Say "Let me add some encouragement then." and move behind her with a leather flogger, teasing her ass with it.

"Let me add some encouragement then," Theo says, his voice low and teasing. He moves behind Kelly, out of her line of sight. She hears a subtle whisper of leather and tenses, unsure what to expect.

Kelly gasps as she feels the soft caress of leather strands against her exposed backside. The flogger traces lightly over her skin, raising goosebumps in its wake. Her body quivers with anticipation, the new sensation adding to the already overwhelming mix of stimuli.

Acutely aware of the cameras capturing her every reaction, Kelly bites her lip, trying to maintain some composure. But as the flogger continues its teasing dance across her sensitive flesh, she finds it increasingly difficult to stay still.

"Oh!" Kelly exclaims, her hips jerking forward instinctively as the leather trails lower. The movement causes the crotch rope to shift, sending a jolt of pleasure through her core. The nipple clamps swing gently, adding to the cascade of sensations.

Kelly's breath comes in short, sharp pants. She tugs at her bonds, torn between wanting to escape and craving more. The cameras seem to zoom in on her face, capturing every nuance of her conflicted expression - the mix of apprehension, arousal, and growing need etched clearly in her features.
