Two people having sex from behind

The camera is right behind them, showing the rear view of both people. One person is on top, grinding down into the other who's lying on their back. You can see the skin and the movement as they shift. The lighting is dim, maybe from a lamp or window, and the background is blurry but looks like a bedroom with some furniture. There's no music or talking, just the sounds of their bodies moving. It feels raw and real, like you're right there watching them. No fancy staging, just two people getting it on. The focus is tight on the action, so you can see the details of their skin and how they're positioned. It’s not a big production, just straightforward sex happening in a private space.
