If your husband is wilful it can be useful to employ a young girl in her mid-to-late teens for obedience purposes.
She will administer punishment with zeal.
I have used nmy youngest member of staff in this capacity repeatedly and the more she does the better she gets.
The first time I chained my husband to her ankle for the entire day and when she brought him back to me that evening he couldn’t even speak.
I was so impressed that I made him wear a wireless webcam next time so as best to enjoy it with him.
