Fox walked around the apartment barefoot all day.. she collected a lot of dust with her soles and this means that her slave monica didnt mop the floor properly. Fox decides to give a lesson to a stupid slave so that this wont happen again in the future .. She orders the old woman to lick all the dust and dirt from her soles. monica throughly polishes Foxs soles with her tongue, swallowing all the dust in the process. Nasty dust pellets remain on monicas face. It looks pathetic but amuses Fox. Fox doesnt care that monica is her mothers age, because she demands that her orders be carried out on time and the apartment is always cleaned. You can compare Foxs feet before and after and evaluate the performance of the slave.
