I force my wife to be ** at times. I came home from work one day. It was a hot summer evening. I just said to her to take off her clothes so I can look at her. She rolled her eyes. This was before kids so it was just us alone together. I repeated what I said. She undressed. I motioned for her to turn around. She shuffled round. I kissed her and let her put her clothes back on.
Another evening I said I would like to see her naked and again after the usual excuses, she took off her clothes and I had her do a twirl for inspection. Then I had her stay naked until we went to bed.
Over time, I have conditioned her to obediently strip and stay naked and cook and serve meals.
