He lubricated it well, even fully inserting his finger. I thought I could smell Vaseline. I felt the gland push against the tight muscle. The end of his member was soft; but as he began to force it the anus was worked open, just a little, then a little more. His action was uncomfortable. The tip popped inside of me, then the discomfort eased slightly. Gently, but firmly, he penetrated further. That hurt! It was like I was passing a hard turd. He stopped. I moaned. The pain eased. Further, the full bore was in me. The feeling of my shitting was overwhelming as I felt his hips against the soft cheeks of my buttocks.

It was driving me wild. I felt like I was going to cum again. Then he froze with it fully inserted. I felt his warm cum surge into my rectum. Now he was groaning. I was panting. Why? This was stupid, his dick was up my ass. I could hardly stand it. His erection began to ebb. My anus began to close around it as it weakened. He pulled it out, quietly saying, “I needed that.”
