Thanks for sharing these El Bondage sets, Totomi-kun! Works by this artist are almost impossible to find.
What I like most about this artist is that he manages to capture the distinctive art styles of different series. I also really like the bondage situations he puts his damsels in -- particularly the way that they're gagged in virtually all of his images. It's very rare that you come across a combination as winning as that, especially with old-school art.
