He reached one arm behind her to grab her bound forearms as leverage while the other hand hooked into the ring at the front of her collar, pulling her down to him in a series of hard thrusts. Just as she was about to tip over the edge, he kissed her as she cried out against his mouth as the waves of pleasure overcame her, her hips jerking and spasming against his lap. He pulled back to let her catch her breath, and she immediately smiled, leaning forward to press her lips against his once more. When he reciprocated, she sighed, kissing him languidly and humming in contentment. "Thank you, Master."
