I wanted to try this experiment for a long time and, also thanks to the new board, I finally made it! Crushing cocks and balls while wearing painful boots is something that always turns me on, but it's not easy to crush everything properly sometimes. I decided to crush his cock full weight under a plexiglass panel so that I can see what would happen when my weight fully stood on it. Then why not march a little bit? And what would happen if only the balls were crushed by my weight, slowly increasing it by walking towards them... there was only one way to find it out! I went through a few phases: 1. Preparing both cock and balls for what was going to happen by slapping, kicking, and squeezing everything under my soles. 2. Crushing both cock and balls under the panel, walking, marching, and taunting a little bit... 3. Crushing only the balls, so that the whole pressure was only on those poor little grapes. 4. Finish the slave by draining the damaged testicles, making him cum on my boots!
