In a private, furry fiasco, a submissive pup, eager to please, secures a massive horse-dildo to his waist. He barks in anticipation, lubing up the colossal toy before presenting his ass, ready for penetration. He whimpers as he slowly sinks onto the beastly length, his tight hole stretching to accommodate the girth. With a collar around his neck, he eagerly rides, his hand working his leaking cock. The room fills with the sound of his wet, sloppy fucking and his own delighted yips. He moans as he feels the first hot spurts of his own cum mixing with the lube, filling his eager ass.
