The shadowy hound let out a victorious howl as the giantess admitted defeat, he reduced the swell in his knot, but he didn't remove it, she was a tight fit to begin with, but this made it so that he had to fight to get in and out of her. He set his two paws just inside her armpits and started to thrust at an even more furious pace. The once gunshot loud noise of their connection became a wet and lewd smacking noise as his massive cock struggled to get in, before getting the not in and slamming the head into her womb, all the way, made easier by her own fluids and his previously spread seed. He set his snout upon her breast again and asked her with an evil chuckle, "Ohoho! My giant slut you, you actually want to bear my pups, all of the<em>thousands</em>of times I require. Please, don't hold back<em>tell me just how much you want me to continue, even as my seed sits firmly in your begging pussy!</em>"
