New to this..

So ever since I can remember I’ve had a bit of a taboo kink. Always been a bit afraid to admit it but it is what it is. About ten years ago my estranged sister found me on Facebook(half sister if that makes any difference) and ever since then I’ve had this extreme desire to be intimate with her. Beyond a typical brother-sister relationship. As of recent I’ve finally mustered the courage to start flirting and she’s not acting all weirded out by it but she’s also not really adding any flame to the fire. I finally gave in and confessed what I felt and she responded a lot better than I thought, but still distant on the idea. She seems to be making it seem light hearted while the whole time she could have told me to just stop and whatnot. After I confessed she said something along the lines of “well of course you think I’m stunning. I’m your sister. I wouldn’t expect to think anything less of someone you want to be close to.” She hasn’t responded since. Im not sure how to proceed or even if I should. Maybe this is the sex gods telling me to just steer away from her. I don’t want to though… she’s the only sister I have and nobody can replace her nor do I want anyone else to have her. It’s quite the predicament 😂

Oh and hi, this is my first post!
