You don't want sad rape anyway, that's depressing. You want her to rape you out or anger or jealousy.
Better yet convince her to use sex as a way to work out her frustrations non-violently. You can be like her stressball. Any time she feels her anger building up, she can just grab you, regardless of what you're doing at the time, and go to town on you until she feels better.
And she's got 6000 years of anger to work through.
