Kylo has an insatiable need to be dominated and pushed to his limits. Hux is more than happy to oblige him. They've fallen into a routine where Kylo finds some secret to keep, and Hux ties him up and "interrogates" him to get it out of him.

Except pain doesn't really work all that well. Kylo's too immune to it. So one night, Hux explores new ways of breaking him. Gentler ways.

I want to see Hux overwhelm Kylo with teasing, light touches, bringing him to the edge and then not letting him fall over it. Over and over again. Turns out Kylo has no real defense against this kind of assault.

+ Kylo is blindfolded

++ Tickling is involved
