The movie is something I saw sometime 1996-1997 on cable tv. The movie is about a teenage girl who paints or studies fine arts and lives by herself. She is a bit sexual. She then begins to have an affair with her older and married arts/painting instructor/teacher which sees her and paints her in the nude afterwhich they have sex… It was surely an english movie and colored. There were also scenes like an asian boardmate that played the cello and a scene where the girl and the teacher make out or something in the kitchen while the teacher hosts a friendly dinner at his house for the girl.
