Slave has to lick disgusting street dirt and mud from my boots

Description: Today i'll get these boots nice and dirty ... and you're allowed to follow me around. but first, i've to go to the office - and my boot soles are still pretty clean - but that's about to change! after some appointments i finish work, drive for a while, stop at a gas station and use the disgusting gas station restroom - i don't even want to know what i stepped in there ... but then i'll finally go for a nice long walk. on the parking lot i step into some spit and gum - and then the muddy path in the woods. when i finally get back home and meet the slave, i show him the disgusting dirty soles and order him to start licking them clean. he has to start with the leather obviously - some of the mud got there as well - and only then he'll start cleaning the filthy soles. in between i spit into his mouth before he's allowed to continue cleaning my boots. it's so funny knowing that i carelessly stepped into all kinds of filth and this loser licks and swallows all of it ... obviously, i also tell him where i knowingly stepped in ... which makes it even more disgusting for him - and more funny for me!
