Ishuzoku Reviewers

Both are set in fantasy setting and have incredibly perverted and horny protagonist(s), who spend almost entirety of their free time banging ladies.
The only difference is that Rance is an actual hentai, while Ishuzoku Reviewers is merely borderline hentai and most of the good and proper stuff happens off-screen.
