Lisa is wearing her hard wedge boots and stands on her slaves head with perfect balance you can see her slave suffering as she stands on him with all of her body weight, he even at one point begs her to get off him only for her to refuse his request and she tells him to do another minute, those boots really hurt him on the hard cold concrete floor, she stands on him facing the camera for 2 and a half minutes then the rest of the clip is of her facing away from the camera.
