What a sweet sounding "little sister" and a presence full of immorality. Everyone has probably imagined the scenery of having a yatte with their younger sister at least once. In order to make this work more immoral as a younger sister, we brought in Yoji Aoi, who is an active lolita novelist, as a scenario writer, and focused on not only the play but also the drama part. A full-fledged lolita AV that can withstand the appreciation of adults. Immorality SEX with my brother in the last wedding dress is the best highlight.
