AN: I know it’s no longer Valentine’s Day but I hope this is to your liking! It was actually very interesting and enjoyable to write. I haven’t written smut like this before. That’s why I waited until last to post this one. @compersian happy belated Valentine’s Day.
A Valentine's Day like no other
The studio breathes with amber light, each candle flame a quiet pulse against the darkness. I've spent hours arranging them—along the windowsills, clustered on my workbench, scattered across the floor in deliberate chaos. The air is thick with melted wax and linseed oil, and underneath it all, her perfume when she arrives.
Y/n stands in the doorway, backlit and beautiful, her eyes adjusting to the dim warmth. "Hyunjin," she whispers, and my name on her lips always sounds like a prayer I don't deserve.
"Come here," I tell her, my voice lower than I intend. There's something coiled tight in my chest tonight, something I've been keeping locked away for months. Years, maybe. A hunger that has nothing to do with love and everything to do with possession.
She moves toward me, trusting, always trusting, and I wonder if she can see it in my eyes—the want that's darker than devotion.
"You're going to paint me?" she asks, a smile playing at her lips. She knows the drill. We've done this before, her body draped across my velvet chaise, my brush translating her curves into something eternal.
"Something like that," I murmur, reaching for the jars I've prepared. Not my usual oils. Something thicker. Tempera paint in shades of crimson so deep they're nearly black, pigments that cling like sin.
Her eyes follow my hands. "That's not your usual palette."
"No." I step closer, close enough that she has to tilt her head back to hold my gaze. "Tonight I want to paint on you. Not a portrait of you. You become the canvas."
Something flickers across her face—surprise, curiosity, a spark of something that might be arousal. "Okay," she says softly.
But I need more than okay. I need her to understand what she's agreeing to.
"I need you to trust me," I say, my fingers finding the curve of her jaw, tilting her face toward the candlelight. "What I want to do tonight... it's not gentle. It's not sweet. I want to mark you. Cover you. Make you mine in a way that has nothing to do with words."
Her breath catches. For a moment, silence stretches between us, taut and electric. Then she nods, and her voice comes out steady, certain. "Show me."
The word breaks something loose inside me.
I help her out of her clothes slowly, reverently, each piece of fabric falling away like a ritual. When she's bare before me, I guide her to the center of the room where I've laid down canvas drop cloths, protecting the floor but also creating our own isolated world.
"Close your eyes," I whisper.
I dip my fingers into the first jar—crimson like arterial blood, like crushed rose petals, like all the violent beautiful things I've ever wanted to say but couldn't. The paint is cold, and when I press my fingers to her collarbone, she gasps.
I drag my fingers down, slowly, watching the paint trail across her skin. Down the valley between her breasts, circling one, then the other, my touch deliberate and possessive. She trembles, and I'm not sure if it's from the cold or from something else entirely.
I paint her ribs like I'm counting them, committing each one to memory. My handprints bloom across her stomach, her hips, the soft skin of her inner thighs. Each touch is a claim, a brand, a way of saying mine in a language that transcends words.
"Hyunjin," she whispers, and there's a tremor in her voice now, something needy and raw.
"I know, jagiya. I know." But I'm not done. Not even close.
I move behind her, painting the curve of her spine, the small of her back, the swell of her hips. My hands are covered in crimson now, and when I press them to her shoulders, she arches into the touch.
"You're so beautiful like this," I murmur against her ear. "Covered in me. Wearing my obsession."
She turns her head, eyes finding mine over her shoulder. "I want more."
The words snap the last thread of my restraint.
I spin her around, and this time when I touch her, there's nothing gentle about it. My paint-slicked hands roam freely, urgently, leaving crimson streaks across every inch of her skin. I press her back against the wall, and the paint transfers there too, our combined heat creating abstract art on the white plaster.
Her hands find my shirt, pulling, and soon I'm just as covered as she is, our bodies sliding together in a mess of paint and want and something too intense to name. The candlelight flickers, casting our shadows huge and monstrous on the walls, and I think distantly that this is what I've always wanted—to consume and be consumed, to blur the lines until there's no separation between artist and muse, between love and possession, between creation and destruction.
"Look at us," I rasp, turning her so she can see our reflection in the darkened window. We're covered in crimson, inhuman, transformed into living art. "This is what you do to me. This is what I've been hiding."
She meets my eyes in the reflection, and her smile is feral, matching. "Don't hide anymore."
I bring our paint-slicked bodies to the chaise, the velvet already stained from months of our sessions together. The familiar piece of furniture looks different tonight—sacred, somehow. Sacrificial.
"Wait here," I tell her, my voice rougher than I intend. I run my paint-covered thumb over her bottom lip, leaving a small smudge of crimson there. She looks up at me with those eyes, pupils blown wide, and I have to look away before I lose my nerve entirely.
My heart is hammering so hard I can feel it in my throat. What I'm about to ask her—what I'm about to show her—this is the part of me I've kept locked away even from her. The desire that goes beyond possession, beyond marking. The hunger that has teeth.
My cock strains painfully against my black boxers as I cross to my drawing desk, each step deliberate. The box is exactly where I left it, slender and unassuming. Inside, six exacto knives, each one cleaned with surgical precision. I'd spent an hour sterilizing them, my hands steady despite the anticipation coiling in my gut. Planning this. Imagining this.
I select one, the blade catching candlelight as I turn back to her.
Y/n watches me with those big eyes—curious, lustful, trusting in a way that makes something in my chest ache even as darker urges pulse through me. I've been naked in front of her before, but tonight feels different. Revelatory. I hook my thumbs into my boxers and slide them down, my erection springing free, already leaking with want.
Her gaze drops, then drags slowly back up my body. I'm covered in deep red marks, handprints and streaks across my stomach, my chest, my thighs. My dark hair is a mess from her fingers. My lips are swollen from claiming hers again and again. And she looks at me like I'm a god and a monster all at once.
I watch her thighs press together, can see the slickness there even in the dim light. She wants this. Wants me, even the parts I haven't shown her yet.
"Sit down," I tell her, gesturing to the chaise. When I settle onto the velvet, I can feel the texture against my bare skin, paint transferring, our combined essence marking yet another surface. "Straddle me."
She obeys immediately, graceful even covered in crimson, and when she settles over my lap I can feel her heat, her wetness so close to where I'm aching for her. My free hand finds her hip, steadying her, my fingers pressing hard enough to leave new bruises beneath the paint.
"What's that for?" she asks, her voice soft, innocent, gesturing toward the exacto knife still clutched in my other hand.
I meet her eyes, and I don't hide what's in mine anymore. The hunger. The need for something more than just physical possession. I want to be inside her in ways that transcend flesh.
"For you," I say, my voice barely more than a rasp. The knife glints between us, beautiful and terrible. "I want you to mark me."
Her eyes widen, lips parting in surprise. I can feel her pulse quicken where our bodies press together, her breath coming faster.
"I want to give you control," I continue, my thumb tracing circles on her hip, feeling her tremble. "Just for this moment. I want to be inside you while you do it.”
I bring the blade up slowly, offering it to her handle-first. My cock throbs between us, so hard it's almost painful, and I can feel how wet she is, hovering just above me. The anticipation is exquisite torture.
"I want to watch you taste me," I breathe, my other hand sliding up her spine, pulling her closer. "Want to feel you ride my cock while you carve yourself into my skin. Want your tongue on the blood you draw from me. Want to know that I'm as much yours as you are mine."
Her fingers close around the handle, and the weight of the blade transfers from my hand to hers. The shift in power is immediate, electric. My breath catches.
"You understand what I'm asking?" I search her face, need and vulnerability warring in my chest. "I'm giving you permission to hurt me. To mark me. To take what you want from me while I'm buried inside you."
She tests the weight of the knife, and I watch her pupils dilate further, something dark and hungry blooming across her features that mirrors what I've been hiding.
"Where?" she asks, and her voice has changed—lower, rougher, matching the energy that's always lived in my shadows.
"Anywhere you want," I tell her, and I mean it. My chest, my shoulders, my arms—any canvas she chooses. "Just let me inside you first. I need to feel you around me when you do it."
I grip her hips with both hands now, lifting her slightly, positioning her over my aching cock. "Take me," I command, though I'm the one who's supposed to be relinquishing control. Old habits. "Sink down on me and then show me what you've been hiding too."
She lowers herself slowly, torturously, and when she takes me inside her—hot and tight and perfect—I nearly lose my mind. My head falls back against the chaise, a guttural sound ripping from my throat.
"Fuck," I breathe, my fingers digging into her hips hard enough to bruise. "You feel—"
But I don't finish the sentence because she's fully seated now, my cock buried to the hilt inside her, and she's bringing the blade to my chest. The metal is cold against my paint-slicked skin, and I can feel my heartbeat pounding against it.
"Tell me again," she demands, and hearing that authority in her voice while she's stretched around me does something primal to my brain. "Tell me what you want."
"I want you to cut me," I say, my voice shaking with need. "I want you to carve your name into my skin while you ride me. I want to bleed for you. I want you to lick it up, taste me, consume me the way I've been consuming you."
She starts to move, rolling her hips in a slow grind that has my vision blurring, and at the same time, I feel the first bite of the blade. Sharp, precise, deliberate. A line of fire across my collarbone that makes me gasp and buck up into her.
"Yes," I hiss through clenched teeth. The pain and pleasure tangle together, indistinguishable, perfect. "More. Don't stop."
She picks up her pace, riding me harder now, and with each thrust she adds another line, another curve, carving something into my skin that I can't see but can feel with every nerve ending. Blood wells up, mixing with the crimson paint, running in rivulets down my chest.
"Hyunjin..," she murmurs, and then she's leaning down, her tongue following the path of the blade, lapping at the blood she's drawn from me. The sensation is overwhelming—her mouth on my wounds, her pussy clenching around my cock, the knife still gripped in her hand promising more pain, more marks, more proof that I belong to her.
"Harder," I beg, and I'm not sure if I mean her movements or the blade. Maybe both. Probably both. "Take everything. I'm yours. Fucking ruin me."
She sits back up, and I can see my blood on her lips, smeared across her mouth like the world's most obscene lipstick. She looks feral. Divine. Terrifying. Mine.
The blade returns to my skin, this time across my shoulder, and she grinds down on me so hard I see stars. I'm drowning in sensation—the burn of the cuts, the slick heat of her around me, the way she's looking at me like I'm something to be devoured.
"Come for me," she commands, her voice rough with her own pleasure. "I want to feel you fall apart while I mark you."
And God help me, I'm so close. Every thrust, every cut, every drop of blood she licks from my skin pushes me closer to the edge. My hands slide from her hips to her ass, gripping, pulling her down onto me with bruising force.
"Not yet," I grit out, even though my body is screaming for release. "Not until you finish. Whatever you're carving into me—finish it first."
She makes three more cuts—quick, precise, intentional—and I feel each one like a brand. The pain is sharp and clarifying, grounding me even as pleasure threatens to tear me apart. When she finally sets the blade aside, her work complete, she leans down and traces the entire pattern with her tongue, mapping whatever she's carved into my flesh.
"Your turn," she whispers against my bloodied skin, and the words hit me like a physical blow.
I go completely still inside her, my cock twitching with the effort of staying motionless. My hands freeze on her hips, fingers pressing into yielded flesh.
"What?" The word comes out strangled.
She sits up, riding me in one slow, deliberate roll of her hips that nearly shatters my resolve. Her hand finds the exacto knife, and she offers it to me handle-first, the blade still wet with my blood.
"Mark me," she says, and there's challenge in her voice, desire, a darkness that mirrors my own. "The way I marked you. Make me yours."
"No." The word tears out of me, visceral and immediate, even as my cock throbs inside her with want. "I can't—I could never—"
But she's already kissing me, deep and slow and devastating, and I taste myself on her lips—copper and salt and something primal. My blood in her mouth. The intimacy of it, the absolute wrongness and rightness of it, sends lightning down my spine.
"Please," she breathes against my lips, grinding down on me until I'm seeing stars. "I want to wear your marks. I want to match you. I want—"
Her tongue slides against mine, and I taste more of my own blood, and something inside me breaks open. Snaps. Gives way.
"Fuck," I groan, taking the knife from her trembling fingers. "Okay. Okay, but—" My free hand cups her face, forcing her to meet my eyes. "Just one. Small. I can't—I won't hurt you more than that."
"Yes," she whispers, arching against me. "Anywhere. Please, Hyunjin."
I pull out of her slowly, both of us gasping at the loss, and I guide her down onto her back on the paint-stained chaise. She's so beautiful like this—covered in crimson, her lips swollen and stained with my blood, her chest heaving, her thighs still slick from where I've been inside her.
The knife feels heavier in my hand now, the weight of responsibility, of trust, of something sacred and profane. I position myself between her legs, the head of my cock nudging at her entrance but not entering, keeping us both on that knife's edge of anticipation.
"Where?" I ask, though I already know. My gaze has been drawn to her breasts since she laid back, to the soft swell of flesh just above her hardened nipple. Perfect canvas. Tender flesh.
"There," she confirms, following my stare, and she arches her back, offering herself up like a sacrifice.
I lean down and take her nipple into my mouth first, swirling my tongue around the peaked flesh, feeling her shudder beneath me. My hand steadies against her ribcage, feeling her heartbeat racing against my palm. Then I pull back, bringing the blade to her skin.
"Breathe," I tell her, and I press the knife to that tender flesh just above her nipple.
The cut is small—barely an inch—a simple heart shape, careful and precise despite the way my hands are shaking. As the blade presses into her tender flesh, I thrust deep inside her, burying myself to the hilt. She gasps, back bowing off the chaise, her body caught between the sharp bite of the knife and the fullness of me stretching her.
"Shh," I soothe, even as something dark and possessive roars through me at the sight of her blood welling up. Mine. My mark. My girl. I pull back slowly, then drive into her again—deep, powerful, claiming—while I complete the second curve of the heart. Each thrust is deliberate, hard enough to make her cry out, but never rushed. I set the knife aside carefully and lean down, dragging the tip of my tongue over the small bleeding heart I've carved into her.
She tastes like copper and skin and something indefinably her, and I'm lost. Completely, utterly lost.
I establish a rhythm now—deep, grinding thrusts that have her whimpering beneath me, each one powerful and controlled. My blood from the cuts on my chest drips down onto hers, crimson on crimson, our wounds mingling as our bodies do.
"Mine," I growl against her throat, my hips rolling forward in another slow, devastating thrust. "Every fucking inch of you. Every drop of blood. Every breath. Mine."
I can feel my blood sliding between our bodies, can feel her small wound pressed against my chest as I cover her completely. The pain and pleasure merge until I can't tell where one ends and the other begins. Each thrust is measured, intense, driving deep enough to make her see stars.
"Look at me," I command, one hand tangling in her hair, the other gripping her hip hard enough to leave new bruises. "I want you to watch me fuck you. Want you to see who you belong to."
Her eyes lock with mine—pupils blown so wide they're almost black, glazed with lust and something deeper, darker. I drive into her with another powerful stroke, the obscene sound of our coupling filling the studio along with our ragged breathing.
"Say my name," I demand, leaning down to capture her mouth in a brutal kiss. Our tongues tangle, and I can taste both of us now—my blood, her blood, our combined essence. "Tell me who's making you feel this good. Who owns this perfect cunt."
"Hyunjin," she gasps against my lips, and I swallow the sound like it's oxygen. "Hyunjin, please—"
"Please what?" I punctuate the question with a particularly deep, grinding thrust that has her crying out. "Use your words, baby. Tell me what you need."
"More," she begs, her nails raking down my back, adding new wounds to the collection. "Harder. I need—I'm so close—"
"You're going to come on my cock while I'm bleeding on you," I tell her, my voice rough and dark. I slam into her with more force now, each thrust deep and claiming but still controlled, never losing that deliberate intensity. "You're going to scream my name so loud the neighbors hear it. And you're going to remember this every time you see that mark on your skin. Remember who put it there. Who you belong to."
I can feel her tightening around me, her body coiling tighter and tighter, ready to snap. I shift the angle of my hips, hitting that spot inside her that makes her vision blur, driving deep with each powerful stroke. Relentless. Claiming.
"That's it," I encourage, my mouth finding her ear, my teeth grazing the sensitive skin there. "Come for me. Let me feel you fall apart. Show me I'm the only one who can make you feel like this."
My own orgasm is building at the base of my spine, white-hot and inevitable, but I hold it back through sheer force of will. She comes first. Always.
"Hyunjin!" Her back arches completely off the chaise, her pussy clamping down on me like a vice, and she's screaming my name exactly like I demanded, raw and desperate and perfect.
The feeling of her coming around me—the rhythmic clenching, the flood of wetness, the way she's shaking—destroys the last of my control. I bury my face in her neck and let go, my own release tearing through me with devastating force, my hips driving into her in deep, powerful strokes as I fall apart.
"Fuck, fuck, fuck," I groan against her skin, my hips still moving with that same intense, deliberate rhythm as I empty myself inside her.
We stay locked together as the aftershocks roll through us both, our blood and paint and sweat and cum all mixed together, impossible to separate. I can feel our hearts beating in sync where our chests press together, can feel her small wound still bleeding against my larger ones.
When I finally lift my head to look at her, she's smiling—sated and wild and beautiful. The small heart I carved into her breast has stopped bleeding, but it's there, permanent, a testament to this moment. To what we are to each other.
"Happy Valentine's Day," I murmur, kissing her softly this time, tender despite the carnage we've created.
She laughs, the sound breathless and perfect, like music echoing through the candlelit studio. "I love you," she whispers to me, her voice soft and tender as I begin to shift my weight, preparing to get up to retrieve something to clean her with, to care for the small wound I've carved into her skin.
I can't help but smile down at her, my heart swelling with an emotion so intense it nearly overwhelms me. My beautiful girl. My everything. "I love you, Jagiya," I murmur back to her, the words falling from my lips like a sacred vow. Pressing a chaste, gentle kiss to her temple—so different from the brutal claiming of moments before—I reluctantly move away from her warmth, making my way to the bathroom to gather the supplies needed to clean and care for her wound properly.
But as I pass by the large mirror hanging on the wall, I can't help but pause, unable to ignore the absolute mess she has made of me. My hair is wild and disheveled, standing up in every direction where her fingers have run through it desperately. My lips are swollen and bloodied, evidence of our violent kisses and the copper taste we've shared. My chest is a canvas of chaos—marked with streaks of crimson paint and darker red blood, the colors blending together in abstract patterns that tell the story of our passion. But there, just above my heart, carved with deliberate precision into my flesh, are her initials. They look like claw marks scored directly onto my soul, and I find myself hoping—praying, even—that they scar permanently. I never want these marks to fade, never want to lose this physical reminder of what we've shared tonight, of who I belong to just as much as she belongs to me.
