Students of Submission. An erotic novel

Sally becomes one of eight university students hand-picked to participate in a financially rewarding social psychology experiment. At a secluded mansion, she meets the imperious "Director", Jane, who is to subject them to a series of challenges, more sexual than social. She realises she must hide some details of her recent history from Jane, but can she do this in the face of the increasingly perverted violations which rob her of will, as she succumbs more with each deliciously inventive pleasure, increasingly in thrall to the dominant older woman and her well versed staff?
