PPPD-766 One week of living together as a tsundere with the unfriendly big-breasted girl next door Hitomi

My neighbor, Hitomi, has always been unfriendly and cold, and I don't like her a bit... - However, my parents got along well, and my parents decided to take care of me for a week while I went on a trip! - Contrary to her blunt attitude, she is a big sister who actively interacts with others! - They watched my AV without permission, and invaded my bath in school swimwear...! - Then I suddenly realized. - Sister, is it actually about me...? - A completely subjective experience of living together with the tsundere big breasted sister Hitomi!
