Ok. That's miscomunication on my part.
It wouldn't be "Hi, welcome to our home. Lets go screw."
We had a rough plan of maybe a series of visits, sort of like dating. To give her (and us) time to see if this relationship would even be feasable. Just how we'd go about that was something to be ironed out once/if she decided this was something she even wanted to attempt.
I hadn't even thought that anyone would get the impression that it would involve sex straight away. My apologies.
