"Dazai! Where on earth were you at that was so much more important than your work!?" Kunikida screamed as Dazai, Atsushi, and Ranpo entered the office.

"Kunikida~" he whines as he slumps into his chair. "Could you please stop yelling at me, It's already been such a long day~"

"Oh, Dazai was with me and Ranpo," Atsushi tells Kunikida.

"So that's where you were all day," said a ginger man who happened to be walking by.

Atsushi turned to the man, having to look slightly down to meet him in the eyes.

"Oh, you must be the new member. I'm Chuuya Nakahara, your Atsushi, correct?"

"Oh, um- yes! I'm Atsushi Nakajima, sir."

"Osamu told me all about you after he had met you. I'm sorry I've been so busy myself that I haven't had the time to meet you." Chuuya gives him a hearty smile, proceeding to his desk next to Dazai's.

"Chuuya~ when can we go home?" Dazai asks, rolling around in his chair.

"Just give me a minute to pack all my things and we'll leave."

"Oh, you two live together?" Atsushi asks, sitting at his desk across from Chuuya.

"Of course we do Atsushi!" Dazai held up his hand, showing off the silver band around it. "We've been married for almost four years now!"

Atsushi's brain short-circuited for a moment before coming back to reality. "Wait- Dazai you're married?"

"It may not seem like he is based on all the women he's flirted with, but yes, I'm sadly married to this mackerel," Chuuya says as he slowly gets up after finishing putting everything in his satchel.

"Chuuya! You're so mean!"

"Well maybe if you stopped flirting with women, then I'd be a lot nicer."

The two argued on the way to the door, before exiting to make their way to their apartment.

"So... based on my knowledge they've been married since.. 18?" Atsushi was a bit surprised thinking of it now. He was already that age, and he could never think of getting married to anyone.

As soon as they entered the apartment, slamming the door shut, Dazai was on top of Chuuya.

"God at least gives me a minute," Chuuya laughed as he managed to throw his bag to the other side of the room.

"I can't Chuuya, I haven't seen you all day." Dazai breathed out, beginning to take off Chuuya's clothes.

Following along, the ginger helped with his clothes, after helping the brunette with his button-up shirt.

Once fully naked, Chuuya was flipped over on the bed, his ass up in the air for Dazai to enjoy.

Without warning, the brunette spread the other cheeks, placing his tongue flat against his hole.

"Osamu!" Chuuya flinched, pushing against the wet mass of his tongue.

Continuing, he licked the rim before dipping his tongue in, earning a pleased moan from the other.

"You're quite vocal today, love," Dazai smirks, adding emphasis to the nickname.

Chuuya responded with a moan, digging his face into the futon as his face turned red.

"God dammit- Shitty Dazai..."

"You're a Dazai too y'know," Osamu smirks while pulling away from the other, earning a groan.

"Oh god, don't remind me."

"Chibi!"

After their small argument, Chuuya turns around and pushes Dazai flat on his back while sitting on his lap.

Chuuya strips Dazai of his remaining clothes before grinding down on him. The other's cock between the gingers ass cheeks.

Dazai moaned as he grabbed Chuuya's hips, "God this is hot."

Chuuya soon slowed down, reaching over to grab the lube.

"I need you inside me, right now."

"Be my guest," Dazai replied while he looked Chuuya straight in the eyes as he applied the lube to Dazai's cock.

He thumbed the tip before taking the length into his palm, gliding his hand along the length.

Grabbing the ginger's hand, Dazai closed his eyes as he held back a groan. "That's enough Chibi..."

Chuuya released his hand, angling his hole above the length before taking almost half of it in one go.

"Did Chuuya play with himself this morning? I thought you seemed a bit looser."

Chuuya rolled his eyes before rolling his hips, slowing inching himself inch by inch before reaching the hilt.

Moaning in unison, Chuuya leaned forward, letting Dazai take his lips into a heated kiss.

Chuuya circled his hips as Dazai's tongue entered his mouth, trying to get down his throat.

"Chibi is more fired up than usual, and I love it," Dazai gave him a toothy smile as he leaned up and gave the redhead another kiss.

In response Chuuya placed both of his hands on either side of Dazai, slowly lifting himself till the tip was in. Before the brunette could utter another word, Chuuya slammed his hips down, a loud slap echoing throughout the room.

"Ah- oh god Osamu-!" Chuuya moaned as his eyes rolled into the back of his head.

"Jesus Chuuya- you're gonna hurt yourself..."

Chuuya began bouncing on Dazai's cock, lifting himself halfway before slamming down. Occasionally pulling the same stunt as before.

"Ah- so good... Oh god!" Dazai's brain suddenly short-circuited at hearing the other's sudden cry of pleasure.

"Oh, ~ Did I hit Chibi's prostate?" Smirking he held onto Chuuya's hips and began moving them as he thrusts up into him.

"God, god, ah- Osamu! Please, please I need to cum!"

"I don't know... has Chibi been good?"

"Yes, yes, yes!"

Dazai grabbed Chuuya's collar, bringing him close enough for their foreheads to touch. "Then come."

His back arched, sobbing as a moan slipped from his lips before coming across Dazai's stomach.

After a few thrusts up into that tight heat, Dazai came inside the other.

While Dazai slipped out of him, Chuuya flopped next to the brunette, exhausted out of his mind.

Dazai turned to face him, placing a hand on the other cheek. "I love you Chuuya." He kissed the ginger as he wrapped his arms around his waist.

"Mmm- I feel filthy. I'm gonna take a shower." Chuuya crawled out of his embrace, standing up and walking to their shared bathroom.

"Chuuya! You didn't say 'I love you' back!"

Dazai followed him into the shower, resulting in an angry and yelling Chuuya screaming his husbands name once again.

The next morning Atsushi arrived early to work, not wanting to show up late already after just starting the job.

Dazai and Chuuya arrived ten minutes after him. One thing in particular he noticed, was Chuuya-sans obvious limp.

"Chuuya-San, are you feeling alright? You're limping pretty badly..."

Chuuya turned beet red in reply, earning a chuckle from Dazai.
