This was such a good prompt, thank you OP, I hope I've done it justice.
The day Hux does it is the day he finally lets Kylo come in with him.
Not that he hadn't been feeding him bits of information over the past few weeks. He hasn't kept him completely in the dark. That would have been cruel.
He'd just not told him where. It wouldn't have done for him to be interrupted during something he'd laboured over so intensively - not prematurely, at least.
It hadn't been easy, despite the power he holds as general, to fake a visiting diplomat's death. (Faulty airlock, oh dear.) He'd even gone to the memorial service and signed the book of condolences - and not with "fuck you" as Ren had suggested - before it was given to his grieving widow. She'd not much to grieve over, both figuratively and literally. The beauty of blaming an airlock used to eject trash for a death is that nobody expects a body.)
But now. Now the time to show him is right and it feels glorious. Whilst some would champion the peace that forgiveness brings, Hux wants to laugh and vouch for vengeance instead. Years of bitterness have culminated in this, him, looming over Kylo on the immaculate (yet infrequently used) storage room floor, smearing his mouth red with blood as his victim enters the gurgling stage of dying. Funny what having his throat torn out will do to a man.
"Victim". Hux wants to laugh cruelly, so he does. Kylo looks up at him, wide-eyed. Wanting. Impressed. It's a potent mix, and he leans down again and nips at his throat, mirroring how he'd finally struck the fatal blow. Kylo makes a keening sound and rubs their hips together, shuddering hard enough that Hux feels it when he sucks a mark under his jaw.
The silence when he pulls back to look at it is punctuated by another wet choking sound.
"I can't believe you finally let me see-" Kylo breathes, and kisses his cheekbone, his jaw, his neck. "I'd no idea you could be so-"
"Cruel?" Hux sneers, and takes his wrists in his hands to pin them either side of his head. He's removed his gloves but not in time - the blood had already soaked through. His fingetips are red where they hold Kylo's own immobile.
Kylo shakes his head.
"Visceral." he breathes, awed.
Hux rewards him with a kiss. He can still taste blood in his mouth, in the cracks of his teeth. Kylo grinds against his stomach and Hux feels a stab of arousal so sharp it's like it's him that's had his stomach (and lung, and eye, and - he could go on) punctured. He wants to get off quick and dirty right here on the floor, wants to make Ren scream as loud as he had the man strapped to the table, if for a completely different reason.
In the time it's taken him to think, Kylo has wriggled free.
He pauses.
"Tell me, Ren, how long does it take a man to die?"
Ren grins, and it's full of savage glee.
"I'd say he's half an hour left in him. If that." he says, and he's working on Hux's belt.
"Well then." Hux replies, grabbing Kylo's thigh and pulling it to hook around his waist. "We haven't a moment to lose."
FILL - Visceral [tw for inferred rape, torture, murder, general fucked upness]
