The room is filled with the scent of damp earth as the Mistress, clad in black stockings, commands her slave to his knees. She lifts her feet, the soles black with dirt, and presses them onto his face. He moans, inhaling the rich, earthy aroma, his tongue darting out to lick the gritty surface. She moves her feet, guiding him, her heels digging into his scalp as she uses him like a human brush, cleaning her stockings, leaving trails of mud and saliva on his face. His body responds, his cock straining against his pants, eager for her attention, but he knows his only purpose is to serve her feet.
