Photorealistic image of a slim young woman with short dark brown bob haircut and straight bangs, fair skin, sitting upright in cowgirl position on a man lying on his back. She is completely nude, legs spread wide and bent at the knees, feet flat on the white mattress beside his hips. Her body faces the camera slightly angled, eyes closed or looking down, mouth slightly parted. Full frontal view of her small natural breasts, flat stomach, and detailed shaved pubic area with the man’s erect penis fully inserted in her vagina, visible at the base. The man is nude from the waist down, only his muscular hairy thighs, knees, lower legs and feet visible, his hands resting on the mattress near her hips. Soft even studio lighting, neutral light-gray seamless background, clean white sheet covering the mattress. Highly detailed skin texture, realistic anatomy, natural proportions, sharp focus, cinematic photorealism, no text, no logos, no watermarks.
