Mistress Gaia – Wetting A Dry Mouth

Im training my fresh slave as shoe licker, or better, as a shoe-sole licker. I have tied him down, so that he is entirely immobilized; he can only stir his tongue, which is the only thing he needs. Im not blessed of his performance, it seems that his tongue is too dry and he cannot produce enough saliva. But I have the right solution for that. I squat over his face and.... I let it go; soon his moth is full with my pee. He must be really thirsty, since he quickly drinks everything, without wasting a single drop. Now his tongue is nicely wet and he can resume his sole-ncleaning job.
