A current piano instructor at a music college, who has had various erotic experiences through an affair with a professor, is summoned to his house for filming. Having previously been recorded masturbating and having sex in front of others, she became addicted to the pleasure. Now, she voluntarily participates in filming, moaning passionately while shaking her B96 chest—captivating footage of a woman discovered by the professor.
