Work Text:
Chuuya knew when he heard the knock on the door what Dazai wanted. He’d expected it when the reminder popped up on his phone that morning with his alarm: Dazai’s Birthday.
He opened the door to Dazai’s stupid cocky grin and folded his arms in front of his chest, deciding to play dumb anyway. “What do you want?”
“Chuuya, is that any way to greet me on my special day?” Dazai asked. “I’m shocked at how rude you are! Or did you forget?” His eyes went wide in mock horror. “My own partner, forgetting my birthday!”
“Ah yes, the reminder that you’re like a cockroach who’s somehow managed to live another year longer.” Chuuya rolled his eyes. “What’s that got to do with me?”
“Well, the cake at the Agency was nice, even if it was shaped like a dog,” Dazai said, reaching forward to twirl a lock of Chuuya’s hair around his finger. Chuuya made a disgusted noise. “But I was looking for something a little more...what’s the word? Exciting.”
“Yeah? And the Agency can’t provide it?” Chuuya swatted Dazai’s hand away.
“You know how they are,” Dazai said. “So good, which is nice but...not always what I need, you know?”
“Mm-hmm,” Chuuya said. “And what do you need?” He wanted to hear Dazai say it.
“I think you know what I need,” Dazai said.
Chuuya started to close the door, but Dazai shoved his foot forward to stop him and braced his hands against the door and the frame, preventing Chuuya momentarily from pushing it further closed. They both knew that unless Dazai touched him again, Chuuya could slam the door shut anyway and possibly take Dazai’s foot off. But Chuuya didn’t.
“You’re annoyingly persistent,” Chuuya said. “Why shouldn’t I slam the door in your face?”
“You didn’t even wish me Happy Birthday,” Dazai pouted.
“Well, if that’s all you wanted, Happy Birthday. Now leave.” He pushed the door again, this time with more force.
But Dazai shoved himself forward, hard enough that he crashed into Chuuya and almost sent them both onto the floor. Chuuya recovered enough to push against Dazai’s weight and kick the door closed behind him, and then Dazai grabbed the back of his head and pulled him close, meeting Chuuya with his lips.
Chuuya grabbed Dazai by the chin, jerking away enough to see Dazai’s flushed face.
“Chuuya,” Dazai murmured. “It’s been so long since I’ve had you.”
“And it’ll be longer if you don’t ask for it,” Chuuya snapped. “Say it, Dazai.”
“You’ll make me ask on my birthday?”
“I’ll make you beg.”
Dazai stared at him for a moment, clearly weighing his options. He licked his lips and breathed out, “Please, Chuuya?”
A shiver worked its way through Chuuya’s body and he grabbed Dazai by the tie, letting go of his chin.
“Bedroom. Now.”
Dazai seemed happy to follow as Chuuya pulled him into the bedroom. His bed was still messy from when he’d gotten up, and now he was glad he hadn’t bothered to make it. He hastily gathered what they needed and saw that Dazai had already tossed his jacket and waistcoat aside and was working on the buttons of his shirt.
“Desperate,” Chuuya smirked, placing his hat on the dresser. Shirt and pants dropped to the floor, and Dazai started unraveling his bandages. It had long since stopped being strange, and Dazai no longer hesitated. It felt like a small thing, but Chuuya was grateful.
He reached up to undo his collar but Dazai said, “Stop.”
Chuuya hesitated.
A ribbon of bandages pooled on the floor at Dazai’s feet.
“I want to undress you, Chuuya,” he said.
“Huh? Isn’t it your birthday?”
“So you’re finally getting it,” Dazai said. “In that case, shouldn’t I be able to do what I want?” He made his way over, already naked. Chuuya glared up at him as he hooked two fingers underneath his collar, then smoothed down the fabric of Chuuya’s jacket before yanking it off his shoulders.
“If anything rips, you’ll pay for it,” Chuuya growled.
Dazai hummed and tugged at the straps crossing Chuuya’s chest, then undid the buckle and let them fall to the floor with a soft thunk. He began working on the buttons of Chuuya’s waistcoat.
“Why does Chuuya wear so many layers?” Dazai murmured. The waistcoat dropped, too, and Dazai’s fingers deftly undid the buttons of Chuuya’s dress shirt.
“You’re one to talk,” Chuuya scoffed. “Let’s not even talk about the outfit of bandages you wear underneath your clothes.”
“I’m lucky,” Dazai said, “that Chuuya doesn’t decide to make things so hard.”
“You’re damn right you’re lucky,” Chuuya said.
Dazai paused, glancing at Chuuya’s face. His lips twitched and for a moment he looked like he wanted to lean forward and kiss Chuuya. But then his eyes flitted back down, and he pulled off Chuuya’s shirt.
Pants were next, and Dazai pushed Chuuya onto his back on the bed once they were off. Chuuya reached up again for his collar, but Dazai grabbed his hand and kissed the knuckles.
“Keep it,” he said.
“Whatever,” Chuuya muttered.
Dazai reached for the lube.
“Hang on,” Chuuya propped himself up on his elbows. “What are you-”
“My birthday,” Dazai reminded him in a sing-song.
“Oh, so you wanna do all the work?” Chuuya let himself fall back. “Go right ahead.”
“No, I just want to see you when you’re working hard,” Dazai said.
“Huh?!”
“I know you can.” Dazai grinned. “Or is that too much of a challenge in this position for you? If not, I guess we can switch-”
“Lazy bastard,” Chuuya snapped. “Of course you want all the benefits with none of the--” He choked off the last word as Dazai slipped two fingers inside his ass. “Work!”
“Now now, Chuuya,” Dazai murmured, thrusting his fingers in and out. “It’s time to relax. We wouldn’t want any mishaps on my special day.”
Chuuya gritted his teeth against the gasp that threatened to escape. He wanted to wipe that smug grin off Dazai’s face, preferably with harsh words, but he knew that wouldn’t get to Dazai right now.
He jerked his hips up and Dazai raised his eyebrows, adding a third finger. It felt good, and Chuuya grabbed the sheets around him, trying not to show it. He wasn’t the one that needed to be undone here.
“Just--do it already,” Chuuya hissed.
“So impatient,” Dazai said. “Well, it’s your ass.”
Dazai removed his fingers and Chuuya took the time to steady his breathing. He watched as Dazai worked lube onto his erect dick, then knelt over Chuuya on the bed between Chuuya’s legs. Dazai’s face was already flushed, and Chuuya felt a spark of satisfaction.
Then Dazai leaned over him, bracing one hand on Chuuya’s shoulder.
Chuuya met his eyes, daring him to go in.
He felt Dazai’s cock fill his ass. Dazai gave an experimental thrust, but Chuuya swatted his arm.
“I thought you didn’t want to do any work,” he said.
Dazai laughed. “If you insist.”
Chuuya ground his hips up and Dazai shuddered, his breath coming out in a soft gasp. Chuuya smirked, and thrust his hips harder. Dazai bit his lip, his head bowing down as he struggled not to moan.
That was all Chuuya needed.
He thrust harder, picking up his pace, and Dazai’s body shook each time, his breath coming out in small pants. Chuuya wanted to hear him moan. He was having trouble containing his own noises. Dazai always felt so good in him, and he was sure that if Dazai just voiced his pleasure once that would be it.
Instead, Dazai suddenly thrust one hand forward, grabbing Chuuya’s collar and yanking it.
Chuuya gritted his teeth. So Dazai wanted to play that game.
Chuuya slowed down, his motions less thrusting and more rolling his hips down and then up. Dazai shook against him, choking on his breath as Chuuya refused to pick up the pace, instead sliding down, then up, then down in agonizingly slow motion.
“Ch-ch-chuuya,” Dazai gasped, his voice breaking on the last part of Chuuya’s name.
“Oh?” Chuuya managed to keep his voice steady. “Problem, Dazai?”
“N-no problem.” Dazai groaned as Chuuya moved his hips up, sliding along Dazai’s dick even slower. “I--fuck, Chuuya…”
“I can do this all afternoon,” Chuuya said.
“Don’t.”
He tugged at Chuuya’s collar again, this time a more desperate gesture. Chuuya licked his lips, a bead of sweat working its way down his temple, disappearing into his hair.
“Please,” Dazai hissed, raising his head to look Chuuya in the face. Hair plastered to his forehead, lower lip bright red, eyes bright, open, and wanting. Chuuya felt warmth flood him. He would commit this look to memory.
He picked up his pace, delighting in the shout Dazai directed at the ceiling for just a moment before Chuuya’s own high-pitched moan joined him, and together their voices merged in a symphony of pleasure as Chuuya kept going, bringing them both closer, closer, closer.
With a cry, Dazai lurched forward, and Chuuya felt a different warmth, Dazai’s cock twitching inside him as Dazai came. Dazai’s whole body jerked and he fell forward onto Chuuya, gripping his shoulders and breathing hard into Chuuya’s neck.
Chuuya couldn’t take it. He gripped Dazai’s back, his nails digging into the skin, and gave one last thrust. He saw white as his entire body exploded with pleasure, and he nearly sobbed into Dazai’s shoulder as he came.
For a moment, the two of them just lay there trying to breathe. Chuuya buried his face in Dazai’s shoulder, taking in the weight of his body and the heat against his skin that would soon cool.
He wanted to see Dazai’s face, he realized.
He tilted his head back, pushing against Dazai’s shoulders to push him up. Dazai looked down at him through heavy-lidded eyes, a lazy grin spreading across his flushed face.
“Chuuya,” he murmured. “You’re beautiful.”
Chuuya felt dizzy. “You’ve never looked better,” he slurred, surprised that he could even get the words out coherently.
Dazai pressed a kiss to Chuuya’s lips, and Chuuya thrust his tongue into Dazai’s mouth, tasting salt. Dazai pressed forward, like he wanted to devour Chuuya whole, and Chuuya returned the feeling. When they separated again, they were both struggling for air.
“I could do this all afternoon,” Dazai gasped.
Chuuya could do this his whole life, but he only responded, “I have time.”
Dazai stayed the entire night.
