You would think that a simple tie like this would be something that a strong woman like Ecko Belle could just bust out of, but you'd be wrong. Strength only works if the restraints have a weak point, but that's the beauty of high quality rope, all strength exerted from inside ropes ends up being distributed among all the ropes.
And now this leaves naked and sexy FBB Ecko helpless with just some twists of rope around her wrists and her ankles. Despite her strength she will need help to escape. And the tape over her mouth sealing it shut keeps her from calling out. It also keeps her screams of frustration in her mouth as well. Which sound she is making at any time is indeterminate.
Also indeterminate, the time when Ecko will be free again.
