Ms. Usuhira, who has been married for four years, is currently a teacher at an English conversation school. The couple both work, and they would occasionally enjoy their days off together. However, about half a year ago, they both became busy, and even their days off were spent separately. Around that time, she was confessed to by a student and, feeling lonely, ended up having a physical relationship with him just once. After crossing the line, she became captivated by the world of taboo and couldn't stop.
