Jacking it for my step daughter Binky

You busted your step daughter for giving a guy a hand job. She can't help it, though. She likes making guys feel good. Please promise not to tell her step-mom on her. Please? Maybe if Binky shows you just what she was doing you can keep her secret. She wants to show off her technique and she quickly persuades you to start stroking your dick. The guys she usually jerks off have much smaller dicks than yours. 18-year-old Binky wants to show you her titties. They are perky and you briefly think about how much trouble you would be in if your wife walked in on you with your step daughter. Never mind - you just keep jerking it. Binky encourages you to jerk off faster so that she knows how much you want to cum for her. She really wants to put her hand on your cock, so she does so very quickly.
