Bound and helpless, the teen's cries echo through the sterile, white-walled room as the therapist begins her anal treatment. He starts with a thick, black plug, stretching her tiny asshole until she screams. Then, he replaces it with his rock-hard cock, pounding her relentlessly. Her face reddens with each thrust, tears streaming down her cheeks as she struggles to take his massive girth. The therapist, unmoved, continues his brutal therapy, his balls slapping against her ass until he finally pulls out, covering her face with a torrent of hot, sticky cum.
