Doji to Miss

Want to become even closer? My younger sister's friend, the beautiful high school girl Meari, seems to have taken a liking to me for some reason!? She "comforts" me after I have a fight with my sister, and even though my sister is in the next room, she invites me to "continue♪"!! From the popular work "Sister's Friend x Secret," where I get seduced by my sister's friend and have intimate sex in secret, to a quiet literary girl, a lively tanned girl with a regional accent, and a slightly irresponsible, languid high school girl... this is a gem of a book where sweet beauties aggressively seduce you!
