Military Girl Ballbusting You in White Dirty Combat Boots

I used them a couple of times before performing this session, which ended up brutally... The good thing about low-heeled boots is that are extremely easy to use: you can walk, march, run, jump, full weight, basically anything! Meanwhile, heels require more attention as very dangerous, and you know why. The problem with these combat boots comes when there's a mistress like me wearing them, with a lot of experience in crushing small meats and nuts! You might expect some crushing and trampling as usual, but those who know me well enough may remember that I try to push my slave more with every new session recorded. By "push" I mean being more aggressive and trying to destroy his testicles to the point that he won't feel my weight anymore. Probably this session added a new pain layer for the slave, indeed now he can resist stronger kicks and heavier crushes. If you were in him, do you think you could resist? Or would you end up crying and begging for mercy?
