It was all too obvious to tell that his mate was enjoying herself, bucking up to meet each thrust, their bodies colliding in turn. Riley hardly expected any less though, since it wasn't as if she had voiced any opposition to their mating. And though nothing would come of it, that did not stop the dog from trying, just like he had before.
A grunt escaped, mixed with panting as confusion blossomed. He could feel his knot being caught by her hand, and it added to frustration as he tried all the harder. That served to make it better for the both of them, but it didn't change anything until she decided that she was willing to give it to him. A strange situation, but one that the dog would roll with given the lack of alternatives at the moment.
His moves were desperate, almost frantic as he slammed in and pulled out, trying to get his knot in. And soon it was allowed, her assistance sliding the knot in easily with a wet pop, her walls clamping down on the knot and his length as he traded sheer force for speed, now rutting her as she came around his length, making it that much better as he neared his own climax. And soon enough he would give it in return, flooding her pussy with his cum, trapped by the knot. It was just as good as before, if not better. And it seemed that this was the start of a mutually beneficial relationship.
