Under the harsh fluorescent lights, she indulges her taboo fantasy. The cool metal of the plug contrasts with her warm, eager flesh. She imagines the eyes of the unseen customers on her, fueling her desire. She grinds against the plug, her moans muffled by the hum of the refrigerators. She can feel her orgasm building, her body tensing, as she fucks herself with the plug. Just as she's on the brink, the sound of footsteps echo through the aisle. She quickly removes the plug, pulls up her panties, and straightens her coat, her heart pounding with the thrill of her near-capture.
