Late at night in the office, I—the manager—reviewed the security-camera logs to investigate an inventory discrepancy. What I found was the unbelievable secret side of serious H-cup part-time housewife Fumika Kashiwagi. Complainers, cocky part-timers, visiting vendors… Ignoring her manager, she wore a look that suggested she did not entirely mind as she offered her holes to all kinds of men, becoming a ¥1,050-an-hour human toilet.
