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!
