Brunette and guy on couch, she's all over him

A brunette woman is on top of a shirtless guy who's sitting on a couch. They're both naked and she's grinding down on him, hands on his chest and hips. He's looking up at her with his mouth open. The room looks like a living room with blue and red curtains, a window behind them, and some clothes on the floor. The vibe is casual and intense — no fancy setup, just two people being physical. She’s got dark hair and he’s balding. They’re both focused on each other, not looking away. The couch is dark gray, and there’s a green shirt and red blanket nearby. It feels like a real moment, not staged. No music or fancy lighting — just the two of them and the room around them.
