The last time that I ass trained my slave, I decided to be kind and let him choose which dildo would fuck him in the ass. He chose one of the biggest ones, which pleased me, but maybe it wasn't a smart choice. He struggled to take the huge fat cock into his tightly stretched asshole. And when I started thrusting the monster in and out of his tight hole he started whimpering and whining like the bitch that he is. Maybe next time his eyes won't be bigger than his asshole.
