Chuuya really can be silly sometimes, Dazai thinks as he watches over the sleeping redhead.
Insisting to Mori that they needed separate beds for this mission— Dazai is certain they did not. But if the alpha had argued instead of agreeing, Chuuya would have bitten his head off. Not really his ideal way to go. So, reluctantly, he rolled his eyes and said that he would rather be tortured than sleep in the same bed as an alpha who smelt like a wet dog.
And he didn’t lie! He would rather be tortured— but Chuuya doesn’t smell like a wet dog, he smells like oranges and sweet candied apples, enough sugar to make his teeth rot just from scenting him.
No, Dazai would not share a space with a wet dog, but he would very much like to crawl under the sheets, plaster his chest to Chuuya’s back and mouth at his scent glands until his scent is imprinted inside the redhead’s skin, and the taste of oranges forever coats his tongue.
Chuuya smells way too good to be an alpha anyway. If Dazai hadn’t seen him go into rut before he might not even believe it himself.
But that doesn’t matter now; Dazai’s going to change that soon enough anyway.
For now, the other alpha sleeps— in his separate bed — with only a thin blanket to cover him, because he claimed he was ‘too warm’.
Poor baby.
With their mission over, the only thing left to do in the morning is call Mori. Let the boss know that everything went according to plan and that Dazai now has his own business to take care of.
And Dazai can do that without Chuuya being conscious.
Asleep like this, Chuuya looks so pretty. Fiery red hair fanned out on the pillow behind and beneath him, curled up in a little ball under the sheet. The soft scent of sleep and comfort rolling off him grows stronger and more relaxing the closer Dazai gets. He's sure that if he wasn't wired on coffee and lust and hormones, he could fall asleep almost instantly, with his nose pressed to Chuuya's throat. He's more sure now than ever before that this is the best course of action. This is the right thing to do. For them.
Sitting on the edge of the bed, Dazai reaches his hand out. Letting his fingers find unruly red curls and brush through them. Chuuya’s hair is so soft , if a little messy, and he sighs gently into the touch. Not awake enough to process it as Dazai’s touch.
The alpha purrs under his hand— what kind of alpha purrs ?— and Dazai’s heart skips a beat.
It’s adorable. Trust Chuuya to show his true colours when he's fast asleep.
He almost feels bad about having to wake the little alpha up. But at least he’s going to do it nicely. At least he isn’t going to hurt him.
Dazai slips off the bed quickly, stripping and throwing his clothes over the spare bed. That’s all it’s good for anyway. He leaves his bandages on though, less for his own comfort and more because, well, he's nearing rut himself, he doesn’t know what kind of reaction full-body skin contact will create.
He might go into rut there and then— maybe even try and take Chuuya without any prep— and that wouldn't be good for either of them. Dazai has a list to follow, things he needs to do to increase the chances that this works. He has to keep his composure.
Mori was more than happy to provide Dazai with said list— the criteria for ‘bitching’ he had called it. He probably knew what Dazai wanted it for too, he just doesn’t care. As long as Double Black works well together, he doesn’t care why.
If he’s going to help Chuuya become what he was supposed to be— Dazai’s omega — then he needs to take it carefully and slowly. He needs to take his time and make sure everything is perfect. So that his little firecracker doesn’t need to worry about a single thing.
Lifting the sheets, Dazai crawls under, feeling himself grow hard in excitement from just proximity. For now, Chuuya’s scent stays subtle. Still sweet, still sugary, but not as strong as it’s tasted before. It doesn’t stick to Dazai’s tongue or throat yet, not like how he wants it to.
Pressing his bandaged chest to Chuuya’s back, Dazai briefly mourns the lack of contact between them, before he noses against the alpha’s neck. Breathing his scent in with a shuddering sigh, followed by another, deeper inhale, trying to savour the sweetness.
The alpha’s nose presses against the scent glands, tongue peaking out to lap over the skin desperately. The remnants of sweat salt and blood still linger, even long after his post-mission shower.
Chuuya makes a noise, low in the back of his throat, confused in the haze of sleep (he must not have been in as deep a sleep as he thought). Dazai shushes him, licking his scent gland again as one of his hands wanders under the blanket. Slipping under the waistband of his underwear to wrap his fingers around his cock.
He gasps at the contact, pressing impossibly closer to Chuuya as he stifles a moan against the redhead’s neck. Grip tightening around himself, frantically jerking himself off as he breathes in the sweet citrus scent beneath his nose.
“’Zai?” the redhead mumbles sleepily. Precum beads at the head of Dazai’s cock, and he shivers as he spreads it down the shaft. Roughly tugging at his erection as he angles his hips away from Chuuya’s back. He isn’t awake yet, not properly at least. And Dazai wants to keep it that way. If the little alpha wakes up too early Dazai will have no chance. As much as he doesn’t like to admit it, Chuuya is much stronger than him. If he really didn’t want Dazai on him, he’d have no problem kicking the alpha off.
But he needs to do this tonight. He’s never going to have an opportunity as perfect as this again.
Shakily he shushes Chuuya, pressing his lips to the nape of his neck as his cock twitches in his palm. Fresh orange fills his nose and throat as the redhead slowly, very slowly, relaxes back into the mattress, drifting back off into the realm of sleep.
Dazai was already on edge, but the first gentle hint of caramelised sugar, a scent that tastes so sweetly of arousal, sends him over. His orgasm— his first of many tonight he’s sure— ripping through him with a loud, shuddering gasp. Almost on instinct his lips part, fang aching, prepared to bite down around flesh and claim Chuuya as his , finally . Somehow he manages not to, sinking his fangs into his lower lip instead. It’d wake Chuuya up instantly, to be bitten now, and Dazai has no guarantee that it’d even take.
The redhead’s scent grows sharper as he awakens again, shifting almost out of Dazai’s grasp as he stretches.
“Dazai…?” he murmurs again. Snapping Dazai out of his post orgasms haze. His fist is still in his underwear, cum covering his fingers. It’s a little awkward to lift his hand without stirring Chuuya even more, but he manages, wiping the sticky liquid over the redhead’s scent glands, possessively.
Chuuya makes a confused noise, trying to turn his neck to look over his shoulder, still half asleep. Dazai stops him, pressing his clean hand against the alpha’s cheek to push him back into the pillow. Revelling in his scent mixing with the redheads as his thumb rubs the sticky release into his skin.
Just the sight is enough to have him growing hard again.
The redhead whines at the feeling, melting into Dazai’s touch like butter, exactly how he thought he would. He’s so soft when he’s sleepy. So sweet and lovely and gentle.
Dazai takes full advantage of it. Kneading his fingers into the other alpha’s scent glands until he smells like sleep and hazy pleasure again. Until he stops trying to roll over and instead lets himself relax into Dazai’s more-than-capable hands.
And Dazai… fuck, Dazai is horny . The sight of Chuuya so calm, so relaxed with him is heavenly. He’s rock hard again in no time, cock red and dripping precum onto the sheets between them, his knot still semi-formed at the base.
He commends himself on his self-control as he wraps a hand around himself again, immediately jerking off in quick, rough strokes. His fist tightening around the knot with each twist upwards until his vision blurs and he sees stars. Cum dribbling over his fist, threatening to join the sticky mess on the sheets.
Before that can happen, Dazai spreads the thick liquid over his fingers. He hates the feeling of cum, it’s uncomfortable when it’s sticky, and even worse when it’s dry, but Dazai is willing to put up with it if it means he gets Chuuya like this more often.
With a gentle nudge, he forces the other alpha to roll over, until Chuuya is half laying on his stomach. One leg bent up to provide Dazai with all the access he needs.
He slots himself behind his redhead. The alpha's clean hand finds Chuuya’s ass. Groping him indulgently for a few minutes— and mourning that he doesn’t have more time to appreciate the work Chuuya puts into his body— before he pushes at the flesh, the fingers of his other hand tracing over the alphas rim with feather-light pressure.
He has to be gentle. He has to be slow . Chuuya’s already half-woken up, Dazai doesn’t need him to wake up fully, not now. Not when he's so close.
With that thought firmly in mind, he presses the tip of his finger inside. Slowly stretching the alpha, using his cum as lube. Dazai thinks it’s probably the hottest thing he’s ever seen. And it takes everything inside him not to plunge his fingers in up to the knuckle and stretch him quickly. Chuuya probably wouldn’t appreciate that.
So he starts easy. Gently getting him used to the stretch as he sleeps peacefully on. Gradually adding another finger when he feels relaxed enough around the first.
He doesn’t know how Chuuya is still asleep. It’s a miracle really.
It takes a lot of work and a lot of patience. But, eventually , Chuuya feels stretched enough.
Precum dribbles down the side of his cock, and Dazai uses it to slick himself up as he lines himself up with Chuuya’s entrance. It takes an unholy amount of self-restraint to not sink to the base immediately, to slowly, and carefully, line himself up and push inside. The alpha’s hands shake where they rest on Chuuya’s hips as he gradually inches in.
He’s so tight and so hot , and Dazai is so, so lucky to have met Chuuya. The sight of his cock disappearing past the tight ring of muscle is addicting , and the scent of sex grows heavier and heavier until it’s all Dazai can smell as heat surrounds him.
It’s incredible . Dazai can barely think beyond the pressure and slick warmth around him as his hips unconsciously buck.
Chuuya whimpers in his sleep, fingers twitching around the bed sheets as Dazai noses at his scent glands again. Tongue lapping over the skin indulgently, picking up the taste of orange and cum, until the skin is soaking and he’s sure the glands will be sore by the morning.
The alpha pistons his hips steadily as his knot grows. His teeth find the junction of Chuuya’s throat, chewing almost reverently as his fangs begin to ache, and the urge to bite, to sink his teeth in until Chuuya is irreversibly his grows stronger and stronger. Just the thought makes his blood boil and a moan reverberates out from his throat.
“ ‘Zai? Wha’s— ” Chuuya’s sleepy rambles are cut off as his breath hitches. The head of Dazai’s cock glancing off his prostate with each rock forwards.
“Shhh,” he tries to whisper, but it comes out as more of a hiss with his teeth still firmly locked around the other alpha’s shoulders. His tongue continues to flick at the scent gland while he gently takes Chuuya’s skin between his teeth, chewing to fight the urge to bite.
“What…?” he murmurs. Trying to turn his head to see behind him. Even in the haze of sleep, Chuuya is too cautious of Dazai.
Unlocking his jaw, Dazai pulls away ever so slightly. “ Shh , Chibi. It’s okay ,” he whispers again. His hips never slow in their thrusts, even as Chuuya begins to wake.
Chuuya shakes his head, confusion filling his scent alongside the quickly building taste of lust. Sweet lemon and honey and orange melt together into a delicious mix of scents. Each taste leaving Dazai dizzy and breathless. “Dazai? Wha’re you… doing?” he slurs. “ St— stop it .”
“ No, no, ” he pleads, desperately willing Chuuya to go back to sleep, to let him get on with it. “It’s okay, Chuuya. Silly dog. It’s okay, this is good .” Dazai knows he sounds as desperate as he feels. Any other day Chuuya might make fun of him for begging, but he doesn’t care about that right now. “ It’s okay, ” he breathes out as his hips stutter. Knot forming with each push and pull, catching on the alpha’s rim with painful pressure. " s’okay .” He’ll repeat it as many times as he needs to if it’ll keep Chuuya in his arms, and on his cock.
He feels heavenly , and every time he clenches around Dazai it brings him so much closer to coming. His knot swelling impossibly large until it feels like it might never go down again.
“ Fuck !” Chuuya chokes as Dazai’s knot tugs at his rim. He still smells like sleep, but the alpha doubts he’s going to be able to fall asleep again tonight. Neither of them is going to be getting much sleep actually. Not if Dazai has any say in it.
With one last harsh thrust forward, burying himself as deep as possible, Dazai sinks his fangs into Chuuya’s scent gland. Unable to stop the overly high-pitched moan that the taste of blood and Chuuya forces out from him. Knot swelling for a final time as he comes, locking himself inside the other alpha.
“Dazai what the fuck ?” Chuuya mumbles, voice swaying between anger, pain, confusion and lust as pain bursts across his neck.
But all Dazai feels and knows is bliss .
Pure bliss.
His fangs are buried inside the sweetest smelling omega ever( well , maybe not an omega yet , but he will be), and his knot is sheathed inside the hottest, tightest ass he’s ever felt. He can’t really think beyond that.
Dazai has no idea how long it takes for his knot to go down. Usually, it doesn’t take too long— but this is Chuuya . He knew this would be different.
His jaw aches when it finally unlocks from Chuuya’s scent gland. And he can’t help himself from brushing his tongue over the bite mark. Feeling his mate ( his mate! ) jolt around him with a low whine. But by then his knot has gone down enough to pull out. So he can clean them both up and move on to the next stage.
“ ...Why? ” Chuuya whimpers, as Dazai washes over his neck with a wet cloth. He looks up at the alpha with watery blue eyes, and for a moment Dazai feels guilty. But Chuuya’s unconscious before Dazai can even think about answering him.
That's for the best really. He can come up with something to tell him tomorrow. When his hormones have begun to rage with the mating mark Dazai has left on him.
One day he will thank Dazai. He knows it. Chuuya will thank him for making him Dazai’s omega. Just maybe not today… or tomorrow.
