This was the first hentai I have ever seen. Was quite young, used to watch it careful not to get caught by my mother. xD
The story is not really that amazing, but for a hentai, it is acceptable, even alright I can say. As a kid I was quite fascinated by it to be honest, hah. The Art is something I also enjoyed at that time, and still do. Also loved the sex scenes, of course.
The characters are each unique in their way, and that's awesome for a hentai where how hot the female characters are is probably the one important thing the audience is interested in. But in this one, each one of them behave in their own way.
I enjoyed it a lot for obvious reasons, and even after completely finishing it, I used to rewatch some scenes, again, for obvious reasons. :"D
