Hidden behind tinted windows, a busty brunette, her lush curves barely contained in a low-cut top and tight jeans, boards the near-empty bus. She takes a seat near the back, her eyes meeting the voyeur's in the rearview mirror. As the bus trundles along, she begins to touch herself, her hand sliding up her thigh, fingers dipping beneath her jeans to stroke her wet pussy. The voyeur watches, entranced, as her breathing quickens, her nipples hardening against her shirt.
