I just got back from my vacation and used the time for some extensive hikes - which made my hiking boots really dirty and the pair of hiking socks I wore all the time smell really disgusting. And both of these will make the slave suffer now! First, he has to lick the dirty top of my hiking boots while I laugh at him and enjoy seeing the original color of my boots again where he licked them clean. But in these boots, there's something way more disgusting for him ... the thick, sweat-drenched hiking socks that spend some many miles on my feet in these boots! He has to smell them extensively and take in the odor - before I put the boots back on - using his face as a foot stool! And then he'll have to clean the dirt-covered soles with the deep treat with his tongue as well! That's as close to a good vacation as this loser will ever get!
