Fucking under sexologist’s watch to diagnose my erection issues

A woman with red hair performs oral sex on a man while another woman in a white shirt observes, takes notes, and adjusts the red-haired woman’s clothing. The scene shifts to the man penetrating the red-haired woman on a desk as the observer watches closely, sometimes touching her. The setting is an office with bookshelves, and the observer appears to be guiding or evaluating the sexual activity as part of a session.
