Roxy's eyes widen as she's led into the pulsating, UV-drenched chamber, her heart pounding in anticipation. Dr. Sparky secures her to a St. Andrew's cross, the cold, hard wood a stark contrast to the warm, tingling sensations spreading through her as the UV light bathes her skin. The doctor's wand, humming with electric promise, traces lazy patterns over her curves, each shock sending jolts of pleasure-pain coursing through her, illuminating her kinky journey into the depths of sensation.
