The dirty German teacher

In Los Angeles I visited a friend who had problems with his German girlfriend because he doesn't speak German. Of course I am happy to help and offered myself as a teacher and taught him the "important" German vocabulary directly. Which could that be ...? It is soooo sexy when Americans speak German. So it wasn't long before I put the newly learned terms into practice with him. From "kissing" to "blowing" and "fucking" to "sperm" ... all vocabulary learned memorably. I really should be a teacher. Would you let me teach you?
