Test her Commitment

Her words are one thing, but her actions must speak loud and clear. To submit is not enough. She has to debase herself, surrender completely. You point at the first step leading up to your throne and speak with a voice that allows no defiance, loud and clear: "Kneel."

It is a command that could have shattered armies, and while her knees buckle, she hesitates. The fight is still there as she grits her teeth, taking a few steps forward. This is why she was always worth your attention. Had you come upon each other a few centuries earlier, things might have turned out different. Perhaps, she would have stood by your side, general of your armies. These days you won't have use for such a position anymore. Not in the same way.

She comes so close, you can smell the sweat and grime of her body, the constant stench of perfect battle upon her. She's not dirty in any way, just always with a thin sheen of action upon her skin. Your eyes lock with hers. You both have to chuckle at the familiarity of the moment. A dance of power, only this time it is not blades and muscles that wrestle each other, nor ingenuity of magic and machine.
"You must have waited a long time for this." She mutters under her breath.

"Years." You admit, lounging in the width of your throne like a cat about to be served its favourite meal. Your arousal stirs under your armor. There's nothing like exercising your power upon the weakness of mortals.

She succumbs, slowly lowering herself to the floor, but she never breaks eye contact with you. She's not giving up all her dignity - Her stare spits fire.

Clearly this is not enough, not with how much she's asking - A whole town put under your personal protection? Kings have died for less.
