What I would describe as the de-facto ero comic for those that like the more mature woman (large breasts and hips). No room for lolis or different fetishes/ preferences here. The story is fairly typical and doesn't really go anywhere further. Shinji proceeds to have consensual relations with Nami and later Yumi (with Nami's persuasion) and then later both. Variation comes in the form of the outfits they wear, scenarios they are in (in public, outside, in the next room to where they are supposed to be entertaining guests). Although somewhat interesting and exciting since it changes each chapter, I do feel there is alack of drama that can drive the story into a more interesting area. Once you have read a few chapters, you generally know what is going to happen in the next one albeit changes in setting and costume.

Later in the series, a little bit of backstory is explored for Nami including the introduction of a rival/ previous fling Nami had. He is introduced, swiftly NTR'd/humiliated during a meet up with Nami by Shinji and then Nami and Shinji make their relationship official - all in two chapters. I think if this dynamic was explored a little more there would have been some more interesting dialogue and changes in their dynamic. However Nami never really changes her opinion for Shinji thus becoming more of a one-dimensional character only there to serve Shinji (which is probably a sexual preference in of itself).

The series doesn't really end, just fizzles. The last chapters are mostly the same set up and then sex as a conclusion. Near the end of the second volume, Yumi finds out about her husband's infidelity much to her surprise but this is not explored in the subsequent chapters. So what happens? Do they continue to live with one another just cheating on each other?
I guess asking these sorts of questions in a hentai is really asking the wrongs sorts of questions

If you like what you see in on the front cover then you'll enjoy this manga for what it is. Beautiful ladies having consensual sex in different outfits and locations. If you want something more cohesive to make things more dramatic or exciting above the surface level - you'll have to look elsewhere.
