A female college student attends a self-defense workshop to overcome trauma from past stalking experiences through counseling and training. Living in Nakano Ward, she participates in the sessions to increase her personal security awareness. During the workshop, she changes into athletic wear—wearing a thong with matching top and bottom training gear—and begins learning self-defense techniques under the instructor's guidance. As she practices responses to being grabbed by the arms or upper body, the instructor subjects her to sexual harassment. She is repeatedly assaulted—pushed down onto the mat, stripped of her clothing, and groped on the breasts. Further, her legs are forced open and she is fingered, stimulated with a vibrator and electric massager, then subjected to intercourse in missionary, doggy style, and side positions. The acts include creampie, deep throat, and arched-back convulsions culminating in orgasm, followed by additional creampie. Throughout this ordeal, the woman maintains a serious attitude toward learning, using the situation to practice responses when caught in sexual harassment and cruel treatment.
