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

The story was definitely a modern(realistic) romance. Not just with one girl but three others. There was step incest. Although i was surprised with four girls that the main character got not one scene of a threesome or more. Not even a naked mishap such as one girl undresses ready to rock his world at the same time as another. Something else worth mentioning maybe it was just my copy but the LIGHT THE LIGHT! why so bright? yes, i know the sun is bright but no need for that especially in the sex scenes. I might need to go check my eyes later.

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 read more
