Amazing! Never thought I'd see hentai based on Brother, Dear Brother (Oniisama E).
BTW, I call the series Brother, Dear Brother as this is the title used on the fansubs since 1996/1997, when Technogirls started to do the series, but now the series is being offically released in Anime-Sols site and they use only Dear Brother.
