3-1/2 inch plug gapes the ring

Taking on the 3-1/2 in x 6 inch long cylindrical plug. Easing blunt fat end past the anal ring muscle, really wrecks the asshole. Once past the rectum the whole rectum chute is expanded to the max and held for a long period of time. Then using a rubber mallet to smack the end every minute to really nail the analring muscle and rectum, after 1/2 hour of punishment my asshole ring muscle hangs non-closing on pull out.
