I Have been a very naughty schoolgirl and have fallen behind on my sex education, so I have my toy and need to give myself a good examination with it. I need to learn how deep my pussy is and how easily the toy moves around inside my very slippery hole. Then the most important part of my exam is to see how long it takes until I can orgasm! You will have to judge how well I do and let me know how good a grade you will give me?
