Fern, a self-proclaimed "slave," surrenders her substantial ass to her partner's whims. He teases her, running the crop along her flesh, making her squirm. He snaps it down, leaving a satisfying mark. Fern gasps, her pussy throbbing with arousal. He continues, alternating between spanking and cropping, pushing her limits. Fern, lost in her submissive role, moans and begs, her body covered in a sheen of sweat, her ass a canvas of red welts.
