He began to slowly massage my ass cheeks, his thumbs teasing my anus. This felt good, really good. He would run the tips of his thumbs around the edge of my anus, then tentatively began to explore the opening, inserting only the tip of a thumb, or was it two thumbs? I was really getting turned on. My next action surprised me… I arched my back and pushed my ass into the air. Robert took the hint and massaged even deeper. I felt him reposition himself, now at my side, facing backwards.
