Very Few People Know About It
“I’m in a long-term relationship with my biological half-sister on my mother’s side. I’m a male.
We didn’t grow up together; we actually didn’t meet until we were both almost thirty. Never knew each other at all until that point.
I had been trying to get in touch with her on and off for a decade or more, in a desire to meet the long-lost sibling and try to connect as family. I finally succeeded via online social networks and a bit of social engineering. We talked, purely online, on-and-off for about six months with some mostly-unacknowledged sexual tension making us both very uncomfortable. When we did finally acknowledge it, it came together very quickly and very powerfully. At the time, we were both in serious relationships; I was in a non-monogamous relationship and she was actually engaged and fully monogamous. My S/O knew all the details was 100% okay with it; her fiancé obviously had no idea. We agreed to meet up; we had a week of incredible sex and an insanely intense emotional connection equaled by no other relationship in my life, romantic or otherwise. It was a heady week.
Not long after that, we both ended our contemporary relationships (surprisingly mostly-amicably on her end; blood and fire on my end. No, I will not be telling that story.), I moved to be with her and we’ve going good ever since.
This is a true story, and I’ve attempted not to editorialize. This relationship is absolutely illegal where we live, and a VERY select few people know about it.”
