(Vertical 9:16), portrait video, early 2020s AI-generated style with subtle artifacts and soft rendering, photorealistic details. Afternoon in an empty milk tea shop, warm yellow indoor lighting. A beautiful voluptuous 40-year-old Chinese mature woman, the shop owner, secretly doing erotic live streaming behind the counter. She has an elegant oval face with delicate dignified mature features, seductive phoenix eyes with subtle crow's feet, full plump red lips, fair flawless porcelain-like skin glowing softly. Voluminous wavy chestnut long hair casually draped over her shoulders. Her massive heavy G-cup breasts are fully exposed, black lace bra pushed up above them. She wears a white short-sleeve uniform T-shirt unbuttoned to expose her chest, black tight pencil skirt pulled up to her waist, black pantyhose ripped open at the crotch with no panties underneath, and black flat work shoes. She is half-sitting on a small plastic stool with legs spread wide apart, knees pressing against the inner counter panels. One hand vigorously kneads and pinches her soft heavy left breast and erect nipple, while the other hand's middle and ring fingers are deeply inserted into her wet glistening pussy, rhythmically thrusting in and out, producing lewd wet sounds and dripping arousal fluids onto the floor. Her face is flushed red with lust, biting her lower lip, looking seductively and shyly at the phone camera while moaning softly in pleasure. Cluttered background with milk tea machines, stacks of paper cups, straws, syrup bottles, and cash register. Highly detailed realistic skin texture, glistening fluids, sensual and naughty secret atmosphere. Total duration exactly 8 seconds, cinematic slow motion, smooth natural movements.
