My premature dick can't handle Wifey's perfect tight and wet pussy. So it's better kept locked up securely. Safe from any pressure to perform and disappoint, and feeling the only tightness I deserve. The tightness of my chastity cage.
Would you switch places with subby hubby, knowing you could grind and hump your poor locked up dick against my perfect butt, even though you would make your permanent lock-up only worse with that?
