Hentai World: Alternative Dimension where the rules of Porn and Hentai apply above all others. Whether it means that people are simply sexually open, shameless about breaking every sexual taboo out there (within reason), or have a special set of rules that revolve around sex. Either way these worlds are all about sex and the exploits that come with it.

Which world would you like to start with?
