Kaidou/King Headcanons
they’re into pretty extreme bdsm
King will do just about anything Kaidou tells him to, or at least he’ll try - Kaidou enjoys giving him borderline impossible tasks and watching him struggle to complete them so he won’t end up disobeying orders
if he does fail, harsh punishment awaits, often dished out with a whip
Kaidou is super possessive, he loves marking King up with bites, loves being the only one allowed to see King’s face and speak his real name, loves putting a collar on him
King is what one would call a monsterfucker, he loves when Kaidou shifts into his hybrid form, loves feeling the scales and having the claws dig into his skin
King absolutely has a praise kink, he can come just from being told ‘good job’ by Kaidou
both of them like it rough and enjoy displays of power and a little hurt - sure Kaidou is in charge, but if he’s taking King from behind and getting burned by the flames on his back, great
the one part of King that Kaidou will always treat gently are his wings. King preens so beautifully when Kaidou runs his hands over the soft feathers, it’s a wonderful sight he doesn’t want to ruin
Kaidou usually uses ‘King’ - it’s the name he’s given him, showing both his respect and his ownership, plus it can easily be used to mock when King is kneeling in front of Kaidou, bloody and messy and begging for Kaidou to hurt him some more
but in intimate, emotional moments, often in the afterglow, Kaidou will use ‘Alber’, and the rarity of it gives it even more weight and meaning
