Sayaka Aoyama, 30 years old. A beautiful housewife working as a sales administrator at a plumbing fixtures manufacturer. Even after eight years of marriage, her elegant looks continue to draw attention from numerous male colleagues at work. Since joining the company as a newcomer ten years ago, she's had a history of building relationships, with salesmen constantly inviting her to lunch. The field salesmen were known to be energetic and physically strong, especially vigorous in bed. Even after marriage, her cheating habit never stopped—she continued enjoying sex with others behind her husband's back. After childbirth, her marital relationship dwindled, and Sayaka gradually lost affection for her husband. As she confesses, "I feel bad toward my husband... but I can't stop now," she's become a complete cock addict, openly exposing her desires and baring everything in front of the camera.
