Girl on top, guy lying down, no clothes

The girl is on top, grinding down on the guy who's lying flat on his back on a wooden floor. Both are completely naked. Her legs are spread wide, and she’s moving slowly, looking down at him. He’s shirtless, eyes closed, head tilted back, arms stretched out. The room looks like a home — wood floors, a white chair with some stuff on it in the corner, and a stone wall behind. It’s quiet, just the two of them. No music, no noise. Just the slow, steady motion of her hips. She’s focused, he’s relaxed. It’s intimate, raw, and real. No fancy setup, no costumes. Just two people being physical with each other in their own space.
