Heinous Sock Water For The Slave

As a prize for following my orders, I suggest my slave a drink of water, which he gets to take in a very special way. He has to lie on his back in front of me with his mouth broad open. I take off my ankle boot and dip my dirty, foul-smelling and cheesy sock into his water cup. The water has now taken on the smell of my digusting sock! I take the water-soaked sock and put it into his mouth. He doesnt get much to drink so he has to suck every drop of water from my cheesy socks. Water is so infrequent and valuable to him that he greedily sucks!
