Kaho-chan works as an office lady. The salary of the company I am working for is low, and I can't live a satisfactory life no matter what I take, such as rent, living expenses, beauty expenses, entertainment, etc., and I decided to start dad katsu because I wanted to escape the current situation. - Although it is okay to meet her uncle with a light feeling, as time passes, her demands escalate, and she begins to wake up feeling pleasure despite her feelings that she thinks are useless. From panchira to masturbation shows, and even vaginal shot. - She surrenders herself to pleasure and finds her calling, and turns into a nymphomaniac.
