A muscular man positioned behind a woman in a doggy-style position next to a canal in a Venetian setting, engaging in vaginal sex. The woman is on all fours with her knees bent and hands on the ground, her back arched to emphasize her hips. She is wearing a skimpy bikini top that accentuates her cleavage and a tiny thong bikini bottom, highlighting her exposed buttocks. Over her bikini, she wears a transparent mesh cover-up, adding a slight touch of elegance. The man is kneeling behind her, shirtless, with his toned chest and abs visible. His hands are firmly gripping her hips, while his hips move rhythmically as he performs vaginal penetration. Her legs are long, smooth, and tanned, with her toes resting on the ground for support. The lighting is natural, with the sun highlighting their skin and muscles. Her face is perfectly visible in profile, showing sharp facial features and well-defined eyes. The background shows the canal with a small white boat and classic Venetian architecture, emphasizing the intensity of the scene. masterpiece, photorealistic, ultra-detailed, 8k resolution, HDR, ISO 100, natural lighting, vibrant colors, minimal noise, perfect composition, sharp focus, soft shadows, perfect exposure, high contrast, slim waist, toned figure, smooth tanned skin, long legs, exposed buttocks, muscular man, toned chest, abs, strong arms, firm grip, skimpy bikini top, tiny thong bikini bottom, transparent mesh cover-up, red open-toe sandals, Venetian canal, classic architecture, small white boat, calm water, sunny day, vaginal penetration, doggy-style position, rhythmic hip movement, arched back, intense interaction, perfect facial features, well-defined eyes, sharp profile, smooth skin
