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.

Art: 10/10

First of all, the 10/10 rating I am giving this is based on hentai standards, not anime. I feel the two are such different categories (especially when it comes to story) that it's not right to judge hentai in the same way as anime (though I will admit many hentai still annoy because of their idiotic plots).

Story - 8/10

The story of Aneimo (which despite it's name has no incest) is a fairly standard "harem-romance" story (at least for a hentai). The main character Takumi's father has just let two teenage sisters stay at their house and now Takumi is supposed to consider them his step-sisters read more

While neither really has much plot (obviously both being hentai) both have great girls and great sex scenes. The art of both has a similar style that is nice. Both are harems with one central girl, but the rest of the female cast is also exceptional.
- Hentai harems where there is one main love interest but the guy gets sidetracked along the way
- High school students and the guy has known some of the girls for a long time

- Harukoi Otome has sibling incest
