Wife needs sexual relief

We are a couple in our 50's couple looking to spice up our love life. Wife is very horny these days and husband is unable to fulfill his duties because of medical condition. Rather than her finding a relationship on the side, I would like to set up a meeting with an anonymous man to to help meet her needs occasionally. Husband will always be present. We could meet in a bar and move on to a nearby hotel room. She and loves to perform oral on men. She can be submissive. We are both on the heavy side and wife prefers men with a little meat on their bones. This could be a one night stand or we could meet occasionally. I am very much in love with my wife so I will always be present. I may or may not participate. I may give her oral as she sucks your cock. You must wear protection, especially if you get a chance to fuck her.
