She lies back, her body trembling in anticipation. The machine hums to life, the dildo glistening with lube. She guides it to her entrance, feeling the pressure as it slides in. It's a slow, steady rhythm, filling her, retreating, filling her again. Her hips move in time, her breath coming in ragged gasps. She's lost in the sensation, her pussy clenching around the invading cock. She's close, her body tensing, her orgasm building. She cries out, her body convulsing as she comes undone.
