WARNING: BONDAGE CAN BE DANGEROUS, DON'T TRY THIS ALONE, YOU MUST LEARN BONDAGE FROM SOMEONE WITH EXPERIENCE.
This site shows bondage photos of two different styles:
Shibari is a traditional bondage technique and art from
Japan, its origins go back many centuries. You will find explanations
and hypothesis on its origins on other web sites and books. It is of
military origin (it was used to tie, dominate, humiliate and torture
prisonners) and it is deeply rooted in japanese culture.
The bondage is also beautiful to watch. Ropes must be disposed in regular patterns. The effect is erotic arousal of the submissive (because ropes take into account energy lines and the chakras) and of the person watching.
The set for shibari is a traditional japanese house. Hemp rope is used.
The submissive is called m-jo, she is partly or fully naked.
The usual types of bondage are:
Free style bondage is better explained by comparing it to shibari.
It is not always really functional The set can be any modern environment: room, bed chair, stairs, etc.
Cotton or synthetic ropes are used. The various colors allow different effects with the skin, the clothes, underwear, etc.
The submissive can wear some clothes: underwear, gloves, t-shirt, high heel shoes, boots... All the fetish accessories can be used.
There is no formal technique. That's why it's called free form!
