Man and dog play involves a diversity of poses

A dude and a dog familiarise with every other, and start to explore every other's weenies and butts. This familiarity with every other in a short time turns to intimacy, with the dog mounting the fellow. They then proceed throughout a wide diversity of positions, including from behind, a-hole to butt, and wang inserted into gap. The poses change continually, including a scene where the dog is then screwed by the man's throbbing, hard cock.
