Summary
Even after four months, Atsushi never really felt like he had ‘truly’ kissed Dazai.
Yes, they had kissed many times before. Forehead kisses, kisses on the cheek, and kisses on the mouth. But all those kisses were initiated by Dazai. Every one of them.
But that was about to change.

Summary
“Dazai hasn’t said a word since the ability activated.”
Chuuya’s blood ran cold. He returned his gaze to the miniature Dazai, and felt his chest clench.
Even though he had to be terrified, Dazai sat stiffly on Naomi’s lap. His face showed no fear, just a blank stare that was all too familiar to Chuuya. He looked like a lifeless doll with no agency of its own.
“Dazai, do you know who I am?” Chuuya asked, keeping his voice even.
OR Chuuya gets hit by an ability, turning Dazai into a baby & leaving Chuuya to take care of him

Despite having dated multiple men in the past, Yosano still hasn't been with a man who could make her feel good, much less actually make her finish without her faking it - until she met Dazai.

Summary
“Taking me so well,” Dazai praises her, pushing the pad of his thumb onto her tongue, collecting her saliva onto it. “So eager to have my knot inside you.”
Every word drips with something sweet and dark—like it’s been dipped in dark chocolate, filled with the very things that make Chuuya’s eyes roll back and her orgasm that much closer to combusting.
Or: a fic where Dazai fucks Chuuya with his knot.

Except Ranpo.And probably Mori. Unfortunately.
When an undercover mission forces them to pose as a wealthy married couple at a high-class mafia party, things spiral out of control almost immediately.

HAPPY DAZATSU EXCHANGE DAY 2026, YOU ALL!
——————————————
Atsushi is in for a ride this time. Dazai has certainly something planned for him, hopefully they finish before lunch is done. Knowing Dazai, probably not!
“Atsushi-kun!” Yosano slapped the desk, making Atsushi flinch and stare wide eyed at her. She narrowed her eyes when the boy shivered and flushed harder, panting. “What’s gotten you so spacy, hm? I have been calling your name a few times already.”
“S- Sorr- eegn!” Atsushi had to bite his lip when he felt a hand grab his cock, squeezing it before letting go again. “D- Did you sa-hngy somet- hinngg?”

Summary
If looks could kill, then the ginger could be easily dead by now. The brunette looking at him with half lidded eyes, his hair all messed up, bandages loosened exposing the taller one’s skin, the unbuttoned dress shirt revealing his bare chest, his unbuckled belt that hangs around his waistline, and his pants zipped open. Chuuya was not aware that he was eyeing his lover way too much to the point that he was mouth opened and drooling from this sight.

Summary
Dazai has ended up in strange situations before.
In fact, it was almost a way of life at this point, every other weekend getting kidnapped by some organisation, or getting himself in trouble in other ways– Since joining the Agency, it has almost become a slight hobby of his, to test what kind of uncomfortable situation he can land himself in, if only to see the way it makes his partner's blood vessels pop. Perhaps it was cruel, it was most certainly dangerous, but never once has Dazai doubted himself, let alone regret a time he has let himself be taken.
As his body is pinned to the table, he can’t say his resolve is shaken at all.
-
Forced to tackle a strange organization with the ability infused science to effect the body on the genetic level, Dazai finds himself in the cross-fire (self inflicted, of course) with some rather... unexpected side-effects. -

Summary
Dazai has always had an issue with sleep; however, ever since he's been with Chuuya, his sleep schedule has improved significantly.
And it's because of that, some mornings, Chuuya likes to wake Dazai up in the most blissful way possible until his fiancé is panting and whining for more. Dazai deserves to be treated as such anyway, doesn't he?
