Carmen Rivera, the femdom queen, indulges in her favorite pastime - fisting. Her slave, a muscular, eager-to-please man, is her canvas today. She oils her hand, generously, the scent of jasmine filling the room. He watches, cock throbbing, as she lubes up. "On the bed, legs up," she commands. He complies, ass exposed, ready. She teases him, fingers tracing his hole, before plunging in, one, two, three, four, her entire hand disappearing. He gasps, moans, begs for more as she pumps, her other hand stroking his cock, bringing him to the edge, then backing off, drawing out his ecstasy.
