Kuuki Ningyou to Imouto

A talking sex doll appears in the room of a naive high school girl! It seems that the sex doll that her brother bought came to life and can talk..? It's a little more vulgar than usual, but sometimes it's a little warm and fuzzy. A heartwarming comedy about an adolescent schoolgirl and her sisterly sex doll that transcends the R-rated barrier!
