Mistress BlackDiamoond - Drink for the prison slave

The slave has been locked in the cell for 24 hours and as we dont want him to be thirsty, we are merciful to him and give him a drink. Apparently hes happy too soon, because he didnt expect to have to drink our piss! One after the other, Alessia Jade, Goddess Vanessa, Anna Petrovna and I piss in the pot and he has to slurp the yellow champagne out of it!
