46 [M4M] wife seeing her friend and I get to listen

Got delayed by a few days but the wife is going to see her friend tonight and we determined I get to listen. She agreed to allow me access to her phone microphone through an app so I can tune in and listen when I want. I told her whenever she has a friend over (not often) the part I enjoy most is listening to her from down the hallway.....this will be fun!
