PPPE-082 Living with the Indifferent Neighbor with Big Breasts and a Tsundere Attitude for One Week: Yumi Shion

My neighbor's sister, Shion, has always been unfriendly, cold, and scary, so I'm not good at it... However, my parents are on good terms, and they decided to take care of me for a week while my parents went on a trip! Contrary to her blunt attitude, this older sister spoils me for some reason and comes to me as a slut! Watching my AV together, calling me to the SM club where I work part-time... and suddenly I notice. Sister, are you really talking about me...? Cohabitation life with a tsundere big sister to experience completely subjectively!
