Slave licking shoes and feet

What a nice slave I’ve got! He is so dutiful and almost always satisfies my dirty, even perverted wishes! Don’t you think such obedience should be rewarded? Ok, let me think. Today I let my boy lick on my dirty black shoes (I hope he will be grateful for this). Mmm, I taught my slave boy very well, just look how pleasingly and willingly he’s working with his tongue. Well, I’m gonna make a surprise to my submissive worm and give him my feet as a prize for all his pains!
