Origami Underground

Origami Underground s the place to find erotic origami on the web. All folding diagrams are free, but don’t expect much from them. They aren’t the cutest or the more detailed models you will see, but they can give you good times. There are models of people together and alone, female and male anatomy and animals. The site has a Origami Books recommendation page. The first two books on the list have nice naughty origami models: Very Naughty Origami and Pornogami: A Guide to the Ancient Art of Paper-Folding for Adults.
