In a private dungeon, a thrall is introduced to his mistress' unique fetish. She presents her feet, encased in sheer stockings, and he's to pleasure them. He takes her heel in his mouth, sucking gently, his tongue exploring the texture. She guides his head, her foot rubbing against his straining erection. He's to give her a sloppy, thorough blowjob with his mouth, but only with her feet. His dick aches, but his mistress' satisfaction is his only goal.
