I know this much younger girl from my work, we barely know each other, though we talk every once in a while and I'm nice to her, treating her with respect and such while she does the same in turn. Now it's become apparent that she's obsessed with me and wants me to be her first. I already told her no on more than one occasion because not only am I spoken for, but even if I wasn't I'm more than a decade older than her and I could go to jail. In spite of me turning her down, she's been persistent. She keeps flirting and talking dirty to me when it's unwarranted, and even said that she'd let me cum inside her.
I tried telling her she should find someone in her own age range who loves and respects her, but she says all the boys she knows are too immature and would only want her for her body (and she IS a very beautiful young girl), and would rather have someone older and wiser, a guy who she can trust, like me.
No matter how much I try and let her down, she keeps trying for me. I don't want her to get into trouble with her job, and it would probably be a bit awkward if I went to her parents about it. But this has to stop somehow. How can I get this girl to back off?
