I can’t believe your grounded because you got caught masturbating. Our parents are such prudes. You don’t need to be embarrassed. It’s a natural thing. Even I do it. If our parents won’t show you that it’s ok to explore and enjoy your body, your step-sister will. If you stroke your dick, I’ll play with my pussy.... Haha or I’ll just trick you into getting your dick out in front of me. I bet you’ve imagined stroking your hard cock to your step-sister. I always knew you were the perv of the family.
