>I just don't know how to gently reject My friend
If it comes up again, you tell her what you just told me. And you can even say it in a playful, laughing, joking manner if that's how she's presenting it (which may very well be Schroedinger's flirtation - she's joking as long as you are but she's not if you aren't), but you can say, "Yeah that would probably be hot but as you know I'm not into casual sex." Or maybe she doesn't know that and you can inform her of that. And if you want to be even more covering of your bases you can even just say "casual encounters" or something like that to rule out anything that "isn't sex".
