Turns out you can not only use the smother box for sitting on a slave's face - it's great for trampling too! I ordered my slave to put his head into it and then start trampling his face under my boots. I just love how you can see his face getting squished under the hard soles of the boots. Later I take my boots off and trample his face under my sweaty socks and bare feet too!
