In the heart of Spain, Claudia Bavel, a fiery Spanish teacher, can't resist the thrill of exhibitionism. She hops into a taxi with Kristof Cale, her eager student, and gives him an eyeful of her perky, bouncing breasts as she straddles him in the backseat. The driver's eyes widen in the rearview mirror, catching glimpses of Claudia's ripe cleavage as she unbuttons her blouse, exposing her hard nipples to the cool Spanish air.
