I eagerly agreed and he moved closer to the wall and rolled onto his side to face me and I lay on the table facing him cock to mouth. He took all of ...e into his mouth at once, but I had a saw jaw from the work I was doing for the past few minutes so I used my hands and alternated with my mouth. This went on for a couple of minutes, then someone knocked on the door. It was the doctors receptionist, the doctor took me out of his mouth and told the receptionist to come in.
