With Master's eyes not on her, the submissive takes control, her hand wrapping around her throbbing cock. She strokes it slowly, feeling the veins pulse with need. She spits in her hand, lubricating her firm grip, her thumb rubbing the pre-cum into her skin. She picks up the pace, her hand moving faster, her grip tightening. She can feel her orgasm building, her balls tightening, her breath coming in short gasps. She leans back, her hand moving furiously, her body tensing, and then she comes, ropes of cum shooting out, coating her hand and belly, leaving her spent and satisfied.
