The submissive is positioned at his Mistress's feet, eyes closed, waiting for her command. She lifts her foot, revealing the sole of her flip flop, caked with dirt and grime. 'Clean it,' she demands, her voice stern yet laced with anticipation. He leans in, his tongue tentatively touching the sole, then working its way across, lapping up the filth. She watches, her breath hitching as he services her foot, her pussy growing wetter with each lick. His devotion is absolute, his tongue a tool for her pleasure, her feet his temple.
