When I went back to my parents' house to visit the grave, I happened to meet my teacher from my school days. We got talking and decided to drink at a bar. I got carried away and had a one-night stand... But the teacher liked bondage... Mei was tied up for the first time and woke up to an unknown pleasure. Unable to forget the pleasure of being tied up, Mei masturbates with self-bondage but is not satisfied... While her husband is away on a business trip, she goes on a two-day, one-night affair with her teacher.
