Jane has new shoes with high heels, she wants to know, how is the walking on different surfaces.
The most important test is walking on soft flesh... Slave!!
She steps on his belly, letting her heels sinking in the soft slave.
The she watches the imprints... the shoes are new and have sharp edges,... the imprint could be deeper.
So more steps are necessary, also steps on the head... heels vs. skull is an interesting combination.
And for some breaks, the groin area also need to be trampled with these high heels.
