Sei Dorei Gakuen 2

There's only two words that can describe sex scenes that have been directed by the great Teruaki Murakami: Filthy and Violent.

There no love or kindness, just pure, primal carnal desire in animated form. If you're a hopeful, starry-eyed vanilla fan, then there's absolutely nothing for you to see here. But for everyone else who are really into women guzzling cum, being forced to orgasm, and getting fucked in every available holes of their bodies all at the same time... then this is a series for you.

Story isn't exactly a strong suit for this kind of smut, all you need to know is that it ... is very well animated and has a lot of energy, which I think is something crucial that most animated hentai always lack. Decently voice acted as well, considering the frantic energy of the material that they have to work with. I personally wish the male characters talked a little less, lol. It also has juuust the right amount of filth -- there's a lot of bodily fluids flying around, including pee, but it doesn't go as far as showing scat or blood.

Overall, I highly recommend this.
Obviously not going to be a series for a lot of people due to the genre, but... this ain't for them. It's for us.
I'm looking forward to GOLD BEAR's next work.
