You've really gotta love the Japanese. They are so much more perverted than we are, and in really creative ways, to boot. Take The Invisible Stud, for example, in which a perv gets a hold of some invisibility potion and wreaks havoc.
The animation isn't particularly crisp, but the voice acting is pretty good, and it shows a sense of humor. Of course, anime fetishists know their shit, and this isn't going to make them jump for joy, but it's sufficiently nasty, and better than average, for sure.
Retailing: Steamy, funny and a little pervy anime title.
