Firstly:
1) Do you think she'd be up for it?
2) Have you discussed it with her?
If the answer is No to both of these, you have your first step.
Then, update your profile to give us some location information, and post a photo of your wife - preferably in stockings and suspenders - and one of us will follow-up....
And tell us what your expectations are, and what you want - just watching? Clean-up? Or more involved: Hum, Fem, Bi etc
... not that these matter - the Cuck will just does as he's told.
