LadyM has her slave on some stools, his head is bendt back over the edge, so his throat and larynx is fully exposed, right for some torture ;-)
She steps over him and drops down on his belly, giving him an idea how he will be crushed in the next minutes.
She bounces up and down and moves with each jump a little bit foreward to his throat.
Once sitting on his throat she don't stop bouncing, she wants to break him.
Ocassionally she turns around and rides his throat in reverse style.
Don't try this at home, a sore neck for some days will be guaranteed... or may be a broken one?
