Brother’s incest with sister — “Boyfriend-girlfriend” relationship produces “love child”, develops into ongoing adult incest (case narrative)

[This entry was initially posted to the original Red Keyhole blog on 6 July 2011.]

If there’s any real basis to genetic sexual attraction, it would seem to be implied by brother-sister incest that begins in adolescence, intensifies with erotic passion, produces a “love child”, and continues into adulthood. Such is the background of this case, based on a May 2010 “confessional” posting, submitted by a male respondent, identified as Michael, in Los Angeles, in response to a survey underway on an online incest discussion forum.

Excerpted here for its research interest and educational value, Michael’s narrative provides interesting insight on some of the details of consensual sexual experimentation between very young heterosexual siblings – as this blog has previously noted, “an aspect of childhood sexual development that is rarely discussed in public media and even professional studies, and indeed is nearly taboo.” As with several other cases posted on this blog, this case affords a particularly illuminating glimpse of some intimate aspects of pubescent or adolescent sexuality (invoking, as well, issues of the Youth sex taboo, and “age-of-consent” prohibitions against youth sex vs. an effective consent approach).

This case also provides another example of how early sexual experimentation between brother and sister can develop into more robust incest as the siblings mature into adults. Incestuous relationships often tend to be extraordinarily passionate, and this seems especially true of brother-sister relationships with onset in early adolescence.

Of particular interest, this case involves the very hot-button, ultra-taboo issue of incestuous pregnancy and procreation – with a “love child” the product of hot, passionate sibling incest.


Incestuous brother-sister relationships beginning in early adolescence can become extremely passionate.

Once again, it’s important to note that the sexual activity involving youths (brother 16, sister 14) below the capitalist state’s arbitrary “age of consent” apparently violates legal strictures – which Revolutionary Marxists (including this blog) oppose, counterposing instead the principle of effective consent. (See Age of consent issues and cases.) In addition, of course, incest itself is criminalized in the USA, UK, and many other countries.

The original narrative has been slightly edited to improve orthography and readability. Original language and style have been retained as much as possible – including very mature and sexually explicit language – in part to indicate such aspects as physical details, psychological dynamics, and emotional and moral attitudes.

My little sister was a slender blonde fox, with a cute face and beautiful breasts, hips and ass … and when I was 16 and she was 14, we spent a week together alone during summer vacation at my divorced mom’s house … and I seduced her into a week-long orgy of nudism and intercourse.

We had no birth control protection, so when we started fucking, I was careful and only had anal and oral sex with her … but pure instinct soon took over, and I started fucking her pussy and cumming inside her. She also felt the mating urge, and held me tight after I came to make sure my cum stayed inside her.

After non-stop sex for a day or two, we felt a closeness that only lovers feel … and she told me she wanted to be my girlfriend. I was in love with her, too, and we had a secret relationship as boyfriend and girlfriend throughout high school. We pretended to date others, but as soon as the dates were over, we snuck into each other’s beds and began fucking – we couldn’t keep our hands off one another, and sure enough, she became pregnant.

She decided to keep the baby – a girl – as our love child. Our daughter was born healthy and beautiful, and is a teenager now; my sister and I have both agreed we should initiate her into our private world of love and pleasure.
