Just a single chain: that's all it took not only to render Merula completely helpless, but utterly immobile as well. From the hood on her head to the ballet boots on her feet, she's covered in form-fitting pvc; the perfect backdrop for the silver chain to snake itself around her body. Just to be sure that escape is not an option, a little tickling gave her reason to have a good struggle, but not much else for her effort. All she can do is struggle in her bondage, and hope that several screws decide to come free.
