Chapter Text
the port mafia was a cruel and evil place full of selfish and deceiving people. every day could be your last, your best friend could turn into your biggest enemy in a blink of an eye. that's how it worked for the mafiosos of yokohama.
most of them lived by the motto "carpe diem" and the infamous double black was no exception. not only were they gruesome combo in the streets, they were equally if not more passionate in the sheets. not that it was known. but hirotsu definitely knew. and he totally found out by walking in on the duo shirtless, embracing each other in the bed in their booked hotel apartment, and it was awkward and incredibly uncomfortable for all of them, especially hirotsu because technically, he walked in on his bosses, nothing could prepare him for the sight of frightened youngsters and he definitely didn't cried himself to sleep silently the next night.
before all of that, a simple mission helped those two lovebirds to take the risk in shared room.
the instructions were clear - go to thailand, negotiate with the local mafia, either bring back new connections or their dead bodies. dazai could do it on his own but mori had the annoying habit of sending chuuya with him. no matter how much his ginger partner protested, no one disobeyed mori's command.
the flight was annoyingly long and dazai could swear he heard chuuya snoring for about two minutes. they kept on bickering and after leaving the plane they met up with hirotsu who arrived a week before to examine the local streets. he also booked a grand hotel room with two separate bedrooms inside, a nice view on some park nearby and an actuality functioning AC. this was luxurious compared to the usual hotels PM booked for their executives. dazai didn't even complain about sharing the king sized bed with his short partner.
"chuuya is soo tiny, i'll still have plenty of space left!" dazai teased with bright smile on his face.
chuuya kicked him in return.
the mission went splendidly well, not only they negotiated new contacts, they also managed to kick a few idiot's butts. chuuya was over the moon and dazai felt quite ecstatic himself.
once they returned the sun already set and after stuffing their stomachs with cheap noodles they lay down on bad.
"so, what's the plan for tonight?" dazai chirped as he dragged his index finger across chuuya's freckled arm. both of them undressed and showered after they came back, wearing long tees and boxers as pyjamas.
"i dunno, are't ya the one in charge of plans?" chuuya mumbled lazily into his pillow, lying deadly still. he was tired after the long day, and his annoying partner made every second even worse.
"hirotsu's not comming back 'till mornin'" dazai reminded his dear partner, in case chuuya couldn't catch on.
and he did. quite quickly.
with raised brow, the smaller boy propped himself on his forearms and silently asked dazai: "are we seriously doing this?"
dazai just chuckled and shrugged his shoulders, as if it didn't matter to him.
bastard.
chuuya didn't assume they would fuck in a shared hotel room but if dazai was the one suggesting it - surely he got this calculated and knows it's safe to forget about their temporary roommate.
what could possibly go wrong?
"take your shirt off" chuuya commanded. not even trying to be subtle, of gentle, hell, dazai didn't deserve that princess treatment.
instead he let the boy undress, showed him back in the sheets and climbed on top of him.
now for the second myth.
even if people were to assume soukoku are more than platonic buddies, never would they have guessed that chuuya was the one in charge in bed. yet somehow, it worked perfectly.
in the real world, dazai had to have everything under control. every single thing had to be calculated, happening according to his plans. the demon prodigy was a little puppet master, scheming and manipulating and it was tiresome. and hey, everyone needs a break.
chuuya, on the other hand, felt like he never had the privilege of being one step ahead. he felt as if he had to constantly catch up, let people toy with him and deal with it, face the consequences of dazai's decisions, follow dazai's plans, never foreseeing the opponent's tactics.
so it was a nice change to finally command for once.
"did you bring condoms?" chuuya asked.
"no, i didn't expect to fuck on a mission, how dirty would i otherwise be?" dazai blinked innocently, it almost convinced chuuza, almost.
"yeah for sure. so what now?" they were losing the precious time by talking.
"are you clean?"
chuuya blinked: "i mean, i am. are you?"
"yep! got checked yesterday" dazai giggled and chuuya wasn't sure it surprised him.
"oh course you did. dazai i swear i'll kill you one day! but before that i'll fuck you hard many more times" chuuya growled and pressed down on his wrists harder.
"chuuya don't hurt little old me!" dazai called out but it was pretentious. everything about his bandaged partner was stupidly pretentious.
"oh i am so going to hurt you"
he flipped dazai so his back faced him, lifting his ass up, with one swift move he pushed his boxers to his ankles and without any prep whatsoever he sticked one finger inside his hole.
"chuuya~" dazai whined and shut his eyes tight as the redhead's finger started to move inside.
chuuya added a second finger and stretched dazai's hole out, enjoying the rough treatment he gave him.
dazai seemed to enjoy it too because his toes curled and his hips kept on wiggling, which was annoying, so chuuya spanked his ass harshly with his other hand, earning a surprised moan from the taller one.
"chuuya it hurts" dazai could've been talking about the slap on his ass, of the dry fingers in his butt, chuuya used zero lube.
"you could've at least spat on your fingers" dazai whined and moaned and chuuya started to get sick of his ungrateful bratty mouth.
he took his fingers out and slapped each of his cheeks again. they got rosy red and it was a beautiful sight.
chuuya took off his own boxers, already semi hard, and positioned himself against dazai's entrace.
"say when" chuuya murmured.
he didn't wait for the actual when though.
he just slammed hard inside, his skin slapping against dazai's.
"aaaah" dazai let out loud obscene noise as he shot his head back, eyes closing shut and mouth wide open.
chuuya started to fuck him hard in ruthless pace, grabbing his hips to slam them back into him. it felt like heaven and hell altogether. dazai felt tight around him and even though he kept on letting out pained noises, he noticed the leak comming from his dick.
"i knew you like it rough but this, oh dazai if only the thai mafia knew" the words just left his mouth and he started to feel ashamed but then dazai hit back wit the: "would you let them fuck me?" and chuuya groaned and tilted his head back and did the split moment decision he won't let dazai walk tomorrow.
"no one besides me will so much as touch you, shittyzai! do you understand?"
he grabbed his hair and yanked him up, biting into his neck and licking it gently just to bite it again. he didn't wait for dazai's weak "yes". dazai panted as he had to arch his back in this position and felt chuuya's free hand playing with his nipple and his lips kept on sucking the skin on his neck and it was so overwhelming he could cry.
then chuuya turned him around so he was facing him and pushed him back into the bed so hard he bounced a little. he opened his legs for chuuya so quickly the smaller couldn't keep in a mocking "slut" and as he started to pound into dazai again, he wrapped one hand around his neck and other against the flat of his belly.
this made dazai slightly uncomfortable. it made him feel owned. the most delicate part of his body was in hands of a raging god, and he wasn't scared to press down. dazai started to see stars and he let out a bunch of lewd cries and chuuya finally hit his prostate and dazai felt so lightheaded he imagined himself levitating. chuuya noticed the change in his behaviour, how he suddenly got more vocal and then silent when he missed. he set his mind to hitting dazai's prostate with each thrust and dazai finally broke down. he howled a loud "chuuya!" and came all over their stomachs. without chuuya touching him even once.
"just like a fucking whore." he pressed down on dazai's neck unnecessarily harshly. chuuya didn't stop, on the contrary he railed his partner even faster, chasing after his own high. dazai sobbed overwhelmed with pleasure, whimpering as chuuya's thrusts got messier and more shallow, one hand on dazai's wrists, keeping them over his head crossed together just to show how submissive he is, other on dazai's side, pressing harshly to leave marks.
he came shortly after, with deep thrust in that made dazai choke on his sob, and after riding out his orgasm chuuya finally got off.
after catching a breath he immediately pushed himself up on his elbows and looked at his partner, examining how he looked. dazai stayed exactly in the same position chuuya left him in.
hair sweaty, sticking to his forehead and pillows bellow, eyes watery, half closed with stars and hearts in, cheeks flushed, a drool coming from corner of his mouth finishing the look off. he looked so incredibly ruined. it was perfect. no smart remarks for once, just quick breaths leaving his mouth.
he didn't look mentally present, so chuuya gently voiced: "hey, are you okay?"
dazai blinked back to reality and looked at his partner.
"yeah. just a bit sore from chuuya dry-humping me."
"oh i'm sorry asshole. you looked very dry-humpable" they both laughed.
chuuya pressed his palm against dazai's cheek and caressed it gently, lovingly.
"you have to bring condoms and lube next time you plan on fucking okay?" chuuya reassured him
"mhm" the latter murmured, already drifting off to sleep.
"g'night mackerel" chuuya pressed soft kiss against his cheek, brushing hair from his face and combing through it. dazai didn't answer, instead his breathing slowed down and his face relaxed.
chuuya got up to get some water and towel to clean dazai, taking care of his cum covered body. he always liked the aftercare. dazai trusted him completely to let him do whatever while he was long asleep and chuuya acknowledged and appreciated the faith in their bond. it was special to him. he took a brisk shower and climbed back under the covers with his other half od double black, hugging the small of dazai's waist as he let weariness take over him, falling into another dreamless night.
and then the morning came and hirotsu with it, and it wasn't the coziest morning they could have, but it was all okay because it was them.
