My foot soles are pretty dirty after walking around bare foot ... and the slave girl is locked in the facetrampling box - in the perfect position to lick them clean again! And on top of that, I can perfectly trample her dumb face in this position if she doesn't do her job to my satisfaction ... or just because it's fun for me! Again and again, I order her to lick my foot soles and suck my toes clean - and then walk over her face a couple of times or keep standing on it. The slave girl means in pain either way - just how I like it!
