Custom video. Your step-sister barges into you room while you're masturbating. Teasingly she tells you she knows what you were doing and who you were thinking about. Your own step-mother, you try to argue but she assures you she understands because she is hot. And it's only natural. She offers to give you a handjob to finish what you started and you can pretend it's your step-mom. She dirty talks, encouraging your lust for your own step-mom. You bust at the thought of her cumming on your cock... She then turns to the door and says "see step-mom, I told you he is as horny for you as you are for him"...
