The submissive, bound in a tight hogtie, squirms with desire as his Domme strokes his aching cock. 'You want to cum, don't you, pet?' she taunts, her voice laced with power. He nods eagerly, his eyes pleading. 'Then make me a promise,' she demands, her fingers tracing the length of his shaft. 'What promise, Mistress?' he gasps. She smiles, her eyes gleaming with dark intent. 'Promise to eat your own cum from my cunt. Lick it all up, every last drop.' His breath hitches, his heart pounding in his chest as he agrees, 'Yes, Mistress. I promise.'
