Servant's fantasy

She speaks softly as she waits. 'I want to give my Master everything he needs.' She bends forward and shows him the firm curves he likes. He steps behind her. His hand grips her waist. She feels the size of him against her skin. The heavy weight presses at her entrance. She breathes out and relaxes. Slowly, carefully, he pushes inside. The stretch is deep and steady. He moves with purpose. She takes every inch. Her body tightens around him. He grips her harder. The rhythm builds. She moans softly each time he fills her. Sweat beads on her back. She stays still and open for him. Every thrust makes her shake. He pulls her closer and drives deeper still.
