Cleanup?

Is this the final step for a cuckold? Is it a rite of passage, an affirmation of your love for her, one last humiliating act? I understand I’m her sub and my only sexual gratification comes from my hand and knowing she sleeps with other men so I want to keep her happy. Any other cucks out there find themselves in this situation? Did you do it willingly. Any women have their cucks do this? Do you enjoy it?
