See what I mean? Her hips are lifted up off the deck and she’s rolled up onto one side. Her fingers are stretching out to the side grasping for anything, and with all of that effort, you can see that her hands remain exactly in the middle of her body tightly secured to her booty. Arms are still stretched, fully extended, and welded together from wrist to elbow.
By the way, it’s so critical that her ankles are crossed and her knees and thighs are NOT tied together. Because tying her ankles this way brings them in closer to her wrists putting more tension in the tether and eliminating any potential slack in the crotch rope holding her wrists down.
It’s a beautiful system of dominant restraint where each component works in tandem with the others strengthening and enhancing the bondage and the damsels helplessness.
