Point de fuite (1987)

A teacher gives a very sexy lesson on perspectives in the short-film Point de fuite (1987).  A professor (Catherine Aymerie) arrives late to her class to discover that her students have all stripped completely nude and are nonchalantly waiting her instruction. Instead of acknowledging their bizarre behavior, she starts her lesson plan as usual then strips off her own clothes to lecture fully nude. While her back is turned, the students slowly put their clothes back on, leaving her starkly out of place when a knock comes at the classroom door. There are naked females students in the class but the best au natural performance is from the teacher, Catherine Aymerie, who reveals full funbags and fluffy muff when she decides if you cant beat 'em, join them. Meanwhile we’ll be beating it!
