Aimi is caught in a twisted, taboo relationship with her stepfather, yet at school she plays the role of a lustful female teacher who helps students relieve their sexual frustrations. Maintaining an intellectual, almost saintly demeanor, she secretly craves the feel of rough rope, her body betraying her composure as she becomes soaked with shame and arousal during bondage sessions. Her beauty and intelligence captivate her students, while Aimi herself is tormented by deeply painful emotions—such as when she thinks, "I'll suck you off, teacher,"—losing herself in desire and submission.
