Boss Lena checked barefoot her warehouse in Cologne yesterday. You have to be able to eat from the floor, she had told her warehouse manager Müller over and over again. Müller is summoned to the bosss office because someone has to clean her feet now. Since Müller was repeatedly unreliable, the boss forces him to do it with his tongue. Lena enjoys how the poor man must clean not only her soles, but also the spaces between her toes with his wet tongue again and again.
