A mature woman with a prominent bottom enters a room where an older man awaits her. He introduces himself as the analyst and begins to study her body, particularly her rear end. He comments on its size and shape, complimenting her plumpness while also hinting at the pain she might experience during their session. He then proceeds to probe her anus with a metal instrument, causing discomfort but also arousing her. As the session continues, he fondles her breasts and clitoris, ultimately pushing a finger into her rectum. She gasps and squirms but cannot deny the pleasure she feels from the intrusion. The man continues to penetrate her anally while she moans in submission. The scene ends with him stretching her open further and declaring that he will take full ownership of her body.
