"Baby, you look fuckin' fantastic in a suit."
Kiyoomi chuckles as he gently places his cufflinks in their velvet-lined box and starts to undo his tie. "Oh, really?"
There's no actual doubt behind the words - Kiyoomi just wants him to keep talking which Atsumu'll gladly do.
"Fuck yeah, Omi. God as my witness, the only time yer hotter than when in a suit is when yer takin' it off for me."
"Looks like it's your lucky night," Kiyoomi muses, shrugging off his jacket and hanging it neatly over the back of a chair. His long fingers move to the buttons at his neck, and Atsumu's gaze is fixed on them.
"Darlin', I've been lucky every day and night since y'agreed to be mine."
Kiyoomi huffs out a breath of air that ruffles the slightly messy curls hanging in his face, but his smile is genuine and blinding. The light flush on his cheeks makes him look ethereal, otherworldly, and Atsumu tells him as much.
"You're just full of big words tonight," Kiyoomi says with an amused glint in his dark eyes, crisp white shirt falling open to reveal the physique of a professional athlete. Atsumu's mouth goes a little dry and his hand twitches, itching to touch. "Are you trying to seduce me, Miya Atsumu?"
"Sure am, Miya Kiyoomi," Atsumu says, a little breathless as he speaks the name that makes him grin from ear to ear. "Been thinkin' 'bout yer cunt all damn day."
"Oh, I know," Kiyoomi says, a dangerous glint in his eye as he walks around the huge honeymoon suite bed to stand by Atsumu's side, looking down at him with a smouldering gaze. "You've been unashamedly groping me all night, even in front of my own parents."
"What can I say, baby," Atsumu grins, trying to shrug but the position of his arms makes the movement awkward. "I'm always one to appreciate beauty."
"Such a romantic," Kiyoomi says, and Atsumu's gaze drops lower when those gorgeous fingers, one of them now wearing his ring forever, start undoing Kiyoomi's belt. "With such a silver tongue you might even talk me into marrying you if I don't shut you up."
Atsumu's chest aches with how much he loves this man. "And how are ya plannin' on doin' that, sweetheart?"
"Oh, I can think of a few ways," Kiyoomi says softly, almost a whisper, and Atsumu shivers as he steps even closer. "Open up."
Maybe Atsumu should be embarrassed about how easy he is for Kiyoomi but today, tonight, he's so far past that concept. He willingly parts his lips around Kiyoomi's fingers, keeping their gazes locked as they sink deeper into his mouth. Atsumu swirls his tongue around the digits, sucking gently and delighting in Kiyoomi's soft gasp that goes straight to his core.
"Good," Kiyoomi purrs, and Atsumu's eyes roll back a little in his head. "Now, hold onto this for me."
Suddenly the warm fingers in his mouth are replaced by cold metal, and Atsumu's momentarily confused before he realises it's Kiyoomi's belt buckle. He carefully bites down, just tight enough to hold it in place as Kiyoomi uses the leverage of his teeth to slowly spin on the spot until the end of the belt falls out of the final loop of his immaculately pressed slacks.
"Who knew that loud mouth had so many uses," Kiyoomi says, voice a little husky as he plucks the buckle from Atsumu's teeth and discards the belt somewhere Atsumu doesn't care about. "I wonder what else I can make it do for me before sunrise."
"I could do a lot more for ya if I had the use of my hands, baby," Atsumu says, gently tugging at the cuffs anchoring him to the headboard to illustrate his point. "Could make ya gush across the entire room."
"Tempting, but maybe later," Kiyoomi says absent-mindedly, his featherlight touch trailing down Atsumu's bare torso and making his abs twitch. "I like you like this."
'Like this' is spread out on his back, naked save for his own white shirt sitting halfway down his biceps, and hands securely anchored to either side of the headboard. The bed in their suite has perfect holes and notches for these kinds of things - the people running this place must know people get kinky on their wedding nights.
Last night, while packing for their honeymoon, Kiyoomi had snuck the handcuffs into one of the suitcases and Atsumu had pretended not to notice. He's been thinking about them all day, a fire low in his gut, and despite his words there's nowhere else he'd rather be than right here, at Kiyoomi's mercy.
At his husband's mercy.
"Well, who am I to argue with the newest Miya," Atsumu grins and Kiyoomi rolls his eyes, fondly. "I'm all yers, gorgeous."
Something soft shifts across Kiyoomi's face and he pauses with a hand on his waistband, bending down to capture Atsumu's mouth in a sudden, searing kiss. Their tongues meet and Atsumu gasps, suddenly very aware of his half-chub that's rapidly hardening as Kiyoomi licks into his mouth.
"And I'm all yours, Atsu," Kiyoomi says, softly and with such raw emotion in his voice that Atsumu has to really rein himself in so he doesn't start crying and ruin the moment. "Always and forever."
"Omi," Atsumu whispers, nuzzling into the warm hand on his cheek and panting, just a little. "Please."
"You really think you're the only one who's been waiting for this all day?" Kiyoomi says with a soft yet teasing smile as he undoes his slacks and pulls them off those ridiculously long legs.
Atsumu catches a glint of gold on his underwear, and when Kiyoomi finally stands up straight to let him see he can't bite back a groan. On the soft black fabric of the boxers is the number 13, immaculately embroidered in silky gold thread. It sits right above the swell of Kiyoomi's cunt, glittering softly in the room's mood lighting like the bow on top of an exquisite gift. Atsumu stares at it, mouth going dry and dick growing harder.
"It belongs to you. I belong to you," Kiyoomi whispers almost reverently, hooking a thumb under the waistband and just holding, waiting. "I love you, Miya Atsumu."
Atsumu tries to rise onto his elbows and fails, helplessly tugging at his restraints. "Omi, fuck, ya gotta let me put my mouth on ya or I might go crazy."
The fingers on Kiyoomi's free hand touch his lips and Atsumu kisses them automatically, soft and reverent, staring up at the love of his life.
"Say it." Kiyoomi's voice is a little shaky and some might mistake it for nerves, but Atsumu knows it's all raw emotion. He knows it, because it matches his own.
"I love ya, Miya Kiyoomi."
The boxers fall to the floor and then Kiyoomi's straddling his face, gripping his hair and the headboard for leverage as he gets settled. Atsumu groans when his husband's pussy is finally in full view above him, neatly trimmed pubes already glistening with his arousal.
"Ya really weren't lyin' about waitin' for this, baby," Atsumu says breathlessly, tugging in vain on the cuffs as he tries to lift himself higher, get closer. "Fuck, yer nearly drippin' on me."
"Then make sure you don't waste a single drop," Kiyoomi purrs as he anchors his hand tighter in Atsumu's hair and finally, finally lowers himself down.
When the slick heats hits Atsumu's tongue, familiar and intoxicating in equal measure, he groans straight into Kiyoomi's core. He starts slow, drinking Kiyoomi's arousal straight from the source with careful, almost teasing rolls of his tongue. Kiyoomi lets out a pleased sigh that sounds like it's coming all the way from his toes, like all the tension in his body just evaporated, and gets a little heavier in his seat.
Atsumu doesn't mind. As he's told his husband many times before - if this is how he goes, he'll die a happy man.
Adjusting the position of his neck, Atsumu redirects his efforts towards Kiyoomi's clit. It's hard and pulsing as he traces lazy patterns around it, relishing in Kiyoomi's shuddering sighs. When Atsumu takes it into his mouth and sucks, Kiyoomi curses out loud.
"This is why I married you, you know," Kiyoomi says, a little out of breath as he slowly grinds on Atsumu's face. "Fuck, who knew such an infuriating mouth could also be so talented?"
Atsumu grins into his husband's cunt and starts getting to work in earnest. He dips his tongue into Kiyoomi's entrance, teases his soaked folds, and licks tight circles around his clit. He eats like it's his last meal on earth and he's determined to make it the best he's ever had. Above him Kiyoomi moans softly, sliding his other hand into Atsumu's hair for better leverage as he steadily rides his tongue.
"So good for me," Kiyoomi murmurs, and the praise zips through Atsumu's body like liquid fire. "Keep going, don't stop, that feels amazing."
Atsumu doesn't ever want to stop. He groans into Kiyoomi's heat and cranes his neck harder, loving the eager cunt above him with everything he has. He feasts with sloppy, open-mouthed kisses, with precision strikes right on every single one of Kiyoomi's weak spots, with hollowed-out cheeks as he sucks his husband's clit until fingernails dig into his scalp. He wishes so fervently he could grab Kiyoomi's hips and pull him down harder, fuck him on his tongue until both of them are covered in slick, but all he can do is tug at the cuffs keeping him bound.
"Fucking love your tongue," Kiyoomi pants, snapping his hips forward until his clit bumps Atsumu's nose. "Drives me fucking crazy, oh god, right there-"
Atsumu knows they're nearing the end, so as he's learned he flattens his tongue and lets himself be used. Kiyoomi always comes the hardest, screams the loudest, when he lets himself ride Atsumu's face without abandon. His pussy pulses against Atsumu's mouth, dragging back and forth in scorching strokes, clit grinding against his nose with increasing urgency.
"Getting close, baby," Kiyoomi moans, hips speeding up even more. "Make me come nice and hard and I'll undo the cuffs, let you fuck me however you want."
Atsumu almost growls, biceps bulging against his shirt as he pulls on the restraints, the muscles in his neck screaming as he pushes his face further into Kiyoomi's cunt. He feels Kiyoomi's muscles tighten, hears the hitching of his breath, and his cock kicks in anticipation. Kiyoomi's hips are frantic above him, babbling breathless words as he chases his bliss on Atsumu's tongue.
"Yes, oh fuck yes, coming, I'm coming!"
Kiyoomi's scream of pleasure pierces the air and Atsumu drinks it greedily, along with the slick gushing from his convulsing pussy. Kiyoomi's fingers are so tight in his hair that Atsumu swears he's losing a few strands, but what does that matter when his husband is shaking apart in ecstasy on top of him? His cock kicks again, leaking onto his stomach, as Kiyoomi moans and rides out his climax with erratic rolls of his hips.
Atsumu gasps when his mouth is freed, panting alongside Kiyoomi as the latter rides out the aftershocks. Atsumu's grin is wide and Kiyoomi's smile is soft, but by the glint in his eye Atsumu knows he's not going to go back on his word and their wedding night is far from over.
"You did so well, baby," Kiyoomi sighs happily, bending down to kiss him deeply as he starts undoing the right handcuff. "You deserve whatever reward your heart desires."
"Wanna marry ya," Atsumu says with a smirk, knowing Kiyoomi is a sucker for mushy affection right after an orgasm. "Wanna be with'cha forever, Omi."
"Granted," Kiyoomi chuckles, straightening up and reaching for Atsumu's other hand. "Anything else?"
"Wanna fuck ya till ya can't walk."
Kiyoomi's gaze is dark, his cheeks flushed and his chest heaving. It's the most beautiful Atsumu's ever seen him. The click of the second cuff being unlocked echoes in the room, and for a moment they just breathe together in silence while gazing at each other.
Then, Kiyoomi, breathless;
"Granted."
Atsumu moves like lightning.
His hands find Kiyoomi's waist and lifts him as best he can, getting out from under him. He flips him over onto all fours, pushes his chest down into the mattress, and plunges two fingers straight into that slick heat. Kiyoomi shouts, gripping the sheets as Atsumu drives in and out of him, teeth sinking into his bottom lip.
"Yer never gonna take another cock besides mine, ever again," Atsumu growls, pressing down on Kiyoomi's sweet spot and feeling him shudder. "Yer all mine, aint'cha, baby?"
"Yours," Kiyoomi pants, glancing up at Atsumu as best he can from where his cheek is pressed to the bed. "Fuck me, Atsu, please."
Atsumu decides he's been patient enough, and his cock is aching, so he pulls his fingers out and grips his shaft. His hands are trembling a little when he lines himself up, one hand on Kiyoomi's hip and the other guiding his cock in a few teasing strokes against soaked folds. Kiyoomi curses and arches his back deeper, presenting his cunt for the taking.
And Atsumu is only a man.
Pushing into Kiyoomi feels like coming home, it always has, and they both let out shuddering groans when Atsumu bottoms out. He only stays still for a moment, pressing soft kisses to Kiyoomi's back, before he straightens up. Kiyoomi licks his lips, breathing heavily as he gazes up at him in anticipation.
Atsumu's going to give him everything.
There's no going slow at this point, not when he knows Kiyoomi's wet and ready and he himself is beyond desperate. He fucks him hard, a vice grip on his hips and hard snaps of his hips. Kiyoomi moans like he's being paid for it but Atsumu knows it's all real, feels it in the clenching around his cock, sees it in how his husband's eyes roll back in his head.
"So perfect for me, so tight and wet," he groans, his thrusts almost manic as he watches the pleasure on Kiyoomi's face. "Fuck, ya were made for this, made for me, Miya Kiyoomi."
"I love your cock," Kiyoomi almost whimpers and fuck, Atsumu's not going to last long at this rate. "Harder, don't stop, I'll c-come again…"
"Anythin' for ya, baby," Atsumu pants, holding on tighter and driving his hips harder. His thighs burn and his own orgasm is not far off, but he'll be damned if he's going to miss out on Kiyoomi coming on his cock. "Go on, come for me, milk my cock with yer perfect pussy."
"A-almost, I'm… ah!"
Kiyoomi's entire body goes taut and then he clenches hard, moaning loud and raw as the orgasm ravishes his body. Atsumu's right on the edge, driven wild from the teasing and so stupidly in love with the man writhing under him. There's no holding back, not now.
"Take it, gonna fill ya up," he groans, sliding his hand down Kiyoomi's back and holding him down as he pushes as deep as he can go. "F-fuck yeah, gonna come in yer pretty little cunt right fuckin' now."
Atsumu's orgasm hits him hard and deep, cock throbbing and hips trembling as he empties himself inside Kiyoomi. It seems to go on forever, his groans of pleasure turning hoarse, before his body finally relaxes and he has to steady himself on Kiyoomi's hips to stay upright.
"Oh my god," Kiyoomi says after a beat of silence, and then they both erupt into giggles.
"Fuckin' hell," Atsumu chuckles, carefully pulling out and collapsing next to Kiyoomi. "Don't think I've ever come that hard in my fuckin' life."
"That was incredible," Kiyoomi says softly, eyes still glittering with laughter as he settles onto his side and pulls Atsumu close. "I ought to tie you up more often."
"If I can fuck ya like this afterwards, it's a deal," Atsumu says, kissing Kiyoomi's nose, his flushed cheeks, his bitten lips. "Goddammit Omi, I love ya so much. Can't believe I'm so lucky as to have ya for life."
"I love you too," Kiyoomi says, suddenly a little serious as his hand cups Atsumu's jaw. "I'm yours until the end of time."
They kiss slow and deep, still a little out of breath and high on each other, and their hands quickly start to wander again. When long fingers brush over Atsumu's nipple, he curses and pulls Kiyoomi even closer.
"Shower, then round two?"
Kiyoomi raises an eyebrow. "Round two in the shower?"
"Fuck," Atsumu laughs, detangling their limbs and standing up on shaky legs. "Won't say no to that one, darlin'."
Kiyoomi takes his hand and is pulled up, giggling as he's pulled flush against Atsumu's chest. Their laughter follows them into the shower, into the rest of their honeymoon, and onto the rest of their lives.
