Man and woman who drink horse stimulant creampies and sluts sex with divine Yuki

What will happen if you administer a "horse stimulant" developed for mating mares to the beautiful butt queen, Kami Yuki!? First, he gave the AD to take it, and after confirming that he would not die, he also administered it to her. The two dogs, who have grown so much that they have an abnormal metabolic effect, devour each other like livestock! What's more! They'll also be sent to fans' homes, covered in lustful juices even in their butts!
