I like to think of it as a sort of story: she's always been dedicated to BWC ever since she was a young lady. And now that she's an elderly woman, even if she could have retired or moved on to a new job, she stuck around in the same position as a nurse to service white men like she always has.
And this is why being a nurse is the best job~ you get to examine all of the white studs that keep coming to you specifically, maybe they passed on to other's the fact you are such a well and caring nurse~ always relieving them from pain and stress and not to mention all the pent up sperm they have stored on those shiny balls, everyine coming with hard-ons and aching in agony to explode, there are even some people that havent clean their cocks or made an effort, the smell corrupting your brain but as your reputation proceeds you, they all get wash without problem and leave in the best conditions from the moment the entered your office.
