Misaki (pseudonym) is a college student being trained by Morishima, the landlord of her apartment, following a certain incident. Within her daily routine, she gradually comes under Morishima's control. This work captures intimate training sessions, including anal stimulation with a vibrator, achieving orgasm through cervical (porchia) stimulation, and creampie sex scenes. It carefully depicts how her body and mind transform over time. A profound fusion of deep emotion and physical pleasure, this film explores the pleasure derived through training and the blurred boundary between domination and submission.
