When submissive minx Penny Birch finds herself chastised by the matronly Marjorie Burgess at a dinner party for university colleagues, the situation is so outrageously old-fashioned that Penny assumes the older woman is playing an erotic game with her. Penny is doubly humiliated when she is caught gratifying herself over the experience, only to find that Marjorie was entirely serious. Kinky counsellor Gabrielle Salinger comes up with a face - and job - saving solution, but can Penny resist being drawn even further into Gabrielle's circle of perverted associates?
