Mistress Kelly tortures and humiliates her willing blond submissive in a pedestrian opening scene unrelated to the story. Melanie discovers Kym and her lover in their messy apartment, so she takes them to the dungeon to teach them a lesson. Kym's lover turns on her by helping Melanie strap her down. Melanie, with an almost sadistic quietness, lashes Kym with a variety of whips and attaches clothespins to her breasts. When she lets Kim up, Kym turns the tables on both her captors and authoritatively gives them a taste of their own medicine. Well directed action, with interesting comments sprinkled throughout the domination scenes make Roommate Humiliation a must-stock tape.
