I was talking to this girl, on the phone that I've only met once before.. We were just talking casually and then she mumbled what i could've sworn was "you're cute, lets fuck". I wasn't really sure what I heard so I asked her to repeat it and still heard the same thing...
So I said "I'm down",
she- "what?",
me- "down to fuck *slight laugh*"
(because i really don't know her that well yet and I figured it was a joke)
Then she says "wow typical all you're after is ass, bye" *hangs up*

So then i text her saying that i like what she just did, and she's a lot smarter than i give her credit, and she just replied "yep."

what do to now?
