The student thought it was some kind of art class, but I tell them it's not and that they must sit through the whole class or fail. Im wearing a thong and bra under my robe and then take off the robe. I'll show a close-up of the inside of my pussy, my boobs (nipple and underboob), my asshole, and my pretty face. Then the real imagination part starts, which will involve stuff the thong into my pussy, and then masturbating.
