You're right, it is the same rope that you see in the top right corner of pic 3. There are two ratcheting ropes that are clipped to D-rings on both sides of the collar. The other end of each of them is clipped to D-rings on the bondage board that my sub was kneeling on. The left rope is clipped to the left side of the bondage board, and the right rope is clipped to the right side of the bondage board. That should give you a better picture in your mind of what the CLICK-CLICK-CLICK ratcheting action does to him, and which way it forces him to move. Once you have that in mind, think about how much tougher his predicament gets with every "CLICK". *evil grin!*  Do you know what the forced angle of his thighs does in this predicament? If you get on your knees with your head leaning over a bed or chair in front of you, you should be able to move your knees more forward or more back on the floor and feel the difference. Just make sure your hands are behind your back or at least not supporting your body on the floor when you do it.
