Summary: An above-average hentai with some semblance of a plot. There is no actual incest; not even of the stepsister variety.

Story: 7/10

Kudos to the animation studio for not deviating from the plot of the game. The story is about a high student student named Takumi whose father suddenly declares to him that he now has two sisters. They are not officially adopted by his father, and he shares no distant blood relation to them, hence the no actual incest. In a nutshell, the story deals with his getting to know his "sisters", and his two neighbors, who also have the hots for him.

Mixed Feelings
Ah, one of the first hentais I have watched. Aneimo is a hentai that follows the classic h-game storytelling. A vanilla story of a man who finds love as girls come flying into his life as he gains adopted family members and of how this fact changed the girls who were already gunning for the man. The story seems quite honest at first, but the setup for sex scenarios is kind of forced. Can't really blame it though, it's hentai so the sex gotta be shoved in somehow, and fast. ¯\_(ツ)_/¯

The strong part of the story is that it sets up a good exposition. The ...
