Female college student shares a room with office worker - Sweet cohabitation with slutty younger sisters COGM-083

Common overseas, and increasingly so in Japan. A few months ago, in the shared apartment I started living in with relatives and friends, a junior from university, Koharu, suddenly moved in. She was gentle and quiet, always smiling, and decided to live with the three of us after saying "she looks interesting." Two guys living with one girl—don't they have any concept of chastity? Sure enough, everyone developed a relationship with her, and now they all get along fairly well! A life of endless sex.
