Looking for a movie

It was the VERY first porn I saw..It was on the video 2000 system of videos!!

Set in a sex club, there were a series of short 'shows'..one was in a classroom I remember that much..

Think it was TABU, but not 100%..Over 25 years ago now

Any one help???

Are you sure about the spelling? I remember the Taboo series from around that time. IAFD shows the first one being from 1980.
