HEAR ME OUT

Aventurine and his partner have been together for a while when they somehow try working through Aventurine’s past trauma by showing him what a true master is like (reader)

Note - heavy bdsm, master/slave, anything else you’d like but I would prefer this being a healthier one so not non/con or forced

Thank you! 💖💖

The room was quiet.

Not sterile. Not cold. It smelled faintly of lavender and wax polish—warm light spilling from a shaded lamp. The blinds were drawn. The door was locked.

Aventurine stood in the center of the room like a model in a glass case, posed. Perfect. Still. He had removed his gloves first. Then his rings. Then his coat. Every motion methodical. Almost clinical.

You’d seen him negotiate with CEOs more relaxed than this.

You sat on the edge of the couch, legs slightly parted, arms resting on your knees, watching him like he was something fragile. Not in the way that meant he’d break—but in the way that meant he already had, at some point, and learned to glue himself together into someone flawless.

And he was flawless. That was the problem.

"You're not breathing," you said quietly.

Aventurine blinked. Then inhaled like he forgot that he needed to. A short, clipped breath. He forced a smile. "I'm just… preparing."

"For what?"

He paused. "To give you what you want."

You let that sit. Let him feel it.

Then you stood—slow, controlled—and stepped into his space.

"Look at me."

He did. Carefully. He always looked carefully, like his gaze was a scalpel and he was afraid to cut too deep.

You reached out, brushing your knuckles against his jaw. He didn’t lean into it. He didn’t flinch either. He simply absorbed the touch like it was something he had to endure—an input to be processed, not felt.

“I want you to listen,” you said. “And I want you to listen as Aventurine. Not as someone performing. Not as a client trying to impress me. As you.”

His throat worked as he swallowed. “…I’m listening.”

“I’m not asking you to submit because I want to dominate you.”

He stiffened.

“I’m asking you to submit because I want to keep you safe.”

A silence followed. Longer this time.

You let your hand fall from his jaw and gently, deliberately, took his hand in yours. You turned it palm-up—his fingers were smooth, trembling ever so slightly.

You pressed a kiss to the inside of his wrist.

“That’s the only reason,” you said. “Everything else—the commands, the structure, the rules… those are tools. Not punishments. Not games. They're ways to show you something you weren’t allowed to believe.”

He stared at you, eyes flickering. “Which is?”

“That being owned can feel like being protected.”

His lips parted—then closed again. He didn’t speak.

But he was still listening.

So you guided him to the couch. You sat down first, then tugged him forward by the hand until he was kneeling between your legs. Not to humble him—to center him.

"Now," you murmured, letting your fingers brush along his throat. “Let’s make something clear before we go further.”

Aventurine swallowed again. You felt it beneath your fingertips.

"You are mine only if you choose to be. And that choice doesn’t disappear just because you're in a collar or calling me Master."

His breath hitched. Slightly.

"You have a safeword. And you will use it."

You felt him tense—but it wasn’t fear. It was confusion.

“Why?” he asked softly. “Do you think I’ll regret it?”

“No,” you said. “I think someone else made you believe you weren’t allowed to.”

He froze.

And there it was.

That flicker. That twitch beneath the surface. You saw it behind his eyes—how he wanted to deflect, wanted to throw on that trademark smirk and laugh you off, pretend none of it reached him.

But it did.

Because the first time you called him "slave," he hadn’t flinched. But he hadn’t melted either. He had looked like someone waiting to be hurt. Obedient, yes—but not present.

You didn’t want that again.

“I don’t want obedience like that,” you whispered.

His lashes flicked up. His eyes were wet—but not crying.

You kissed the space between his brows. “I want your devotion. Your trust. Not your fear.”

He went still.

“…Then I don’t know how to be yours,” he said softly.

You tilted his chin up.

“That’s okay,” you said. “I’ll teach you.”

　　　　　　　　　　　　　　𓆩♡𓆪

The collar was black. Supple leather, lined in deep velvet. Not flashy. Not harsh. Nothing sharp or ornamental. It wasn’t a trophy. It was a promise.

You fastened it slowly around Aventurine’s throat, adjusting the buckle until it sat snug against his skin, resting in the hollow between his collarbones. His breathing had grown shallower with every click, every brush of your fingers. But he didn’t pull away.

He didn’t stop you.

And now—now he knelt.

He looked beautiful like that. Not just in the aesthetic sense, though he always had a way of appearing curated, even when undone. No—this was deeper. He looked like something offered.

The room was low-lit. Heavy drapes. No mirrors. No performance. Just you and him, framed in candlelight and silence. Your voice was the only thing allowed to break it.

“You’re trembling.”

His eyes flicked up, fast. Shame tightening his jaw before he could stop it.

“I’m not—”

“You are,” you said gently. “And that’s okay.”

He exhaled like the air had been trapped in his chest for years.

You reached out, brushing his hair from his forehead, slow. He didn’t lean into it, but he didn’t pull back. Still learning. Still testing the depth of the space you’d carved open between you.

“I want to hear you say your safeword.”

“…Now?”

“Yes.”

His lips parted, then closed again. A flicker of pride, of resistance. Not defiance—just fear dressed in finery.

You tilted his chin up, thumb dragging along the edge of his jaw.

“Say it for me, Aventurine.”

“…Citrine.”

The word hung in the air. Soft. Almost delicate. Like it didn’t belong in his mouth.

“Good,” you murmured. “That word is power. Not weakness.”

You saw it flash in his eyes. That old wiring. That ache. The way he’d been taught that power only came through performance or control, through being sharper, cleverer, faster.

And now here you were, asking him to surrender.

You reached for his shirt. Silk, crisp, fitted. The kind of thing he wore like a second skin. You undid the buttons slowly, not ripping or demanding, but unwrapping him like something valuable. Something earned.

By the time you slid it off his shoulders, his breath had quickened again.

“Color?” you asked softly.

He blinked. “Huh?”

You smiled. “Give me your color.”

“…Green.”

Safe. Uncertain, but safe.

You trailed your fingers down his chest—bare, smooth, too still.

“I want to see you move when I touch you. Not freeze.”

He swallowed hard.

You leaned in, lips brushing just beneath his ear. “You don’t have to be perfect here. You just have to be mine.”

He shivered.

“…Yes, Master.”

There it was. That subtle quake beneath the surface. Not fear. Relief.

You reached for the tie you’d laid on the bed earlier—rich crimson silk, soft and long. A blindfold, if needed. A restraint, if wanted. But tonight, just a tether. You looped it gently around his wrists behind his back—not tight. Just a suggestion.

“Sit back on your heels.”

He obeyed.

You let the silence stretch, letting him feel the leash of your presence even without a word. Your gaze burned into him—watching the way his chest rose and fell too fast, the way his fingers twitched behind him, even restrained.

Then you spoke. Low. Commanding. Steady.

“Say it.”

He blinked, caught off guard. “Say… what?”

“Who you are.”

His throat bobbed.

You took a step forward, letting your fingers trail beneath the collar at his throat.

“Say it, Aventurine. Who do you belong to?”

“…You.”

“That’s not enough.”

He shuddered.

“I belong to you,” he whispered. “I’m… I’m your slave.”

The words cracked on the edge of something old—something raw.

And you knew. That this wasn’t the first time he’d said it. But it was the first time he wasn’t punished for saying it wrong. The first time he wasn’t being used like a toy to be broken and left behind.

This was the first time he said it and wasn’t afraid.

You stepped around him slowly, trailing your hand across his bare shoulder as you did.

“You’re mine,” you said, voice smooth as heat. “Because you asked to be. Because I said yes. And now… I’m going to show you what that means.”

You stopped behind him, let your hand drop lower, brushing the curve of his spine.

“You’re going to listen.”

Your hand slid lower—over the waistband of his slacks, down to his thigh.

“You’re going to obey.”

You knelt beside him now, brushing your lips over his temple.

“And if I touch you and you shake, I’ll hold you.”

He let out a small sound—too raw to name. You felt his breath stutter. His entire body leaned just slightly into yours. Like the tension in his shoulders had finally started to give.

“Color?” you asked, voice warm.

“…Green,” he whispered.

You smiled.

“Good slave.”

His eyes fluttered shut. His lips parted. And for the first time since you’d collared him, Aventurine didn’t look composed.

He looked free.

　　　　　　　　　　　　　　𓆩♡𓆪

You guided him onto the bed slowly. Not forced. Not posed. You didn’t bend him—you invited him. And he followed.

The sheets were dark—deep maroon silk, soft enough to slide against bare skin without a sound. The collar caught the light in a subtle gleam as Aventurine lowered himself down, legs folded beneath him, arms still behind his back. You sat in front of him, letting the room fall to quiet.

He was breathing a little too fast again.

You reached out, cupping his jaw in one hand. His lashes fluttered.

“Color?”

“…Green,” he whispered.

Your thumb stroked his cheek. “You’re doing beautifully, treasure.”

His breath hitched again, this time from something that almost sounded like relief.

You leaned in and kissed him. Soft. Just once. And when you pulled away, you saw the dazed flicker in his eyes.

You didn’t ask for more yet. You just started touching him—slow strokes of your fingers over his chest, his arms, his thighs. Mapping. Worshipping. Letting him feel like something sacred.

“You’ve been holding yourself together for so long,” you murmured, tracing the hollow of his hipbone. “You don’t have to anymore.”

Aventurine’s body twitched under your touch, heat flashing across his face. He was already hard—aching against the front of his slacks, pulse pounding through him in quiet, desperate waves.

You kissed his collarbone, then lower. “I want to see what you look like when you come apart.”

He made a noise—small, breathy.

“I want to see how messy I can make you.”

Another whimper. This one sharper.

You undid the button on his slacks. Pulled the zipper down with slow, steady fingers.

"You’ve kept yourself so clean," you said. "So controlled."

You slid his pants down, along with his briefs. His cock sprang free, flushed red, already leaking.

"But this isn’t clean," you whispered, wrapping your hand around the base. “This is filthy. Needy. And it belongs to me.”

He shivered violently. You felt his knees twitch beneath him.

“You’re mine, Aventurine.”

He nodded. “Y-Yes, Master.”

You pumped him slowly—light pressure, thumb teasing over the slit. You kissed down his thigh as you worked, feeling the tension begin to fracture.

"That’s it," you whispered, lips brushing his inner thigh. “Breathe for me, pretty boy.”

He did. He tried. He was panting now, head tilted back, fingers clenched behind him like he didn’t know where else to hold the sensation.

“Such a good thing,” you crooned. “So obedient. So sweet. So ready to break.”

Your tongue flicked over the tip. He jerked—gasped.

"Color?" you murmured against him.

“…Green,” he rasped. “F-fuck—green—”

You hummed in approval, then dragged your tongue up his shaft, slow, tasting every drop he’d spilled.

"Look at you," you whispered, mouth just above his cock. "So wet already. You’d let me ruin you with just my tongue, wouldn’t you?"

He moaned—loud.

So you took him in. Not all the way. Just the head. Just enough to pull a shudder from his hips before you pulled off again.

“Not yet,” you murmured, hand stroking him again, firmer. “You don’t get to cum until you beg.”

You leaned up, lips brushing his ear.

“And not like a businessman,” you whispered. “Not like a negotiator. Like a whimpering little thing.”

His cock twitched in your fist.

"Say it."

“I—”

"Say what you are.”

“…Your p-pet,” he gasped.

You squeezed.

"Not good enough."

“I’m your—your toy—your slut—”

"Good," you growled. "Getting closer."

You tugged his head back by the collar, made him look at you.

"You’re mine, aren’t you?"

“Yes—yes, I’m yours—please, Master—please let me cum—"

And then he choked on a sound. His whole body jerked.

And the word fell from his lips:

“Yellow.”

You froze.

Not in fear. Not in failure.

In readiness.

Your hand left his cock instantly. You released the collar. Your voice softened.

“Hey.” You cupped his cheek. “You did perfect. You’re safe.”

His breathing was erratic. His eyes were glossy. But he wasn’t panicked. Not quite. Just too much. Overwhelmed. Drenched in sensations he’d never let himself feel before.

“I didn’t want to stop,” he said, voice breaking. “It just—just hit too fast—”

You nodded. Kissed his temple. Held his jaw steady.

“You did everything right,” you whispered. “I’m proud of you.”

He shivered. A small sound leaked from his throat—frustration. Shame. Something old.

You held him.

“You said yellow,” you murmured. “Not red. That means we slow down. We breathe. We check in.”

You reached for the silk tie around his wrists, undoing it gently.

He was trembling now.

And when he whispered, “I’m sorry,” you cut him off immediately.

“Don’t apologize,” you said. “Not for taking care of yourself. Not with me.”

He went quiet. Eyes searching yours.

“…So we can still—?”

You smiled.

“We’re going to continue. If you want to. And this time?”

You leaned in, kissed him slow, deep, open-mouthed.

“I want you to give me your surrender.”

　　　　　　　　　　　　　　𓆩♡𓆪

He was still shaking when you brought him back to the bed.

Not from fear. Not from regret. From how much it was.

He let you hold him without asking. Let you kiss the top of his head, run your fingers down the back of his neck, cradle him in your lap like something precious. And when your hand slid to his thigh again—he opened his legs without hesitation.

“I want you inside me,” he whispered. “Please.”

Your fingers traced the line of his inner thigh, featherlight. “You sure?”

His breath caught.

Then, “Yes, Master.”

You smiled, leaned in, and kissed the side of his mouth. “Then I’ll give you what no one else ever did.”

He blinked, eyes fluttering.

“What’s that?”

You kissed his throat, tongue dragging over the edge of the collar.

“Time.”

You laid him out like he was something sacred—chest to the sheets, legs parted, cheek resting against a silk pillow. He looked wrecked already. Hair wild, skin flushed, cock twitching against his stomach. He still had the collar on.

Your hand ran down his back slowly, fingers trailing the curve of his spine. You watched his hips twitch in anticipation.

And then you whispered, “I’m going to stretch you open now.”

Aventurine shuddered.

“Not like them,” you added, voice low and warm. “Not fast. Not hard. Not careless.”

You pressed a kiss to the small of his back.

“Like this.”

Your hand slid between his legs, parting them more. You took your time with the lube—warm, slick, worked between your fingers before you ever touched his hole. You let your thumb rest against the rim, not pushing, just being there.

“Breathe for me,” you whispered. “Color?”

“Green,” he rasped. “Fuck, I’m green—just—please.”

You slid one finger in. Slowly. No resistance. Just heat. Just a shaky, desperate moan beneath you.

“That’s it,” you murmured. “That’s my good boy.”

He gasped into the pillow, his whole body tensing—then softening.

"You're so tight," you praised. "So soft inside. You were made for this."

You curled your finger, watching the way he arched, hips twitching.

“M-Master—”

You hummed, kissing the dip of his back.

“I know. It’s good now, isn’t it?”

He nodded, whimpering.

You took your time. You didn’t rush the second finger. You didn’t stretch him to watch him squirm—you stretched him because you wanted him to be ready. You wanted to give his body the chance to welcome you.

Not endure you.

Aventurine was panting now. His cock leaked freely onto the sheets. Every twist of your fingers sent a sob through him.

“You’re doing so well,” you whispered. “Letting me open you. Letting me feel how warm you are inside. This hole is mine now, isn’t it?”

He moaned—wrecked, high, humiliated.

“Yes, Master—it’s yours—just yours—”

You slipped in a third finger, carefully, watching his back arch as he cried out.

But he didn’t say yellow.

He didn’t say stop.

He pushed back.

You grinned.

“Oh, you’re greedy now,” you murmured against his ear, one hand reaching around to grip his leaking cock. “You want it all, don’t you?”

He whimpered. Nodded. Twitched in your hand.

"Say it."

“P-please,” he sobbed. “Please fill me—break me—fuck me full—I want to be yours inside—please, I need your cock—”

You laughed—low, hot, proud.

“Oh, my sweet little slut.”

He gasped—choked on it.

You leaned down, kissed the back of his neck. Then whispered, “You like being called that now, don’t you?”

“…Y-yes—”

“You like being my toy. My slave. My obedient little hole.”

His whole body seized.

“F-fuck—!”

You pulled your fingers out—slow, careful, teasing.

He sobbed at the loss.

You lined yourself up, pressed the tip against his stretched, slick entrance.

He pushed back instantly.

"Greedy thing," you growled. "Beg for it."

“Please, Master—please—fuck me—ruin me—make me your cumdump—please—”

And you gave him exactly what he asked for.

You sank in.

All the way.

Slow. Measured. No brutality. No rush. You slid into him inch by inch, letting him feel it, letting him open around it, letting the stretch burn sweet and thick as your cock filled his aching hole.

Aventurine gasped—his voice a cracked moan as his body trembled beneath yours.

“Oh, f-fuck—” he choked out, knuckles white as they dug into the sheets.

You leaned down, one arm braced beside his head, the other gripping his hip tight, keeping him spread open as your cock bottomed out, balls resting snug against his skin.

“There it is,” you whispered into his ear. “Feel that? That’s me, inside you.”

He whimpered. You felt the clench around you—tight, slick, hungry.

“This is what you needed all along. Not a man who takes. A man who fucks you like he owns every inch.”

You pulled back—slowly—and thrust in again, long and deep, your cock dragging against the sweet spot that made his legs shake.

He moaned—loud, broken. His cock throbbed untouched against the sheets.

You kept the rhythm slow, heavy, grinding deep with every thrust, pushing the sound out of him with every roll of your hips.

“Y-you’re so deep,” he gasped. “I—I can feel you in my stomach—Master—please—”

You kissed his neck, teeth grazing the collar. “You’re taking it so well. My pretty little whore.”

He shuddered. “Yes—yes—call me that again—”

You thrust deep—he jerked, crying out.

“Say it.”

“I’m your whore,” he whimpered. “I’m your obedient whore—use me—please—just—”

He clenched around you, hole fluttering, walls pulsing like he was already about to cum.

You grabbed a fistful of his hair, pulling his head back.

“Don’t cum,” you growled into his ear. “Not until you break for me.”

Aventurine whined, a high, needy sound, mouth open, drool slipping down his chin as you kept fucking into him—slow, deep, deliberate.

“Faster,” he sobbed. “P-please—Master—please fuck me harder—need it—need you to ruin me—”

You slammed in hard. He screamed.

“Oh, that’s it,” you growled. “You like it now, don’t you? You like being fucked stupid.”

“Y-yes—yes, I do—please—don’t stop—”

You pulled the leash tighter, using it to anchor him as you began thrusting fast, hard, pounding into his slick hole until the slap of skin-on-skin echoed with every deep, bruising thrust.

“You gonna cum like this?” you hissed. “Face in the sheets, used, leaking, begging?”

“Yes—yes—I’m your cumslut—I’m yours—only yours—”

His words collapsed into gasping cries, voice breaking every time your cock slammed into that same aching spot deep inside.

You reached under him, fisted his cock—already wet, throbbing, twitching.

“You want to cum, slut?”

He nodded frantically, tears slipping down his cheeks.

“Then fucking ask.”

“Please—Master—please let me cum—let me make a mess for you—please—”

You grinned.

“Cum for me, slave.”

He screamed.

His body seized, hole clenching so tight around your cock it almost pushed you over the edge. His cum splattered across the sheets in thick, hot streaks, and he collapsed beneath you—shaking, moaning, drooling, trembling with every aftershock as you kept fucking him through it.

He was babbling now. You didn’t need to understand. It was all yours.

You growled low, thrusting one last time and spilling inside him, hot and thick, grinding deep as you filled him to the brim. He sobbed into the sheets—completely broken open, your cum leaking from his fluttering hole as he whispered, “Thank you, Master,” again and again.

You kissed his shoulder.

“You did so well for me,” you murmured. “So good. So obedient. So mine.”

He made a small sound—something close to a sob—but there was no fear in it.

Only peace.

　　　　　　　　　　　　　　𓆩♡𓆪

You didn’t let go of him. Not once. Not when he came undone under you, not when his body collapsed into aftershocks, not when his sobs started—quiet and broken, into the silk sheets.

You stayed inside him, shallow and warm, one hand on his waist, the other splayed across his chest. His breath came in shivers. His body twitched with every small pulse of aftershock, still spread open, still marked by you.

And still, he whispered, “Thank you, Master.” Over and over again. Like a prayer. Like a child afraid of silence.

You kissed the back of his neck. Gently. “You don’t have to thank me for not hurting you.”

His fingers curled in the sheets. He didn’t answer right away.

You pulled out slowly. Your cum dripped down the inside of his thighs, hot and wet, and he didn’t move. He just exhaled—long, cracked, like the last of his performance was melting out of him.

You left only briefly. Warm towel. Cloth. Water. When you returned, he hadn’t shifted.

He was still kneeling.

Silent.

Shaking.

You moved behind him and eased him into your lap. Chest to back. He folded like he’d been waiting to. You wrapped your arms around him and held him there—wet, ruined, open—and he let you.

You cleaned him gently. Slow, soft, reverent. Not possessive now. Not hungry. Just present.

“I want to hear your color,” you whispered.

“…Green,” he breathed. “Just… slow.”

“Slow is good.”

Another breath. Then, quieter: “I don’t want to go back to my room.”

“You won’t.”

You tightened the towel around him, pressing your palm over his heart. The leather collar was still warm under your fingers.

“Does this still feel good?” you asked, thumb brushing it.

“…Yes.”

“Does it still feel like a leash?”

“No.”

“Good.”

You tilted his face toward you. His eyes were red, wet, shining.

He swallowed.

“I kept waiting for it.”

You blinked. “For what?”

“For the part where you stopped asking,” he said. “Where you just… took.”

Your breath stilled.

He looked down, shame creeping like old blood into his voice. “They didn’t ask. Not after I was sold. The first ones just—”

You adjusted your hold—firmer now. Grounded.

“I know.”

“There was a man who called me by my serial number,” he said. “Said names were for people.”

You didn’t speak. You held him tighter.

“I used to think… if I offered it first, let people use me, I was in control. If I moaned loud enough or spread my legs fast enough, maybe they’d forget I didn’t want it.”

His voice cracked. His jaw clenched.

“But none of them ever stopped.”

You found his hand. Laced your fingers through his.

“…And you did.”

You didn’t say of course. You didn’t say I’m not like them.

You said: “You said yellow. So I slowed.”

And something inside him shattered.

He didn’t break pretty. He broke real. Face crumpling, shoulders shaking, tears falling hard against your skin as he buried his face in your chest and wept.

Not from shame.

From being seen.

You rocked him gently. Back and forth. Holding him through every sob, every tremor, every time he tried to apologize only to collapse again.

“I didn’t think I could ever be like this again,” he whispered.

“Like what?”

“Soft.”

You closed your eyes. Kissed his hair.

“You’re not soft. You’re just safe.”

His breath hitched.

“I don’t remember the last time I felt wanted,” he said, voice thin, “without needing to win something first.”

“You didn’t win me,” you murmured. “You let me hold you.”

His lashes fluttered. His voice dropped to a whisper:

“…Was I good?”

You cupped his cheek, thumb wiping a tear from his flushed skin.

“You were perfect.”

He laughed. It broke halfway. “I look pathetic right now.”

“No,” you said, smiling. “You look mine.”

He flinched—just slightly—but he didn’t deny it.

You kissed his nose. Brushed his damp hair back.

“Can I ask you something?”

“…Anything.”

“What do you want me to call you now?”

You didn’t rush it.

“You can keep Aventurine. Or Slave. Or…” You paused. “Kakavasha.”

He blinked.

His breath caught in his chest.

“I haven’t heard that name in so long,” he whispered. “It feels like it belongs to someone else.”

You nodded. “It does.”

He looked at you, startled.

You smiled.

“But maybe… that someone still lives here.” You placed your hand gently over his heart.

He didn’t answer. He couldn’t. His throat worked. His lashes fluttered.

You leaned close, nose to his cheek.

“Until you decide… I’ll call you what I see.”

He swallowed.

“And what’s that?” he whispered.

You kissed the edge of his collar.

“My beloved.”

hiii, I love ur writing, could u do a fic where Jason Todd is a mafia boss, and the male reader is his most loyal 'guard dog'? Jason literally treats him like one—giving him orders, rewarding him, keeping him close. Maybe there’s a moment where he calls male reader his 'dog,' and male reader just smirk and say, ‘Yeah? And who put the collar on me?’

thank u sm!

“BARK LIKE YOU WANT IT”

pairing. Sub!Mafia Boss!Jason Todd x Top!male reader

synopsis. In Gotham's underworld, Jason Todd holds the city by its throat. But every king has a dog at his heel—and M/n is loyal, brutal, and always watching. Jason calls him a mutt. But he forgets one thing—who put the collar on who? — 2.3k

warnings. Guard Dog AU, mdni, nsfw, amab reader, dubcon, possessive behavior, praise kink, degradation kink, minor physical restraint, mutual obsession, mafia politics, overstimulation, powerplay, collar kink, facefucking, blowjob, spitting, choking, humiliation, breeding kink, dirty talk, oral fixation, crying, subspace, manhandling, aftercare

Jason Todd ruled Gotham’s underground like it owed him blood. And in many ways—it did.

The Red Hood Syndicate didn’t move without his order. Rivals were ghosts before they made it to sunrise. Contracts vanished. Witnesses disappeared. And yet, for all the stories about Jason Todd’s brutality, his trigger temper, his high body count—

There was one man even the worst of the underworld feared more.

His shadow.

His guard dog.

You.

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

"You’re late."

Jason’s voice was sharp, not raised, but biting all the same as you stepped into his office, the double doors clicking shut behind you. You didn’t answer him. You never did when he was in one of his moods—irritable, pacing, hands stuffed into his pockets, a fresh line of blood drying down the corner of his jaw like he forgot to clean it off.

Or didn’t care.

He looked you up and down once. His mouth twisted slightly.

"You smell like smoke."

You stared, unbothered. "I burned a man alive in his own Porsche tonight. You wanted it done quiet."

He laughed. Dry. A little sharp around the edges.

“Messy job for quiet work.”

“Your note said ‘make it hurt.’ So I did.”

Jason stopped pacing. The city light from the penthouse windows caught across his eyes—green-blue, sharp as broken glass. He licked his lips once, slow. Then, “Come here.”

You didn’t hesitate.

Your boots echoed on the polished floor, each step solid. Intentional. Controlled. You moved like a weapon kept in a velvet box—danger tucked into civility, teeth beneath tailored suits.

Jason sat on the edge of his desk as you approached. Still calm. Still composed.

But his fingers twitched once where they gripped the edge of the wood. You saw it. You always did.

“You want to be praised?” he asked, tilting his head, voice half-daring.

"No." Your tone was even, flat, as you stopped in front of him. “I want you to stop testing me.”

Jason’s smile twitched. “But you’re so good when I do.”

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

It was like this. Always.

The tension. The push-pull.

He gave the orders. You obeyed. He treated you like property—his muscle, his executioner, his dog. And you let him.

But Jason, arrogant as he was, had always mistaken obedience for submission.

And that was going to cost him.

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

His hand lifted to your collar, two fingers brushing the sharp seam of your dress shirt. His knuckles grazed your throat, casual. Thoughtless.

But that’s where his control ended.

Your hand closed around his wrist.

His eyes jumped to yours, sharp with surprise—but not fear. Never fear.

“You like to call me your dog,” you said, low and measured. Your grip tightened just slightly—not enough to hurt, but enough to make him still. "Throw me scraps. Snap your fingers. Expect me to sit."

Jason’s breath hitched. Just a little.

Your voice dipped, threading a heat beneath the threat. "You like pretending I belong to you."

He didn’t speak. Didn’t need to. His mouth was parted, his pupils wide, and every inch of him was screaming yes.

"So let me ask you something, Todd." You leaned in, lips brushing the shell of his ear, voice dark with knowing.

"Who put the collar on me?"

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

Jason shivered.

It was subtle—but it was there.

The slow exhale. The twitch of his thigh muscles. The flush creeping into his neck that had nothing to do with anger and everything to do with being caught.

Owned.

He swallowed thickly. His hands clenched into fists against the desk.

And you—still gripping his wrist—lowered your mouth to his throat and let your teeth drag just beneath his jaw. Not biting. Not yet.

Just reminding.

Of what?

Of everything.

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

He jolted slightly under your touch. A sharp inhale. A curse under his breath. Then his voice—thin, almost petulant:

“You’re supposed to take orders.”

Your smirk was razor-edged.

“I do. Because I want to.”

Your grip dropped. But you didn’t move back.

Instead, you leaned in closer.

Jason didn’t flinch. He never did. But his breathing was heavier now, pulse hammering against his throat—visible. Vulnerable.

"You bark all day, but when I get too close," you whispered, dragging your hand down his thigh with deliberate slowness, "you start to sound like a mutt that wants to be bred, not obeyed."

Jason made a sound in his throat. Half-growl, half-gasp.

"Fuck you."

You grinned.

“You’d beg.”

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

He hated how much it was true.

He could sit on his throne all day—snapping orders, collecting blood money, running the city from his penthouse and dark alleys—but when you stepped into the room?

He was something smaller. Simmering. Waiting.

He wanted you to tear it out of him. To push him back onto the desk, force his legs open, make him say please.

You didn’t even need to touch him to get him there. He was already half hard just from your voice in his ear.

And you knew it.

You always fucking knew it.

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

“You don’t really want a guard dog,” you said, low against his throat. “You want a muzzle. You want a leash you can wrap around your own throat when no one’s looking.”

Jason’s fingers twitched again—this time reaching.

But not for a weapon.

For you.

And you let him. Just this once.

You let him grab your shirt, let him yank you in like he was desperate for something he couldn’t name. Your hand slid up the back of his neck, tangled in his hair, pulled his head back until he was looking up at you—eyes hooded, breathing uneven.

You watched his mouth part.

You watched the fight bleed out of his body.

And then, just loud enough to ruin him—

"Good boy."

　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

The leash comes first.

Black leather, clean and heavy, pulled from your coat pocket like you were always planning to use it.

Because you were.

You knew Jason would mouth off. You knew he’d call you his dog again.

So now you’re going to make sure he was your bitch instead.

You’re sitting on his desk, legs spread, Jason on his knees between them—cheeks flushed, eyes glassy. Still pretending to be angry. Still acting like he’s got pride left.

"Take your shirt off."

He hesitates. Barely. Then obeys. Peels it off like it’s armor, like maybe the fabric will hold him together.

It won’t.

You pull the collar tight around his throat and let the buckle snap into place. His breath catches.

"Doesn’t it suit you?" you murmur, thumb brushing the pulse at his neck. "No tie. No suit. Just a collar. That’s how I like you."

Jason mutters something low under his breath.

You grab his jaw. “What was that?”

His mouth twists, defiant. So pretty like this. “Fuck you.”

You smirk. “You’ll get there.”

You shove two fingers into his mouth before he can talk back. He chokes slightly, but glares up at you through his lashes. You drag them deeper, until his throat works around the intrusion and his spit starts to run down his chin.

"You wanted to talk back?" you murmur. "Then earn the right to use your mouth."

Jason moans around your fingers, eyes fluttering.

His knees shift. He’s already grinding down against the floor, trying to rub the ache building in his pants. You grab a fistful of his hair and yank—his eyes fly open.

"Are you hard just from choking on my fingers?" you whisper. "Are you going to cum from being used like a toy, Jay?"

He shakes his head. He wants to say no. But you curl your fingers around the collar, tug—not hard. Just enough.

He whimpers.

"That’s what I thought."

You unzip. Jason’s eyes drop, hungry. You slap your cock against his cheek, watching the weight of it sink in before gripping his hair again.

"Open."

He does. Mouth wide, eager.

You sink in slow—and he moans. Not a groan. Not a grunt. A real, ruined moan, like he’s been waiting for this all week.

"You love this, don’t you?" you growl, hips pushing forward until he gags. "Love being on your knees like some two dollar whore. Mouth wide open. Ready to be used."

Jason’s face is dripping. Spit down his chin, lips stretched wide, pupils blown. He nods. He nods.

You grab the leash.

Just the feel of it in your hand makes him shudder.

You wrap it around your fist and pull. Not hard. Just enough.

"Good boy," you murmur.

Then you start fucking his throat.

He chokes.

Of course he does.

You don’t stop.

You let him gag, let his shoulders shake, let his tears spill over—he loves it. He’s rutting against the floor now, desperate, whining around your dick like you’re the only thing he needs to breathe.

"You gonna cum just from getting facefcked like a bitch?" you hiss.

Jason nods—fast, frantic.

You laugh. Spit in his mouth. Slap his cheek. Pull the leash again and hold him there while your hips snap forward with brutal rhythm.

When you pull out, he’s wrecked. His jaw is hanging open, tongue out, spit dripping down his neck. And he looks gorgeous like this.

You grab his face. Make him look at you.

“Say it.”

He pants. "Wh-what?"

"Say who owns you."

Jason hesitates—just a second.

Then: "You."

"Say it louder."

"You fucking own me," he moans. "I’m yours. I’m your fucking dog."

You grin.

"Now beg to get fucked."

He doesn't even pause.

“Please,” he gasps. “Please use me. Please, I—I need it—I’ll be good, I swear, just—please.”

And just like that, Jason Todd—the Red Hood, the most feared boss in Gotham—is on all fours, begging for the dick you’re about to be giving him.

Face red. Lips swollen. Hair stuck to his forehead. He’s panting now, thighs trembling as he tries to hold himself together, cock hard and leaking with no relief. The collar glints under the light, tight around his throat, leash trailing from your fist like a reminder.

Jason Todd doesn’t look like a mafia boss anymore.

He looks like a dog.

And he’s about to get treated like one.

“Get up,” you say.

He moves. Clumsy. Obedient. You shove him over the desk, chest flat, ass up, back arching perfect for you. The position makes him groan.

His pants are already gone. You never gave them back.

His thighs part without being told.

Ready.

“You were begging so sweet a second ago,” you murmur, palming his ass. “What happened to all that pride, Boss?”

Jason bites his lip. Doesn’t answer.

So you slap his ass. Loud. Sharp.

He jolts. “F-fuck—!”

“You forget how to talk?” you growl, leaning in close, letting your weight press into him from behind. “You forget who owns this?”

Your fingers drag down to his entrance. Wet. Twitching.

Jason gasps. “N-No—no, I know—I know—”

“Then say it.”

You shove two fingers inside him without warning. He screams. His back arches off the desk, legs shaking instantly.

“Fucking say it.”

“You—y-you own me,” he moans. “Please, please—I'm your fucking toy—”

You laugh against his ear.

“Yeah, you are.”

You press your cock to his slicked-up hole, teasing, dragging the head against him until he’s shivering and whining, back arched beautifully. The moment you press in—

He sobs.

"F-fuck—you're big—slow, slow—"

You don't go slow.

You grip the leash and pull as you sink in, one sharp thrust that fills him to the hilt. Jason’s scream gets buried in the desk wood, his fists clutching the edges like he’s trying to ground himself.

"You’re taking it," you growl. "Every inch. Just like you begged for."

Jason moans—high, desperate.

You start fucking into him, pace unrelenting, cock pistoning in and out as his hole squeezes around you so tight it hurts. He’s already leaking onto the desk, leaving a wet spot beneath him.

“Gonna cum like this?” you hiss. “No hands, no touch—just getting bred like the good bitch you are?”

He nods frantically, words lost in sobs and moans.

You feel the tremble before you hear the whimper.

Jason’s voice cracks. His whole body shudders. And then—his cock twitches untouched, shooting over the desk as his body clamps down around you.

He’s crying now. Quiet, desperate.

“C-Came—fuck, I came—”

You don’t stop.

“You think we’re done?” you growl, voice filthy. “You begged for it. Now fucking take it.”

You grab the leash, twist it around your fist, and pull his head back as you thrust harder, pounding into his overstimulated, raw hole until he’s a sobbing wreck on the wood, dripping and broken. You feel it building. Heat low in your spine. Jason’s still twitching, every thrust making his legs shake, tongue hanging out as he begs for more, whimpers turning breathless.

“You want it?” you growl. “Want me to fill you up?”

Jason nods frantically, barely coherent.

“Fucking say it.”

“Please—please cum in me—want it—need your cum—breed me—!”

You snarl, bury yourself to the hilt, and let go.

Hot, thick, endless—you spill into him like you’re trying to mark him from the inside out. Jason gasps, back arching beautifully as he milks you, his hole clenching greedily with every spurt of release.

The air reeks of sweat, sex, and ownership.

And he loves it. 　　　　　　　　　　　　⋆ ✩₊˚ ʚ♡ɞ ˚₊✩⋆

He collapses the second you pull out, limp and twitching, cum leaking down his thighs in thick streaks. His face is flushed. His eyes are barely open.

You wipe him clean with your handkerchief. Gently.

You kiss his shoulder once. Then his temple.

He breathes slow. Even. Peaceful.

And the collar? You don’t take it off.

You brush your fingers over it softly, smirking.

“You looked better on your knees than you ever did behind a desk.”

Jason—wrecked, dazed, marked from the inside out—manages a breathy laugh.

“Then put my name on the fucking tag next time.”

Hi hi! I just read your works and saw your requests were open.

So sub muzan x dom male reader?

Maybe reader is a rich heir like muzan and his childhood friend, their relationship before and after the demon thing happens? And I loved the dark reader concept.

Thank you if you do write it <3

"EVEN KINGS KNEEL"

pairing. Sub!Muzan Kibutsuji x Top!male reader

synopsis. even as a demon, even with immortality at his fingertips, muzan is still beneath him. he always has been. — 2.7k

warnings. mdni, nsfw, amab reader, brat!muzan, power imbalance, degradation, forced submission (consensual but reluctant), edging, mild fear play, mutual obsession disguised as hate.

a/n: sorry I haven't posted in a hot minute. I was working on a jason todd fic, but had no idea how to continue it (I think I just wrote too much and got brunt out) anyways enjoy!

Muzan hated them.

The commoners. The peasants. The merchants who spent their days in the streets, moving freely beneath the golden sunlight. The men who trained as swordsmen, running drills until their bodies glistened with sweat. The children who sprinted through the fields, shouting with laughter, never once knowing the fear of collapsing in their own weakness.

It wasn’t fair.

He was the one born into nobility. He was the one who carried the bloodline of warriors and rulers. He was supposed to be above them all.

And yet, Muzan sat beneath the shade of the pavilion, his breathing uneven, his fingers gripping the armrest of his chair too tightly. Even now, beneath layers of silk and careful restraint, he felt the way his body ached from nothing. From existing.

It made his stomach churn with rage.

"How is it fair?" Muzan’s voice trembled with barely restrained fury, his dark eyes flashing as he stared at the courtyard. His fingers curled into his robes, nails digging into the delicate fabric. "I was born noble. I should be stronger than them. And yet—"

"—you can barely take five steps without needing to sit down?"

Muzan’s head snapped toward the voice, his scowl already in place.

Of course, it was him.

M/n stood nearby, watching him with that same infuriating smirk, the one that made Muzan’s teeth clench. He was dressed elegantly, his presence effortless, his posture relaxed yet undeniably dominant.

Muzan’s jaw tightened. "Don’t mock me."

M/n hummed in amusement, stepping forward, his movements slow, deliberate. He always walked like he owned the space he was in, and worse, like he owned Muzan, too.

"You do this every time," M/n said, voice rich with amusement. He came closer, standing over Muzan’s seated form, looking down at him like a misbehaving pet. "You act like the world has wronged you, like you deserve something greater. But all I see is a spoiled brat sulking because his body isn’t as strong as he wants it to be."

Muzan’s entire body tensed. His nails dug into his palms. "You—"

M/n didn’t give him the chance to finish.

A firm hand caught Muzan’s chin, fingers pressing against his jaw, forcing his gaze upward. Muzan sucked in a sharp breath, his body going rigid at the contact.

That damned smirk never wavered.

"Careful," M/n murmured, tilting Muzan’s head slightly, studying his expression. "If you sulk any harder, you might actually break something."

Muzan hated how easily M/n could do this. How easily he could touch him, tilt his chin, press his body into stillness with a single hand. And worse—how natural it felt. How Muzan’s body recognized the control, submitted to it even when his mind screamed at him to fight back.

His breath was uneven. His pride burned, sharp and humiliating.

"Shut up," he spat, jerking his head away from M/n’s grasp.

But M/n only laughed.

Low, knowing, completely unbothered.

Muzan could feel his pulse hammering at the sound.

"You always get like this," M/n said, stepping behind him, resting his hands over Muzan’s shoulders. The warmth of his palms seeped through the layers of expensive fabric, the weight of his touch steady, grounding. His fingers tightened, just enough for Muzan to feel the pressure. "You act like you hate your body, but you never actually do anything about it."

Muzan’s breath caught.

He bit his lip hard, his nails digging into his palms.

He hated how those words got to him. How they settled deep inside him, curling around the part of him that knew it was true.

But what infuriated him the most—what truly made him seethe—was the fact that despite everything, despite how much he hated himself, hated his fate, his weakness...

M/n never left.

Everyone else whispered behind his back, pitied him, spoke to him like he was fragile. The doctors prodded at him, his family tolerated him, the world resented him.

But M/n?

M/n never cared that he was sickly. Never allowed him to wallow in it. Never let him pretend that he was anything more than a furious, bitter, weak noble.

And yet, he was always there.

And Muzan hated how much he needed that.

　　　　　　　　˚₊‧꒰ა . ——— ˗ˏˋ ✮ ˎˊ˗ ——— ˖ ໒꒱ ‧₊˚

Muzan Kibutsuji had never been weak.

At least, that’s what he told himself.

He wasn’t weak when he gasped for air in the middle of the night, his body burning with fever. He wasn’t weak when the doctors murmured behind his back, whispering about how long he would last. He wasn’t weak when he sat under the pavilion, forced into the shade while the world beyond him ran wild under the sun.

And he definitely wasn’t weak when he was beneath him.

Muzan clenched his fists. His breath was uneven, his body betraying him even as he tried to fight it.

He was lying on his back, silken robes barely covering his skin, his throat still aching from the grip that had held him in place moments before.

Above him, Reader smirked. Always smirking.

"You're shaking," Reader murmured, voice rich with amusement as he traced his fingers over Muzan’s stomach, feeling the way his muscles tensed.

Muzan scowled, twisting in a pathetic attempt to escape the touch. "Fuck you."

Reader only laughed, pressing him down into the futon with a single hand against his chest. "What was that?"

Muzan hated this. Hated how easily M/n could do this to him—how he could pin him without effort, holding him still like some helpless thing.

But worst of all?

He hated how his dick twitched when M/n’s voice dropped into something dangerous.

"Say it again," M/n murmured, fingers sliding down Muzan’s stomach, moving toward the silk belt barely holding his robes together. "I dare you."

Muzan gritted his teeth, glaring up at him. He wanted to fight. He wanted to spit something cruel and furious, to claw at any remaining pride he had left—

But then—

"Oh?" M/n grinned, tilting his head. "You’re hard."

Muzan froze.

His stomach dropped. His entire body burned with humiliation as M/n’s fingers ghosted over the growing bulge beneath his robes.

A choked sound escaped Muzan’s throat. "I—!"

"You what?" M/n interrupted, his grip tightening over Muzan’s jaw, forcing him to look up. "You’re weak? You’re pathetic? Or—" he leaned in, his lips ghosting over Muzan’s ear, "are you just my little whore?"

Muzan trembled. His thighs clenched, his breath coming in sharp, uneven gasps.

He hated this. Hated how his body responded to those words. Hated how his cock pulsed at the sheer filth dripping from Reader’s tongue.

M/n hummed, taking his silence as an answer. "That’s what I thought."

With one sharp tug, Muzan’s robes came undone, the silk sliding from his body like water, leaving him bare beneath Reader’s gaze.

Muzan’s breath hitched. "Don’t—"

"Don’t what?" M/n’s voice was mocking. "Don’t look? Don’t touch?" His fingers curled around Muzan’s dick, stroking slowly, just enough to make him gasp. "But you’re already leaking, love. That’s disgusting."

Muzan let out a strangled whimper, his hips twitching despite himself.

M/n smirked. "You act like you hate this, but your body always tells the truth."

Muzan’s pride was in shambles, his mind spinning, but the worst part—the absolute worst—was that he knew M/n was right.

His body had always belonged to him.

"Turn over."

Muzan’s heart stopped.

He stared up at M/n, wide-eyed, his lips parted. "No."

"No?" M/n’s grip tightened over his thigh, his voice dropping into something dangerous. "Did I ask?"

Muzan shuddered. His throat bobbed as he swallowed hard.

He could fight. He could resist.

But they both knew what was going to happen.

Slowly, humiliated, aching, Muzan turned onto his stomach, pressing his heated face into the sheets.

M/n laughed, his hands sliding down Muzan’s back, pushing his thighs apart, exposing the tight little hole that clenched instinctively beneath his gaze.

"Good boy," M/n purred. "Now, let’s see how much you can take tonight."

Muzan gritted his teeth, his entire body tense, every instinct in him screaming at him to fight back.

But he didn’t.

Couldn’t.

Not with M/n’s hands gripping his thighs, spreading them apart, forcing him open as if he were nothing but a doll to be played with.

Not with his face buried in the sheets, his breath coming in sharp, humiliated little gasps as he felt everything—the weight pressing him down, the heat sinking into his skin, the ache between his legs that he could not ignore.

Not when M/n’s voice was sinking into his spine like liquid fire.

"Good boy."

Muzan whimpered. The sound slipped past his lips before he could stop it, weak and ruined, his whole body burning with shame.

"See? You pretend to fight me. But your body? Your body knows better."

Muzan bit his lip hard, but it did nothing to stop the way his ck twitched, aching and needy, pressed against the futon as M/n’s fingers skimmed over the soft skin of his inner thighs, teasing him.

"Say it."

Muzan froze. His stomach dropped.

He swallowed, voice raw, heart hammering too hard, too fast.

"Say what?"

M/n chuckled darkly, fingers digging in just hard enough to make Muzan twitch beneath him.

"Say what you are."

Muzan shook his head violently, face burning, breath uneven. "I—"

"Say it."

"Fuck you," Muzan snarled, his voice shaking, trying desperately to keep the last fragile pieces of his dignity intact.

He shouldn’t have said that.

Because the moment the words left his mouth, M/n’s fingers slammed down on his hips, gripping hard, dragging Muzan’s hips up, forcing him onto his hands and knees.

Muzan let out a sharp, choked sound, his body betraying him completely—thighs shaking, arms weak, his cock dripping against the sheets.

He was exposed.

Humiliated.

And the worst part?

He knew M/n was staring.

"Look at you," M/n murmured, dragging his fingers down the curve of Muzan’s ass, making him tense. "You say you hate this. But you’re so—"

A hand suddenly slid down, fingers brushing over Muzan’s twitching hole.

Muzan jerked violently, a strangled, desperate noise escaping his lips.

M/n grinned.

"So desperate. So needy. Like a filthy little slut."

Muzan whimpered, his hands clenching into the sheets, humiliation crashing down on him in thick, unbearable waves.

"Still think you have control, love?"

Muzan’s pride screamed at him to fight, to say something biting and cruel, to claw at whatever dignity he had left—

But then—

A single, slick finger pressed against his tight, twitching hole, circling, teasing—

And Muzan broke.

"P-Please—"

The second the word left his lips, M/n went still.

The room was silent, except for Muzan’s shaky, uneven breathing, his whole body trembling beneath him.

Then—

M/n laughed.

Deep, dark, merciless.

"You really are pathetic."

Muzan shuddered, tears burning at the edges of his eyes, a sharp, humiliating ache spreading through his body as M/n pulled back completely, leaving him empty and untouched.

Muzan’s breath hitched in disbelief. "W-What—"

"You don’t deserve it."

Muzan froze, his entire chest seizing up.

No.

Not this. Not now.

M/n leaned down, his breath hot against Muzan’s ear, his fingers digging into his hips, holding him still.

"You think you can fight me, and still get what you want?"

Muzan’s mind spun, his dick aching, his entire body burning with unsatisfied need. "P-Please—!"

M/n hummed. "Please, what?"

Muzan bit his lip hard, humiliated beyond belief, but his body was too far gone. His pride was shattered.

And so, he whispered—

"P-Please… fuck me…"

M/n grinned, dragging his fingers down Muzan’s spine slowly, making him shudder.

"Oh, sweetheart." M/n’s voice was mocking, but sweet, dripping with dark amusement. "That’s not how this works."

Muzan barely had time to process the words before Reader’s hand cracked across his ass, the sharp smack making him jerk violently, his cock twitching, a wrecked, gasping moan spilling from his lips.

M/n grabbed his neck, tilting his head back slightly.

"You don’t get to beg for my cock when you’ve been a brat all night."

Muzan’s breath shuddered, his eyes glassy, his entire body shaking.

"You’ll take what I give you. Nothing more."

Muzan felt his pride crumble, his whole body on fire, mind swimming in humiliation and unbearable need.

And when M/n’s fingers finally, finally pressed inside, filling him—

Muzan sobbed.

　　　　　　　　˚₊‧꒰ა . ——— ˗ˏˋ ✮ ˎˊ˗ ——— ˖ ໒꒱ ‧₊˚

The night Muzan turned him, he was certain he was making his greatest weapon.

M/n had always been the only one he could never shake, the only person who could make him feel weak, even as a human.

So he made him first.

Not a test subject. Not an experiment.

His first creation. The first demon.

A gift.

Or at least, that’s what he thought.

But something went terribly wrong.

M/n did not become like the others.

He was not weak to the sun. He did not obey orders. He was not bound to Muzan’s will like the others who came after him.

In fact, it was the opposite.

From the moment M/n opened his eyes as a demon, from the moment he stood before Muzan, something in his very presence made Muzan’s entire being lock up in terror.

The realization hit him like a blade to the throat—

M/n was not his servant.

He was his rival.

No—his captor.

His leash.

And there was nothing he could do about it.

　　　　　　　　˚₊‧꒰ა . ——— ˗ˏˋ ✮ ˎˊ˗ ——— ˖ ໒꒱ ‧₊˚

"You look nervous, love."

Muzan hated that voice.

The mocking amusement. The way it was never afraid, never shaken, never beneath him.

Even now, even after everything, as M/n leaned against the window, golden sunlight spilling over his shoulders, he looked untouched. Untouchable.

Muzan should be the one sitting there.

And yet, he was not.

Instead, he was kneeling.

His breath shaky, his muscles tense, his mind screaming at him to run.

But he wouldn’t.

He couldn’t.

M/n smirked, tilting his head slightly, watching Muzan with knowing amusement. "What’s wrong? You look like you’ve seen a ghost."

Muzan’s throat felt dry.

Because he knew.

He knew exactly what was wrong.

He had tried to chain M/n to him.

And instead, he had forged his own leash.

Muzan had spent centuries avoiding the sun.

But M/n?

M/n bathed in it.

　　　　　　　　˚₊‧꒰ა . ——— ˗ˏˋ ✮ ˎˊ˗ ——— ˖ ໒꒱ ‧₊˚

He sat in the daylight like it was his birthright, like it had never burned him, like it was mocking Muzan with every golden ray.

It made something inside Muzan curl in fury, in resentment, in humiliation.

But also—

In want.

Because no matter how much he hated it, no matter how much he despised his own weakness, it only made M/n’s power more intoxicating.

Muzan was supposed to be the strongest.

Yet here M/n was—untouchable, unbreakable, immune to the very thing that haunted Muzan’s every waking moment.

He had tried to turn M/n into his, and instead, M/n had become the one being in existence that could never be controlled.

And worst of all?

Muzan loved it.

　　　　　　　　˚₊‧꒰ა . ——— ˗ˏˋ ✮ ˎˊ˗ ——— ˖ ໒꒱ ‧₊˚

"You’re sulking again, love."

Muzan scowled, his fangs bared, but M/n only chuckled, stepping closer, letting his shadow loom over him.

There was affection in it, somewhere. Hidden beneath the cruelty. Beneath the taunts.

Because the truth was—

Muzan was a brat.

And M/n was the only one who knew how to handle him.

"You act like you hate me," M/n mused, leaning in, brushing his lips against Muzan’s ear, his fingers curling beneath his jaw. "And yet, you never run."

Muzan’s breath hitched.

Because he was right.

He never did.

M/n tilted Muzan’s head back, studying him—not with fear, not with submission, but with something that had never changed.

"Tell me, Muzan," he whispered, his voice silken and dark, curling around Muzan’s spine like a snake. "Are you mine?"

Muzan trembled.

His fingers curled into the fabric of M/n’s robes, his pride screaming at him to resist.

But M/n was patient.

He had always been patient.

And so, as M/n’s fingers tightened around his throat, as Muzan’s breath shuddered, as his body betrayed him once again, he finally—

Finally.

Let the words slip past his lips.

"Y-Yes."
