ACZ-135 Amu-chan is staying at her brother's house, and she consults with her brother's wife about how to keep her beloved brother from finding out about her peeing habit... - Chiharu Nogi

Amu-chan is staying the night at her older brother's house. She loves her older brother and doesn't want him to know that she still has frequent urination and wets herself. So she decides to ask her brother's wife, Chiharu, for advice. After much deliberation, the kind Chiharu buys a lot of disposable diapers. She suggests a plan for Amu to wear diapers during her stay. Chiharu takes the disposable diaper plan very seriously (and is completely naive). This is a heartwarming and romantic diaper drama.
