Bound and helpless, the slave is commanded to cum on cue, her Mistress's voice echoing in her ears like a cruel metronome. As she reaches her climax, she's ordered to taste her own filth. She hesitates, but the crop's sting on her bare ass spurs her on. She tentatively licks her fingers, her face twisting in disgust, yet her pussy throbs with forbidden lust. Her Mistress watches, amused and aroused, as the slut follows her every humiliating command.
