I invite the candidate into my office for a job interview and make it clear that the advertized job position is the lowest possible. I am looking for someone to be my personal human toilet. On his knees, I have him stretch out his tongue and lick the fresh sweat from my armpits. I tape his hands together and stretch my ass right in front of his face for a long thorough rimming of my unwashed hole. I push a dildo deep into my ass, then he must clean every trace of shit from it with his tongue. When the urge to piss overcomes me, I stick a hose into his mouth and piss into a funnel, so everything runs straight down his throat. Then I shit several loads directly into his mouth. I make him chew and swallow my poop, while he struggles with the big chocolate portion. I smear the remaining shit across his body and cock, while I jerk him. Once he swallowed everything, I reward the fully soiled toilet with an orgasm. The slave is desperate to prove that he can function as a reliable toilet for his strict boss.
