The idea of trampling is hot. The visuals can be fantastic. It works both masochistically and psychologically. Yet somehow, whenever I try it, I struggle with it. I think that’s mostly because I’m afraid a rib is going to crack. I’ve got no natural intuition for the force they can take. It’s tough to relax into the moment when I’m picturing a trip to the ER and explaining why I’ve got heel marks all over my chest.
I suspect my fears are unwarranted when trampling is done properly. This article claims that a force of 3,300 Newtons gives a 25% chance of cracking a rib. That kind of force can be generated by a hard fast punch, but it’s a long way off the force exerted by the resting weight of a human. A 140lb domme would exert just 622 Newtons of force from standing on someone. Of course that’s only true when she’s stationary or when moving carefully. If she jumps then she’ll exert a very large force when she lands and rapidly decelerates. So if your domme wants to try that, I’d suggest telling her that Mr. Newton strongly recommends against it.
This fantastic trampling shot is from the twitter feed of Michelle Lacy. I love both the space she’s in and the bondage/trampling combo. If you’re interested in playing with her, she’s based in South Florida but does travel.
