Unexpected [M]eet

So I was just spending my weekend at home with my wife and my friend knocks on my door. When I open the door its my good friend and next to him is my ex, who I had to part ways after being together for 4 years due to long distance relationship, when she had to move to a different city. And as always forbidden fruits are always beautiful. She had that glow on her face that I remember of. I was lost for words and I invited them in.

Once Inside I introduced her to my wife as an old friend to not make things awkward. My Ex told she was in town for a few days and my friend suggested she should stay in my place as she was yet to get a hotel. I was still trying to figure out what was happening and I agreed that she should stay in my place. My ex was hesitant but my wife, being non the wiser, insisted her to stay in our place and she obliged.
