When Doctor Damian Thatch's sadism is extended to his stepsister, Edith, in a taboo encounter on her visit to his London consulting room, it awakens her desire to treat her maid in a similar manner.

Edith’s maid, Annie, while otherwise excellent in carrying out her duties, is ill tempered and disrespectful, so Damian has Edith bring her to him for a consultation. His suggested cure for such behavior in a maid is spanking and birching, which he demonstrates to his enthusiastic stepsister.

Edith takes particular delight in the control she has over Annie when she strips her maid for punishment, but she soon realizes that she wants more. Rather than simply punish her maid, Edith wants to take her as a man might. But the only female body she has ever touched has been her own, and what if Annie resists such treatment from her mistress?

Annie senses the sadistic urges developing in her mistress, and is afraid that Edith will be severe in delivering punishments. She appeals to Damian for a medical solution to help control her behavior, but a maid cannot afford the services of a London physician. Damian, however, tells her of an alternative form of treatment that a mistress might perform on her maid, setting up Edith's first time lesbian encounter with Annie bound and spread on Damian's consulting couch.

This is an adult only work of Victorian erotica fiction involving bondage, spanking, buggering, sadism, masochism (BDSM), and first time lesbianism.
