Just looking through a crack in the door to start with (you don't want to get too cocky and get caught), you see her taking her dress off and revealing some sexy lacey lingerie. She starts moaning and playing with her pussy. Fuck this is so hot and risky and you love it, you HAVE to get a closer look, you're that small she won't suspect a thing.
You start off by staring up at her fingering her wet pussy, playing with your tiny erect willy with your cute little hands. Getting braver you get even closer, exploring every inch of her giant body.
