I've put the slave's head in the box and also bound his hands and feet. Now he's completely trapped and I can use his mouth to clean my boots. Sometimes I stand on the box, sometimes I sit down on the barstool - but of course I'm rubbing my dirty boot soles all over his tongue all the time! So pathetic to see his tongue trying to reach all the dirty spots on my boots ... but that's just what a boot slave loser deserves!
