The cuckold, bound and gagged, watches as his wife, now his mistress's plaything, sucks another man's cock. His eyes widen as she takes it deep, her moans echoing in the room. His femdom, a stern beauty, watches him, her voice a low purr, "You like seeing her like this, don't you? She's learning to please, while you learn to obey." She strokes his hair, her nails grazing his scalp, as his wife's body convulses in orgasm. The cuckold's cock throbs, aching for release. "Not yet," his mistress whispers, "You'll cum when I say so. Now, clean her up."
