I’m horny to be cuckold

I am twice as old as my wife, but we are completely happy. One day, before going to work, I accidentally looked at her cell phone and saw that there was a message from her boss: “Can I come see you today? I said nothing, and went to work a little suspicious. I spent the whole day thinking about that message. I called her, but she didn’t answer, so I decided to go home early.
