A middle-aged literature teacher who favors pure literary works encounters a student, Lala, who takes interest in the novel he is reading. The protagonist of the novel is a man with masochistic tendencies, and Lala becomes deeply intrigued by this character, eventually realizing that the teacher himself is also an M-man. Knowing this, Lala begins seducing him, exploiting her position as a student to gradually dominate and control him. Unable to resist Lala's lewd torment, the masochistic teacher is forced into days of having his hardened cock jerked off. With a mischievous, devilish attitude, Lala teases and manipulates him, questioning him with lines like "Don't you actually enjoy being mistreated by women?" as she pushes him toward ever-greater pleasures.
