The foot slave's tongue works overtime, lapping at her Master's unwashed feet, each lick a testament to her devotion. She moves up his body, her tongue tracing the lines of his muscles, until she reaches his ass. She buries her face, her tongue exploring his filthy crack, tasting every inch of him. He grows hard, his cock pushing into her mouth, testing her limits. She gags, but she's determined to clean him, to take all of him. He uses her, his cock slamming into her throat, his hands gripping her hair, pushing her down, making her take it all. She chokes, but she never stops, until he's clean, until he's cumming down her throat.
