If one gives out points for minimalism, then the Brit Porn feature "F*ck the Teacher" has some value, but I would round off its merits at zero.
The uncredited filmmakers have the temerity to present five virtually identical vignettes shot on the same set, an undecorated one with a male student and female teacher having a dull conversation and then f*cking. There's no school, the actors are too old for their roles and the actresses are mainly unimpressive. Exception is Franki, always alluring with her Barbara Steele look plus a hot body.
Porn has a sort-of- genre called College, which I suppose is to hint at younger people involved, but this one doesn't qualify.
