At 20 years old, Miwa had been married for one year and three months, but she could no longer tolerate her husband secretly watching AVs. Her frustration and rebellious feelings toward his behavior led her to respond to a gravure idol AV actress recruitment ad. Although she once chose infidelity, it happened by chance when she was picked up during an argument with her husband. Lying across a desk, she became aroused knowing she was being watched and indulged in masturbation. Her pussy made squishy sounds as her fingers played with it, intensifying her erotic pleasure. Later, she experienced intimate filming without protection in a hotel, which became a turning point in discovering a new side of herself.
