My mother-in-law's stepchild who came to my house due to my father's remarriage is a classmate girl who is reputed to be the cutest girl in school. - Living under one roof with a girl who could only look at it until now! On the contrary, living in a shared room! My room is becoming a maiden every day, and my space is extremely small. In addition, thanks to my sister-in-law's wide friendship that I suddenly made, cool girls come to play! At first, I didn't like it because it was noisy, but I could watch panchira as much as I wanted, and sometimes it was even more erotic.
