My grandmother's house that I visited after a long time. I thought that the melancholy time spent surrounded by relatives would begin, until I met her. A girl who lives with her mother and is three years younger. In my memory, I was still a student, but now I've grown up to be a woman with glossy skin and big breasts that makes her uniform burst. A secret summer vacation that I can't tell my parents and my cousin who is adolescent and curious about sex.
