Girl giving me signals?

today in cl i was laying on the floor doing my work because my teacher allows us to. this girl, emily, comes over and sits down right in front of me. i didn't think anything of it until she slowly starts scooting back towards me. eventually she's about an inch or two away from me. then she leans forward and her starts gently rubbing my leg (btw she's wearing shorts). it stays like that then she reaches down her pants showing off half of her (im against a wall so no one else saw) and pulls out her lacey thong. then she turns around and starts talking about her . then i sit up and she sits in my lap, so i put my arms around her waist. she gets my hands, and puts them down her pants for me to finger her. THEN i lay back and she's laying on top of me on her stomach. is she telling me something?
