Prodigal Mistress. Submissive Cynthia, #6

Cynthia was sad. She was a submissive woman who needed a firm hand in her life, and hers had recently walked out the door. She knew it was her fault that her cruel and sadistic mistress had left her. She hadn't been obedient enough, nor had she been grateful for the punishments she had so richly deserved. But Cynthia was willing to change. She would do anything to get her lover back. No act was too depraved, no punishment too harsh.
Anything that was asked of her, Cynthia would do.
