Try wiggling the rope back and forth against her clit.

Theo's hand moves to the taut crotch rope, fingers grasping it firmly. With a subtle motion, he begins to wiggle the rope back and forth, creating a rhythmic friction directly against Kelly's most sensitive area.

The effect is immediate and intense. Kelly's eyes fly wide open, a strangled cry escaping her lips. Her entire body jerks in response, the sudden movement causing the nipple clamps to swing and tug at her tender flesh.

"Oh god!" Kelly gasps, her voice high and ****. The steady, insistent rubbing against her clit sends waves of sensation coursing through her body. She pulls instinctively at her bonds, but the ropes hold firm, leaving her helpless to escape the overwhelming stimulation.

Kelly's thighs tremble violently, muscles tensing as she teeters on the edge of release. Her breaths come in short, sharp pants, punctuated by low moans she can no longer hold back. The pressure builds relentlessly, each small movement of the rope bringing her closer to the brink.

"I can't... I'm going to..." Kelly whimpers, her words trailing off into incoherent sounds of pleasure and desperation. Her hips buck involuntarily, seeking more friction even as her mind reels from the intensity of the sensations.
