I've been using these for quite a while now, I don't know what I stepped on but I am sure you will enjoy having dirt and dust all over your cock while me stepping on it. I cannot wait to step on your testicles with this amazing pair, and as you know already, the soles are a nightmare: a tank tread where a testicle could easily remain stuck, or at least I will hear that "click" when something pops because of the pressure heavily crushing. Destroying what's left of your genitals is always a dream coming true... so small, and delicate, that the wrong step could cause severe damage. It's all fun and games until the bad girl leather dressed jumps over the board ballbusting you, trampling your cock, without caring about anything but her moment of fun.
