This is a well trained dog with an experienced pet lover. She knows exactly what to do to get him interested and when she jacks him you can tell he enjoys it. He jumps right up on her back as soon as she turns around and although we don't see him enter her we can hear her moan as he drives himself into her. he drives her hard as she moans in delight.She enjoys him immensly but we never see his knot or him pulling out of her. I would have loved to see him tie in her and hear his panting as he unloaded his seed into her womb. When he was done a nice big red knot pulling out of her wet dripping pussy would be a big turn on.
