The sub's mouth is filled with a black ball gag, her drool dripping down her chin, as she kneels before Mistress. The dominatrix, in a corset and stockings, holds a riding crop, her eyes piercing. She presses the tip of the crop against the sub's gagged mouth, then trails it down her neck, between her breasts, to her stomach, making her squirm. The sub's eyes water as the crop snaps against her tender flesh, each strike echoing in the silent room. The mistress's face remains impassive, her control absolute, as she pushes her sub closer to her limits.
