Mistress Mallory decides that for Bart's birthday he will receive a beating everyday for six days. Mallory wears a different outfit in each scene, including blouses, skirts, dresses, jeans, and lingerie. Each day the thrashing gets harder and harder as Mallory uses paddles, hairbrushes, straps, belts, fly swatters, single-tail whips, and a bullwhip. Mallory gets so turned on lashing Bart that she plays with herself while whipping him, and goes topless for the bullwhipping.
