Stepmom agreed to back rub but pussy needed warming up too

A woman in a black robe lies on a bed scrolling her phone before switching to lingerie. A man massages her back and hips as she lies prone, then shifts to straddle her from behind. She reacts with surprise and pleasure as he moves his hands lower, eventually lying flat while he continues touching her intimately. The scene ends with her kneeling, head bowed, fingers pressed together.
