The main theme of this book concerns a man who dreams of speaking to Venus about love while she wears furs. The unnamed narrator tells his dreams to a friend, Severin, who tells him how to break him of his fascination with cruel women by reading a manuscript, Memoirs of a Suprasensual Man. This manuscript tells of a man, Severin von Kusiemski, who is so infatuated with a woman, Wanda von Dunajew, that he asks to be her slave, and encourages her to treat him in progressively more degrading ways. At first Wanda does not understand or accede to the request, but after humouring Severin a bit she finds the advantages of the method to be interesting and enthusiastically embraces the idea, although at the same time she disdains Severin for allowing her to do so. Severin describes his feelings during these experiences as suprasensuality. Severin and Wanda travel to Florence. Along the way, Severin takes the generic Russian servant's name of "Gregor" and the role of Wanda's servant. In Florence, Wanda treats him brutally as a servant, and recruits a trio of African women to dominate him. The relationship arrives at a crisis when Wanda herself meets a man to whom she would like to submit, a Byronic hero known as Alexis Papadopolis. At the end of the book, Severin, humiliated by Wanda's new lover, loses the desire to submit.
