The guy is mounting his pregnant bitch. It is clear that she is not minding at all that he penetarates her and it is evident that this has not been the first time. His dick is about the right size for her and someone with a bigger dick would have struggled to get it in. Her looking back at him indicates that she enjoys it as well. I love the fact that we start of with a far off shot, showing the bitch and also allow us to have a look at her facial expresion when her lover makes love to her. The fact that it was shot in daylight also adds to the quality of the movie. It is a pity though that sound quality is not good, but I nevertheless really enjoyed the video.
