Aki Sora

Sora Aoi has been saying "I love you" to his gorgeous older sister Aki ever since he was a young child. He finds it more harder to sacrifice such conveniences now that he is older than he did in those earlier, simpler days. Sora begins to doubt his affection for his sister when Aki shows him that her feelings for him go beyond sibling love. They consummate their love in secret after realizing how much they love one another. They must now conceal their love from their families and everyone they know in a culture that will never comprehend it. Sora quickly begins to question his feelings for his sister as he experiments with new types of love with women he meets and that are not recognized by society.
