Say "It is, what do you think?" Then turn on the sybian halfway through her response.

"It is," Theo confirms, his fingers working deftly to secure the intricate knots. "What do you think?"

Kelly takes a deep breath, trying to gather her thoughts. The ropes pull her arms further back, making her increasingly aware of every subtle movement. "It's... different," she starts, her voice strained from the position. "I didn't expect it to be so--"

Suddenly, a low hum fills the air as the Sybian springs to life beneath her. Kelly's eyes widen in shock, her words cutting off abruptly. The vibrations course through her body, making her thighs tremble against the rope bindings.

"Oh!" she gasps, unable to contain her reaction. Kelly squirms atop the Sybian, instinctively trying to lift herself away from the intense sensations. But the frog tie keeps her firmly in place, leaving her no escape from the relentless vibrations.

"I... I..." Kelly struggles to form coherent thoughts as the Sybian's ministrations send waves of pleasure coursing through her. Her façade of cool indifference crumbles, replaced by a mix of shock, embarrassment, and rapidly growing arousal.

"Fuck," she whimpers, her hips unconsciously rocking against the machine. Kelly's cheeks flush crimson, mortified by her body's betrayal but unable to stop herself. The cameras capture every twitch, every gasp, as she fights a losing battle against the mounting sensations.
