My step-sister and I grew up very close. We had a crush on each other, but never talked about it. We have gone to trips, camping, safari; you name it, but never took it to the next level. We ended up both getting married, but still love to hang out with each other. I know that if I make a move on her, she would go for it; but I like the thrill I get from it like this and would like to just keep it a fantasy for now. Anyone can relate to this?
