We currently have a foreign visitor staying at our house. I really want to try and get with her in some way, but have no idea if she's interested.

I'm also worried that it could make things weird for the rest of her stay if she says no...

We've gone on a few walks and out to breakfast and it all seemed to go well. We even spent like 4 hours in the hot tub talking/drinking. But nothing ever happens.

Is there some way to ask if she's interested in a short fling before she returns home?
