Although there are nuanced differences in the methods employed by different people, here I'll explain a very basic way to bind the chest in preparation for suspension.
This step removes the bound one's freedom to move their arms, so in a way, it's one of the steps where they can feel the deepest sensations of bondage.
How you hook the rope is what determines how tight it will be.
When people are first starting out, their rope tends to be rather tight, so please be careful.
The rope should be wrapped around the point just above the center of the upper arm. (The top of the armpit, as viewed from the front.)
If you run your finger along the upper arm from top to bottom, you should find a spot that's a little sunken in. The rope should be wrapped around the area just above that spot.
In order to fasten the rope, I use a three-point edge.
In the above image, I've slipped the excess end of the rope into the chest rope in order to keep it taut, so that I can smooth it out.
In the below image you'll see me doing it with one hand. I use my other hand to support the body.
Smoothing is a very important step in the process. If the rope is simply left on the body without smoothing, it could pull or pinch the skin. Smoothing the rope can greatly enhance the sensations felt by the bound one.
Smoothing should be done on any rope that touches the skin, whether it be on the arms or the legs.
Please slip the rope through from behind and then pull it down from the top for barring. If you do it the opposite way, it will cause rope to get stacked up in the armpit, which is a rather confined space, and could lead to numbness.
This chest barring is done in order to prevent the ropefrom slipping up to the neck during suspension.
Sometimes in bondage films, or porn, they don't do barring for visual reasons, but you should make sure to always do it when you're starting out.
As I explained in the "How to Handle Rope" section, you can tie it in a way so that the new rope isn't stuck around a knot, but I think this way looks the best.
It'll look the best if the midpoint between the upper and lower rope falls just above the center of the upper arm.
Make sure you don't wrap the rope too close to the elbow. Also, it's important to balance the tightness of the upper and lower ropes. As you go along, it's common for the lower rope to get tighter, so please be careful.
The ideal situation is to end up with equal levels of tightness for both the upper and lower ropes.
You should use square edging. You can also use a three-point edge like with the upper rope.
Please fasten the rope tightly, like you did with the upper rope.
This time, however, don't just slide the rope through. Use your finger to push in the rope to the body so that the barring fits well in the crevice.
Please make sure not to pull the barring too tightly here. Just let it sit on top of the rope that you pushed in with your finger.
Don't pull it with your fingers. If you pull the barring rope and try to make it fit, it will make it tighter than necessary.
Depending on how much rope you have left, you can tie it so that it stays out of the way. If you have a lot left over, you can also tie it around the back rope in a spiderweb fashion.
