Kikkou (karada) (self)-bondage technique. Translated!

There are many forms of karada. If our model had large breasts, you could consider using the ropes to further demonstrate her assets. For example, use the rope and cross it in front three times. When the rope is looped near the top, it can go through both top and bottom of the chest, highlighting the breasts.
Here we also tied the model’s arms.
If the ropes isn’t separated between her legs and instead pass through the middle, then when the model struggles the rope will become tighter. It is a more evil treatment.
