The longer you do something the less thrilling it will become... But Isabella is quite smart and as soon as it became a bit too easy to pull off, she started to do something a bit more. A regular game that came from her developing tastes was to sit and act normal in public but without her panties to cover her. That thought of anyone looking her way with just the right angle and noticing what she is doing... It's intense. To add to this, sometimes she will just slip her panties down to her ankles and hang out like that as an extra hint.
She has yet to be called out on her actions but she does wonder, how many have caught a glimpse of her during these games? Kids and the younger crowd would perhaps not think anything about it but adults would surely never be able to get it out of there heads for weeks... Ah~
