Sister in law

This is a true story, Many years ago my wife was very ill, as we had young children, times were hard, my sister in law used to come to help us of a week end, she had to travel from the country, She was a great help, on night I hugged her and gave her a very passionate kiss and cuddle, just to say thanks and to show her my appreciation, I didn’t mean anything into it, To my surprise, she was very receptive to it. After that I was keen to keep showing her my affection, unfortunately my wife passed away some months later, my SIL came down to assist me and my children again. Well on thing led to another, I snuck her into my bedroom very discreetly. Well talk about a bombshell, I hadn’t had sex with another lady for over 20 years, and hardly any fun for 18months, it was the first time I ever received oral sex, I was trying to be quiet so my daughters wouldn’t hear, I lasted about 30/40 seconds and I unloaded into her mouth, what a sensation, you told me next day that my cum tasted like caviar, then we had a 69 which was a first for me. I would lick her out for hours, she would climax and want me more, our sexy fun went on for a few months, it was fantastic, But all good things cum to an end, Now I am in a very cold relationship, and can only reminisce about it, Ken
