It’s quite possible that Miss Rebekah of Strict Women is going out of her way to psychologically torment the men that she spanks.
For example, why give an over-the-knee spanking wearing nothing but stockings and skimpy, seductive lingerie? Is she torturing the poor male with the thought of fruits he cannot have?
And why use brush bristles to electrify the nerves in his well-spanked bottom? It serves no punitive function. It does, however, make him squirm and squeal like a little piglet.
