If you want anime and have a sick sense of humor, hentai is right for you. I particularly recommend La Blue Girl (which I recently picked up in Hong Kong on VCD). It's funny (but then again, I like Doug Winger's satirical take on furries). Hentai usually involves some girl wandering through a forest and then getting raped by some mythical beast or plant or something, and then getting infected and turning into some beast-human hybrid with multiple flailing penises which are used to suck the life out of its subjects (probably by over-stimulating them or something).
