Once a standard week rotation, every standard week rotation. Something happens, a suspension of the carefully ordered hierarchy and power dynamic on a Benduday night; no other night will do as routine is sacred.
20.05 hours, not a second later. That's when he arrives; straight from the bridge and no stops along the way. As pristine and well groomed as he started his charge at 08.00 hours that morning, there is not a single hair out of place or any hint of anticipation as he stalks the durasteel corridors towards your single-bedroom dwelling. He's far too disciplined for that, far too in tune with Imperial propriety to drop any hints but if he is going to bow to these biological urges, no matter how bare and basic they might be, he is going to do so on his own, disinterested terms. It is a case of body over mind for General Hux; in this instance and this instance only.
It would have suited him better to have found someone of a similar wavelength to himself, with a similar thought process. Someone who was not a slave to the bodily desires and only placated them on a semi-regular basis to prevent them building up and therefore, distracting from much more important things. Unfortunately for the General, no such person existed and it they did, he was yet to find them.
You were the next best thing. Quiet, demure and dedicated to the Order with no character of licentious behaviour (that your records and a thorough evaluation showed, anyway), you were the best of a bad lot; so to speak. They teased you, the other officers, for your meek disposition; some even called you boring and frigid.
If only they knew.
He had approached you matter-of-factly, in a business sort of way, once he had made a decision and chosen to act upon it. He had categorically stated that he did not find you attractive; not in the sense that your looks had been a deciding factor in selecting you, at least. He stipulated discretion; you could do that, no one spoke to you anyway.
No touching, no kissing, no talking, "equipment" would be provided by him and would be replenished by him when required. Contact would be absolutely minimal unless completely unavoidable and would be conducted through one specific mouse droid.
He didn't knock, not anymore. Rather, he allowed himself in, gave you a curt, greeting nod in the living area before seeing himself through to the bedroom. That was your cue.
Hux remained in the rigid envelopment of his uniform; to be in any other state would allow you a glimpse at a vulnerability that you did not deserve. He did not look up when he was joined. Said uniform, you had your suspicions, had been constructed with an illusion in mind; an illusion to suggest he was more solid and more filled out than he was in stark reality. Why else would he hide himself from you, the only person (that you knew of) that he engaged in something out of the ordinary with? Of course, it had no bearing on the arrangement. And it was just that: an arrangement.
