How do I punish my 18-year-old stepsister for being mean to me, lounging to our parents and cheating on her boyfriend? Hmm, now that I caught her slinking back into the house at 8 a.m. when she wasn't even allowed to go to a party I can do anything I want, even fuck this tart right in the garden. Okay, we almost got caught there, but I got my dirty desire fulfilled a few days later and still fucked this bi-atch so good. Damn, her vulva is taut as fuck!
