Dazai hears the door open and slam shut. He has a greeting ready on his tongue when the smell hits him and he turns around to look over the couch

at Chuuya. His mouth waters just a little bit, but he keeps his composure.

Chuuya is rumpled and sweaty and flushed as he leans back against the door. Dazai smirks.

“Chibi’s rut came early? How unprofessional.”

Chuuya looks at Dazai with a heavy-lidded glance, mouth parted

and panting. His gaze is like wildfire and Dazai swallows thickly, tilting his neck to the side slightly as he keeps his gaze locked with Chuuya's.

Chuuya doesn’t need more than that to stalk forward. When he reaches the couch he grips Dazai’s hair, tilting his head further to

the side and bites down on the mating bite he left there years ago, body relaxing as he licks over Dazai’s neck, leaving nips and kisses over Dazai’s scent glands.

Dazai’s eyelids flutter shut as he lets Chuuya scent him urgently. Eventually, Chuuya climbs over the back of the

couch, settling in Dazai’s lap. He nips at the Omega's bottom lip before kissing him, growling when Dazai laughs. “Chibi’s so /eager/.”

“Fuck off,” Chuuya snaps, even as he kisses Dazai’s jaw, grinding his hips against him. “When’s your heat start?” he asks as he tugs at

Dazai’s earlobe with gentle teeth. Dazai hums, purring gently as he runs his hands up Chuuya’s back.

“Not for another two days.”

Chuuya whines softly at that, biting down on Dazai’s clothed collarbone. Dazai’s fingers tangle in Chuuya’s hair, pulling his face up to press

against his throat again. “Don’t worry, baby, I’ll take care of you.”

Chuuya sucks bruises into Dazai’s skin desperately, absently grinding his hips. Dazai smirks, feeling Chuuya’s cock straining in his slacks as he jerks against Dazai’s leg. He pulls at Chuuya’s hair after a

while, tilting the Alpha’s head back and exposing his neck. Dazai leans up, sinking his own teeth into Chuuya’s matching mating bite.

Chuuya usually smells /just right/ since Dazai doesn’t let him leave the house without a thorough scenting, but right now he smells /off/.

It’s faint, but Dazai doesn’t /like it/. He noses at Chuuya’s scent glands, making soft, satisfied sounds as Chuuya’s scent starts to go back to normal.

He leans back and preens slightly at his work. His mild distraction is just what Chuuya needs to slide off of Dazai’s legs,

shift onto the couch and then physically lift the Omega up and into his lap.

Chuuya makes quick work of unbuttoning Dazai’s shirt, nearly tearing it off as he slides it over his shoulders. He nuzzles against Dazai’s collarbone, breathing him in and nipping at flushed skin.

“You’re not wearing your bandages,” Chuuya rumbles, kissing over Dazai’s chest, hips still rolling against the Omega’s ass. Dazai chuckles, fingers flexing in Chuuya’s hair. He doesn’t pull just yet as he watches Chuuya mouth at his skin with keen interest.

“Oh? You’re still

with me, Chibi?”

“Sorta,” Chuuya says, words a little slurred and his eyes hazy when he looks up at Dazai through his long lashes.

Dazai pulls his head back and kisses him slowly, not letting Chuuya deepen it, just giving him what he wants and nothing more. Chuuya whines,

trying to /take/ what he needs and Dazai bites his bottom lip.

“/Behave/,” Dazai says and the little whine cuts off as Chuuya looks up at him, waiting and patient. “Good boy.”

The Alpha’s pupils dilate at that, breath picking up slightly. Dazai tilts Chuuya’s chin up with

his free hand and smirks. “I had a feeling you’d be early, so I got ready for you.”

Chuuya growls, hands moving down to grip Dazai’s ass and /squeeze/. Dazai sighs with a little smile, nodding as Chuuya latches onto his chest again, leaving bites and kisses as he holds Dazai’s

ass tightly, making needy little noises. His eyes are hazed over completely now, possessively grabbing Dazai’s body and grinding his hips up against his mate.

“/Mine/,” he growls.

“Mm, yours,” Dazai whispers, moving his hips with Chuuya’s. “I love it when you get like this,”

Dazai says, letting Chuuya latch onto his mating mark again. “How bad do you want it, Chuuya?”

Chuuya growls, bucking his hips as if to illustrate his point as he sucks at Dazai’s skin, watching the bruises bloom there with satisfaction. Dazai yanks on his hair, body still

above him as he looks down at Chuuya with terse indifference. “I asked you a question.”

Chuuya looks at him pleadingly, squeezing his ass and panting.

“/Osamu/,” he breathes. Dazai kisses him, soft and chaste even as Chuuya tries to nip at his lips.

“Tell me how bad you

want it.”

Chuuya pants, cheeks flushed and hair messy and twisted in Dazai’s fingers.

He makes such a pretty sight, but Dazai wants to tease him. To watch Chuuya swallow desperately, baring his teeth slightly and digging his fingers into Dazai’s ass. “Come on, baby, don’t you

wanna fuck me?” Dazai whispers, watching Chuuya’s body react. His fangs are bared, his eyes focused and hungry and desperate. He nods and Dazai smiles sweetly. “/How bad/?”

“/Bad/,” Chuuya growls out. Dazai loves seeing him like this, desperate out of his mind, with one goal.

One desire. It makes him feel powerful to tease him and deny him that /one thing/.

“You can do better than that.”

Chuuya growls again, fingers gripping Dazai’s waistband and tugging. He buries his face in Dazai’s neck and he wants it /so bad/. He opens his mouth,

forcing the words out so he can /get it/.

“Wanna fuck you until you forget your name,” Chuuya says, rough timbre vibrating against Dazai’s throat. Dazai sighs softly, nodding. “‘Til all you can think about is /my knot/. Over and over because you’re /mine/.”

Dazai hums, a low purr in his chest that makes Chuuya go boneless against him, mouthing at Dazai’s throat. Dazai gently runs his fingers through Chuuya’s hair, scratching at his scalp as he speaks.

“Then beg for it.”

“/Please/,” Chuuya murmurs immediately, eyes still fluttering as Dazai keeps purring.

“Please what?”

“/Osamu/,” Chuuya whines, his cock straining against his slacks. “Please let me fuck you.”

Dazai hums, tilting his head as Chuuya licks up his throat and letting out a

strangled moan when Dazai grinds down against him.

“Why should I?”

“I’ll make you feel good,” Chuuya says, voice high and desperate. “I promise I’ll make you feel /so good/.”

“I don’t know…” Dazai says, pouting his lips because he knows it drives Chuuya crazy. The pit of

boiling want and desperation is getting hotter in his stomach, but he wants to drag this out.

Their cycles are usually so in-sync that he never gets to play with Chuuya like this, always so out of his own mind that all he wants is to take what he needs from his Alpha until

he's satisfied. “Have you really /earned/ it, Chuuya?”

“Please, please,” Chuuya whispers, hands slipping into Dazai’s pants to cup his ass, squeezing the flesh and spreading his cheeks.

His fingers brush the plug inside his mate and he groans, hips bucking instinctively.

“Osamu, baby, /please/. What do I need to do?”

Dazai grins, all sharp teeth and a rush of excitement.

“Take me to bed.”

Chuuya sits up, only waiting for Dazai to wrap his legs around his waist before he stands up carrying the gangly Omega to their bedroom. Dazai laughs as

Chuuya sets him down gently, hands moving to Dazai’s pants. Dazai tuts, reaching down to grip Chuuya’s hair.

“Not yet, Chibi,” he chides. “If you can’t behave I’ll muzzle you.” Chuuya stills at that. The muzzle is fun /normally/, but right now all he wants to do is kiss and bite

every inch of his mate’s body. He looks up at Dazai, pleading. Showing him how good he is.

Dazai smiles. “Strip for me.”

Chuuya stands up, unbuttoning his vest and nearly tearing off his shirt as Dazai's soft, smokey scent fills the room. Chuuya’s teeth /ache/ to claim him when

Dazai looks up at him through his lashes, all demure smiles and flushed cheeks.

When Chuuya finally sheds his slacks, the release of pressure on his cock has him hissing through his teeth. Dazai’s eyes rove over his body appreciatively.

Chuuya steps forward, slowly crawling

onto the bed between Dazai’s legs, giving him time to push him away.

Instead, Dazai reaches up, finger hooking under Chuuya’s choker and dragging him forward into a deep kiss. Dazai’s knees bracket around Chuuya’s waist, moaning softly as their hips meet. Chuuya kisses him like

he’s drowning and Dazai is air, chasing his lips when he leans away.

Dazai smiles against him, sucking on his bottom lip. “Show me why I should let you fuck me.”

/That/ is something Chuuya is happy to do. He kisses Dazai for a while longer, languishing in the desperate

embrace before moving down. He finishes stripping Dazai’s shirt and trails kisses down scarred skin reverently.

“Mine,” Chuuya murmurs against him, leaving lovebites across Dazai’s chest. Dazai laughs, light and airy.

“Yours,” he agrees.

“Perfect for me,” Chuuya rumbles,

running his tongue over one of Dazai’s nipples before sucking it into his mouth.

“Oh yeah?” Dazai asks, a little moan escaping as Chuuya tugs his nipple with his teeth before moving to the other side.

Chuuya nods, one hand running lightly over Dazai’s ribs and the other

fumbling with his zipper.

“Everything I want. /Perfect. Mine/.”

Dazai smiles, even as it turns a little self-loathing.

“Even though I’m broken and can’t give you a family?” he asks, gasping when Chuuya kisses down his stomach, nipping at his hip bones. “You always said you

wanted kids.”

The growl that rips out of Chuuya’s chest is rough and vicious. He leans up, grabbing Dazai’s face tightly.

“Don’t fucking say that,” he snaps, eyes narrowed. Dazai’s chest heats up with affection as Chuuya kisses him. “You’re /my/ Omega and you’re /perfect/.”

Dazai’s eyelids droop, his scent getting stronger, sharper as he purrs in contentment.

“Prove it,” he whispers. Chuuya kisses down his stomach, eager to please. He takes Dazai’s zipper between his teeth and slowly tugs it down, licking over Dazai’s cock beneath his underwear.

Dazai keens, arching his back off the bed as Chuuya kisses his cock and slowly slides his pants down. “/Yeah/, baby,” Dazai breathes.

Chuuya’s body heats up at the praise, eager to get more.

“Make me feel so good,” Chuuya whispers, taking the band of Dazai’s underwear between

his teeth, pulling just enough to get a satisfying /snap/ when he lets go, relishing in the little hum that his mate gives him in return. “/Gorgeous/.”

Chuuya trails bites and kisses across Dazai’s hips, hands gripping his thighs tight. He slips Dazai’s knees over his arms and

licks his way up Dazai’s stomach, over his chest and settles with a sharp bite over Dazai’s mating mark.

“You’re annoying and petty and an asshole,” Chuuya growls and Dazai rolls his eyes. “But you’re /mine/. I don’t want /anyone else/.”

Dazai runs his fingers through Chuuya’s hair with a smirk before gripping the strands and pulling Chuuya’s head back.

“Then show me, baby. /Earn it/.”

Chuuya’s mind is swirling with need and he’s so hard he can barely think. He feels frustration building up and pouts down at

Dazai, baring his teeth.

“I /have/,” he snaps. Dazai’s eyes darken and Chuuya knows he was /so close/ but he’s so /frustrated/. He whines before Dazai even speaks, closing his eyes and leaning back into Dazai’s fingers in his hair.

Dazai pushes at his chest as he pulls his

hair, making Chuuya lean back on his knees.

“You haven’t earned it until I /say/ you have.”

“I’ll be good, Osamu. I’ll be good, I’m sorry,” Chuuya pants, lowering his gaze as Dazai keeps pushing him until he has to crawl off the bed.

“I know you will,” Dazai muses, eyes

darting down once before meeting Chuuya’s gaze again. Chuuya sinks to his knees obediently. “Because you wanna be my good boy, right?”

Chuuya nods, keeping his hands balled up in fists, waiting. He can be patient. He /can/. “Answer me, Chuuya.” Chuuya swallows thickly, tilting

his head to the side as he looks up at Dazai, who he sits on the edge of the bed.

“I wanna be your good boy.”

Dazai hums a lilting little tune before spreading his legs.
“Make me come until I say you can stop,” Dazai says softly. “Then you can fuck me /all night/.”

“All night?” Chuuya asks, eyes glistening even as his cheeks are flushed and he can’t seem to catch his breath.

His hazy gaze is desperate, but he knows how to make it stop if he needs it, so Dazai just nods with a sweet smile, massaging Chuuya’s scalp gently.

“Yeah, sweetheart, all night.”

Chuuya looks so eager, a sparkle in his eyes. He lifts his hands, hovering over Dazai’s bare thighs and looking up at him hopefully.

Dazai nods once and Chuuya’s scorching touch runs over his skin. His hands slide up, settling on Dazai’s hips

as Chuuya scoots forward on his knees until he’s seated between Dazai’s legs.

Chuuya’s nimble fingers tease the hem of Dazai’s underwear as he leaves kisses against his cock.

“Gonna make you feel /so good/.”

“Then /do it/.”

Chuuya bares his teeth, tearing Dazai’s underwear

off and Dazai rolls his eyes. “Always making a mess.”

Chuuya ignores him, pressing kisses over the head, preening under the sounds of encouragement Dazai makes.

He licks a long strip up Dazai’s cock, sucking on the tip. “That’s it, baby,” Dazai sighs, gripping Chuuya’s hair

and pushing his head forward.

Chuuya eagerly swallows him down, throat lax as Dazai fucks into his mouth. “Such a pretty mouth,” Dazai murmurs.

Chuuya hums, eyes fluttering shut as his body heats up, the coil of /need/ a rolling boil in his gut.

His dick /hurts/ and he’s not sure how long he’ll even /last/ at this point when does get to fuck Dazai, but with the sounds coming from Dazai’s lips, he can’t even worry about it.

He feels Dazai’s hand tighten in his hair, his heart speeding up in response. He’s /close/.

Chuuya is so good for him and he’s /close/.

Chuuya squeezes Dazai’s thighs, sucking and running his tongue over the underside of Dazai’s dick. “/Yeah/,” Dazai moans as he cums, trembling with aftershocks as Chuuya swallows and sits back.

Dazai smiles at him as he lays back against the bed, trying to catch his breath.

He nods toward him and Chuuya hastily climbs up, straddling Dazai’s waist, waiting. “What a good boy you are for me,” Dazai hums, holding Chuuya’s chin and pulling him down for a sweet kiss.

Chuuya groans into it, sinking into Dazai’s lips as affection and praise swirl in his muddled brain.

He doesn’t even notice his hips absently rocking against Dazai’s stomach until the Omega’s hand closes around his throat, light pressure on the vein beneath his fingers.

Chuuya stills, even though it’s /hard/ and the loss of friction nearly brings him to tears, but he manages it.

“If you wanna fuck me, you need to wait a little longer. You can do it, right? You can make me cum again, right, love?”

“Yes,” Chuuya gasps out, eyes rolling back in his head when Dazai squeezes just enough to make him light-headed. Just right. “Yes, I promise.”

“Good,” Dazai says, releasing Chuuya’s throat and kissing him again. “Then get to work.”

Chuuya kisses him deeply, pinching a nipple

and swallowing down the moan of pleasure Dazai whispers out.

Chuuya slides down Dazai’s body again, taking his time to kiss each and every inch of him, pampering him while he catches his breath.

He kneels between Dazai’s legs, sucking bruises into Dazai’s inner thighs.

One particularly hard nip makes Dazai’s knees jerk, squeezing Chuuya’s head as he moans.

Chuuya leans down, finding the base of the plug he felt earlier and licks from the end of the toy all the way up to the tip of Dazai’s dick.

He looks up and Dazai watches him, calculating.

When he doesn’t protest, Chuuya pulls the plug out slowly, watching Dazai shudder at the loss of that /fullness/.

Chuuya licks over his hole slowly before slipping tongue in just to hear the way Dazai keens, arching off the bed and squeezing his knees around Chuuya’s head,

which only drives his tongue deeper.

“/Fuck/, Chuuya, So good for me!”

Chuuya’s skin crackles at the praise, fucking Dazai with his tongue as deep as possible.

Dazai’s hips begin to rock down to meet Chuuya’s tongue and Chuuya moans against him, growling when Dazai whines,

squeezing his legs tighter. “/Just/ like that, baby. Such a /good boy/.”

Chuuya’s mind gets a little foggier as he tongue-fucks his mate boneless, loving the way Dazai drags himself down to meet each thrust.

He shouts when Chuuya’s fingers reach up to fondle his balls.

Dazai shivers, moaning Chuuya’s name as his orgasm crashes over him, but Chuuya doesn’t let up.

He fucks his tongue into Dazai relentlessly as his hand reaches up to grip his cock, pumping it even as Dazai groans.

Chuuya pulls away, replacing his tongue with two fingers,

sliding into Dazai’s body easily as he swallows down his cock again. Dazai gasps, gripping Chuuya’s hair, holding him still and fucking his hips forward roughly as Chuuya’s fingers curl just right and find that spot.

A growl rips out of Dazai’s chest, his hips speeding up as he

fucks Chuuya’s face mercilessly. Chuuya relaxes his throat and lets the Omega take.

His eyes tear up but he keeps pumping his fingers in and out of Dazai’s body, adding a third and spreading them out, just to draw out a little groan.

Dazai finally, /finally/ cums again, forcing Chuuya’s face flush against his hips as he rides out the orgasm.

Dazai releases Chuuya’s hair, purring contentedly and smiling at Chuuya who crawls up his body, cock flush against his stomach and twitching at the sight of Dazai

breathless and messy.

Dazai’s gaze drifts down and he frowns sympathetically.

“Does it hurt?” he asks. Chuuya is ready to shake his head, say that he’s /fine/ and he’ll be /good/, but Dazai cuts him off. “If you lie to me I /won’t/ be happy.”

Chuuya sniffs, knowing what that

means and swallows, nodding.

“Yes,” he says through clenched teeth. Dazai kisses him, hands rubbing over Chuuya’s shoulders comfortingly.

“You just wanna fuck me, baby?”

Chuuya nods again.

“Mmhm,” Chuuya gasps. Dazai digs his nails in.

“Such an obedient little thing,” Dazai muses, tilting Chuuya’s head to the side and biting his neck. “So patient for me, make me feel /so/ good.”

Chuuya nods along. He /is/ good and obedient and patient. So good for his Omega.

Dazai leans back against the bed, letting his legs fall open, that same demure expression on his face.

He reaches out hooking a finger in Chuuya’s choker again and dragging him forward to growl huskily in his ear. “Show me what a good boy you are and fuck me into the mattress

until I don’t remember my name.”

Chuuya pants, nodding and not needing to be told twice. He hauls Dazai’s legs up over his elbows and barely whispers out a “thank you, Osamu,” before snapping his hips forward and sliding all the way in.

A high-pitched whine sounds like it was

punched out of Dazai’s gut as he holds Chuuya’s choker /tighter/.

“/Fuck/,” Chuuya moans, hips already setting a bruising pace, finally inside his mate, fucking him the way he deserves.

Dazai takes his cock like it was made just for him. Chuuya whispers reverent praise into

Dazai’s throat, feeling the way the Omega’s gasps and groans rumble beneath his lips. “Mine,” he growls, eyes going blurry with lust and need.

The rut heats his skin and he barely registers the filthy things that leave his mouth as he fucks Dazai harder, faster.

Dazai’s legs

wrap like a vice around Chuuya’s arms and his heels dig into his back, squeezing him and trying to pull him deeper.

Chuuya has always been eager to please in bed, but like this he fucks like it’s his profession.

He kisses Dazai’s jaw under his ear, happy to let Dazai hold him

close by his choker. “Feels good?” he whispers and Dazai squeezes his legs tight again.

“So good, sweetheart. /Harder/.”

Chuuya grunts in response, slamming his hips forward faster, pushing Dazai’s legs further back, angling his hips /just/ right until Dazai’s fingers twist in

his hair and he moans, legs trembling as he tries to drag Chuuya’s hips back faster, chasing that all-encompassing pleasure. Chuuya doesn’t need to be told to keep fucking him /just like that/.

The bliss on Dazai’s face makes a feral part of him desperate to see /more/. To take

him apart piece by piece until all he can do is moan Chuuya’s name and beg for more. For his good boy to keep going /just like that/.

He just wants to hear Dazai telling him how good it feels to have Chuuya’s cock inside him and let Chuuya go for hours.

He wants Dazai to tell him /exactly/ how to fuck him and then come apart when Chuuya does it /perfectly/.

Dazai throws his head back, biting his lip and nodding as Chuuya keeps a relentless pace. His legs tremble in Chuuya’s hold, scrambling for purchase. He tugs Chuuya

up until the Alpha’s nose is pressed against his neck. The scene there is strong and heady and makes Chuuya a little light-headed. “/Bite me/,” he demands.

Chuuya’s mouth opens without him really meaning to and he bites down on the mating bite. He doesn’t break skin again, but

the pressure makes Dazai squirm and gasp out praise.

The bed slams against the wall with each thrust and Dazai’s eyes roll back in his head as he cums, squeezing impossibly tighter around Chuuya’s cock. His fingers are holding Chuuya’s hair in a vice grip, keeping him close as

he bites a little harder on Dazai’s neck.

Chuuya’s rhythm grows erratic and when he feels the knot begin to swell he lets out a dry sob as it locks them together. Chuuya’s hips rock slowly, riding out the aftershocks.

Eventually, his head clears and he collapses on Dazai’s

chest, soothed by the purring he feels there and the gentle hand running through the tangled strands of his hair.

“You’re /mean/,” Chuuya grumbles against Dazai’s throat. Dazai laughs, tilting his head to the side and nuzzling at Chuuya’s temple.

“/There’s/ my Chibi,” he says.

Chuuya huffs, rolling his eyes. “You didn’t tell me to stop. You /like it/ when I’m mean.”

Chuuya doesn’t argue because that’s /true/, but /still/.

“I thought my dick was gonna fall off before you let me fuck you.”

Dazai laughs, shaking his head

“Your dick would /not/ have

fallen off.”

“It /felt/ like it.”

Dazai shakes his head, arms wrapped tight around Chuuya’s back, enjoying the quiet moment together before Chuuya’s rut clouds his thoughts again. “Thank you,” Chuuya mumbles, sounding like he might doze off.

Dazai huffs out a laugh, shaking

his head.

“You don’t /actually/ have to thank me for sex, Chuuya.”
That earns him a lazy pinch to his side and a grumble.

“That’s not what I meant, asshole,” he says. “I mean for...taking care of me.”

Dazai sighs, shifting to rub his cheek against Chuuya’s, purring louder

as if to make a point.

“You don’t need to thank me for that either."

Chuuya just makes a noncommittal noise, wrapping his arms around Dazai’s torso and kissing his neck gently.

“You did it again,” he says.

“Hm?”

“You were going on about the /family/ thing again,”Chuuya says,

shaking his head. Dazai doesn’t respond, pointedly silent when Chuuya leans back just enough to look down at him.

Chuuya’s eyes narrow, rolling his hips slowly and drawing a gasp from Dazai, who looks up to glare at him. “I don’t care about that, Osamu.”

Dazai turns away, petulant again.

“Yes you do,” he says. “You’re just too good a person to say so.”

Chuuya’s teeth clack together as he clenches his jaw and growls. Something inside him aches when Dazai talks like that. When he blames /himself/ for something that was done /to

him/. He leans down to press their foreheads together, staring into Dazai’s big, brown eyes with determination.

“If I have you then I /don’t care/.”

“You want kids.”

“We’ll adopt.”

Dazai doesn’t seem to have a good retort to that as he stays silent for a long moment

before frowning.

“What Alpha doesn’t want kids of their own?”

“/Yours/,” Chuuya snaps, rolling his hips again for emphasis. Dazai bites his lip, holding back the sound trying to escape. “You’re my /home/, Osamu.”

Dazai’s gaze locks with Chuuya’s again, and he looks so innocently surprised.

It’s not like Chuuya doesn’t /try/ to make that clear every day, but sometimes the best approach is the direct one. “I don’t want to come home to anyone else. I don’t want to spend my rut with anyone

else. I just want /you/. Exactly the way you are.”

Dazai closes his eyes, grabbing the back of Chuuya’s head and pulling him down to bury his nose in the Alpha’s neck.

“Chuuya doesn’t play fair.”

“Neither do you.”

“Go back to begging to fuck me, I liked that better.”

Chuuya scoffs.

“Shut up.”

Dazai doesn’t respond, sighing and breathing in Chuuya’s soothing, spicy scent, building stronger as his body slowly heats up again.

Chuuya starts panting as his hips roll and the knot goes down, free to slowly fuck Dazai again. Dazai smiles,

lifting his legs to wrap tight around Chuuya’s waist, rolling his hips to meet Chuuya’s languid thrusts.

“Good boy,” he sighs. Chuuya just grunts in response, hips starting to speed up before Dazai clicks his tongue, reaching between them and gripping Chuuya’s throat, applying

pressure until Chuuya stops. He whines, looking down at Dazai with his pupils blown wide and hungry.

Chuuya gasps when Dazai squeezes, body shuddering. “Don’t rush now, sweetheart.”

“Mm, /‘Samu/,” Chuuya breathes. Dazai nods, looking entirely unaffected and making Chuuya’s

hands grapple for purchase on the Omega’s shoulders.

“What is it, baby?”

Chuuya’s hands flex and squeeze Dazai’s shoulders, the only thing leaving his mouth are little gasps. Dazai squeezes until Chuuya’s eyes flutter shut before releasing most of the pressure.

“I can’t help you if you don’t tell me what you /want/, Chuuya.”

“Said I could fuck you all night,” Chuuya croaks. He leans forward into Dazai’s palm. “You /promised/.

Dazai coos at him, pulling him in to capture his lips in a slow, deep kiss. Dazai’s hand slips from Chuuya’s

throat to the side of his neck as he gently encourages him to move his hips again.

“You /can/, baby, but take your /time/,” Dazai whispers against his lips. “We have all night, make it /good/.”

Chuuya kisses him again, nodding.

“I’ll make it good.”

“That’s my good boy,” Dazai says sweetly, meeting Chuuya’s hips with each slow, deep thrust. Chuuya lasts a while like that, but the buzzing /need/ is becoming unbearable and it’s not /enough/.

He snaps his hips a little harder, biting at Dazai’s lips as he does. Dazai laughs

softly, shaking his head.

Chuuya kisses him to quiet him, trying to take the reins, trying to speed up his pace but a low, rumbling voice makes him freeze, shivering. “What did I say, sweetheart?”

“/Please/.”

“What did I say?”

Chuuya groans, dropping his face to Dazai’s

shoulder.

“Take my time,” he says miserably.

“/Good/.” Dazai’s gentle fingers in his hair make Chuuya want to do /exactly/ what he says, but it’s /hard/. He needs that release. His stomach is tight, coiled up and ready to snap. “Why are you /rushing/, then?”

“I /need/--!”

Chuuya moans when Dazai rolls his hips, slow and /agonizing/.

“Tell me what you /need/, Chuuya. I’m listening.”

“/Fuck/, Osamu.”

“You’re already fucking me, baby, what /else/ do you need?”

Chuuya bites down on Dazai’s shoulder because he needs /friction/, but Dazai hasn’t

said he can keep going yet and he’s losing his mind. It’s so good and not enough at the same time.

“Need to knot you,” Chuuya mumbles. Dazai tilts his head like he’s thinking it over and Chuuya holds in a frustrated growl when he rolls his hips again.

“Mm, not yet,” he says.

Chuuya wheezes out a little groan.

“Please.”

“I said /no/, baby.”

Chuuya’s hips jerk against his will and he moans. He /tries/ to stay still but he just /can’t/. He feels frustrated tears sting his eyes as he bites down on Dazai’s shoulder again.

“I-I /can’t/. Please, Osamu.”

“You /can’t/?” Dazai rumbles. Chuuya blinks quickly, shaking his head slightly even as Dazai’s hands cup his jaw and push him back to look into his eyes. “You /know/ what to say to make it stop, sweetheart. And you /know/ how upset I’ll be if you /lie/.”

Chuuya purses his lips, shaking his head again, looking Dazai right in the eye. He leans into Dazai’s hand, not speaking and nuzzling into his hold.

Dazai’s eyes dart over him again before he shrugs, one hand slipping around Chuuya’s throat once more. The Alpha gasps, body

thrumming with exhilaration. “You can knot me when I /say/ so.”

“Okay,” he breathes. “I’ll be good.”

“Then /fuck me/ slowly."

Chuuya nods, taking it slowly, breathing in Dazai’s scent as he goes. The little, appreciative noises Dazai makes make his body buzz with excitement.

He’s doing it right. He’s making Dazai feel /good/.

Still, the ease of his breath, the clear mischief in his eyes makes Chuuya’s mind race.

He promised to fuck him until he couldn’t remember his name and right now Dazai is /very clear-headed/. He needs to work harder.

With his mind set on /one goal/, Chuuya rolls his hips, angling them up, grinding into Dazai and drawing a moan from his lips as his eyes slip closed.

The rush of pleasure from making Dazai look like /that/ is scorching as it consumes him, his mind growing foggier.

He just wants /more/.

“‘Samu,” he slurs, hips driving in hard and slow and agonizing as they hit Dazai /right there/ ceaselessly. “Love you, ‘Samu.”

“I love you, too, baby,” Dazai gasps, nails digging into Chuuya’s back as his ankles dig in, too. Chuuya leans in, nose brushing

over Dazai’s jaw, pressing open-mouthed kisses against flushed, bruised skin.

“My Omega. So beautiful,” he whispers reverently, feeling Dazai shuddering beneath him and preening.

Dazai’s head is starting to spin a little, the pleasure building up in his gut,

drawn tight like a bow string ready to /snap/.

“Just like that,” he whispers, mouth hanging open as Chuuya grinds his hips at just the right angle. “/Chuuya/!” Everything goes white as Dazai tenses, shaking through his orgasm. Chuuya’s hips slow to a stop, but Dazai’s heels

dig deep into Chuuya’s back. “Don’t stop, keep going.”

“But you’re--”

“/Keep going/.”

Chuuya shuts his mouth, picking up where he left off and grinding slow and rough into Dazai’s body. The overstimulation sends shocks over Dazai’s skin, jolting him, but Dazai relishes the

feeling. He holds tight to Chuuya’s choker, pulling him in for a kiss. He moans into the embrace when Chuuya rolls his hips.

Chuuya bites Dazai’s lip lightly, tugging it.

“Gonna make you come until you can’t anymore,” Chuuya growls. Dazai chuckles.

“Alright,” Dazai agrees,

actually breathless. “Taking such good care of me.”

Chuuya nods. He /is/. Because he’s good and he listens and he’s obedient. Dazai moans again as Chuuya goes even slower, dragging his cock in and out of Dazai with precision and determination. If he makes Dazai come apart, he’ll

be allowed to knot him.

If he keeps his promise to make Dazai forget his name, Dazai will tell him what a good boy he is and let him fuck him /harder/ and /faster/. But first, he needs to take Dazai apart. He nips at one of Dazai’s nipples, and sucks it, slowly flicking his

tongue over the little bud in time with his thrusts.

He grinds his hips and shifts Dazai to get a better angle. As soon as Dazai’s legs get thrown over Chuuya’s shoulders, he knows Chuuya will keep his promise. When he cums again, he whines out Chuuya’s name, still chasing

that fullness, that slow, sensual roll of Chuuya’s hips. “Do it again, baby,” he demands. Chuuya’s heart skips. Dazai likes it!

He eagerly sucks Dazai’s nipple before moving to the other side. His grip on Dazai’a thighs is bruising and Dazai wants him to hold /tighter/.

He wants to be marked up and claimed by his Alpha, to leave his rut absolutely wrecked. He doesn’t even want to be able to talk afterward.

And when Chuuya has /explicit/ instructions, he /performs/. “Good boy,” he gasps. He’s dizzy with pleasure and overstimulation, chasing the

stinging sense of /too much/ and /not enough/ that roar within him.

“Love it when you come on just my cock, ‘Samu.”

“Yeah?” Dazai breathes. He looks so gorgeous spread out on the bed, his hair messy and disheveled. Chuuya nods, as he fucks him the way he wants.

He’s slow and rough and eager. “Give me /more/, Chuuya.”

“Tell me how,” Chuuya says immediately. He wants to give him /everything/. He wants to give Dazai every inch of himself. He wants Dazai to own him and claim him. He wants /everyone/ to know that he /belongs/ to someone.

“I don’t wanna be able to walk tomorrow. Fuck me like /that/.”

Chuuya nods, growling and snapping his hips harder, feeling the crash of his hips against Dazai’s. Dazai cries out, smiling in /bliss/.

Chuuya keeps his pace as slow as possible while he drives his cock as hard

and as deep as he can. The angle is perfect and Dazai’s eyes roll back in his head, his toes curling and his nails scrape down Chuuya’s back. “Chuuya! /Yeah/! Just like that, baby.”

The praise makes him so warm and /confident/. He feels like he could do /anything/ as long as

Dazai keeps saying his name like that. “More! Chuuya, /harder/.”

Chuuya reaches up to hold Dazai’s shoulders down as his legs wrap around Chuuya’s neck. Chuuya keeps him still as he fucks into him as hard as he can.

The bed rattles and slams against the wall and Dazai is so

/hot/. His body clenches around Chuuya every time he cums and Chuuya’s losing the last strings of his restraint.
Dazai’s body is pliant and open underneath him.

He whispers praise like Chuuya is the best thing in the world, like Chuuya is doing /exactly/ what he wants.

Chuuya turns his head to bite Dazai’s calf, whining when Dazai clenches around him again.

He’s panting now, wildly out of breath and flushed. His blush runs down from his ears to his chest and Chuuya drags his hands down the soft skin.

“So fucking /beautfiul/.”

Dazai’s eyes are heavy-lidded as Chuuya’s hips still move as deep as he can. His body is boiling hot and all he wants is to knot his Omega, to tie them together and claim him.

Dazai watches Chuuya struggling above him, lost in hazy pleasure. He registers that he’s /close/ again

and he’s grateful for the way his pre-heat lets him /do this/ because Chuuya is /tireless/. He’s overwhelmed and this orgasm rocks him to his core.

He can barely think and it’s /wonderful/. His mind is quiet and pliant and it takes him a moment to register Chuuya leaning over

him, hips jerking desperately and Dazai’s legs around his waist again. His face is pressed into Dazai’s throat and he rumbles out a string of desperate begging.

“‘Samu, please, please,” he whispers. “Can I knot you? Please, Osamu? I wanna--I wanna cum /so bad/.

Wanna knot you, wanna /claim/ you. Mine, /mine/, please.” Dazai pushes Chuuya back with a shaky hand on his chest. Chuuya’s eyes are completely fogged over. He’s consumed by the rut completely now and he looks close to tears.

Dazai smiles, strung out and feeling the distant need for that knot /inside him now/ tickling his subconscious.

“Yeah,” he whispers. “Yeah, sweetheart. Knot me.”

Chuuya makes this elated noise and pulls out. He grabs Dazai’s lax body and flips him over, positioning Dazai with

his knees under him, his ass up and his face pressed into a pillow. A hand on the back of his neck keeps him still. And Chuuya is so /eager/ and /happy/ with his work that Dazai just rolls his eyes.

“Can I do it like this? Please? Can I, Osamu?”

“Yes, baby,” he whispers.

Chuuya nods and pushes in slowly. He drapes his body over Dazai’s back and then his hips start up a frantic, desperate rhythm. His hips slam into Dazai’s and every thrust rocks Dazai’s body forward. Dazai arches back into it with a sigh as Chuuya fucks him like he was

/born for it/.

Dazai is content like that, but then Chuuya’s arm snakes around his waist and drags Dazai’s hips /back/.

And each snap of his hips is already brutal, but the way he drags Dazai’s hips back to meet it leaves Dazai feeling /used/ and /needed/ and /wanted/ and he

lets out these little encouraging sounds, feeling the way Chuuya fucks him even faster, like he has /one/ concern, /one/ need.

“Perfect Omega, so pretty when I fuck you.”

“Tell me how pretty I look,” Dazay gasps. “How good do I feel, sweetheart?”

“So pretty, Osamu,” Chuuya

murmurs out while he sucks bruises into Dazai’s shoulder blades. “Spread out and tight and /perfect/. Gorgeous,” he whines.

“How good do I feel, baby? How much do you like to fuck me?”

“Feel like you were made to take my cock,” Chuuya growls. “Love fucking you, ‘Samu.

Love the way you feel around me, wanna fuck you every day. Wanna fuck you for hours and kiss every inch of your body. Wanna /worship/ you.”

That sounds /nice/. But the way Chuuya’s fucking him, he tears another orgasm out of Dazai that he /wasn’t expecting/ and suddenly he’s

/speechless/. All he can think about is the feeling of Chuuya’s cock stretching him out, filling him up. All he wants is more. He wants Chuuya’s knot like he needs air.

“/More/!” he demands. It’s all he even /can/ say.

Nothing else matters, nothing else /exists/ but this moment, this feeling. He knows he’s moaning and babbling /filth/ and with how Chuuya’s rhythm starts to get erratic, he’s /close/. “/Harder/!”

Chuuya does, his hold around Dazai so tight he’s /definitely/ going to bruise and

that thought alone has him ready to cum /again/ and he can’t even /fathom/ it. Their hips slam together and his cock goes so /deep/.

Dazai’s head is spinning. It’s perfect. “Knot me,” he croaks, reaching back to grab Chuuya’s hair and pull /hard/. “Knot me /right now/.”

Chuuya /shudders/. Dazai’s body tightens one last time, head thrown back as he /screams/.

“/Osamu/!” Chuuya growls, knot swelling and locking them together. His hips roll as the knot settles and ties them together and Dazai pants beneath him, preening and sated.

“Good boy, you’re /such/ a good boy, Chuuya,” he slurs out as Chuuya collapses on top of him. He just grunts in acknowledgement.

The cool down is longer than the first time, but eventually, Chuuya sits up, carefully maneuvering them to a new position, still locked together.

He leans back against the headboard with Dazai settled securely in his lap. He wraps his arms around Dazai’s stomach, his forehead resting on the Omega’s shoulder.

“‘re you okay?” he asks softly. Dazai sighs, leaning back to kiss the side of Chuuya’s head.

“I’m perfect. How are you, baby?”

“M’good,” he whispers. “Love you.”

“I love you, too, Chuuya.”

They’re quiet for a moment as Dazai catches his breath, enjoying the feeling of being /full/ and sitting against his mate.

“Chibi wasn’t lying when he let me keep going, right?”

he asks, tired and close to falling asleep, but needing the confirmation. Chuuya shakes his head quickly, kissing Dazai’s shoulder.

“No, I was okay. Promise.”

Dazai nods, purring as his eyes droop.

“Good. I don’t want to push you too far. S’not a competition.”

“I’m /fine/,” he grumbles, holding Dazai tighter.

Dazai hums, turning his head to run his nose over Chuuya’s temple affectionately.

They sit in languid silence, locked together and Dazai is certain they’ll get a few hours of sleep before Chuuya’s rut wakes them again.

Still, he grins and can’t stop himself from whispering.

“So, you wanna adopt a baby?”

“/Eventually/,” Chuuya clarifies. Dazai shrugs.

“Whatever you say, but we’re not getting any /younger/.”

“We’re /twenty-four/.”

“My biological clock is ticking,” Dazai counters and

Chuuya huffs with an exaggerated eye roll.

“Shut /up/,” Chuuya growls, biting down on Dazai’s mating mark in warning. “Your pillow-talk /sucks/.”

“Then stop /talking to me/.”

Chuuya lets out a quiet, defeated sigh. “Osamu?”

“Yes, baby?”

“Go the fuck to /sleep/,” he grumbles. “You need the rest.”

Dazai whines, dramatic flair in everything he does, no matter how /annoying/.

“/Fine/, but if I can walk when we wake up, I’ll be relentless until Chibi can get the job done right.”

Chuuya huffs.

“I don’t plan on giving you the chance to test it,” he grumbles. “I’m gonna fuck you all morning, clean you, feed you, and fuck you /again/, until we pass out.”

“Oh?” Dazai muses. “I don’t remember telling Chuuya he could fuck me in the /morning/.”

“/Please/?” Chuuya whispers,

sounding so sincere and needy. “I wanna make you feel /good/. I wanna keep you in this bed until your heat is over.”

“Mm, that so?”

“I need it, /please/?”

Dazai hums, rolling his hips a little, eliciting a little moan from them both.

“I /suppose/ I can let Chuuya fuck me in the morning, until I’m hungry.”

Chuuya nuzzles just behind his ear, kissing him softly. “But after you clean me and feed me you're gonna have to /work/ for the right to knot me again.”

“Okay,” Chuuya whispers with an eager nod.

“And if the Chibi /really/ wants to pamper me and keep me in bed for my /whole/ heat, well...how could I deny such an /earnest request/ from my baby?”

Chuuya licks a stripe over the side of Dazai’s neck.

“Thank you, Osamu,” he breathes. “I’ll take such good care of you.

I promise. I’ll make you feel good.”

“I know you will, sweetheart. You always do.”

Chuuya hums, letting his eyes droop closed as Dazai drifts off in his arms, completely spent. Despite what he says and how he acts, he’s eagerly waiting for his heat to hit.

He snuggles a little more heavily against Chuuya’s chest, allowing his mind to rest in the warm embrace of his mate.

For now, he’s exactly where he needs to be.
