When I was 13 I begged my stepdad to let me blow him. He'd been 'm****ting' me since I was five. He never once hurt or scared me and as I got older and turned into a horny teenager, I began to really like it. Mom was aware of what was going on and didn't care, because she'd been m****ted as a child too. In the beginning, she was always in the room when he played with me to make sure I wasn't hurt or scared. Mostly he would just sit me on his lap while naked and sort of bounce me up and down until he came. I wasn't bothered by it in the least. I loved him very much.

By the age of thirteen I understood what he was doing and was actually proud to have sex experience that my friends didn't. I asked him to let me suck his cock and was thrilled when he said I could. That was the first time my mom let me have alone time with him. She knew I was old enough to understand and felt that it was time to let us have the freedom to love each other in private.

Of course I had no idea what I was doing and he had to finish himself off with his hand. Over time I got better at it and we often traded oral sex with each other. Between my mom and me we kept him busy. Sometimes he would pleasure both of us in one night.

For my fifteenth birthday we had intercourse for the first time. Mom preferred that I get it from the safety of home and thought I was old enough. It was a very loving, pleasant experience. He treated me like a princess and it felt so good to finally have him inside me.

By this time he had started on my younger sister too. I came in one day and found her giving him oral. It turned me on but made me a little jealous too. Later that night he came to my room to make love to me, explaining that there was plenty of him to go around. So I let him have me.

Years later I've graduated college and still have sex with him. So do mom and my sister. I'm ready for a baby and want him to be the dad.
