Spitting Muscle!

We are back at the farm and I have My two slaves on their knees for some spittoon training. I love turning My boys into human spittoon receptacles that drink and swallow My special liquid. I find it a very intimate and intense way to further their submission. One slave is used to hold My water glass, he must hold it high without shaking until I command otherwise. It is apparent he is struggling early on as his little arms shake almost instantly, his muscles in his arms must be burning as he holds My glass above his head, fearful of punishment if he fails. I use them both, dribbling My saliva into their mouths. They are forbidden to swallow until I decide, the amount of liquid being held ever growing and the urge to gag becomes desperate. This just amuses Me even more as I keep spitting My special kiss until they are overflowing. The more they struggle the more I laugh!
