Girls, if you look at a guy and bite your lower lip?

Anonymous
I have been getting pretty friendly with this girl. We have been talking a lot and teasing and acting like 2 little kids arguing and stuff. We give each other a hard tim but we both know we are just joking and that what makes it so great. She looks at me a lot, gives me sly looks and smiles, laughs at my jokes etc. So today I was joking with her and she gave me a "sly" look and smiled, I looked away for a bit and when I looked back she was still looking at me and she was biting her lower lip and I gave her a smile. While I know there could be many reasons to bite your lip, do you think that, in this context, does it mean something more? Or am I over thinking it?
