Earth has fallen to the power of a sadistic race. The innately cruel and beautiful beings extract exquisite pleasure from punishing and humiliating their possessions, and they enslave humans to serve them as maids, pets, ponies, furniture, decoration, or in any other way they see fit. Theresa is one such captive. Caught and branded by one of their Generals, she is taken off world to his family estate. Upon arrival, she is trained and made to serve the dominant fantasies of the occupants. His nubile daughter takes special interest in seeing Theresa suffer, as does a handsome groom that wants to turn her into a prize filly, but that becomes the least of her worries when the master of the house returns from war to sample depraved delights with his latest trophy.
