Obviously I am not the only person to have had sex with a sibling or aunts or cousins, but i believe my story is worth writing about.
At 12 years old I started exploring my sisters body who is 2 years younger. Mostly I started fingering her pussy. She enjoyed it and encouraged me. As we both grew into our teens it progressed to mutual masturbation, kissing and foundling her growing breasts and eventually oral sex. I am not sure why we never went all the way sexually except maybe we both were young. As we grew older we started dating each others friends where we both discovered full sex. By the time we were in our late high school years we had drifted apart and were dating people from outside of our circle of friends, you might say as normal maturing teens. She and I never reconnected in our affair but have always been close friends.
I had always had a fondness with one of my Aunts as she was the same age as me. As young teens I remember playing with her much the same way as my sister. In my early 20s she and I started innocently hanging out together. Eventually she made a sexual move on me by opening my pants and going down on me. That was the beginning of a 20 year off and on affair. She had very small breasts but her body was always young, fit and tight. so sexy. I wanted to marry and live with her but she wisely reminded me the rest of the family would not except that.
My cousin and I had flirted for years. When one day I was about 35, she called and asked if I was ever serious about some of the things I said to her. (she is 9 years younger, married, with two young children by this time) I was not sure how to answer but told her yes. A few long phone conversations proceeded. Eventually we made a date for sex only. She became the love of my life. Together and separately we shared every intimacy imaginable. she never left her husband but became my secret personal love slut for almost 3 decades. I do mean SLUT. She fucked some of her husbands friend and several of my mine. At one point of time during our affair I opened an account on AFF and advertised her as my wife seeking extra marital sex. For 3 years she dated 35 different men for sex only, with 6 to 10 meetings a month, some at their homes, some at motels and some in cars. Most were just once or twice, some became steadies and some became friends and lovers lasting for years. Aside from one man he though she had sex with just once, her husband never knew of her affairs and the slut she actually was. During all that time our love flourished. Our romance never stopped until at advanced ages we both moved away. We are still friends and stay in contact
