Prompt: Kylo has taken it upon himself to go old-school chaste, to dedicate himself more completely to the dark side. However, he also starts up a sexual relationship with Hux, wherein he denies himself relief but takes Hux apart as a sort of orgasm proxy. He tells himself it's so he'll feel the frustration more keenly, but he knows he just wants him.

bonus
+ Hux knows about his "chastity" and it makes him crave Kylo more
+ Eggs Kylo on to fuck him, grind on him, let him stroke him off, presses his foot up against Kylo's dick while Kylo sucks him, etc.
+ Dirty underhanded tactics for your consideration: Hux begs Kylo to fuck him while Kylo fingers him, tells him he wants his cock so badly he's aching, even after he's come / grinding back while spooned together, Kylo jerking him off, goading him to hump against him / palming Kylo's cock whenever he thinks he can get away with it / showing off his impressive lack of gag reflex, sadly wasted on poor Ren
+ Kylo keeping his clothes on to help his control because goddamn
+ Hux is not normally particularly sexual or vocal, but this arrangement's really doing it for him
