I've locked the slave in the face trampling box and now I want to use his tongue to wipe off the dirt of the soles of my flip-flops. But when I'm walking in flip flops, my feet also get extremely dirty over the day - and therefore I quickly get rid of the shoes and order the loser to lick my filthy bare feet instead. And since his face is basically part of my floor ... I sometimes just walk over his face a couple of times, before he has to get his tongue out and clean my feet again. I want my feet to be completely spotless again and he'll clean every single spot of my foot soles and suck every single toe until they're all clean as well!
