Celebrating her husband's promotion, Mariko (An) enjoys a happy life—until she's assaulted by her husband's senior colleague, Sakuragi, who comes to retrieve a forgotten item. Unable to confide in her husband, she is repeatedly raped by Sakuragi, gradually losing control of her mind and body to relentless sexual pleasure and deep humiliation. Forced to masturbate in front of a mirror, she becomes a victim of twisted games—her genitals toyed with in secret moments when delivery workers pass by. Bound in bondage, she is trained like a female dog, her voluptuous body completely dominated. This shocking narrative, supervised by Kozo Nagira, portrays a young, well-endowed wife being swallowed whole by raw desire. A Married Woman Sex Slave production by Orga under the Amor label.
