Cock cages are for lazy Mistresses and slaves.

I’ve served several mistresses who believed in psychological castration and believed their slave, can respect their womanhood keep their cocks limp instead of hard.
Eliminating the need for your cock, they can train your mouth to serve all their needs. Erotic French kissing, cunnilingus, eating ass or using hands and fingers to please them.
They reserve the right to administer physical punishment with no safe words to train you to be a better slave.
Your ass belongs to mistress who can violate it with her cock whenever you need a good screwing.
When they find a safe male companion for you, you’ll be obligated to suck cock, and take it in the ass treating your buddy to the same medicine.
