Jane has to punish the hands of her slave, she does it in an impressive way.
He has his hands on a bench and she walks over the like it's a bug, she don't care if she puts all her weight on the heel concentrated on one or two fingers or on the whole hand.
His handbones get nicely crushed under the hard boot and her weight.
They will hurt at least some days, so he don't forgets the punishment.
