Rio was one of the best artists in this fetish niche but he retired from it a year or so ago. He will be greatly missed. I did manage to exchange a couple emails with him and he drew two of my requests: 1) a castrated house husband, and 2) a gelded pony play guy.
Hot doujinshi published by Pururun Estate. Only 2 chapters were published, unfortunately, because it really showed a lot of promise.
I’ve included the artwork here although there are a few other online places where it can also be obtained.
Here’s more info about the artist that illustrated “The Spanish Leather”. “House of Bondage” is available from alta-clamour for $75 which is out of my price range.
If anyone has more info about or images by RAMM I’d love to see them.
