Little known fact; these two have definitely fucked before. Well; technically, their first time together was a few months ago when Dazai turned 18. They, however, have been sneaking around and doing corny little relationship things in secret though. Like kissing, holding hands, cuddling, making food for each other, and what not.

Work Text:

Dazai walked the halls of the port mafia.

 

It was cold, and made the little skin he had showing stiffen and shiver. Dazai had just gotten back from 'training' his mentee, Akutagawa. Who was, frankly, very clearly holding back from what he could really do.

 

Dazai remembered how Akutagawa looked up at him, with hatred in his eyes. But he knew better. Dazai knew Akutagawa needed him. Why else would he keep coming back for more training, allowing Dazai to both verbally, mentally, and physically abuse him?

 

Anyways, back to the topic at hand. He was supposed to be meeting with Mori. That memory caught a sigh from Dazai's lips. How he fucking hated Mori. He had to not only deal with Akutagawa and Mori in one day — this was definitely punishment for his crimes.

 

Dazai didn't bother to knock. He hasn't ever, really. Mori was smart enough to know when Dazai would be here, and it was highly unlikely he had something in here he didn't want Dazai to see. If it was something that could emotionally fuck with the eighteen year old.. then Mori would definitely let him see anything.

"Mori. I'm here."

 


 

 

Kouyou walked over steadily to the short chabudai, placing the tray of tea and snacks down as she herself sat down after.

 

The pink haired woman opened her mouth to speak first. "Lad," she hummed out.

"You've been spending quite some time with the demon prodigy."

 

Chuuya raised a eyebrow momentarily, before straightening up just as quickly. "Of course I am. We're partners, I have to." If Chuuya hadn't been strictly trained on manners by the very lady infront of him, he'd say something like 'duh. i fuckin have too.' But he's not suicidal.

 

"You know what I mean." Kouyou clicked her tongue to the top of her mouth. "Unnecessary time with him. Going to that little run-down arcade, sleep overs — all nighters," She emphasized the last bit with a raised eyebrow and an unimpressed look.

 

"I don't see how that's essentially an issue?" Chuuya, sort of, cut her off.

 

Kouyou sighed, and used the moment of silence to take a sip of her tea. Which she prompted Chuuya to do as well. "It's no issue that your doing normal teenager activities. It's a matter of who your with when doing it. Dazai, hes.. a bad influence."

 

Chuuya knows that. But c'mon now, Kouyou! They're in the port mafia. They kill atleast five people a day for payment, how bad of an influence could a killer have on another killer?

 

"I think it'd be best if you didn't spend so much time with that boy. It's for the best."

 

"Wait, excuse me," Chuuya paused for a moment. "The best for who? You?"

 

Kouyou didn't exactly like the attitude he was giving her, so she said something about it. "I'm just saying. He's a bad individual and would undo all of the training you've had."

 

"Oh, so that's what this is all about. You want me to stop hanging out with him so you can have a better control of me."

 

Kouyou gasped, her calm face faltering. "That is not it-"

 

"Stop, kouyou." Chuuya, actually did, cut her off. "I could excuse your obsessive behavior before because I was a kid — but I'm eighteen now. You don't get too push and pull me around anymore."

 

"Chuuya!" kouyou's voice raised an octave.

 

Then, he stood up. "I'll come back when your able to realize that I can make my own decisions. Bye."

 

The door shut as Chuuya left, leaving Kouyou in silence. Sighing, as she continued to drink her tea alone.

 


 

 

"You see, Dazai-kun," Mori's dumb voice said.

"I believe that this addition could help out the port mafia greatly. Don't you agree?"

 

The older man pointed to a map that looked akin to a blueprint, his strangely polished nails tracing the marks along the paper.

 

Dazai sighed, "No. This building is in the port mafia territory, but it's defense is already low. So low, that it's already been attacked once before." He pointed out.

 

Mori had called Dazai in to discuss the possibility of stretching out the port mafia grounds. Preferably in a smaller base that is blended in enough to be seen as just any old building — when in reality, it would be a safe base for members on expeditions.

 

"It'd be enough of a hassle to get the gangsters out of this area. Actually, I think here," Dazai pointed to another small hut nearby that was much more public and not as guarded by strange gang members, "would be a much smarter location. It's much more natural and would be seen as just any house. We wouldn't need as much protection here either."

 

Mori hummed out, his eyebrows raising ever the slightest to symbolize that he was taking it all into consideration. "I see. A true genius you are, Osamu-kun."

 

"I told you not to call me that."

 

Instead of a verbal reply to Dazai's irritation, they were interrupted by a strong knock on Mori's door.

 

"Boss. I'm comin' in." A certain someones voice rang out, all high pitched and making Dazai's ears bleed.

 

As the unfortunately pretty ginger walked in, Dazai's face went from blank to raw disgust. "Ugh," Dazai groaned.

 

Chuuya only spared Dazai a sharp side-eye before returning his attention back to Mori. "Hey, boss. I got a question."

 

Mori raised an eyebrow in interest, leaning his head on his hands which were propped up by his elbows on the desk beneath him. "Go on, Chuuya-kun."

 

Chuuya then went on about a 'break,' or something like that. Dazai wouldn't know, considering he blocked out every sound but his own heartbeat the moment Chuuya started speaking. It felt like an eternity before Dazai was finally snapped out of his trance.

 

By none other then Chuuya fucking Nakahara flicking his nose. "Ow!" Dazai grumbled, slapping away Chuuya's hand.

 

"What the hell's up with you?" Chuuya mumbled, looking the other up and down with an annoyed frown ever so apparent on his face.

 

"I don't know what Chuuya's talking about." He quickly replied, to which Chuuya grabbed him and yanked him out of Mori's office.

 

Atleast, not before waving to Mori and sayinf his goodbyes.

 

Now, what the hell did Chuuya want?

 


 

 

I'll tell you what he wants. He, well — less Chuuya wanting anything and more Mori wanting it — told Dazai on the trip to Chuuya's dumb little apartment in the Port mafia executive dormitory. Apparently, while Dazai was zoning out, Mori suggested that the two go on a tiny little vaycay for a day or two to hang out. It seemed strange that Chuuya would even agree to such a thing. Or, atleast, it did until you realize that Chuuya practically kissed Mori's shoes clean every conversation with him.

 

So, here they were. Sleep overs weren't unusual, but they tended to be less for work, and more for just the thrill of being teenagers and having fun.

 

Dazai, of course, had spare clothes in Chuuya's strange little walk-in-closet. Which is why he wore a black shirt that had some kanji writing on it, with baggy gray flannel sweatpants. His binder was still on, of course, since he rarely ever took it off — even if that was unhealthy. However, some of his bandages were off. He only ever showed his scars around Chuuya. Because he could trust him.

 

Chuuya, on the other hand, did not have his binder on. He was comfortable with and without it anywhere. He had on a similar outfit, but instead of sweatpants he had long black shorts and a gray shirt.

 

Nights like these were normal for the two. Hanging out while binging stupid movies. Said movies ranged from comedy, horror, folklore, to even romance. Putting on '365 days' was an inside joke between Dazai and Chuuya that always instigated something.

 

Little known fact; these two have definitely fucked before. Well; technically, their first time together was a few months ago when Dazai turned 18. They, however, have been sneaking around and doing corny little relationship things in secret though. Like kissing, holding hands, cuddling, making food for each other, and what not. They just didn't have the official label yet.

 

Anywho, their first time was because of the 365 days movie. Dazai was complaining about how unrealistic it was, so Chuuya had to kiss him to shut him up. That led to Dazai kissing Chuuya in a desperate manner, which then les to actual sex.

 

Despite the two being afab, they made it work.

Nights where Chuuya would have Dazai writhing in tears, covering his face in embarrassment while Chuuya's fingers thrusted in and out of Dazai; bringing him to his fifth orgasm and second time squirting, and nights when Dazai would eat Chuuya out for hours on end simply because Chuuya tasted absolutely divine — they were all proof of their creative ways to pleasure each other.

 

And tonight was no doubt one of those nights.

 

But this time— they used toys. Not the vibarator that Chuuya would abuse Dazai's clit with, not the ropes or hand cuffs, no. It was something completely different.

 

Chuuya had brought a eight inch strap-on that was around the same color of his skin, with visible veins and all. And fuck, was it thick.

Chuuya knew that just two of his fingers was enough to get Dazai whining and begging for him to slow down — but a false dick that was way wider then three of his fingers? Definitely enough to have him passing out.

 

"Mmh," Dazai sighed as Chuuya slowly pressed kiss after kiss on his body. Chuuya loved to mark up his property, even if Dazai didn't particularly belong to him. He'd even argue it was the other way around.  "Hurry up."

 

The ginger just sighed, rolling his eyes as his fingers slit down to flick Dazai's bean. "So impatient, doll. I got a surprise that I know you'll like."

 

Dazai let put a soft gasp mixed with a moan at the intrusion of Chuuya's fingers "yeah? Now I really wanna see."

 

He ignored Dazai's whines and pleads as he fucked and scissored the gingers pussy open wide— wider then he's usually go.

 

"A-Ah! Slug-" Dazai moaned, arching his back. Found it.

 

As if something switched in Chuuya's gentle pace, he stated roughly rubbing against the sensitive bundle off nerves inside of Dazai, causing him to throw his head to the side and attempt to close his legs shut around Chuuya's fingers.

 

"Ffuck!-" Dazai yelped, his hips thrusting into the air as he grinded down on Chuuya's fingers.

This was nothing new to him, of course. But fuck, it always had Dazai moaning like a virgin each and every time.

 

Chuuya lazily looked up at Dazai, the brunette's eyes half lidded and filled with tiny tears. His pink lips blown wide and slobbered in drool deliciously.

 

"Fuckin' loud ass," — because, honestly, Dazai really was being very loud — "you're gonna wake the entire port mafia up at this rate."

 

But Dazai couldn't care less. All he cared about (or could think about) were Chuuya's rough hands abusing his prostate and clit all at once, at a rapid pace as well.

It all had Dazai wondering. What did Chuuya want to try out with him that was so important that he had to have his cunt filled with not one, not two, but three of the gingers fingers?

 

"Alright, I think you're good now." Chuuya mumbles, pulling his fingers out slowly, but not after giving Dazai one last surprise rub.

 

Finally, Dazai could breathe. He propped himself up on his elbows. "For what?"

 

Chuuya merely smirked, and pulled his pants down. Then, he grabbed something.. It looked like a dildo, with a strap attached to it. Was Chuuya seriously going to..?

 

"A strap on." Dazai spoke, his voice flat in surprise. Of course, he was expecting something extraordinary like this. But he just wasn't expecting an actual strap-on.

 

"Wow," Dazai sat up a little, looking at it. "you've really outdone yourself this time, huh?"

 

"Sure have. Best part is that the part where I's put it on," Chuuya moved it to show Dazai. "It has a thing here, so whenever I move my hips it'll rub against me. That way we both get pleasure."

 

Dazai nodded. How neat, huh? "So, you couldn't of just told me instead of making a show on it?"

 

His only response was the raising of an eyebrow and a half-hearted glare he was sure meant 'be for real' instead of anything serious.

Quickly and skillfully — Dazai'd have to ask about that after — Chuuya put it on.

 

It looked a little funny, but it helped that it was similar to his skin-tone. "Lay down. We're takin' this slow, kay?"

 

The taller quickly lied down ever so obediently, nodding afterwards. He had to sniffle back a moan as he felt the tip of the silicone dick rub his clit, probably gaining the wetness for a makeshift lube. Chuuya would do something so stupid but hot like that, wouldn't he? Dazai also had to snicker back a chuckle at that.

 

"It might hurt. Color?" Chuuya asked, leaning down to kiss Dazai's neck while aligning the dick to his hole.

 

"Green." Dazai moved his neck to let Chuuya have more access.

 

Chuuya, nodding, pushed in slowly. At this point, it was just the tip in and Dazai was already curling his toes and biting his lip. A strained moan slipped out during the pause of comfortable silence.

 

Chuuya groaned, and pushed in more. Dazai was able to take Chuuya's whole hand, don't ask please, so the thickness was nothing. It was more so the length that had his tummy twisting uncomfortably.

 

"Wait.. yellow," Dazai put his hand on Chuuya's chest, pushing slightly.

 

"Alright,"

Chuuya murmured, stopping his movements to let Dazai get comfortable and used to the feeling.

 

A few moments pass, and Dazai blinks, nodding as he pushed his hips down a little, signaling that Chuuya could move. "Green."

 

With that, Chuuya pushed in more. Still careful and slow, as if Dazai would break at the simplest of touches like a porcelain doll. Hell, like this, he looked as pretty as one.

 

Dazai gasped, and wrapped his legs around Chuuya's waist. "Right there! Fuck, r-right there!"

 

Chuuya raised an eyebrow before rolling his hips on thats spot again. It's probably his g-spot, if Chuuya had to take a wild guess. Dazai was known to have a perfect poker face, but it was way harder for him to hide his true feelings when he was in the mist of sex. That's another con Chuuya would have to add to the imaginary pros and cons board of hanging (pun not intended) with Dazai later on.

 

Perhaps after he snapped out of the beautiful euphoria that was Osamu under him, tears streaming down his face as he kicked and moaned, hips stuttering like crazy to the mere feeling of Chuuya's (fake or not) cock inside of him.

 

He'd picked up a rougher pace, bending Osamu into a mating press, forcing the dick deeper inside of Dazai.

 

"Ahhngh! Chuu~ ♡︎ !" Dazai's sweet moaning voice sang out, scratching the latters back with such ferocity it felt unreal.

 

In another POV, Chuuya was also getting close to cumming. That stupid bump kept rubbing his clit perfectly, causing Chuuya's hips to stutter as his hold on Dazai's body becomes tighter.

 

Dazai was already on the brink of it. All he needed was just one tiny push over the line he was treading so carefully on to finally cum, preferably a messier orgasm. Depending on how Chuuya was feeling in the previous hour, it'll make him irritated or either make him love it. Either way, he gets what he wants from Chuuya. Attention.

 

"Oh," Dazai gasped, his breathe hitching for a moment. "P-Please! Ughnn! I'm right there, ri-right there! Make me cum, plleeeeassse!~ ♡︎ !"

 

Blue eyes rolled, as he thrusted especially hard and gained a new speed that was bound to have Dazai coming both sooner and easier.

 

"AH!- ah, ah," Dazai moaned in time with Chuuya's harsh thrust, before his chest shot up, his hips pulsing and face going blank as he came.

 

It felt like pure euphoria — even to chuuya, as he came not even a second later as well — something filling your insides so perfectly, with the tip just kissing Osamu's womb. They stayed in silence for a good couple of moments, before finally regaining their breath together.

 

"Wanna go again?" Chuuya asked, his voice blown.

 

"Sure."
