Mistress trains wife to lock husband in chastity

This frustrated wife is tired of how much time her husband spends masturbating, so she's brought him to my dungeon for some training. I know there's only one solution for this problem: chastity! I pull out a pink chastity cage and tell the wife all about the benefits of locking up her husband's pathetic cock. She's thrilled at the prospect of having total control of her husband's pleasure! I make the husband put the cage on, and then I give the only key over to his wife. Things are about to change for the better in their marriage!
