College study session

Lea and you are studying for tomorrow's economy test. You are alone and so far she has no idea about your secret but she's really giving you a hard time by playing with her feet and by dangling those worn flats. You just can't take your eyes of her feet and Lea notices you staring at her feet. "Hey, what are you doing? We are supposed to study?" Oh my god this is hell and heaven - her feet are so close but you can't do anything..."Hey you should study. Are you looking at my feet? No?". What to do to get closer to her feet. You unobtrusively let fall your pen under her chair, at least that's what you think, that she don't know but Lea is starting to suspect something is up. You take your time picking up the pen while Lea puts her feet on the table right next to your place. Yesss now you can see those feet perfectly. But wait a moment is she caressing her own feet? Is she taking off her shoes? She's teasing you! Is it possible she knows...?
