In the dimly lit dungeon, the mistress' heels click on the stone floor as she approaches her trembling, collared slave. She commands the babe to kneel, presenting her submissive mouth. The mistress' thick, glistening pussy hovers inches from the babe's face, the scent of her arousal filling the air. The mistress grips the babe's hair, forcing her to engulf her, teaching her the pleasure of being used, of being a mere vessel for her mistress' orgasms. The babe's eyes water, her gag reflex triggers, but she endures, eager to please her mistress, to become the ultimate femdom slave.
