<human>: So I met this awesome girl (let's call her Sarah) over summer and we hit it off pretty well, but there's just one problem: she lives about 4,800 miles away. There's a chance she'll move back to my country permanently at some point soon though, so there's still hope.

We've been in pretty much permanent contact ever since she flew home, and there's been a lot of obvious flirting. I often joke about how great her boobs are, and she likes to send me photos of herself before she goes on a night out. The most recent photo she sent was of herself in a provocative pose whilst sunbathing, and when she sent it she said, "How's this for a spank bank pic? ;)" Does this sort of behaviour mean anything?

Also, another twist. Her best friend (whom I also talk to, I'll call her Natasha) keeps teasing me saying that I'm falling for this girl. I hardly ever talk to Natasha about Sarah, so don't understand why she'd suspect that. Is it possible that Sarah has asked her to make these comments to gauge my interest in her?

Any advice appreciated - I'm just trying to work out if the flirting, photos, and teasing from her best friend mean anything or not. Is she into me?

Give me the gist of the text in a nutshell
<bot>: clicked well and flirting with girl who currently lives far away but might come back. Any point waiting or is she not into me?
