Empty balls are the most fun to punish. Nothing I like more than the look in their eye when their testicles flatten. Watching this slaves globes compress after I've emptied his sperm is almost as much fun him as it is for me! Gagged, he hyperventilates as his nuts collapse in the testicle crusher. I inflate the gag and watch him sweat as the balls compress. Ballbust handjobs always bring a smile to my face.
