Clean my car's tires while I trample your hands!

Description: I order the slave to clean my car's tires with a toothbrush and his tongue - while i watch him closely and trample his hands under my brutal boots. i want some entertainment while watching him do his work ... and there's no better entertainment than his suffering. in between i move the car a few inches forward to give him a new piece of tire to clean every now and then - i want the whole tire to be clean again! obviously, he's in a lot of pain when i stand on his other hand with my full weight - flattening it between the brutal tread of my boot sole and the rough concrete of the parking lot! and he better does a good job ... otherwise i'll have to think of something even more painful as a punishment!
