Amanee is a one episode OVA based on an adult manga of the same name. The title is actually Amanee!: Tomodachinchi de Konna Koto ni Naru Nante! That single episode is 25 minutes long. The manga, which goes by just Amanee, is one volume at ten chapters, and was published in 2011.
Ryouichi goes to his friend Yuu’s place to play video games, like they do sometimes. It turns out that Yuu’s aunt Yui has come to visit, and she joins them. But it soon becomes clear that it’s not a video game she wants to play with. It’s Ryouichi.
So basically this is about a teenage boy being seduced by the married aunt or elder sister of his friend. This older woman proceeds to take his first kiss and his virginity. The taboo housewife/high schooler action here.
I would like to say that the animation is the only area where this hentai falls flat, but it isn’t. The whole thing feels very rushed, with minimal artwork and no detail, just everything in block colors with some shading, if they remember. The dialogue is the sort where any hentai-eer wouldn’t even need subtitles to understand what they are saying; it is that generic. Even for a hentai, the story is poor, with a literal “meet and fuck” atmosphere about it. I can list all the things that made me dislike this episode, but what is most frustrating is that it managed to get some things right, and so we get a brief glimpse of what it could have been, if it had followed through. And that’s what saddens me the most. With the theme and everything, it could have been so much more.
