Seshaa is a very powerful, strong huntress. She hunts on a far away jungle planet, and dominates the native species that live there, both sentient and non sentient ones. She never has any problem showing her dominant nature, and others can do nothing but suffer. But one day, a young space pilot from another planet suffers an engine malfunction and crashes down on this world. Seshaa soons spots his or her sent, and starts the hunt. While the new arrival can't possibly fight back against such power, they are quite smart, and instead manage to evade the huntress, and injure her in many ways. They set traps, do hit and runs, enough to weaken her. But while Seshaa gets aroused by giving out pain, she also gets aroused when she's on the receiving end too, and this hunt proves to be very stimulating for her.
So for this RP I was thinking of playing a strong demon that has a weakness, the fact the hunt turns her on, and her new prey can use that fact to inflict all kind of pain and injuries to her. Anything is fair game sort of killing or completely restraining her. You can use contraptions hidden in the forest to break down her armor, you can make traps to catch her and force her to break an arm to get out, maybe you have a stun blaster that would electrocute her, which would just make her body even more horny, things like that. While you wouldn't be anywhere near strong enough to match her toe to toe, there's a lot that can be done still. The more extreme, the better.
