I've encountered two real life situations of incest that ended in the incest couples eloping. One was a friend of mine who had a different father than one of his half-sisters. It's kind of amazing at all that they were so magnetically attracted to one another. The half-sister had two other sisters, and I personally thought they were far more attractive. So did everyone else. But the half-sister my friend fell for, was the oldest of the three half-siblings and she was 6 years older than my friend. They met for the first time during a Thanksgiving meeting when the father was showing my friend to his 3 half-sisters from a previous marriage for the first time. I watched. I was there. It was like fucking lightning struck them both when they first met. They couldn't keep their eyes off of one another the entire meal. I can't have been the only one to notice it either.
They were dating in secret three weeks later and having sex about 10 months into them secretly dating. They just couldn't help themselves around one another. I had no real opinions myself either way because why the hell would I care whose screwing who? Anyway, I briefly dated one of the other sisters and we went on like...group date things a few times. Anyway, it eventually became known because the sister I was dating, got into some kind of argument with her sister and ratted her incestuous relationship out to their mother. It got nasty for a while. I dumped her ass because that was a shitty thing to do to your sibling knowing the trouble it caused. Anyway, after about 4 months separated by their parents, both eventually said screw everyone and eloped. This was 8-9 years ago and I still keep in touch occasionally. They are still going strong several states over. He got a vasectomy because of reasons and she got her tubes tied because of reasons. They still can't resist one another. I've been to their house a few times and it's amazing that they can still look at one another in the way that they do. I just can't make myself see something wrong with it. They are intoxicated with eachother still 10 years later.
Another instance that ended in elopement was a guy and his sister being separated at birth, they were fraternal twins so twins but didn't look alike. They didn't meet until they were both 17. I was 13 at the time. I was friends with the little brother of the fraternal twin sister so I spent time at thew house and saw events unfold. Well, don't know when exactly they met, but they started dating when both were 17, about a week after they first met. Same story. Practically love at first sight. I don't normally believe in such a thing because love takes time....but I question that when I remember moments like this. Anyway, same story as the first. Dated openly though since no one knew their kinship yet at first. They were together even in college, went to same college. They got engaged at 22 after dating for 5 years. Not sure how it came to be known, but eventually it was discovered they were fraternal twins. The kind that don't look alike. Welp, marriage cancelled. Ensuing drama. Families try to keep them apart. This time, it lasted for 2 years. Both were 24 when the fraternal twin sister tried to hang herself, she just couldn't handle being separated from him. He was drinking like a fish to cope. Finally, after the failed suicide attempt, she and he eloped. Its been 5-6 years since they eloped. I haven't heard a word from them but my friend, the little brother of the sister says they are still together and being of age to drive, he travels to see them every summer.
So, incest to me, is a very hard subject to approach considering these two experiences I witnessed. I usually just keep silent.
