Atsumu was obsessed.
In as loving and totally normal a way as possible, he was obsessed with nearly everything about his husband over the past six months. His usually prickly Omi was softening in more ways than one.
Omi's scent, the fresh smell of hydrangea and lily, now let out notes of cinnamon and crisp autumn air that were unmistakably Atsumu . His black curls were feather soft and shiny, as was his smooth skin.
("Omi-kun, yer glowin'!" Atsumu would say.
"Shut up." Omi would bluntly reply)
But no, Atsumu's fawning continued. The bigger Omi got, the more obsessed (annoying) Atsumu became. He couldn't start a practice without stinking up the locker rooms with his scent and gushing about how cute Omi looked, all rounded and soft.
He snuck a million candids of Kiyoomi in idle moments when he rubbed his tummy, smiling and mumbling things to their son and daughter when he thought Atsumu wasn't looking...and more than a few when he was absolutely aware, the grimaces on his face in the photo making that obvious.
And of course, he was perfectly attentive to Omi's every whim and need, no matter how silly or sudden. Atsumu Miya was nothing if not willing to spoil his husband ("because I'm yer alpha!") Even to the point where Omi was a little frustrated by his attention...sometimes.
Mostly, Omi had become more clingy with each passing week. And needless to say, sensitive. Something Atsumu was becoming increasingly addicted to.
Let it be known that Sakusa (Miya) Kiyoomi had never been a crier. To the point where Atsumu doubted he even had tear ducts.
He didn't cry when Atsumu first told him he loved him.
(Replying, instead, with a blunt "Oh. I love you too.")
He didn't cry when Atsumu proposed (in a rather unromantic location, to be fair. Kiyoomi's first choice probably wouldn't have been in front of a 7/11 at midnight.)
He didn't even cry at their private beachside wedding (though Atsumu would swear he got close that time.)
It wasn't that Atsumu wanted to make Kiyoomi cry, of course not, but well, it was like the white whale in their relationship. Something Atsumu chased if only to prove that it existed.
And to think all it took to see that mythical phenomenon was simply to knock Kiyoomi up! Really, Atsumu would later say with a smug fox-like grin, he should have tried that a long time ago. Because Kiyoomi had become downright emotional .
Well, emotional by Omi standards. Atsumu had read that your average omega became clingy and sensitive during pregnancy, and that moods could switch on a dime. He expected Kiyoomi to be as volatile and snippy as Rintaro was when he and Samu were expecting, but no. God was on Atsumu Miya's side.
Omi had mood swings, sure- but they tended to swing hard between VERY horny and stupidly weepy. Two things he was very happy to deal with. Even when he came home from a particularly tiring practice and was pulled into their bedroom before barely taking a step into the genkan, the entire house absolutely reeking with the cinnamon-noted scent of hydrangea and lily, and held down as Omi rode out that mood with shocking desperation.
(All the while glaring frustratingly down at Atsumu, who would lay there blissed out with his hands behind his head.)
The first time he caught Omi weeping had been over a leaf. A small, browning leaf on his favorite plant that he forgot to prune exactly once. ("What kind of parent will I be if I can't even take care of a plant?" He'd whimpered, voice trying and failing to remain steady.)
The second time had been over a singular spoon left in their otherwise spotless sink. ("I'm letting my house fall apart..." He choked out, turning immediately away from a cooing Atsumu who had to repress his smile at the sight.)
The third time had been in a restaurant when they were out with Motoya, and Omi, five months pregnant with twins that he was, found himself stuck in the booth and unable to move without the table being moved first. ("I'm never leaving the damn house again." He'd sobbed, especially as Atsumu failed miserably at containing his cackle.)
That was now three (3) whole times he'd seen his beautiful, very hormonal husband cry in their whole relationship, all in the span of six months. It made Atsumu's heart and ego swell with something even beyond an alphas natural pride at the thought of getting to bring out that side of the prickly, blunt jerk that was his husband. And as he now opened up the door to their home, gym bag heavy in hand after his last pre-paternity leave practice, it was immediately clear that he would be facing Omi Weeping Incident number four.
Atsumu was greeted by the overwhelming scent of a hydrangea in bloom, notes of cinnamon and spice wafting below the surface. He took a deep breath— ahh . Kiyoomi was in a mood. Refreshing as the scent was after a long practice, Atsumu could still taste the unmistakable tones of frustration and melancholy emanating from his mate like a cheap, miserable cologne. He shifted the heavy gym bag on his shoulder and tried to imagine what could have set his husband off this time. Really, history has shown that it could be anything.
It was quiet at first, as Omi tended to be when he cried. A very soft weeping almost overtaken by mortified groans.
“Omi-kun? Baby?” Atsumu toed off his shoes in the genkan, lingering there for a moment as he waited for a reply. “Babyyyy?”
“Don’t come in here.” A wobbly voice drifted from the direction of their living room, and Atsumu couldn’t help the fond grin pulling at his lips. “Go Away. Die.”
“Psh. Don’t ya think that’s a bit unprovoked, Omi?”
“It’s very provoked,” Kiyoomi sniffled. “This is all your fault.”
He ignored Kiyoomi's plea and followed the soft weeping to the next room, where he found his husband sitting on the floor, wearing one of Atsumu's hoodies, legs spread out in front of him. The petulant little pout he wore reminded Atsumu of their niece, Osamu and Rintaro’s daughter, and the silent tantrums she would throw every time someone dared to tell her no.
Kiyoomi immediately tried to turn away and hide his face. "I said go away and die."
"And leave ya alone with two kids, completely Atsumu-less? Nah." Atsumu's smile, smug as it naturally was, appeared genuine as he crouched down beside his husband. "Whatcha doin' down here, baby?"
Omi's face scrunched up. "Uh...I..." he sniffed, lips wobbling as he tried to explain the scene. His hands rested on his belly, still soothing in their motions. "Uhm...I dropped my, I dropped my phone."
He motioned toward the corner, where lo and behold his phone rested upside down by an end table.
Atsumu bit his lip. "That's it?"
"'That's it'?" Kiyoomi glared sharp enough to leave Atsumu bleeding. "I dropped it on the floor and tried to pick it back up, but...but..." His nostrils flared as a new wave of tears broke through. "I couldn't bend over far enough to get it. And then I remembered I haven't mopped the floor yet this week-"
"I told ya I’d do that!"
"Shut up, I'm not done." Kiyoomi sniffed again. "I haven't mopped the floor yet this week so it's filthy, my phone is filthy. And we're out of lysol wipes, but I couldn't even text you to pick more up."
"..."
"...I'm done now."
"...Omi-Omiiiiiiii." Atsumu couldn't help himself. Seeing Omi slumped over in one of his hoodies, hands on tummy, eyes red and puffy from crying over something extremely silly...goddamn it. "You're so damn cute, ya know that?!"
"Me being an irrational mess is CUTE to you?!" Kiyoomi grimaced in disgust when Atsumu grabbed his face, wiping the tears away before kissing all over his cheeks and nose. "You're disgusting. You caused this. Die."
"Nope! Too late, I'm fawnin' over ya!"
"Get my phone, damn it...!" The anger in his tone died down as soon as Atsumu placed his wrist under his nose, filling Omi with the soothing scent of pumpkin spice and autumn crisp. He sniffled again. "That's not fair..."
"Feels better though, don't it?" Atsumu grinned, especially as Omi followed that scent, refusing to part with Atsumu's wrist. "There, there. It ain't a big deal, Omi-kun. I'll wipe down yer phone and make ya a nice dinner and then fuck yer brains out until ya forget what you were ever cryin' about, okay?"
"You're sick. I'm in an emotional state and that's what's on your mind?" Of course, as he said that, Kiyoomi was rubbing Atsumu's wrist up his face, cheeks beginning to glow red. Atsumu’s head started to spin as the unmistakable scent of arousal filled his senses.
That was another thing- when Omi cried, it was always followed by the mood pendulum swinging sharply back to horny.
As if on cue, he tugged Atsumu down closer and shoved his face into his neck. He teethed and kissed at the exposed skin above his collar, all the while still grumbling "You're the worst. You're a pig. You're..." Through his own protests, Kiyoomi climbed into Atsumu's lap, continuing to kiss his neck as he pawed desperately at Atsumu’s t-shirt. Thankfully, he couldn't see the euphoria blooming across Atsumu’s face, threatening to overflow into something dangerously close to smugness. Ah, hell. He could tease Kiyoomi later. For now, he needed to slip out of his shirt before Omi ripped through the fabric himself. “ Hahh , Atsumu…”
Shit. Kiyoomi whined, purring his name, begging like Atsumu was the only balm his body ever needed. The uncharacteristic lilt in his tone rippled like static under Atsumu’s skin. He savored the sound, knowing full well that Kiyoomi would deny he ever talked so shamelessly when he was back in his right mind again. His scent, his movements, his voice, everything pointed to his inner omega taking front seat in his current need for Alpha, Alpha, Alpha . Kiyoomi had absolutely no shame, no inhibitions as he pulled the shirt over Atsumu’s head, and Atsumu came face to face with his black, burning stare and flushed cheeks.
“I’m here, baby, I’m here.” He snickered, trying to reassure his desperate mate as Kiyoomi pawed at his bare skin. “What do you want from me, hm? You want me to make you feel better, Omi-kun?” Now it was Atsumu who leaned forward, nuzzling his nose against Kiyoomi’s neck as his senses drowned in the heady scent of arousal. Kiyoomi swallowed. Atsumu could feel his body tense up.
“I need…” Kiyoomi was practically panting. “I need you to…”
“Need me to what, baby?” Atsumu couldn’t contain his smarmy tone, nor his shit eating grin as sharp canine teeth ghosted over Kiyoomi’s skin. “You need alpha to-- OW OW OW !”
His scalp screamed for mercy as Kiyoomi pulled his head back by the bleached roots, forcing Atsumu to stare back into the eyes of desperation: “I need you to do what you said you would. I need you to fuck me. I need you to fuck me so hard I can't breath because your ramming your cock deep enough to hit my throat. Then you’re going to fill me with your knot like I’m in heat and my damn body is begging for you to split me in half. That’s what I need from you. Alpha .”
As he stared gaping back at his husband, Atsumu didn’t know what turned him on more-- Kiyoomi’s words, or the blatant annoyance he said them with. Either way, his blood was singing, and his alpha rumbled at the prospect of fulfilling Kiyoomi’s every whim and desire.
“Omi…” He licked his lips, shock quickly melting into a wicked grin. Kiyoomi let go of his hair, eyes boring into each other as he shifted off of Atsumu’s lap. Nothing short of a challenge. That was the nature of their courtship even after marriage. “Wrap your arms around my neck and bend your legs.”
Kiyoomi only hesitated for a moment, his dark glare melting back into the pout it started from. “We’re not doing it on my rug.”
“I know, I know, ya don’t gotta remind me.” Atsumu wrapped one arm behind Kiyoomi’s shoulder, the other under his knees as he managed to rise into a low squat. “Hold on tight, ‘kay?”
“What?! Are you crazy? Atsumu.”
“You think I can’t handle ya like this, baby? They don’t call these thunder thighs for nothin’.” His grin was as bright as it was toothy. “I bench more than yer body weight every day.”
“Atsumu I swear --” Kiyoomi held on tight as he rose, heart jumping into his throat. “Don’t. Drop. Me .”
Atsumu could only give a huff of a laugh as he took in a deep, purposeful breath through pursed lips. Amateur hour , he thought. The voice of Iwaizumi Hajime drifted in the back of his mind, firmly reminding Atsumu to lift with his legs instead of his back and to not forget to breathe. His thighs flexed, and the burn was downright addicting as he managed to stand up straight with all of his fellow Olympic athlete husband (plus the extra pregnancy weight) gathered in his arms.
“WOOO!” He laughed, breathing hard as he hugged Kiyoomi close. “Whatcha think of that, Omi-Kun?! Ya think an alpha like me can’t carry his whole family in his arms?” His husband didn’t respond. Instead, Kiyoomi practically melted against his chest, hand flat against flexing pectorals. There was his omega again. The bedroom was a short walk away-- a blessing really, since Kiyoomi’s arousal had suddenly become so overwhelming it made Atsumu light headed.
“Atsumu… Alpha …” Kiyoomi whined, purred , refusing to let go of Atsumu even as he was placed into his neatly kept nest. “ Please touch me…”
“I’m tryin’, baby! Ya gotta let Alpha undress ya first!” While Atsumu laughed, Kiyoomi glared, his sudden annoyance enough to lift the hormone induced haze long enough for Atsumu to make his escape. “Goddamn…Look at ya. Is this what I do to ya, Omi-Kun?”
Kiyoomi was laying flat on his back, breath shallow, face flush and hot through a half-hearted glare, his black curls sticking to his forehead. The hoodie he wore looked downright uncomfortable sticking to his sweat-slick skin. It rode halfway up his belly, revealing the bump that gave him so much grief and Atsumu so much joy. And then there were his quickly-kicked off sweatpants, which did nothing to hide his hard-on.
Atsumu’s heart was fit to burst at the sight.
“You look proud of yourself.”
“I am proud of myself, now that ya mention it!” Atsumu was all smiles as he stepped out of his pants and boxers, letting his erection shamelessly hang free. “‘I never want kids, Atsumuuuuu . Stop looking at me like that Atsumuuu .’” He crawled slowly back on the bed and over to his mate, grabbing the hem of Kiyoomi’s hoodie. “‘Just because I’m an omega doesn’t mean I have to act like one, Atsumuuuuuuu .’ That was ya, like, last year.”
Kiyoomi snatched Atsumu’s wrist. “People change their minds. I might change mine right now if you keep being annoying.”
“Oh? Will ya, baby? Will ya really?” Atsumu’s eyes were glinting as he twisted out of Kiyoomi’s grip. He dragged the tips of his fingers feather-light down the line of Kiyoomi’s body, starting from his belly button and stopping just short of the trimmed bush of dark pubic hair. “Every time we start, it’s you who can’t ever stop. You’re insatiable lately, ya know that?” Kiyoomi shivered under his caress. He may have opened his mouth to respond, but it was lost among the keening whines that slipped out the closer Atsumu’s fingers got to where he ached the most. “And I love it. Fuck , I love it when ya need me like this. I want to hear it again-- do ya need me, baby? Do ya want my cock? Want me to fill ya full?” His entire frame hovered over Kiyoomi, boxing him beneath without putting any undue pressure on his bump.
“Atsu…mu… hah. ” Kiyoomi gasped as soon as he felt a finger circle his hole. “A…”
“You’re drippin’ already. I bet it started before I even got home, huh? Ya poor thing, having to sit in your own slick waitin’ for Alpha to get back.” His lips brushed against Kiyoomi’s ear as he dropped his voice down to a whisper. “Don’t worry. I won’t be leavin’ ya any time soon.” His finger slipped in, eliciting a sharp gasp from Kiyoomi’s lips. “I’ll do anythin’ for ya, my Omi-kun. You don’t even have to ask, and I’ll worship ya.”
“A- Ah …!” Kiyoomi’s hips bucked up. “Stop teasing…”
“Why? Ya look so damn cute, though!” Still, Atsumu was a little merciful. He pistoned his finger in and out of Kiyoomi’s soaking hole, teasing the rim with a second finger and reveling in each needy moan from Omi’s lips. “Shit, if only people knew how much of a shameless, needy omega ya were behind closed doors. My prim little Omi, begging for my knot like a cock slut. I always said I’d turn ya into one.” As he spoke, his mouth traveled down Kiyoomi’s body, pushing up his hoodie in order to kiss over his chest. He tongued over a pert set of nipples, heart singing at the sound of Kiyoomi’s gasp. “That omega of yours is probably beggin’ to be let out. I can tell-- you ain’t talkin’ back.” Atsumu smirked, peeking up to meet Kiyoomi’s blown-out set of black eyes absolutely devouring him. Slowly, he went lower, nudging Kiyoomi’s legs open. “I’ll have ya cryin’ for me, baby.”
Kiyoomi clicked his tongue. Atsumu could feel the frustration, the desire in his scent thickening as he scrunched his nose. “Why don’t you do it then instead of just talking-- AH .”
The words were cut off, nearly choking out of his throat as Atsumu hooked his arms under Kiyoomi’s knees and pulled him further down to the edge of the bed. He didn’t give his omega even a second to breathe. Atsumu lapped his tongue over Kiyoomi’s smooth inner thigh, his teeth nibbling at the skin as he went lower and lower. The ever-growing bump hid Kiyoomi’s face from view, but it made no difference-- Atsumu could still hear his gasps, his whimpers, his little curses when Atsumu paused his movements just short of his ass. Goddamn , the scent of arousal was intoxicating. Kiyoomi’s slick was glistening, practically begging Atsumu to take the next step and drown himself and get drunk on the omegas flowery taste.
“O h . Oh god .” Kiyoomi’s hand clamped over his mouth so fast that Atsumu could hear the smack. It did little to muffle his cries as soon as Atsumu swiped his tongue over his hole in one long, agonizing motion. “Atsu-- AH! Fu…ck… ”
Atsumu decided that he was officially done teasing. Kiyoomi’s whining, combined with the taste of slick and sweat overwhelmed his senses, did more to awaken his inner alpha than if Kiyoomi was actually in heat. A low growl emitted from his throat as his tongue bullied its way inside his mate, reaching as far as he could past the quivering ring of muscle, all the while Kiyoomi’s back struggled to arch off the bed. Now there was a sight and sound that would live in Atsumu’s head rent free-- his very pregnant Omi writhing on Atsumu’s tongue, scent absolutely overpowering, voice cracking and sighing each time he swiped his tongue over and inside his needy ass. Atsumu grinned, continuing to lap at the seemingly endless stream of his omega’s slick.
“Is that good, baby?” He wiped his smiling mouth with the back of his hand, momentarily popping his head out over Kiyoomi’s bump in order to get a good look at his face. “Wanna come on my tongue first?”
“Ugh, huh ?!” The sudden lack of contact made Kiyoomi groan. His face, burning through to the tips of his ears, twisted into a deep, mortified grimace when he met Atsumu’s gaze, his omega shoved to the side in order to just glare a hole into his mate’s head. “Are you serious ?”
“I’m always serious when it comes to pleasin’ ya, Omi-kun.” His heart swelled at the sight of Omi trying and failing to prop himself up on his elbows. God, yer damn cute . “I’ll be honest, I just needed ta pop up and take a deep breath.”
“Wha--- mmmAAHHH .” Kiyoomi was flat on his back in an instant, no doubt startled by Atsumu going to town on his ass with more ferocity than before. “Atsumu- uuu… ” Atsumu could faintly feel his husband’s fingers grasping for his free hand, his hair, anything to ground himself as Atsumu’s tongue drew his needy omega back out. “Atsu…A…Alphaaaa…”
Yer damn right I am . The pheromones were going right to his head. He shoved his tongue in and out of Kiyoomi’s hole, making the most obscene slurping sounds his mouth was capable of in order to match the increased intensity of his husband's moans. He easily slid a finger inside, hooking it around Kiyoomi’s rim, stretching him out as easily as if it were their third round in one day.
“ I …”
A second finger, Kiyoomi’s voice was cracking.
“Hahh…M… More …”
A third finger had his toes scrambling for purchase.
“Ya ready for me already, baby?” Atsumu growled between open mouth kisses to Kiyoomi’s rim. “So damn easy…opened up for me beautifully. Did ya even wait for me to get back?” He lapped up a stream of his own spit sliding down Omi’s burning skin. “Did ya fuck yerself earlier? So desperate that ya took out one of yer old heat toys? Did ya scream my name, baby?” He sat up, keeping three fingers curling deep inside Kiyoomi as he admired his work. Cute cute cute . Times like this, Atsumu almost felt like they were still early in their relationship and discovering each other’s bodies for the first time. Yet even the thousandth time had him completely enamored. With a laugh, he whispered, “My poor Omi-kun.”
“Sh…I… HAHH! ”
There it is . Atsumu licked his lips, eyes prideful and widening as he watched Kiyoomi grind against his fingers. The pressure on his prostate had Kiyoomi gasping for air, mouth hanging open, eyes squeezed shut. Beautiful . “Whatcha tryin’ to say? Can’t get the words out? My fingers fuckin’ ya too good? Look at me, baby.”
“Atsumu…” Kiyoomi’s lips quivered, and for a moment Atsumu worried he may have actually begun to cry again-- in pleasure, of course. The alpha would make damn sure of that. “Atsumu, I…I did. I did.”
“Did what?”
Tell me. Tell me how badly ya need me. Miya Kiyoomi, tell me you’re mine .
“F…” His mouth momentarily flattened into a line, and Atsumu could see the deepening crease in his brow. It must have been embarrassing to admit. Atsumu was counting on it. “F-Fucked myself. While you were gone. I…I missed you so much--”
His grumbling voice was choked by sudden emptiness. Atsumu pulled his hand away in a flash, wiping it idly on the sheets before leaning over and stealing Kiyoomi’s breath in a kiss. Kiyoomi didn’t resist his tongue. He opened up for Atsumu, inviting him to lick inside of his mouth and just kiss him silly until he was gasping for air.
“Omi,” Atsumu whispered against his lips, suddenly aware of the hoodie still between them. “Omi, my Omi. You’re so…” He wanted so badly to lay on top of his husband, to press his weight down and smother him in his scent. Kiyoomi always loved that-- for such a naturally standoffish and prickly guy, Atsumu had learned early in their relationship just how much Kiyoomi could cling.
“You’re warm, I guess,” He’d say. A weak excuse. Atsumu never felt the need to press him further.
But right now, something was in the way. So Atsumu settled for propping himself haphazardly over Kiyoomi like he was going down for a pushup, long enough to simply watch,. to hear Kiyoomi’s shaking, needy breathing as he chased after Atsumu’s lips. Eventually, he had to see everything. That damn black hoodie hid Kiyoomi away for far too long, and he pulled it over Omi’s head so fast that he had no time to protest.
“You’re so damn beautiful, ya know that?”
Kiyoomi’s face scrunched, conscious of the exposure, his hands resting on his belly. “Even like this?”
“Are ya kiddin’? Especially like this.” With one more dizzying kiss, and a kiss over the peak of Kiyoomi’s bump, Atsumu crouched back on his heels and lined himself up at Kiyoomi’s slicked-up entrance. The glide in was easy-- Atsumu pressed inside in one snap of the hip, his skin slapping against Kiyoomi’s loud enough to match his mate’s shout. “Fuck, baby…”
“Please… pleasepleaseplease ,” Kiyoomi threw his head back against the sheets, his hands blindly reaching out for anything, any part of Atsumu they could grab. “More, please, more, I--”
“You want Alpha’s knot, I know.” His smile was as smug and fox-like as it was fond. “So spoiled.” It began with a languid, steady roll of the hips. Atsumu kept his eyes locked on Kiyoomi’s face, marveling at the way his tense expression softened with each slow thrust. His mouth fell agape. “ Fuck ,” Atsumu growled. “I mean it. Yer perfect.”
Kiyoomi didn’t respond. Instead, he began to roll his hips in tandem with Atsumu despite the strain on his back. That’s my Omi-kun , Atsumu thought. Can’t do anythin’ halfway . The pace climbed with a subtle, desperate rhythm between them. Atsumu didn’t know when he started heaving so hard. His own body was burning with each thrust, each wet slap of skin. He paused for a moment only to shove a pillow beneath Kiyoomi’s hips and sharpen the angle.
“ HAH…MMMAHHH… ” Kiyoomi scrambled forward, throwing his long arms around Atsumu’s neck. “Atsumu…Alpha, please…”
“That’s right, let me hear ya-- ah…fuck , ya feel incredible.” The new angle was downright delicious. He managed to cradle Kiyoomi’s back, helping his body roll and fuck itself on Atsumu’s swelling cock. What he loved more, however, was how close their faces were, how Kiyoomi seemed just as desperate to kiss him as he was to get off. The ghost of a scar was visible at the junction between his neck and shoulder. Teeth marks, remnants of whispered promises followed by a deep, physical bond that made them one body and soul. The sight of it made his blood rush to his cock as thoughts of again, again, it’s too faint, he needs to be marked again and again overwhelmed his mind.
“Atsumu,” Kiyoomi whispered, whining as his rim began to be stretched wider. “Atsumu. So good. It’s so good…”
“And you, hah, you take my cock so well.” His nose nuzzled against his neck, over the faint mating mark that called out for his attention. The base of his cock grew, shivers running through his spine as it caught on Kiyoomi’s rim. Any moment now. His mind hung on by a thread as he drove further into his husband, pounding and pounding against his prostate. It was impossible to see Kiyoomi’s cock at that angle with his belly in the way, but he knew it was leaking and aching. He could feel precum sticking across his abs. “So well, so good, my Omi, my omega, ah, fuck .”
Kiyoomi's head lolled back, senses smothered by the alpha’s pheromones, by the cock nailing his prostate over and over. Atsumu registered a line of drool falling down his mate’s cheek, doing nothing to help quell his more animalistic instincts. God, it was impossible not to slam into him with every ounce of his strength-- but not now, not when he was carrying his kits. Our kits . Omega is carrying our kits.
That thought alone carried him past the threshold, his knot swelling so agonizingly full that Kiyoomi shouted. Still, he took it. He took it so well, so damn well, his rim tightening around the base as he was filled full of Atsumu, Atsumu, Atsumu.
“Ah…AH…” Kiyoomi was rocking himself back and forth, hugging Atsumu for dear life as he fucked himself over the edge. As the knot continued to pour into him, the edge neared, and finally, finally--
His scream was sharp. As sharp as Atsumu’s teeth sinking into his neck.
A thick rope of cum shot up against Atsumu’s abs, some onto Kiyoomi’s thighs, and Atsumu felt drunk off the taste of sweat, seed, and slick. Mine, he thought, spreading his fingers through the hot spend on Kiyoomi’s thigh. He was so far gone, he didn’t think twice about cradling Kiyoomi’s cheek with the dirty hand and keeping them face to face as he rode out the orgasm. All mine. My mate. My husband. My Omi-kun.
It could have been seconds, it could have been minutes-- hell, Atsumu wouldn’t have minded if it was hours-- but eventually, Kiyoomi’s heavy body grew tired once the orgasm ebbed away. He gracelessly flopped backwards onto the bed, heaving deep breaths as he sank into the sheets. “Huh…Mm.” He cleared his throat. “Wow.”
“Wow,” Atsumu repeated, hovering over Kiyoomi’s form, wiping the spit from his mouth. The euphoric high was starting to make him light headed. “Mm. Heh.” His body burned, but he shivered. His fingers grazed against Kiyoomi’s rim where it clenched around his pulsing knot. “Lookit that. It’s still goin’. We’ll be stuck for a while.” Thank god.
At first, Kiyoomi actually smiled. It was small, sweet, content even--that was until he registered several things. First, was the sticky cum on his cheek. He smacked a hand over the spot and clicked his tongue. “Atsumu. Ew .”
“I’m sorry, baby! I didn’t mean ta! Ya know I’m a beast in the sheets, my mind just goes blank! And ya just looked so damn pretty!”
He clicked his tongue again, face contouring into a disgusted scowl. “You’re unbelievable-- ugh .”
Kiyoomi reached down, his fingers meeting the cum that was apparently so abundant, it leaked past Atsumu’s knot. And boy, did it keep leaking. Disgust morphed into horror, and for a second Atsumu worried that the state of their sheets would send him into the second crying incident in one day. Of course, Atsumu didn’t dare point out to Kiyoomi that, well, it was kind of his fault, really. That Kiyoomi rarely ever asked him to wear condoms anymore, or even set down towels. Not since the pregnancy started, and his libido was so high that they would probably go through several loads of towels in a week-- but he didn’t wanna push his buttons when their bodies were stuck together and he smelled so damn satisfied.
So instead, he smiled, eyes half-lidded and overflowing with love as he leaned over and kissed his nose. “Why don’t I do the laundry for ya first thing tomorrow, okay?”
“And make me sleep in this? No. We’re doing it now, I don’t care if we’re still locked. I need to bathe, too. I’m… sticky .”
“Baby, that’s insane! You’d take apart yer nest over a little cum?!”
“‘A little’?” Kiyoomi was about to say more, but in one quick motion he was pulled onto his side and tightly into Atsumu’s arms. The cock in his ass shifted as well, making him tense up from the pleasure-pain. “ Atsumu .”
“Omi-Omi.” He batted his lashes. “Don’t be mad at me. Not after dryin’ yer tears and rockin’ yer world. Besides,” He whispered, running his hands gently up and down Kiyoomi’s belly. “It’s bad for the babies. Ya wanna yell at me in front of the kits?” He spoke directly into Kiyoomi’s ear. “What if ya go into labor?”
Kiyoomi’s hyper flexible wrists were like a whip against his skin, and Atsumu couldn’t help but laugh as he grabbed the offending hand and brought it to his lips.
“You’re deranged,” Kiyoomi grumbled, a huff of a laugh, not a single drop of venom in his voice. No, if the fresh and clean scent of hydrangea was anything to go by, his heart was fluttering as fast as Atsumu’s. The scent mixed perfectly with cinnamon and crisp autumn air. “And, uh, sorry? For jumping you out there.” His face twisted again. “You didn’t even get to shower, eugh .”
“Eh, ya don’t think I’m used to it by now? Besides, I’m on leave.” He pulled Kiyoomi close, back to his chest, knot still full inside. “I’ll make sure ya don’t miss me ever again.”
