Blush and walk out quickly

You decide to make get out of the classroom as soon as possible trying to save yourself from anymore embarrassment, she is your best friend after all.
At lunch you see her on the other side of the common room casually chatting with some of her friends. She then makes eye contact with you and makes her way over to your side of the common room.
Once there she leans over, giving you a clear view of her cleavage, and whispers 'Did you like my thong John?', embarrassed you stutter and try and find the right words, however before you can even formulate a response she seductively says 'Meet me in the girls changing rooms straight after lunch and I might show you a bit more'
As she begins to walk off back to the other side of the room swinging her hips, she turns her head and winks at you then rejoins her friends.
