Many Different Boots Tried Out For Trampling

Ive brought so many nice boots - some boots, some high high-heeled slippers - all of them look like they were made for trampling! And Im going to test out a few of them on the slave now! Very first well embark with a pair of high high-heeled shoes - nice strappy ones with lean high-heeled slippers - and they make the slave scream in pain as I walk all over his body and his hands. Next up is a pair of boots with chunky heels, but a deep painful tread. After putting them on, I walk up his arms and then step on his chest to trample it. I try out another pair of heels and another pair of boots afterwards - and by now the slaves chest and stomach are covered in heel marks pretty well! How long will I make him suffer?
