Crossed Legs Under Skirt Panty Tease

You are a guest of your hot milf neighbor. She makes you sit just in front of her while chatting. She wears a red costume with a short red skirt. She smiles and opens her long legs slightly, just enough for you to see what is underneath. She crosses and uncrosses her legs flashing her white panties. She knows that you can't stop looking up her skirt but looks like it doesn't bother her at all.
