Work her up to another edge, then turn it off again.

Kelly's world narrows to the relentless sensations coursing through her body. With her mouth held open and tongue extended, she can only produce muffled, unintelligible sounds as the Sybian works her towards another peak.

"Nngh... puh... pleah..." she babbles, drool trickling from the corner of her mouth. Her eyes roll back, lids fluttering as she approaches the edge once more. Kelly's hips buck wildly against the machine, her bound legs trembling with the effort.

Just as she teeters on the brink of release, the vibrations abruptly cease. Kelly's eyes snap open in shock and dismay.

"No!" she wails, her voice hoarse and desperate. "No, no, no! Please!"

Frustration and need overwhelm her. Kelly thrashes against her bonds, tears streaming down her flushed cheeks. Her chest heaves with ragged sobs as she's denied release yet again.

"Why?!" she cries out, all pretense of composure utterly shattered. "I can't... I need... please!"

Kelly's body trembles uncontrollably, wound impossibly tight with no outlet for relief. She whimpers and pleads incoherently, broken by the intensity of her frustrated arousal.
