I stayed at my sister’s house recently, as I have done many times when my husband works away from home.
However, on this particular night, she was called into work at the hospital at short notice.
I went to bed early but got up to go to the bathroom.
As I passed her bedroom, the door was ajar and I heard moaning from inside where my brother-in-law was supposed to be sleeping.
I saw him through the crack in the door and, for some reason that I cannot fathom, I took a deep breath, opened the door and stood there watching him pleasure himself.
He got even more excited so then I dropped my dressing gown and joined him in the bed. We had fantastic s** and never said a word to each other. I know it was wrong.
I cant get him out of my mind.
