An 18-year-old blonde woman sitting nude on a white stone bench under bright sunlight, her glowing tanned skin glistening with water and watermelon juice. She holds a large slice of watermelon, alternately sucking it with glossy, inviting lips and using it to penetrate her vagina. Her slim yet curvy figure features a very narrow waist, wide hips, large round and firm breasts, and long toned legs. Her youthful and seductive face has piercing blue eyes, thick lashes, a small upturned nose, and full glossy lips, with a playful and sensual expression. She leans back slightly, one leg bent and the other extended, her hands gripping the watermelon slice as juice and water drip down her arms, thighs, and chest, highlighting her curves. The background shows a minimalist outdoor setting with clean white walls casting shadows, a potted green plant, and light gray concrete flooring. Bright sunlight creates soft highlights and shadows, adding depth and warmth to the scene. The image is photorealistic, high resolution, HDR, ultra-detailed, with smooth textures, sharp focus, and professional outdoor lighting, captured in 8k resolution., <lora:Microwaist_XL_v01:1.5>, <lora:breasts_slider_v10:1.5>
