As a ballbusting video connoisseur and frequent ballbusting sessioner I can share a few thoughts.

1) some of the videos are “fake”. I won’t name names, but if you watch closely you can see the foot doesn’t actually hit where the balls are. If you follow the WWE at all, there’s a video of Paige on one of the sports talk shows demonstrating this. The WWE practically invented the fake ballbust!

2)Some guys have amazing tolerance. Many of these guys end up making ballbusting videos

3)balls can take more abuse than most people think. Trust me on this one, lol

4) Many experienced Dommes are good at watching out for injuries during a session and I think know how to hit in a relatively safe way. But I’ll defer to the Pros on this one
