I had no idea Joanna was naked and changing into her bikini when I came in my mother's room to get her sun cover for her. But there she was, Mom's best friend, so beautiful and she just told me to stay, coming over to me to give me a kiss. Then she asked me to come over the next day for sexMy first-ever sex. What would you do? I know what I did and we became lovers that next day and for years after. She made me into a worthy lover and I have been grateful ever since and you will see why, especially with the surprise when I finally tell my mother about our affair.
