A hyper-realistic, highly detailed erotic scene in a large open-air football stadium during daytime. A beautiful young woman with long wavy blonde hair, fair skin, full red lips and a seductive, pleasure-filled expression is riding a man in classic cowgirl position on the green grass pitch. She is facing him, looking down at him with her mouth slightly open. She wears a tight white football jersey with blue trim on the sleeves and collar, the jersey pulled up under her large, full, natural breasts so they are completely exposed and bouncing. Her lower body is completely nude, showing a very large, round, firm, pale ass and thick thighs. She is squatting and bouncing on a thick, veiny erect cock that is deeply inserted into her wet, detailed pussy, with her labia stretched around the shaft. One of her hands reaches down between her legs to hold and guide the cock at the base while she rides. She has blue football socks pulled up to mid-calf. A classic black-and-white soccer ball lies on the grass next to them. In the background, a massive stadium filled with a blurred crowd of spectators, stadium lights and advertising boards are visible under a bright sky. Ultra-detailed skin texture, realistic sweat and skin sheen, perfect anatomy, cinematic lighting, photorealistic, 8k, sharp focus on the couple, depth of field blurring the distant stands.
