Naughty Babysitter and My First Erection

Your step-stepmom and step-stepdad will be home soon. The house is a mess and the nanny is trying to clean up so your parents don't blame her for the mess. Suddenly, the nanny sits on your bed and asks a strange question "Have you ever seen a woman's pussy?". She seems to want to show you her and tell you something new that you have never seen or felt before.
