Finishing School (1976)
"She took a cram course in pleasure... where no homework was too big, too hard, or too wild!"
The minute Laura sees the Instructor looking at her long erotic legs she knows she has him where she wants him. This sight, in the front row, makes him so nervous he decides to work it off on the tennis court where he is met by a young eager coed who lures him to her apartment, where she is tutored in some social studies. Even a class orgy with plenty of her hot young friends and a lesbian encounter can't get her mind off the instructor. Laura watches as one of the girls from her class enjoys a menage-a-trois. At last Laura and the instructor are alone in his office where she gets what she wants.
