HUNTB-570 A stranger until yesterday! Living in a shared room under the same roof as the 1st army gi

My mother-in-law's child who came to my house because of my father's remarriage is a classmate girl who is the cutest and most popular at school. Living under one roof with a girl I could only see until now! Instead of living in a shared room! My room is becoming a maiden every day, and my space is extremely small... Furthermore, thanks to the wide friendship of my sister-in-law who suddenly formed, a lot of cool girls come to play! At first, I hated it because it was noisy, but I could see panchira as much as I wanted, and sometimes it was even more erotic than that...
