Flirty Teacher Update

Well some of you may have read in my thread yesterday about my flirting teacher and some of you recommended I make small small moves. Well today I was in class and she was sat next to me showing me something then I dropped my pen. I made to pick it up then she said no that she'll get it, then she bent over and put her hand on my lap, quite close to my private area. And she really kind of 'stroked' my lap, in a way, she didnt just rest it there.
Is this a sign???
