My parents remarried, and now I have a cute, easily persuaded, and extremely shy step-sister! She goes braless at home, so she accepts the sexual harassment of having her protruding nipples played with every day! Even though she hates it, her nipples are constantly played with, both through her clothes and directly, and before she knows it, she's been trained to be an ultra-sensitive, premature-ejaculating girl! She's so sensitive she drools, and she's finally transformed into a slutty girl who begs to be touched! I'm living a life of non-stop sex with my step-sister, who climaxes in a vulgar way!
