Boot Slave Disciplined With Spit

I ordered the slave to clean my boots and grind them with his tongue - but he didnt do a good job. I put him on a leash and Ill penalize him now. I know he hates slobber - so that will be his penalty! He has to munch my boots while I spit on his face again and again - and enjoy how much it disgusts him! And of course, I spit on the boots as well and coerce him to lick the spit from the boots! In the end, his whole face is covered with my spit - and then this loser will go outside with all the spit on his face!
