Sarianna squeaks in surprise as the straps tighten around her, and follows the demoness meekly as she's pulled along by the chain. She lets out an "oof!" as she's shoved down onto the bed, and looks a bit confused at the comment about 'precious energy'. Something foggy in the back of her mind told her tat she was just being used as cattle, but the charm's magic held sway, ultimately convincing her that her mistress had no intention of harming her, that she, ultimately, knew best. She merely watched the succubus, awaiting her next decision.
