continuous cocksounding and urethra stretch with machine fpr long time Part 4

In Part 4 my urethra torture get the next level. I let the cocksounding machine work continous work for a long time with my 13mm ribbed cockplug. It was very extreme for my urethra, but the machine knew no mercy. Can you count how often my urethra was fucked in this part and overall at the end? This Part was very heavy but I think my urethra can take more and longer penetration... Please watch my last Part :-)
