Hentai, detailed anime style, 2D, bright colors, soft shadows, clean lines. A clearing at night, a starry sky, dark trees in the background. A classic UFO with yellow lights around its rim stands on the grass, and two more UFOs are visible in the sky with bright yellow portholes and a blue cone of light shining downward. In the foreground is a blue-skinned alien girl with a large, smooth head, enormous yellow eyes without pupils or whites, a tiny nose, and pointed ears. She is completely naked, with rounded breasts, and is kneeling on the grass. She is sucking the penis of a naked man standing to her right, (only part of his body is visible), . The grass is green, the lighting is nighttime, with soft blue and yellow light. High detail, masterful execution, top quality, hentai, NSFW.
