If you like lolis, you'll like this. Probably a lot.
Story is nonexistent, really. A fourth grader and a young guy meeting up, as they usually do, and that's about it. In a genre about sex, story isn't something you really need that much.
Art was surprisingly good for a hentai. Pretty smooth and enjoyable to look at.
Sound is okay. Fits the scenes well but there's not much to say.
There were two or three comedic moments thrown in, but I believe it was beneficial, at the very least, it didn't do anything wrong.
I enjoyed this, and anyone into lolis will.
