Special type of BB

I think it's a special type of ballbusting or maybe a combination of weight fetish and ballbusting: When l lie on the ground and a woman steps on my ass with her full weight, squeezing my balls with her entire weight. She presses my balls against the ground by standing on my ass.
It's a little bit frightening (because you don't know how much weight your balls can take) and exciting at the same time...

What are your experiences with this type of ball squeezing...?? What's the maximum weight of a woman your balls accept?
