And this is why I love you

Hi, this is my first fan fiction I have ever written in my life, sorry if it's not to your taste. This includes explicit language, just pre warning you! And this why I love you is about a two friends who have a sexual relationship with one another even though they are married. Their names are Jo and Jake. They cannot keep secret their feelings for one another for much longer. They do not know what to do, do you?
