The room is filled with the scent of leather and the soft hum of a machine. A woman, a dominatrix, sits on a throne, her legs spread, a man kneeling between them. She grips his hair, pulling his face into her crotch. "You're going to lick me until I come, bitch," she commands. He obeys, his tongue flicking against her clit, her juices coating his face. She grinds against him, using him for her pleasure. When she's satisfied, she sends him to fetch her a drink, his body trembling with anticipation of her next command.
