setting, I'm assuming that they will have to consummate the marriage through the act of sexual intercourse. of course, it's normal to not have sex after marriage in the modern age, but I believe this was normalized for their time period.
for the modern AUs, most of the time I imagine Koyuki aged up but I don't explicitly say it, which is my fault there. however, I'd also like to clarify that this is a NSFW account written for dark content. there are going to be topics that are taboo or not suitable for young audiences or people uncomfortable with this. when it comes to age, I'm comfortable with writing about age gaps of Koyuki being at most mid 20s with Hakuji/Akaza being 30s or early 40s. I will not write about Koyuki, 18 or younger, with a man who is 20s, 30s, and older.
the only time I've written about underage content was my AkaKoyu smut fic, "Say It". in that setting they are both highschoolers. I don't believe the exact age was mentioned in there, but I grew up with the idea that it's normal for teenagers to have sex as long as you are performing it safely with consent. not to mention, I just transitioned out of highschool myself and into college, so in my eyes—during the time of writing that fic—i didn't think there was any problem.
another thing I would like to clarify is that along with a dark content account, I believe in the fact that you can write fictional characters however you want them written as they don’t exist. they don't have feelings, emotions, or rights as we do. although, that doesn't mean I'm going to write about necrophilia or pedophilia as that goes way past my boundaries, but in real life, these acts should be condemned for as that harms real people.
if you don’t like what i've written in this answer, disagree with my perspective, or dislike this blog, please feel free to block or mute me and to move on.
it's really cute to see Koyuki almost on the verge of tears. you shouldn't see a cute girl like her cry, but it's too endearing and almost gets you turned on
It would be soo cool to read an demon koyuki x slayer hakuji fic... psssst... pssst...🤔 PSSST.. the angst potential here is crazy.. do..you...see...the...vision...??...?
YES YES! I definitely see the vision anon!
the backstory could definitely be how the day hakuji went to visit his father's grave, he comes back to find the dojo splattered in blood. dead corpses and hollow husks of bodies of students across the floors. his master's body being consumed as he finds his wife munching on her own father's body.
now, Koyuki could either attack him (which is most likely) or could attempt to run away as the sun is almost below the horizon. if Koyuki attacks Hakuji, it could be like a tanjirou and nezuko situation, where he attempts to hold her back from eating him before being saved by another slayer coming to the scene. Or she tries to run away from him and Hakuji tries to pin her down from doing so.
we could also take this in a different direction where Hakuji comes back later than expected, and all he finds is a bloody dojo with corpses that have missing limbs. his master dead and his wife disappeared without a trace.
going with this route, the angst would be intensified if he becomes a demon slayer for one selfish reason: to find his wife. Would he care about protecting the weak? I think he would to a certain extent as he definitely wouldn't let someone die, but his wife—Koyuki, the one he promised to protect—is his utmost priority (if she’s even still alive).
the only signs that Hakuji has that Koyuki still walks upon the world are rumors of seeing a petite woman in a pink and white spotted kimono, and a strange snowflake hairclip who looks incredibly weak, so she would have, preferably, a man to be last seen helping her before they abruptly disappear into the night. this is the only thing that Hakuji latches on to because if he didn't have anything then what would be the point of living a life without Koyuki?
now, when they finally meet a last, imagine Hakuji's pain of seeing his wife, the one he's absolutely supposed to protect the most in this world, and now he has to protect others from her. there would definitely be a huge sense of failure coming from him as he felt he could have somehow prevented this.
i believe he said in the dub, "Why do people always apologize for something they can't control?" It's a bit ironic in this circumstance seeing as he feels a sense of weakness and remorse for Koyuki's demonification, but this was out of his hands.
fight scenes aren't really my forte and the placements of Hakuji and Koyuki matter here. Hakuji could be a Hashira and Koyuki an Upper Moon (maybe UPM3 for obvious literary reasons); Hakuji could be a Kinoe (I could see him being exceptionally talented) and Koyuki being just another demon. I leave this up to you, anon. ❤️
short nsfw part below
i don’t read or write angsty sex often but I'm definitely not a hater!
if Koyuki was a demon but stayed by Hakuji's side like Nezuko, then I could see them attempting to have a sex life as they still desire one another!
however, if we go the other route, then it's hard to see or write a situation where angsty sex can happen between the two but it's not impossible! there's a chance that Koyuki (assuming that Muzan took her memories) mistakes Hakuji as another victim and he pretends to be a fool in order to get close to Koyuki after not seeing her for so long. yet, if Koyuki were to catch him red-handed, it could end up in another fight to the death or she runs away.
to be honest, I would imagine Koyuki's abilities to be Akaza's opposite in which Akaza is offense heavy whereas Koyuki is more defensive. Koyuki was very weak in her human life, and her demon life, you could write that she has gained physical strength but it's definitely a strength of an Upper Moon. I've thought of many variations of Koyuki's blood demon art, and i think it would be cool if her blood emits this scent that can paralyze someone if they inhale it (similar to Tamayo's ig you could say).
I'd be down to try writing one, anon! also, thank you so much for interacting with me! i know this account might seem dead so I'm sorry, but your ask means a lot to me ❤️
