Staining the white nylon
A good (or should I say bad?) mistress never avoids the dirty work. When a sub has to be taught a lesson, nobody should avoid getting dirty. Just like in this scene, where I work on this obedient butt with all my might, drilling the chute so that the poor guy whines in a perfectly submissive way. He??™s got his ass and sack all red and sore, but we??™re only starting.
