50-year-old Kotomi Sahara works as a hostess at a coffee shop and lives her daily life. Kotomi is popular, and many customers care deeply for her. Unaware that her pregnancy resulted from an affair, she gave birth and became a single mother. Her path into adult videos began by chance. On the shoot day, the scheduled actress suddenly canceled, and Kotomi, who happened to be present, stepped in as a replacement. As a result, she ended up performing with two male actors and made her AV debut.
