Karma Rx is my slutty stepsister. My best friend is been dating her for quite sometimes but I keep seeing her fucking other dudes. I am tired of all this bullshit so its time to fix things around the house. After catching her once again masturbating I get Karma to suck my cock and I even fuck her hard all over the bedroom , but this time Im filming everything so if she ever says anything to anyone I can show the tape to all our friends.
