Roommates continues with introducing Diana Black (Melissa Jacobs), the best damn dominatrix around. She explains that her roommates were the worst and shows you why. Her roommates were jealous of her success as a dominatrix and wanted to ruin her reputation as one tough bitch, so they tied her up and gagged her, leaving her to struggle while they filmed her. The two ladies knew if any of Diana's clients were to see her helpless and gagged, struggling on the floor, it'd be detrimental to her business.
