This picture shows a bondage model going through the process of being tied up for a photo shoot. Many bondage photographers and models prefer to use cuffs, straps and other restraints with buckles or other fasteners, because these make it easier and quicker to get the model into (and out of) the bondage positions needed for a set of pics.
However, many bondage fans like to see traditional rope bondage in the pictures and videos. This means the photographer, assistant, or another model must serve as a "rigger" to do the rope work. Depending on the required position, this can be a very time consuming process for two reasons. First, they want the bondage to look good in the pics, and second, they try, as much as possible, to be careful to avoid pain and injury to the model.
For the girls being tied up it requires patience and endurance, especially if they are tied in some of the more extreme positions. And once she's tied up, she's going to stay that way until the photo shoot is over. (Make sure you go to the bathroom before they begin!) The bondage can be uncomfortable, and if she's going to be tickled in that position, you can see why they call it tickle torture. (Which is why some bondage models won't do tickling sets.)
I found a number of barefoot bondage pictures, most of which feature rope bondage. I hope you enjoy the pics, and I hope you appreciate what these girls went through for your viewing pleasure.
