Isabella want to choose one pair boots and uses her slave for helping her which one she should take.
He has to put her on the nice westernboots with small heels, then she orders him to the ground.
He knows what's coming and want resist, but with some small kicks he is definitively on the ground and she steps on him and nails him down.
She walks with small steps on him, puts her weight on the heels so the can sink deep in his flesh.
She let him kiss the sole of one boot while she stands with the other on his chest.
Then she steps on his head and face... a nice but painful treatement under a nice lady with nice boots...
