Banging taut-poon stepsis

How do I penalize my legitimate-yr-senior stepsister for being mean to me, lounging to our parents and cuckold on her bf? Hmm, now that I caught her sneaking back into the palace at 8 a.m. when she wasn't even permitted to go to a soiree I can do anything I want, even ravage this bi-atch right in the garden. Okay, we nearly got caught there, but I got my messy fantasy fulfilled a few days afterward and still screwed this biotch so supreme. Damn, her cunt is taut as plow!
