I just had to write a review about this. This is beyond the shadow of a doubt the funniest Hentai I've ever watched. And I've watched a lot of Hentai productions. This series may not appeal to some of you, depends if you're into incest or not. Personally, if the sex scenes are good and I assume that's what most of you are looking for (well DUH) I don't mind. The sex scenes in this Hentai are godly while at the same time vanilla-ish. Plenty of positions and the artwork is superb. Now what makes it so funny you might ask. The fact that thisseries starts innocently. Though there's plenty of sexual tension between the girls and the guy, neither side is bent on acting on their feelings. The protagonist even gets suprised and shocked when his sisters say something that might have a double meaning.

It's funny watching how the whole thing develops through certain mishaps & misunderstandings but eventually it does get to the point where the real deal happens.

As I mentioned before art is outstanding though you will find an odd scene or two, but the overall quality is still not affected. Sound is very good though not perfect, sometimes you get the impression that the characters are made out of leather but personally, the sex scenes more than make up for it.

Enjoyment - hell yeah, you will enjoy this. This is probably the only hentai out there that will make you laugh as well. I know, because I laughed for the entire duration of the first episode.
