Heavy Crushing or Painful Bootjob, Perfect Painful Tank Heels

The story behind this session is a bit complicated, but all you have to know is that it has been recorded three times in 2 days... you can only imagine the slave's pain. If you are wondering why, the reasons behind it are purely technical, but the show must go on! At first, this pair seems a normal one with cute white leather, but every time it gets proven wrong: the tank's hard-shaped soles are extremely painful, as the gap in between treads' layers is quite big and made out of strong rubber, not soft at all. When crushing down a poor cock or the ballsack, the pressure concentrates on small areas, basically a third of the whole sole, meaning that the slave will feel three times my weight or any pressure applied. It's pure pain, like it or not, and once you're down there isn't much to do if you not finishing quickly. I also used the plexiglass again for the first portion of the video; I feel like I should use it more often so that I can train my slave to have a higher pain limit...
