Imagine sitting on the couch watching your Step-sister do her toes in a white bathrobe. It falls open but she does not notice as she is focused on redoing her toes and pays no attention to you watching her. You can feel the bulge in your pants start to grow, you know you should not be looking but you can't help it. Her tight body posed for you to see, and her cute little toes and soles in plain view.
