WELL, in short this Hentai can be described as Mediocrity at its fines. Really this Hentai nothing more then Average and Nothing less. The Story is Fair, not a shitty NTR or tentacle thing, also not a Rape category Plot. This is a positive aspect, but it could have been a lot better. If instead of a Faceless Sensei having his way with student girls, I mean saving them with Sex from Whatever Nonsense. It would been much better, if the Guy were just a school student and instead of girls he would have his way with the teachers and create a Teacher Harem, ;D My kindof Fetish.
The Art was Fine, very typical to recent Hentais, where all the character look almost the same body type, big Boobs or small ones, and a nice butt. Nothing attractive actually, as always worst Part - It's CENSORED.
Sound is not worth mentioning, it was also average as was the characters that is not a good thing but also not a bad one either.
All in all it is really a ordinary Hentai, which you can watch and enjoy it quite decently.
