My husband lets me have sex with his friend

I can relate from the friends point of view. There was a sexual disconnect between my fuck buddy and her husband. He, worked long hours. She, needed sexual intimacy without strings. I was just a cock to play with which I didn't mind. Her husband knew we were fucking but did not know who I was. Our relationship came to a halt when husband retired and they moved away. The importance of it was she got that reaffirmation she was still desired and sexy. Husband was able to close out his career. I got pussy that my spouse was unable to provide. It was a win, win, win all around.
