This is a continuation of another series and requires you to see it if you really want to follow the story. As a stand alone the story is there enough to hold the hentai together but will leave you confused as to motives and why things are happening.
The strongest thing this hentai has going for it are the art and animation, which both are really good for a hentai. The main girl has a
great design and looks really sexy in most of the outfits and bondage gear she wears. The piercing are also a nice and fairly rare touch in hentai.
However, I couldn't get into this at all despite her looks. NTR where this a good amount of focus on the husband and the emotional torture he goes through, plus the rape happening throughout instantly kills any enjoyment for me. I just can't enjoy people being inflicted with emotional pain and trauma. The ugly bastards inflicting just pushes it further out of my taste.
Overall I can see why someone into NTR and rape would enjoy it as the animation and art are really well done, but if either of those genres bother you or extreme bdsm/enema play then stay away from this one. This one is strictly for people with those fetishes and no one else.
