Probably the most cumflation focused VN on the market, it's a masterpiece in knowing what the focus is on for the art and embraces it fully. It's story is ok, being more of a world builder to allow it's characters to shine. It's characters, are more than single note, you get to understand who they are but also see multiple sides of most of them.
The length is not great, but considering the storyline, it's also not overstaying it's welcome.

Overall, if you like this genre of material, and with the very sparse choices on the market for cumflation/stomache buldge, then you won't regret this. It's not good because it's first to market for a niche genre, its a good VN that also happens to focus on this genre, and won't be outclassed by next seasons game on the subject.
