extreme cocksounding and urethra stretch with machine Part 1

I decided to strech my urethra in one day from 13mm to 14mm. My aim is, to get my litle finger easy down my urethra. I use many itims. The best is my cocksonding machine. The machine works continuously without mercy. Can you count how often my urethra was fucked in this part and overall at the end? I hope, that I have succes at the end... ;-) This is Part 1 of my session.
