It's one thing to slide in a butt plug and enjoy the feeling of having your ass stuffed. It's another to "expand" on that (Hahah), and use the attached hand pump to inflate the butt plug and stretching the anal cavity. When you're done with the inflation, a quick release valve releases the pressure.
Let the Anal dilator do the job, expand the hole.
