My grandmother's house has been visited for the first time in a while. Until I met that girl, I thought the melancholy time would begin to be surrounded by relatives. A girl who lives with her mother and is three years younger than her. I remember myself in elementary school, but now I've grown into a woman with shiny skin and breasts that have grown so big that her uniform looks like she's coming off... A secret summer vacation that I can't tell my parents about puberty and sexually interested cousin.
