Frank Gun, the master of discipline, takes Sandra Parker under his stern tutelage, teaching her the ropes of bondage and the sweet, painful dance of submission. He whips her until her huge labia quiver, her body a canvas of welts and bruises. Frank's strong, dominant presence demands her full attention, and he rewards her obedience with tender clit massages, only to cruelly deny her release. He slaps her face hard, leaving a red handprint, and forces her to lick his boots clean. Sandra, a changed woman, surrenders completely to Frank's will, her body and mind now his to command.
