Four dominants and two submissives share the same space, all of them barefoot. They have spent hours treading on the filthy floor, and even now, as they rest, they continue to scrabble their feet against the ground, eager to make their soles as black as possible. The submissives lie before them, ready to serve, their tongues extended to lick and clean the dirty feet. The dominants waste no time in rubbing their filthy soles on the submissives’ faces, leaving a trail of dirt on their tongues. The black color slowly spreads from the feet to the tongues, creating a nauseating sight. The dominants then use the submissives’ faces to polish the ground, rubbing their tongues and cheeks against the floor. The submissives are treated as mere rags to be used for cleaning purposes.
