A series where girls who used to wear bloomers as students confess the erotic acts they did back then. This time, we have Mayu, a beautiful girl with big breasts that are visible even through her gym clothes. She wore bloomers in class until she was in the third grade of elementary school, and even after bloomers were abolished, she continued to wear them as an inner layer for her school uniform skirt until high school. She gets immersed in bloomer play as she talks about the erotic acts she secretly did while wearing them.
