A hyper-realistic, highly detailed erotic scene in a large open-air football stadium during daytime. Camera view from behind the woman. A beautiful young woman with long wavy blonde hair, fair skin is riding a man in classic cowgirl position on the green grass pitch, facing him. From this rear angle we see her large, round, firm, pale ass and the thick, veiny erect cock deeply inserted into her wet, detailed pussy, labia stretched around the shaft. She is squatting and bouncing on him. One of her hands reaches down between her legs to hold and guide the cock at the base. 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 partially visible from the side. 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 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.
