Another uncommon betrayal

This is another contest by the @freewritehouse we are to write a story with 50words to be précised. The prompt word is "Abbey" and the word is used as a name in my story.

It was raining that night when I went to Abbey's house to give her a surprise visit. On getting there, I opened the door and screamed surprise but to my shock I was the one surprised. I met Kenneth and my girlfriend shirtless on the bed, then I walked out.

You can also put your hands to work and let's see the story you can make out of 50words.
