Erica's eyes flash with sadistic glee as she orders you to service her feet. You hesitantly comply, your mouth wrapping around her big toe, your tongue swirling around it. She moans in pleasure, her foot twitching in your grip. You move on to the next toe, then the next, each one slick with her juices. She guides your head, her foot pressing against your tongue, your lips, your chin. You can feel her pleasure building, her foot trembling as she nears her climax. "Don't stop," she hisses, her voice ragged with desire. You obey, your mouth working overtime, your jaw aching, your lungs burning, but you wouldn't dare stop. Not until she's had her fill.
