Have her sit on a sybian.

Theo's eyes light up at Kelly's challenge. "Alright, if you say so," he says with a wicked grin. He walks over to a nearby table and picks up what looks like a padded seat with various attachments. Kelly watches curiously as he sets it down in the center of the room, positioning it carefully.

"Have a seat," Theo instructs, patting the strange device.

Kelly eyes it warily, her bravado faltering slightly. "What is that thing?" she asks, trying to keep her voice steady.

"This, my dear Kelly, is a Sybian," Theo explains. "It's a very special kind of... ride."

Hesitantly, Kelly approaches the device. She runs her hand over the padded seat, noting the various knobs and attachments. Her pussy throbs as she imagines what they might do. Taking a deep breath, she gingerly sits down on the Sybian, the firm padding pressing against her most sensitive areas even through her skirt and panties.

"There, happy now?" Kelly says, her voice a touch higher than usual. She shifts slightly, trying to get comfortable. The hard protrusion beneath her sends little shivers of anticipation through her body. What the fuck did I just sit on? she wonders, a mix of fear and excitement coursing through her. But outwardly, she maintains her cocky facade. "This doesn't seem so tough. Is this really the best you've got?"
