I came but she keeps shaking — was that her orgasm?

A tattooed woman in a light blue bra rides a man in bed, her legs spread wide as he thrusts. She moans with eyes closed, gripping his hips while he holds her ass. Later, she lies back, legs up, as he enters her from behind, her body trembling with each movement. The scene is intimate, lit by bedside lamps, focusing on their physical connection and her visible pleasure.
