My stepsister helped me cum

You can call me whatever you want, even throw piss rags at me, but I am firmly convinced: when I masturbate, it is the holy of holies, a personal and intimate matter. Bursting into the room at such moments is a sure way to get hit on the head. However, my busty stepsister, it seems, does not agree with this: she enters without knocking and strolls around my room as if it were Nevsky Prospect! And when she sees what my hand is doing, she immediately gets involved in the process - first she rubs my penis with her tits, and then she jumps on top. All this, of course, is complete debauchery ... but, damn, how pleasant!
