As I lay there playing with my pussy, you, my brother walks in and takes pictures of me masturbating. I'm your sister, why would you do this? Is it because you want to jerk off to them or what? I can't believe you're blackmailing your own sister. I guess there is only one way to stop you from exploiting those pictures, perhaps I could allow you to fuck my tight little pussy.
