Photorealistic live-action cinematography, soft even indoor light, natural skin texture and visible pores, vertical 9:16 frame.

The camera is a photographer's camera at a private one-on-one shoot. It is fixed on a tripod at hip height and never moves. The woman performs directly to this lens for the whole clip. She is the only person in the clip and no other person ever appears; no hands other than her own enter the frame.

She is the young Korean woman in the source image, completely unchanged: long straight black hair with a blunt fringe, large bare breasts, a black lace garter belt at her hips and black lace-topped thigh-high stockings, nothing else on her body. She keeps this same face, hair and body for the entire clip and never turns into anyone else.

The same white bedding, white pillow and soft even indoor light, unchanged. The room is quiet: a soft room tone, the rustle of bedding, and the occasional click of a camera shutter.

The motion has three beats. FIRST THREE SECONDS: still smiling into the lens, she rolls over onto her front and pushes herself up onto her hands and knees on the bed, turning around so that her back is to the camera, and looks back over her right shoulder into the lens with a bright playful smile.

NEXT FOUR SECONDS: she lowers her chest and shoulders down onto the bed, arches her lower back and pushes her buttocks up and back toward the camera, opening her knees wider so that her vulva is fully exposed between her thighs and centred in the frame, and she holds that pose, still looking back over her shoulder into the lens and smiling.

LAST THREE SECONDS: she reaches back with her right hand, lays her fingertips on the side of her own buttock and pulls it aside a little, opening herself further to the lens, and holds completely still while she keeps looking back and smiling.

Throughout the clip she keeps eye contact with the lens over her shoulder between movements, cheeks flushed, laughing lightly, clearly enjoying being photographed. Her expression stays cute and cheerful and never turns pained or blank. Her exposed vulva stays centred in the frame in sharp focus and correctly formed, with the outer labia, the inner labia between them and the opening in their correct positions.

Avoid: any second person in frame, any hands other than her own, her lying back down on her back, the camera moving, her getting up off the bed, any clothing appearing on her body, a pained or blank expression, any change to her hairstyle, garter belt, stockings or body shape, and any extra or deformed limbs.
