You’ve got power armor, yes? Any of your foes likewise equipped? Because if so, it opens up the possibility of trapping them. Disable the batteries of a woman’s armor and she’s stuck in a form-fitting metal shell too heavy for her to move with mere muscle power. Then rip off the torso armor, leaving her limbs stuck but exposing her breasts and crotch and have your way while she futilely squirms in anger and fear. Then finish off by setting the armor on fire so she either roasts alive in it like a Brazen Bull or is blown to smithereens when the ammunition cooks off.

Like a sexier, gorier version of this.

Victim being a bratty korean woman optimal.
