Jinx

She is your step sister. You and your friends go to a strip club one night. As you take a seat by the stage, the DJ announces, “Next dancer on stage is the naughty Jinx. The lights are in your eyes and you can’t see her face yet, only her fantastic body. Finally, she gets closer and you realize, Jinx is actually your stepsister Jin. She sees you and freezes. She covers her breasts and leaves the stage.
