Kylo Ren is like a wildfire; destructive, brutal, burning, untameable. Hux has witnessed his power and complete lack of self control for long enough to assume that Kylo would be fiery in bed too. He's is entirely prepared for that by the time he convinces Kylo to come to his quarters with him.

Except that's not what Hux gets. Instead, Kylo is awkward and unsure and clearly has no idea what he's doing. It doesn't help that he seems to be more inclined to fumbling and sloppy affection than bitey scratchy hatesex.

Hux is now stuck dealing with this. Whether Hux ends up enjoying himself anyways, feelings emerge, or it's just bad sex - I'm good with any direction this goes!
