I have my share of cool or cold pee over the years and to me it is not as appealing, taste-wise, as getting while it is warm. The humiliation factor however takes a step or two up when consuming old/cold pee. Watching, hearing or knowing that a Mistress has just peed tends to add excitement to the scene but once that excitement has waned by being separated from the act of consumption it becomes more about servitude and humiliation to me.
