From what I could tell, there is a sister character who is trying thing, which she found in an erotic book, on her brother (you, as it is in POV). Decent story for a hentai, 5/10.
The art is great, 10/10. I haven't seen a hentai with this quality of art in a while. The animation is also very smooth. Often a hentai will use nice art to make up for crappy animation, but this is an exception.
The sound Is nice, 10/10. The one thing japan seems never to be short of is industrial technology, like microphones. They also have schools which give degrees in voice acting. Generally speaking, most anime and hentai have great sound quality depending almost entirely on where you stream/view them from.
The character design is fantastic, 10/10. Would fap again. The main character is absolutely adorable.
As far as enjoyment goes, it warms my heart to watch this 10/10. However, there is very little actual sex in the main video. Though there is two shorter OVA videos released along side the main. These make up for that.
Overall, my heart says 10/10, my calculator says 9/10, and my manhood says to go watch it again.
I really enjoyed this hentai. I think that you will too (unless you're pedophobic, in which case, you'll probably find yourself uncomfortable watching this.
