Since the day you first met, Anna Swix, your step-sister, has been persistently pursuing your manhood. You've been restrained up to this point, but remember that you're only human, and your balls are beginning to get bluer than a BB King solo. But Anna is aware of you and knows you'll break. She starts making fun of you whenever she has the chance when your parents are away from home. First its nudity at the breakfast table, then pussy flashing in the car, and finally she gets physical. She's been fucking with you for far too long now, it's time to fuck her back.
