Want to get into the lifestyle

So here it is I have been married for 25 years & want to kink it up, I have talked to the wife about this & role play pretending that we are with someone else, she says she wants to see me fuck another woman & I definitely want to see her taking a big cock, but she won't take the plunge. Would it be wrong for me to organise a meeting without her knowing that we are actually meeting & just pretend that we crossed paths by a coincidence.
