奴隶的舌头做了很多工作

My shoes are dirty and I've been wearing them for a really long time. I take one of my slaves on a leash and put him to work licking them clean. Then he can sniff and lick my sweaty cheese socks. My feet are also sticky with sweat too, so he has to take care of them with his tongue as well. In between, to thank him, I spit in his mouth.
