Slave disgust training

Today, my slave has to swallow everything. I spit on my shoes and the floor, and he has to lick up my snot. But that's not enough. To show him what he's worth, I piss in his pathetic mouth, and as punishment, he has to lick away everything he doesn't swallow, so that my floor is nice and clean again. Afterward, I allow him to cum on my shoes. But everything has its price, and of course, I make him lick up his own cum afterwards. After all, he has to know his place.
