Joanne — Female has incest with brother and cousin, now in her 30s and wondering if incest is “right or wrong” (case narrative)

[This entry was initially posted to the second Red Keyhole blog (now inactive).]

This narrative, involving another case of consensual sibling incest between brother and sister — and incest with her cousin, resulting in 2 kids —has been drawn from an October 2010 “confessional” by a woman indentifying herself as Joanne, in her 30s, located in Los Angeles. Submitted in response to a survey on an online incest discussion forum, her narrative has been posted here because of its research interest and educational value.

Describing Joanne’s ongoing relationship with her older brother, from early adolescence into mature dulthood, this case narrative illustrates how sibling incest can begin through mutually powerful erotic attraction, and develop into a consistent, enjoyable sexual relationship. Cases such as this strongly suggest that such incest is more widespread than generally thought.


Brother-sister incest may begin at a very early age and continue well into mature adulthood.

While some incestuous relationships may be “experimental” among young siblings, the brother-sister erotic bond does sometime appear to be extremely strong, as this case underscores.The original narrative has been lightly edited to improve orthography and readability.


I am having a battle within myself if incest is right or wrong. My brother and I started having sex when I was 11 and he was 17. It was drilled into both our heads that incest is wrong and sinful.

At 13 my cousin started doing me; he was 35 at the time. He said incest is natural. My cousin and I have 2 children together. He is married, and was when it started with me at 13. He has a daughter 2 years younger than me and he gets her, too. Anyway, I have not seen my cousin in 5 years.

My brother and I still have sex. I am in my 30s now. I love incest stories, real stories that actually happened. I love just about everything about incest. But I still battle with myself about it being right or wrong.


Many brother-sister couples, often engaging in “illicit” extramarital relationships, report that violating the incest taboo heightens their erotic experience.
