It was a heady sensation, the power of humiliation. She would do anything he asked, no matter how much she despised him or the acts he bad her commit. But, docile cooperation, even if fearful, was amusing only for so long. And then, then he longed for the screaming, the pleas of no, don't, anything.
He watched the two women for a moment, but Walden was ready for the real games now that the warm-ups were complete. Seeing a chair nearby, he pulled it closer to the bed, positioning it to give their audience the best views. Then he took up the end of the chain and pulled his pet away from her partner.
Casting a spell or two, he created a loop-hook in the ceiling and threaded the chains through it so she now stood in the centre of the room, arms in the air, chains supporting her weight just enough to put strain on her arms as she hung there. Then he lengthened the chain so that the threaded end hung between her breasts and he transfigured the end into clamps, which he clipped almost absently to her nipples so that any struggles to free her hands would pull on the clamps.
"Such a good girl," he said with a smile and he let his robe fall from his shoulders, twirling his wand between his fingers as he thought of what to do to her next. "You've earned a reward."
With that, he removed the curse that made her biddable and backhanded her again before casting a short burst of the Cruciatus. Smirking evilly, he cast a hex that would create the phantom sensation of fingers moving inside her as he ended the pain. "Your reward is that you may now scream and struggle all you like." He stepped around behind her, holding her hair to one side and nipping at her neck almost like a lover would. With his free hand, he reached around her body to give the chains a none-too-gentle yank. "So long as you remember that any mistakes you make will be marked on her body, pet."
