Boot Slave Trapped And Used

Ive put the slaves head in the box and also tied his arms and feet. Now hes downright 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 Im touching my dirty boot feet all over his tongue all the time! So pathetic to see his tongue trying to reach all the dirty spots on my boots but thats just what a boot slave loser deserves!
