A girl is having vaginal sex with a man, in the cowgirl position. The cowgirl position is with the girl facing the camera. ​Photorealistic close-up portrait based on image_21.png of a young woman with a short, dark bowl cut and straight-cut fringe covering her forehead. Bright, piercing ice-blue eyes with intricate iris patterns, looking directly forward. A multitude of fine, scattered freckles across her nose, cheeks, and forehead, showing natural skin texture. Mouth is wide open in an animated, joyous, wide-mouthed shout, revealing both upper and lower teeth and her tongue. The expression is intense excitement and direct connection. Wearing a black mandarin-collar top. Natural, bright indoor lighting with shallow depth of field. Razor-sharp focus on her face, while the background is a soft, blurred bokeh of an indoor setting with indistinct figures and a yellow horizontal line. High-resolution, cinematic quality.
