Bob Georgeson, Shinju, 2005, Musical jewel box, pearls, chopsticks, lace, photos.
In my study of erotica one of the more bizarre sexual practices I have come across is the so-called Japanese 'art' of rope bondage known as kinbaku. I am not going to condone or explain it...Google it if you are interested in such things. Shinju is the Japanese word for pearl, but also refers to a particular form of binding of a particular part of the female anatomy...you can figure out the rest...
