Atsumu loves to wear long shirts and hoodies around the house, and when he's feeling horny he'll happily wear nothing underneath. It drives Kiyoomi crazy, making him hard in seconds and teasing him until he's grinding his clothed dick against Atsumu's ass and pussy, gripping his boyfriend's hips like a vice and begging to be inside him, just for a second. And Atsumu always giggles, always has that sly smirk on his face as he coos; "Patience, Omi.".
And so Kiyoomi waits, hard and aching and with Atsumu's slick all over the front of his shorts, as his boyfriend goes about his day. He stands on his tippy toes to reach something on top of a shelf, raising the hem of his shirt up and showing off the delectable curve of his ass. He bends over to put laundry in the washing machine, exposing his cunt to Kiyoomi's hungry eyes. He passes by Kiyoomi on the couch, lightly brushing his cheek or shoulder as he goes, and Kiyoomi thinks he might spontaneously combust. Either that or come in his boxers like a teenager, he's not sure.
When Atsumu is finally done, he saunters over to Kiyoomi with a raised eyebrow. Kiyoomi moves lightning fast, shoving his shorts and underwear down in and hissing when the air hits his neglected cock. Atsumu smirks and cups Kiyoomi's jaw, bending down for a soft kiss.
"Good boy," he coos as he turns around, lifting his shirt up to show off his perfect ass. Kiyoomi puts his hands on Atsumu's hips, helping him keep steady as he settles on the couch, knees either side of Kiyoomi's legs and his pussy hovering over Kiyoomi's straining dick. Atsumu lowers himself down just a little, enough for the tip of Kiyoomi's cock to graze his wet folds. Kiyoomi groans as his hips buck involuntarily, chasing the tight heat he knows is just out of reach.
"Tell me what ya want, Omi," Atsumu says coyly, craning his neck back to meet Kiyoomi's gaze. "Use yer words like a good boy."
"I want to be inside you," Kiyoomi pleads, his trembling fingers digging into Atsumu's hips. "Please, Atsu, let me fuck you."
Atsumu hums, lowering himself a bit more and Kiyoomi chokes on a breath when the tip of his cock is kissed by wet heat. His hips shake as he tries to keep still, breaths shallow and head spinning. "Baby, please. "
"Please what, Omi?" Atsumu coos, lifting his hips up again and Kiyoomi almost whines at the loss of contact. "Ya know I like it when yer specific."
"Please sit on my dick," Kiyoomi pants, desperation seeping into his words. "Let me fill you up, baby, I want to so bad."
"Fine, since ya asked so nicely," Atsumu says, giggling as Kiyoomi's hips jump. "But no movin', okay baby?"
Kiyoomi nods and then groans as Atsumu sinks down for real, taking all of him inch by delicious inch. Kiyoomi pulls out all his willpower to not move, his thighs and hips shaking with the effort as his cock is enveloped in tight, wet heat. Atsumu sighs as he bottoms out, wriggling slowly for a few seconds before he stills completely. Kiyoomi bites out a curse, leaning his forehead against the nape of Atsumu's neck and breathing heavily.
"Stay still, Omi," Atsumu reminds him as he leans forward, showing off how flexible his hips are as his head, arms, and upper torso ends up resting on the coffee table. Kiyoomi squeezes his eyes shut as the tight heat shifts around him, but obeys and doesn't move. His hands hold onto Atsumu's hips like a lifeline.
"Gonna watch the game video coach told us to review," Atsumu says, and Kiyoomi's eyes open as Atsumu reaches for the remote and turns on the TV. "Ya better pay attention too, Omi, or ya will just have to watch it again later."
Kiyoomi nods, but then he realises Atsumu isn't looking at him. "I'll pay attention."
"Good boy."
Kiyoomi tries to be good, he really does. But after just over twenty minutes inside Atsumu's pussy, feeling his walls tighten around his cock and growing more desperate by the minute, Kiyoomi is on the knife's edge.
"Baby," he chokes out, his fingers spasming on Atsumu's hips as his boyfriend slowly sways them back and forth. "I can't... you feel too good, I can't-"
"What's that, Omi?" Atsumu coos, turning his head just enough for Kiyoomi to see his smirk. "I thought ya were gonna be good for me?"
"Atsu, I-" Kiyoomi begins, but is cut off by his own gasp as Atsumu clenches around him, his smirk widening. "Fuck, baby no, fuck I can't I can't-"
Kiyoomi shakes as he comes, hips stuttering in small, needy movements as he spills into Atsumu's cunt. His groans are broken and desperate, relief flooding through him as his cock spasms in the tight heat.
And then reality hits him and he knows what's coming. Shit.
"Such a shame," Atsumu hums, rolling his hips just once on Kiyoomi's oversensitive dick before lifting off him and turning around. Kiyoomi's eyes are glued to his crotch, watching his release slowly drip down Atsumu's inner thigh.
"I'm sorry, Atsu," he pants, twitching with the aftershocks. "You're so good, so tight, I couldn't hold back."
"Ya know what happens now," Atsumu says, grabbing Kiyoomi's jaw and tilting his head up to face him. "Ya know what happens when yer bad."
"I know," Kiyoomi nods, arousal stirring in his gut once again. "I'm at your mercy, baby."
Atsumu licks his lips and Kiyoomi can't do anything but surrender.
'Surrender' is a fitting term, Kiyoomi thinks an hour later, uselessly pulling on his restraints. He's cuffed to the bed, cock straining against his abs, his eyes glued to the scene in front of him.
Atsumu is splayed out in front of him, naked and gorgeous, head thrown back in pleasure as he fucks himself with a dildo. Kiyoomi's lost count of how many times Atsumu has come, pulling orgasm after orgasm from his shaking body with their large collection of toys. And Kiyoomi's not allowed to touch, not allowed to taste, not allowed to fuck. He just has to watch as his boyfriend's cunt clenches around the fake dick, hear his moans of pleasure as he comes again, his fingers frantic on his clit as the toy fills him up.
"Mmm," Atsumu hums as he comes down, a slow smile spreading across his face. "That was a good one. Which toy d'ya think I should use next, baby?"
"Me," Kiyoomi blurts out, tugging at his cuffs as his cock jumps and twitches with need. "Please, baby, use me however you want. Just let me touch you, please. "
"Yeah, ya think I should?" Atsumu smirks, crawling up Kiyoomi's body and hovering his dripping cunt just out of reach of Kiyoomi's cock. "Ya think ya been punished enough, hm?"
"Please, I'll be good," Kiyoomi begs, his hips jumping in a desperate search for heat, friction, anything. "I'll be so good for you baby, I promise."
Atsumu chuckles softly and kisses him. It's slow and tender but still sends Kiyoomi's body into a frenzy, his cock throbbing and his lips feeling like they're on fire. He whines low in his throat when Atsumu pulls back and strokes his cheek.
"Tell ya what, Omi," he says, reaching for his favourite clit sucker vibrator. "'M gonna sit on yer dick and make myself come one more time. If ya can hold out, ya get to fuck me however ya want. Deal?"
"Deal," Kiyoomi nods frantically, the thought of getting to feel Atsumu again making him dizzy with need. Atsumu smirks as he lines himself up and sinks down on Kiyoomi with a soft sigh. Kiyoomi's entire body jerks and he bites back a groan, focusing on his breathing as he's once again fully seated in his boyfriend's pussy.
"Be a good boy for me, Kiyoomi," Atsumu coos before turning the vibrator on and bringing it to his clit. Twin moans escape them and Kiyoomi loves that he can also feel the vibrations along with the rhythmic tightening of Atsumu's walls. He grits his teeth and focuses all his willpower on not fucking up into the amazing heat, to not simply thrust like an animal until he comes. He'll be good.
"Fuck, I love this thing," Atsumu moans, rolling his hips on Kiyoomi's cock in a way that makes him see stars. "Lucky for ya, 'm not gonna last long."
"Please," Kiyoomi almost sobs, not entirely sure what he's begging for but just needing to do it regardless. "Atsu, baby, please."
"'M close," Atsumu gasps, his hips speeding up around Kiyoomi's aching cock as he throws his head back in ecstasy. "Fuck, gonna come, ah! Fuck!"
They both groan as Atsumu comes, his cunt spasming around Kiyoomi and making him tremble with the effort to hold back. The orgasm is hard and fast and Atsumu soon deflates, peering down at Kiyoomi with a smile.
"Good boy," he purrs, and Kiyoomi preens at the praise as Atsumu reaches up and undoes his restraints. "Ya did so well for me."
Kiyoomi is just barely out of his cuffs before he grabs Atsumu and flips them over, panting as he buries himself in his boyfriend's heat once again. Atsumu looks up at him with a soft smirk, brushing curls from his face with gentle fingers.
"'M all yers, Omi. Give it to me."
Kiyoomi fucks him like an animal, hard and fast and feral as he desperately thrusts into Atsumu's soaking cunt. Atsumu clings to Kiyoomi like a lifeline and takes him beautifully, his entire body jostled by the force of Kiyoomi's hips. Kiyoomi knows he won't last, but that's not the point. The primal need to come in his lover, to claim him after being teased and denied, is his strongest instinct right now. And judging by the way Atsumu is moaning and thrashing under him, he's certainly not complaining.
"I love you," Kiyoomi groans, pressing their foreheads together as he fucks into Atsumu with everything he has. "So much, so fucking much, baby. "
"Omi," Atsumu moans, his cheeks flushed and his pupils blown wide. "I love ya too, keep goin' - fuck - just like that! Oh fuck, 'm gonna come again!"
Kiyoomi holds out, just barely, until Atsumu digs his nails into his back and cries out as he comes on his cock. It sends Kiyoomi over the edge, his hips stuttering before he buries himself completely in his boyfriend and rides out his long awaited release with a broken scream. A few tears run down his cheeks from how intense and incredible it feels.
They both fall asleep not long after, tangled up in each other as they nap for a good few hours. When they wake up Atsumu makes them a late lunch and they snuggle up on the couch to watch the game tape for real this time.
