Take my hand away and tell her to grind against it if she wants to cum.

Theo abruptly removes his hand from the rope, leaving Kelly trembling on the edge. Her eyes snap open, a mix of desperation and confusion in her gaze.

"If you want to cum," Theo says with a smirk, "you'll have to work for it. Go ahead, grind against the rope."

Kelly whimpers, her hips twitching instinctively towards the source of stimulation. But her bonds severely limit her movement. With her thighs and ankles tightly bound together, she can barely shift her lower body. The box tie and ceiling attachment further restrict her range of motion.

Determination flashes in Kelly's eyes as she struggles to meet the challenge. She attempts to thrust her hips forward, but the movement is stilted and awkward. The effort causes the nipple clamps to swing, sending jolts of sensation through her chest.

"I can't... it's too tight," Kelly gasps, frustration evident in her voice. She strains against the ropes, managing only small, jerky movements. Each tiny shift brings a burst of friction against her sensitive areas, stoking the fire within her but never quite enough to push her over the edge.

Kelly's face contorts with need and exertion, sweat beading on her skin as she fights against her bonds. The cameras capture every moment of her struggle, her desperate attempts to find release despite her severely limited mobility.
