There's a lot to work with here, these fat, full balls look like they'll take a lot of painful pressure to get them flat. I methodically kneed them, ruthlessly pushing the soles of my feet into the sensitive center of his nuts. Simultaneously holding them in place while controlling exactly how much pressure they deserve. I ignore his wiggling and moans as he tries to escape his fate, I'm going to flatten his balls in the most delightfully drawn out, excruciating way possible, while he watches on in horror.
