Frisky stepsister found on Tinder, demands payment for silence

My stepsister, a self-proclaimed slut, caught me on Tinder. She\'s blackmailing me, threatening to expose our secret if I don\'t pay her. I\'m gay, but she doesn\'t care. She wants money, and I\'m forced to comply. This isn\'t the first time she\'s done this, but it\'s getting old.
