Work Text:
It started, as most things in their weird relationship do, as a joke.
Dazai had just wanted to tease his old partner, give him a sense of normalcy. They were working together again after four long years apart, but with the way they behaved, it was as if Double Black just took down another organization yesterday; like no time passed at all.
Except time did pass and Chuuya wouldn’t let Dazai forget about how he ‘betrayed’ the mafia and ‘abandoned’ him. Even with the familiar bickering, there was still a wide gap between them, and Dazai yearned to close it.
He had been in a very dark place when he was with the mafia, and sometimes Chuuya still brought out that more sinister side of him. Such as how Dazai swore to himself that he wouldn’t do anything to mess with Chuuya’s actual feelings this time. He would resist fucking him or toying with him, only teasing him in a wholesome, not as manipulative way, avoiding sex altogether. To show that he was reformed.
However, Chibi really loved to push his boundaries like no other person on the planet did. He just made it so easy. So fun.
Dazai never had more fun than when he was teasing Chuuya, playing with that fire. He never felt more alive than when the other bit back at him and made Dazai think for a second that he’d finally snapped and would make good on his promise to murder the bandaged man.
Despite his hopes that maybe he was a changed man and not the unholy demon he was years before, there were still moments where he felt like a true sadist for enjoying tormenting him. It made him doubt his humanity, which was normal for him, but never a welcome feeling.
This though, he swore he’d meant it as a joke.
It was just supposed to make Chuuya snarl something about how he’s ‘not a damn dog’ or maybe make him throw a punch at Dazai.
It wasn’t supposed to…
This wasn't supposed to happen.
-
They were sitting in the office at the ADA together. Not a completely rare occurrence nowadays, especially since the Port Mafia was still allied with the Armed Detective Agency and that’s given them an excuse to see each other more. Chuuya was just there to collect some reports that Dazai was supposed to finish writing up, but of course got sidetracked on.
Instead of doing their jobs, they sat behind Dazai’s desk tossing jabs back and forth while the rest of the Agency ignored them, already used to their typical nonsense.
It was something stupid. Something so incredibly stupid.
Dazai was entertaining himself with making paper airplanes out of the work he was supposed to be doing, making Chuuya go collect the reports that he was supposed to take back to the mafia.
“For fuck’s sake Dazai, can you actually do your job for once?” Chuuya barked, grabbing a plane out of the air before it could stray onto someone else's desk and force the mafioso to interact with other Agency members.
“I am doing my job. This is just how dogs retrieve things, like playing catch. I’ve gotta keep you in shape somehow.”
“Worry about your own shape, noodle arms.”
“Boo, that was weak.”
“Fuck off.”
They’re very lucky the rest of the office wasn’t paying attention to them, because the next few minutes were thick with tension at the following exchange:
Dazai folded another airplane and threw it in the opposite direction of Chuuya, chirping, “Go, fetch chibi!”
And although he mumbled complaints the whole time, the redhead still did as told and went to get the document.
It was when he got back to the desk that it all went to shit.
Chuuya slammed the paper on the desk and glared at Dazai, but the bandaged man simply smiled delightedly, patting him condescendingly on the head.
“You got it! Good boy~”
And maybe it was his fault for the way he purred the words out, his voice maybe a little huskier than usual because of their yelling at each other earlier in the day.
In his defense though, he thought the redhead would take it as a joke, as is their usual dynamic. He did not expect Chuuya to freeze completely, a choked noise escaping his mouth that sounded a little too much like a whimper. Pink quickly lit up his cheeks and his eyes dilated, blue swallowed up almost completely with black.
Dazai had known the other long enough to know the telltale signs of Chuuya being turned on.
It was clearly a shock to both of them as Chuuya didn’t even have a verbal comeback, lips parted in shock, nearly trembling where he stood. Dazai himself didn’t expect this outcome with the teasing words, and seeing Chuuya aroused for the first time in a long time did things to his own body that he had been trying so hard to push down. He shakily removed his hand from the other's head.
Thank god that the others weren’t paying attention, otherwise they’d have seen the two staring at each other with equal amounts of shock and lust, dumbstruck by the discovery they had both just made.
And he knows that he promised not to fuck Chuuya again, but-
“Chuuya?” Dazai prompted lightly, slowly standing up from his desk.
“Hm?” Chuuya’s voice clearly wasn’t working, the higher pitched hum of acknowledgement the only sound he could make.
“I’m going to go on a lunch break now. Would you like to join me?”
Dazai started towards the door after robotically giving his proposal before Chuuya could even respond to his stilted words, which was fine because Chuuya couldn’t verbally respond anyway, only frantically nodding his head and following the other out the door.
The abrupt and awkward exit did not go as unnoticed to the others as their previous interaction had been though. Kunikida was about to get up and yell at them to get back to work but Yosano put a hand on his shoulder, holding him down.
When looking up at her in question, she just grimly shook her head.
Kunikida didn’t want to know.
-
The walk to Dazai’s dorm within the Agency was short but it took years. They walked in silence, not hungrily clinging to each other or making out on every available surface, like the tension between them would suggest. Their gaits were stiff and their conversation, nonexistent.
It wasn’t until they got to his humble abode and locked the door behind them that Dazai dropped the mask of innocence and an evil smirk melted onto his face. He grinned back at Chuuya as the other followed dutifully into the apartment, face completely flushed and furiously avoiding eye contact.
“Shut the fuck up. Shut the fuck up. Shut the fuck up.” Chuuya spoke through gritted teeth, hands clenching and unclenching at his sides.
“I didn’t say anything, Chuuya-kun.” Dazai leaned into the other’s space despite his head screaming at him to stop this before it goes too far.
He licked his lips as he looked down at the blushing redhead, eyes roaming over his figure like he didn’t already intimately know every inch of that body. Despite himself, Chuuya shivered at the attention, biting his own bottom lip and looking up at Dazai through his lashes.
“I just wanted to let you know what a good boy~ you are.” Dazai purred, even more sensually than he did in the office, now that they were in the safety of his dorm.
The sound that came from Chuuya’s throat this time was undeniably a whine. The redhead's eyes drifted shut as he unconsciously leaned towards Dazai.
The bandaged man gently brought his hands up the other’s sides, ghosting his arms but not touching, until he got to that stupid hat atop those ginger locks, and slid it off. While one hand placed the abomination on a side table, the other ran through Chuuya’s hair, petting him much more intimately than before, his fingernails scraping against his scalp.
Chuuya leaned into the touch, opening his eyes again with a mix of rage and want swimming in those deep saltwater blues. However, he didn’t push him away.
“Fuck you.” He growled, embarrassment written all over his face.
“Hmm, maybe. As long as you continue being good for me~”
Lust was the only thing running through Dazai’s veins as he leaned down and finally did what they both craved, and closed the distance between their lips. Despite his earlier protests, Chuuya eagerly responded.
Their first kiss in four years was slow, but it was heavy with want. It was wet, Chuuya was practically drooling in his need to taste his lips, but Dazai couldn’t get enough of it. The kiss was sloppy and messy and it was everything they needed.
Distracted by the tongue working open his mouth, Chuuya barely even noticed Dazai begin to take off the mafioso’s jacket, sliding it to the ground and steadily guiding them further into the apartment. Too caught up in the sweet taste of Dazai’s lips to care that he was slowly being undressed and leaned back onto a bed.
It wasn’t until he pulled back for air when he realized the other was on top of him, one hand still tangled in his hair while the other gently stroked up and down his hip, causing him to shiver all over. Goosebumps spread over his exposed skin.
“Dazai, w-wait. Stop.” He stuttered out, not yet removing his own hands from where they were draped around the other man’s shoulders.
Like a gentleman, because that’s what he was now, Dazai did as asked and leaned back instead of doing what he so badly wanted, which was to further the kiss.
He sent a questioning look to the other, tilting his head, “Yes chibi?”
Chuuya’s face scrunched up in annoyance at the nickname, his nails digging warningly into Dazai’s back. Still, he sounded no less turned on when he responded.
“What are we doing?” He breathed out, the question almost sounding rhetorical with how much desire was clearly still present in his voice.
Dazai raised an unimpressed eyebrow.
“Making out. Obviously.”
One of Chuuya’s hands snaked back to the front of his chest and pushed Dazai back until he was sitting back on his calves. Chuuya followed him, sitting up and glaring at his former partner.
“Idiot, you know what I mean.”
Dazai let out a deep sigh.
He didn’t want to have to think about what they were doing, rather preferring to just go with what his body wanted for once instead of having to worry about it. Still, his partner probably deserved an explanation.
“Look,” He started, trying to rationalize the bullshit going through his head into something other than just ‘mmmm horny’.
“This was gonna happen eventually. Don’t pretend you haven’t been wanting to do this for weeks,” Dazai snuck a hand onto the others calf as it laid on the bed next to him, gently squeezing the flesh as he slid it further up, “I don’t know how much longer I could’ve resisted you, but the way you reacted when I called you a-”
“Don’t say it again!” Chuuya quickly interrupted. Shoving his face into his hands did nothing to hide the blush as it spread across his ears and neck.
“But Chuuya~” Dazai whined, still massaging the redhead’s leg, “You have such cute reactions!”
The shorter man ripped his hands away from his face and shoved Dazai onto his back, pouncing to straddle the other’s hips as he glared down at him. Though his face screamed murder, Dazai was able to feel the undeniable bulge pressing against his own hardening erection from where Chuuya sat on top of him.
“Shut up! I’m not cute.” Chuuya pouted cutely.
Dazai couldn’t help but coo at that, his hands coming up to rest on Chuuya’s upper thighs, fingers toying with the crease between where his legs connect to his hips. Chuuya swallowed heavily above him, subtly grinding down and trying to make it seem like he was simply adjusting his position. It didn’t fool either of them.
“I’ll stop calling you cute for now if you take off your shirt.” Dazai bargained, desperate to keep things moving along. His fingers skimmed the bottom of Chuuya’s untucked shirt, itching to touch the smooth skin of his waist.
Chuuya rolled his eyes, but like with most of Dazai’s requests, followed through anyway. He didn’t bother unbuttoning the entire thing, just loosening the top few buttons and pulling the rest of it off over his head. Before the shirt even hit the ground, Dazai’s hands were roaming his now bare chest, sliding over the hardening nipples.
“Good boy.” Dazai rewarded him, smirking.
From this position, he could distinctly feel Chuuya’s erection twitch against his own and had to keep his expression from getting too giddy.
He’d always been pretty dominant in the bedroom, but Chuuya was a firecracker who refused to bend easily. They were both brats and neither of them wanted to be the one to submit first. Finally finding the trigger words that could control the man was like getting exactly what he wished for on a Christmas morning.
In lieu of responding with anything as humiliating as a moan, Chuuya practically fell back down atop him and resumed their kiss with a frenzied passion.
This time the redhead’s wandering hands found their way to Dazai’s still clothed body, unbuttoning his vest and shirt with obvious impatience. Dazai chuckled into his mouth, groping Chuuya’s bare chest before sliding down to squeeze his ass, garnering a groan from the other man.
His hips started undulating downwards, rubbing their straining bulges together at an agonizing pace. Chuuya’s weight on top of Dazai quickly sent all of his blood south, to the point where he started to feel light headed both from the lack of air in the kiss and the sudden rush of blood. It was both dizzying and grounding; Chuuya’s movements. Whatever feeling it gave him though, Dazai happily accepted.
He reluctantly pulled away from the kiss, a string of saliva hanging between their swollen lips and taunting him for whatever’s to come. As Dazai started assisting with taking off his own shirt, he looked up at Chuuya sitting on top of him with the sort of reverence one would see from someone worshipping a god at an altar.
“Do you want to get fucked or fuck me sweetheart?” He asked as soon as his shirt was off, revealing the slightly disheveled bandages that were covering his torso.
Chuuya paused for a moment to think before sliding off of his position straddling the other, almost drawing a whine of protest from Dazai.
“I want to fuck you so hard you can’t speak, sweetheart.” The redhead smiled sweetly despite the darkness in his voice. Dazai couldn’t help but gulp as his heart stuttered.
“Yeah.” He nodded, unable to say anything more without embarrassing himself.
Now that he was free to move without Chuuya sitting on his lap, Dazai quickly shimmied out of his pants and underwear, exposing his erection to the hot air. Chuuya followed his actions, shucking off his own trousers and briefs with a sense of urgency. Before letting the pants hit the ground, he fumbled around with the pockets, pulling out a condom and small packet of lube.
The bandaged man gave him an amused look, to which Chuuya simply rolled his eyes.
“Look, I’m a single man in my early twenties. Of course I carry this shit around.” Chuuya defended, crouching over Dazai as the bandaged man settled down on the bed, spreading his legs shamelessly for the redhead. Chuuya’s mouth went dry at the sight of Dazai’s cock lying innocently against his stomach, his puckered hole exposed.
“Aw,” Dazai pouted, “and here I thought chibi had brought them specially for me.”
“I didn’t plan on this happening! If anything, you probably set this whole thing up.”
Dazai managed to make an incredibly innocent expression despite his hands drifting down to spread his cheeks wider, encouraging Chuuya to hurry up and coat his fingers in lube.
“How was I supposed to know you were weak to those words?”
“I’m not weak to any words, dipshit.” Chuuya hissed, finally giving in and kneading the surface of his ass only briefly before sinking his middle finger fully into his tight heat.
“Hmm, is that so?” Dazai smirked despite the flush in his cheeks and Chuuya’s finger hooking in and out, “You’re not being a very good boy right now.”
In retaliation for that comment, Chuuya pushed in a second finger, immediately going for where he knew that sensitive spot inside the other was. Dazai let out a yelp, body jerking at the pressure as Chuuya tried to ignore how his own cock twitched at both the sight and his partner’s words.
Whatever response Dazai would’ve had to that intrusion was swallowed up as Chuuya leaned over, resuming their sloppy kiss as he continued to scissor his fingers in Dazai’s hole, making sure to brush against that little bundle of nerves every other thrust just so he could hear the other try in vain to stifle his moans against their mouths.
Their tongues intertwined in an aggressive dance while Chuuya continued to finger Dazai into oblivion. Dazai’s attention drifted between the taste of Chuuya in his mouth and the feeling of someone else's fingers exploring his insides.
Finally after adding a third finger, Dazai let out a petulant whine and pulled away from the kiss again, gasping for air. He felt full, but not nearly full enough. His eyes flashed up to Chuuya in a challenge.
“Fuck me.” He demanded with no pretense.
And how could Chuuya say no to that?
Retracting his fingers from the now wet hole, Chuuya wasted no time opening a condom and rolling it onto his own painfully hard length, giving himself a few jerks to prepare as much as he could for the pleasure he knew was coming. They shared a single look between them to confirm that this was happening, this is what they both wanted, and when neither of them had any doubts on their faces, Chuuya finally pushed the tip in through the rim.
The redhead cursed, unused to the unbelievable tightness of Dazai’s entrance squeezing down on his cock. In response, Dazai smirked up at him despite the way he was also heavily panting, cheeks flushed with life.
“Such a good boy~” He teased once again, sticking out his tongue and purposefully clenching the muscles at his rim to make Chuuya yelp and glare down at him.
Ignoring the voice inside his head that was telling him to slow down and wait for Dazai to properly adjust, he slammed the rest of the way in, relishing in the look of open mouthed shock and pleasure that showed on Dazai’s face before he was able to hide anything underneath his usual mask of composure.
They both let out low groans as he was fully inside. Chuuya, because he’d forgotten just how good it felt to be buried in Dazai’s ass, and Dazai because he could never quite get used to the feeling of being so full. Especially after being empty for so long.
Any hookups he’d had since leaving the mafia, he usually topped. Being a bottom for a stranger would have just been too… vulnerable for him. But he trusted Chuuya.
Bottoming for someone he felt something more than just physical attraction towards was an entirely different feeling altogether, but one he much preferred to random hookups.
It was a sensation they both missed dearly.
Dazai let out a strangled moan when Chuuya shifted slightly to get a better angle, his length just barely brushing against his prostate.
“God, move.” He tried to sound bratty, but it came out more like a plea.
It was Chuuya’s turn to smirk at the other’s loss of composure, thrilled to see the usually in-control man show any kind of desperation. Giving another cheeky little thrust before pulling back almost completely out and slamming back in, Chuuya started an agonizingly slow pace in and out of that tight heat.
The slow pace didn’t last long though as Dazai brought his hands up to Chuuya’s hair, dragging his nails through and tugging it harshly. Chuuya moaned, quickening his thrusts to the silent demand without another word.
The sound of wet skin slapping filled Dazai’s agency dorm room, joining in with their own breaths and moans.
When Chuuya finally found the right angle to thrust directly against Dazai’s prostate, Dazai whimpered, pulling even harder at Chuuya’s crimson locks as he once again sped up his pace.
“Y-yes! Fuck, Chuuya, right there...” He looked up, crimson eyes half lidded at the sight of Chuuya moving above him, not wanting to miss a single second of this.
Sweat glistened on the other man’s chest, his skin flushed pink and eyes closed as he took his pleasure from the other. He was beautiful.
Another particularly hard thrust had his back arching off the bed, a choked cry escaping his throat.
Fuck, he loved this.
The stars bursting behind his eyelids with every slam inside him, the ache of his hole as Chuuya’s cock dragged against his inner walls, the beautiful sounds the man on top of him was making as he felt just as much pleasure.
He knows he promised not to fuck Chuuya now that he was a reformed man but…
It felt so good.
How could something wrong feel so good?
“Shit, you’re so tight.” Chuuya cursed, finally opening his eyes to view the masterpiece beneath him.
Dazai looked no better off, lips parted as he was unable to speak without it turning into more breathy moans, face all red and brown eyes near tearing up as he lost himself in pure bliss.
The picture went straight down to his hardness, only making the feeling of fucking into him that much better.
“G… good-” Dazai tried to speak, desperate to take back some control over the situation, but cut himself off with a long moan as one of his hands left Chuuya’s hair to pull at his own leaking hard cock laying untouched between their sweaty bodies.
The heat pooling in his stomach set his whole body on fire. He knew he wouldn’t last much longer, already feeling the orgasm creeping up.
The hole clenched tighter around Chuuya’s dick, the only other sign that Dazai was close. Chuuya increased his pace until he was hammering into Dazai, dropping his body closer to the other’s so they were chest to chest, with Dazai’s hand still moving frantically to get himself off. Getting Dazai to cum was almost as pleasurable as when he orgasmed himself, and he wanted to make it good.
“Go ahead, be a good boy and cum for me.” Chuuya whispered into his ear, turning the others' own words against him.
Dazai gave himself two more jerks before he was cumming with a desperate cry, mind spinning and hole twitching around Chuuya’s cock as cum spilled over his fingers. His body curled up around Chuuya, pulling him impossibly closer as waves of pleasure pulsed through his body.
The feeling, along with the sounds of both Dazai’s whines and their bodies slapping against each other was enough to send Chuuya over the edge. After only a few more thrusts to let Dazai’s orgasming body milk his cock some more, he was frantically pulling out and ripping the condom off. As much as he would love to cum inside the other man, he'd rather it be without a condom, so he could see his cum dripping out of Dazai's abused hole.
He hurriedly shuffled forward and jerked his throbbing length over Dazai’s face as the bandaged man was too exhausted to resist. With a choked groan, he was cumming too, streams of hot cum shooting over Dazai’s cheeks and lips, still parted as he tried to catch his breath. One streaked over his closed eye, causing Dazai make a disgruntled face as he was coated in cum.
Chuuya kept tugging until nothing more was coming out and he was too overly sensitive to continue, finally falling back onto the bed as he came down from his own orgasm.
They both lay there for a second, panting and spent, before Dazai whined dramatically, wiping a finger over the cum on his cheeks and over his eye to rub it off onto his already ruined sheets. The cum on his lips, he tried subtly to lick up, although Chuuya’s self-satisfied smirk told him he wasn’t fooling either of them.
“Never calling you a good boy again. You’re such a dog.” He complained, shakily propping his tired body up on his elbows. After orgasming, he ached to cuddle with Chuuya, but there was no way in hell he would initiate that contact.
“You’re the one that was begging me to fuck you.” Chuuya grumbled, reading Dazai’s mind and crawling back until he collapsed on top of Dazai again with an ‘oof’, nuzzling his head under the bandaged man’s chin.
Dazai sighed exasperatedly, but brought up a hand to pet the others' hair anyway.
“I didn’t beg.” Dazai petulantly denied.
Chuuya snorted but didn’t respond, letting his eyes drift shut as he lay completely boneless on top of the other man. They lay there for a minute as they each caught their breath, listening to each other’s heartbeats through their pressed together naked chests.
The brunette had to ruin the mood before it got any more intimate than it already was.
“Hey, slug,” Dazai poked Chuuya’s cheek, “Don’t fall asleep on me.”
“Ugh,” Chuuya grunted, making no movement to remove himself from atop Dazai’s chest, “You’re so annoying.”
Dazai hummed in agreement, taking the mafiosos inaction as a sign to keep cuddling, despite his head screaming at him to cut off contact. He wrapped his arms around Chuuya’s limp figure like an octopus, pulling him closer against his chest as he fought off the very sleep he'd warned Chuuya against.
Whatever issues they needed to work through could wait until morning.
Dealing with the fallout of this little excursion was a problem for Tomorrow Dazai.
Today, he could be content to rest with his dear partner.
