Swinging too hard

... hearing. My continued grunting was only matched by the loud panting of the beast above me. Unintentionally, my sphincter kept milking the huge cock while it was sawing through my anus. This was driving Bernard even higher state of frenzy. He was ready to start insemination of the bitch but before that, there was one technical matter to be taken care of.

I felt the added pressure at my anal opening and this forced me out of the blissful state I was in. The pressure was becoming somewhat painful. "He cannot get any bigger, right...? My ass cannot take much more.", I thought while stressing about the situation. "Maybe he is preparing to cum?", I thought. Then I remembered one nature documentation I saw years ago. Some animals ensured the insemination of bitches with various methods. With dogs, something called a knot was going to form the base of the cock. "Oh please god no... It will tear my ass".

The rock-hard cock did its part and applied enough force by pistoning in and out through my anal opening. The knot kept hitting my anus which blocked the final access for the Bernard. He thrust harder and harder at the lubricated entrance of my rectum. I felt my sphincter expanding slowly when the "gatecrasher" kept slamming against my anus. The wild hammering continued harder and harder until my ass finally gave in. The knot smashed into my bowels with force. The cock pushed deeper than before, and my ass was filled to a point that I did not know was humanly possible. I had thought that knot was at the base of the cock but clearly, I was wrong.
