Mahito

TW: slight NSFW, degradation, dehumanization, Stockholm Syndrome, Mahito in and of himself, platonic to romantic yandere

Mahito makes it a point to treat you like an animal – his human pet.

Ever since he first took you. The cage, the collar, the petting, and the treats.

Most of the time, when he talks to you, he acts as though you’re incapable of understanding complex conversation, using only a few words and simple commands – a smile stretching his face, stroking your head when you do good. Other times, he acts as though he’s forgotten you can even speak at all. The worst part is – you don’t really know whether he’s faking or not.

He takes you for walks and plays with you – letting you off the leash for a game of hide´n´seek in the forest where he chases you down barefoot – he doesn’t really care about the rules or that he’s breaking the basic premise of the game. He just laughs, liking the way you pant and wince against the mossy floor after he’s hunted and tackled you down for the umpteenth time, sweaty while you beg him to take you home with teary eyes and puffy cheeks. Home – being where he keeps you.

You used to refuse, you used to run away and fight him when he caught you – with scratching and clawing and biting and barking, but you soon learned to behave. He told you he had no use for rabid pets and threatened you with transfiguration, warning you not to bore him, and ultimately – after having seen him twist enough people into mockeries – you stopped doing much more than obey.

You’re constantly blue with bruises and stinging from scratches – but you wash in the hot springs when Mahito brings you along – soaking your aching muscles in the warmth while he cheats in playing Marco Polo, sneaking a peak and tagging you with a laugh – awfully resembling that of a child. You swear you often have to shake the feeling of mothering him out of your head before doing something regrettable.

Other times, he’ll take you to the beach. You asked him once how it was possible, but he’d just booped your nose with a smile and told you it was something you wouldn’t be able to wrap your little head around – and, looking towards the horizon of the never-ending sea, inside what you could have sworn was a concrete building, you couldn’t help but agree with him.

Sometimes you see his friends and hide behind him. He thinks it funny and excuses you, laughing out that you’re shy. And you suppose he’s right.

You used to be shy around him, too. You don’t know when you accepted it – being his pet.

Lately, he’s been inviting you to sleep with him in his hammock instead of your cage. And everything except your left brain betrays you as you lie snug against his side, with his arm softly holding you around your midriff. He’s so warm, and your whole body feels cottony at the pleasantness of another’s embrace after having gone so long without it. Actually, you almost cry, resting your head atop the rise and fall of his chest, closing your eyes to the steady beat of his heart thumping just beneath your ear. In the moment, you even forget he isn’t human. It just feels nice.

You don’t even mind when he dances his fingers up your arm in ticklish touches. Instead, you nuzzle into him with something so vulnerable as a moan leaving your lips.

His eyes travel from reading the pages of his book to the blissful look on your face and the way your smaller hand grips his tunic – but he doesn’t make much of it aside from raising a brow.

He’s seen scenes like this at the theatre – sappy love stories Junpei used to cry his eyes out over – awkward teenagers in dark silent bedrooms and clothes on the floor, then kisses and hugs and naked flesh and sweat and heavy breaths and moaning. He can’t deny it makes him curious despite never having felt any personal need to truly understand any of it. It's a human thing after all.

Your warmth makes him wonder, though. He’s always enjoyed the soft feel of your skin on his fingertips, whether you’re trembling or not – it has an interesting texture – warm and doughy. He could imagine it would feel good pressed against his body, too.

Without a word, he tugs your shirt up your torso, pulling on it until you raise your arms and allow him to remove it entirely. You became a little tense then, hiding your naked chest from him by folding your arms.

He takes off his tunic just as casually, and you don’t understand it, but suddenly you feel a little blushy. But you don’t say anything – almost as though you’ve forgotten you can speak just the way he pretends.

His skin’s ashen and pale – but his torso is just like a normal guy’s – toned with muscles, two nipples, and a belly button. Oh, and stitches. Like a patchwork.

He lifts his arm, and you take the cue, laying down again – now skin to skin. He’s even warmer now, you note – and something about the feel of bare skin makes your head hot. And you can't help how that heat spreads between your thighs – but you keep it to yourself.

He lifts his book and begins reading it again, turning the pages with the same hand he holds it up with. But his free hand travels from resting on your hip to your chest.

You suppress a shudder by biting your lip, and he cups your tit with absentminded curiosity – paying you not a glance while his eyes lazily skim the words in front of him, giving your breast a firm squeeze.

He keeps track of your small shufflings despite you trying to keep them to yourself – charting what touches elicit your reactions. Soon, he finds your nipple, feeling it stiffen with yearning beneath his thumb, pushing it like a button only for it to bud out again. You stifle a sound he hasn’t heard from you before.

He reads his book finished, then lets it drop flat on the floor beneath you. His statement is like a resolution. “Let’s play a new game.”

You peek up at him from the nook of his arm. “Game?” You ask, but he's already maneuvering your body despite it causing an unsteady swing in the hammock.

He ignores both it and your question. Giving you those very curt commands one would say to a trained pet. “Up on my lap.”

You follow. “Okay-”

You’re straddling him next. Bare-chested while he lifts both hands to cup each tit.

You’re fully flushed now, face steadily getting dewy from the heat as you look away – bowing your head off to the side with your teeth sunk into your lip.

He’s playing. Groping the pillows with fingers now swallowed in the fat before releasing again, twisting the perky nips with eyes feeling a little foggy at the sight. His mouth suddenly waters, thinking about how it looks as though they were made to be eaten – no, not eaten exactly, but something else, something similar...

Indulging the thought, he leans in and envelopes the sensitive things between his lips, sucking on them with his warm wet tongue circling and flicking the point.

Old instincts resurface at the pleasant feeling and you grind your hips down on his lap without thinking.

He falls victim to it, too – taking your hips in both hands while grinding whatever it is that’s gaining weight between his thighs up into that place between yours.

The feeling is more than nice, forcing his entire body to be both mellow and tense with a hunger for more all at the same time.

He presses his face entirely against your chest, nuzzling between the soft mounds there with his cheek. Hands slipping from your hips to pull you closer and grind you harder down on his lap, slithering his arms around the small of your back and hugging you hard.

And you don’t want to think about how fucked up it is when you need it so badly – rolling your hips down, riding that bump you feel nudged against your crotch – like it's the only source of comfort you've had for months. You think about its size – it feels big – you can’t help but picture it – long and pale, probably with a curve and a sharp spine – fuck, you need it – want it pounding your guts, want his pelvis slapping against your clit as his fat cock shoves against your womb – filling you up with thick and filthy warmth-

You still with a shudder when you climax, breaths heavy and shaky. In the blind chase, you’d caressed his head and held it to your chest like a lover would, hugging him close with your body pressed flat against him.

He’s also panting, hot and damp huffs dewy against your skin.

There's something sticky in his pants… and he could have sworn your souls had merged there for a moment...

He’s never felt that before.

Flies in Honey

Mahito/Reader/Yuji Word count 3K

Warnings: DEAD DOVE DO NOT EAT, EXTREME NONCON, mIndbreak, character death (reader insert)/ You’re already dead prior to this fic, Mahito uses your body, Mahito is his own warning, humiliation, victim blaming, profanity.

Aged up characters. Spoilers for jjk S2. Consider this an Au where Todo dies and Yuji loses against Mahito.

Yuji doesn’t know how he got here.

It's dark, and damp, wherever he is. It soaks into the rags of his clothes and his exposed skin, gravel tearing at his back. He hardly feels it.

The cracks on the ceiling fissure and twist together, but he’d rather look at them. It's better to look above him than what lies before him.

He’s wearing your face.

Above him, you sigh, breathy and high pitched, Your hips roll into his, and Yuji bites back a hiss. His hands lay limp at his sides.

“Why aren't you saying anything? I thought you would like this.” Your voice is wrong, you’re talking with his voice and Yuji feels the bile rise in his throat.

You switch rhythm, and Yuji chokes on his spit as you bounce up and down his cock. His hands spasm into claws, but no, he doesn't touch you. He won't, he won't.

You laugh. It's so fucked up but he sounds like you.

“You like this better, right?“

“Fuck you–” It was a bad idea to talk. Your– Mahito's hand shoots out and he sticks three fingers into his open mouth to gag him. Two on his tongue, the other on the roof of his mouth, keeping his mouth open. He chokes, but Mahito presses down on his tongue.

He’s going to come again. What number was this? He lost count around the fourth. All he could focus on was the hot coil in his belly, the tightening of his balls and that horrible fucking sound of your warped laughter when he spills, again.

It shouldn’t feel this good. He wants to tear his fucking skin off. He wants to bite down on the fingers in his mouth, he wants to curl into a ball and never wake up.

He's not going to admit to himself he's enjoying this, that he's missed this. It's not you. You're dead. You died, and it's Yuji's fault. All of it is. He got to you, and now he's wearing your likeness like it's a new coat, the bitch.

But damn, it really looks like you.

“I memorized everything about her, you know.” Your fingers leave his mouth, punched out gasps leave his chest while hands drag down his skin, drawing red lines.

“She was fun to play with. Stubborn too. Kept fighting even when I made her unable to,” he giggles.

“But she made the prettiest sounds when she finally broke. Prettier when we slept together too. She was just like you–Human. Always trying to deny yourselves at your most desperate, out of some half formed sense of dignity. See?” He presses down with your body, chest to chest while your walls flutter around him. Yuji’s eyes roll back, his hands leave bloody gorges in the ground.

“But human dignity is just the same as human depravity; you can't hide your baser instincts even in the worst circumstances, huh?”

Yuji would fight back, but his head is swimming, and his bones feel like they’re replaced with jello. There is a rage that simmers as he talks though, and Yuji bites his tongue until he tastes iron. It drips through the hole in his cheek. Mahito sees this and sighs.

"Your base instinct is to kill me. My base instinct is to murder your soul. That's what this is." He gestures between the two of them, not breaking pace. His hand drifts down, and he wipes away at the blood on his face, though he only succeeds in smudging it more.

“I did the same thing to her. Took your face and made her tell me how to do it right.”

“You’re sick–”

“I consider myself considerate. It's why you’re here and not dead.” He stops moving, tilts his head and meets Yuji's eyes in an eerie stare you've never given him. “Did you know that was my first time? I liked it.” You, fuck, he tilts your head, eyes pointed up in thought.

“Well, I'm a ‘human curse’ so I guess of course I would.”

“You fucking–” This time Yuji tries to buck him off, get some room in between them to get a hit in, but all he accomplishes is Mahito pushing him down and pinning his hands, going back to his earlier motions. Yuji's weaker now. Maybe its because its your face. He could never fight against you, even while sparring.

“That's how–I was able to memorize it too. All her faces, her sounds, what she likes. I wanted to understand you, through her. And now," a sound, high pitched and miserable leaves Yuji's throat.

"You like it too, right? A perfect replica, right? Wanna keep going?” Yuji just shakes his head, and tries to fight off his grip. But Mahito has more hands, and he remains pinned. He can't help the slight bucking of his hips, and when he notices, Mahito grins, a ruddy flush spreading across your face in a bald faced insult.

He can't breathe. He needs to vomit.

You had gone missing weeks ago, called on a mission to deal with a second grade level curse. Nothing too hard for you, it was a quick job and everyone had thought that you’d be in and out.

But cursed spirits have been acting strange lately, and everyone simply thought that it was due to the encroaching Halloween date. Due to various thoughts and practices towards the day, this was normal. But you had gone missing and the only sign of your whereabouts came from another encounter with the patchwork curse.

He went down to the sewers with Mr.Nanami, following the smallest clues they had towards your disappearance, where they met Patchwork. He had been vague and leering and lewd, and it was the first time Yuji saw Mr. Nanami’s face twist into such visceral rage. He mirrored the feeling, but Mahito had escaped, along with any other clues to where you were.

He had tossed a lump of...something to Yuji with a mocking grin, spongy and pale. They took it back to Miss Shoko, and it was confirmed to be a piece of your brain matter. Your death was confirmed.

Hope had dragged him along, weary and spitting blood, but losing you…was too much. Shibuya. Nanami, Kugisaki, Todo, you… His mind broke. He could feel the cracks. They fought, Mahito had knocked him unconscious, and dragged him to god knows where, and now he’s here.

And now he was faced with this horrible caricature of you, with too wide eyes and a leering grin that reminded him exactly of who was wearing your face.

Mahito didn't even seem that interested in the sex, too busy staring at the way Yuji reacted. His muscle spasms, the way he would jerk away from his touch or forward when he couldn't help it, the blank look on his face that sometimes twisted into an expression of such utter loathing– Or lust, and then his face would twist with such despair, a broken sob dragged from behind his clenched teeth, wrangled and bloody. Mahito felt the dark glee drip honey sweet through his soul, like the slick that ran down his thighs.

You really were a fun experiment. He knew how much you meant to Yuji, and initially just wanted to use you to damage his soul further. But where was the fun with that? You were something special. Yuji Itadori had plenty of friends and mentors, and killing any random person in front of him would always garner the same effect. But there was only one you. He wanted to understand you, and the exact place you held in Itadori’s life.

What made you special? What made you stand out to the one person, his natural enemy? Humans and their romantic relationships always seemed like a Greek tragedy to Mahito; Of course the person you let know all your weaknesses would be the one to destroy you in the end. Love always gave rise to hatred. It gave rise to a particular brand of hatred that made up Mahito, and if he was anything, he was always curious to know the full substance of his soul. That's where you came in.

“We would talk, and I'd have her tell me all about you–” Mahito drawled. “I had to pry out all the other stuff but she eventually spilled. I wanted to know everything you see,” he punctuates his words by slowly pulling himself off of Yuji's cock, before dropping down with a slap of flesh. He watches in fascination as Yuji’s lower belly flutters.

“We made deals the other half of the time. A few less experiments if she talked, or let me touch her.”

“I’m going to fucking kill you–”

“I got bored eventually, after she told me everything, and I took everything I could... I don't even remember what I did to her in the end."

Mahito wondered, if love gave rise to hatred, would you hate your lover for not rescuing you? Or for being the true target of Mahito's morbid intrigue? He never got his answer, you never voiced any thoughts like that, and strangely, he sensed no hatred at all when you died. Not for Yuji, or even for himself. You were probably too broken.

Mahito shrugged. “Oh well. She’s dead now anyways.” An ugly, violent sound tears through Yuji’s throat, and finally his hands reach out to grab at his–your waist with a bruising grip. He shoots up and doesn't let Mahito move, and Mahito is curious about this reaction, so he waits while Yuji catches his breath.

“You…how can you…just do that to people? She never did–she never did anything wrong–” His head comes to rest on your collarbone, and Mahito watches this all play out with an intense curiosity, and a growing glee.

Yuji continues to break down, tears slipping from his eyes down to the soft flesh of your breast.

“What the fuck did you do to her…why the fuck did you take her…" Mahito sighs, lets the familiar timber of your voice take over, and drags a hand through Yuji’s hair. Not as gentle a touch as he made you demonstrate on him, but Yuji shudders, and burrows further into the mimicry.

“Yuji.” At the sound of our voice, your true voice, Yuji's shoulders shake horribly.

So this is grief? Or despair? Mahito remarks. What's the difference? He watches Yuji as he shatters. Yuji sobs, ugly and loud off the sewer walls when Mahito starts moving again, but his hips thrust shallowly into your slick cunt.

Mahito wondered, had wondered, if love gave rise to hatred, then you just needed to love him, right? If he wanted to understand your place in his enemy's life, your place as his 'lover', than you just had to love him, right? And lovers do things together, they talk about their vulnerabilities, they watch and learn their tics and preferences and dislikes and habits. They stick through the good and bad. And Mahito was….bad.

Yuji continues to sob, but he tilts his head back and starts fucking him back, soft whimpers slipping past his bitten lips.

“I’m sorry, I’m so damn sorry, ah–! Fuck, I'm sorry, I wasn't there, I let him get to you, fuck I’m sorry I let him hurt you–”

This isn’t even about the sex. But Mahito is a disaster curse–he was born from hate. And hate has flavors. Rage, vindictiveness, envy, glee; he’s all of them. And the hatred rising from Yuji Itadori is so potent and despair riddled that Mahito sighs, and in an act unbidden comes with a choked out gasp.

Its sudden. Mahito hasn't orgasmed once this entire ordeal before, but as soon as he does, Yuji groans, deep and guttural. His head flops back to the hard ground, and immediately his gasps turn shallow and fast before he pulls your hips down and comes in thick, hot ropes.

Is it because Mahito is wearing your face, or did he always hold on this tightly to you? Mahito is sure he’ll see dark purple bruises on your skin when he lets go, and Mahito decides he’ll keep them. He’s never fixed you, after all, so bruises were a common sight. He just wonders how it’ll look as it ‘heals’. Maybe Yuji could give him some pointers on the visual front.

Yuji lays there, and cries. The tears cut clean streaks through the blood and dirt and grime, and Mahito stares, and he stares. His pink hair is flat, and stringy with dried blood.

"Why are you pretending you don't like this?"

"What...?"

he tilts your head. "Its sex. Even if you're not one for carnal pleasure I still look like her. I still feel like her. Don't you love her?"

"No...I--"

"You dont?"

"I do, you're just--! Fuck, get off of me--" Mahito swats his hands away, almost halfheartedly, clicks his tongue.

"If you did 'love her' than wouldn't you stop me already? I read a plot like this in a book once... Shouldn't you kill me for 'defiling her memory' or something? You're enjoying this."

"I'm not--"

"You are."

"I'm--"

"You are. Stop denying it. I'm not going to stop if that's what you're scared of." Mahito chuckles.

“What the fuck…is your problem, what do you want?” Yuji gasps out. His breaths are shallow and his voice is high patched, chest rising up and down, up and down, too fast. He runs his thumb over his collarbone if only to feel the rabbit-fast pulse.

“What do I want...?”

“Why me? Why do you want to break me? ‘Natural enemy?' I don't even know what that means...” Mahito is silent for a moment longer, enjoying the moment, before he leans over. With the use of Idle transfiguration, your mangled face takes up Yuji’s vision, and he feels the breath die in his throat.

“You are my natural enemy Yuji Itadori. But I can't kill you. Physically, that is. So this is the next best thing.”

“You, I–”

“Don't take my words too seriously, I am a curse after all,” Mahito brushes your hair out his face and leers.

“But you seem to think that this is a punishment. This is a reward, Itadori.”

“‘Reward’?” He hiccups.

Mahito nods.

“Without you, I would have never gotten to understand my soul on such an intimate level. I know the essence of my soul because of you.” He leans closer, breath full of mirth and rot.

“And I thought, surely you missed your little girlfriend. And isn't intercourse the most sacred act between two lovers?” Mahito shrugs.

“An experiment for me on whether this would fully break you or not. You can consider it a gift though.”

“You think…you think I want to see her like this?”

“Yes?”

“No!”

“Then would you like to see what's left of her?” Mahito points back to the mouth of the sewer. Tortured, anguish moans rise from there, and Yuji can already guess what was there. Despair grips his heart and rips it out.

“Don't worry, I didn't tranfigure her, actually. I bet I can find the parts of her around somewhere …but only if you ask nicely.” Again, he thrashes, but from battle, or loss, he’s weak.

No, Yuji knows why. He could never raise a hand against that face. Even now, seeing dark purple bruises on a body that even resembles yours makes guilt curl in his chest.

“Get off of me."

“What was that? You're talking so low I can't hear you.”

“Get off of me!” Mahito drawls out a low note, but surprisingly, he does as he’s told. Yuji hisses as he slides off his dick, letting him feel the drag of your walls and how they flutter. It's familiar, and Yuji wants to kill something when he thinks of how this curse must have learnt that from you.

He wants to kill himself when his breath hitches at the feeling.

Mahito gets off, but does not release his hands. The image of an extra pair of hands holding him down creates enough clarity for him to differentiate between the two of you, and Itadori growls under his breath.

Your face smiles down at him, and Itadori tries not to stare back. Just like that, the anger is gone. He’s missed you, after all.

“...You know I'm getting out of here, right?”

“And you’ll try killing me. I know. That's if you don't come back for this, though.” He gestures with a stitched hand the bare curves of your body.

“You’ve killed my puppets, transfigured humans, even the kid ones! Shibuya didn't break you, killing Mister 7:3 didn't break you, or that Gorilla, that hammer woman’s death almost did… but something tells me…”

He slithers up and slots himself against Yuji’s side, and it's an ingrained habit to hold you. He jolts back quickly enough in horror, but Mahito grabs his arms, and keeps them on him.

“Killing me while wearing this face would really shatter you, hm? it's why you didn't stop me when I dragged you here and did what I did. You let me. You let this happen." He shakes his head even before you, fuck, it's done. He denies it, because what else could he do?

Mahito moves to hiss in his ear.

"Is it because of guilt? You're so human, Itadori Yuji.” And his eyes switch to that familiar silver and blue.

“Even if it's self loathing, I can still sense it. That hatred. You’ll come back, and I'll break your soul down some more each time. Little by little…until eventually, one of us kills the other. That's how this is going to go.” He rests your head on his shoulder, listening to the dull drag of his heart. The movement is so familiar that Yuji could cry again, but he holds it back.

“....So that's how it is.”

“Yup. Oh, and I'm still waiting for my thank you.”

“....”

He sits up, and laughs at the way Yuji’s eyes go pinprick small, copying your laughter down to a terrifying degree. Yuji doesn't know how, he’s sure you never laughed in a place like this.

“Hate me all you want, it only makes me stronger. But, even if it's unconventional, I still let you see her, feel her. I want a thank you for that.”

And Yuji must truly be broken because what if I really never see her again? What if I never hear her voice or touch her? This here, horrible as it was, was both knife and balm, like peroxide on an open wound. Cleansing and burning.

“....”

“Well?”

If…he just pretends it was you, if he just watches your mouth and imagines….

He used to thank you after sex in the beginning, before you told him to stop thanking you like you were being paid to sleep with him. Of course, this led to the private joke, where you would demand your payment–anytime, anywhere, and he would smother you in kisses. Fushiguro, Kugisaki and even Gojo-san would roll their eyes or tease or gag, but he loved it. He knew you did too, with how often you used the joke.

“...Thank you.”

Fuck, he misses you.

“Nuh uh uh! Not like that!” Mahito shoots up, hovering your face over his again, noses touching. He switches his eyes back for yours, extra arms gone.

“Thank her. Like you used to. Go on.” He's broken. Yuji is broken.

He reaches a hand and cups the side of your face like he used to. You cant into it like a cat, and a fondness rises in his chest, just to be awashed by despair. He has to clear his throat, and still his voice breaks.

“Th-Thank you...” And because he can't help the fact that it's you, it looks just like you, he pulls you down for a kiss. It's so familiar, down to the way you would tilt your head to the side, and your tongue would swipe over the bottom of his lip. But Mahito bites down, reopening a wound from when he bit his tongue earlier. Blood fills his mouth, but Mahito laps it up. His tongue pokes at the hole in his cheek.

He pulls away, and his eyes are still yours, warm and loving, red smeared at the corner of your mouth. He smiles your smile. He speaks in your voice. Soft, so soft it kills him.

“You’re welcome, Yuji.”
