Teaching Zoey Foxx to play the skin flute

Your neighbor Zoey is your best guitar student, but she has some bad news. Now that she is 18, her parents will no longer pay for guitar lessons, but Zoey still wants to continue with lessons. She could wash your car or clean for you, but she has something slightly more unusual in mind. Do you think that there is something that this cute 18-year-old girl can provide for you in exchange for guitar lessons? Oh, yes, there is definitely something. Zoey asks you to put your hand on your shaft and stroke it "nice and easy" as she stands up and removes her dress.
