Can I have some nsfw headcanons for sub au for kanato and Azusa please

(ц｀ω´ц*)

Kanato:

-Kanato is beyond needy, both sexually and when it comes to affection. For a long time, he’ll try to use sex as a means of controlling you, and even when that fails, he wants physical affection almost constantly. He’s a total brat, and will complain incessantly about anything that he claims not to like, and yet, throws even more of a fit if you try to stop. It helps his pride to pretend like he doesn’t like the more embarrassing things you do to him, so establishing a safe word from the beginning is essential, even if he claims not to need it. 

-He’s more than fine with your arrangement being a permanent thing. As in, if you want to use him while he’s asleep, he wouldn’t try to stop you. If you wanted to control what he eats and wears, he’d complain, but go along with it embarrassingly quickly. If you wanted to do things to him in near-public, he’d take pride in the fact that you’re so willing to claim him. His ideal situation is to be like your little doll, a possession to be owned and loved. There are a whole pile of issues to sort out with that, though, as his idea of a relationship is far from healthy, even when he’s not the one in control. 

Azusa:

-This one is pretty obvious, but Azusa lives for pain. Whatever you can do to him is fine, as long as it hurts. His healing means that he can take a lot more than a human can, and he’ll happily let you cut deep gashes into his skin, whip him bruised and bloody, choke him, or anything else that will let him feel how much you care. In his view, pain caused by you is a sign of love, and he can’t get enough of any way you can hurt him, be it in a sexual context or not.

-While Azusa does tend to be downright demanding when it comes to you hurting him, he’s far more concerned about your pleasure than his own. You could keep him from finishing for weeks, and as long as you were happy with it, the desperate agony would just make him all the more driven. As long as you’re paying attention to him, anything you do is welcome, and as long as he can feel the pain the signifies your love, it doesn’t matter what else you want from him. He’s one of the subs who claims to have no limits… and worryingly, he means it.
