Ana Parra was 20 when she first met her estranged half brother, Daniel Parra – but the chemistry was immediate.
Now the Spanish pair, who have had two children together, are campaigning to reform the law so they can legally marry.
Ana had always been aware she had a half brother somewhere. During her childhood, she knew her father had left her to start a relationship with another woman, with whom he had children.
One of those children was Daniel, who said: "Someone had told me that maybe I had a sister out there, but my father never told me, it was something he wanted to hide."
Ana, eager to meet her sibling, found Daniel on Facebook and suggested that they meet. They say it was love at first sight,reports the Mirror.
"We didn't want to realise it," explained Ana, "we were angry with ourselves because it was hard to admit and break that taboo - we are siblings even though we didn't feel that way."
Their first kiss happened at a party. "We were partying, we approached each other slowly and gave each other our first kiss."
Ana recalled feeling "ashamed" of what happened, but Daniel described the moment as transformative: "That kiss broke all barriers, marked a before and after, it was like a reality check."
Several days later, they planned to see each other again, but were hesitant to acknowledge the romantic feelings.
Daniel said: "Imagine liking a girl and, for a moral reason, being forbidden to be with her. It's really hard to deal with."
