Apply nipple clamps and attach them to ceiling.

Theo reaches for a pair of metal clamps, their chain glinting in the studio lights. Without warning, he attaches them to Kelly's erect nipples. She gasps sharply, the sudden pinch sending jolts of sensation through her body.

"Oh fuck!" Kelly cries out, her back arching involuntarily. The movement presses her more firmly against the Sybian, causing her to whimper as the vibrations intensify.

Theo then secures the chain connecting the clamps to a hook in the ceiling, pulling it taut. Kelly finds herself in an impossible predicament - if she sits fully on the Sybian, the chain tugs painfully at her sensitive nipples. But to relieve the pressure, she must raise herself up, using her already trembling thigh muscles to lift off the vibrating surface.

"There we go," Theo says with satisfaction, stepping back to admire his handiwork. "Now you have a choice to make with every moment."

Kelly's breath comes in short, sharp pants as she struggles to find a bearable position. She rises up, relieving the pull on her nipples, but immediately misses the intense stimulation against her clit. After a few seconds, her legs begin to shake with the effort of holding herself up.

"I can't... it's too much," Kelly whimpers, lowering herself back down. She cries out as the chain goes taut again, tugging at her sensitive flesh. Tears prick at the corners of her eyes as she realizes the full extent of her predicament.

"Please," she gasps, all pretense of cool detachment long gone. "I didn't know it would be like this." But even as she pleads, Kelly can feel her arousal building, her body responding to the intense sensations in ways she never expected.
