A lot of random tentacle/demon hentai obviously takes place in some sort of freaky underworld, but I rarely see hentai based explicitly on the christian idea of eternal punishment. In fact, this slightly tacky photoshop is nearly all I've ever found, which is odd as I would expect the subject to be fetishized like crazy. Do any manga fall into the category?
That first one is probably too guro...nevermind the fact that it just plain sucks.Also I neglected to mention it has a name, stygiophilia, and there used to be a hentai site devoted to it but it's long gone.
