dazai crouching at chuuya's doorway begging to be let inside after spending his first night of rut with an omega and was not satisfied because he needs a knot. HE NEEDS CHUUYA'S KNOT OR HE'LL DIE was what he kept saying until chuuya finally let him in 20 minutes later. Dazai launched himself onto chuuya without warning, grinding and desperate to chase his release but its not working. "alpha please!! please knot me please please please please please!!" borderline screaming and crying. chuuya hissed when he felt an eager hand gripping his front seam, a moaning mess when dazai starts to nib at his sensitive neck. "FUCK, DAZAI STOP!" its not a rejection, he is too aroused and afraid that he would cum way too early with the way dazai is still fondling and grinding on him. 

30 minutes later, all of chuuya's neighbour (his mafia subordinate) can only hear dazai's screaming in pleasure as chuuya keep ramming into his puffy and oversensitive hole not caring if he's already knotted because thats what dazai desserve. dazai can take more and chuuya know he can. (they knotted together but chuuya will not stop any sonner)
