PPPD-837 Living together for a week with the cold, big-breasted neighbor: Matsuri Kiriya

My neighbor's Matsuri sister has always been cold and cold, so I'm not good at it... However, my parents are on good terms, and my parents will take care of me for a week while I go on a trip! Contrary to my blunt attitude, my sister will mess with me if there is a chance! Getting drunk and coming to a slut, or forced to co-sleep...! And suddenly I realize Sister, are you really talking about me...? Cohabitation life with a huge breasted tsundere Matsuri sister to experience completely subjectively!
