I have been attracted to my step daughter since she was 14. It was Halloween and she had on a sexy costume, and suddenly it was like I was seeing her in a whole new light. She's 18 now, going on 19. Her mother and I broke up a couple of years ago, and my sd recently came back into my life. She's even hotter now. She's estranged from her mother and still considers me a father. She's in a bad position and I want to help her out, get her into school and help her find a place to live, give her a sense of stability. But I also really want to fuck her! I can't help it!

I have a girlfriend of nearly two years who would be heart broken if she knew I was thinking of my sd when I was fucking her. I feel like if I acted on these feelings it would ruin my life, and who knows if she would even be interested. Yet whenever I'm alone I think of her and jerk off. I want her so bad, what do I do?
