Every hentai enthusiast that loves good art should watch this series. The sex scenes and animation is 11/10! Even if you don't like young girl with older men sex, it still tantalizes the senses =03. I LOVE NTR, and this series is steeped in it. If NTR is a detrimental factor, I'd subtract an extra point off of my score, but still worth a watch for the animation alone. There's not much to the story... I mean, its a hentai. If you're watching it for character development, you'll be disappointed. And again, its NTR, so that's about as much as you should expect for this series. Fora vanilla version of the same style of animation, Nudist Beach(no not Kill la Kill Nudist Beach =02) would be a perfect recommendation.
