Awesome extreme BDSM series. This is probably the most extreme bdsm i can think of in hentai, back from the hay-day of fetish hentai. involves just about ever fetish I can think of including scat and gore, so be careful if you aren't into that. If you are into extreme bdsm you may like this hentai, I know i did. Overall, i think its one of the best hentais I have ever seen.
