Hoshino Miyu plays an intelligent female teacher who is immensely popular with her students. However, after school, in an empty classroom, she throws off the mask of "teacher" and begins her lewd practical training. Her skirt is roughly lifted up on the desk, and her body throbs with a sense of immorality as her student's cock strikes her. Only uncensored footage can capture her intellectual expression dramatically disintegrating with pleasure, as she drools and climaxes. The rawness of the process as the sanctuary of education is highlighted. A supremely immoral drama in which the instructor succumbs and exposes herself to the climax of a female.
