My dear friend, it did happen. A co-worker of my wife who was then like a friend to me....
He came to our place for dinner and it was too late. This so called co-worker K stayed back at our place. It was raining heavily too.
I went to bed alone leaving my wife to chat him to discuss some upcoming presentation at their work.
....early morning he had left. I saw a bite mark on her neck in the morning when I wanted to kiss her neck after she was out of the bath.
I kept quite as I was confused...till... We went again to his place.....for a dinner....
