A leather-clad dominatrix teaches her butt-plugged lesbian sub a lesson in submission and pain. The sub, gagged and tied, presents her ass for punishment. The mistress runs her fingers over the plug, then selects a whip, snapping it against her own thigh before lashing it across the sub's flesh. The sub yelps through her gag, but the mistress insists on silence, delivering more precise, harder strikes. She pauses to tease the sub's pussy, feeling it clench around her fingers before resuming the whipping, her own lust growing with each strike. She commands the sub to orgasm, the sub's body convulsing as the mistress brings her to peak with a final, brutal lash.
