Her slave already has some hard marks from former trampling, and that's the best condition for Lisa to test her spiky steel high heels with a lot of fun seeing her slave suffering under her trampling feet! And his screams definitely won't stop her, she has no mercy. He shouldn't lament this, 'cause it's a privilege to serve her! After she had a bunch of fun drilling her spikes in his oppressed skin, she takes off her shoes at last. But torture isn't done yet!
