Mistress Mae instructs her slave to lay down on the bed. Using her smaller ribbed urethra stretcher, she slides it in and out of his penis making him squirm. Once it is nice and stretched out, she grabs the bigger one to try. She gets the tip of the big one in making him squirm, but the rest is still a bit too big to fit. She continues to push the large one in at the tip for a while until she decides to stop for the day.
