She really likes spit! And she also likes to humiliate slaves! So she wants to combine both things... a good way to do so is to spit on her boots! She spits at them and the saliva runs slowly down to the ground. You can easily see the wet trace on them. Then she brays the spit with their soles on the ground. Now there boots are really messed up! But this is no problem - YOU will have to lick them clean again! Start now, boot licker!!!
