I can’t believe I walked in on you jerking off. Step-Mom sent me to tell you to fold your laundry and here you are watching porn while you stroke your cock. You know Step-Mom doesn’t like you watching those dirty movies. Is that the way you jerk off, it doesn’t even look like you’re doing it right. Here let me help you get all the cum out so you’re not feel all that pressure in your hard cock. It’s okay I’m only your step-sister and I am sure we aren’t the only step-siblings that do this. Don’t worry I won’t tell Step-Mom either it will be our little secret!
