Left Alone Bound Blindfolded Naked and Exposed

As punishment, I leave my chastity sub restrained, blindfolded, naked, and completely exposed for hours, abandoned to the wait with no idea when I will return. The long isolation, weakness, and uncertainty wear him down until he is desperate for me to come back. When I finally return in the evening, I put his chastity cage back on before unrestraining him, making sure he ends the day locked, denied, and still fully under my control.
