Kylo and Hux have a disagreement. As "punishment" (or just you know payback etc), Kylo makes Hux immobile with the force and proceeds to ride him. Hux is turned on but also frustrated he can't touch / do anything. Bonus if Kylo is a bit clumsy / didn't prep himself enough(because we all know he is one giant impatient child) and it's borderline uncomfortable tight for the both of them. C:
