Sometimes Sarah walks her pet. rose crawls after her Mistress and licks her dirty boots. Sarah likes to humiliate her slave girl, she spits on the biton floor and orders rose to lick her spit. The slave girl licks every spit of Sarah off the dirty floor and swallows it. rose throughly licks the dirt off Sarah's soles, but they get dirty again when Sarah walks across the floor and rose has to lick the dirt again. Vicious circle.
