Faye "I Need You To Cum"

Faye is having some back problems so she has asked you to give her a lift to see the doctor, while she is in the room the doctor asks her to get into all kinds of positions and you quickly notice you can see up her skirt. Faye is your step-sister and you have always had the hots for her sop as soon as you see her pale pink thong you get an instant erection, when the doctor goes out of the room and Faye spots the bulge in your trousers she decides to help you get rid of it.
