Hux has a professional career in tech or finance, some button-down office job that leaves him staring at screens constantly. With his evenings and weekends, however, he rents a suite attached to the fetish bar The First Order and bills himself as the General. He charges exquisite rates, because part of his sense of control is that he's worth enough to be paid handsomely. He's incredibly dispassionate and professional with his clients, refusing to kiss or penetrate his subs in any way, but has a knack for putting them into precisely the headspace they crave.

I was imagining Kylux for this, but I'd be very, very interested in some other possibilities. Also very open to tables turning, Hux getting dominated himself, losing all professional boundaries and either initiating sex during a scene or interacting with a client outside of the constraints of their professional relationship.

+ Huge bonus for someone that he knows in his day job discovering his secret life and pursuing him into it.
