Three stories of schoolgirls awakening to the world of diapers. act 1: the story of yuma-chan, who has frequent urination and bedwetting habits, and her overprotective stepmother. they try out different types of disposable diapers together, checking them at night and changing them while she sleeps. a tale of mother and daughter bonded by diapers. act 2: high school student chie, who can't go without diapers due to her incontinence, becomes increasingly infantilized. years later, chie is completely babyfied, having her diaper changed in a baby room. act 3: a black-haired beauty, suzu, enjoys playing with various disposable diapers alone. her day starts with removing her soiled diaper in the morning, putting on a tape-style diaper and cover before heading out. but she ends up peeing herself outside, her small diaper leaking urine, and masturbating while excited by her wet diaper. a compilation of suzu's solo diaper play.
