It's all fun and games until you have a 600+ lb woman bouncing around on a tiny ball that's resting on your chest. The moment the weight drops on you, though, you know in a hurry that it's a very serious place to find yourself. Watch BMK abuse one of our tiniest seats with her massive body. At one point she leans her full weight into his throat and pushes him to his limits. At another point she facesits him full weight long past the point of him tapping. He struggles and struggles but there's one overwhelming fact when it comes to Kat... she's going to get off of you when she damn well pleases... and not a moment sooner.
