"Very well, then. You'll need to show me how much you've learned. Begin by admiring my perfect, immaculately manicured feet. Tell me how much you love them and want to serve them."
She splayed her nails wide, pointing them at him. He knelt, his eyes never leaving her feet. "I love your feet, Mistress. They are perfect and I long to worship them."
"Very good. Now, use your tongue to taste each of my toes. Start with the smallest one and work your way up."
His tongue flicked out, tracing the arch of her foot before delving between her toes. He kissed each one, savoring the salty taste. She moaned, her foot moving in a slow circle.
"Now, suck on my toes one by one, and be sure to put some tongue between them for extra pleasure."
