This is really two separate hentai under one series, the first one is the Mourning Wife which follows the widow of a recently passed husband. The family members decide to get revenge on her (they blame her for his death) by raping her. This eventually turns into a threesome and an open relationship between the three of them. The art is pretty good and the animation isn't to bad, but the audiois pretty poorly recorded and hurts the hentai. This makes it a decent hentai but really not to much better than the average one out there. So by itself I'd give it around a 6/10. The second one is called Landlady Mie. The story on this one also follows a widow, but not nearly as recent, and the restaurant she runs with a young man that her daughter is in love with. Eventually the daughter convinces the young man to begin a relationship with her despite there being some signs he really is interested in the girls mother. However, the daughter catches her mother masturbating while thinking of the young man and comes up with a solution. A three way relationship with both mother and daughter and starting the relationship with a threesome. This one has similar art to the first episode, but none of the audio issues. It also does away with any of the rape and awkward conversion from rape to consensual sex. Overall it's a much better hentai with a better story, characters, and enjoyment despite the start and ending being very similar. By itself I would have given it around an 8/10. While both make this series a 7/10 for me, it still a pretty good one that people that like harem, incest, and threesomes will enjoy.
