Chuuya feels hot under the collar in an unpleasant way. He's not sure how, but he's certain it's Dazai's fault. All inconveniences in Chuuya's life lead to Dazai one way or another since the moment they met, that's just the principle under which he operates.
He's on his way to the Bosses' office, the copy of redacted proposal that mayor just pitched to his administration in one hand, the phone in the other.
to: Mackerel
Where the fuck r u?
He hears tell-tale ding of a text being delivered barely five steps ahead of himself, coming from the dark nook to the side, perfect place for an ambush. Or for the creeps like Dazai to hide in order to spook subordinates shitless.
"Aren't you bored, lurking around like that?" Chuuya asks with a hint of annoyance when turning to face smug bastard.
"Chuuya~ you wound me!" Dazai makes a little theatrical play of stubbing himself in the chest and almost-fainting. "I'm never bored if I can bother you."
"Tsk, idiot," Chuuya swats at the palm that tries to latch onto his waist like an annoying octopus tentacle. "Keep your mitts to yourself."
"I can't, Chuuya looks so squishy." Dazai makes grabby-hands motions.
"I'll squish your brains out," he mumbles in response to which Dazai just smiles and falls into the step with him, releasing a bit of his scent. "That reminds me, we should stock up my heat nest."
Dazai gulps loudly beside him. "Don't we already have everything at home? Also, ouch, way to doubt me! Chances are my Chibi is full of even smaller chibis already~" He tries to redirect the conversation but Chuuya wasn't born yesterday. He speaks fluent bullshit-Dazai.
"a. I'm not normally spending my heats at home, so even if we end up doing it there this time around, I'd still like to prepare my usual place in case Boss has some commission for you and I have to ride it off alone." Chuuya hears low rumbling being born in Dazai's chest at the possibility, but pays it no mind. "b. It's amazing how your genius brain is a complete blank sheet in anything that concerns me. I can't get pregnant outside of my heat, and for it we'll take shots to avoid unplanned surprises."
Dazai's scent actively sours at that.
"But…"
"I'm not done," Chuuya doesn't allow him to intervene. "And c. Don't think I didn't notice your tells, so. What's this about? Spill."
Dazai giggles nervously.
"Nothing, slug, just wanting to be a good alpha for you."
"As if," Chuuya scoffs, "Let it out. I don't have all day." He impatiently taps with his foot when they arrive to the elevator doors and Dazai presses the button for him.
"Okay well, you're a fool if you think there's anything Mori can do to pull me out from you in heat, pun intended." Dazai squares his shoulders at that, fully believing the statement. "You also couldn't be more farther from the truth — I think of you constantly, I note everything about you."
"Creep," Chuuya mumbles, cheeks heating with a blush. The elevator dings when opening the doors and he steps inside, pressing the button for the top floor.
"Not the point," Dazai dismisses the remark, staring at him from the hall, "The point is — I know you, I definitely got you pregnant." His next comment is timed perfectly with the doors closing. "I also, kinda, somewhat, ravished your heat nest when presenting and completely forgot to clear the scene. We should burn that place down now."
"DAZAI!!" in angry and loud scream bounces off of the metallic cage of the elevator as it goes up.
He makes Dazai check the damage on his heat nest in Suribachi City with him. He has to practically drag the bastard with his ear, like a fussy toddler, berating him for not swiping the crime scene clean while Chuuya was in the meeting with the Boss.
Dazai throws a whinny fit, but it's a half-assed one, barely three-out-of-ten on a scale of his personal annoyance-meter, so Chuuya can ignore it without inducing the headache.
"Tell me now, how bad is it?" Chuuya asks, slotting the keys into the lock on the heavy metalic door to the apartment.
Dazai grimaces. "I'm serious about burning it down," he says sullenly, and then adds, "Give me five minutes to find gasoline and a lighter."
Chuuya throws him sceptical look over the shoulder.
"I can make it three if you give me the lighter, I'm ready to sacrifice a little handsy for a good cause."
"Sacrifice yourself, genius. Should've thought about it before," he exhales and turns the handle, shoving the door inside.
The place stinks. Chuuya makes a beeline for the toilet to throw up, while Dazai opens the windows to air out the stale stench.
"Definitely pregnant," Dazai smugly teases him, leaning onto the door frame, letting out his soothing scent to try and ease Chuuya's symptoms.
Chuuya throws the bucket from under the sink at him.
"Get to fucking work, jerk," before heaving above the toilet bowl again.
His heat is late by approximately a week, when he decides to bite the bullet and do one of the at-home pregnancy tests. Best would be clear it out with the Boss, but Chuuya is not ready to admit to him that his protégé got him pregnant. For a brief moment he even considers Agency doctor, but he has no means of getting a hold of her new location and asking Dazai is out of the question.
"I'm surprised you don't have them at home," Dazai comments and Chuuya jumps on his spot, dropping the instruction onto the floor in surprise.
"Yeah, well, I don't have a habit of sharing a cycle with nutthead alphas, and I can't get pregnant outside of the heat, so there was no need." He ignores how pleasant Dazai smells at his admission of not letting other alphas into his heat nest. Or his nest in general, but the bastard doesn't deserve that information. "This is just a precaution."
"It's gonna come back positive, I promise," Dazai folds himself over Chuuya, burying his nose at his mating gland, still bare from the reciprocal bite. "I can smell it."
Chuuya nudges him with the elbow.
"You got your instincts like what, three month ago, and want to tell me you can smell that shit on me?" he scoff in doubt, before shrugging his shoulders in a silent ask to be let go. Dazai's hands fall from him reluctantly, stroking his lower stomach at last.
"I'm a genius, don't forget that," Dazai huffs in annoyance when Chuuya shows him to turn around for some privacy.
The act of peeing in a cup and sticking a pregnancy test inside is very humbling. Dazai, sing-singing and tapping on the door frame with his fingers doesn't bring additional comfort.
Chuuya washes his hands in the sink, before sitting on the lip of the bathtub and counting in his head. Maybe he should've brought his phone or watch with him to track time.
"Chuuya worries too much," Dazai tries to reassure him warmly and falls to his knees in front of him.
"You're not worried enough," he counters and pulls on Dazai's hair, laying his head down onto his lap and scratching the nape. The scar from the mating bite there is still slightly red. It will stay like that — tangy with scab, never truly healing to the end until Chuuya allows to bite him back. "Count your days if you're right," he threatens with hesitation.
"My days are numbered anyway," Dazai murmurs into his stomach before laying a gentle kiss through the shirt to his navel and looking up. "Time."
Chuuya holds his breath when reaching for the cup.
It's positive.
"Told ya," Dazai says before standing up and giving Chuuya his hand to help. Chuuya ignores it in favour of intense staring contest with two red lines. "We've got that," Dazai assures him, "We're Double Black."
Chuuya signs heavily at that.
"Boss is gonna be over the fucking moon," he says sarcastically and Dazai chuckles in response.
"I'll take care of him," he promises. "I'll take care of everything my little omega desires."
Chuuya leans onto him, his head to Dazai's stomach, almost the mirror of how they were before. The test is still in his hands, an undeniable proof of Dazai always being right.
"I'm not dealing with it longer that it has to be," Chuuya settles his mind. "If this baby is late on his due date even for an hour, you're fucking me into labour or the city won't see another day."
"As you say, partner," Dazai readily agrees.
