Is it normal my sister enjoys erotic incest fiction?
I was on my sister's computer because she's the only one in the house that has Photoshop and I needed it for something. While I was on it I decided to snoop around and see what else she had on it. I'll admit that might have been wrong of me, but I was bored and curious. I found she had a very large collection of brother-sister incest erotic fiction, stored openly on a folder in her documents folder. It was a very large collection, I don't know if she could have read all of it. I would have just ignored it and assumed she just liked the erotic aspect more than the incest one, since I know she masturbates to books more than regular porn (though I kind of wish I didn't), but I found that for some of the stories where the brother and sister had names, she copied the story and replaced their names with mine and hers respectively. From this I think it's reasonable to assume she fantasizes about having sex with me, so I'm worried. I'm not going to confront her because I don't want to embarrass her and besides I was the one snooping. But it's going to make every time she touches, hugs, or kisses me very awkward if I think about it. Are these fantasies normal? Do other healthy girls have them without it impacting their relationships with their brothers?
