No. Where do you guys see knotting? He just put his enormous di** completely in and reached the womb. He is pressing his di** through the cervix (my interpretation). You remember when they did it at the end of the season? There he did the same and Taejou himself said, he reached the womb, the place where babies are made. And the knot is always at the base of the di** and you can't see something like that in the pictures.
