First, the story plotline listed is wrong. (They probably didn't actually watch this movie!) It was not the husband that disciplines or teaches her. It is some blackmailers without the husband's knowledge.
Interesting story from Oniroku Dan. The story & script stand on their own. There is of course the prerequisite nudity, softcore sex & bondage scenes. Some but not all are erotic. Nothing too explicit on-screen. I would call them almost artistic at times.
The acting is good to very good. Playing the lead quite well is Miki Takakura, one of Nikkatsu's SM Queens. She later went on to some mainstream films and in her 50's a few adult videos. Kaori Asô is excellent & has a major role. She went in a number Nikkatsu Roman Porno movies
Not a complicated story and some basic elements we have seen before. It is well put together here which makes it entertaining even in the ending. Worth watching.
