Brunette riding guy with vibrator in bed scene

The girl has long dark brown hair and a slim frame, wearing red lingerie early on but quickly moving into full action. She starts lying on top of the guy, propped up on her arms in natural light, then switches to riding him with a vibrator in hand under warm lamp lighting. Her mouth is open, eyes engaged, clearly feeling it as she works the toy over him. Later, she leans forward, holding his arm, bending low in close angles that show her back and movement. They stay on the same bed the whole time, white sheets throughout, shifting from missionary to upright riding to bent-over positions. The camera stays tight, medium to close-up, focusing on her motions and reactions without pulling away.
