Erina wants to train walking on a runway - of course its going to be a human runway. Shes wearing vapid boots and walks all over her slave, from his gams, over his groin and chest up to his face! The boots may be vapid - but the feet hard and hurts the slave as she attempts to balance on his uneven assets - especially when she steps on his face and shifts his skin under the hard rubber foot. Later on the slave has to take her boots off and she tramples him in socks for a brief time before she orders him to take the socks off as well. Now the trampling torture continues under her bare feet as she steps all over him again, on his chest, on his face and even on his throat - a human runway needs to endure this!
