Cybill Troy has her slave locked in the stocks and ready to be fucked by Mistress An Li's big black strapon cock. Cybill wants to be sure that while he's being fucked, he doesn't enjoy a moment of it, so the sadistic Mistress whips and straps his ass and back while he's anally destroyed.
When the Mistresses has successfully broken him, inside and out, he's to his knees to kiss their asses and thank them for the humiliating treatment, before having An Li's cock shoved down his throat for cleaning and being locked back into his cage until they want to terrorize him again.
