✩°˖🫐 ⋆。˚꩜ now playing ‘don’t smile’ - Sabrina Carpenter
synopsis: they broke up for a reason, but that never seems to matter when it comes to each other. Weeks of silence always end the same way—one late-night text, one more meeting, one more promise that it’s the last time. But every reunion feels too familiar, slipping back into something that never really left. The problem isn’t that they don’t care anymore—it’s that they care too much, just not in a way that works. And when he realises she might actually be okay without him, he can’t help but want one thing: for her to miss him the way he misses her.

The silence between them had lasted three weeks this time. Three weeks of Ni-ki staring at his phone, tracing the outline of your contact name, wondering if you had finally found someone who didn't make you cry, or if you were staring at her ceiling wondering the same thing about him.
Then came the text. “Are you awake?”
It was 2:14 AM. It was a lie—they were both wide awake, haunted by the ghost of a relationship that refused to stay dead.
When he arrived at your door, the tension was thick enough to choke on. The moment she opened it, the air shifted. They didn't speak; they didn't need to. The arguments that had torn them apart—the jealousy, the suffocating possessiveness, the screaming matches that ended in shattered glass—were pushed to the periphery. All that mattered was the magnetic pull that always dragged them back into the same destructive orbit.
Ni-ki didn't wait for an invitation. He stepped inside, slammed the door shut, and pinned her against the wall. His hands were rough, gripping her waist with a desperation that bordered on aggression.
The tension was thick enough to choke on. The moment she opened it, the air shifted. They didn't speak; they didn't need to. Ni-ki didn't wait for an invitation. He stepped inside, slammed the door shut, and pinned you against the wall, his hands gripping your waist with a desperation that bordered on aggression.
"I heard you were seeing someone," he hissed, his voice low and dangerous. "Tell me you're still mine. Tell me you haven't let anyone else touch you."
"We're broken up, Ni-ki," you breathed, though your hands were already sliding up his chest.
"You're never not mine," he growled, crashing his lips onto hers in a collision of teeth and tongue.
He pulled back just an inch, his breath hot. "You think you're okay without me? I can see it in your eyes. You're fucking starving for this."
The kiss was a war. It wasn't sweet or longing; it was a collision of teeth and tongue, a frantic attempt to reclaim territory. He tasted like mint and resentment. He pushed you further back, his knee forcing its way between your thighs, grinding against your center through your thin clothes.
"Look at you," he whispered, his voice dripping with a mix of degradation and desire. "So desperate for your ex. You're such a little slut for me, aren't you?"
He slid two fingers deep inside you without warning, a sharp gasp escaping your lips. He pumped them ruthlessly, his thumb circling your clit with a precision that knew exactly how to break you. He watched your face, savoring the way your eyes rolled back, the way you lost her grip on reality.
"That's it. Take it," he commanded, his voice shifting into that praise he knew you craved. "Good girl. Just take it for me."
Instead of rushing to the bedroom, Ni-ki decided to make her wait. He stepped back just enough to create a torturous gap between them, his eyes dark as he watched your chest heave. He slowly reached down, unbuckling his belt with a deliberate, clicking sound that echoed in the quiet hallway. He slid his trousers down, letting his hard, thick cock spring free.
"Get on your knees," he commanded.
You didn't hesitate. You sank to the floor, her eyes locked on him. Ni-ki didn't let you take him immediately. Every time you leaned in to lick the head of his cock, he gripped her hair and pulled your head back, forcing you to look up at him.
"Not yet," he teased, his voice a cruel purr. "I want you to beg for it. Tell me how much you missed this. Tell me how much you want to taste me."
"Please, Ni-ki... I want you. I missed you so much," you whimpered, her lips glistening.
"Good girl." He finally released his grip, pushing his cock deep into your throat. He groaned as your warm mouth clamped around him, the suction tight and desperate. He didn't let you set the pace; he gripped the back of your head, thrusting his hips forward, forcing you to take every inch of him. He loved the way you gagged slightly, the way your eyes watered, the sound of her struggling to breathe while you worked to please him. He fucked you mouth ruthlessly, his breath hitching as you used your tongue to swirl around the head, driving him toward a premature edge.
Just as he felt himself peaking, he pulled out with a wet pop.
"My turn," he whispered, a smirk playing on his lips.
He didn't give you time to recover. He grabbed you by the waist and hauled you up, spinning you around and shoving you face-down against the hallway table. He ripped your panties aside, exposing your soaking wet pussy to the air.
He didn't go inside you yet. Instead, he used his tongue to tease the outer lips, licking you slowly from bottom to top, making your hips twitch and her breath hitch. He flicked his tongue over your clit with agonizing precision, teasing the sensitive peak without fully committing to the pressure.
"You're so wet for me," he murmured against your skin, his voice vibrating through her. "Did you think about me while you were alone? Did you touch yourself and imagine it was my cock inside you?"
He suddenly dove in, his tongue swirling deep inside you, eating you out with a hunger that was almost violent. He sucked your clit into his mouth, pulling and swirling his tongue in a way that sent electric shocks through your entire body. You screamed, your fingers clawing at the edge of the table, your legs shaking. He knew exactly how to break you, alternating between soft, teasing licks and hard, demanding suction until you were sobbing, your body arching off the table in a desperate attempt to get closer to him.
He felt her muscles begin to spasm, the first wave of an orgasm hitting you, but he pulled away abruptly, leaving you shivering and overstimulated.
"Now," he growled, his voice thick with desire, "we go to the bed."
He dragged you towards the bedroom, the hunger between them now an uncontrollable fire. He stripped you bare in seconds, his eyes roaming over your body with a possessive hunger. He pushed you onto her stomach, flipping you over so your ass was hiked up.
The sound of his palm hitting your cheek echoed in the room.
You cried out, a mixture of shock and arousal.
"Who do you belong to?" he demanded, spanking you again, leaving a blooming red mark on you pale skin.
"You... I belong to you," you sobbed, your voice trembling.
Ni-ki groaned, the sound guttural. He didn't use a condom; he never did. The risk was part of the toxicity, the ultimate sign of a bond they couldn't sever. He entered you in one heavy, punishing thrust, filling you completely. He didn't start slow. He hammered into you, his hips slamming against yours with a rhythmic, violent intensity.
He reached around, grabbing your breasts and squeezing them hard, pulling you back against his chest as he fucked you. He whispered filth into your ear—how you were nothing without him, how no one else would ever handle you this way, how you were his favorite toy to break.
As the friction built, Ni-ki flipped you over, pinning your wrists above your head. He slowed down for a moment, staring deep into your eyes, wanting you to see the obsession there. He began to move again, shallower this time, hitting your G-spot with every thrust, driving you toward an edge you couldn't escape.
"Please," you whimpered, your body shaking. "Ni-ki, please..."
"Please what? Tell me what you want, you pathetic little thing," he teased, increasing the speed.
"I want to cum! Please let me cum!"
"Good girl," he whispered, his voice suddenly tender, though his movements remained rough. "Cum for me. Give it all to me."
You shattered, your internal muscles clamping tight around him as a violent orgasm ripped through her. Ni-ki didn't stop; he kept pushing, driving you into a second, then a third peak, overstimulating you until you were sobbing, your body twitching under his.
He finally let out a low roar, thrusting one last time as he came deep inside you, filling you with everything he had. He collapsed on top of you, their breathing synchronized, the silence returning to the room.
For a few minutes, they stayed like that—tangled, sweaty, and broken. The intimacy was a lie, a temporary bandage on a wound that wouldn't heal.
Ni-ki pulled away slowly, his expression hardening as the post-coital haze cleared. He looked at you, seeing the marks he'd left on your skin, and felt a surge of satisfaction. You wouldn't be thinking about anyone else for a long time.
"I'm leaving," he said coldly, already reaching for his clothes.
He stopped at the door, looking back over his shoulder with a smirk that didn't reach his eyes. "Don't worry. I'll text you in a few weeks."
What was once a blissful moment had turned sour far too quickly. You hadn’t seen Ni-ki in exactly a month, and yet your mind refused to let go of that night. It lingered in fragments—his voice, the way he looked at you, the feeling he left behind like something you couldn’t quite wash off.
He had made you feel something no one else ever had, and maybe that was the problem.
Because now everything felt… muted in comparison.
It wasn’t that you didn’t know who you were without him—you did. You just didn’t like how it felt. Quieter. Emptier. Like something was missing that only he had ever managed to fill.
And no matter how much you tried to move on, your mind kept circling back to him, to the point where even the thought of someone else felt wrong—like you were comparing without meaning to.
You had tried reaching out at first. You told yourself it was only because you wanted to talk, because a month of silence felt ridiculous after everything the two of you had been through. Your first message had been simple, almost casual, but when hours passed without a response, you found yourself staring at your phone more often than you cared to admit. Eventually, you tried again.
So you had resorted to asking his friends, pretending it was nothing more than a passing question whenever his name slipped into conversation. Every single time, you received the same answer.
It had become almost laughable how often you heard it. Busy when you asked if he was around. Busy when you wondered if he was free to talk. Busy whenever you worked up enough courage to ask whether he had mentioned you at all.
And eventually, you stopped asking.
Not because you had stopped caring, but because you were beginning to hate the feeling of being the only one reaching for something that had already slipped through your fingers.
Still, a month later, you found yourself thinking about him as though no time had passed at all.
You hated how easily he could disappear from your life and somehow remain everywhere else—in your thoughts, in familiar places, in songs you couldn’t listen to anymore without remembering him. You hated that you could spend an entire day convincing yourself that you were finally moving on, only for one stupid memory to drag you straight back to the beginning.
Because after exactly one month of silence, your phone finally lit up.
His name appeared across your screen.
And just like that, every promise you’d made to yourself about staying away from him suddenly felt impossible to keep.
The thought had followed you the entire way, lingering at the back of your mind no matter how many times you tried to ignore it. It had been there when you picked out your outfit, when you stared at your reflection just a little too long, and even now, as you stood outside your friend’s place with music spilling faintly through the walls.
You almost turned around twice.
You told yourself you didn’t owe him anything. That you didn’t have to show up just because he texted. That one message—you coming?—shouldn’t have been enough to undo a month of distance.
It’s just a party, you tried to reason with yourself. He probably invited half the people he knows. This doesn’t mean anything.
But even as you thought it, you knew it wasn’t true.
Nothing with Ni-ki had ever been just anything.
The moment you stepped inside, the noise hit you first—laughter, music, voices overlapping—but none of it settled. It all felt distant, like background noise to something else, something heavier sitting in your chest.
You hated how quickly your eyes started searching.
Stop it, you told yourself immediately. You’re not here for him.
You tried to focus on anything else—faces you recognised, conversations you could join—but your attention kept slipping, drifting back to the same thought.
This is stupid. You shouldn’t care.
But before you could convince yourself to leave, your gaze caught on something—someone—and just like that, everything else faded.
He was standing across the room, half-turned, like he hadn’t noticed you yet. Or maybe he had, and he just hadn’t made it obvious. With him, it was hard to tell. It always had been.
You shouldn’t go over there.
You shouldn’t even look at him.
You know exactly how this ends.
But your feet didn’t listen.
They never did when it came to him.
Each step felt slower than it should have, like your body was hesitating even as it moved forward. Part of you wanted to stop, to turn around, to pretend you hadn’t seen him at all.
Because you knew what this was.
Not closure. Not a fresh start.
Just another mistake waiting to happen.
He noticed you when you were close enough that turning back would’ve been obvious. His eyes flicked up, landing on yours, and for a second—just a second—everything stilled.
That same pull you’d been trying to ignore for weeks.
You hated how nothing had changed.
“You came,” he said, like he hadn’t expected it, even though you both knew he had.
You forced a small shrug, crossing your arms like it might somehow steady you. “It’s a party,” you replied lightly. “Didn’t want to miss out on whatever mystery location you refused to explain.”
A hint of a smile tugged at his lips, familiar and frustrating all at once. “Did it matter?”
You let out a quiet breath, shaking your head. “It did to me.”
There was a pause, not awkward, but charged—like both of you were aware of everything sitting unspoken between you.
You shouldn’t be standing this close.
You shouldn’t be talking like this.
You shouldn’t feel this comfortable.
That was always the problem.
“I didn’t think you’d actually come,” he admitted, softer this time.
You frowned slightly, glancing away for a moment before looking back at him. “Yeah, well… I almost didn’t.”
That should’ve been enough. It should’ve been the moment you stepped back, created distance, reminded yourself why this was a bad idea.
Because despite everything—the silence, the hurt, the way he had disappeared without explanation—standing here with him still felt… right.
And that was exactly why it scared you.
“You look good, though,” Ni-ki smirked, like he knew exactly what he was doing. Like he was enjoying this far more than he should’ve been.
A part of him hoped you had dressed up for him.
Another part of him wondered if you hadn’t.
“Hm,” you hummed lightly, tilting your head just enough to meet his gaze. “You noticed?”
“I always notice when it comes to you, pretty.”
That shouldn’t have had the effect it did.
You knew him. You knew the way he spoke, the way he threw words around so easily, like they didn’t carry any weight. You knew he was probably just messing with you, slipping back into something familiar without thinking twice about it.
So why did it still feel like this?
Why did your heart stutter so suddenly, like it had forgotten how to act around him? Why did warmth creep up your neck, settling into your cheeks before you could stop it?
You shouldn’t react like this.
Not after a month of silence that you’d spent trying to convince yourself you didn’t need him.
“You’re unbelievable,” you muttered, looking away for a second as if that might help you regain some composure.
“I’m just telling the truth,” he replied easily. “Believe it or not.”
That was always the problem.
For a second, neither of you said anything. The music thumped somewhere behind you, people brushed past, laughter spilling into the space around you—but it all felt distant. Like it had nothing to do with the two of you standing just a little too close in the middle of it all.
You became suddenly, painfully aware of it.
You could feel the warmth radiating off him, close enough that it made your thoughts blur at the edges. Close enough that it would only take the smallest movement—
Your fingers twitched at your side before you quickly stilled them, pressing your nails into your palm as if that would ground you.
You know exactly what happens when you let him get this close.
“So,” you said, forcing your voice to stay steady, even as your chest tightened. “Is this what you do now? Text people out of nowhere and act like nothing happened?”
His expression shifted, just slightly. Not enough for anyone else to notice—but you did.
“Not people,” he said quietly.
Your breath caught before you could stop it, and you hated how quickly he noticed. His eyes flicked over your face, like he was searching for something—some kind of reaction, some kind of proof.
Just a small step. Nothing obvious. Just enough to put space between you, enough to remind yourself that you weren’t that person anymore—the one who folded every time he looked at you like this.
But his hand caught your wrist before you could.
Your entire body went still.
You shouldn’t let him do this.
You shouldn’t let him touch you.
But you didn’t pull away.
His thumb brushed lightly against your skin, absentminded, like it was the most natural thing in the world. Like he hadn’t disappeared on you for a month. Like you hadn’t spent weeks trying to forget what it felt like to be this close to him.
“Why are you acting like that?” he murmured.
Your heart was pounding now, loud enough that you were sure he could hear it.
“Like what?” you asked, even though you knew exactly what he meant.
“Like you don’t—” he paused, jaw tightening slightly, “—feel this.”
Your gaze dropped to where his hand still rested against your wrist.
“You don’t get to ask me that,” you said, quieter now, your voice slipping despite your effort to keep it steady. “Not after just… disappearing.”
Something flickered across his face again—guilt, maybe, or something close to it—but it didn’t last long.
“You came tonight,” he said instead.
“That doesn’t mean anything.”
If that was even possible.
The space between you disappeared completely now, leaving no room for excuses, no room to pretend this was casual or meaningless or anything other than what it was.
Impossible to walk away from.
You should pull your hand back, take a step away, say something that would put distance between you again.
But instead, you stayed exactly where you were.
Because no matter how many times you told yourself this would only end in hurt…
You were already too far gone to stop it.
He said things like they meant nothing, while you felt everything.
And standing here now, with him looking at you like that—as if no time had passed, as if nothing had changed—you could already feel yourself slipping back into it.
This is exactly why you shouldn’t have come.
You knew how it would end.
And yet, you hadn’t walked away.
And maybe… that said more than you wanted it to.
“Ni-ki”, you whispered softly.
Ni-ki didn’t say anything, he just took one step closer to you, the faint scent of his minty breath brushed over you. His eyes slowly made their way to your glossy lips and then back to your eyes until he said the unexpected.
“God you’re perfect”. He said that as if it was a fact, a statement even that no one could argue with. He slowly brought his hand up to your check and gently brushed away a few stray hairs.
You slightly leaned into his touch and sighed. “What are you doing to me Ni-ki.”
Ni-ki didn’t stop. For once he let his heart take control instead of his mind.
“Let’s ditch this party”, he suggested, “come back to my place?”
“Please baby…let me make it up to you, let me show you how much I missed you”
The air between them was electric, a volatile mix of longing and desperation that had been simmering for weeks. The moment they stumbled through the door of Ni-ki’s apartment, the door hadn't even clicked shut before he had you pinned against it. But this time, the aggression was tempered with a starving kind of tenderness.
Ni-ki didn't rip your clothes; he devoured you. His mouth crashed onto yours, tasting of mint and hunger, his hands framing your face with a possessive grip. He pulled back just an inch, his forehead resting against yours, his breathing heavy.
"I fucking missed you," he whispered, his voice raw and trembling. "God, I missed you so much, baby. Tell me you missed me too."
"I did," you whimpered, your hands clutching the fabric of his shirt. "I missed you every second."
A small, satisfied smile touched his lips. "Good girl."
He swept you up into his arms, carrying you toward the bedroom. He laid you down on the sheets with a gentleness that felt foreign yet intoxicating. He stripped you slowly, his eyes roaming over every inch of your skin as if he were memorizing you all over again. When you were bare beneath him, he didn't rush. He started with your breasts, his thumbs circling your nipples, teasing them into hard peaks. He leaned down, taking one nipple into his mouth and sucking firmly, his tongue swirling around the sensitive tip.
"You're so beautiful," he murmured against her skin, his voice a low vibration. "My beautiful girl. You feel so good, baby. You okay? You like that?"
"Yes... please, Ni-ki," you gasped, arching your back.
"I've got you," he whispered, kissing the valley between your breasts. "Just relax for me. I'm going to take such good care of you."
He slid down your body, his kisses trailing over your stomach until he reached the junction of your thighs. He parted your legs wide, his eyes darkening at the sight of her already glistening. He didn't dive in immediately; he teased you first, his fingertips grazing your inner thighs, circling closer and closer to your clit without touching it. You whimpered, your hips twitching in search of friction.
"Patience, sweetheart," he teased, his voice a soft command.
Then, he dove in. His tongue was a weapon of precision, licking you from the bottom up in one long, slow stroke that made your toes curl. He focused on your clit, sucking it into his mouth and swirling his tongue with a rhythmic intensity. He could hear your breath hitching, your fingers tangling in his hair.
"You taste like heaven," he mumbled against your wetness. He looked up at you, his eyes searching yours. "You doing okay? Too much, or just right?"
"Right... oh god, Ni-ki, right there!"
He didn't stop until you were sobbing, your body shaking as the first orgasm ripped through you. He held you thighs steady, eating you out through the peak of your climax, ensuring you felt every single vibration of your own release.
As she came down from the high, Ni-ki crawled back up your body, his eyes soft. He kissed you deeply, tasting yourself on his lips. He guided your hand down to his cock, which was throbbing and hard.
"I want to feel you," he whispered. "Can you do that for me, baby? Use that pretty mouth."
You slid off the bed, kneeling between his legs. You looked up at him, and the look of pure adoration in his eyes made your heart ache. You took him in slowly, your lips sliding over the head of his cock, swirling your tongue around the rim before sliding him deep into your throat.
Ni-ki let out a choked groan, his hands finding your hair, not to force you, but to guide you. "Fuck, you're so good at this. Such a good girl for me." He watched you work, the sight of youf devotion driving him wild. "You're taking it so well, baby. You okay? Not too deep?"
You looked up at him, humming a confirmation, your eyes hooded. He let you set the pace for a few minutes, the suction tight and wet, before he gently pulled you up for a kiss.
"I can't wait any longer," he breathed.
He positioned himself at your entrance, pausing for a second to look you in the eyes. "I'm coming inside you, baby. I want to feel everything. You ready for me?"
"Yes, please, Ni-ki. Now."
He slid into you in one smooth, deep thrust, filling you completely. They both gasped, the sheer intensity of the connection making them shudder. He began to move, his pace steady and rhythmic, his movements focused on your pleasure. He leaned down, whispering praise into your ear with every thrust.
"You feel so tight... so perfect. My girl. My perfect, beautiful girl."
He shifted his angle, hitting your G-spot with a precision that had you screaming his name. He slowed down, checking in again, his voice thick with lust. "You still with me? You feeling this? I want you to feel every inch of me."
"I feel you... oh god, don't stop!"
He picked up the pace, his thrusts becoming harder, more urgent. He reached down, his thumb finding your clit and rubbing it in sync with his hips. The double stimulation was too much; you felt another orgasm building, a tidal wave of pleasure.
"That's it, baby. Give it to me. Come for me," he urged, his voice a commanding yet loving purr.
You shattered, your internal muscles clamping tight around him as you screamed into his shoulder. The feeling of your climaxing triggered his own; he let out a guttural roar, thrusting deep one last time as he filled you with hot, thick cum.
They collapsed together, skin slick with sweat and fluids. Ni-ki didn't pull away immediately; he stayed inside you, holding you close, his heart hammering against your chest. He kissed your temple, his voice a soft, exhausted whisper.
"I'm not letting you go this time, baby. I've got you."
And when the sun came up.
