My Dad is such a dick to me, he knows I am going through my hormones and I like to jerk off, he never knocks on my door and is always catching me jacking it. I finally got grounded, he treats my step-sister Kylie like a princess, she gets to do whatever she wants. Of course, all she wants to do is study and be a nerd, the second my Dad leaves I creep into her room. If I can’t use my laptop to jack off with I’ll use my step-sister instead. At first, Kylie is grossed out but I can tell this nerd has a freaky side. My step-sister lets me fuck her then cum all over her pretty face.
