Mistress Geneva, a stern British dominatrix, welcomes her latest clients, a timid couple seeking her humiliatrix expertise. She begins by dressing the husband in lingerie and heels, transforming him into her sissy. The wife watches, her arousal growing as Geneva orders her husband to serve drinks, crawling on all fours. Geneva's voice is a whip, her words stinging as she belittles him, making him call her 'Mistress' and his wife 'Goddess'. The wife's humiliation turns to ecstasy as she's made to sit on her husband's face, his tongue dutifully pleasuring her while she watches Geneva tease her cuckold with a vibrator.
