In a private dungeon, a submissive male slave, hands bound behind his back, is ordered onto his knees by his stern mistress. She presents her bare feet, soles facing him, commanding him to worship. He obeys, gently kissing, licking, and sniffing her toes and heels, his eyes closed in reverence. She moves, grinding her soles onto his face, smothering him in her scent. He gasps, thrilled, as she commands him to open his mouth, inserting her toes, using him as a human ashtray.
