missy knew that barking was the price to be paid in order to avoid being sent away from the very brief time the dominant gentleman would be close enough to allow missy to be physically with him.
missy managed to overcome the fear of loss of humanity, and to express the dedication of every aspect of physical and emotional self to the service the dominant gentleman preferred.
missy managed to bark, never finding it easy to do, but becoming better at it as the practice continued throughout the night of service to the dominant gentleman.
because missy is a pain slut, missy pays a physical price for service. the dominant gentleman has pierced each of missy's nipples once, and has clamped them many times. when missy had served for several months, during which missy had begged the dominant gentleman to pierce her nipples as a symbol of his ownership, the dominant gentleman agreed. missy was thrilled to have a permanent expression of her service and dedication to the dominant gentleman. missy relives the nipple piercings each time the nipple hardware is put into place, and looks upon the dominant gentleman's barbells as a concrete expression of her dedication to and love for the dominant gentleman.
