Servant's task: The work of art

You know that my tasks are always challenging. And so this one will also challenge you in a very special way. Let your creativity run free, haha. You will do your best to meet my requirements. Wanking is not, I can tell you that much - we both know that your juice is completely useless. That's why it stays in the thick balls, of course. You'll do yourself more good in other ways! A picture of the evidence is of course obligatory... after all, I want to have something to laugh about.
