This role-play is performed by adults. Ai, a adult schoolgirl role, is molested by the same old man on the train almost every day. Even if I wanted to change my morning commute to school, there weren't many trains in the countryside, so I had to put up with being molested by the same old man on the same train every time. One day, her mother was introduced to someone she wanted to remarry, but it turned out to be a molester old man...When she thought about her mother, the kind-hearted girl couldn't resist, and began to be molested not only on the train but also at home.
