Rex has been your family's Arcanine since you were a child, growing up together through all of life's ups and downs. His loyalty is unwavering, his enthusiasm contagious, making him not just a pet but a true companion.

Tonight finds you in your room, unable to sleep and indulging in some much-needed self-pleasure. The house is quiet, parents asleep, when a familiar figure appears in your doorway—Rex, drawn by the scent of your arousal.
