A work depicting the forbidden relationship between a beautiful girl and her younger sister. While there may be some issues with image quality and lighting, the erotic charm of Ayami Mamiya is enough to make it enjoyable. Her intense gaze and lascivious acting are very arousing. The stability of the play and the actress's expressive power are also praised. Full of highlights such as dimly lit masturbation scenes, making it a recommended work for those with a slightly masochistic inclination.
