Continuing with training her slave, Miss Wildfire has her slave locked into a humbler.

This means she can create so much extra pressure as she stomps and kicks the balls with her nylon feet.

She can create so much pain with so little effort, putting the slave in so much pain as she stands on the balls.

The sadistic blonde Mistress is so satisfied by how much pain she can cause.
