This hentai is excellent for a hentai, consisting of mostly sex scenes which are nicely drawn and exciting. The moe factor in this one is really high.
There are five different sex scenes: 2 with Airi and her father, 2 with Airi and her molester, and one with Airi's sister and the school's principle.
Story: It wasn't good. That can be said about every other hentai, though. As fap material it was excellent. 4/10
Sound: I really liked the voice acting and sound effects. 9/10
Character: Airi and Marina are wonderfully moe characters, but the molester and Airi's father are awful and dull. 7/10
Enjoyment: I find that I can keep coming back to this one if I ever want to fap. It's fun to watch and never gets old. 10/10
Overall: In comparison to most anime I wouldn't consider this one very good. However, as a hentai, it's outstanding and surely enjoyable to the many avid fappers. 10/10
