When Stephen Stanbrook comes to consult therapist Gabrielle Salinger about his yearnings towards sexual dominance, her girlfriend, Poppy, is fascinated. Determined to find out more, she traces his exploits on the net as he seduces two young submissives, Nicola and June, known in the SM community as Knickers and Boots. Before long she’s involved with him, and them, all in uniform as they’re put through their paces in rural Dorset. Meanwhile, Fat Jeff Bellbird is pestering Gabrielle in the hope of something yet more perverse.
