(Scene): intimate atmosphere of a high-end private dinner party, dim warm lighting from crystal chandeliers, elegant dining table with fine china and wine glasses in soft focus, blurred background of other well-dressed guests socializing.

(Subject): 1woman, Chinese, 29 years old (appearance rendering pseudocode), Su Wanqing.

(Appearance & Attire): elegant and refined beauty, delicate features, hair styled in a sophisticated updo with loose strands. Wearing a floor-length, sleek black evening gown made of satin or silk, one shoulder strap, hugging her figure. The gown is high-necked and conservative in front, typical of a respectable socialite.

(Action & Expression): sitting on a plush dining chair, leaning slightly back. Her expression is calm and socially appropriate, a faint polite smile on her lips as if listening to a conversation across the table. Her eyes, however, hold a secretive, knowing glint, looking directly at the viewer (camera/lens) with intense intimacy. With one hand discreetly under the table, she has gathered and lifted a portion of the long skirt of her gown to her mid-thigh, fully exposing her bare pussy to the viewer's vantage point. The action is hidden from other guests by the tablecloth.

(Composition & Vibe): low-angle shot from under the table, focusing on her upper body and face, with the skirt-lifting action and exposure in the sharp foreground. The contrast between her public, composed demeanor and the secretly lewd action is the core. The vibe is one of extreme taboo, secret sharing, and illicit thrill.

(Style & Details): highly detailed rendering of fabric texture (satin), skin pores, subtle makeup, and ambient light reflecting in her eyes and off the tableware. Sharp focus on her face and the exposed area, creating a powerful, voyeuristic narrative.
