A brunette dominatrix, her hair pulled back into a stern bun, oversees her blonde slave, bound and gagged. The blonde's eyes widen as the brunette approaches, a riding crop in hand. The brunette trails the crop down the blonde's body, across her heaving breasts, over her flat stomach, and between her legs, making the blonde squirm. "You will learn to please me," the brunette commands, her voice like velvet and steel. She begins to strike, not harshly, but firmly, each blow sending shivers of pleasure and pain through the blonde, who moans around her gag, eager to please her mistress.
