This type of bondage is called shibari, and it’s different in the way you described. Regular bondage is about restricted movement, maybe cuffs or topless around wrists and ankles.
Shibari is a Japanese form of rope bondage, it is a very slow and methodical approach, where the person being bound must (generally) submit quietly the whole time it’s being done.
The aesthetics of the binding are important, it should look good, and also should work with the mechanics of the body.
It can be used as a pleasant and beautiful decoration on top of clothing, as here, or can use the mechanics of the body to bind in such a way that the body’s own movements cause stress.
WHAT??!
