Aki Sora is an interesting creature in itself. It originated as a manga about the sexual relationship of a pair of siblings, serialized in Champion Red and classified in the seinen category. One look at the manga makes you wonder why this is not a hentai… various issues regarding sexuality are explored, including but not limited to incest, exhibitionism, lesbianism, and so on. The manga is hard-hitting stuff, with sex present in practically every single chapter. Go read the scanlations on Manga Fox and you will get what I mean.
So one would expect the animated adaptation to be filled with nothing but sex, right?
