Is there a novel in which a brother or sister falls in love with his brother or sister?

Sister cherry tree in the midsummer of July 7, you are an angel who fell into the world and fell in love with another (sister). I have something to do with my sister Wen Wen (chapter 1-76, after reading it, you will feel that this is not just an erotic article, but also a little touched). I have an e-book version. If you want to see it, please tell me your email address. Japanese comics Sister Lovers and Angel Shelter are also good. Blue life and death love is a TV series, and there are also novels of the same name. I've seen it. It's not quite the same as the TV series. For example, in TV series, Sean hopes to be a tree in his next life, and in novels, Sean hopes to be a Na Pianhai in his next life. I want to remind readers that I hope everyone can correctly understand the author's writing intention, instead of supporting them to do things that violate the law and morality. So don't distort these works one-sidedly, let alone imitate them. Immature people should consciously not read such works to avoid being guided.
