Chastity help

Why is my wife not really interested in locking my dick in chastity and completely dominating me? I've tried to give her the keys to the cage but she just gives them back. I want her to lock me up while she goes to fuck her big dick lover and call me moaning as he pounds it and tourcher me cause I wouldn't be able to play with myself... I'm still kinda dominating the situation but how do I teach her to take charge of me?
