Mid close-up of a young woman’s lower body, from lower back to mid-thighs, seen from behind and slightly to the side. She is in an exact ballet pose with her right leg lifted high and extended backward, knee slightly bent, foot fully pointed in a correct anatomical ballet pointe position. She wears a white sleeveless leotard, (lower part visible), and a fluffy pink lace tutu. Completely nude underneath the tutu, no underwear. A man stands closely behind her. He is penetrating her from behind with his stiff erect penis, fully inserted. His hips and the base of his cock are visible as he fucks her. Her intimate area is anatomically realistic, soft and natural, flatter and less protruding. Her anus is naturally visible above the penetration. Soft natural window light, realistic skin texture, highly detailed photorealistic style, sharp focus on the lower bodies, the penetration, her naturally visible anus, and the exact ballet leg position from the reference image.
