Foot Assassin
Back Story: To capture you I’ve discovered your foot fetish and with the help of evil scientists, devised a serum that would render you oblivious whenever exposed to the one thing you couldn’t resist: My feet. I’ve slipped you the serum, seduced you into worshipping your feet… you fade out, and I capture you. Basically, My feet are your Kryptonite now, even though you’re still wildly turned on by them.
You’re coming to and I explain to you how I’ve caught you, how you’ll never escape this compound and tease/drain you with my feet. You become weaker and weaker as I coerce you to sniff my feet in your face. Finally you begin to drift off into oblivion as I shove a sock gag into your mouth, you hear me tell me henchmen to lock you back up.
