Penniless and with no prospects for marriage, twenty-one-year-old orphan Jemima Cooper has no choice but to take any work she can find, no matter how shameful. When she is sent by her employer to serve the Duke of Hillcrest, however, Jemima is surprised to discover that the handsome, eccentric nobleman intends to make her not merely his concubine but also his pet.
Within moments of her arrival at the duke's home, Jemima finds herself purring like a kitten as a collar is placed around her neck, and it isn't long before she is blushing crimson and trying to hide her helpless arousal as she is led through her new master's estate wearing nothing but a tail.
Though the duke soon proves more than ready to bare his beautiful pet's bottom and spank her firmly for any disobedience, his stern dominance only increases Jemima's need for him, and when he takes her in his arms and claims her properly it is better than she could have ever imagined. But will she always be just the duke's pet, or will he one day make her his bride?
